Oliver Goldsmith, son of the Reverend Charles Goldsmith, was born at Elphin, in the coun- ty of Roscommon, in Ireland, in the year 1729. His father had four sons, of whom Oliver was the third. After being well instructed in the classics, at the school of Mr. Hughes, he was admitted a sizer in Trinity College, Dublin, on the llth of June, 1744. While he re- sided there, he exhibited no specimens of that genius, which, in maturer years, raised his character so high. On the 27th of February, 1749, O. S. (two years after the regular time,) he obtained the degree of Bachelor of Arts. Soon after he turned his thoughts to the pro- fession of physic ; and, after attending some courses of anatomy in Dublin, proceeded to Edinburgh, in the year 1751, where he studied the several branches of medicine under the different professors in that university. His beneficent disposition soon involved him in unex- pected difficulties ; and he was obliged precipitately to leave Scotland, in consequence of having engaged himself to pay a considerable sum of money for a fellow student. The beginning of the year 1754, he arrived at Sunderlaud, near Newcastle, where he was arrested at the suit of one Barclay, a taylor in Edinburgh, to whom he had given security for his friend. By the good offices of Laughlin Maclane, Esq. and Dr. Sleigh, who were then in ii LIFE OF GOLDSMITH. the college, he was soon delivered out of the hands of the bailiff, and took his passage on board a Dutch ship to Rotterdam, where, after a short stay, he proceeded to Brussels. He then visited great part of Flanders ; and, after passing some time at Strasbourg and Louvain, where he obtained a degree of Bachelor in Physic, he accompanied an English gentleman to Geneva. It is undoubtedly a fact, that this ingenious unfortunate man made most part of his tour on foot. He had left England with very little money; and being of a philosophic turn, and at that time possessing a body capable ol sustaining every fatigue, and a heart not easily terrifi- ed by danger, he became an enthusiast to the design he had formed of seeing the manners of different-countries. He had some knowledge of the French language, and of music: heplav- ed tolerably well on the German flute ; which, from amusement, became, at some times, the means of subsistence. His learning produced him an hospitable reception at most of the re- ligious houses he visited ; and his music made him welcome to the peasants of Flanders and Germany. " Whenever I approached a peasant's house towards night-fall," he used to say, "I played one of my most merry tune?, and that generally procured me not only a lodging but subsistence for the next day: but, in truth" (his constant expression,) "I must own, when- ever I attempted to entertain persons of a higher rank, they always thought my perfor- mance odious, and never made me any return for my endeavours to please them." On his arrival at Geneva, he was recommended as a proper person for a travelling tutor to a young man, who had been unexpectedly left a considerable sum of money by his uncle Mr. S. ******. This youth, who was articled to an attorney, on the receipt of his fortune de- termined to see the world. During Goldsmith's continuance in Switzerland, he assiduously cultivated his poetical talent, of which he had given some striking proofs at the college of Edinburgh. It was from hence he sent the first sketch of his delightful epistle, called the Traveller, to his brother Henry, a clergyman in Ireland, who, giving up fame and fortune, had retired with an amiable wife to happiness and obscurity, on an income of only forty pounds a year. The great affection Goldsmith bore for this brother, is expressed in the poem before mentioned, and gives a striking picture of his situation. From Geneva Mr. Goldsmith and his pupil proceeded to the south of France, where the young man, upon some disagreement with his preceptor, paid him the small part of his salary which was due, and embarked at Marseilles for England. Our wanderer was left once more upon the world at large, and passed through a number of difficulties in traversing the greatest part of France. At length his curiosity being gratified, he bent his course towards England, and arrived at Dover, the beginning of the winter, in the year 1758. His finances were so low on his return to England, that he with difficulty got to the metro- polis, his whole stock of cash amounting to no more than a few half-pence. An entire stranger 'n London, his mind was filled with the most gloomy reflections in consequence of his embar- LIFE OF GOLDSMITH. iiv rassed situation. He applied to several apothecaries, in hopes of being received in the capa- city of a journeyman ; but his broad Irish accent, and the uncouthness of his appearance, occasioned him to meet with insult from most of the medical tribe. The next day, however, a chymist, near Fish-street, struck with his forlorn condition, arid the simplicity of his manner, took him into his laboratory, where he continued till he discovered that his old friend Dr. Sleigh was in London. " It was Sunday," said Goldsmith, " when I paid him a visit ; and it is to be supposed, in my best clothes. Sleigh scarcely knew me: such is the tax the unfortu- nate pay to p >veity. However, when he did recollect me, I found his heart as warm as ever; and he shared his purse and his friendship with me during his continuance in London." Gold- smith, unwilling to be a burden to his friend, a short time after, eagerly embraced an offer which was made him to assist the late Rev. Dr. Milner, in instructing the young gentlemen at the Academy at Peckham ; and acquitted himself greatly to the Doctor's satisfaction for a short time; but, having obtained some reputation by the criticisms he had written in the Monthly Review, Mr. Griffith, the principal proprietor, engaged him in the compilation of it; and resolving to pursue the profession of writing, he returned to London, as the mart where abilities of every kind were sure of meeting distinction and reward. Here he determined to adopt a plan of the strictest economy, and, at the close of the year 1759, took lodgings in Green-Arbour-Court, in the Okl Baily, where he wrote several ingenious pieces. His first works were The Bee, a weekly pamphlet; and Jin Inquiry into the present State of Polite Learning in Europe. The late Mr. Newberry, who, at that time, gave great encouragement to men of literary abilities, became a kind of patron to Goldsmith, and introduced him as one of the writers in the Public Ledger," in which his Citizen of the World originally appeared, under title of "Chinese Letters." Through the generosi y of Mr. Newberry, for whom he had written and compiled a variety of pieces, or, in other terms, had held the "pen of a ready writer," our Author was enabled to shift his quarters from Green-Arbour-Court to Wine-Olfice-Court, in Fleet-street, where he put the finishing stroke to his Vicar of Wakficll. Having conciliated the esteem of Dr. Johnson by that passport to the human heart, flattery, the Colossus of Literature gave so strong a recommendation of Goldsmith's Novel, that the Author obtained sixty pounds for the copy; a sum far beyond his expectation, as he candidly acknowledged to a literary friend. It was, however, a very seasonable relief, as it extricated our Author from many embarrassments un- (a) During this time (according to another account) he wrote for the British Magazine, of which Dr. Smollett was then editor, most of those Essays and Tales, which he afterwards collected and published in a separate volume- He also wrote occasionally for the Critical Review; and it was the merit which he discovered in criticising a despicable transla- tion of Ovid's Fasti, by a pedantic schoolmaster, and his Inquiry into the pmtent State of Learning in Europe, \vhicli first introduced him to the acquaintance of Dr. Smollett, who recommended him to several literati, and to most of the booksellers by whom he was afterwards patronized. a* iv LIFE OF GOLDSMITH. der which he then laboured. But as Goldsmith's reputation as a writer was not yet establish- ed, the bookseller was doubtful of the success of the Novel, and he kept the manuscript by him till the Traveller appeared, when he published it with great advantage. Among many other persons of distinction who were desirous to know him, was the Duke of Northumberland, and the circumstance that attended his introduction to that nobleman, is worthy of being related, in order to show a striking trait of his character. " I was invited," said the Doctor, " by my friend Percy, to wait upon the Duke, in consequence of the satisfac- tion he had received from the perusal of one of my productions. I dressed myself in the best manner I could, and, after studying some compliments I thought necessary on such an occa- sion, proceeded to Northumberland house, and acquainted the servants that I had particular business with his Grace. They showed me into an anti-chamber, where, after waiting some time, a gentleman, very elegantly dressed, made his appearance. Taking him for the Duke, I delivered all the fine things I had composed, in order to compliment him on the honour he had done me; when, to my great astonishment, he told me I had mistaken him for his master, *ho would see me immediately. At that instant the Duke came into the apartment; and I vas so confounded on the occasion, that I wanted words barely sufficient to express the sense f, entertained of the Duke's politeness, and went away exceedingly chagrined at the blunder I had committed." The Doctor, at the time of this visit, was much embarrassed in his circumstances ; but, vain of the honour done him, was continually mentioning it. One of those ingenious executors of the law, a bailiff, who had a writ against him, determined to turn this circumstance to hi? own advantage. He wrote him a letter, that he was steward to a nobleman who was charm- ed with reading his last production, and had ordered him to desire the Doctor to appoint a place where he might have the honour of meeting him, to conduct him to his Lordship. The vanity of poor Goldsmith immediately swallowed the bait: he appointed the British Coffee- house, to which he was accompanied by his friend Mr. Hamilton, the printer of the Critical [le'view, who in vain remonstrated on the singularity of the application. On entering the coffee-room, the bailiff paid his respects to the Doctor, and desired that he might have the honour of immediately attending him. They had scarce entered Pall-Mall, in their way to kis Lordship, when the bailiff produced his writ. Mr. Hamilton generously paid the money, and redeemed the Doctor from captivity. Dr. Goldsmith, in 1765, produced his poem of the Traveller, which obtained the commenda- lion of Dr. Johnson, who candidly acknowledged, "that there had not been so fine a Poem since the time of Pope." But such was his diffidence, that he kept the manuscript by him pome years; nor could he be prevailed on to publish it, till persuaded by Dr. Johnson, who furnished him with some ideas for its enlargement. This Poem, in consequence of the reception it met with from the public, enhanced his LIFE OF GOLDSMITH. v literary character with the booksellers, and introduced him to the notice of several persons eminent for their rank and superior talents, as Lord Nugent, Sir Joshua Reynolds, Dr. Nugent, Beauclerc, Mr. Dyer, &c. These distinguished characters were entertained with his conver- sation, and highly pleased with his blunders : at the same time they admired the elegance of his poems and simplicity of the man. He published, the same year, a Collection of Essays, which had previously appeared in the newspapers, magazines, and other periodical publica- tions. But The Vicar of Wakefield, published in 1766, established his reputation as a Novelist. Goldsmith's finances augmented with his fame, and enabled him to live in a superior style; for, soon after the publication of his Traveller, he changed his lodgings in Wine-Office-Court for a set of chambers in the Inner Temple ; and at the same time, in conjunction with Mr. Bolt, a literary friend, took a country house on the Edgware Road, for the benefit of the air, and the convenience of retirement. He gave this little mansion the jocular appellation of the Shoemaker's Paradise, being built in a fantastic style by its original possessor, who was one of the craft. In this rural retirement he wrote his History of England, in a Series of Letters from a Noble* man to his Son ; and, as an incontestible proof of the merit of this production, it was generally supposed to have come from the pen of Lord Lyttleton, one of the most elegant writers of his time: and it may be further observed, to enhance the reputation of the work, that it was never disavowed by that Noble Lord to any of his most intimate friends. It had a very extensive sale, and was introduced into many seminaries of learning as a most useful guide to the study of English history. It was a true observation with the Doctor, that "of all his compilations, his Selection of . ll'igliiih Poetry showed most the heart of the profession." To furnish copy for this work, it re- quired no invention, and but little thought: he had only to mark with a pencil the particular passages for the printer, so that he easily acquired two hundred pounds ; but then he observ- ed, lest the premium should be deemed more than a compensation for the labour, "that a man shows his judgment in these selections; and he may be often twenty years of his life in cul tivating that judgment." His Comedy of the Good-natured Man was produced at Covent-Garden Theatre in 1768, which, though it exhibited strong marks of genius, and keen observations on men and manner?, did not at first meet with that applause which was due to its merit. The baiiiff scene was generally reprobated, though the characters were well drawn ; but, to comply, however, with the taste of the town, the scene was afterwards greatly abridged. Many parts were highly applauded, as possessing great comic genius, and particularly that of Croaker, a character truly original, excellently conceived by the Author, and highly supported by Shuter, the most popular comedian of his day. The manner of his reading the incendiary letter in the fourth pet, and the expression of the different passions by which he was agitated, produced shouts vd LIFE OF GOLDSMITH. of applause. Goldsmith himself was so transported with the acting of Shuter, that he ex- pressed his gratitude to him before the whole company, assuring him, " he had exceeded his own idea of the character, and that the fine comic richness of his colouring made it almost appear as new to him as to any other person in the house." Dr. Johnson, as a token of his friendship for the Author, wrote the prologue. The production of this comedy added considerably to his purse, as, from the profits of his three nights, and the sale of the copy, lie acquired the sum of five hundred pounds, which, with an additional sum he had reserved out of the product of a Roman History, in 2 vols. 8vo. and an History of England, 4 vols. 8vo. he was enabled to descend fromtheattic story.heoccu- pied in the Inner Temple, and take possession of a spacious suit of chambers in Brook-Court, Middle Temple, which he purchased at no less a sum than four hundred pounds. He was at the further charge of furnishing his chambers in an elegant manner, fitting up a handsome library, and procuring every article, convenient and ornamental, that was proper for the ac- commodation of a man who stood high in the republic of letters, and whose talents were re- warded in a degree proportionate to their merit. But this improvement in his circumstances, and manner of living, by no means compensated for the mortification he underwent from the very-severe strictures of some rigid critics on his comedy. Sentimental writing was the prevailing taste of the town, with which a comedy, called False Delicacy, written by Kelly, abounded ; arid being got up at the Theatre in Drury Lane, under the superintendance of Mr. Garrick, it met with such general approbation, that it was per- formed for several successive nights with unbounded applause, and bore away the palm from "Goldsmith's comedy, which came out much at the same time at the other theatre. False Delicacy became so popular a piece, that ten thousand copies were sold in the course of only one season; and the booksellers concerned in the property, as a token of their acknowledg- ment of the merit of the comedy, apparent from its extraordinary sale, presented Kelly with a piece of plate of considerable value, and gave an elegant entertainment to him and his friends. These circumstances irritated the feelings of Goldsmith to so violent a degree, as to dissolve the bands of friendship between Kelly and him; for though, in every other instance, he bore a near resemblance to his own character of the Good Natured Man, yet, in literary fame, he " could bear no rival near his throne." Had not his countryman and lellow bard aspired at rivalship, had he been modestly content to move in an humbler sphere, he might not only have retained his friendship, but commanded his purse; but, as emphatically expressed by the same author from .whom we cited the last quotation; "To contend for the bow of Ulysses; this was a fault ; that way envy lay." There is a humorous anecdote related of Goldsmith concerning a periodical publication in which he was jointly concerned with Dr. Kenrick, BickorstafK and others. The publication dropped; upon which a friend remarked that it was a very short-lived production, and LIFE OF GOLDSMITH. v& had died a very extraordinary sudden death. "Not at all, Sir," said Goldsmith; "a very common case; it died of too many Doctors." But Goldsmith, soon disgusted with such trivial pursuits, applied himself to nobler subjects, and produced a highly finished Poem, called The Deserted Village. The bookseller gave him a note of a hundred guineas for the copy, which Goldsmith returned, saying to a friend, " It is too much ; it is more than the honest bookseller can afford, or the piece is worth." He estimated the value according to the following computation; " That it was near five shil- lings a couplet, which was more than any bookseller could afford, or, indeed, anv modern poe- try was worth :" but the sale was so rapid, that the bookseller, with the greatest pleasure, soon paid him the hundred guineas, with acknowledgment for the generosity he had evinced upon the occasion. . The author addresses this Poem to his friend Sir Joshua Reynolds. He writes in the cha- racter of a native of a country village, to which he gives the name of Auburn, and which he pathetically addresses. He then proceeds to contrast the innocence and happiness of a sim- ple and a natural state with the miseries and vices that have been introduced by polished life, and gives the following beautiful apostrophe to retirement: O blest retirement ! friend to life's decline, Retreats from care, that never must be mine ; How blest is he who crowns, in shades like these, A youth of labour with an age of ease ; Who quits a world where strong temptations try, And, since 'tis hard to combat, learns to fly ! For him no wretches, born to work and weep, Explore the mine, or tempt the dangerous deep ; No surly porter stands in guilty state, To spurn imploring famine from the gaie ; But on he moves to meet his latter end, Angels around befriending virtue's friend ; Sinks to the grave with unperceiv'd decay, While resignation gently slopes the way ; And all his prospects brightening to the last, His heaven commences ere the world be past !' The description of the parish priest (probably intended for a character of his brother Henry) would have done honour to any poet of any age. In this description the simile of the bird teaching her young to fly, and of the mountain that rises above the storm, are not easily to be paralleled. The rest of the poem consists of the character of the village school-master, and a description of the village ale-house; both drawn with admirable propriety and force; a descant on the mischiefs of luxury and wealth; the variety of artificial pleasures; the mise- ries of those who, for want of employment at home, are driven to settle new colonies abroad ; and concludes with the following beautiful apostrophe to poetry: '.nd thou, sweet poetry ! thou loveliest maid, (till first to fly where sensual jnys invade ; Jnfit, in these degenerate times of shame, To catch the heart, or strike for honest fame ; Dear charming nymph ! neglected and decried, My shame in crowds, my solitary pride ; Thou source of all my bliss, and all my woe, That found'st me poor at first, and keep'st me so; Thou guide, by which the nobler arts excel, Thou nurse of every virtue, fare thee well, The Doctor did not reap a profit from his poetical labours equal to those of his prose. The viii LIFE OF GOLDSMfTH. Earl of Lisburne, whose classical taste is well known, one day at a dinner of the Royal Acade- micians, lamented to the Doctor his neglecting the muses, and inquired of him why he forsook poetry, in which he was sure of charming his readers, to compile histories and write novels? The Doctor replied, 'My Lord, by courting the muses I shall starve; but by my other labours, I eat, drink, have good clothes, and enjoy the luxuries of life.' This finished Poem was by no means a hasty production ; it occupied two years in com- posing; and was the effect of the most minute observation, during an excursion of between four and five years. Soon after the appearance of this work, he paid a tribute to the merit of Dr. Parnell, in a Life prefixed to a new Edition of that elegant writer's " Poems on several occasions ;" a work that does honour to the head and heart of the author. The next Comedy the Doctor produced was in the year 1772: it was called, She Stoops to Conquer, and proved more successful than the Good-natured Man. Colman, who was then manager of Covent-Garden Theatre, and had given incontestible proofs of dramatic genius in the production of various excellent pieces, was greatly mistaken in his judgment of this comedy, which he thought too farcical, and had consigned to condemnation at the time of its last re- hearsal. Indeed, the performers, in general, coincided with the manager in opinion. The piece, however, notwithstanding the sentence pronounced by that acknowledged critic, was received with great applause, to his mortification, and the exultation of the author, who was not a little piqued at the critic from the following circumstance. The first night of the performance of his comedy, Goldsmith did not come to the house till it approached the close, having been ruminating in St. James's Park on the very important decision of the fate of his piece then pending; and such were his anxiety, and apprehension of its failure, that he was with great difficulty prevailed on to repair to the theatre, on the sugges- tion of a friend, who pointed out the necessity of his presence, in order to take cognizance of any passages that might appear objectionable, for the purpose of omission, or alteration in the repetition of the performance. Our Author, with an expectation suspended between hope and fear, had scarcely entered the passage that leads to the stage, than his ears were shock ed at a hiss, which proceeded from the audience, as a token of their disapprobation of the farcical supposition of Mrs. Hardcastle's being so palpably deluded, as to conceive herself at the distance of fifty miles from her house, when she was not at the distance of fifty yards. Such was the tremor and agitation of the Doctor on this unwelcome salute, that, running up to the manager, he exclaimed, "What's that?" Pshaw! Doctor,'' replied Colman, in a sar- castic tone, " don't be terrified at squibs, when we have been sitting these two hours upon a barrel of gunpowder." 1 Goldsmith's pride was so hurt by the poignancy of this remark, that the friendship which had before subsisted between the Manager and the Author was dissolved for life. The success of the comedy of She Stoops to Conquer produced a most illiberal personal at- LIFE OF GOLDSMITH. ix tack on the author in one of the public prints. Enraged at this abusive publication, Dr. Gold- smith repaired to the house of the publisher, and, after remonstrating on the malignity of this attack on his character, began to apply his cane to the shoulders of the publisher, who, making a powerful resistance, from being the defensive soon became the offensive combatant. Dr. Kenrick, who was sitting in a private room of the publisher's, hearing a noise in the shop, came in, put an end to the fight, and conveyed the Doctor to a coach. The papers instantly teemed with fresh abuse on the impropriety of the Doctor's attempting to beat a person in his own house, on which, in the Daily Advertiser of Wednesday, March 31, 1773, he inserted the following address. ' TO THE PUBLIC. ' Lest it may be supposed that I have been willing to correct in others an abuse of which I have been guilty myself, I beg leave to declare, that, in all my life, I never wrote, or dictated, a single paragraph, letter, or essay, in a newspaper, except a few moral essays, under the character of a Chinese, about ten years ago, in the Ledger; and a letter, to which I signed my name, in the St. James's Chronicle. If the liberty of the press therefore has been abused, I have had no hand in it. ' I have always considered the press as the protector of our freedom, as a watchful guar- dian, capable of uniting the weak against the encroachments of power. What concerns the public, most properly admits of a public discussion. But of late, the press has turned from defending public interest, to making inroads upon private life; from combating the strong, to overwhelming the feeble. No condition is now too obscure for its abuse, and the protector is become the tyrant of the people. In this manner the freedom of the press is beginning to sow the seeds of its own dissolution; the great must oppose it from principle, and the weak from fear; till, at last, every rank of mankind shall be found to give up its benefits, content with se- curity from its insults. ' How to put a stop to this licentiousness, by which all are indiscriminately abused, and by which vice consequently escapes in the general censure, I am unable to tell ; all I could wish is, that, as the law gives us no protection against the injury, so it should give calumniators no shelter after having provoked correction. The insults which we receive before the public. by being more open, are the more distressing; by treating them with silent contempt, we do not pay a sufficient deference to the opinion of the world. By recurring to leg:il redress, we too often expose the weakness of the law, which only serves to increase our mortification by failing to relieve us. In short, every man should singly consider himself as a guardian of the liberty of the press, and, as far as his influence can extend, should endeavour to prevent its licentiousness becoming at last the grave of its freedom. 6 'OLIVER GOLDSMITH.' x LIFE OF GOLDSMITH. The profits arising from his two comedies were estimated at 1300, rating the Good-natured Man at 500, and She Stoops to Conquer at 800, which, with the product of other works, amounted, as is asserted upon a good authority, to 1800; but, through a profuse liberality to indigent authors, and particularly those of his own country, who played on his credulity, to- gether with the effects of a habit he had contracted for gaming, he found himself, at the close of that very year, not in a state of enjoyment of a pleasing prospect before him, but enveloped in the gloom of despondency, and all the perplexities of deht, accumulated by his own indiscretion. It is remarkable, that, about this time, our Author altered his mode of address; he rejected the title of Doctor, and assumed that of plain Mr. Goldsmith. This innovation has been at- tributed to various causes. Some supposed he then formed a resolution never to engage as a practical professor in the healing art; others imagined that he conceived the important ap- pellation of Doctor, and the grave deportment attached to the character, incompatible with the man of fashion, to which he had the vanity to aspire ; but, whatever might be his motive, he could not throw off the title, which the world imposed on him to the day of his death, and which is annexed to his memory at the present day; though he never obtained a degree su- perior to that of Bachelor of Physic. Though Goldsmith was indiscreet, he was, at the same time, industrious ; and, though his genius was lively and fertile, he frequently submitted to the dull task of compilation. He had previously written Histories of England, Greece, and Rome; and afterwards undertook, and finished, a work, entitled, An History of the Earth and Animated Nature, His last production, Retaliation, though not intended for public view, but merely his own private amusement, and that of a few particular friends, exhibits strong marks of genuine humour. It originated from some jokes of festive merriment on the Author's person and dialect, in a club of literary friends, where good nature was sometimes sacrificed at the shrine of wit and sarcasm; and as Goldsmith could not disguise h^s feelings upon the occasion he, was called upon for retaliation, which he produced the very next club meeting. It may not be so accurate as his other poetical productions, as he did not revise it, or live to finish it in the manner he intended; yet high eulogiums have been passed on it by some of the first characters in the learned world, and it has obtained a place in most o.f the editions of the English Poets. Our Author no\v approached the period of his dissolution. He had been frequently attack- ed for some years with a strangury, and the embarrassed state of his affairs aggravated the violence of the disorder, which, with the agitation of his mind, brought on a nervous fever, LIFE OF GOLDSMITH. xi that operated in so great a degree, that he exhibited signs of despair, and even a disgust with life itself. Finding his disorder rapidly increase, he sent for Mr. Halves, his apothecary, as well as in- timate friend, to whom he related the symptoms of his malady. He told him he had taken two ounces of ipecacuanha wine as an emetic; and expressed a great desire of making trial of Dr. James's fever powders, which lie desired him to send him. The apothecary represent- ed to his patient the impropriety of taking this medicine at that time ; but no argument could prevail with him to relinquish his intention; so that Mr. Hawes, apprehensive of the fatal consequences of his putting this rash resolve into execution, in order to divert him from it, requested permission to send for Doctor Fordyce, who attended immediately, on receiving the message. Doctor Fordyce, of whose medical abilities Goldsmith always expressed the highest sense, corroborated the opinion of the apothecary, and used every argument to dissuade him from taking the powders ; but, deaf to all the remonstrances of his physician and friend, he fatally persisted in his resolution; and when the apothecary visited him the follow- ing day, and inquired of him how he did, he fetched a deep sigh, and said, in a dejected tone, " He wished he had taken his friendly advice last night." Doctor Fordyce, alarmed at the dangerous symptoms which the disorder indicated, thought it necessary to call in the advice of another physician ; and accordingly proposed sending for Doctor Turton, of whom he knew Goldsmith had a great opinion. The proposal was acceded to; a servant was immediately despatched with a message ; and, on his arrival, the two doctors assisted at a consultation, which they continued regularly every day till the disorder put a period to the existence of their patient, on the fourth day of April, 1774, in the 45th year of his age. His friends, who were very numerous and respectable, had determined to bury him in Westminster-abbey : his pall was to have been supported by Lord Shelburne, Lord Louth, Sir Joshua Reynolds, the Honourable Mr. Beauclerc, Mr. Edmund Burke, and Mr. Garrick ; but, from some unaccountable circumstances, this design was dropped; and his remains were privately deposited in the Temple burial-ground, on Saturday, the 9th of April ; when Mr. Hugh Kelly, Messrs. John and Robert Day, Mr. Palmer, Mr. Etherington, and Mr. Hawes, gentlemen who had been his friends in life, attended his corpse as mourners, and paid the last tribute to his memory. A subscription, however, was afterwards raised by his friends, to defray the expense of a marble monument, which was placed in Westminster-abbey, between Gay's monument -and the Duke of Argyle's, in the Poet's corner, with the following Latin inscription, written by his friend Dr. Samuel Johnson : Xll LIFE OF GOLDSMITH.

This monument is raised to the memory of OLIVER GOLDSMITH, Poet, Natural Philosopher, and Historian, who left no species of writing untouched, or unadorned by his pen, whether to move laughter, or draw tears : he was a powerful master over the affections, though at the same time, a gentle tyrant ; of a genius at once sublime, lively, and equal to every subject : in expression at once noble, pure, and delicate. His memory will last as long as society retains affection, friendship is not void of honour, and reading wants not her admirers. He was born in the kingdom of Ireland, at Femes, in the province of Leinster, Where Pallas had set her name, Nov. 29, 1731. He was educated at Dublin, and died in London, April 4, 1774. We insert the following lines, in verse and prose, written by a friend immediately after his death, as they were deemed faithful transcripts of his character. Here rests, from the cares of the world and his pen, A poet, whose like we shall scarce meet again ; Who, though form'd in an age when corruption ran high, And folly alone seem'd with folly to vie ; When genius, with traffic too commonly train'd, Recounted her merits by what she hacPgain'd ; Yet spurn'd at those walks of debasement and pelf, And in poverty's spite dar'd to think for himself. Thus free'd from those fetters the muses oft bind, He wrote from the heart to the hearts of mankind ; And such was the prevalent force of his song, Sex, ages, and parties, he drew in a throng. The lovers 'twas theirs to esteem and commend, /for his Hermit had prov'd him their tutor and friend : > The statesmen, his politic passions on fire, Acknowledg'd repose from the charms of his lyre. The moralist too had a feel for his rhymes, For his Essays were curbs on the rage of the times ; Nay, the critic, all school'd in grammatical sense, Who look'd in the glow of description for sense ; Reform'd as he read, fell a dupe to his art, And confess'd by his eyes what he felt at his heart. Yet, blest with original powers like these, His principal force was on paper to please ; Like a fleet-footed hunter, though first in the chace, On the road of plain sense he oit slacken'd his pace ; Whilst dullness and cunning, by whipping and goring, Tlieir hard-footed hackneys paraded before him ; Compounded likewise of sucli primitive parts, That his manners alone would have gain'd him our hearts. So simple in truth, so ingenuously kind, So ready to feel for the wants of mankind ; Yet praise but an author of popular quill, His flux of philanthropy quickly stood still; Transform'd from himself, he grew meanly severe, And rail'd at those talents he ought not to fear. Such then were his foibles ; but though they were such As shadow'd the picture a little too much, The style was all graceful, expressive ind grand, And the whole the result of a masterly hand. LIFE OF GOLDSMITH. xiii The prosaic eulogium which follows, does the highest honour to his character, both literary and personal. " In an age when genius and learning are too generally sacrificed to the purposes of ambi- tion and avarice, it is the consolation of virtue, as well as its friends, that they can commemo- rate the name of Goldsmith as a shining example to the contrary. " Early compelled (like many of the greatest men) into the service of the muses, he never once permitted his necessities to have the least improper influence on his conduct; but, know- ing and respecting the honourable line of his profession, he made no farther use of fiction, than to set off the dignity of truth; and in this he succeeded so happily, that his writings stamp him no less the man of genius, than the universal friend of mankind. " Such is the outline of his poetical character, which, perhaps, will be remembered, whilst the first rate poets of this country have any monuments left them. But, alas ! his noble and immortal part, the good man, is only consigned to the short-lived memory of those who are left to lament his death. " Having naturally a powerful bias on his mind to the cause of virtue, he was cheerful and indefatigable in every pursuit of it; warm in his friendship, gentle in his manners, and in every act of charity and benevolence, " the very milk of human nature." Nay, even his foi- bles, and little weaknesses of temper, may be said rather to simplify than degrade his under- standing; for, though there may be many instances adduced, to prove he was no man of the ivorld, most of those instances would attest the unadulterated purity of his heart. One who esteemed the kindness and friendship of such a man, as forming a principal part of the happi- ness of his life, pays this last sincere and grateful tribute to his memory," The esteem in which our Author was held by Dr. Johnson, is evident from the following passage, extracted from a letter of the Doctor to Mr. Boswell, soon after his demise. " Of poor dear Dr. Goldsmith there is little to be told, more than the papers have made public. He died of a fever, made, I am afraid, more violent by uneasiness of mind. His debts be- gan to be heavy, and all his resources were exhausted. Sir Joshua Reynolds is of opinion, that he owed no less than two thousand pounds. Was ever poet so trusted before ?" To so high a degree of literary fame did Goldsmith arrive, that the product of his writings in general is said to have amounted, in the course of fourteen years, to more than 8000, but this sm WHS dissipated by an improvident liberality without discrimination of objects, and other foibles incidental to mankind, which our Author could not see in himself; or, if he could see, wanted resolution to correct. But with these foibles he possessed many virtues, and those particularly of humanity and benevolence, which disposed him to do all the good within his power ; so that he lived respected, and died lamented. "Thepersr. of Goldsmith," (says Mr. Boswell, in his Life of Dr. Johnson,) "was short; his countenance coarse and vulgar ; his deportment that of a scholar, awkwardly affecting the LIFE OF GOLDSMITH. complete gentleman. No man had the art of displaying, with more advantage as a writer, whatever literary acquisitions he made. His mind resembled a fertile but thin soil ; there was a quick but not a strong vegetation of whatever chanced to be thrown upon it. No deep root could be struck. The oak of the forest did not grow there ; but the elegant shrubbery, and the fragrant parterre, appeared in gay succession. It has been generally circulated, and believed, that he was a mere fool in conversation. In allusion to this, Mr. Horatio Walpole, who admired his writings, said, he was "an inspired idiot;" andGarrick describes him as one: -for shortness call'd Noll, Who wrote like an angel, and talk'd like poor P"M. t But, in reality, these descriptions are greatly exaggerated. He had, no doubt, a more than common share of that hurry of ideas, which we often find in his countrymen, and which some- times introduces a laughable confusion in expressing them. He was very much what the French call un et vurdie ; and from vanity, and an eager desire of being conspicuous wherever he was, he frequently talked carelessly, without any knowledge of the subject, or even with- out thought. Those who were any ways distinguished, excited envy in him to so ridiculous an excess, that the instances of it are hardly credible. He, I am told, had no settled system of any sort, so that his conduct must not be too strictly criticised; but his affections were social and generous ; and when he had money, he bestowed it liberally. His desires of ima- ginary consequence frequently predominated over his attention to truth. In the opinion of many of the literati, Goldsmith rivalled in prose writing, and even sur- passed, Dr. Johnson. His prose has been admitted as the model of perfection, and the stan- dard of the English language. Dr. Johnson says, "Goldsmith was a man of such variety of powers, and such felicity of performance, that he seemed to excel in whatever he attempted; a man who had the art of being minute without tediousness, and general without confusion ; whose language was capacious without exuberance; exact without restraint; and easy with- out weakness." The most admired of his prosaic writings are the Vicar of Wakefield, Essays, Letters from a Nobleman to his Son, and Life of Parnetl. With respect to the Vicar of Wakefield, it is certainly a composition which has justly merit- ed the applause of all discerning persons as one of the best novels in the English language. The diction is chaste, correct, and elegant. The characters are drawn to the life ; and the scenes it exhibits are ingeniously variegated with humour and sentiment. The hero of the piece displays the most shining virtues that can adorn relative and social life ; sincere in his professions, humane and generous in his disposition, he is himself a pattern of the character he represents, enforcing that excellent maxim, that example is more powerful than precept. LIFE OF GOLDSMITH. xv His wife is drawn as possessing many laudable qualifications; and her prevailing passion for external parade is an inoffensive foible, calculated rather to excite our mirth than incur our censure. The character of Olivia, the Vicar's eldest daughter, is contrasted with that of So- phia, the younger; the one being represented as of a disposition gay and volatile, the other as rather grave and steady; though neither of them seems to have indulged their peculiar propensity beyond the bounds of moderation. Upon a review of this excellent production, it may be truly said, that it inculcates the purest lessons of morality and virtue, free from the rigid laws of stoicism, and adapted to attract the esteem and observation of every ingenious mind. It excites not a thought that can be injuri- ous in its tendency, nor breaths an idea that can offend the chastest ear; or, as it has been expressed, the language is such as "angels might have heard, and virgins told." The writer, who suggested this pleasing idea, observes further, that, " if we do not always admire his knowledge or extensive philosophy, we feel the benevolence of his heart, and are charmed with the purity of its principles. If we do not follow, with awful reverence, the majesty of his reason, or the dignity of the long-extended period, we at least catch a pleasing sentiment in a natural and unaffected style." Goldsmith's merit, as a poet, is universally acknowledged. His writings partake rather of the elegance and harmony of Pope, than the grandeur and sublimity of Milton; and, as we ob- served before, from the authority of Dr. Johnson, he rivals every writer of verse since the death of Pope; and it is to be lamented that his poetical productions are not more numerous; for though his ideas flowed rapiJly, he arranged them with great caution, and occupied much time in polishing his periods, and harmonizing his numbers. His most favourite Poems are the Traveller, Deserted Village, Hermit, and Retaliation. These productions may justly be ranked with the most admired works in English Poetry. The Traveller delights us with a display of charming imagery, refined ideas, and happy ex- pression. The characteristics of the different natiqns are strongly marked, and the predilec- tion of each inhabitant in favour of his own ingeniously described. The Deserted Village is generally admired : the characters are drawn from the life. The descriptions are lively and picturesque ; and the whole appears so easy and natural, as to bear the semblance of historical truth more than poetical fiction. The Hermit holds equal estimation with the rest of his poetical productions; and its beau- ties did not fail to attract the notice of the artist. The subject is delineated in a masterly manner by the pencil of Mr. Kirk, to which ample justice is done by the engraving of Mr. Anker Smith ; and, through the united skill of those ingenious artists, produces a very chaste and elegant vignette. His last poem of Retaliation, to which we have before adverted, is replete with humour, free LIFE OF GOLDSMITH. from spleen, and forcibly exhibits the prominent features of the several characters to which it alludes. Dr. Johnson, as reported by Mr. Boswell, sums up his literary character in the following concise manner. " Take him [Goldsmith] as a Poet, his Traveller is a very fine per- formance, and so is his DeSerted Village, were it not sometimes too much the echo of his Tro- veller. Whether we take him as a poet, as a comic writer, or as an historian, he stands in the first class." HISTORY OF THE EARTH. CHAPTER 1. A SKETCH OF THE UNIVERSE. HHHE world may be considered as one vast mansion, where man has been admitted to enjoy, to admire, and to be grateful. The first desires of savage nature are merely to gratify the importunities of sensual appetite, and to neglect the contemplation of things, barely satisfied with their enjoyment : the beauties of nature, and all the wonders of creation, have but little charms for a being taken up in obviating the wants of the day, and anxious for precarious subsistence. Philosophers, therefore, who have testified such surprise at the want of curiosity in the ignorant, seem not to consider that they are usually employed in making provisions of a more important nature ; in providing rather for the necessities than the amusements of life. It is not till our more pressing wants are sufficiently supplied, that we can attend to the calls of curiosity; so that in every age scien- tific refinement has been the latest effort of human industry. But human curiosity, though at first slowly excited, being at last possessed of leisure for indulging its propensity, becomes one of the greatest amusements of life, and gives higher satisfactions than what even the senses can afford. A man of this disposition turns all nature into a magnificent theatre, replete with objects of wonder and surprise, and fitted up chiefly for his happiness and entertainment : he industriously examines all things, from the minutest insect to the most finished animal; and, when his limited organs can no longer make the disquisition, he sends out his imagi- nation upon new inquiries. Nothing, therefore, can be more august and striking than the idea which his reason, aided by his imagination, furnishes of the universe around him. Astronomers tell us, that this earth which we inhabit forms but a very mi- nute part in that great assemblage of bodies of which the world is composed. It is a mil- lion of times less than the sun, by which it is enlightened. The planets also, which, like it, are subordinate to the sun's influence, ex- ceed the earth a thousand times in magni- tude. These, which were at first supposed to wander in the heavens without any fixed pathj and that took their name from their ap- parent deviations, have long been found to perform their circuits with great exactness ancl strict regularity. They have been dis- covered as forming, with our earth, a system of bodies circulating round the sun, all obe- dient to one law, and impelled by one com- mon influence. Modern philosophy has taught us to be- lieve, that, when the great Author of nature began the work of creation, he chose to operate by second causes; and that, suspend- ing the constant exertion of his power, he endued matter with a quality, by which the universal economy of nature might be con- A HISTORY OF tinued without his immediate assistance. This quality is called attraction ; a sort of approximating influence, which all bodies, whether terrestrial or celestial, are found to possess; and which in all increases as the quantity of matter in each increases. The sun, by far the greatest body in our system, is, of consequence, possessed of much the great- est share of this attracting power ; and all the planets, of which our earth is one, are, of j course, entirely subject to its superior in- fluence. Were this power, therefore, left uncontrolled by any other, the sun must quickly have attracted all the bodies of our celestial system to itself; but it is equally counteracted by another power of equal ef- ficacy; namely, a progressive force, which each planet received when it was impelled forward by the divine Architect, upon its first formation. The heavenly bodies of our sys- tem being thus acted upon by two opposing powers ; namely, by that of attraction, which draws them towards the sun; and that of impulsion, which drives them straight forward into the great void of space ; they pursue a track between these contrary directions ; and each, like a stone whirled about in a sling, obeying two opposite forces, circulates round its great centre of heat and motion. In this manner, therefore, is the harmony of our planetary system preserved. The sun, in the midst, gives heat, and light, and cir- cular motion, to the planets which surround it : Mercury, Venus, the Earth, Mars. Jupiter, Saturn, and Herschel, or the Georgium Sidus, perform their constant circuits at different distances, each taking up a time to complete its revolutions proportioned to the greatness of the circle which it is to describe. The lesser planets also, which are attendants upon some of the greater, are subject to the same laws ; they circulate with the same exactness ; and are, in the same manner, influenced by their respective centres of motion. Besides those bodies which make a part of our peculiar system, and which may be said to reside within its great circumference, there are others that frequently come among us, from the most distant tracts of space, and that seem like dangerous intruders upon the beau- tiful simplicity of nature. These are Comets, whose appearance was once so terrible to mankind ; and the theory of which is so little understood at present : all we know is, that their number is much greater than that of the planets; and that, like these, they roll in orbits, in some measure obedient to solar in- fluence. Astronomers have endeavoured to calculate the returning periods of many of them; but experience has not, as yet, con- firmed the veracity of their investigations. Indeed, who can tell, when those wanderers have made their excursions into other worlds and distant systems, what obstacles may be found to oppose their progress, to accelerate their motions, or retard their return ? But what we have hitherto attempted to sketch, is but a small part of that great fabric in which the Deity has thought proper to manifest his wisdom and omnipotence. There are multitudes of other bodies, dispersed over the face of the heavens, that lie too remote for examination: these have no motion, such as the planets are found to possess, and are there- fore called fixed stars; and from their extreme brilliancy, and their immense distance, philo- sophers have been induced to suppose them to be suns, resembling that which enlivens our system. As the imagination also, once excited, is seldom content to stop, it has fur- nished each with an attendant system of pla- nets belonging to itself; and has even induced some to deplore the fate of those systems, whose imagined suns, which sometimes hap- pens, have become no longer visible. But conjectures of this kind, which no rea- soning can ascertain, nor experiment reach, are rather amusing than useful. Though we see the greatness and wisdom of the Deity in all the seeming worlds that surround us, it is our chief concern to trace him in that which we inhabit. The examination of the earth, the wonders of its contrivance, the history of its advantages, or of the seeming defects in its formation, are the proper business of the natural historian. A description of this earth, its animals, vegetables, and minerals, is the most delightful entertainment the mind can be fur- nished with, as it is the most interesting and useful. I would beg leave, therefore, to con- clude these common-place specula' it ns. with an observation which,! hope,is not entirely so. An use, hitherto not much insist vd upon, that may result from the contemplation of ce- THE EARTH. lestial magnificence, is, that it will teach us to make an allowance for the apparent irregu- larities we find below. Whenever we can examine the works of the Deity at a proper point of distance, so as to take in the whole of his design, we see nothing but uniformity, beauty, and precision. The heavens present us with a plan, which, though inexpressibly magnificent, is yet regular beyond the power of invention. Whenever, therefore, we find any apparent defects in the earth, which we are about to consider, instead of attempting to reason ourselves into an opinion that they are beautiful, it will be wiser to say, that we do not behold them at the proper point of dis- tance, and that our eye is laid too close to the objects, to take in the regularity of their con- nexion. In short, we may conclude, that God, who is regular in his GREAT productions, acts with equal uniformity in the LITTLE. CHAPTER II. A SHORT SURVEY OF THE GLOBE, FROM THE LIGHT OF ASTRONOMY AND GEOGRAPHY. ALL the sciences are in some measure linked with each other, and before the one is ended, the other begins. In a natural histo- ry, therefore, of the earth, we must begin with a short account of its situation and form, as given us by astronomers and geographers : it will be sufficient, however, upon this occa- sion, just to hint to the imagination, what they, by the most abstract reasonings, have forced upon the understanding. The earth which we inhabit is, as has been said before, one of those bodies which circulate in our solar sys- tem; it is placed at a happy middle distance from the centre ; and even seems, in this re- spect, privileged beyond all other planets that depend upon our great luminary for their support. Less distant from the sun than Her- schel, or the Georgium Sidus, Saturn, Jupiter, and Mars, and yet less parched up than Ve- nus and Mercury, that are situate too near the violence of its power, the earth seems in a peculiar manner to share the bounty of the Creator : it is not, therefore, without reason, that mankind consider themselves as the pe- culiar objects of his providence and regard. Besides that motion which the earth has round the sun, the circuit of which is per- formed in a year, it has another upon its own axle, which it performs in twenty-four hours. Thus, like a chariot-wheel, it has a compound motion; for while it goes forward on its jour- ney, it is all the while turning upon itself. From the first of these two arise the grateful vicissitude of the seasons; from the second, that of day and night. It may be also readily conceived, that a body thus wheeling in circles will most pro- bably be itself a sphere. The earth, beyond all possibility of doubt, is found to be so. Whenever its shadow happens to fall upon the moon, in an eclipse, it appears to be al- ways circular, in whatever position it is pro- jected : and it is easy to prove, that a body which in every position makes a circular sha- dow, must itself be round. The rotundity of the earth may be also proved from the meeting of two ships at sea: the topmasts of each are the first parts that are discovered by both, the under parts being hidden by the convexi- ty of the globe which rises between them. The ships, in this instance, may be resembled to two men who approach each other on the opposite sides of a hill: their heads will first be seen, and gradually as they come nearer they will come entirely into view. However, though the earth's figure is said to be spherical, we ought only to conceive it as being nearly so. It has been found in the last age to be rather flatted at both poles, so that its form is commonly resembled to that of a turnip. The cause of this swelling of the equator is ascribed to the greater rapidity of the motion with which the parts of the earth are there carried round ; and which, consequently, en- deavouring to fly off, act in opposition to cen- tral attraction. The twirling of a mop may A HISTORY OF serve as an homely illustration; which, as every one has seen, spreads and grows broad- er in the middle as it continues to be turned round. As the earth receives light and motion from the sun, so it derives much of its warmth and power of vegetation from the same beneficent source. However, the different parts of the globe participate of these advantages in very different proportions, and accordingly put on very different appearances ; a polar prospect, and a landscape at the equator, are as oppo- site in their appearances as in their situation. The polar regions, that receive the solar beams in a very oblique direction, and conti- nue for one half of the year in night, receive but few of the genial comforts which other parts of the world enjoy. Nothing can be more mournful or hideous than the picture which travellers present of those wretched regions. The ground, "which is rocky and barren, rears itself in every place in lofty mountains and in- accessible cliffs, and meets the mariner's eye at even forty leagues from shore These pre- cipices, frightful in themselves, receive an ad- ditional horror from being constantly covered with ice and snow, which daily seem to accu- mulate, and fill all the valleys with increasing desolation. The few rocks and cliffs that are bare of snow, look at a distance of a dark brown colour, and quite naked. Upon a near- er approach, however, they are found replete with many different veins of coloured stone, here and there spread over with a little earth, and a scanty portion of grass and heath. The internal parts of the country are still more de- solate and deterring. In wandering through these solitudes, some plains appear covered with ice, that, at first glance, seem to promise the traveller an easy journey. 6 But these are even more formidable and more unpassable than the mountains themselves, being cleft with dreadful chasms, and every where abounding with pits that threaten certain de- struction. The seas that surround these in- hospitable coasts are still more astonishing, being covered with flakes of floating ice, that spread like extensive fields, or that rise out of the water like enormous mountains. These, * Crantz's History of Greenland, p. 3. "Ibid. p. 22. 'Ibid. p. 27. which are composed of materials as clear and transparent as glass, c assume many strange and fantastic appearances. Some of them look like churches or castles, with pointed turrets ; some like ships in full sail ; and people have often given themselves the fruitless toil to at- tempt piloting the imaginary vessels into har- bour. There are still others that appear like large islands, with plains, valleys, and hills, which often rear their heads two hundred yards above the level of the sea ; and although the height of these be amazing, yet their depth beneath is still more so; some of them being found to sink three hundred fathom under water. The earth presents a very different appear- ance at the equator, where the sun-beams, darting directly downwards, burn up the light- er soils into extensive sandy deserts, or quick- en all the moister tracts with incredible vege- tation. In these regions, almost all the same inconveniences are felt from the proximity of the sun, that in the former were endured from its absence The deserts are entirely barren, except where they are found to produce ser- pents, and that in such quantities, that some extensive plains seem almost entirely covered with them. u It not unfrequently happens also, that this dry soil, which is so parched and comminu- ted by the force of the sun, rises with the smallest breeze of wind ; and the sands being composed of parts almost as small as those of water, they assume a similar appearance, roll- ing onward in waves like those of a troubled sea, and overwhelming all they meet with in- evitable destruction. On the other hand, those tracts which are fertile, teem with ve- getation even to a noxious degree. The grass rises to such a height as often to require burn- ing ; the forests are impassable from under- woods, and so matted above, that even the sun, fierce as it is, can seldom penetrate.* These are so thick as scarcely to be extirpa- ted ; for the tops being so bound together by the climbing plants that grow round them, though an hundred should be cut at the bot- tom, yet no one would fall, as they mutually support each other. In these dark and tan- d Adanson's Description of Senegal. e Limuri Amienit. vol. vi. p. 67- THE EARTH. gled forests, beasts of various kinds, insects in astonishing abundance, and serpents of sur- prising magnitude, find a quiet retreat from man, and are seldom disturbed except by each other. In this manner the extremes of our globe seem equally unfitted for the comforts and con- veniences of life : and although the imagina- tion may find an awful pleasure in contempla- ting the frightful precipices of Greenland, or the luxurious verdure of Africa, yet true hap- piness can only be found in the more moder- ate climates, where the gifts of nature may be enjoyed, without incurring danger in ob- taining them. It is in the temperate zone, therefore, that all the arts of improving nature, and refining upon happiness, have been invented : and this part of the earth is, more properly speaking, the theatre of natural history. Although there be millions of animals and vegetables in the unexplored forests under the line, yet most of these may for ever continue unknown, as cu- riosity is there repressed by surrounding dan- ger. But it is otherwise in these delightful regions which we inhabit, and where this art has had its beginning. Among us there is scarce a shrub, a flower, or an insect, without its particular history; scarce a plant that could be useful, which has not been propagated; nor a weed that could be noxious, which has not been pointed out. CHAPTER III. A VIEW OF THE SURFACE OF THE EARTH. WHEN we take a slight survey of the sur- face of our globe, a thousand objects offer themselves, which, though long known, yet still demand our curiosity. The most obvious beauty that every where strikes the eye is the verdant covering of the earth, which is form- ed by an happy mixture of herbs and trees of various magnitudes and uses. It has been of- ten remarked, that no colour refreshes the sight so much as green : and it may be added, as a further proof of the assertion, that the in- habitants of those places where the fields are continually white with snow, generally be- come blind long before the usual course of nature. This advantage, which arises from the ver- dure of the fields, is not a little improved by their agreeable inequalities. There are scarcely two natural landscapes that offer prospects entirely resembling each other; their risings and depressions, their hills and valleys, are never entirely the same, but al- ways offer something new to entertain and refresh the imagination. But to increase the beauties of the face of nature, the landscape is enlivened by springs and lakes, and intersected by rivulets. These lend a brightness to the prospect ; give mo- tion and coolness to the air ; and, what is much more important, furnish health and sub- sistence to animated nature. Such are the most obvious and tranquil ob- jects that every where offer : but there are objects of a more awful and magnificent kind ; the Mountain rising above the clouds, and topt with snow; the River pouring down its sides, increasing as it runs, and losing itself, at last, in the ocean ; the Ocean spreading its immense sheet of waters over one half of the globe, swelling and subsiding at well known intervals, and forming a communication be- tween the most distant parts of the earth. If we leave those objects that seem to be natural to our earth, and keep the same con- stant tenor, we are presented with the great irregularities of nature: the burning moun- tain; the abrupt precipice; the unfathoma- ble cavern ; the headlong cataract ; and the rapid whirlpool. If we carry our curiosity a little further, 6 A HISTORY OF and descend to the objects immediately be- low the surface of the globe, we shall there find wonders still as amazing. We first per- ceive the earth for the most part lying in re- gular beds or layers, every bed growing thick- er in proportion as it lies deeper, and its con- tents more compact and heavy. We shall find, almost wherever we make our subterra- nean inquiry, an amazing number of shells that once belonged to aquatic animals. Here and there, at a distance from the sea, beds of oyster-shells, several yards thick, and many miles over; sometimes testaceous substances of various kinds on the tops of mountains, and often in the heart of the hardest marble. These, which are dug up by the peasants in every country, are regarded with little curi- osity ; for being so very common, they are considered as substances entirely terrene. But it is otherwise with the inquirer after na- ture, who finds them, not only in shape but in substance, every way resembling those that are found in the sea; and he, therefore, is at a loss to account for their removal. Yet not one part of nature alone, but all her productions and varieties, become the ob- ject of the speculative man's inquiry : he takes different views of nature from the inattentive spectator; and scarcely an appearance, how common soever, but affords matter for his contemplation : he inquires how and why the surface of the earth has those risings and de- pressions which most men call natural ; he demands in what manner the mountains were formed, and in what consists their uses ; he asks from whence springs arise, and how ri- vers flow round the convexity of the globe ; he enters into an examination of the ebbings and flowings, and the other wonders, of the deep ; he acquaints himself with the irregularities of nature, and endeavours to investigate their causes ; by which, at least, he will become better versed in their history. The internal structure of the globe becomes an object of his curiosity ; and, although his inquiries can fathom but a very little way, yet, if possessed with a spirit of theory, his imagination will supply the rest. He will endeavour to ac- count for the situation of the marine fossils Buffon, Woodward. Burnet, Whiston, Kircher, Bour- quat, Leibnitz, Steno, Ray, &c. that are found in the earth, and for the ap- pearance of the different beds of which it is composed. These have been the inquiries that have splendidly employed many of the philosophers of the last and present age, and, to a certain degree, they must be serviceable. But the worst of it is, that, as speculations amuse the writer more than facts, they may be often carried to an extravagant length ; and that time may be spent in reasoning upon nature, which might be more usefully em- ployed in writing her history. Too much speculation in natural history is certainly wrong; but there is a defect of an opposite nature that does much more preju- dice ; namely, that of silencing all inquiry, by alleging the benefits we receive from a thing, instead of investigating the cause of its pro- duction. If I inquire how a mountain came to be formed ; such a reasoner, enumerating its benefits, answers, because God knew it would be useful. If I demand the cause of an earth- quake, he finds some good produced by it, and alleges that as the cause of its explosion. Thus such an inquirer has constantly some ready reason for every appearance in nature, which serves to swell his periods, and give splendour to his declamation ; every thing about him is, on some account or other, decla- red to be good ; and he thinks it presumption to scrutinize into its defects, or to endeavour to imagine how it might be better. Such wri- ters, and there are many such, add very little to the advancement of knowledge. It is finely remarked by Bacon, that the investigation of final causes" is a barren study ; and, like a virgin dedicated to the Deity, brings forth nothing. In fact, those men who want to com- pel every appearance and every irregularity m nature into our service, and expatiate on their benefits, combat that very moralitj which they would seem to promote. God has permitted thousands of natural evils to exist in the world, because it is by their inter- vention that man is capable of moral evil; and he has permitted that we should be sub- ject to moral evil, that we might do something to deserve eternal happiness, by showing that we had rectitude to avoid it. b Investigatio causarum finalium sterifis est, et veluti virgo Deo dedicata, nil parit. THE EARTH. CHAPTER IV. A REVIEW OF THE DIFFERENT THEORIES OF THE EARTH. HUMAN invention has been exercised for several ages to account for the various irre- gularities of the earth. While those philo- sophers, mentioned in the last chapter, see nothing but beauty, symmetry, and order; there are others, who look upon the gloomy side of nature, enlarge on its defects, and seem to consider the earth, on which they tread, as one scene of extensive desolation." Beneath its surface they observe minerals and waters confusedly jumbled together; its different beds of earth irregularly lying upon each other; mountains rising from places that once were level; b and hills sinking into val- leys; whole regions swallowed by the sea, and others again rising out of its bosom. All these they suppose to be but a few of the changes that have been wrought in our globe; and they send out the imagination to describe its primeval state of beauty. Of those who have written theories de- scribing the manner of the original formation of the earth, or accounting for its present ap- pearances, the most celebrated are Burnet, Whiston, Woodward, and Buffbn. As specu- lation is endless, so it is not to be wondered that all these differ from each other, and give opposite accounts of the several changes, which they suppose our earth to have under- gone. As the systems of each have had their admirers, it is, in some measure, incumbent upon the natural historian to be acquainted, at least, with their outlines ; and, indeed, to know what others have even dreamed in mat- ters of science, is very useful, as it may often prevent us from indulging similar delusions ourselves, which we should never have adopt- ed, but because we take them to be wholly our own. However, as entering into a detail of these theories is rather furnishing a history of opinions than things, I will endeavour to be as concise as I can. The first who formed this amusement of earth-making into system, was the celebrated Buffon's Second Discourse. NO. 2. Thomas Burnet, a man of polite learning and rapid imagination. His Sacred Theory, as he calls it, describing the changes which the earth has undergone, or shall hereafter un- dergo, is well known for the warmth with which it is imagined, and the weakness with which it is reasoned; for the elegance of its- style, and the meanness of its philosophy. " The earth," says he, " before the deluge, was very differently formed from what it is at present : it was at first a fluid mass ; a chaos composed of various substances, differing both in density and figure : those which were most heavy sunk to the centre, and formed in the middle of our globe a hard solid body ; those of a lighter nature remained next ; and the waters, which were lighter still, swam upon its surface, and covered the earth on every side. The air, and all those fluids which were lighter than water, floated upon this also ; and in the same manner encompassed the globe ; so that between the surrounding body of wa- ters, and the circumambient air, there was formed a coat of oil, and other unctuous sub- stances, lighter than water. However, as the air was still extremely impure, and must have carried up with it many of those earthy parti- cles with which itoncewas intimately blended, it soon began to defecate, and to depose these particles upon the oily surface already men- tioned, which soon uniting, the earth and oil formed that crust, which soon became an ha- bitable surface, giving life to vegetation, and dwelling to animals. " This imaginary antediluvian abode was very different from what we see it at present. The earth was light and rich ; and formed of a substance entirely adapted to the feeble state of incipient vegetation ; it was an uni- form plain, every where covered with ver- dure ; without mountains, without seas, or the smallest inequalities. It had no difference of seasons, for its equator was in the plane of the ecliptic, or,in other words, it turned d : .rect- b Senec. Qua;st. lib. vi. cap. 21 D 8 A HISTORY OF ly opposite to the sun, so that it enjoyed one perpetual and luxuriant spring. However, this delightful face of nature did not long continue in the same state ; for, after a time, it began to crack and open in fissures; a circumstance which always succeeds when the sun exhales the moisture from rich or marshy situations. The crimes of mankind had been for some time preparing to draw down the wrath of Heaven; and they, at length, induced the Deity to defer repairing these breaches in na- ture. Thus the chasms of the earth every day became wider, and, at length, they pene- trated to the great abyss of waters ; and the whole earth, in a manner, fell in. Then en- sued a total disorder in the uniform beauty of the first creation, the terrene surface of the globe being broken down: as it sunk the wa- ters gushed out in its place ; the deluge be- came universal; all mankind, except eight persons, were destroyed, and their posterity condemned to toil upon the ruins of desolated nature." It only remains to mention the manner in which he relieves the earth from this univer- sal wreck, which would seem to be as difficult as even its first formation: "These great mas- ses of earth falling into the abj'ss, drew down with them vast quantities also of air ; and, by dashing against each other, and breaking into small parts by the repeated violence of the shock, they, at length, left between them large cavities, filled with nothing but air. These cavities naturally offered a bed to receive the influent waters; and in proportion as they filled, the face of the earth became once more visible. The higher parts of its broken sur- face, now become the tops of mountains, were the first that appeared ; the plains soon after came forward, and, at length, the whole globe was delivered from the waters, except the pla- ces in the lowest situations ; so that the ocean and the seas are still a part of the ancient abyss, that have not had a place to return. Islands and rocks are fragments of the earth's former crust ; kingdoms and continents are larger masses of its broken substance; and all the^ inequalities that are to be found on the surface of the present earth, are owing to the accidental confusion into which both earth and waters were then thrown.'' The next theorist was Woodward, who, in his Essay towards a Natural History of the Earth, which was only designed to precede a greater work, has endeavoured to give a more rational account of its appearances ; and was, in fact, much better furnished for such an un- dertaking than any of his predecessors, being one of the most assiduous naturalists of his time. His little book, therefore, contains many important facts, relative to natural history, although his system may be weak and ground- less. He begins by asserting that all terrene sub- stances are disposed in beds of various na- tures, lying horizontally one over the other, somewhat like the coats of an onion ; that they are replete with shells, and other produc- tions of the sea ; these shells being found in the deepest cavities, and on the tops of the highest mountains. From these observations, which are warranted by experience, he pro- ceeds to observe, that these shells and extra- neous fossils are not productions of the earth, but are all actual remains of those animals which they are known to resemble ; that all the beds of the earth lie under each other, in the order of their specific gravity ; and that they are disposed as if they had been left there by subsiding waters. All these assertions he affirms with much earnestness, although daily experience contradicts him in some of them; particularly we find layers of stone often over the lightest soils, and the softest earth under the hardest bodies. However, having taken it for granted, that all the layers of the earth are found in the order of their specific gravi- ty, the lightest at the top, and the heaviest next the centre, he consequently asserts, and it will not improbably follow, that all the sub- stances of which the earth is composed were once in an actual state of dissolution. This universal dissolution he takes to have hap- pened at the time of the flood. He supposes, that at that time a body of water, which was then in the centre of the earth, uniting with that which was found on the surface, so far separated the terrene parts as to mix all to- gether in one fluid mass; the contents of which afterwards sinking according to their respective gravities, produced the present ap- pearances of the earth. Being aware, how- ever, of an objection, that fossil substances are not found dissolved, he exempts ihein from THE EARTH this universal dissolution, and, for that pur- pose, endeavours to show that the parts of animals have a stronger cohesion than those o( minerals ; and that, while even the hardest rocks may be dissolved, bones and shells may still continue entire. So much for Woodward: but of all the sys- tems which were published respecting the earth's formation, that of Whiston was most applauded, and most opposed. Nor need we wonder: for being supported with all the pa- rade of deep calculation, it awed the igno- rant, 'and produced the approbation of such as would be thought otherwise ; as it implied a knowledge of abstruse learning, to be even thought capable of comprehending what the writer aimed at. In fact, it is not easy to divest this theory of its mathematical garb : but those who have had leisure, have found the result of our philosopher's reasoning to be thus: He supposes the earth to have been ori- ginally a comet; and he considers the history of the creation, as given us in scripture, to have its commencement just when it was, by the hand of the Creator, more regularly placed as a planet in our solar system. Before that time he supposes it to have been a globe without beauty or proportion ; a world in disorder ; subject to all the vicissitudes which comets endure ; some of which have been found, at different times, a thousand times hotter than melted iron; at others, a thousand times colder than ice. These alterations of heat and cold, continually melting and freezing the surface of the earth, he supposes to have pro- duced, to a certain depth, a chaos entirely resembling that described by the poets, sur- rounding the solid contents of the earth, which still continued unchanged in the midst, making a great burning globe of more than two thou- sand leagues in diameter. This surrounding chaos, however, was far from being solid : he resembles it to a dense though fluid atmos- phere, composed of substances mingled, agi- tated, and shocked against each other; and in this disorder he describes the earth to have been just at the eve of creation. But upon its orbit being then changed, when it was more regularly wheeled round the sun, every thing took its proper place ; every part of the surrounding fluid then fell into a situa- tion, in proportion as it was light or heavy. The middle, or central part, which always re- mained unchanged, still continued so, retain- ing a part of that heat which it received in its primeval approaches towards the sun ; which neat, he calculates, may continue for about six thousand years. Next to this fell the hea- vier parts of the chaotic atmosphere, which serve to sustain the lighter: but as in descend- ing they could not entirely be separated from many watery parts, with which they were intimately mixed, they drew down a part of these also with them; and these could not mount again after the surface of the earth was consolidated : they, therefore, surrounded the heavy first-descending parts in the same man- ner as these surround the central globe. Thus the entire body of the earth is composed in- ternally of a great burning globe : next which is placed a heavy terrene substance, that encompasses it ; round which also is circum- fused a body of water. Upon this body of water, the crust of earth, which we inhabit, is placed: so that, according to him, the globe is compo- sed of a number of coats, or shells, one within the other, all of different densities. The body of the earth being thus formed, the air, which is the lightest substance of all, surrounded its surface ; and the beams of the sun, darting through, produced that light which, we are told, hrst obeyed the Creator's command. The whole economy of the creation being thus adjusted, it only remained to account for the risings and depressions on the surface of the earth, with the other seeming irregulari- ties of its present appearance. The hills and valleys are considered by him as formed by their pressing upon the internal fluid, which sustains the outward shell of earth, with great- er or less weight : those parts of the earth which are heaviest sink into the subjacent fluid more deeply, and become valleys; those that are lightest, rise higher upon the earth's surface, and are called mountains. Such was the face of nature before the de- luge : the earth was then more fertile and po- pulous than it is at present ; the life of man and animals was extended to ten times its pre- sent duration; and all these advantages arose from the superior heat of the central globe, which ever since has been cooling. As its heat was then in full power, the genial prin- ciple was also much greater than at present ; 10 A HISTORY OF vegetation and animal increase were carried on with more vigour ; and all nature seemed teeming with the seeds of life. But these phy- sical advantages were only productive of mo- ral evil; the warmth which invigorated the body increased the passions and appetites of the mind ; and, as man became more power- ful, he grew less innocent. It was found necessary to punish this depravity ; and all living creatures were overwhelmed by the deluge in universal destruction. This deluge, which simple believers are willing to ascribe to a miracle, philosophers have long been desirous to account for by na- tural causes ; they have proved that the earth could never supply from any reservoir towards its centre, nor the atmosphere by any dis- charge from above, such a quantity of water as would cover the surface of the globe to a certain depth over the tops of our highest mountains. Where, therefore, was all this wa- ter to be found ? Whiston has found enough, and more than a sufficiency, in the tail of a comet ; for he seems to allot comets a very active part in the great operations of nature. He calculates, with great seeming preci- sion, the year, the month, and the day of the week, on which this comet (which has paid the earth some visits since, though at a kind- er distance) involved our globe in its tail. The tail he supposed to be a vaporous fluid substance, exhaled from the body of the comet by the extreme heat of the sun, and increasing in proportion at it approached that great lu- minary. It was in this that our globe was in- volved at the time of the deluge ; and, as the earth still acted by its natural attraction, it drew to itself all the watery vapours which were in the comet's tail; and the internal wa- ters being also at the same time let loose, in a very short space the tops of the highest mountains were laid under the deep. The punishment of the deluge being thus completed, and all the guilty destroyed, the earth, which had been broken by the eruption of the internal waters, was also enlarged by it ; so that, upon the comet's recess, there was found room sufficient in the internal abyss for the recess of the superfluous waters ; whither they all retired, and left the earth uncovered, but in some respects changed, particularly in its figure, which, from being round, was now become oblate. In this universal wreck of na- ture, Noah survived, by a variety of happy causes, to re-people the earth, and to give birth to a race of men slow in believing ill- imagined theories of the earth. After so many theories of th-i earth which have been published, applauded, answered, and forgotten, Mr. Buffbn ventured to add one more to the number. This philosopher was, in every respect, better qualified than any of his predecessors for such an attempt, being furnished with more materials, having abright- er imagination to find new proofs, and a=better style to clothe them in. However, if one so ill qualified as I am may judge, this seems the weakest part of his admirable work ; and I could wish that he had been content with giving us facts instead of systems; that, in- stead of being a reasoner, he had contented himself with being merely an historian He begins his system by making a distinc- tion between the first part of it and the last ; the one being founded only on conjecture, the other depending entirely upon actual obser- vation. The latter part of his theory may, therefore, be true, though the former should be found erroneous. " The planets," says he, " and the earth among the number, might have been formerly (he only offers this as conjecture) a part of the body of the sun, and adherent to its sub- stance. In this situation, a comet falling in upon that great body, might have given it such a shock, and so shaken its whole frame, that some of its particles might have been driven off like streaming sparkles from red- hot iron ; and each of these streams of fire, small as they were in comparison of the sun, might have been large enough to have made an earth as great, nay, many times greater, than ours. So that in this manner the planets, together with the globe which we inhabit, might have been driven off from the body of the sun by an impulsive force : in this man- ner also they would continue to recede from it for ever, were they not drawn back by its superior power of attraction ; and thus, by the combination of the two motions, they are wheeled round in circles. " Being in this manner detached at a dis- tance from the body of the sun, the planets, from having been at first globes of liquid fire, THE EARTH. gradually became cool. The earth also, hav- ing been impelled obliquely forward, received a rotatory motion upon its axis at the very in- stant of its formation ; and this motion being greatest at the equator, the parts there acting against the force of gravity, they must have swollen out, and given the earth an oblate or flatted figure. " As to its internal substance, our globe, having once belonged to the sun, it continues to be an uniform mass of melted matter, very probably vitrified in its primeval fusion. But its surface is very differently composed. Hav- ing been in the beginning heated to a degree equal to, if not greater, than what comets are found to sustain ; like them it had an atmos- phere of vapours floating round it, and which, cooling by degrees, condensed and subsided upon its surface. These vapours formed, ac- cording to their different densities, the earth, the water, and the air ; the heavier parts fall- ing first, and the lighter remaining still sus- pended." Thus far our philosopher is, at least, as much a system-maker as Whiston or Burnet ; and, indeed, he fights his way with great per- severance and ingenuity, through a thousand objections that naturally arise. Having, at last, got upon the earth, he supposes himself on firmer ground, and goes forward with great- er security. Turning his attention to the pre- sent appearance of things upon this globe, he pronounces from the view, that the whole earth was at first under water. This water he supposes to have been the lighter parts of its former evaporation, which, while the earthy particles sunk downwards by their na- tural gravity, floated on the surface, and co- vered it for a considerable space of time. " The surface of the earth," says he," "must have been in the beginning much less solid than it is at present ; and, consequently, the same causes which at this day produce but very slight changes, must then, upon so com- plying a substance, have had very considera- ble effects. We have no reason to doubt but that it was then covered with the waters of the sea; and that those waters were above the tops of our highest mountains: since, even in such elevated situations, we find shells and Theorie de la Terre, vol. i. p. 111. other marine productions in very great abun- dance. It appears also that the sea continued for a considerable time upon the face of the earth : for as these layers of shells are found so very frequent at such great depths, and in such prodigious quantities, it seems impossible for such numbers to have been supported all alive at one time; so that they must have been brought there by successive depositions. These shells also are found in the bodies of the hardest rocks, where they could not have been deposited, all at once, at the time of the deluge, or at any such instant revolution ; since that would be to suppose, that all the rocks in which they are found, were, at that instant, in a state of dissolution, which would be absurd to assert. The sea, therefore, de- posited them wheresoever they are now to be found, and that by slow and successive de- grees. " It will appear also, that the sea covered the whole earth, from the appearance of its layers, which lying regularly one above the other, seem all to resemble the sediment form- ed at different times by the ocean. Hence, by the irregular force of its waves, and its currents driving the bottom into sand- banks, mountains must have been gradually formed within this universal covering of waters; and these successively raising their heads above its surface, must, in time, have formed the highest ridges of mountains upon land, together with continents, islands, and low grounds, all in their turns. This opinion will receive additional weight by considering, that in those parts of the earth where the pow- er of the ocean is greatest, the inequalities on the surface of the earth are highest. The ocean's power is greatest at the equator, where its winds and tides are most constant ; and, in fact, the mountains at the equator are found to be higher than in any other part of the world. The sea, therefore, has produced the principal changes in our earth : rivers, volca- noes, earthquakes, storms, and rain, having made but slight alterations, and only such as have affected the globe to very inconsidera- ble depths." This is but a very slight sketch of Mr. Buffon's theory of the earth ; a theory which he has much more powerfully supported, than happily invented ; and it would be needless to E 12 A HISTORY OF take up the reader's time from the pursuit of | most compact and ponderous substances truth in the discussion of plausibilities. In fact, a thousand questions might be asked this most ingenious philosopher, which he would not find it easy to answer ; but such is the lot of humanity, that a single Goth can in one day destroy the fabric which Ctesars were em- ployed an age in erecting. We might ask, How mountains, which are composed of the should be the first whose parts the sea began to remove ? We might ask, How fossil-wood is found deeper even than shells ? which ar- gues, that trees grew upon the places he sup- poses once to have been covered with the ocean. But we hope this excellent man is better em- ployed than to think of gratifying the petulance of incredulity, by answering endless objections. CHAPTER V. OF FOSSIL-SHELLS, AND OTHER EXTRANEOUS FOSSILS. WE may affirm of Mr. Buffon, that which has been said of the chymists of old ; though he may have failed in attaining his principal aim, of establishing a theory, yet he has brought together such a multitude of facts relative to the history of the earth, and the nature of its fossil productions, that curiosity finds ample compensation, even while it feels the want of conviction. Before, therefore, I enter upon the descrip- tion of those parts of the earth which seem more naturally to fall within the subject, it will not be improper to give a short history of those animal productions that are found in such quantities, either upon its surface, or at different depths below it. They demand our curiosity; and, indeed, there is nothing in na- tural history that has afforded more scope for doubt, conjecture, and speculation. Whatever depths of the earth we examine, or at what- ever distance within land we seek, we most commonly find a number of fossil-shells, which being compared with others from the sea, of known kinds, are found to be exactly of a similar shape and nature." They are found at the very bottom of quarries and mines, in the retired and inmost parts of the most firm and solid rocks, upon the tops of even the highest hills and mountains, as well as in the valleys and plains ; and this not in one country alone, but in all places where there is any digging for marble, chalk, or any other terrestrial mat- " Woodward's Essay towards a Natural History, p 3,6. ters, that are so compact as to fence off the external injuries of the air, and thus preserve these shells from decay. These marine substances, so commonly dif- fused, and so generally to be met with, were for a long time considered by philosophers as productions, not of the sea, but of the earth, " As we find that spars," said they, " always shoot into peculiar shapes, so these seeming snails, cockles, and mussel-shells, are only sportive forms that nature assumes amongst others of its mineral varieties: they have the shape of fish, indeed, but they have always been terrestrial substances.'" 1 With this plausible solution mankind were for a long time content : but upon closer in- quiry, they were obliged to alter their opinion. It was found that these shells had in every re- spect the properties of animal, and not of mi- neral nature. They were found exactly of the same weight with their fellow shells upon shore. They answered all the chymical trials in the same manner as sea-shells do. Their parts, when dissolved, had the same appearr ance to view, the same smell and taste. They had the same effects in medicine, when in- wardly administered ; and, in a word, were so exactly conformable to marine bodies, that they had all the accidental concretions growing to them, (such as pearls, corals, and smaller shells,) which are found in shells just gathered on the shore. They were, there- b Lowthorp's Abridgment, Phil. Trans, vol. ii. p. 426. THE EARTH. 13 fore, from these considerations, given back to the sea; but the wonder was, how to ac- count for their coining so far from their own natural element upon land." As this naturally gave rise to many conjec- tures, it is not to be wondered that some among them have been very extraordinary. An Italian, quoted by Mr. Buffbn, supposes them to have been deposited in the earth at the time of the crusades, by the pilgrims who returned from Jerusalem; who gathering them upon the sea-shore, in their return carried them to their different places of habitation. But this conji-cturer seems to have but a very inadequate idea of their numbers. At Tou- raine, in France, more than a hundred miles from the sea, there is a plain of about nine leagues long, and as many broad, whence the peasants of the country supply themselves with marl for manuring their lands. They seldom dig deeper than twenty feet ; and the whole plain is composed of the same mate- rials, which are shells of various kinds, with- out the smallest portion of earth between them. Here then is a large space, in which are deposited millions of tons of shells, that pilgrims could not have collected, though their whole employment had been nothing else. England is furnished with its beds, which, though not quite so extensive, yet are equally wonderful. " Near Reading, in Berkshire, for many succeeding generations, a continued body of oyster-shells has been found through the whole circumference of five or six acres of ground. The foundation of these shells is a hard rocky chalk ; and above this chalk, the oyster-shells lie in a bed of green sand, upon a level,as nigh as can possibly be judged, and about two feet thickness." b These shells are in their natural state, but they were found also petrified, and almost in equal abundance 8 in all the Alpine rocks, in the Pyrenees, on the hills of France, England, and Flanders. Even in all quarries from whence marble is dug, if the rocks be split perpendicularly downwards, petrified shells and other marine substances will be plainly discerned. " About a quarter of a mile from the river Medway, in the county of Kent, after the Woodward, p. 43. * Phil. Trans, vol. ii. p. 427- c Button, vol. i. p. 40". taking off" the coping of a piece of ground there, the workmen came to a blue marble, which continued for three feet and a half deep, or more, and then beneath appeared a hard iloor, or pavement, composed of petrified shells crowded closely together. This layer was about an inch deep, and several yards over; and it could be walked upon as upon a beach. These stones, of which it was com- posed, (the describer supposes them to have always been stones,) were either wreathed as snails, or bivalvular like cockles. The wreathed kinds were about the size of a hazel-nut, and were filled with a stony sub- stance of the colour of marl ; and they them- selves, also, till they were washed, were of the same colour; but when cleaned, they ap- peared of the colour of bezoar, and of the same polish. After boiling in w ater they be- came whitish, and left a chalkiness upon the fingers."" In several parts of Asia and Africa, travel- lers have observed these shells in great abun- dance. In the mountains of Castravan, which lie above the city Barut, they quarry out a white stone, every part of which contains pe- trified fishes in great numbers, and of sur- prising diversity. They also seem to continue in such preservation, that their fins, scales, and all the minutest distinctions of their make, can be perfectly discerned." From all these instances we may conclude, that fossils are very numerous ; and, indeed, independent of their situation, they afford no small entertainment to observe them as pre- served in the cabinets of the curious. The varieties of their kinds are astonishing. Most of the sea-shells which are known, and many others to which we are entirely strangers, are to be seen either in their natural state, or in various degrees of petrifaction/ In the place of some we have mere spar, or stone, exactly expressing all the lineaments of animals, as having been wholly formed from them. For it has happened, that the shells dissolving by very slow degrees, and the matter having nicely and exactly filled all the cavities within, this matter, after the shells have perished, has preserved exactly and regularly the whole rt Phil.

Of these there are various kinds found in our pits; many of them resembling those of our own shores; and many others that are only to be found on the coasts of other countries. There are some shells resembling those that are never strand- ed upon otir coasts;" but always remain in the deep: b and many more there are which we can assimulate with no shells that are known amongst us. But we find not only shells in our pits, but also fishes and corals in great abundance; together with almost every sort of marine production. It is extraordinary enough, however, that the common red coral, though so very fre- quent at sea, is scarcely seen in the fossil world; nor is there any account of its having ever been met with. But to compensate for this, there are all the kinds of the white coral now known, and many other kinds of that substance with which we are unacquainted. Of animals there are various parts : the ver- tebrae of whales, and the mouths of lesser fishes; these, with teeth also of various kinds, are found in the cabinets of the curious; where they receive long Greek names, which it is neither the intention nor the province of this work to enumerate. Indeed, few readers would think themselves much improved, should I proceed with enumerating the va- rious classes of the Conicthyodontes, Poly- leptoginglimi, or the Orthoceratites. These names, which mean no great matter when they are explained, may serve to guide in the furnishing a cabinet; but they are of very little service in furnishing the page of instruc- tive history. From all these instances we see in what abundance petrifactions are to be found; and, indeed, Mr. Buffbn, to whose accounts we have added some, has not been sparing in the variety of his quotations, concerning the places where they are mostly to be found. However, I am surprised that he should have omitted the mention of one, which, in some measure, more than any of the rest, would have served to strengthen his theory. We are informed, by almost every traveller' that has described the pyramids of Egypt, that one of them is entirely built of a kind of free-stone, * Littorales. b Pelagii. in which these petrified shells are found in great abundance. This being the case, it may be conjectured, as we have accounts of these pyramids among the earliest records of mankind, and of their being built so long before the age of Herodotus, who lived but fifteen hundred years after the flood, that even the Egyptian priests could tell neither the time nor the cause of their erection ; I say, it may be conjectured that they were erected but a short time after the flood. It is not very likely, therefore, that the marine substances found in one of them, had time to be formed into a part of the solid stone, either during the deluge, or immediately after it ; and, con- sequently, their petrifaction must have been before that period. And this is the opinion Mr. Buffbn has so strenuously endeavoured to maintain; having given specious reasons to prove, that such shells were laid in the beds where they are now found, not only before the deluge, but even antecedent to the for- mation oi' man, at the time when the whole earth, as he supposes, was buried beneath a covering of waters. But while there are many reasons to per- suade us that these extraneous fossils have been deposited by the sea, there is one fact that will abundantly serve to convince us, that the earth was habitable, if not inhabited, before these marine substances came to be thus deposited. For we find fossil-trees, which no doubt once grew upon the earth, as deep, and as much in the body of solid rocks, as these sheila are found to be. Some of these fallen trees also have lain at least as long, if not longer, in the earth, than the shells, as they have been found sunk deep in a marly substance, composed of decayed shells, and other marine productions. Mr. Buffbn has proved, that fossil-shells could not have been deposited in such quantities all at once by the flood; and I think, from the above instance, it is pretty plain, that, howsoever they were deposited, the earth was covered with trees before their deposition ; and, con- sequently, that the sea could not have made a very permanent stay. How then shall we account for these extraordinary appearances in nature? A suspension of all assent is c Hasselquist, Sandys. THE EARTH. 15 certainly the first, although the most morti- fying conduct. For my own part, were I to offer a conjecture, (and all that has been said upon this subject is but conjecture,) instead of supposing them to be the remains of ani- mals belonging to the sea, I would consider them rather as bred in the numerous fresh- water lakes, that in primeval times covered the face of uncultivated nature. Some of these shells we know to belong to fresh wa- ters; some can be assimilated to none of the marine shells now known ;" why, therefore, may we not as well ascribe the production of all to fresh waters, where we do not find them, as we do that of the latter to the sea only, where we never find them ? We know that lakes, and lands also, have produced animals that are now no longer ex- isting ; why, therefore, might not these fossil productions be among the number? I grant that this is making a very harsh supposition ; but I cannot avoid thinking, that it is not at- tended with so many embarrassments as some of the former, and that it is much easier to believe that these shells were bred in fresh water, than that the sea had for a long time covered the tops of the highest mountains. CHAPTER VI. OF THE INTERNAL STRUCTURE OF THE EARTH. HAVING, in some measure, got free from the regions of conjecture, let us now proceed to a description of the earth as we find it by examination, and observe its internal compo- sition, as far as it has been the subject of ex- perience, or exposed to human inquiry. These inquiries, indeed, have been carried but to a very little depth below its surface, and even in that disquisition men have been conducted more by motives of avarice than of curiosity. The deepest mine, which is that at Cotteberg in Hungary, b reaches not more than three thousand feet deep; but what proportion does that bear to the depth of the terrestrial globe, down to the centre, which is above four thou- sand miles? All, therefore, that has been said of the earth, to a deeper degree, is merely fabulous or conjectural : we may sup- pose with one, that it is a globe of glass ; c with another, a sphere of heated iron; d with a third, a great mass of waters ; e and with a fourth, one dreadful volcano : f but let us at the same time show our conciousness, that all these are but suppositions. Upon examining the earth, where it has been opened to any depth, the first thing that Hill's FossUs, p. 41. b Boyle, vol. iii. p. 240. <= Buffon. Whiston. occurs, is the different layers or beds of which it is composed ; these all lying horizontally one over the other, like the leaves of a book, and each of them composed of materials that increase in weight in proportion as they lie deeper. This is, in general, the disposition of the different materials, where the earth seems to have remained unmolested ; but this order is frequently inverted ; and we cannot tell whether from its original formation, or from accidental causes. Of different sub- stances, thus disposed, the far greatest part of our globe consists, from its surface down- wards to the greatest depths we ever dig or mine. 6 The first layer, most commonly found at the surface, is that light coat of blackish mould, which is called by some garden earth. With this the earth is every where invested, unless it be washed off by rains, or removed by some other external violence. This seems to have been formed from animal and vege- table bodies decaying, and thus turning into its substance. It also serves again as a store- house, from whence animal and vegetable nature are renewed ; and thus are all vital e Burnet. f Kircher e Woodward, p. 9 A HISTORY OF blessings continued with unceasing circula- tion. This earth, however, is not to be sup- posed entirely pure, but is mixed with much stony and gravelly matter, from the layers lying immediately beneath it. It generally happens, that the soil is fertile in proportion to the quantity that this putrefied mould bears to the gravelly mixture ; and as the former predominates, so far is the vegetation upon it more luxuriant. It is this external covering that supplies man with all the true riches he enjoys. He may bring up gold and jewels from greater depths ; but they are merely the toys of a capricious being, things upon which he has placed an imaginary value, and for which fools alone part with the more substan- tial blessings of life. " It is this earth," says Pliny ," "that, like a kind mother, receives us at our birth, and sustains us when born." It is this alone, of all the elements around us, that is never found an enemy to man. The body of waters deluge him with rains, oppress him with hail, and drown him with inunda- tions. The air rushes in storms, prepares the tempest, or lights up the volcano ; but the earth,- gentle and indulgent, ever subservient to the wants of man, spreads his walks with flowers, and his table with plenty; returns with interest every good committed to her care ; and though she produces the poison, she still supplies the antidote ; though con- stantly teased more to furnish the luxuries of man than his necessities, yet, even to the last, she continues her kind indulgence, and, when life is over, she piously covers his remains in her bosom. This external and fruitful layer which co- vers the earth, is, as was said, in a state of continual change. Vegetables, which are naturally fixed and rooted to the same place, receive their adventitious nourishment from the surrounding earth and water; animals, which change from place to place, are sup- ported by these, or by each other. Both, however, having for a time enjoyed a life adapted to their nature, give back to the earth those spoils, which they had borrowed for a very short space, yet still to be quick- ened again into fresh existence. But the de- posits they make are of very dissimilar kinds, * Plinii Historia Naturalis, lib. ii. cap. 63. and the earth is very differently enriched by their continuance; those countries, that have for a long time supported men and other ani- mals, having been observed to become every day more barren ; while, on the contrary, those desolate places, in which vegetables only are abundantly produced, are known to be possessed of amazing fertility. "In regions which are uninhabited," 1 " says Mr. Buffbn, " where the forests arc not cut down, and where animals do not feed upon the plants, the bed of vegetable earth is constantly in- creasing. In all woods, and even in those Avhich are often cut, there is a layer of earth, of six or eight inches thick, which has been formed by the leaves, branches, and bark, which fall and rot upon the ground. I have frequently observed on a Roman way, which crosses Burgundy for a long extent, that there is a bed of black earth, of more than a toot thick, gathered over the stony pavement, on which several trees, of a very considerable size, are supported. This I have found to be nothing else than an earth formed by decayed leaves and branches, which have been con- verted by time into a black soil. Now, as vegetables draw much more of their nourish- ment from the air and water than they do from the earth, it must follow, that in rotting upon the ground, they must give more to the soil than they have taken from it. Hence, therefore, in woods kept a long time without cutting, the soil below increases to a con- siderable depth ; and such we actually find the soil in those American wilds, where the forests have been undisturbed for ages. But it is otherwise where men and animals have long subsisted : for as they make a conside- rable consumption of wood and plants, both for firing and other uses, they take more from the earth than they return to it ; it follows, therefore, that the bed of vegetable earth, in an inhabited country,must be always diminish- ing; and must at length resemble the eoil of Arabia Petrea, and other provinces of the East, which having been long inhabited, are now become plains of salt and sand ; the fixed salt always remaining, while the other volatile parts have flown away." If from this external surface we descend b Buifon, vol. i. p. 353. THE EARTH. 17 deeper, and view the earth cut perpendicu- larly downwards, either in the banks of great rivers, or sleepy sea-shores, or, going still deeper, if we observe it in quarries or mines, we shill find its layers regularly disposed in their proper order. We must not expect, however, to find them of the same kind or thickness in every place, as they diiler in dif- ferent soils and situations. Sometimes marl is seen to be over sand, and sometimes under it. The most common disposition is, that under the first earth is found gravel or sand, then clay or marl, then chalk or coal, marbles, ores, sands, gravels; and thus an alternation of these substances, each growing more dense as it sinks deeper. The clay, for instance, found at the depth of a hundred feet, is usually more heavy than that found not far from the surface. In a well which was dug at Amster- dam, to the depth of two hundred and thirty feet, the following substances were found in succession:" seven feet of vegetable earth, nine of turf, nine of soft clay, eight of sand, four of earth, ten of clay, four of earth, ten of sand, two of clay, four of white sand, one of soft earth, fourteen of sand, eight of clay mixed with sand, four of sea-sand mixed with shells, then a hundred and two feet of soft clay, and then thirty-one feet of sand. In a well dug at Marly, to the depth of a hundred feet, Mr. BufFon gives us a still more exact enumeration of its layers of earth. " Thirteen of a reddish gravel, two of gravel mingled with a vitrifiable sand, three of mud or slime, two of marl, four of marly stone, five of marl in dust mixed with vitrifiable sand, six of very fine vitrifiable sand, three of earthy marl, three of hard marl, one of gravel, one of eglantine, a stone of the hardness and grain of marble, one of gravelly marl, one of stony marl, one of a coarser kind of stony marl, two of a coarser kind still, one of vitrifiable sand mixed with fossil-shells, two of fine gravel, three of stony marl, one of coarse powdered marl, one of stone calcinable like marble, three of gray sand, two of white sand, one of red sand streaked with white, eight of gray sand with shells, three of very fine sand, three of a hard gray stone, four of red sand streaked Varenius, as quoted by Mr. Buffon, p. with white, three of white sand, and fifteen of reddish vitrifiable sand. In this manner the earth is every where found in beds over beds; and, what is still re markable, each of them, as far as it extends always maintains exactly the same thickness It is found also, that as we proceed to con- siderable depths, every layer grows thicker. Thus in the adduced instances we might have observed, that the last layer was fifteen feet thick, while most of the others were not above eight ; and this might have gone much deeper, for aught we can tell, as before they got through it the workmen ceased digging These layers are sometimes very extensive, and often arc found to spread over a space of some leagues in circumference. But it must not be supposed that they are uniformly continued over the whole globe without any interruption: on the contrary, they are ever, at small intervals, cracked through as it were by perpendicular fissures ; the earth resembling, in this respect, the muddy bottom of a pond, from whence the water has been dried off by the sun, and thus gaping in several chinks, which descend in a direction perpendicular to its surface. These fissures are many times found empty, but oftener closed up with adventitious sub- stances, that the rain, or some other acci- dental causes, have conveyed to fill their cavities. Their openings are not less different than their contents, some being not above half an inch wide, some a foot, and some several hundred yards asunder ; which last form those dreadful chasms that are to be found in the Alps, at the edge of which the traveller stands dreading to look down at the immeasurable gulf below. These amazing clefts are well known to such as havepassed thesemountains, where a chasm frequently presents itself se- veral hundred feet deep, and as many over, at the edge of which the way lies. It often happens also, that the road leads along the bottom, and then the spectator observes on each side frightful precipices several hundred yards above him; the sides of which corres- pond so exactly with each other, that they evidently seem torn asunder. But these chasms, to be found in the Alps, are nothing to what Ovalle tells us are to be seen in the Andes. These amazing moun- tains, in comparison of which the former are 18 A HISTORY OF but little hills, have their fissures in propor- tion to their greatness. In some places they are a mile wide, and deep in proportion ; and there are some others, that, running under ground, in extent resemble a province. Of this kind also is that cavern called El- denhole, in Derbyshire, which Dr. Plott tells us was sounded by a line of eight and twenty hundred feet, without finding the bottom, or meeting with water: and yet the mouth at the top is not above forty yards over." This im- measurable cavern runs perpendicularly down- ward ; and the sides of it seem to tally so plainly as to show that they once were united. Those who come to visit the place, generally procure stones to be thrown into its mouth ; and these are heard for several minutes, fall- ing and striking against the sides of the ca- vern, producing a sound that resembles distant thunder, dying away as the stone goes deeper. Of this kind also is that dreadful cavern described by ^Elian ; his account of which the reader may not have met with. b "In the country of the Arrian Indians, is to be seen an amazing chasm, which is called, The Gulf of Pluto. The depth and the recesses of this horrid place are as extensive as they are un- known. Neither the natives, nor the curious who visit it, are able to tell how it was first made, or to what depths it descends. The Indians continually drive thither great multi- tudes of animals, more than three thousand at a time, of different kinds, sheep, horses, and goats : and, with an absurd superstition, force them into the cavity, from whence they never return. Their several sounds, however, are heard as they descend ; the bleating of sheep, the lowing of oxen, and the neighing of horses, issuing up to the mouth of the cavern. Nor do these sounds cease, as the place is con- tinually furnished with a fresh supply." Phil. Trans, vol. ii. p. 370 There are many more of these dreadful perpendicular fissures in different parts oi the earth ; with accounts of which Kircher, GafFarellus, and others, who have given histo- ries of the wonders of the subterranean world, abundantly supply us. The generality of readers, however, will consider them with less astonishment when they are informed of their being common all over the earth; that in every field, in every quarry, these perpendi- cular fissures are to be found, either still gaping, or filled with matter that has acci- dentally closed their interstices. The inat- tentive spectator neglects the inquiry, but their being common is partly the cause that excites the philosopher's attention to them; the irregularities of nature he is often content to let pass unexamined ; but when a constant and a common appearance presents itself, every return of the object is a fresh call to his curiosity ; and the chink in the next quarry becomes as great a matter of wonder as the chasm in Eldenhole. Philosophers have long, therefore, endeavoured to find out the cause of these perpendicular fissures, which our own countrymen, Woodward and Ray, were the first that found to be so common and univer- sal. Mr. Buffbn supposes them to be cracks made by the sun, in drying up the earth, immediately after its emersion from the deep. The heat of the sun is very probably a prin- cipal cause ; but it is not right to ascribe to one only, what we find may be the result of many. Earthquakes, severe frosts, bursting waters, and storms tearing up the roots of trees, have, in our own times, produced them ; and to this variety of causes we must, at pre- sent, be content to assign those that have happened before we had opportunities for observation. b yEliani Var. Hist. lib. xvi. cap. 16. THE EARTH. 19 CHAPTER VH. OF CAVES AND SUBTERRANEOUS PASSAGES THAT SINK, BUT NOT PER- PENDICULARLY, INTO THE EARTH. IN surveying the subterranean wonders of the globe, besides those fissures that descend perpendicularly, we frequently find others that descend but a little way, and then spread themselves often to a great extent below the surface. Many of these caverns, it must be confessed, mny be the production of art and human industry; retreats made to protect the oppressed, or shelter the spoiler. The fa- mous labyrinth of Candia, for instance, is supposed to be entirely the work of art. Mr. Tournefort assures us, that it bears the im- pression of human industry, and that great pains have been bestowed upon its formation. The stone-quarry of Maastricht is evidently made by labour: carts enter at its mouth, and load within, then return, and discharge their freight into boats that lie on the brink of the river Maese. This quarry is so large, that forty thousand people may take shelter in it: and it in general serves for this purpose, when armies march that way ; becoming then an impregnable retreat to the people that live thereabout. Nothing can be more beautiful than this cavern, when lighted up with torches : for there are thousands of square pillars, in large level walks, about twenty feet high ; and all wrought with much neatness and regularity. In this vast grotto there is very little rubbish; which shows both the goodness of the stone and the carefulness of the workmen. To add to its beauty, there also are, in various parts of it, little pools of water, for the convenience of the men and cattle. It is remarkable also, that no drop- pings are seen to fall from the roof, nor are the walks any way wet under foot, except in cases of great rains, where the water gets in by the air-shafts. The salt-mines in Poland are still more spacious than these. Some of the catacombs, both in Egypt and Italy, are said to be very extensive. But no part of the world has a greater number of artificial ca- a Phil. Trans, vol. ii. p. 368. NO. 3. verns that Spain, which were made to serve as retreats to the Christians against the fury of the Moors, when the latter conquered that country. However, an account of the works of art does not properly belong to a natural history. It will be enough to observe, that though caverns be found in every country, far the greatest part of them have been fashioned by the hand of nature only. Their size is found beyond the power of man to have effected, and their forms but ill adapted to the conveniences of a human habitation. In some places, indeed, we find mankind still make use of them as houses; particularly in those countries where the climate is very se- vere;" but in general they are deserted by every race of meaner animals, except the bat : these nocttirnal solitary creatures are usually the only inhabitants ; and these only in such whose descent is sloping, or, at least, not directly perpendicular. There is scarcely a country in the world without its natural caverns; and many new ones are discovered every day. Of those in England, Oakey-hole, the Devil's-hole, and Penpark-hole, have been often described. The former, which lies on the south side of Mendip-hills, b within a mile of the town of Wells, is much resorted to by travellers. To conceive a just idea of this, we must imagine a precipice of more than a hundred yards high, on the side of a mountain which shelves away a mile above it. In this is an opening not very large, into which you enter, going along upon a rocky uneven pavement, some- times ascending, and sometimes descending. The roof of it, as you advance, grows higher; and, in some places, is fifty feet from the floor. In some places, however, it is so low, that a man must stoop to pass. It extends itself, in length, about two hundred yards: and from every part of the roof and the floor, there are formed sparry concretions of various b Phil. Traus. vol. ii. p. 368. G A HISTORY OF figures, that by strong imaginations have been likened to men, lions, and organs. At the farthest part of this cavern rises a stream of water, well stored with fish, large enough to turn a mill, and which discharges itself near the entrance. Penpark-hole, in Gloucestershire, is almost as remarkable as the former. Captain Sturmy descended into this by a rope, twenty-five fathoms perpendicular, and at the bottom found a very large vault in the shape of a horse-shoe. The floors consisted of a kind of white stone enamelled with lead ore, and the pendant rocks were glazed with spar. Walking forward on this stony pavement, for some time, he came to a great river, twenty fathoms broad, and eight fathoms deep ; and having been informed that it ebbed and flowed with the sea, he remained in this gloomy abode for five hours, to make an ex- act observation. He did not find, however, any alteration whatsoever in its appearance. But his curiosity was ill requited ; for it cost this unfortunate gentleman his life : imme- diately after his return he was seized with an unusual and violent headach, which threw him into a fever, of which he died soon after. But of all the subterranean caverns now known, the grotto of Antiparos is the most remarkable, as well for its extent as for the beauty of its sparry incrustations. This ce- lebrated cavern was first discovered by one Magni, an Italian traveller, about an hundred years ago, at Antiparos, an inconsiderable island of the Archipelago." The account he gives of it is long and inflated, but upon the whole amusing. " Having been informed," says he, " by the natives of Paros, that in the little island of Antiparos, which lies about two miles from the former, of a gigantic statue that was to be seen at the mouth of a cavern in that place, it was resolved that we (the French consul and himself) should pay it a visit. In pursuance of this resolution, after we had landed on the island, and walked about four miles through the midst of beau- tiful plains, and sloping woodlands, we at length came to a little hill, on the side of Kircher Mund. sub. 112. I have translated a part of Kircher's description, rather than Tournefort's, as the latter was written to support an hypothesis. which yawned a most horrid cavern, that with its gloom at first struck us with terror, and almost repressed curiosity. Recovering the first surprise, however, we entered boldly ; and had not proceeded above twenty paces, when the supposed statue of the giant pre- sented itself to our view. We quickly per- ceived, that what the ignorant natives had been terrified at as a giant, was nothing more than a sparry concretion, formed by the water dropping from the roof of the cave, and by degrees hardening into a figure that their fears had formed into a monster. Incited by this extraordinary appearance, we were in- duced to proceed still farther, in quest of new adventures in this subterranean abode. As we proceeded, new wonders offered them- selves; the spars formed into trees and shrubs presented a kind of petrified grove; some white, some green ; and all receding in due perspective. They struck us with the more amazement, as we knew them to be mere productions of Nature, who, hitherto in soli- tude, had, in her playful moments, dressed the scene as if for her own amusement. " But we had as yet seen but a few of the wonders of the place; and were introduced only into the portico of this amazing temple. In one corner of this half-illuminated recess, there appeared an opening of about three feet wide, which seemed to lead to a place totally dark, and that, one of the natives as- sured us, contained nothing more than a reser- voir of water. Upon this we tried, by throwing down some stones, which rumbling along the sides of the descent for some time, the sound seemed at last quashed in a bed of water. In order, however, to be more certain, we sent in a Levantine mariner, who, by the promise of a good reward, with a flambeaux in his hand, ventured into this narrow aperture. After continuing within it for about a quarter of an hour, he returned, carrying some beau- tiful pieces of white spar in his hand, which art could neither imitate nor equal. Upon being informed by him that the place was full of these beautiful incrustations,! ventured in once more with him for about fifty paces, anxiously and cautiously descending by a steep and dangerous way. Finding, however, that we came to a precipice which led into a spacious amphitheatre, if I may so call it. THE EARTH. -21 still deeper than any other part, we returned, and being provided with a ladder, flambeaux, and other things to expedite our descent, our whole company, man by man, ventured into the same opening, and descending one after another, we at last saw ourselves alto- gether in the most magnificent part of the cavern. " Our candles being now all lighted up, and the whole place completely illuminated, never could the eye be presented with a more glit- tering, or a more magnificent scene. The roof all hung with solid icicles, transparent as glass, yet solid as marble. The eye could scarcely reach the lofty and noble ceiling; the sides were regularly formed with spars ; and the whole presented the idea of a mag- nificent theatre, illuminated with an immense profusion of lights. The floor consisted of solid marble ; and in several places magnifi- cent columns, thrones, altars, and other ob- jects, appeared, as if nature had designed to mock the curiosities of art. Our voices, upon speaking or singing, were redoubled to an astonishing loudness ; and upon the firing of a gun, the noise and reverberations were almost deafening. In the midst of this grand amphitheatre rose a concretion of about fif- teen feet high, that, in some measure, resem- bled an altar; from which, taking the hint, we caused mass to be celebrated there. The beautiful columns that shot up round the al- tar, appeared like candlesticks; and many other natural objects represented the custo- mary ornaments of this sacrament. " Below even this spacious grotto there seemed another cavern ; down which I ven- tured with my former mariner, and descended about fifty paces by means of a rope. I at last arrived at a small spot of level ground, where the bottom appeared different from that of the amphitheatre, being composed of a soft clay, yielding to the pressure, and in which I thrust a stick to about six feet deep. In this, however, as above, numbers of the most beautiful crystals were formed, one of which particularly resembled a table. Upon our egress from this amazing cavern, we per- ceived a Greek inscription upon a rock at the mouth, but so obliterated by time, that we could not read it. It seemed to import, that one Antipater, in the time of Alexander, had come thither; but whether he had penetrated into the depths of the cavern, he does not think fit to inform us." Such is the account of this beautiful scene, as communicated in a letter to Kircher. We have another, and a more copious description of it, by Tournefort, which is in every body's hands ; but I have given the above, both be- cause it was communicated by the first dis- coverer, and because it is a simple narrative of facts, without any reasoning upon them. According to Tournefort's account, indeed, we might conclude, from the rapid growth of the spars in this grotto, that it must every year be growing narrower, and that it must in time be choked up with them entirely ; but no such thing has happened hitherto, and the grotto at this day continues as spacious as we ever knew it. This is not a place for inquiry into the seeming vegetation of those stony substances, with which this and almost every cavern are incrusted : it is enough to observe, in gene- ral, that they are formed by an accumulation of that little gritty matter which is carried thither by the waters, and which in time ac- quires the hardness of marble. What in this place more imports us to know, is, how these amazing hollows in the earth came to be formed. And I think, in the three instances above mentioned, it is pretty evident, that their excavation has been owing to water. These finding subterraneous passages under the earth, and by long degrees hollowing the beds in which they flowed, the ground above them has slipped down closer to their surface, leaving the upper layers of the earth or stone still suspended ; the ground that sinks upon the face of the waters forming the floor of the cavern ; the ground or rock, that keeps sus- pended, forming the roof: and, indeed, there are but few of these caverns found without water, either within them, or near enough to point out their formation. 22 A HISTORY OF CHAPTER VIII. OF MINES, DAMPS, AND MINERAL VAPOURS. THE caverns, which we have been de- scribing, generally carry us but a very little way below the surface of the earth. Two hundred feet, at the utmost, is as much as the lowest of them is found to sink. The perpen- dicular fissures run much deeper; but few persons have been bold enough to venture down to their deepest recesses; and some few who have tried, have been able to bring back no tidings of the place, for unfortunately they left their lives below. The excavations of art have conducted us much farther into the bowels of the globe. Some mines in Hungary are known to be a thousand yards perpendicular downwards ; and I have been informed, by good authority, of a coal-mine in the north of England, an hundred yards deeper still. It is beside our present purpose to inquire into the peculiar contrivance and construction of these, which more properly belongs to the history of fossils. It will be sufficient to ob- serve in this place, that as we descend into the mint v s, the various layers of earth are seen as we have already described them; and in some of these are always found the metals or mine- rals for which the mine has been dug. Thus frequently gold is found dispersed and mixed with clay and gravel;" sometimes it is mingled with other metallic bodies, stones, or bitu- mens ; h and sometimes united with that most obstinate of all substances, platina, from which scarce any art can separate it. Silver is sometimes found quite pure ; c sometimes mixed with other substances and minerals. Copper is found in beds mixed with various substances, marbles, sulphurs, and pyrites. Tin, the ore of which is heavier than that of any other metal, is generally found mixed with every kind of matter : lead is also equally common ; and iron we well know can be ex- tracted from all the substances upon earth. a Ulloa. vol. ii. p. 470. b Ulloa, ibid. c Macquer's Chymistry, vol. i. p. 316. The variety of substances which are thus found in the bowels of the earth, in their native state, have a very different appearance from what they are afterwards taught to as- sume by human industry. The richest me- tals are very often less glittering and splendid than the most useless marcasites; and the basest ores are generally the most beautiful to the eye. This variety of substances, which compose the internal parts of our globe, is productive of equal varieties, both above and below its surface. The combination of the different minerals with each other, the heats which arise from their mixture, the vapours they diffuse, the fires which they generate, or the colds which they sometimes produce, are all either noxious or salutary to man ; so that in this great elaboratory of nature, a thousand benefits and calamities are forging, of which we are wholly unconscious ; and it is happy for us that we are so. Upon our descent into mines of consider- able depth, the cold seems to increase from the mouth as we descend ; e but after passing very low down, we begin by degrees to come into a warmer air, which sensibly grows hot- ter as we go deeper, till, at last, the labourers can scarcely bear any covering as they con- tinue working. This difference in the air was supposed by Boyle to proceed from magazines of fire that lay nearer the centre, and that diffused their heat to the adjacent regions. But we now know that it may be ascribed to more obvious causes. In some mines, the composition ot the earth all around is of such a nature, that, upon the admission of water or air, it fre- quently becomes hot, and often bursts out into eruptions. Besides this, as the external air cannot readily reach the bottom, or be renewed there, an observable heat is per- d Hill's Fossils, p. 628. e Boyle, vol. iii. p. 232. THE EARTH. 23 ceived below, without the necessity of recur- ring to the central heat for an explanation. Hence, therefore, there are two principal causes of the warmth at the bottom of mines : the heat of the substances of which the sides are composed ; and the want of renovation in the air below. Any sulphureous substance, mixed with iron, produces a very great heat, by the admission of water. If, for instance, a quantity of sulphur be mixed Avith a propor- tionable share of iron filings, and both kneaded together into a soft paste, with water, they will soon grow hot, and at last produce a flame. This experiment, produced by art, is very commonly effected within the bowels of the earth by nature. Sulphurs and irons are intimately blended together, and want only the mixture of water or air to excite their heat ; and this, when once raised, is communicated to all bodies that lie within the sphere of their operation. Those beau- tiful minerals called marcasites and pyrites, are often of this composition ; and wherever they are found, either by imbibing the moisture of the air, or having been by any means com- bined with water, they render the mine con- siderably hot. a The want of fresh air also, at these depths, is, as we have said, another reason for their being found much hotter. Indeed, without the assistance of art, the bottom of most mines would, from this cause, be insupportable. To remedy this inconvenience, the miners are often obliged to sink, at some convenient dis- tance from the mouth of the pit where they are at work, another pit, which joins the for- mer below, and which, in Derbyshire, is called an air-shaft. Through this the air circulates ; and thus the workmen are enabled to breathe freely at the bottom of the place ; which be- comes, as Mr. Boyle affirms, very commodious for respiration, and also very temperate as to heat and cold. b Mr. Locke, however, who has left us an account of the Mendip mines, seems to present a different picture. " The descent into theseisexceedinglydifficult and dangerous; for they are not sunk like wells, perpendicu- larly, but as the crannies of the rocks happen to run. The constant method is to swing down Kircher Mund. Subt. vol. ii. p. 216. k Boyle, vol. iii. p. 238. by a rope placed under the arms, and clam- ber along by applying both feet and hands to the sides of the narrow passage. The air is conveyed into them through a little passage that runs along the sides from the top, where they set up some turfs, on the lee-side of the hole, to catch and force it down. These turfs being removed to the windy side, or laid over the mouth of the hole, the miners below pre- sently want breath, and faint; and if sweet- smelling flowers chance to be placed there, they immediately lose their fragrancy, and stink like carrion." An air so putrefying can never be very commodious for respiration. Indeed, if we examine the complexion of most miners, we shall be very well able to form a judgment of the unwholesomeness of the place where they are confined. Their pale and sallow looks show how much the air is damaged by passing through those deep and winding ways, that are rendered humid by damps, or warmed with noxious exhala- tions. But although every mine is unwhole- some, all are not equally so. Coal-mines are generally less noxious than those of tin ; tin than those of copper ; but none are so dread- fully destructive as those of quicksilver. At the mines near the village of Idra, nothing can adequately describe the deplorable in- firmities of such as fill the hospital there; emaciated and crippled ; every limb con- tracted or convulsed, and some in a manner transpiring quicksilver at every pore. There was one man, says Dr. Pope, c who was not in the mines above half a year, and yet whose body was so impregnated with this mineral, that putting a piece of brass money in his mouth, or rubbing it between his fingers, it immediately became as white as if it had been washed over with quicksilver. In this manner all the workmen are killed sooner or later; first becoming paralytic, and (hen dying consumptive : and all this they sustain for the trifling reward of seven pence a day. But these metallic mines are not so noxious from their own vapours, as from those of the substances with which the ores are usually united, such as arsenic, cinnabar, bitumen, or vitriol. From the fumes of these, variously c Phil. Trans, vol. ii. p. 578. H 24 A HISTORY OF combined, and kept inclosed, are produced those various damps, that put on so many dreadful forms, and are usually so fatal. Sometimes those noxious vapours are per- ceived by the delightful fragrance of their smell," somewhat resembling the pea-blossom in bloom, from whence one kind of damp has its name. The miners are not deceived, however, by its flattering appearances ; but as they have thus timely notice of its coming, they avoid it while it continues, which is gene- rally during the whole summer season. Ano- ther shows its approach by the burning of the candles, which seem to collect their flame into a globe of light, and thus gradually lessen, till they are quite extinguished. From this, also, the miners frequently escape ; however, such as have the misfortune to be caught in it, either swoon away, and are suffocated, or slowly recover in excessive agonies. Here also is a third, called the fulminating damp, much more dangerous than either of the former, as it strikes down all before it like a flash of gunpowder, without giving any warning of its approach. But there is another, more deadly than all the rest, which is found in those places where the vapour has been long confined, and has been, by some accident, set free. The air rushing out from thence, always goes upon deadly errands ; and scarce any escape to describe the symptoms of its operations. Some colliers in Scotland, working near an old mine that had been long closed up, hap- pened, inadvertently, to open a hole into it, from the pit where they were then employed. By great good fortune, they at that time, per- ceived their error, and instantly fled for their lives. The next day, however, they were re- solved to renew their work in the same pit, and eight of them ventured down, without any great apprehensions ; but they had scarcely got to the bottom of the stairs that led to the pit, but, coming within the vapour, they all instantly dropped down dead, as if they had been shot. Amongst these unfortunate poor men, there was one whose wife was informed he was stifled in the mine ; and, as he hap- pened to be next the entrance, she so far ventured down as to see where he lay. As ehe approached the place, the sight of her Phil. Trans, vol. ii. p. 375. husband inspired her with a drsire to rescue him, if possible, from that dreadful situation; though a little reflection might have shown her it was then too late. But nothing could deter her; she ventured forward, and had scarce touched him with her hand, when the damp prevailed, and the misguided, but faith- ful creature, fell dead by his side. Thus, the vapours found beneath the sur- face of the earth are very various in their ef- fects upon the constitution : and they are not less in their appearances. There are many kinds that seemingly are no way prejudicial to health, but in which the workmen breathe freely; and yet in these, if a lighted candle be introduced, they immediately take fire, and the whole cavern at once becomes one furnace of flame. In mines, therefore, subject to damps of this kind, they are obliged to have recourse to a very peculiar contrivance to supply suffi- cient light for their operations. This is by a great wheel ; the circumference of which is beset with flints, which striking against steels placed for that purpose at the extremity, a stream of fire is produced, which affords light enough, and yet which does not set fire to the mineral vapour. Of this kind are the vapours of the mines about Bristol : on the contrary, in other mines, a single spark struck out from the collision of flint and steel, would set the whole shaft in a flame. In such, therefore, every precaution is used to avoid a collision; the workmen making use only of wooden instruments in digging ; and being cautious, before they en- ter the mine, to take out even the nails from their shoes. Whence this strange difference should arise, that the vapours of some mines catch fire with a spark, and others only with a flame, is a question that we must be content to leave in obscurity, till we know more of the nature both of mineral vapour and of fire This only we may observe, that gunpowder will readily fire with a spark, but not with the flame of a candle ; on the other hand, spirits of wine will flame with a candle, but not with a spark : but even here the cause of this dif- ference as yet remains a secret. As from this account of mines, it appears that the internal parts of the globe are filled with vapours of various kinds, it is not sur- prising that they should, at different times, THE EARTH. 25 reach the surface, and there put on various appearances. In (act, much of' the salubrity, and much of the unwholesomeness, of climates and soils, is to be ascribed to these vapours, which make their way from the bowels of the earth upwards, and refresh or taint the air with their exhalations. Salt mines, being na- turally cold," send forth a degree of coldness to the external air, to comfort and refresh it : on the contrary, metallic mines are known, not only to warm it with their exhalations, but often to destroy all kinds of vegetation by their volatile corrosive fumes. In some mines, dense vapours are plainly perceived issuing from their mouths, and sensibly warm to the touch. In some places, neither snow nor ice will continue on the ground that covers a mine ; and over others the fields are found destitute of verdure. b The inhabitants, also, are rendered dreadfully sensible of these sub- terraneous exhalations, being affected with such a variety of evils proceeding entirely from this cause, that books have been pro- fessedly written upon this class of disorders. Nor are these vapours, which thus escape to the surface of the earth, entirely uncon- fined ; for they are frequently, in a manner, circumscribed to a spot. The grotto Del Cane, near Naples, is an instance of this; the noxious effects of which have made that cavern so very famous. This grotto, which has so much employed the attention of tra- vellers, lies within four miles of Naples, and is situated near a large lake of clear whole- some water. c Nothing can exceed the beauty of the landscape which this lake affords; being surrounded with hills covered with forests of the most beautiful verdure, and the whole bearing a kind of amphitheatrical appearance. However, this region, beautiful as it appears, is almost entirely uninhabited ; the few pea- sants that necessity compels to reside there, looking quite consumptive and ghastly, from the poisonous exhalations that rise from the earth. The famous grotto lies on the side of a hill, near which place a peasant resides, who keeps a number of dogs for the purpose of showing the experiment to the curious. These poor animals always seem perfectly sen- sible of the approach of a stranger, and endea- vour to get out of the way. However, their at- Phil. Trans. voL ii. p. 523. b Boyle, vol. iii. p. 238. tempts being perceived, they are taken and brought to the grotto ; the noxious effects of which they have so frequently experienced. Upon entering this place, which is a little cave, or hole rather, dug into the hill, about eight feet high, and twelve feet long, the ob- server can see no visible mark of its pestilen- tial vapour; only to about a foot from the bottom, the wall seems to be tinged with a colour resembling that which is given by stagnant waters. When the dog, this poor philosophical martyr, as some have called him, is held above this mark, he does not seem to feel the smallest inconvenience ; but when his head is thrust down lower, he strug- gles to get free for a little ; but in the space of four or five minutes he seems to lose all sensation, and is taken out seemingly without life. Being plunged in the neighbouring lake, he quickly recovers, and is permitted to run home, seemingly without the smallest in- jury. This vapour, which thus for a time suffo- cates, is of the humid kind, as it extinguishes a torch, and sullies a looking-glass ; but there are other vapours perfectly inflammable, and that only require the approach of a candle to set them blazing. Of this kind was the burn- ing well at Brosely, which is now stopped up ; the vapour of which, when a candle was brought within about a foot of the surface of the water, caught flame like spirits of wine, and continued blazing for several hours after. Of this kind, also, are the perpetual fires in the kingdom of Persia. In that province, where the worshippers of fire hold their chief mysteries, the whole surface of the earth, for some extent, seems impregnated with in- flammable vapours. A reed stuck into the ground continues to burn like a flambeau; a hole made beneath the surface of the earth, instantly becomes a furnace, answering all the purposes of a culinary fire. There they make lime by merely burying the stones in the earth; and watch with veneration the appearances of a flame that has not been ex- tinguished for times immemorial. How dif- ferent are men in various climates ! This de- luded people worship these vapours as a deity, which in other parts of the world are considered as one of the greatest evils. c Kircher, Mund. Subt. vol. i. p. 191. 26 A HISTORY OF CHAPTER IX. OF VOLCANOES AND EARTHQUAKES. MINES and caverns, as we have said, reach but a very little way under the surface of the earth, and we have hitherto had no opportunities of exploring further. Without all doubt, the wonders that are still unknown surpass those that have been represented, as there are depths of thousands of miles which are hidden from our inquiry. The only tidings we have from those unfathomable re- gions are by means of volcanoes, those burn- ing mountains that seem to discharge their materials from the lowest abysses of the earth. a A volcano may be considered as a cannon of immense size, the mouth of which is often near two miles in circumference. From this dreadful aperture are discharged torrents of dame and sulphur, and rivers of melted metal. Whole clouds of smoke and ashes, with rocks of enormous size, are discharged to many miles distance; so that the force of the most powerful artillery, is but as a breeze agitating a feather in comparison. In the deluge of fire and melted matter which runs down the sides of the mountain, whole cities are sometimes swallowed up and consumed. Those rivers of liquid fire are sometimes two hundred feet deep ; and, when they harden, frequently form considerable hills. Nor is the danger of these confined to the eruption only : but the force of the internal fire strug- gling for vent, frequently produces earth- quakes through the whole region where the volcano is situated. So dreadful have been these appearances, that men's terrors have added new horrors to the scene, and they have regarded as prodigies, what we know to be the result of natural causes. Some philosophers have considered them as vents communicating with the fires of the centre; and the ignorant, as the mouths of hell itself. Astonishment produces fear, and fear super- stition : the inhabitants of Iceland believe the bellowings of Hecla are nothing else but the Buffon, vol. i. p. 291. cries of the damned, and that its eruptions are contrived to increase their tortures. But if we regard this astonishing scene of terror with a more tranquil and inquisitive eye, we shall find that these conflagrations are produced by very obvious and natural causes. We have already been apprised of the various mineral substances in the bosom of the earth, and their aptness to burst out into flames. Marcasites and pyrites, in par- ticular, by being humified with water or air, contract this heat, and often endeavour to expand with irresistible explosion. These, therefore, being lodged in the depths of the earth, or in the bosom of mountains, and being either washed by the accidental influx of waters below, or fanned by air, insinuating itself through perpendicular fissures from above, take fire at first by only heaving in earthquakes, but at length by bursting through every obstacle, and making their dreadful discharge in a volcano. These volcanoes are found in all parts of the earth: In Europe there are three that are very remarkable; 2Etna in Sicily, Vesuvius in Italy, and Hecla in Iceland. jEtna has been a volcano for ages immemorial. Its eruptions are very violent, and its discharge has been known to cover the earth eighty-six feet deep. In the year 1 537, an eruption of this mountain produced an earthquake through the whole island for twelve days, overturned many houses, and at last formed a new aperture, which overwhelmed all within five leagues round. The cinders thrown up were driven even into Italy, and its burnings were seen at Malta, at the distance of sixty leagues. " There is nothing more awful," says Kircher, " than the eruptions of this mountain, nor nothing more dangerous than attempting to examine its appearances, even long after the eruption has ceased. As we attempt to clamber up its steepy sides, every step we take upward, the feet sink back half way. Upon arriving near the summit, ashes and snow, with an ill- THE EARTH. 27 assorted conjunction, present nothing but ob- jects of desolation. Nor is this the worst, for, as all places are covered over, many caverns are entirely hidden from the sight, into which, if the inquirer happens to fall, he sinks to the bottom, and meets inevitable de- struction. Upon coming to the edge of the great crater, nothing can sufficiently represent the tremendous magnificence of the scene. A gulf two miles over, and so deep that no bottom can be seen; on the sides pyramidi- cal rocks starting out between apertures that emit smoke and flame; all this accompanied with a sound that never ceases, louder than thunder, strikes the bold with horror, and the religious with veneration for HIM that has power to control its burnings." In the descriptions of Vesuvius or Hecla, we shall find scarcely any thing but a repe- tition of the same terrible objects, but rather lessened, as these mountains are not so large as the former. The crater of Vesuvius is but a mile across, according to the same author; whereas that of ^Etna is two. On this par- ticular, however, we must place no depen- dence, as these caverns every day alter; being lessened by the mountain's sinking in at one eruption, and enlarged by (he fury of another. It is not one of the least remarkable particu- lars respecting Vesuvius, that Pliny the na- turalist was suffocated in one of its eruptions; for his curiosity impelling him too near, he found himself involved in smoke and cinders when it was too late to retire; and his com- panions hardly escaped to give an account of the misfortune. It was in that dreadful erup- tion that the city of Herculaneum was over- whelmed; the ruins of which have lately been discovered at sixty feet distance below the surface, and, what is still more remarkable, forty feet below the bed of the sea. One of the most remarkable eruptions of this moun- tain was in the year 1707, which is finely de- scribed by Valetta: a part of whose descrip- tion I shall beg leave to translate. "Towards the latter end of summer, in the year 1707, the mount Vesuvius, that had for a long time been silent, now began to give some signs of commotion. Little more than internal murmurs at first were heard, that seemed to contend within the lowest depths of the mountain; no flame, nor even any smoke, was ! as yet seen. Soon after some smoke appear- ed by day, and a flame by night, which seem- ed to brighten all the campania. At inter- vals, also, it shot ofT substances with a sound very like that of artillery, but which, even at so great a distance as we were at, infinitely exceeded them in greatness. Soon after it began to throw up ashes, which becoming the sport of the winds, fell at great distances, and some many miles. To this succeeded showers of stones, which killed many of the inhabitants of the valley, but made a dreadful ravage among the cattle. Soon after a torrent of burning matter began to roll down the sides of the mountain, at first with a slow and gen- tle motion, but soon with increased celerity. The matter thus poured out, when cold, seem- ed upon inspection to be of vitrified earth, the whole united into a mass of more than stony hardness. But what was particularly observable was, that upon the whole surface of these melted materials, a light spongy stone seemed to float, while the lower body was of the hardest substance of which our roads are usually made. Hitherto there were no ap- pearances but what had been often remarked before; but on the third or fourth day, seem- ing flashes of lightning were shot forth from the mouth of the mountain, with a noise far exceeding the loudest thunder. These flashes, in colour and brightness, resembled what we usually see in tempests, but they assumed a more twisted and serpentine form. After this followed such clouds of smoke and ashes, that the whole city of Naples, in the midst of the day, was involved in nocturnal darkness, and the nearest friends were unable to distinguish each other in this frightful gloom. If any per- son attempted to stir out without torch-light, he was obliged to return, and every part of the city was filled with supplications and ter- ror. At length, after a continuance of some hours, about one o'clock at midnight, the wind blowing from the north, the stars began to be seen; the heavens, though it was night, began to grow brighter; and the eruptions, after a continuance of fifteen days, to lessen. The torrent of melted matter was seen to ex- tend from the mountain down to the shore; the people began to return to their former dwellings, and the whole face of nature to resume its former appearance." I 28 A HISTORY OF The famous Bishop Berkley gives an ac- count of one of these eruptions in a manner something different from the former." " In the year 1717, and the middle of April, with much dilficulty I reached the top of Mount Vesu- vius, in which I saw a vast aperture full of smoke, which hindered me from seeing its depth and figure. I heard within that horrid gulf certain extraordinary sounds, which seemed to proceed from the bowels of the mountain, u sort of murmuring, sighing, dash- ing sound ; and, between whiles, a noise like that of thunder or cannon, with a clattering like that of tiles falling from the tops of houses into the streets. Sometimes, as the wind changed, the smoke grew thinner, discovering a very ruddy flame, and the circumference of the crater streaked with red and several shades of yellow. After an hour's stay, the smoke, being moved by the wind, gave us short and partial prospects of the great hol- low; in the flat bottom of which I could dis- cern two furnaces almost contiguous; that on the left seeming about three yards over, glowing with ruddy flame, and throwing up red-hot stones with a hideous noise, which, as they fell back, caused the clattering al- ready taken notice of. May 8, in the morning, I ascended the top of Vesuvius a second time, and found a different face of things. The smoke ascending upright, gave a full prospect of the crater, which, as I could judge, was about a mile in circumference, and a hundred yards deep. A conical mount had been formed, since my last visit, in the middle of the bottom, which I could see was made by the stones, thrown up and fallen back again into the crater. In this new hill remained the two furnaces already mentioned. The one was seen to throw up every three or four minutes, with a dreadful sound, a vast number of red-hot stones, at least three hundred feet higher than my head, as I stood upon the brink; but as there was no wind, they fell perpendicularly back from whence they had been discharged. The other was filled with red-hot liquid matter, like that in the furnace of a glass-house, raging and working like the waves of the sea, with a short abrupt noise. This matter would sometimes boil over, and Phil. Trans. voL ii. p. 209. run down the side of the conical hill, appear- ing at first red hot, but changing colour as it hardened and cooled. Had the wind driven in our faces, we had been in no small danger of stifling by the sulphureous smoke, or being killed by the masses of melted minerals that were shot from the bottom. But as the wind was favourable, I had an opportunity of sur- veying this amazing scene for above an hour and a half together. On the fifth of June, after a horrid noi*e, the mountain was seen at Naples to work over; and, about three days after, its thunders were renewed so, that not only the windows in the city, but all the houses, shook. From that time it con- tinued to overflow, and sometimes at night were seen columns of fire shooting upward from its summit. On the tenth, when all was thought to be over, the mountain again re- newed its terrors, roaring and raging most violently. One cannot form ajuster idea of the noise, in the most violent fits of it, than by imagining a mixed sound made up of the raging of a tempest, the murmur of a troubled sea, and the roaring of thunder and artillery, confused all together. Though we heard this at a distance of twelve miles, yet it was very terrible. I therefore resolved to approach nearer to the mountain; and, accordingly, three or four of us got into a boat, and were set ashore at a little town situated at the foot of the mountain. From thence we rode about four or five miles, before we came to the tor- rent of fire that was descending from the side of the volcano; and here the roaring grew exceedingly loud and terrible as we ap- proached. I observed a mixture of colours in the cloud, above the crater, green, yellow, red, and blue. There was likewise a ruddy dismal light in the air, over that tract where the burning river flowed. These circum- stances, set off and augmented by the horror of the night, made a scene the most uncom- mon and astonishing I ever saw; which still increased as we approached the burning river. Imagine a vast torrent of liquid fire, rolling from the top down the side of the mountain, and with irresistible fury bear- ing down and consuming vines, olives, and houses ; and divided into different channels, according to the inequalities of the mountain. The largest stream seemed half a mile broad THE EARTH. at least, and five miles long. I walked so far before my companions up the mountain, along the side of the river of tire, that I was obliged to retire in gre.it haste, the sulphureous stream having surprised me, and almost taken away my breath. During our return, which was about three o'clock in the morning, the roar- ing of the mountain was heard all the way, while we observed it throwing up huge spouts of fire and burning stones, which, falling, re- sembled the stars in a rocket. Sometimes I observed two or three distinct columns of flame, and sometimes one only, that was large enough to fill the whole crater. These burn- ing columns, and fiery stones, seemed to be shot a thousand feet perpendicular above the summit of the volcano; and in this manner the mountain continued raging for six or eight days after. On the 18th of the same month, the whole appearance ended, and the moun- tain remained perfectly quiet, without any visible smoke or flame. The matter which is found to roll down from the mouth of all volcanoes in general, resembles the dross that is thrown from a smith's forge. But it is different, perhaps, in various parts of the globe ; for, as we have already said, there is not a quarter of the world that has not its volcanoes. In Asia, particularly in the islands of the Indian Ocean, there are many. One of the most famous is that of Albouras, near Mount Taurus, the (summit of which is continually on fire, and covers the whole adjacent country with ashes. In the island of Ternate there is a volcano, which, some travellers assert, burns most fu- riously in the times of the equinoxes, because of the winds which then contribute to increase the flames. In the Molucco islands there are many burning mountains; they are also seen in Japan, and the islands adjacent ; and in Java and Sumatra, as well as in other of the Philippine islands. In Africa there is a cavern, near Fez, which continually sends forth either smoke or flames. In the Cape de Verde islands, one of them, called the Island del Fuego, continually burns ; and the Portuguese, who frequently attempted a set- tlement there, have as often been obliged to desist. The Peak of Teneriffe is, as every one knows, a volcano, that seldom desists from eruptions. But, of all parts of the earth, America is the place where those dreadful irregularities of nature are the most conspicu- ous. Vesuvius, and YEtria itself, are but mere fireworks in comparison to the burning- mountains of the Andes ; which, as they are the highest mountains of the world, so also are they the most formidable for their erup- tions. The mountain of Arequipa in Peru, is one of the most celebrated ; Carassa, and Malahallo, are very considerable ; but that of Cotopaxi, in the province of Quito, exceeds any thing we have hitherto read or heard of. The mountain of Cotopaxi, as described by Ulloa," is more than three miles perpendicular from the sea ; and it became a volcano at the time of the Spaniards' first arrival in that country. A new eruption of it happened in the year 1743,having been some days preceded by a continual roaring in its bowels. The sound of one of these mountains is not, like that of the volcanoes in Europe, confined to a pro- vince, but is heard at a hundred and fifty miles distance. 1 * " An aperture was made in the summit of this immense mountain ; and three more about equal heights near the mid- dle of its declivity, which was at that time buried under prodigious masses of snow. The ignited substances ejected on that occasion, mixed with a prodigious quantity of ice and snow, melting amidst the flames, were car- ried down with such astonishing rapidity, that in an instant the valley from Callo to Latu- cunga was overflowed; and besides its ravages in bearing down the houses of the Indians, and other poor inhabitants, great numbers of people lost their lives. The river of Latu- cunga was the channel of this terrible flood ; till being too small for receiving such a pro- digious current, it overflowed the adjacent country, like a vast lake, near the town, and carried away all the buildings within its reach. The inhabitants retired into a spot of higher ground behind the town, of which those parts which stood within the limits of the current were totally destroyed. The dread of still greater devastations did not subside for three days; during which the volcano ejected cin- ders, while torrents of melted ice and snow poured down its sides. The eruption lasted several days, and was accompanied with ter- a Ulloa, vol. i. p. 442. b Ulloa, vol. i. p. 442. 30 A HISTORY OF rible roarings of the wind, rushing through the volcano, still louder than the former rumblings in its bowels. At last all was quiet, neither fire nor smoke to be seen, nor noise to be heard; till, in the ensuing year, the flames again appeared with recruited vio- lence, forcing their passage through several other parts of the mountain, so that in clear nights the flames being reflected by the trans- parent ice, formed an awfully magnificent illumination." Such is the appearance and the effect of those lires which proceed from the more inward recesses of the earth : for that they generally come from deeper regions than man has hitherto explored, I cannot avoid thinking, contrary to the opinion of Mr. Buffbn, who supposes them rooted but a very little way be- low the bed ofthe mountain. "We can never sup- pose," says this great naturalist, "that these substances are ejected from any great distance below, if we only consider the great force already required to fling them up to such vast heights above the mouth ofthe mountain ; if we consider the substances thrown up, which we shall find upon inspection to be the same with those of the mountain below ; if we take into our consideration, that air is always necessary to keep up the flame ; but, most of all, if we attend to one circumstance, which is, that if these substances were exploded from a vast depth below, the same force re- quired to shoot them up so high, would act against the sides of the voJcano, and tear the whole mountain in pieces." To all this spe- cious reasoning, particular answers might be easily given ; as, that the length of the funnel increases the force of the explosion ; that the sides of the funnel are actually often burst with the great violence of the flame ; that air may be supposed at depths at least as far as the perpendicular fissures descend. But the best answer is a well-known fact ; namely, that the quantity of matter discharged from ./Etna alone, is supposed, upon a moderate computation, to exceed twenty times the original bulk ofthe mountain." The greatest part of Sicily seems covered with its erup- tions. The inhabitants of Catanea have found, at the distance of several miles, streets and houses sixty feet deep, overwhelmed by the lava or matter it has discharged. But what is still more remarkable, the walls of these very houses have been built of materials evi- dently thrown up by the mountain. The in- ference from all this is very obvious ; that the matter thus exploded cannot belong to the mountain itself, otherwise it would have been quickly consumed ; it cannot be derived from moderate depths, since its amazing quantity evinces, that all the places near the bottom must have long since been exhausted; nor can it have an extensive, and, if I may so call it, a superficial spread, for then the country round would be quickly undermined ; it must, therefore, be supplied from the deeper regions ofthe earth ; those undiscovered tracts where the Deity performs his wonders in solitude, satisfied with self-approbation ! CHAPTER X. OF EARTHQUAKES. HAVING given the theory of volcanoes, we have in some measure given also that of earthquakes. They both seem to proceed from the same cause, only with this differ- ence, that the fury of the volcano is spent in the eruption; that of an earthquake spreads Kircher, Mund. Subt. vol. i. p. 202. wider, and acts more fatally by being confin- ed. The volcano only affrights a province ; earthquakes have laid whole kingdoms in ruin. Philosophers'* have taken some pains to dis- tinguish between the various kinds of earth- b Aristotle, Agricola, Buffon. THE EARTH. 31 quakes, such as the tremulous, the pulsative, the perpendicular, and the inclined ; but these are rather the distinctions of art than of nature, mere accidental differences arising from the situation of the country or of the cause. If, for instance, the confined h're acts directly under a province or a town, it will heave the earth perpendicularly upward, and produce a perpendicular earthquake. If it acts at a distance, it will raise that tract obliquely, and thus the inhabitants will per- ceive an inclined one. Nor does it seem to me that there is much greater reason for Mr. BufFon's distinction of earthquakes ; one kind of which he supposes" to be produced by fire in the manner of vol- canoes, and confined but to a very narrow circumference. The other kind he ascribes to the struggles of confined air, expanded by heat in the bowels of the earth, and endeavour- ing to get free. For how do these two causes differ? Fire is an agent of no power whatso- ever without air. It is the air, which being at first compressed, and (hen dilated in a cannon, that drives the ball with such force. It is the air struggling for vent in a volcano, that throws up its contents to such vast heights. In short, it is the air confined in the bonds of the earth, and acquiring elasticity by heat. that produces all those appearances which are generally ascribed to the operation of fire. When, therefore, we are told lh;tt there are two causes of earthquakes, we only learn that a greater or smaller quantity of heat pro- duces those terrible effects ; for air is the only active operator in either. Some philosophers, however, have been willing to give the air as great a share in pro- ducing these terrible efforts as they could ; and, magnifying its powers, have called in but a very moderate degree of heat to put it in action. Although experience tell us that the earth is full of inflammable materials, and tint fires are produced wherever we descend ; although it tells us that those countries where there are volcanoes, are most subject to earth- quakes; yet they step out of their way, and so find a new solution. These only allow but just heat enough to produce the most dreadful phenomena, and, backing their assertions with * Buffbn, vol. ii. p. 328. io. 4. long calculations, give theory an air of de- monstration. Mr. Amontons b has been par- ticularly sparing of the internal heat in this respect ; and has shown, perhaps accurately enough, that a very moderate degree of heat may suffice to give the air amazing powers of expansion. It is amazing enough, however, to trace the progress of a philosophical fancy let loose in imaginary speculations. They run thus: "A very moderate degree of heat may bring the air into a condition capable of producing earthquakes ; for the air, at the depth of forty-three thousand five hundred and twenty- eight fathom below the surface of the earth, becomes almost as heavy as quicksilver. This, however, is but a very slight depth in comparison of the distance to the centre, and is scarcely a seventieth part of the way. The air, therefore, at the centre, must be infinitely heavier than mercury, or any body that we know of. This granted, we shall take some- thing more, and say, that it is very probable there is nothing but air at the centre. Now let us suppose this air heated, by some means, even to the degree of boiling water, (as we have proved that the density of the air is here very great.) its elasticity must be in propor- tion ; a heat, therefore, which at the surface of the earth would have produced but a slight expansive force, must, at the centre, produce one very extraordinary, and, in short, be per- fectly irresistible. Hence, this force may, with great ease, produce earthquakes; and, if increased, it may convulse the globe; it may (by only adding figures enough to the calculation) destroy the solar system, and even the fixed stars themselves." These reveries generally produce nothing; for, as I have ever observed, increased calculations, while they seem to tire the memory, give the reasoning faculty perfect repose. However, as earthquakes are the most formidable ministers of nature, it is not to be wondered that a multitude of writers have been curiously employed in their considera- tion. Woodward has ascribed the cause to a stoppage of the waters below the earth's surface by some accident. These being thus accumulated, ami yet acted upon by fires. b Memoires de 1'Academie de Sciences. An. 1703. K 32 A HISTORY OF which he supposes still deeper, both contri- bute to heave up the earth upon their bosom. This, he thinks, accounts for the lakes of water produced in an earthquake, as well as for the fires that sometimes burst from the earth's surface upon those dreadful occasions. There are others who have supposed that the earth may be itself the cause of its own convulsions. " When," say they, "the root or basis of some large tract is worn away by a fluid under- neath, the earth sinking therein, its weight occasions a tremour of the adjacent parts, sometimes producing a noise, and sometimes an inundation of water." Not to tire the reader with a history of opinions instead of facts, some have ascribed them to electricity, and some to the same causes that produce thunder. It would be tedious, therefore, to give all the various opinions that have employed the speculative on this subject. The activity of the internal heat seems alone sufficient to account for every appearance that attends these tremendous irregularities of nature. To conceive this distinctly, let us suppose, at some vast distance under the earth, large quantities of inflammable matter, pyrites, bitumens, and marcasites, disposed, and only waiting tor the aspersion of water, or the hu- midity of the air, to put their fires in motion: at last, this dreadful mixture arrives ; waters find their way into those depths, through the perpendicular fissures ; or air insinuates itself through the same minute apertures: instantly new appearances ensue ;_ those substances, which for ages before lay dormant, now con- ceive new apparent qualities ; they grow hot, produce new air, and ouly want room for ex- pansion. However, the narrow apertures by which the air or water had at first admission, are now closed up ; yet as new air is con- tinually generated, and as the heat every mo- ment gives this air new elasticity, it at length bursts, and -dilates all round; and, in its struggles to get free, throws all above it into similar convulsions. Thus an earthquake is produced, more or less extensive, according to the depth or the greatness of the cause. But before we proceed with the causes, let us take a short view of the appearances which Plin. lib. ii. cap. 86. have attended the most remarkable earth- quakes. By these we shall see how far the theorist corresponds with the historian. The greatest we find in antiquity is that mentioned by Hiny, a in which twelve cities in Asia Mi- nor were swallowed up in one night : lie tells us also of another, near the lake Thrasymene, which was not perceived by the armies of the Carthaginians and Romans, that were then engaged near that lake, although it shook the greatest part of Italy. In another place b he gives the following account of an earth- quake of an extraordinary kind. " When Lucius Marcus and Sextus Julius were con- suls, there appeared a very strange prodigy of the earth, (as I have read in the book of ./Etruscan discipline,) which happened in the province of Mutina. Two mountains shocked against each other, approaching and retir- ing with the most dreadful noise. They, at the same time, and in the midst of the day, appeared to cast forth fire and smoke, while a vast number of Roman knights and travel- lers from the jEmilian Way, stood and con- tinued amazed spectators. Several towns were destroyed by this shock; and all the animals that were near them were killed." In the times of Trajan, the city of Antioch, and a great part of the adjacent country, was buried by an earthquake. About three hun- dred years after, in the times of Justinian, it was once more destroyed, together with forty thousand inhabitants ; and, after an interval of sixty years, the same ill-fated city was a third time overturned, with the loss of not less than sixty thousand souls. In the year 1182, most of the cities of Syria, and the kingdom of Jerusalem, were destroyed by the same accident. In the year 1594, the Italian historians describe an earthquake at Puteoli, which caused the sea to retire two hundred yards from its former bed. But one of those most particularly describ- ed in history, is that of the year 1693; the damages of which were chiefly felt in Sicily, but its motion perceived in Germany, France, and England. It extended to a circumfer- ence of two thousand six hundred leagues; chiefly affecting the sea-coast and great riv- ers; more perceivable also upon the nioun- b Plin. lib. iii. cap. 85. THE EARTH. 33 tains than in the valleys. Its motions were so rapid, that those who lay at their length were tossed from side to side, as upon a roll- ing billow.* The walls were dashed from their foundations ; and no less than fifty-four cities, with an incredible number of villages, were either destroyed or greatly damaged. The city of Catanca, in particular, was utterly overthrown. A traveller, who was on his way thither, at the distance of some miles, per- ceived a black cloud, like night, hanging- over the place. The sea, all of a sudden, began to roar; Mount J^tna to send forth great spires of flame; and soon after a shock ensued, with a noise as if all the artillery in the world had been at once discharged. Our traveller, being obliged to alight instantly, felt himself raised a foot from the ground ; and turning his eyes to the city, he, with amazement, saw nothing but a thick cloud of dust in the air. The birds flew about asto- nished; the sun was darkened ; the beasts ran howling from the hills; and although the shock did not continue above three minutes, yet near nineteen thousand of the inhabitants of Sicily perished in the ruins. Catanea, to which city the describer was travelling, seem- ed the principal scene of ruin; its place only was to be found ; and not a footstep of its former magnificence was to be seen remain- ing. - The earthquake which happened in Ja- maica, in 1692, was very terrible, and its description sufficiently minute. " In two minutes' time it destroyed the town of Port Royal, and sunk the houses in a gulf forty fathoms deep. It was attended with a hollow rumbling noise, like that of thunder; and," in less than a minute, three parts of the houses, and their inhabitants, were all sunkquite under water. While they were thus swallowed up on one side of the street, on the other the houses were thrown into heaps; the sand of the streets rising like the waves of the eea, lifting up those that stood upon it, and immediately overwhelming them in pits. All the wells discharged their waters with the most vehement agitation. The sea felt an equal share of turbulence, and, bursting over its mounds, deluged all that came in its way. Phil. Trans, The fissures of the earth were, in some places, so great, that one of the streets appeared twice as broad as formerly. In many places, however, it opened and closed again, and continued this agitation for some time. Of these openings, two or three hundred might be seen at a time ; in some whereof the peo- ple were swallowed up ; in others, the earth closing, caught them by the middle, and thus crushed them instantly to death. Other openings, still more dreadful than the rest, swallowed up whole streets ; and others, more formidable, spouted up whole cataracts of water, drowning such as the earthquake had spared. The whole was attended with the most noisome stench ; while the thunder- ing of the distant falling mountains, the whole sky overcast with a dusky gloom, and the crash of falling habitations, gave unspeaka- ble horror to the scene. After this dreadful calamity was over, the whole island seemed converted into a scene of desolation ; scarcely a planter's house was left standing ; almost all were swallowed up; houses, people, trees, shared one universal ruin; and in their places appeared great pools of water, which, when dried up by the sun, left only a plain of barren sand, without any vestige of former inhabi- tants. Most of the rivers, during the earth- quake, were stopped up by the falling in of the mountains ; and it was not till after some time that they made themselves new channels. The mountains seemed particularly attacked by the force of the shock ; and it was sup- posed that the principal seat of the concus- sion was among them. Those who were saved got on board ships in the harbour, where many remained above two months; the shocks continuing, during that interval, with more or less violence every day." As this description seems to exhibit all the appearances that usually make up the cata- logue of terrors belonging to an earthquake. I will suppress the detail of that which hap- pened at Lisbon in our own times, and which is too recent to require a description. In fact, there are few particulars in the accounts of those who were present at that scene of deso- lation, that we have not more minutely and accurately transmitted to us by former wri- ters, whose narratives I have for that reason preferred, I will therefore close this descrip- 34 A HISTORY OF tion of human calamities with the account of the dreadful earthquake at Calabria, in 1638. It is related by the celebrated Fa- ther Kircher, as it happened while he was on his journey to visit Mount ^Etna. and the rest of the wonders that lie towards the south of Italy. I need scarcely inform the reader, that Kircher is considered, by scholars, as one of the greatest prodigies of learning. "Having hired a boat, in company with four more, two friars of the order of St. Fran- cis, and two seculars, we launched, on the twenty-fourth of March, from the harbour of Messina, in Sicily, and arrived the same day at the promontory of Pelorus. Our destina- tion was for the city of Euphaemia, in Calabria, where we had some business to transact, and where we designed to tarry for some time. However, Providence seemed willing to cross our design; for we were obliged to continue for three days at Pelorus, upon account of the weather ; and though we often put out to sea, yet we were as often driven back. At length, however, wearied with the delay, we resolved to prosecute our voyage ; and, al- though the sea seemed more than usually agitated, yet we ventured forward. The gulf of Charybdis, which we approached, seemed whirled round in such a manner, as to form a vast hollow, verging to a point in the centre. Proceeding onward, and turning my eyes to ^Etna, I saw it cast forth large volumes of smoke, of mountainous sizes, which entirely covered the whole island, and blotted out the very shores from my view. This, to- gether with the dreadful noise, and the sul- phureous stench, which was strongly per- ceived, filled me with apprehensions that some more dreadful calamity was impending. The sea itself seemed to wear a very unusual appearance ; those who have seen a lake in a violent shower of rain covered all over with bubbles, will conceive some idea of its agita- tions. My surprise was still increased by the calmness and serenity of the weather; not a breeze, not a cloud, which might be suppos- ed to put all nature thus into motion. I therefore warned my companions that an earthquake was approaching ; and, after some time, making for the shore with all possible diligence, we landed at Tropae, happy and thankful for having escaped the threatening dangers of the sea. " But our triumphs at land were of short duration ; for we had scarcely arrived at the Jesuits'College in thatcity, when our ears were stunned with a horrid sound, resembling that of an infinite number of chariots driven fierce- ly forward, the wheels rattling, and the thongs cracking. Soon after this, a most dreadful earthquake ensued, so that the whole tract upon which we stood seemed to vibrate, as if we were in the scale of a balance that con- tinued wavering. This motion, however, soon grew more violent; and being no longer able to keep my legs, I was thrown prostrate upon the ground. In the mean time, the universal ruin round me redoubled my amazement. The crash of falling houses, the tottering of towers, and the groans of the dying, all con- tributed to raise my terror and despair. On every side of me I saw nothing but a scene of ruin, and danger threatening wherever I should fly. I commended myself to God, as my last great refuge. At that hour, Ohow vain was every sublunary happiness ! wealth, honour, empire? wisdom, all mere useless sounds, and as empty as the bubbles in the deep. Just standing on the threshold of eternity, nothing but God was my pleasure; and the nearer I ap- proached, I only loved him the more. After some time, however, finding that I remained unhurt amidst the general concussion, I re- solved to venture for safety, and running as- fast as I could, reached the shore, but al- most terrified out of my reason. I did not search long here till I found the boat in which I had landed, and my companions also, whose terrors were even greater than mine. Our meeting was not of that kind where every one is desirous of telling his own happy escape ; it was all silence, and a gloomy dread of im- pending terrors. " Leaving this seat of desolation, we pro- secuted our voyage along the coast, and the next day came to Rochetta, where we landed, although the earth still continued in violent agitations. But we were scarcely arrived at our inn, when we were once more obliged to return to the boat, and i about half an hour we saw the greatest part of the town, and the inn at which we had set up, dashed to the ground, and burying all iut scenes of ruin and horror appeared; towns and castles levelled to the ground ; Strom- balo, though at sixty miles distance, belching forth tlaines in an unusual manner, and with a noise which I could distinctly hear. But my attention was quickly turned from more remote to contiguous danger. The rumbling sound of an approaching earthquake, which we by this time were grown acquainted with. alarmed us for the consequences ; it every moment seemed to grow louder, and to ap- proach more near. The place on which we stood now began to shake most dreadfully, so that being unable to stand, my compani- ons and I caught hold of whatever shrub grew next us, and supported ourselves in that man- ner. " After some time, this violent paroxysm ceasing, we again stood up, in order to pro- secute our voyage to Euphaemia, that lay within sight. In the mean time, while we were preparing for this purpose. I turned my eyes towards the city, but could see only a frightful dark cloud that seemed to rest upon the place. This the more surprised i.b, as the weather was so very serene. We waited, therefore, till the cloud was passed away; then turning to look for the city, it was to- tally sunk. Wonderful to tell ! nothing but a dismal and putrid lake was to be seen where it stood. We looked about to find some one that could tell us of its sad catas- trophe, but could see none ! All was become a melancholy solitude! a scene of hideous de- solation ! Thus proceeding pensively along, in quest of some human being that could give us some little information, we at length saw a boy sitting by the shore, and appearing stupified with terror. Of him, therefore, we inquired concerning the fate of the city, but he could not be induced to give us an an- swer. We entreated him with every ex- pression of tenderness and pity to tell us : but his senses were quite wrapt up in the contemplation of the danger he had escaped. We offered him some victuals, but he seemed to loathe the sight. We still persisted in our offices of kindness ; but he only pointed to the place of the city, like one out of his senses ; and then running up into the woods, was never heard of after. Such was the fate of the city of EuphaBmia! and as we continued our melancholy course along the shore, the whole coast, for the space of two hundred miles, presented nothing but the remains of cities, and men- scattered, without an habita- tion, over the fields. Proceeding thus along, we at length ended our distressful voyage by arriving at Naples, after having escaped a thousand dangers both at sea and land." The reader, I hope, w ill excuse me for this long translation from a favourite writer, and that the sooner, as it contains some particulars relative to earthquakes not to be found else- where. From the whole of these accounts we may gather, that the most concomitant circumstances are these : A rumbling sound before the earthquake. This proceeds from the air or fire, or both, forcing their way through the chasms of the earth, and endeavouring to get free; which is also heard in volcanoes. A violent agitation or heaving of the sea, sometimes before and sometimes after that at land. This agitation is only a similar effect produced on the waters with that at land, and may be called, for the sake of perspicui- ty, a sea-quake; and this also is produced by volcanoes. A spouting up of waters to great heights. It is not easy to describe the manner in which this is performed: but volcanoes also perform the same ; Vesuvius being known frequently to eject a vast body of water. A rocking of the earth to and fro, and sometimes a perpendicular bouncing, if it may be so called, of the same. This differ- rnce chiefly arises from the situation of the place with respect to the suhferranean fire. Directly under, it lifts; at a farther distance, it rocks. Some earthquakes seem to travel onward, and are felt in different countries at different hours the same day. This arises from the great shock being given to the earth at one place, and that being communicated onward T, 36 A HISTORY OF by an undulatory motion, successively affects different regions in its progress ; as the blow given by a stone falling in a lake, is not per- ceived at the shores till some time after the first concussion. The shock is sometimes instantaneous, like the explosion of gunpowder; and sometimes tremulous, and continuing for several minutes. The nearer the place where the shock is first given, the more instantaneous and simple it appears. At a greater distance, the earth redoubles the first blow witli a sort of vibra- tory continuation. As waters have generally so great a share in producing earthquakes, it is not to be wondered that they should generally follow those breaches made by the force of fire, and appear in the great chasms which the earth- quake has opened. These are some of the most remarkable phenomena of earthquakes, presenting a frightful assemblage of the most terrible effects of air, earth, fire, and water. Th'> v.dley ofSolfatara, near Naples, seems to exhibit, in a minuter degree, whatever is seen of this horrible kind oa the great theatre of nature. This plain, which is about twelve hundred feet long, and a thousand broad, is embosomed in mountains, and has in the mid- dle of it a lake of noisome blackish water, covered with a bitumen, that floats upon its surface. In every part of this plain, caverns appear smoking with sulphur, and often emitting flames. The earth, wherever we walk over it, trembles beneath the feet. Noises of flames, and the hissing of waters, are heard at the bottom. The water some- times spouts up eight or ten feet high. The most noisome fumes, fetid water, and sul- phureous vapours, offend the smell. A stone thrown into any of the caverns, is ejected again with considerable violence. These ap- pearances generally prevail when the sea is any way disturbed ; and the whole seems" to exhibit the appearance of an earthquake in miniature. However, in this smaller scene of wonders, as well as in the greater, there are many appearances for which, perhaps, we shall never account ; and many questions may be asked, which no conjectures can thoroughly resolve. It was the fault of the philosophers of the last age, to be more in- quisitive after the causes of things than after the things themselves. They seemed to think that a confession of ignorance can- celled their claims to wisdom ; they, there- fore, had a solution for every demand. But the present age has grown, if not more inquisitive, at least more modest; and none are now ashamed of that ignorance which labour can neither remedy nor re- move. CHAPTER XI. OF THE APPEARANCE OF NEW ISLANDS AND TRACTS; AND OF THE DISAPPEARING OF OTHERS. HITHERTO we have taken a survey only of the evils which are produced by subter- ranean fires, but we have mentioned nothing of the benefits they may possibly produce. They may be of use in warming and cherish- ing the ground, in promoting vegetation, and giving a more exquisite flavour to the pro- ductions of the earth. The imagination of a person who has never been out of our v ovvn mild region, can scarcely reach to that luxu- riant beauty with which all nature appears clothed in those very countries that we hare but just now described as desolated by earth- quakes, and undermined by subterranean fires. It must be granted, therefore, that though in those regions they have a greater share in the dangers, they have also a larger proportion in the benefits of nature. But there is another advantage arising from subterranean fires, which, though hitherto disregarded by man, yet may one day be- come serviceable to him; I mean, that while THE EARTH. they are found to swallow up cities and plains in one place, they are also known to produce promontories and islands in another. We have many instances of islands being thus formed in the midst of the sea, which, though for a long time barren, have afterwards be- come fruitful seats of happiness and industry. New islands are formed in two ways ; ei- ther suddenly, by the action of subterraneous fires; or more slowly, by the deposition of mud, carried down by rivers, and stopped by some accident." With respect particularly to the first, ancient historians, and modern travellers, give us such accounts as we can have no room to doubt of. Seneca assures us, that in his time the island of Therasia ap- peared unexpectedly to some mariners, as they were employed in another pursuit. Pliny assures us, that thirteen islands in the Medi- terranean appeared at once emerging from the water; the cause of which he ascribes rather to the retiring of the sea in those parts, than to any subterraneous elevation. How- ever, he mentions the island of Hiera, near that of Therasia, as formed by subterraneous explosions ; and adds to his list several others formed in the same manner. In one of which he relates that fish in great abundance were found, and that all those who ate of them died shortly after. " On the twenty-fourth of May, b in the year 1707, a slight earthquake was perceived at Santorin; and the day following, at sun- rising, an object was seen by the inhabitants of that island, at two or three miles distance at sea, which appeared like a floating rock. Some persons, desirous either of gain, or in- cited by curiosity, went there, and found, even while they stood upon this rock, that it seemed to rise beneath their feet. They per- ceived also, that its surface was covered with pumice-stones and oysters, which it had rais- ed from the bottom. Every day after, until the fourteenth of June, this rock seemed con- siderably to increase; and then was found to be half a mile round, and about thirty feet above the sea. The earth of which it was composed seemed whitish, with a small pro- portion of clay. Soon after this the sea again a Buffon, vol. ii. p. 343. " Hist, de 1'Acad. an. 1708, p. 23- Justin, lib. xxx. cap. 4. appeared troubled, and steams arose which were very offensive to the inhabitants of San- torin. But on the sixteenth of the succeeding month, seventeen or eighteen rocks more were seen to rise out of the sea, and at length to join together. All this was accompanied with the most terrible noise, and fires which proceeded from the island that was newly formed. The whole mass, however, of all this new-formed earth, uniting, increased every day, both in height and breadth, and, by the force of explosions, cast forth rocks to seven miles distance. This continued to bear the same dreadful appearances till the month of November in the same year; and it is at present a volcano, which sometimes re- news its explosions. It is about three miles in circumference ; and more than from thirty-five to forty feet high." It seems extraordinary, that, about this place in particular, islands have appeared at different times, particularly that of Hiera, mentioned above, which has received con- siderable additions in succeeding ages. Justin tells us, c that at the time the Macedonians were at war with the Romans, a new island appeared between those of Theramenes and Therasia, by means of an earthquake. We are told that this became half as large again about a thousand years after, another island rising up by its side, and joining to it, so as scarcely at present to be distinguished from the former. A new island was formed in the year 1720, near that of Tercera, near the continent of Africa, by the same causes. In the begin- ning of December, at night, there was a ter- rible earthquake at that place, and the top of a new island appeared, which cast forth smoke in vast quantities. The pilot of a ship, who approached it, sounded on one side of this island, and could not find ground at sixty fathom : at tlie other side the sea was totally tinged of a different colour, exhibiting a mix- ture of white, blue, and green; and was very shallow. This island, on its first appearance, larger than it is at present; for it has since that time sunk in such a manner, as to be scarcely above water/ 1 a In the spring of 1783, a volcanic island was formed about 30 miles from the south-west point of Iceland. The I discoverer, Captain Von Lowenhorn, in the Danish service 38 A HISTORY OF A traveller, whom these appearances could not avoid affecting, speaks of them in this manner : a "What can be more surprising than to see fire not only break out of the bow- els of the earth, but also to make itself a pas- sage through the waters of the sea! What can be more extraordinary, or foreign to our common notions of things, than to see the bot- tom of the sea rise up into a mountain above the water, and become so firm an island as to be able to resist the violence of the greatest storms ! I know that subterraneous fires, when pent in a narrow passage, are able to raise up a mass of earth as large as an island : but that this should be done in so regular and ex- act a manner that the water of the sea should not be able to penetrate and extinguish those fires; that after having made so many passa- ges, they should retain force enough to raise the earth ; and, in fine, after having been ex- tinguished, that the mass of earth should not fall down, or sink again with its own weight, but still remain in a manner suspended over the great arch below ! This is what to me seems more surprising than any thing that has been related of Mount J^tna, Vesuvius, or any other volcano." Such are his sentiments : however, there are few of these appearances any way more extraordinary thcin those attending volcanoes arid earthquakes in general. We are not more to be surprised that inflammable substances should be found beneath the bottom of the sea, than at similar depths at land. These have all the force of fire, giving expansion to air, and tending to raise the earth at the bot- tom of the sea, till it at length heaves above water. These marine volcanoes are not so frequent; for, if we may judge of the usual procedure of nature, it must very often hap- pen, that before the bottom of the sea is ele- vated above the surface, a chasm is opened in it, and then the water pressing in, extin- guishes the volcano before it has time to pro- who arrived just at the time of the first eruption, when smoke and flames ascended out of the sea, relates that no island or any land could be seen, from which these flames could originate. No wonder, then, that he fell into the greatest consternation, when, as he expresses himself, he saw the waves on fire. The following year the Danish government directed, that all ships bound to Iceland should examine the new-formed island ; but so entirely duce its effects. This extinction, however, is not effected without very great resistance from the fire beneath. The water, upon dash- ing into the cavern, is very probably at first ejected back with great violence ; and thus some of those amazing water-spouts are seen, which have so often astonished the mariner. j and excited curiosity. But of these in their place. Besides the production of those islands by the action of fire, there are others, as was said, produced by rivers or seas carrying mud, earth, and such like substances, along with their currents; and at last depositing them in some particular place. At the mouths of most great rivers, there are to be seen banks, thus formed by the sand and mud carried down with the stream, which have rested at that place, where the force of the current is diminished by its junction with the sea. These banks, by slow degrees, increase at the bot torn of the deep : the water in those places, is at first found by mariners to grow more shallow ; the bank soon heaves up above the surface ; it is considered, for a while, as a tract of useless and barren sand ; but the seeds of some of the more hardy vegetables are driven thither by the wind, take root, and thus binding the sandy surface, the whole spot is clothed in time with a beautiful ver- dure. In this manner there are delightful and inhabited islands at the mouths of many rivers, particularly the Nile, the Po, the Mis- sissippi, the Ganges, and the Senegal. There has been, in the memory of man, a beautiful and large island formed in this manner at the mouth of the river Nanquin, in China, made from depositions of mud at its opening : it is not less than sixty miles long, and about twenty broad. La Loubere informs us, 1 * in his voyage to Siam, that these sand-banks in- crease every day, at the mouths of all the great rivers in Asia : and hence, he asserts, that the navigation up these rivers becomes had it vanished, that none of them either saw or could discover the smallest trace of it. However, towards the end of the next year, a Danish ship of war, of 64 guns, was wrecked on this rock ; which is now no longer visible, but remains a most dangerous rock, nearly level with the sur- face of the water. a Phil. Trans, vol. v. p. 197- b Lettres Curieuses et Edifiantes, sec. xi. p. 234. THE EARTH. 39 every day more difficult, and will, at one time or other, be totally obstructed. The same may be remarked with regard to the Wolga, which has at present seventy openings into the Caspian sea; and of the Danube, which has seven into the Euxine. We have had an instance of the formation of a new island not very long since at the mouth of the Humber, in England. " It is yet within the memory of man,' r says the relater,* " since it began to raise its head above the ocean. It began its appearance at low water, for the space of a few hours, and was buried again till the next tide's retreat. Thus successively it lived and died, until the year 1666, when it began to maintain its ground against the insult of the waves, and then first invited the aid of human industry. A bank was thrown about its rising grounds, and being thus defended from the incursions of the sea, it became firm and so- lid, and, in a short time, afforded good pas- turage for cattle. It is about nine miles in circumference, and is worth to the proprietor about eight hundred pounds a year. 1 " It would be endless to mention all the islands that have been thus formed, and the advantages that have been derived from them. However, it is frequently found, that new islands may of- ten be considered as only turning the ri- vers from their former beds ; so that in pro- portion as land is gained at one part, it is lost by the overflowing of some other. Little, therefore, is gained by such acces- sion; nor is there much more by the new is- lands which are sometimes formed from the spoils of the continent. Mariners assure us. that there are sometimes whole plains unroot- ed from the main lands, by floods and tem- pests. These being carried out to sea, with all their trees and animals upon them, are frequently seen floating in the ocean, and ex- hibiting a surprising appearance of rural tran- quillity in the midst of danger. The greatest part, however, having the earth at their roots at length washed away, are dispersed, and their animals drowned; but now and then some arc (bund to brave the fury of the ocean, till being stuck either among rocks or sands, 'hoy again take firm footing, and become per- manent islands. 8 Phil Trans, vol. iv. p. 251. As different causes have thus concurred to produce new islands, so we have accounts of others, that the same causes have contributed to destroy. We have already seen the power of earthquakes exerted in sinking whole ci- ties, and leaving lakes in their room. Them have been islands, and regions also, that have shared the same fate ; and have sunk with their inhabitants never more to be heard of Thus Pausanias b tells us of an island called Chryses, that was sunk near Lemnos. Plin; mentions several ; among others, the island of Cea, for thirty miles, having been washed away, with several thousands of its inhabi- tants. But of all the noted devastations of this kind, the total submersion of the island of Atalantis, as mentioned by Plato, has been most the subject of speculation. Mankind, in general, now consider the whole of his de- scription as an ingenious fable ; but when fa- bles are grown famous by time and authority, they become an agreeable, if not a necessary, part of literary information. " About nine thousand years are passed," says Plato, " since the island of Atalantis was in being. The priests of Egypt were well acquainted with it; and the first heroes of Athens gained much glory in their wars with the inhabitants. This island was as large as Asia Minor and Syria united; and was situa- ted beyond the Pillars of Hercules, in the At- lantic ocean. The beauty of the buildings, and the fertility of the soil, were far beyond any thing a modern imagination can conceive: gold and ivory were every where common ; and the fruits of the earth offered themselves without cultivation. The arts and the courage of the inhabitants, were not interior to the happiness of their situation; and they were frequently known to make conquests, and overrun the continents of Europe and Asia.'' The imagination of the poetical philosopher riots in the description of the natural and ac- quired advantages, which they long enjoyed in this charming region. " If," says he, " we compare that country to our own, ours will appear a mere wasted skeleton, when oppo- sed to it. Their mountains, to the very tops, were clothed with fertility, and poured down rivers to enrich the plains below/' b Pausanias, 1. 8. in Arcad. p. 509- ' Plato in Critia. M 40 A HISTORY OF However, all these beauties and benefits were destroyed in one day by an earthquake sinking the earth, and the sea overwhelming it. At present not the smallest vestiges of such an island are to be found ; Plato remains as the only authority for its existence ; and phi- losophers dispute about its situation. It is not for me to enter into the controversy, when there appears but little probability to support the fact; and, indeed, it would be useless to run back nine thousand years in search of difficulties, as we are surrounded with objects that more closely affect us, and that de- mand admiration at our very doors. When I consider, as Lactantius suggests, the va- rious vicissitudes of nature ; lands swal- lowed by yawning earthquakes, or over- whelmed in the deep; rivers and lakes disappearing, or dried away; mountains le- velled into plains ; and plains swelling up into mountains; I cannot help regarding this earth as a place of every little stability; as a transient abode of still more transitory beings. CHAPTER XH. OF MOUNTAINS. HAVING at last, in some measure, emerg- ed from the deeps of the earth, we come to a scene of greater splendour; the contempla- tion of its external appearance. In this sur- vey, its mountains are the first objects that strike the imagination, and excite our curio- sity. There is not, perhaps, any thing in all nature that impresses an unaccustomed spec- tator with such ideas of awful solemnity, as these immense piles of Nature's erecting, that seem to mock the minuteness of human mag- nificence. In countries where there are nothing but plains, the smallest elevations are apt to ex- cite wonder. In Holland, which is all a fiat, they show a little ridge of hills, near the sea- side, which Boerhaave generally marked out to his pupils, as being mountains of no small consideration. What would be the sensations of such an auditory, could they at once be presented with a view of the heights and pre- cipices of the Alps or the Andes ! Even among us in England, we have no adequate' ideas of a mountain prospect; our hills are generally sloping from the plain, and clothed to the very top with verdure : we can scarce- ly, therefore, lift our iin-.ginations to those immense piles, whose tops peep up behind intervening clouds, sharp and precipitate, and reach to heights thit human avarice or curio- sity have never been able to ascend. We, in this part of the world, are not, for that reason, so immediately interested in the question which has so long been agitated among philosophers, concerning what gave rise to these inequalities on the surface of the globe. In our own happy region, we gene- rally see no inequalities but such as contri- bute to use and beauty; and we therefore are amazed at a question, inquiring how such necessary inequalities came to be formed, and seeming to express a wonder how the globe comes to be so beautiful as we find it But though with us there may be no great cause for such a demand, yet in those places where mountains deform the face of nature, where they pour down cataracts, or give fury to tempests, there seems to be good reason for inquiry either into their causes or their uses. It has been, therefore, asked by many, in what manner mountains have come to be formed ; or for what uses they are designed ? To satisfy curiosity in these respects, much reasoning has been employed, and very little knowledge propagated. With regard to the first part of the demand, the manner in which mountains were formed, we have already seen the conjectures of different philosophers on that head. One supposing that they were formed from the earth 1 ? iiroken shell at the time of the deluge ; another, that they exist- ed from the creation, and only acquired their THE EARTH. 41 deformities in process of time ; a third, that they owed their original to earthquakes ; and still a fourth, with much more plausibility than the rest, ascribing them entirely to the fluc- tuations of the deep, which he supposes in the beginning to have covered the whole earth. Such as are pleased with disquisitions of this kind, may consult Burnet, Winston, Woodward, or Buffon. Nor would I be thought to decry any mental amusements, that at worst keep us innocently employed ; but, for my own part, I cannot help wondering how the opposite demand has never come to be made ; and why philosophers have never asked how we come to have plains? Plains are sometimes more prejudicial to man than mountains. Upon plains, an inundation has greater power; the beams of the sun are often collected there with suffocating fierceness; they are sometimes found desert for several hundred miles together, as in the country east of the Caspian sea, although otherwise fruit- ful, merely because there are no risings or depressions to form reservoirs, or collect the smallest rivulet of water. The most rational answer, therefore, why either mountains or plains were formed, seems to be that they were thus fashioned by the hand of Wisdom, in order that pain and pleasure should be so contiguous, as that morality might be exer- cised either in bearing the one, or communi- cating the other. Indeed, the more I consider this dispute respecting the formation of mountains, the more I am struck with the futility of the ques- tion. There is neither a straight line, nor an exact superficies, in all nature. If we con- sider a circle, even with mathematical pre- cision, we shall find it formed of a number of small right lines, joining at angles together. These angles, therefore, may be considered in a circle as mountains are upon our globe ; and to demand the reason for the one being mountainous, or the other angular, is only to ask, why a circle is a circle, or a globe is a globe. In short, if there be no surface with- out inequality in nature, why should we be surprised that the earth has such ? It has often been said, that the inequalities of its surface are scarce distinguishable, if compared to its magnitude; and ! think we have every reason to be content with the answer. Some, however, have avoided the difficulty by urging the final cause. They allege, that mountains have been formed merely because they are useful to man. This carries the in- quirer but a part of the way ; for no one can affirm, that in all places they are useful. The contrary is known, by horrid experience, in those valleys that are subject to their in- fluence. However, as the utility of any part of our earthly habitation is a very pleasing and flattering speculation to every philoso- pher, it is not to be wondered that much has been said to prove the usefulness of these. For this purpose many conjectures have been made, that have received a degree of assent even beyond their evidence; for men were unwilling to become more miserably wise. It has been alleged, as one principal ad- vantage that we derive from them, that they serve, like hoops or ribs, to strengthen our earth, and to bind it together. In conse- quence of this theory, Kircher has given us a map of the earth, in this manner hooped with its mountains ; which might have a much more solid foundation, did it entirely corres- pond with truth. Others haVe found a different use for them. ! especially when they run surrounding our globe ; which is, that they stop the vapours which are continually travelling from the equator to the poles ; for these being urged by the heat of the sun, from the warm regions of the line, must all be accumulated at the poles, if they were not stopped in their way by those high ridges of mountains which cross their direction. But an answer to this may be, that all the great mountains in America lie lengthwise, and therefore do not cross their direction. But to leave these remote advantages, others assert, that not only the animal but vegetable part of the creation would perish for want of convenient humidity, were it not for their friendly assistance. Their summits are, by these, supposed to arrest, as it were, the vapours which float in the regions of the 'heir large inflections and channels are air. considered as so many basons prepared for the reception of those thick vapours, and im- petuous rains, which descend into them. The huge caverns beneath are so many magazines or conservatories of water for the peculiar 42 A HISTORY OF e of man ; and those orifices by which Ihe water is discharged upon the plain, are so situated as to enrich and render them fruitful, instead of returning through subter- raneous channels to the sea, after the perform- ance of a tedious and fruitless circulation. 3 However this be, certain it is, that almost all our great rivers find their source among mountains ; and, in general, the more exten- sive the mountain, the greater the river: thus the river Amazon, the greatest in the world, has its source among the Andes, which are the highest mountains on the globe ; the ri- ver Niger travels a long course of several hundred miles from the mountains of the Moon, the highest in all Africa; and the Da- nube and the Rhine proceed from the Alps, which are probably the highest mountains of Europe. It needs scarcely be said, that, with respect to height, there are many sizes of mountains, from the gently rising upland, to the tall crag- y precipice. The appearance is in general ifferent in those of different magnitudes. The first are clothed with verdure to the very tops, and only seem to ascend to improve our pros- pects, or supply us with a purer air : but the lofty mountains of the oilier class have a very different aspect. At a distance their tops are seen, in wavy ridges, of the very colour of the clouds, and only to be distinguished from them by their figure; which, as I have said, resembles the billows of the sea. b As we ap- proach, the mountain assumes a deeper co- lour ; it gathers upon the sky, and seems to hide half the horizon behind it. Its summits also are become more distinct, and appear with a broken and perpendicular line. What at first seemed a single hill, is now found to be a chain of continued mountains, whose tops running along in ridges, are embosomed in each other; so that the curvatures of one are fitted to the prominences of the opposite side, and form a winding valley between, of- ten of several miles in extent ; and all the way continuing nearly of the same breadth. Nothing can be finer, or more exact, than Mr. Pope's description of a traveller stniining tip the Alps. Every mountain he comes to a Nature Displayed, vol. iii. p. 88. h Lettres 1'hiloFophiques sur la Formation, & r r. p. IOC. he thinks will be the last; he finds, however, an unexpected hill rise before him ; and thaf being scaled, he finds the highest summit al- most at as great a distance as before. Upon quitting the plain, he might have left a green and fertile soil, and a climate warm and pleas- ing. As he ascends, the ground assumes a more russet colour; the grass becomes more mossy, and the weather more moderate. Still as he ascends, the weather becomes more cold, and the earth more barren. In this dreary passage he is often entertained with a little valley of surprising verdure, caused by the reflected heat of the sun collected into a nar- row spot on the surrounding heights. But it much more frequently happens that he sees only frightful precipices beneath, and lakes of amazing depths; from whence rivers are formed, and fountains derive their original. On those places next the highest summits, vegetation is scarcely carried on ; here and there a few plants of the most hardy kind ap- pear. The air is intolerably cold ; either continually refrigerated with frosts, or dis- turbed with tempests. All the ground here wears an eternal covering of ice, and snows that seem constantly accumulating. Upon emerging from this war of the elements, he ascends into a purer and serener region, where vegetation is entirely ceased ; where the precipices, composed entirely of rocks, rise perpendicularly above him ; while he views beneath him all the combat of the ele- ments; clouds at his feet, and thunders dart- ing upwards from their bosoms below." A thousand meteors, which are never seen on the plain, present themselves. Circular rain- bows;* 1 mock suns; the shadow of the moun- tain projected upon the body of the air : e and the traveller's own image, reflected as in a looking-glass, upon the opposite cloud/ Such are, in general, the wonders that pre- sent themselves to a traveller in bis journey either over the Alps or the Andes. But we must not suppose that this picture exhibits either a constant or an invariable likeness of those stupendous heights. Indeed, nothing can be more capricious or irregular than the forms of many of them. The tops of some Ulloa. vol. i. d Ibid. Phil. Trans, vol. v. p. 152. f Ulloa, vol. i. THE EARTH. 43 run in ridges for a considerable length, without interruption ; in others, the line seems indented by great valleys to an amazing depth. Sometimes a solitary and a single mountain rises from the bosom of the plain ; and sometimes extensive plains, and even provinces, as those of Savoy and Quito, are found embosomed near tops of mountains. In general, however, those countricsthat are most mountainous, are the most barren and uninhabitable. If we compare the heights of mountains with each other, we shall lind that the great- est and highest are found under the line." It is thought by some, that the rapidity of the earth's motion in these parts, together with the greatness of the tides there, may have thrown >up those stupendous masses of earth. But, be the cause as it may, it is a remarka- ble fact, that the inequalities of the earth's surface are greatest there. Near the poles, the earth, indeed, is craggy and uneven enough; but the heights of the mountains there are very inconsiderable. On the con- trary, at the equator, where nature seems to sport in the amazing size of all her produc- tions, the plains are extensive, and the moun- tains remarkably lofty. Some of them are known to rise three miles perpendicular above the bed of the ocean. To enumerate the most remarkable of these, according to their size, we shall begin with the Andes, of which we have an excellent de- scription by Ulloa, who wont thither by com- mand of the king of Spain, in company with the French Academicians, to measure a de- gree of the meridian. His journey up these mountains is too curious not to give an ex- tract from it. After many incommodious days sailing up the river Guayaquil, he arrived at Caracol, a town situated at the foot of the Andes. No- thing could exceed the inconveniences which ho experienced in this voyage, from the flies and moschotoes, (an animal resembling our gnat.) " We were the whole day," says he, " in continual motion to keep them off; but at night our torments were excessive. Our gloves, indeed, were some defence to our hands; but our faces were entirely exposed; Kuftbn, passim. NO. 5. nor were our clothes a sufficient defence for the rest of our bodies ; for their stings pene- trating through the cloth, caused a very pain- ful and fiery itching. One night, in coming to an anchor near a large and handsome house that was uninhabited, we had no sooner seat- ed ourselves in it, than we were attacked on all sides by swarms of moschetoes, so that it was impossible to have one moment's quiet. Those who had covered themselves with clothes made for this purpose, found not the smallest defence ; wherefore, hoping to find some relief in the open fields, we ventured out, though in danger of suffering in a more terrible manner from the serpents. But both places were equally obnoxious. On quitting this inhospitable retreat, we the next night took up our quarters in a house that was in- habited ; the host of which being informed of the terrible manner we had past the night bc- fore, gravely told us, that the house we so greatly complained of, had been forsaken on account of its being the purgatory of a soul. But we had more reason to believe that it was quitted on account of its being the pur- gatory of the body. After having journeyed for upwards of three days, through boggy roads, in which the mules at every step sunk up to their bellies, we began at length to per- ceive an alteration in the climate; and hav- ing been long accustomed to heat, we now began to feel it grow sensibly colder. " It is remarkable, that at Tariguagua we often see instances of the effects of two op- posite temperatures, in two persons happen- ing to meet; one of them leaving the plains below, and the other descending from the mountain. The former thinks the cold so se- vere, that he wraps himself up in all the gar- ments he can procure ; while the latter finds the heat so great, that he is scarce able to bear any clothes whatsoever. The one thinks the water so cold, that he avoids being sprink- led by it; the ofher is so delighted with its warmth, that he uses it as a bath. Nor is the ease very different in the same person, who experiences the same diversity of sensation upon his journey up, and upon his return. This difference only proceeds from the change naturally felt at leaving a climate to which one has been accustomed, and coming into another of an opposite tempeniture. N 44 A HISTORY OF ; The ruggedness of the road from Tarigu- agua, leading up the mountain, is not easily described. In some parts, the declivity is so great, that the mules can scarcely keep their tooting; and in others, the acclivity is equally difficult. The trouble of having people going before to mend the road, the pains arising from the many falls and bruises, and the being constantly wet to the skin, might be support- ed, were not these inconveniences augmented by the sight of such frightful precipices, and deep abysses, as must fill the mind with ceaseless terror. There are some places where the road is so steep, and yet so nar- roAV, that the mules are obliged to slide down, without making any use of their feet whatso- ever. On one side of the rider, in this situa- tion, rises an eminence of several hundred yards ; and on the other, an abyss of equal depth ; so that if he in the least checks his mule, so as to destroy the equilibrium, they both must unavoidably perish. " After having travelled about nine days in this manner, slowly winding along the side of the mountain, we began to find the whole country covered with an hoar frost; and an hut, in which we lay, had ice on it. Having escaped many perils, we at length, after a journey of fifteen days, arrived upon the plain, on the extremity of which stand* the city of Quito, the capital of one of the most charming regions upon earth. Here, in the centre of the torrid zone, the heat is not only very tolerable, but in some places the cold also is painful. Here they enjoy all the temperature and advantages of perpetual spring; their fields being always covered with verdure, and enamelled with flowers of the most lively co- lours. However, although this beautiful re- gion be higher than any other country in the world, and although it took up so many days of painful journey in the ascent, it is still overlooked by tremendous mountains ; their sides covered with snow, and yet flaming with volcanoes at the top. These seemed piled one upon the other, and rise to a most astonishing height, with great coldness. How- ever, at a determined point above the surface of the sea, the congelation is found at the same height in all the mountains. Those parts which are not subject to a continual frost, have here and there growing upon them a rush, resembling the genista, but much more soft and flexible. Towards the extremity of the part where the rush grows, and the cold begins to increase, is found a vegetable, with a round bulbous head, which, when dried, becomes of amazing elasticity. Higher up, the earth is entirely bare of vegetation, and seems covered with eternal snow. The most remarkable mountains are, that of Co- topaxi, (already described as a volcano,) Chimborazo, and Pinchincha. Colopaxi is more than three geographical miles above the surface of the sea: the rest are not much inferior. On the top of the latter was my station for measuring a degree of the meri- dian; where I suffered particular hardships, from the intenseness of the cold, and the vio- lence of the storms. The sky round was, in general, involved in thick fogs, which, when they cleared away, and the clouds, by their gravity, moved nearer to the suriace of the earth, they appeared surrounding the loot of the mountain, at a vast distance below, like a sea, encompassing an island in the midst of it. When this happened, the horrid noises of tempests were heard from beneath, then dis- charging themselves on Quito, and the neigh- bouring country. I saw the lightnings issue from the clouds, and heard the thunders roll far beneath me. All this time, vshile the tem- pest was raging below, the mountain top, where I was placed, enjoyed a delightful se- renity; the wind was abated; the sky clear; and the enlivening rays of the sun moderated the severity of the cold. However, this was of no very long duration, for the wind returned with all its violence, and with such velocity as to dazzle the sight; whilst my fears were increased by the dreadful concussions of the precipice, and the fall of enormous rocks ; the only sounds that were heard in this fright- ful situation." Such is the animated picture of those moun tains, as given us by this ingenious Spaniard : and I believe the reader will wish that 1 had made the quotation still longer. A passage over the Alps, or a journey across the Pyre- nees, appear petty trips or excursions in the comparison; and yet these are the most lofty mountains we know of in Europe. If we compare the Alps with the mountains already described, we shall find them but lit- THE EARTH. tie more than one half of the height of the former. The Andes, upon being measured by the barometer, are found above three thousand one hundred and thirty-six toises or fathoms above the surface of the sea." Whereas the highest point of the Alps is not above sixteen hundred. The one, in other words, is above three miles high ; the other about a mile and a half. The highest mountains in Asia are Mount Taurus, Mount Immaus, Mount Caucasus, and the mountains of Japan. Of these, none equals the Andes in height ; although Mount Caucasus, which is the highest of them, makes very near ap- proaches. Father Verbiest tells of a moun- tain in China, which he measured, and found a mile and a half high. b In Africa, the moun- tains of the Moon, famous for giving source to the Niger and the Nile, are rather more noted than known. Of the Peak of Teneriffe, one of the Canary Islands that lie off this coast, we have more certain information. In the year 1727, it was visited by a company of English merchants, who travelled up to the top, where they observed its height, and the volcano on its very summit. They found it a heap of mountains, the highest of which ri- ses over the rest like a sugar-loaf, and gives a name to the whole mass. It is computed to be a mile and a half perpendicular from the surface of the sea. Kircher gives us an esti- mate of the heights of most of the other great mountains in the world; but as he has taken his calculations in general from the ancients, or from modern travellers, who had not the art of measuring them, they are quite incredi- ble. The art of taking the heights of places by the barometer, is a new and ingenious in- vention. As the air grows lighter as we as- cend, the fluid in the tube rises in due pro- portion : thus the instrument being properly marked, gives the height with a tolerable de- gree of exactness ; at least enough to satisfy curiosity. Few of our great mountains have been es- timated in this manner; travellers having, perhaps, been deterred, by a supposed im- possibility of breathing at the top. However, it has been invariably found, that the air in the highest that our modern travellers have Ulloa, vol. i. p. 442 ascended, is not at all too fine for respiration. At the top of the Peak of Teneriffe, there was found no other inconvenience from the air, except its coldness ; at the top of the Andes, there was no difficulty of brea tiling perceived. The accounts, therefore, of those w^ho have asserted that they were unable to breathe, although at much less heights, are greatly to be suspected. In fact, it is very natural for mankind to paint those obstacles as insur- mountable, which they themselves have not had the fortitude or perseverance to sur- mount. The difficulty and danger of ascending to the tops of mountains, proceeds from other causes, not the thinness of the air. For in- stance, some of the summits of the Alps have never yet been visited by man. But the rea- son is, that they rise with such a rugged and precipitate ascent, that they are utterly inac- cessible. In some places they appear like a great wall of six or seven hundred feel high ; in others, there stick out enormous rocks, that hang upon the brow of the steep, and every moment threaten destruction to the traveller below. In this manner almost all the tops of the highest mountains are bare and pointed. And this naturally proceeds from their being so continually assaulted by thunders and tem- pests. All the earthy substances with which they might have been once covered, have for ages been washed away from their summits ; and nothing is left remaining but immense rocks, which no tempest has hitherto been able to destroy. Nevertheless, time is every day, and every hour, making depredations; and huge frag- ments are seen tumbling down the precipice, either loosened from the summit by frost or rains, or struck down by lightning. Nothing can exhibit a more terrible picture than one of these enormous rocks, commonly larger than a house, falling from its height, with a noise louder than thunder, and rolling down the side of the mountain. Doctor Plot tells us of one in particular, which being loosened from its bed, tumbled down the precipice, and was partly shattered into a thousand pieces. Notwithstanding, one of the largest frag- b Verbiest, a la Chine. c Phil. Trans, vol. \. 46 A HISTORY OF ments of the same, still preserving its motion, 'travelled over the plain below, crossed a ri- vulet in the midst, and at last stopped on the other side of the bank ! These fragments, as was said, arc often struck offby lightning, and sometimes undermined by rains ; but the most usual manner in which they are disunited from the mountain, is by frost : the rains insinua- ting between the interstices of the mountain, continue there until there comes a frost, and then, when converted into ice, the water swells with an irresistible force, and produces the same effect as gunpowder, splitting the most solid rocks, and thus shattering the summits of the mountain. But not rocks alone, but whole mountains are, by various causes, disunited from each other. We see in many parts of the Alps, amazing clefts, the sides of which so exactly correspond with the opposite, that no doubt can be made of their having been once joined together. At Cajeta," in Italy, a mountain was split in this manner by an earthquake ; and there is a passage opened through it, that ap- pears as if elaborately done by the industry of man. In the Andes these breaches are frequently seen. That at Thermopyle, in Greece, has been long famous. The mountain of the Troglodytes, in Arabia, .has thus a pas- sage through it : and that in Savoy, which na- ture began, and which Victor Amadeus com- pleted, is an instance of the same kind. We have accounts of some of these disrup- tions, immediately after their happening. " In the month of June, b in the year 1714, a part of the mountain of Diableret, in the district of Valais, in France, suddenly fell down between two and three o'clock in the afternoon, the Aveather being very calm and serene. It was of a conical figure, and destroyed fifty- five cottages in the fall. Fifteen persons, to- gether with about a hundred beasts, were also crushed beneath its ruins, which cover- ed an extent of a good league square. The dust it occasioned instantly covered all the neighbourhood in darkness. The heaps of rubbish were more than three hundred feet high. They stopped the current of a river that ran along the plain, which is now form- ed into several new and deep lakes. There " Burton, vol. ii. p. 364. appeared, through the whole of this rubbish, none of those substances that seemed to indi- cate that this disruption had been by means of subterraneous fires. Most probably, the base of this rocky mountain was rotted and decayed ; and thus fell, without any extrane- ous violence." In the same manner, in the year 1018, the town ofPleurs, in France, v>as buried beneath a rocky mountain, at the ion) of which it was situated. These accidents, and many more that might be enumerated of the same kind, have been produced by various causes; by earthquakes, as in the mountain at Cajeta; or by being de- cayed at the bottom, as at Diableret. But the most general way is, by the foundation of one part of the mountain being hollowed by waters, and thus wanting a support, breaking from the other. Thus it generally has been found in the great chasms in the Alps; and thus it almost always is known in those dis- ruptions of hills, which are known by the name of land-slips. These are nothing more than the slidings down of a higher piece- of ground, disrooted from its situation by sub- terraneous inundations, and settling itself upon the plain below. There is not an appearance in all nature that so much astonished our ancestors, as these land-slips. In fact, to behold a large upland with its houses, its corn, and cattle,"at once loosened from its place, and iloating, as it were, upon the subjacent water ; to behold it quitting its ancient situation, and travelling forward like a ship in quest of new adven- tures; this is certainly one of the most extra- ordinary appearances that can be imagined; and (o a people, ignorant of the powers of na- ture, might well be considered as a prodigy. Accordingly, we find all our old historians mentioning it as an omen of approaching ca- lamities. In this more enlightened age. how- ever, its cause is very well known; and, in- stead of exciting ominous apprehensions in the populace, it only gives rise to some very ridiculous law-suits among them, about whose the property shall be; whether the land which has thus slipt shall belong to the origi- nal possessor, or to him upon whose grounds it has encroached and settled. What has b Hist, de 1'Academie dcs Sciences, p. 4. an. 1715. THE EARTH. ',7 been the determination of the judges, is not so well known, but the circumstances of the slips have been minutely and: exactly de- scribed. In the lands of Slatberg, a in the kingdom of Iceland, there stood a declivity, gradually ascending for near half a mile. In the year ,1713, and on the 10th of March, the inhabi- tants perceived a crack on its side, somewhat like a furrow made with a plough, which they imputed to the effects of lightning, as there had been thunder the night before. How- e\er, on the evening of the same day, they were surprised to hear an hideous confused noise issuing all round from the side of the hill; and their curiosity being raised, they resorted to the place. There, to their amaze- ment, they found the earth, for near five acres, all in gentle motion, and sliding down the hill upon the subjacent plain. This motion con- tinued the remaining part of the day, and the whole night Aor did the noise cease, during the whole time ; proceeding, probably, from the attrition of the ground beneath. The day following, however, this stras-ge journey down the hill ceased entirely; and above an acre of the meadow below was found covered whut before composed a part of the de- clivity. i lowevcr, these slips, when a whole moun- tain's side seems to descend, happen but very rar.-ly. There are some of another kind, ever, much more co;n;:ion; and, as they are always sudden, much more dangerous. These are snow-slips, well known, and great- ly dreaded by travellers. It often happens, that when snow has long been accumulated on the tops and on the sides of mountains, it is borne down the precipice, either by means of tempests, or its own m-'-Hing. At first, when loosened, the volume in motion is but small ; but gathers as it continues to roll ; and, by the time it has reached the habitabfc parts of the mountain, is generally grown of enormous bulk. Wherever it rolls, it levels all things Phil. TYaus. vol. iv. p. U30. in its way; or buries them in unavoidable destruction. Instead of rolling, it someti;ne> is found to slide along from the top; yet e\e i thus it is generally as fatal as before. Never- theless, we have had an instance, a few years ago, of a small family in Germany, that lived for above a fortnight beneath one of these snow-slips. Although they were buried, du- ring that whole time, in utter darkness, and under a bed of some hundred feet deep, yet they were luckily taken out alive; the weight of the snow being supported by a beam that kept up the roof; and nourishment being sup- plied them by the milk of an ass, if I remem- ber right, that was buried under the same ruin. But it is not the parts alone that are^ thus found to subside, whole mountains have been known totally to disappear. Pliny tells us, b that in his own time the lofty mountain of Cybotus, together with the city of Eurites, were swallowed by aa earthquake. The same fate, he says, attended Phlegium, one of the highest mountains in Ethiopia; which, after one night's concussion, was never seen more. In more modern times, a very noted moun- tain in the Molucca islands, known by the name of the Peak, and remarkable for being seen at a very great distance from sea, was swallowed by an earthquake; and nothing but a lake was left in the place where it stood. Thus, while storms arid tempests are levelled against mountains above, earthquakes and waters are undermining them below. All our histories talk of their destruction ; and very few new ones (if we except mount Cenere. and one or two such heaps of cinders,) arc produ- ced. If mountains, therefore, were of such great utility, as some philosophers make them, to mankind, it would be. a very melancholy con- sideration that such benefits were diminishing every day. But the truth is, the valleys are fertilized by that earth which is washed from their sides; and (he plains become richer, in proportion as the mountains decay. b Plin. lib. ii. cap. P. : J. 48 A HISTORY OP CHAPTER XIII. OF WATER. IN contemplating nature, we shall often find the same substances possessed of contrary qualities, and producing opposite effects. Air, which liquefies one substance, dries up ano- ther. That fire which is seen to burn up the desert, is often found, in other places, to assist the luxuriance of vegetation; and water, which, next to fire, is the most fluid substance upon earth, nevertheless gives all other bo- dies their firmness and durability ; so that every element seems to be a powerful servant, capable either of good or ill, and only await- ing external direction, to become the friend or the enemy of mankind. These opposite qualities, in this substance in particular, have not failed to excite the admiration and inquiry of the curious. That water is the most fluid penetrating body, next to fire, and the most difficult to confine, is incontestably proved by a vari- ety of experiments. A vessel through which water cannot pass, may be said to retain any thing. It may be objected, indeed, that syrups, oils, and honey, leak through some vessels that water cannot pass through ; but this is far from facing the result of the greater tenuity and fineness of their parts ; it is owing to the rosin wherewith the wood of such vessels abounds, which oils and syrups have a power of dissolving; so that these fluids, instead of finding their way, may more properly be said to eat their way through the vessels that con- tain them. However, water will at last find its way even through these ; for it is known to ascape through vessels of every substance, glass only excepted. Other bodies may be ifound to make their way out more readily in- deed ; as air, when it finds a vent, will escape at once; and quicksilver, because of its weight, quickly penetrates through whatever chinky vessel confines it : but water, though it oper- ates more slowly, yet always finds a more cer- tain issue. As, for instance, it. is well known that air will not pass through leather ; which water will very readily penetrate. Air also may be retained in a bladder; but water will quickly ooze through. And those who drive this to the greatest degree of precision, pre- tend to say, that it will pass through pores ten times smaller than air can do. Be this as it may, we are very certain that its parts are so small that they have been actually driven through the pores of gold. This has been proved by the famous Florentine experiment, in which a quantity of water was shut up in a hollow ball of gold, and then pressed with a huge force by screws, during which the fluid was seen to ooze out through the pores of the metal, and to stand, like a dew, upon its sur- face. As water is thus penetrating, and its parts thus minute, it may easily be supposed that they enter into the composition of all bodies, vegetable, animal, and fossil. This every chy- mist's experience convinces him of; and the mixture is the more obvious, as it can always be separated, by a gentle heat, from those substances with which it had been united. Fire, as was said, will penetrate where water cannot pass ; but then it is not so easily to be separated. But there is scarce any substance from which its water cannot be divorced. The parings or filings of lead, tin, and antimo- ny, by distillation, yield water plentifully : the hardest stones, sea-salt, nitre, vitriol, and sul- phur, are found to consist chiefly of water; into which they resolve by force of fire. "All birds, beasts, and fishes," says Newton, " in- sects, trees, and vegetables, with their parts, grow from water ; and, by putrefaction, return to water again." In short, almost every sub- stance that we see, owes its texture and firm- ness to the parts of water that mix with its earth ; and, deprived of this fluid, it becomes a mass of shapeless dust and ashes. From hence we see, as was above hinted, that this most fluid body, when mixed with others, gives them consistence and form. Wa- ter, by being mixed with earth or ashes, and formed into a vessel, when baked before the THE EARTH. 49 fire, becomes a coppel, remarkable for this, that it will bear the utmost force of the hot- test furnace that art can contrive. So the Chinese earth, of which porcelain is made, is nothing more than an artificial composition of earth and water, united by heat; and which a greater degree of heat could easily separate. Tli us we see a body, extremely fluid of it- self, in some measure assuming a new nature, l>y being united with others : we see a body, whose fluid and dissolving qualities are so ob- * ious, giving consistence and hardness to all ihe substances of the earth. From considerations of this kind, Thales, and many of the ancient philosophers, held that all things were made of water. In order to confirm this opinion, Helmont made an ex- periment, by divesting a quantity of earth of all its oils and salts, and then putting this earth, so prepared, into an earthen pot, which nothing but rain-water could enter, and plant- ing a willow therein ; this vegetable, so plant- ed, grew up to a considerable height and bulk, merely from the accidental aspersion of rain-water; while the earth, in which it v/as planted, received no sensible diminution. From this experiment, he concluded, that water was the only nourishment of the vege- table tribe; and that vegetables, being the nourishment of animals, all organized sub- stances, therefore, owed their support and being only to water. But this has been said by Woodward to be a mistake: for he shows, that water being impregnated with earthy particles, is only the conveyer of such substan- ces into the pores of vegetables, rather than an increaser of them by its own bulk : and likewise, that water is ever found to afford so much less nourishment, in proportion as it is purified by distillation. A plant in distil- led water will not grow so fast as in water not dis'.illed: and if the same be distilled three or four times over, the plant will scarcely grow ut all, or receive any nourishment 1'rom it. So that water, as such, does not seem the proper nourishment of vegetables, but only the vehi- cle thereof, which contains the nutritious par- ticles, and carries them through all parts of Hill's History of Fossils. '' Hermetically sealing a glass vessel, means no more tlian beating the mouth of the phial red hot ; and thus, the plant. Water, in its pure state, may suf- fice to extend or swell the parts of a plant, but affords vegetable matter in a moderate proportion. However this be, it is agreed on all sides, that water, such as we find it, is far from being a pure simple substance. The most genuine we know is mixed with exhalations and disso- lutions of various kinds ; and no expedient that has been hitherto discovered, is capable of purifying it entirely. If we filter and distil it a thousand times, according to Boerhaave, it will still depose a sediment : and by repeat- ing the process we may evaporate it entirely away, but can never totally remove its impu- rities. Some, however, assert, that water, properly distilled, will have no sediment ; a and that the little white speck which is found at the bottom of the still, is a substance that en- ters from without. Kircher used to show in his Museum, a phiai of water, that had been kept for fifty years, hermetically sealed ; b du- ring which it had deposed no sediment, but continued as transparent as when first it was put in. How far, therefore, it may be brought to a state of purity by distillation, is unknown; but we very well know, that all such water as we every where see, is a bed in which plants, minerals, and animals, are all found confusedly floating together. Rain-water, which is a fluid of Nature's own distilling, and which has been raised so high by evaporation, is nevertheless a very mixed and impure substance. Exhalations of all kinds, whether salts, sulphurs, or metals, make a part of its substance, and tend to increase its weight. If we gather the water that falls, after a thunder-clap, in a sultry summers day, and let it settle, we shall find a real salt stick- ing at the bottom. In winter, however, its impure mixtures are fewer, but still may be separated by distillation. But as to that which is generally caught pouring from the tops of houses, it is particularly foul, being impreg- nated with the smoke ol the chimneys, the va- pour of the slates or tiles, and with other im- purities that birds and animals may have de- posited there. Besides, though it should be when the glass is become pliant, squeezing the mouth to- gether with a pair of pincers, and then twisting it six or seven times round, 'vhich effectually closes it up. A HISTORY OF supposed live iVoin all these, it is mixed with u quantityof air, which, after being kept for some time, will be seen to separate. Spring-water is next in point of purity. This, according to Dr. Halley, is collected from the air itself; which being sated with ^yater, and coming to be condensed by the evening's cold, is driven against the tops of the mountains, where being condensed and collected, it trickles down by the sides, into the cavities of the earth ; and running for a while under- ground,bubbles up in fountains upon the plain. This having made but a short circulation, has generally had no long time to dissolve or im- bibe any foreign substances by the way. River-water is generally more foul than the former. Wherever the stream flows, it re- ceives a tincture from its channel. Plants, minerals, and animals, all contribute to add to its impurities : so that such as live at the mouths of great rivers, are generally subject to all those disorders which contaminated and unwholesome waters are known to produce. Of all the river-water in the world, that of the Indus and the Thames is said to be the most light and wholesome. The most impure fresh water that we know, is that of stagnating pools and lakes, * Inch, in summer, may be more properly considered as a jelly of floating insects, than a collection of water. In this, millions of little reptiles, undisturbed by any current, which might crush their frames to pieces, breed and engender. The whole teems with shapeless life, and only grows more fruitful by increasing putre- faction. Of the purity of all these waters, the light- ness, and not the transparency, ought f o be the test. Water may be extremely ck a.r and beautiful to the eye, and yet very much im- pregnated with mineral particles. In fact, sea-water is the most transparent of any, and yet it is well known to contain a large mix- ture of salt and bitumen. On the contrary, those waters which are lightest, have the few- est dissolutions floating in them ; and may, therefore, be the most useful for all the pur- poses of life. But, after all, though much has been said upon this subject, and although wa- ters have been weighed with great assiduity, to determine their degree of salubrity, yet neither this, nor their curdling with soap, nor any other philosophical standard whatsoever, will answer the purposes of true information. Experience alone ought to determine the use- ful or noxious qualities of every spring ; and | experience assures us, that different kinds of 1 water are adopted to different constitutions. I An incontestable proof of this, are the many i medicinal springs throughout the world, whose i peculiar benefits are known to the natives of their respective countries. These are of va- rious kinds, according to the different miner- als with which they are impregnated ; hot, saline, sulphureous, bituminous, and oily. But the account of these will come most properly under that of the several minerals by which they are produced. After all, therefore, we must be contented with but an impure mixture for our daily be- verage. And yet, perhaps, this very mixture may often be more serviceable to our health than that of a purer kind. We know that it is so with regard to vegetables : and why not, also, in general, to man ? Be this as it will, if we are desirous of having water in its greatest purity, we are ordered, by the curious in this particular, to distil it from snow, gathered upon the tops of the highest mountains, and to take none but the outer and superficial part thereof. This we must be satisfied to call pure water; but even this is far short of the pure unmixed philosophical element ; which, in reality, is no where to be found. As water is thus mixed with foreign matter, and often the repository of minute animals, or vegetable seeds, we need not be surprised that, when carried to sea, it is always found to putrefy. But we must not suppose that it is the element itself which thus grows putrid and offensive, but the substances with which it is impregnated. It is true, the utmost pre- cautions are taken to destroy all vegetable and animal substances that may have previ- ously been lodged in it, by boiling ; but, not- withstanding this, there are some that will still survive the operation, and others that find their way during the time of its stowage. Sea- men, therefore, assure us, that their water is generally found to putrefy twice, at least, and sometimes three times, in a long voyage. In about a month after it has been at sea, when the bung is taken out of the cask, it sends up o noisonie and dangerous vapour, which THE EARTH. 51 woulct take fire upon the application of a can- dle." The whole body of the water then is found replete with little worm-like insects, that float, with great briskness, through all its parts. These generally live for about a cou- ple of days ; and then dying, by depositing their spoils, for awhile increase the putrefac- tion. After a time, the heavier parts of these sinking to the bottom, the lighter float in a scum, at the top ; and this is what mariners call, the water's purging itself. There is still, however, another race of insects, which are bred, very probably, from the spoils of the former ; and produce, after some time, similar appearances : these dying, the water is then thought to change no more. However, it ve- ry often happens, especially in hot climates, that nothing can drive these nauseous insects from the ship's store of water. They often increase to a very disagreeable and frightful size, so as to deter the mariner, though parch- ing with thirst, from tasting that cup which they have contaminated. This water, as thus described, therefore, is a very different fluid from that simple element- ary substance upon which philosophical the- ories have been founded ; and concerning the nature of which there have been so many dis- putes. Elementary water is no way com- pounded ; but is without taste, smell, or colour; and incapable of being discerned by any of the senses, except the touch. This is the famous dissolvent of the chymists, into which, as they have boasted, they can reduce all bodies; and which makes up all other substances, only by putting on a different dis- guise. In some forms, it is fluid, transparent, and evasive of the touch; in others, hard, firm, and elastic. In some, it is stiffened by cold ; in others, dissolved by fire. Accord- ing to them, it only assumes external shapes from accidental causes ; but the mountain is as much a body of water, as the cake of ice that melts on its brow ; and even the philoso- pher himself is composed of the same materi- als with the cloud or meteor which he con- templates. Speculation seldom rests when it begins. Others, disallowing the universality of this substance, will not allow that in a state ofna- " Phil. Trans, vol. v. part ii. p. 71.' ture there is any such thing as Avater at all. " What assumes the appearance," say they, " is nothing more than melted ice. Ice is the real element of Nature's making ; and when found in a state of fluidity, it is then in a state of violence. All substances are naturally hard; but some more readily melt with heat than others. It requires a great heat to melt iron; a smaller heat will melt copper; silver, gold, tin, and lead, melt with smaller still ; ice. which is a body like the rest, melts with a very moderate warmth; and quicksilver melts with the smallest warmth of all. Water, there- fore, is but ice kept in continual fusion ; and still returning to its former state, when the heat is taken away." Between these oppo- site opinions, the controversy has been car- ried on with great ardour, and much has been written on both sides ; and yet, when we conn- to examine the debate, it will probably ter- minate in this question, whether cold or heat first began their operations upon water ? This is a fact of very little importance, if known : and, what is more, it is a fact we can never know. Indeed, if we examine into the operation? of cold and heat upon water, we shall find that they produce somewhat similar effects. Water dilates in its bulk, by heat, to a very considerable degree ; and, what is more ex- traordinary, it is likewise dilated by cold in the same manner. If water be placed over a fire, it grows gra- dually larger in bulk, as it becomes hot, until it begins to boil ; after which no art can either increase its bulk or its heat. By increasing the fire, indeed, it may be more quickly eva- porated away ; but its heat and its bulk still continue the same. By the expanding of this fluid, by heat, philosophers have found a way to determine the warmth or the coldness of other bodies ; for if put into a glass tube, by its swelling and rising, it shows the quantity of heat in the body to which it is applied ; and by its contracting and sinking, it shows the absence of the same. Instead of using water in this instrument, which is called a thermo- meter, they now make use of spirit of wine, which is not apt to freeze, and which is en- dued even with a greater expansion, by heat, than water. The instrument consists of no- thing more than a hollow ball of glass, with a P 52 A HISTORY OF long tube growing out of it. This being part- ly filled with spirits of wine tinctured red, so as to be seen when it rises, the ball is plunged into boiling water, which making the spirit within expand and rise in the tube, the water marks the greatest height to which it ascends; at this point the tube is to be broken off, and then herrnetrically sealed, by melting the glass with a blow-pipe; a scale being placed by the side, completes the thermometer. Now as the fluid expands or condenses with heat or cold, it will rise and fall in the tube in pro- portion; and the degree or quantity of ascent or descent will be seen in the scale. No lire, as was said, can make water hotter, after it begins to boil. We can, therefore, at any time be sure of an equable certain heat ; which is that of boiling water, which is in- variably the same. The certainty of such a heat is not less useful than the instrument that measures it. It affords a standard, fixed de- gree of heat over the whole world ; boiling water being as hot in Greenland as upon the coast of Guinea. One fire is more intense than another; of heat there are various de- grees; but boiling water is a heat every where the same, and easily procurable. As heat thus expands water, so cold, when it is violent enough to freeze the same, pro- duces exactly the same effect, and expands it likewise. Thus water is acted upon in the same manner by two opposite qualities; being dilated by both. As a proof that it is dilated by cold, we have only to observe the ice floating on the surface of a pond, which it would not do were it not dilated, and grown more bulky, by freezing, than the water which remains unfroze. Mr. Boyle, however, put the matter past a doubt, by a variety of ex- periments." Having poured a proper quan- tity of water into a strong earthen vessel, he exposed it, uncovered, to the open air, in frosty nights ; and observed, that continually the ice reached higher than the water before it was frozen. He filled also a tube with water, and stopped both ends with wax: the water, when frozen, was found to push out the stopples from both ends ; and a rod of ice ap- peared at each end of the tube, which showed how much it was swollen by the cold within. Boyle, voL i. p. 610. From hence, therefore, we may be very certain of the cold dilating of the water; and experience also shows that the force of this expansion has been found as great as any which heat has been found to produce. The touch-hole of a strong gun-barrel being stop- ped, and a plug of iron forcibly driven into the muzzle, after the barrel had been filled with water, it was placed in a mixture of ice and salt; the plug, though soldered to the barrel, at first gave way, but being fixed in more firmly, within a quarter of an hour the gun-barrel burst with a loud noise, and blew up the cover of the box wherein it lay. Such is its force in an ordinary experiment. But it has been known to burst cannons, filled with water, and then left to freeze ; for the cold congealing the water, and the ice swell- ing, it became irresistible. The bursting of rocks by frost, which is frequent in the north- ern climates, and is sometimes seen in our own, is an equal proof of the expansion of congealed water. For having by some means insinuated itself into the body of the rock, it has remained there till the cold w as sufficient to affect it by congelation. But when once frozen, no obstacle is able to confine it from dilating ; and, if it cannot otherwise find room, the rock must burst asunder. This alteration in the bulk of water might have served as a proof that it was capable of being compressed into a narrower space than it occupied before ; but, till of late, water was held to be incompressible. The general opi- nion was, that no art whatsoever could squeeze it into a narrower compass ; that no power on earth, for instance, could force a pint of water into a vessel that held an hair's- breadth less than a pint And this, said they, appears from the famous Florentine experi- ment ; where the water, rather than suffer a compressure, was seen to ooze through the pores of the solid metal ; and, at length, mak- ing a cleft in the side, spun out with great vehemence. But later trials have proved that water is very compressible, and partakes of that elasticity which every other body pos- sesses in some degree. Indeed, had not man- kind been dazzled by the brilliancy of one in- conclusive experiment, there were numerous reasons to convince them of its having the same properties with other substances. Ice, THE EARTH. which is water in another state, is very elastic. A stone, flung slantingly along the surface of a pond, bounds from the water several times; which shows it to be elastic also. But the trials of Mr. Canton have put this past all doubt ; which being somewhat similar to those of the great Boyle, who pressed it with weights properly applied, carry sufficient conviction. What has been hitherto related, is chiefly applicable to the element of water alone ; but its fluidity is a property that it possesses in common with several other substances, in other respects greatly differing from it. That quality which gives rise to the definition of the fluid, namely, that its parts are in a con- tinual intestine motion, seems extremely ap- plicable to water. What the shapes of those parts are, it would be vain to attempt to dis- cover. Every trial only shows the futility of the attempt; all we find is, that they are ex- tremely minute ; and that they roll over each other with the greatest ease. Some, indeed, from this property alone, have not hesitated to pronounce them globular; and we have, in all our hydrostatical books, pictures of these little globes in a state of sliding and rolling over each other. But all this is merely the work of imagination; we know that sub- stances of any kind, reduced very small, as- sume a fluid appearance, somewhat resem- bling that of water. Mr. Boyle, after finely powdering and sifting a little dry powder of plaister of Paris, put it in a vessel over the fire, where it soon began to boil like water, exhibiting all the motions and appearances of a boiling liquor. Although but a powder, the parts of which we know are very different from each other, and just as accident has formed them, yet it heaved in great waves like water. Upon agitation, a heavy body will sink to the bottom, and a light one emerge to the top. There is no reason, then, to suppose the figure of the parts of water round, since we see their fluidity very well imitated by a composition, the parts of which are of various forms and sizes. The shape of the parts of water, therefore, we must be content to con- tinue ignorant of. All we know is, that earth, air, and fire, conduce to separate the parts from each other. Earthy substances divide the parts from each other, and keep them asunder. This division may be so great, that the water will entirely lose its fluidity thereby. Mud, pot- ter's clay, and dried bricks, are but so many different combinations of earth and water: each substance in which the parts of water are most separated from each other, appear- ing to be the most dry. In some substances, indeed, where the parts of water are greatly divided, as in porcelain, for instance, it is no easy matter to recover and bring them to- gether again; but they continue in a manner fixed and united to the manufactured clay. This circumstance led Doctor Cheney into a very peculiar train of thinking. He sus- pected that the quantity of water, on the surface of the earth, was daily decreasing. For, says he, some parts of it are continually joined to vegetable, animal, and mineral sub- stances, which no art can again recover. United with these, the water loses its fluidity; for if, continues he, we separate a few parti- cles of any fluid, and fasten them to a solid body, 6r keep them asunder, they will be fluid no longer. To produce fluidity, a con- siderable number of such particles are re- quired ; but here they are close, and destitute of their natural properties. Thus, according to him, the world is growing every day harder and harder, and the earth firmer and firmer; and there may come a time when every ob- ject around us may be stiffened in universal frigidity ! However, we have causes enough of anxiety in this world already, not to add this preposterous concern to the number. That air also contributes to divide the parts of water, we can have no manner of doubt ; some have even disputed whether water be not capable of being turned into air. How- ever, though this cannot be allowed, it must be granted, that it may be turned into a sub- stance which greatly resembles air (as we have seen in the experiment of the aeolipile) with all its properties ; except that, by cold, this new-made air may be condensed again into water. But of all the substances which tend to divide the parts of water, fire is the most powerful. Water, when heated into steam, acquires such force, and the parts of it tend to fly off from each other with such violence, that no earthly substance we know of is strong to confine them. A single drop of enough A HISTORY OF water, converted into steam, has been found capable of raising a weight of twenty tons ; and would have raised twenty thousand, were the vessel confining it sufficiently strong, and the fire below increased in proportion. From this easy yielding of its parts to ex- ternal pressure, arises the art of determining the specific gravity of bodies by plunging them in water ; with many other useful dis- coveries in that part of natural philosophy, called hydrostatics. The laws of this science, which Archimedes began, and Pascal, Avith some other of the moderns, have much im- proved, rather belongs to experimental than to natural history. However, I will take leave to mention some of the most striking paradox- es in this branch of science, which are as well confirmed by experiment, as rendered uni- versal by theory. It would, indeed, be un- pardonable, while discoursing on the proper- ties of water, to omitgiving some account of the manner in which it sustains such immense bulks as we see floating upon its soft and yielding surface : how some bodies, that are known to sink at one time, swim with ease, if their surface be enlarged: how the heaviest body, even gold itself, may be made to swim upon water; and how the lightest, such as cork, shall remain sunk at the bottom : how the pouring in of a single quart of water, will burst a hogshead hooped with iron : and how it ascends, in pipes, from the valley, to travel over the mountain : these are circumstances that are at first surprising ; but, upon a slight consideration, lose their wonder. " In order to conceive the manner in which all these wonders are effected, we must be- gin by observing that water is possessed of an invariable property, which has not hither- to been mentioned ; that of always keeping its surface level and even. Winds, indeed, may raise it into waves, or art spurt it up in foun- tains ; but ever, when left to itself, it sinks in- to a smooth even surface, of which no one part is higher than another. If I should pour vrater, for instance, into the arm of a pipe of the shape of the letter U, the fluid would rise in the other arm just to the same height; be- In the above sketch, the manner of demonstrating used by Monsieur D'Alembert is made use of, as the most obvious, and the most satisfactory. Vide Essai sur, &c. cause, otherwise, it would not find its level, which it invariably maintains. A pipe bend- ing from one hill down into the valley, and rising by another, may be considered as a tube of this kind, in which the water, sinking in one arm, rises" to maintain its level in the other. Upon this principle all water-pipes depend; which can never raise the water higher than the fountain from which they proceed. Again, let us suppose for a moment, that the arms of the pipe already mentioned, may be made long or short at pleasure ; and let us still further suppose, that there is some ob- stacle at the bottom of it, which prevents the water poured into one arm, from rising in the other. Now it is evident, that this obstacle at the bottom will sustain a pressure from the water in one arm, equal to what would make it rise in the other; and this pressure will be great, in proportion as the arm filled with wa- ter is tall. We may, therefore, generally con- clude, that the bottom of every vessel is pres- sed by a force, in proportion to the height of the water in that vessel. For instance, if the vessel filled with water be forty feet high, the bottom of that vessel will sustain such a pres- sure as would raise the same water forty feet high, which is very great. From hence we see how extremely apt our pipes, that con- vey water to the city, are to burst ; for de- scending from a hill of more than forty feet high, they are pressed by the water contained in them, with a force equal to what would raise it to more than forty feet high ; and that this is sometimes able to burst a \vooden pipe, we can have no room to doubt of. Still recurring to our pipe, let us suppose one of its arms ten times as thick as the other; this will produce no effect whatsoever upon the obstacle below, w r hich we supposed hin- dering its rise in the other arm ; because, how thick soever the pipe may be, its contents would only rise to its own level; and it will, therefore, press the obstacle with a force equal thereto. We may, therefore, univer- sally conclude, that the bottom of any vessel is pressed by its water, not as it is broad or narrow, but in proportion as it is high. Thus the water contained in a vessel not thicker than my finger, presses its bottom as forcibly as the water contained in an hogshead of an THE EARTH. 55 equal height ; and, if we made holes in the bottoms of both, the water would burst out as forceful from the one as the other. Hence we may, with great ease, burst an hogshead with a single quart of water; and it has been often done. W e have only," for this, to place an hogshead on one end, filled with water : we then bore a hole in its top, into which we Elant a narrow tin pipe, of about thirty feet igh : by pouring a quart of water into this, at the top, as it continues to rise higher in the pipe, it will press more forcibly on the bottom and sides of the hogshead below, and at last burst it. Still returning to our simple instrument of demonstration. If we suppose the obstacle at the bottom of the pipe to be moveable, so as that the force of the water can push it up into the other arm ; such a body as quick- silver, for instance. Now, it is evident, that the weight of water weighing down upon this quicksilver in one arm, will at last press it up in the other arm ; and will continue to press it upwards, until the fluid in both arms be up- on a par. So that here we actually see quick- silver, the heaviest substance in the world, except gold and platina, floating upon a wa- ter, which is but a very light subsbince. When we see water thus capable of sus- taining quicksilver, we need not be surprised that it is capable of floating much lighter sub- stances, ships, animals, or timber. When any thing floats upon water, we always see that a part of it sinks in the same. A cork, a ship, a buoy,each buries itself in a bed on the sur- face of the water; this bed may be considered as so much water displaced; the water Will, therefore, lose so much of its own weight, as is equal to the weight of that bed of water which it displaces. If the body be heavier than a similar bulk of water, it will sink; if lighter, it '.vill swim. Universally, therefore, a body plunged in water, loses as much of its weight as is equal to the weight of a body of water of its own bulk. Some light bodies, therefore, such as cork, lose much of their weight, and therefore swim; other more pon- derous bodies sink, because they are heavier than their bulk of water. Upon this simple theorem entirely depends a IN 7 ollet:'s Lectures. NO. 6. the art of weighing metals hydrostatically. I have a guinea, for instance, and desire to know whether it be pure gold ; I have weigh- ed it in the usual way with another guinea, and find it exactly of the same weight, but still I have some suspicion, from its greater bulk, that it is not pure^ In order to deter- mine this, I have nothing more to do than to weigh it in water with that same guinea that I know to be good, and of the same weight : and this will instantly show the difference ; for the true ponderous metal will sink, and the false bulky one will be sustained in pro- portion to the greatness of its surface. Those whose business it is to examine the purity of metals, have a balance made for this purpose, by which they can precisely determine which is most ponderous, or, as it is expressed, which has the greatest specific gravity. Se- venty-one pound and a half of quicksilver, is found to be equal in bulk to a hundred pound weight of gold. In the same propor- tion sixty of lead, fifty-four of silver, forty- seven of copper, forty-five of brass, forty-two of iron, and thirty-nine of tin, are each equal to an hundred pound of the same mosi pon- derous of all metals. This method of precisely determining the parity of gold, by weighing in water, was first discovered by Archimedes, to whom mankind have been indebted for many useful discove- ries. Hiero, king of Sicily, having sent a cer- tain quantity of gold to be made into a crown, the workman, it seems, kept a part for his own use, and supplied the deficiency with a baser metal. His fraud was suspected by the king, but could not be detected; lill he applied to Archimedes, who weighed the crown in water; and, by this method, inform- ed the king of the quantity of gold which was taken away. \. It has been said, that all fluids endeavour to preserve their level ; and, likewise, that a body pressing on the surface, tended to de- stroy that level. From hence, therefore, it will ensily be inferred, that the deeper any body sinks, the greater will be the resistance of the depressed fluid beneath. It will be asked, therefore, as the resistance increases in proportion' as the body descends, how comes the body, after it has got a certain way, to sink at all ? The answer is obvious : Q A HISTORY OF From the fluid above pressing it down with almost as great a force as the fluid beneath presses it up. Take away, by any art, the pressure of the fluid from above, and let only the resistance of the fluid from below be suf- fered to act, and after the body is gone down very deep, the resistance will be insuperable. To give an instance : A small hole opens in the bottom of a ship at sea, forty feet we will suppose below the surface of the water; through this the water bursts up with great violence ; I attempt to stop it with my hand, but it pushes the hand violently away. Here the hand is, in fact, a body attempting to sink upon water, at a depth of forty feet, with the pressure from above taken away. The wa- ter, therefore, will overcome my strength; and Avill continue to burst in till it has got to its level : if I should then dive into the hold, and clap my hand upon the opening, as before, I should perceive no force acting against my hand at all ; for the water above presses the hand as much down against the hole, as the water without presses it upward. For this reason, also, when we dive to the bottom of the water, we sustain a very great pressure from above, it is true, but it is counteracted by the pressure from below ; and the whole acting uniformly on the surface of the body, wraps us close round without injury. As I have deviated thus far, I will just men- tion one or two properties more, which water, and all such like fluids, is found to possess. " This phenomenon, which has so long embarrassed philosophers, is easily soluble upon the principle, that the attraction between the particles of glass and water is greater than the attraction between the particles of water themselves : for, if a glass tube be held parallel to the horizon, and a drop of water be applied to the under side of the tube, it will adhere to it : nor will it fall from the And, first, their ascending in vessels which are emptied of air, as in our common pumps for instance. The air, however, being the agent in this case, we must previously ex- amine its properties, before we undertake the explanation. The other property to be mentioned is, that of their ascending in small capillary tubes. This is one of the most ex- traordinary and inscrutable appearances in nature. Glass tubes may be drawn, by means of a lamp, as fine as a hair ; still preserving their hollow within. If one of these be plant- ed in a vessel of water, or spirit of wine, the liquor will immediately be seen to ascend ; and it will rise higher, in proportion as the tube is smaller ; a foot, two feet, and more. How does this come to pass ? Is the air the cause? No: the liquor rises, although the air be taken away. Is attraction the cause ? No : for quicksilver does not ascend, which it otherwise would. Many have been the theories of experimental philosophers to ex- plain this property. Such as are fond of travelling in the regions of conjecture, may consult Hawksbee, Morgan, Jurin, or Watson, who have examined the subject with great minuteness. Hitherto, however, nothing but doubts, instead of knowledge, have been the result of their inquiries. It will not, there- fore, become us to enter into the minute- ness of the inquiry, when we have so many greater wonders to call our attention away. 8 glass, till its bulk and gravity are so far increased as to overbalance the attraction of the glass. Hence it is easy to conceive, how sensibly such a power must act on the surface of a fluid not viscid, as water, contained within the cavity of a small glass tube ; as also that the quantity of the fluid raised, will be as the surface of the bore which it fills, that is, as the diameter of the tube. THE EARTH. CHAPTER XIV. OF THE ORIGIN OF RIVERS. " THE sun ariseth, and the sun goeth down, and pants for the place from whence he arose. All things are filled with labour, and man cannot utter it. All rivers run into the sea, yet the sea is not full. Unto the place whence the rivers come, thither they return again. The eye is not satisfied with seeing, nor the ear with hearing.'" Thus speaks the wisest of the Jews. And at so early a period was the curiosity of man employed in observing these great circulations of nature. Every eye attempted to explain those appearances; and every philosopher who has long thought up- on the subject, seems to give a peculiar solu- tion. The inquiry whence rivers are produ- ced ; whence they derive those unceasing stores of water, which continually enrich the world with fertility and verdure ; has been variously considered, and divided the opin- ions of mankind more than any other topic in natural history. In this contest the various champions may be classed under two leaders ; Mr. De la Hire, who contends that rivers must be sup- plied from the sea, strained through the pores of the earth ; and Dr. Halley, who has endea- voured to demonstrate that the clouds alone are sufficient for the supply. Both sides have brought in mathematics to their aid ; and have shown that long and laborious cal- culations can at any time be made to obscure both sides of a question. De la Hire b begins his proofs, that rain- water, evaporated from the sea, is insufficient for the production of rivers; by showing that rain never penetrates the surface of the earth above sixteen inches. From thence he infers, that it is impossible for it, in many cases, to sink so as to be found at such considerable depths below. Rain-water, he grants, is often Been to mix with rivers, and to swell their currents ; but a much greater part of it eva- a Ecclesiastes, chap. i. ver. 5, J, 8. b Hist, de 1'Acad. 1713, p. 56. porates. " In fact," continues he, " if we sup- pose the earth every where covered with water, evaporation alone would be sufficient to carry off two feet nine inches of it in a year: and yet we very well know, that scarcely nineteen inches of rain-water falls in that time ; so that evaporation would car- ry off a much greater quantity than is ever known to descend. The small quantity of rain-water that falls is, therefore, but barely sufficient for the purposes of vegetation. Two leaves of a fig-tree have been found, by ex- periment, to imbibe from the earth, in five hours and a half, two ounces of water. This implies the great quantity of fluid that must be exhausted in the maintenance of one sin- gle plant. Add to this, that the waters of the river Rungis will, by calculation, rise to fifty inches; and the whole country from whence they are supplied!!, ever receives fif- ty inches in the year by rain. Besides this, there are many salt springs, which are known to proceed immediately from the sea, and are subject to its flux and reflux. In short, wherever we dig beneath the surface of the earth, except in a very few instances, water is to be found : and it is by this subterraneous water that springs and rivers, nay, a great part of vegetation itself, is supported. It is this subterraneous water which is raised into steam, by the internal heat of the earth, that feeds plants. It is this subterraneous water that distils through interstices; and there, cooling, forms fountains. It is this, that by the addition of rains, is increased into rivers, and pours plenty over the whole earth." On the other side of the question/ it is as- serted, that the vapours which are exhaled from the sea, and driven by the winds upon land, are more than sufficient to supply not only plants with moisture, but also to furnish a sufficiency of water to the greatest rivers. c Phil. Trans. voL ii. p. 128. A HISTORY OF For this purpose, an estimate has been made of the quantity of water emptied at the mouths of the greatest rivers; and of the quantity also raised from the sea by evapo- ration ; arid it has been found, that the latter by far exceeds the former. This calculation was made by Mr. Marriotte. By him it was found, upon receiving such rain as fell in a year, in a proper vessel fitted for that pur- pose, that, one year with another, there might fall about twenty inches of water upon the surface of the earth, throughout Europe. It was also computed that the river Seine, from its source to the city of Paris, might cover an extent of ground, that would supply it annually with above seven millions of cubic feet of this water, formed by evaporation. But upon computing the quantity which pass- ed through the arches of one of its bridges in a year, it was found to amount only to two hundred and eighty millions of cubic feet, which is not above the sixth part of the for- mer number. Hence it appears, that this ri- ver may receive a supply, brought to it by the evaporated waters of the sea, six times greater than what it gives back to the sea by its current ; and, therefore, evaporation is more than sufficient for maintaining the great- est rivers, and supplying the purposes also of vegetation. In this manner, the sea supplies sufficient humidity to the air, for furnishing the earth with all necessary moisture. One part of its vapours fall upon its own bosom, before they arrive upon land. Another part is arrested by the sides of mountains, and is compelled, by the rising stream of air, to mount upward towards the summits. Here it is presently precipitated, dripping down by the crannies of the stone. In some places, entering into the caverns of the mountain, it gathers in those receptacles, which being once filled, all the rest overflows; and breaking out by the sides of the hills, forms single springs. Many of these run down by the valleys or guts between the ridges of the mountain, and, coming to unite, form little rivulets or brooks ; many of these meeting in one common valley, and gaining the plain ground, being grown less rapid, become a river; and many of Phil. Trans. vol. ii. p. 128. these uniting, make such vast bodies of water, as the Rhine, the Rhone, and the Danube. There is still a third part, which falls upon the lower grounds, and furnishes plants with their wonted supply. But the circulation does not rest even here ; for it is again exha- led into vapour hy the action of the sun ; and afterwards returned to that great mass of wa- ters whence it first arose. "This," adds Dr. Halley, "seems the most reasonable hypo- thesis ; and much more likely to be true, than that of those who derive all springs from the filtering of the sea-waters, through certain imaginary tubes or passages within the earth ; since it is well known that the great- est rivers have their most copious fountains the most remote from the sea." a This seems the most general opinion ; and yet, after all, it is still pressed with great difficulties ; and there is still room to look out for a better theory. The perpetuity of many springs, which always yield the same quantity when the least rain or vapour is af- forded, as well as when the greatest, is a strong objection. Derham u mentions a spring at Upminster, which he could never perceive by his eye to be diminished, in the greatest droughts, even when all the ponds in the country, as well as an adjoining brook, have been dry for several months together. In the rainy seasons, also, it was never overflowed ; except sometimes, perhaps, for an hour or so, upon the immission of the external rains. He, therefore, justly enough concludes, that had this spring its origin from rain or vapour, there would be found an increase or decrease of its water, corresponding to the causes of its production. Thus the reader, after having been tossed from one hypothesis to another, must at last be content to settle in conscious ignorance. All that has been written upon this subject, af- fords him rather something to say, than some- thing to think ; something rather for others than for himself. Varenius, indeed, although he is at a loss for the origin of rivers, is by no means so as to their formation. He is pretty positive that all rivers are artificial. He boldly asserts, that their channels have been originally formed by the industry of man. b Derham Physico-Theol. THE EARTH. f>9 His reasons arc, that when a new spring breaks forth, the water does not make itself a new channel, but spreads over the adjacent land. " Thus," says he, " men are obliged to direct its course ; or, otherwise, Nature would never have found one." He enume- rates many rivers that are certainly known, from history, to have been dug by men. He alleges, that no salt-water rivers are found, because men did not want salt-water ; and as for salt, that was procurable at less expense than digging a river for it. How- ever, it costs a speculative man but a small expense of thinking to form such an hypothe- sis. It may, perhaps, engross the reader's patience to detain him longer upon it. Nevertheless, though Philosophy be thus ignorant, as to the production of rivers, yet the laws of their motion, and the nature of their currents, have been very well explain- ed. The Italians have particularly distin- guished themselves in this respect; and it is chiefly to them that we are indebted for the improvement." All rivers have their source either in moun- tains, or elevated lakes; and it is in their descent from these that they acquire that ve- locity which maintains their future current. At first their course is generally rapid and headlong ; but it is retarded in its journey, by the continual friction against its banks, by the many obstacles it meets to divert its stream, and by the plains generally becoming more level as it approaches towards the sea. If this acquired velocity be quite spent, and the plain through which the river passes is entirely level; it will, notwithstanding, still continue to run, from the perpendicular pressure of the water, which is always in ex- act proportion to the depth. This perpen- dicular pressure is nothing more than the weight of the upper waters pressing the low- er out of their places ; and, consequently, driving them forward, as they cannot recede against the stream. As this pressure is great- est in the deepest parts of the river, so we generally find the middle of the stream most rapid ; both because it has the greatest mo- tion thus communicated by the pressure, and S. Guglielmiui della Natui-a de Fiumi, passim. " Ibid. the fewest obstructions from the banks on either side. Rivers thus set into motion are almost al- ways found to make their own beds. Where they find the bed elevated, they wear its sub- stance away, and deposit the sediment in the next hollow, so as in time to make the bot- tom of their channels even. On the other hand, the water is continually gnawing and eating away the banks on each side ; and this with more force as the current happens to strike more directly against them. By these means it always has a tendency to ren- der them more straight and parallel to its own course. Thus it continues to rectify its banks, and enlarge its bed ; and, consequent- ly, to diminish the force of its stream, till there becomes an equilibrium between the force of the water, and the resistance of its banks, upon which both will remain without any further mutation. And it is happy for man that bounds are thus put to the erosion of the earth by water; and that we find all rivers only dig and widen themselves but to a certain degree. 1 " In those plains" and large valleys where great rivers flow, the bed of the river is usu- ally lower than any part of the valley. But it often happens, that the surface of the water is higher than many of the grounds that are adjacent to the banks of the stream. If, after inundations, we take a view of some rivers, we shall find their banks appear above wa- ter, at a time that all the adjacent valley is overflowed. This proceeds from the frequent deposition of mud, and such like substances, upon the banks, by the rivers frequently overflowing; and thus, by degrees, they be- come elevated above the plain ; and the wa- ter is often seen higher also. Rivers, as every one has seen, are always broadest at the mouth, and grow narrower towards their source. But what is less known, and probably more deserving curiosity, is, that they run in a more direct channel as they immediately leave their sources; and that their sinuosities and turnings become more numerous as they proceed. It is a certain sign among the savages of North America, c Buflbn, de Fleuves, passim, vol. ii. R CO A HISTORY OF that they are near the sea, when they find the rivers winding, and every now and then changing their direction. And this is even now become an indication to the Europeans themselves, in their journeys through those trackless forests. As those sinuosities, there- fore, increase as the river approaches the sea, it is not to be wondered at that they sometimes divide, and thus disembogue by different channels. The Danube disem- bogues into the Euxine by seven mouths ; the Nile by the same number ; and the Wolga by seventy. The currents" of rivers are to be estimated very differently from the manner in which those writers, who have given us mathemati- cal theories on this subject, represent them. They found their calculations upon the sur- face being a perfect plain from one bank to the other : but this is not the actual state of nature; for rivers, in general, rise in the middle ; and this convexity is greatest in proportion as the rapidity of the stream is greater. Any person, to be convinced of this, need only lay his eye, as nearly as he can, on a level with the stream, and looking across to the opposite bank, he will perceive the river in the midst to be elevated consi- derably above what it is at the edges. This rising, in some rivers, is often found to be three feet high; and is ever increased in pro- portion to the rapidity of the stream. In this case, the water in the midst of the current, loses a part of its weight, from the velocity of its motion; while that at the sides, for the contrary reason, sinks lower. It sometimes, however, happens, that this appearance is reversed ; for when tides are found to flow up with violence against the natural current of the water, the greatest rapidity is then found at the sides of the river, as the water there least resists the influx from the sea. On those occasions, therefore, the river pre- sents a concave rather than a convex surface ; and, as in the former case, the middle waters rose in a ridge, in this case they sink in a i arrow. The stream of all rivers is more rapid in proportion as its channel is diminished. For instance, it will be much swifter where it is a Button, de Fleuves, passim, vol. ii. ten yards broad, than where it is twenty , for the force behind still pushing the water forward, when it comes to the narrow part, it must make up by velocity what it wants in room. It often happens that the stream of a river is opposed by one of its jutting banks, by an island in the midst, the arches of a bridge, or some such obstacle. This produces not unfrequently a back current ; and the water having passed the arch with great velocity, pushes the water on each side of its direct current. This produces a side current, tend- ing to the bank ; and not unfrequently a whirlpool ; in which a large body of waters are circulated in a kind of cavity, sinking down in the middle. The central point of the whirlpool is always lowest, because it has the least motion ; the other parts are supported, in some measure, by the violence of theirs, and consequently rise higher as their motion is greater ; so that towards the extremity of the whirlpool, must be higher than towards the centre. If the stream of a river be stopped at the surface, and yet be free below ; for instance, if it be laid over by a bridge of boats, there will then be a double current ; the water at the surface will flow back, while that at the bottom will proceed with increased velocity. It often happens that the current at the bot- tom is swifter than at the top, when, upon violent land-floods, the weight of waters to- wards the source presses the waters at the bottom, before it has had time to communi- cate its motion to the surface. However, in all other cases, the surface of the stream is swifter than the bottom, as it is not retarded by rubbing over the bed of the river. It might be supposed that bridges, dams, and other obstacles in the current of a river, would retard its velocity. But the difference they make is very inconsiderable. The wa- ter, by these stoppages, gets an elevation above the object; which, when it has sur- mounted, it gives a velocity that recom- penses the former delay. Islands and turn- ings also retard the course of the stream but very inconsiderably ; any cause which di- minishes the quantity of the water, most sensibly diminishes the force and the velo- city of the stream. THE EARTH. An increase* of water in the bed of the river always increases its rapidity; except in cases of inundation. The instant the river has overflowed its banks, the velocity of its current is always turned that way, and the inundation is perceived to continue for some days ; which it would not otherwise do, if, as soon as the cause was discontinued, it ac- quired its former rapidity. A violent storm, that sets directly up against the course of the stream, will always retard, and sometimes entirely stop its course. I have seen an instance of this, when the bed of a large river was left entirely dry for some hours, and lish were caught among the stones at the bottom. Inundations are generally greater towards the source of rivers than farther down ; be- cause the current is generally swifter below j than above ; and that for the reasons already assigned. A little river b may be received into a large I one, without augmenting either its width or | depth. This, which at first view seems a paradox, is yet very easily accounted for. The little river, in this case, only goes towards increasing th-3 swiftness of the larger, and put- ting its dormant waters into motion. In this manner the Venetian branch of the Po was pushed on by the Ferrarese branch and that of Penaro, without any enlargement of its breadth or depth from these accessions. A river tending to enter another, either j perpendicularly, or in an opposite direction, j will be diverted by degrees from that direc- j tion ; arid be obliged to make itself a more ; favourable entrance downward, and more conspiring with the stream of the former. The union of two rivers into one, makes it flow the swifter ; since the same quantity of water, instead of rubbing against four shores, now only rubs against two. And, besides, i the current being deeper, becomes, of con- | sequence, more fitted for motion. With respect to the places from whence rivers proceed, it may be taken for a general rule, that the largest" and highest mountains ' supply the greatest and most extensive rivers. It may also be remarked, in whatever direc- tion the ridge of the mountain runs, the river Buffon, vol. ii. p. 62. b Guglielmini. takes an opposite course. If the mountain, for instance, stretches from north to south, the river runs from east to west; and so con- trariwise. These are some of the most ge- nerally received opinions with regard to the course of rivers ; however, they are liable to many exceptions; and nothing but an actual knowledge of each particular river can fur- nish us with an exact theory of its current. The largest rivers of Europe are, first, the Wolga, which is about six hundred and fifty leagues in length, extending from Rcschow to Astrachan. It is remarkable of this river, that it abounds with water during the sum- mer months of May and June ; but all the rest of the year is so shallow as scarce to cover its bottom, or allow a passage for loaded ves- sels that trade up its stream. It was up this river that the English attempted to trade into Persia, in which they were so unhappily dis- appointed, in the year 1741. The next in order is the Danube. The course of this is about four hundred and fifty leagues, from the mountains of Switzerland to the Black Sea. It is so deep between Buda and Belgrade, that the Turks and Christians have fleets of men of war upon it ; which frequently en- gaged during the last war between the Otto- mans and the Austrians : however, it is un- navigable further down, by reason of its cata- racts, which prevent its commerce into the Black Sea. The Don, or Tanais, which is four hundred leagues from the source of that branch of it called the Softna, to its mouth in the Euxine Sea. In one. part of its course, it approaches near the Wolga ; and Peter the Great had actually begun a canal, by which he intended joining those two rivers ; but this he did not live to finish. The Nieper, or Boristhenes, which rises in the middle of Mus- covy, and runs a course of three hundred and fifty leagues, to empty itself into the Black Sea. The Old Cossacks inhabit the banks and islands of this river; and frequently cross the Black Sea, to plunder the maritime places on the coasts of Turkey. The Dwina, which takes its rise in a province of the same name in Russia, that runs a course of three hundred leagues, and disembogues into the White Sea, a little below Archangel. c Doctor Halley. A HISTORY OF The largest rivers of Asia are, the Hohanho, in China, which is eight hundred and fifty leagues in length, computing from its source at Raja Ribron, to its mouth in the gulf of Changi. The Jenisca of Tartary, about eight hundred leagues in length, from the lake Se- linga, to the Icy Sea. This river is, by some, supposed to supply most of that great quan- tity of drift wood which is seen floating in the seas near the Arctic circle. The Oby, of five hundred leagues, running from the lake of Kila into the Northern Sea. The Amour, in Eastern Tartary, whose course is about five hundred and seventy-five leagues, from its source to its entrance into the sea of Kamtschatka. The Kiam, in China, five hun- dred and fifty leagues in length. The Ganges, one of the most noted rivers in the world, and about as long as the former. It rises in the mountains which separate India from Tartary ; and running through the dominions of the Great Mogul, discharges itself by se- veral mouths into the bay of Bengal. It is not only esteemed by the Indians for the depth and pureness of its stream, but for a supposed sanctity which they believe to be in its waters. It is visited annually by several hundred thousand pilgrims, who pay their devotions to the river as to a god : lor savage simplicity is always known to mistake the blessings of the Deity, for the Deity himself. They carry their dying friends from distant countries, to expire on its banks; and to be buried in its stream. The water is lowest in April or May ; but the rains beginning to fall soon after, the flat country is overflowed for several miles, till about the end of September; the waters then begin to retire, leaving a pro- lific sediment behind, that enriches the soil, and, in a few days time, gives a luxuriance to vegetation, beyond what can be conceived by an European. Next to this may be reckoned the still more celebrated river Euphrates. This rises from two sources, northward of the city Erzerum, in Turcomania, and unites about three days' journey below the same ; from whence, after performing a course of five hundred leagues, it falls into the gulf of Persia, fifty miles below the city of Bassora in Arabia. The river Indus is extended, from its source to its discharge into the Arabian Sea, four hundred leagues. The largest rivers of Africa are, the Senegal, which runs a course of not less than eleven hundred leagues, comprehending the Niger, which some have supposed to fall into it. However, later accounts seem to affirm that the Niger is lost in the sands, about three hundred miles up from the western coasts of Africa. Be this as it may, the Senegal is well known to be navigable for more than three hundred leagues up the country ; and how much higher it may reach is not yet dis- covered, as the dreadful fatality of the inland parts of Africa, not only deters curiosity, but even avarice, which is a much stronger pas- sion. At the end of last war, of fifty English- men that were sent to the factory at Galam, a place taken from the French, and nine hundred miles up the river, only one returned to tell the fate of his companions, who were destroyed by the climate. The celebrated river Nile is said to be nine hundred aud seventy leagues, from its source among the Mountains of the Moon, in Upper ^Ethiopia, to its opening into the Mediterranean Sea. The sources of this river were considered as inscrutable by the ancients; and the causes of its periodical inundation wero equally un- known. They have both been ascertained by the missionaries who have travelled into the interior parts of ^Ethiopia. The Nile takes its rise in the kingdom of Gojam," from a small aperture on the top of a mountain, which, though not above a foot and a half over, yet was unfathomable. This fountain, when arrived at the foot of the mountain, ex- pands into a river; and being joined by others, forms a lake thirty leagues long, and as many broad; from this, its channel, in some mea- sure, winds back to the country where it first began ; from thence, precipitating by fright- ful cataracts, it travels through a variety of desert regions, equally formidable, such as Amhara, Olaca, Damot, and Xaoa. Upon its arrival in the kingdom of Upper Egypt, it runs through a rocky channel, which some late travellers have mistaken for its cataracts. In the beginning of its course, it receives many lesser rivers into it; and Pliny was mistaken in saying that it received none. In the beginning also of its course, it has many Kircher, Mund.

Its an- nual overflowings arise from a very obvious cause, which is almost universal with the great rivers that take their source near the line. The rainy season, which- is periodical in those climates, floods the rivers ; and as this always happens in our summer, so the Nile is at that time overflown. From these inundations, the inhabitants of Egypt derive happiness and plenty; and, when the river does not arise to its accustomed heights, they prepare for an indifferent harvest. It begins to overflow about the seventeenth of June; it generally continues to augment for forty days, and decreases in about as many more. The time of increase and decrease, however, is much more inconsiderable now than it was among the ancients. Herodotus informs us, that it was a hundred days rising, and as many falling ; which shows that the inunda- tion was much greater at that time than at present. Mr. BufTon" has ascribed the pre- sent diminution, as well to the lessening of the Mountains of the Moon, by their substance having so long been washed down with the stream, as to the rising of the earth in Egypt, that has for so many ages received this ex- traneous supply. But we do not find, by the buildings that have remained since the times of the ancients, that the earth is much raised since then. Besides the Nile in Africa, we may reckon the Zara, and the Coanza, from the greatness of whose openings into the sea, and the rapidity of whose streams, we form an estimate of the great distance from whence they come. Their courses, however, are spent in watering deserts and savage coun- tries, whose poverty or fierceness have kept strangers away. But of all parts of the world, America, as its exhibits the most lofty mountains, so also it supplies the largest rivers. The foremost of these is the great river Amazon, which, from its source in the lake of Lauricocha, to its discharge into the Western Ocean, per- forms a course of more than twelve hundred leagues. 11 The breadth and depth of this river are answerable to its vast length ; and, where its width is most contracted, its depth Buffon, vol. ii. p. 82. is augmented in proportion. So great is the body of its waters, that other rivers, though before the objects of admiration, are lost in its bosom. It proceeds, after their junction, with its usual appearance, without any visible change in its breadth or rapidity ; and, if we may so express it, remains great without os- tentation. In some places it displays its whole magnificence, dividing into several large branches, and encompassing a multitude of islands ; and, at length, discharging itself into the ocean, by a channel of a hundred and fifty miles broad. Another river, that may almost rival the former, is the St. Lawrence, in Canada, which rising in the lake Assini- boils, passes from one lake to another, from Christinaux to Alempigo; from thence to lake Superior; thence to the lake Hurons; to lake Erie; to lake Ontario; and, at last, after a course of nine hundred leagues, pours their collected waters into the Atlantic Ocean. The river Mississippi is of more than seven hundred leagues in length, beginning at its source near the lake Assiniboils, and ending at its opening into the gulf of Mexico. The river Plate runs a length of more than eight hundred leagues from its source in the river Parana, to its mouth. The river Oroonoko is seven hundred and fifty leagues in length, from its source near Pasto, to its discharge into the Atlantic Ocean. Such is the amazing length of the greatest rivers ; and even in some of these, the most remote sources very probably yet continue unknown. In fact, if we consider the num- ber of rivers which they receive, and the little acquaintance we have with the regions through which they run, it is not to be wondered at that geographers are divided concerning the sources of most of them. As among a num- ber of roots by which nourishment is con- veyed to a stately tree, it is difficult to de- termine precisely that by which the tree is chiefly supplied ; so among the many branches of a great river, it is equally difficult to tell which is the original. Hence it may easily happen, that a similar branch is taken for the capital stream ; and its runnings are pursued, and delineated, in prejudice of some other branch that better deserved the name b Ulloa, vol. i. p. 388. (54 A HISTORY OF and the description. In this manner,* in Eu- rope, the Danube is known to receive thirty lesser rivers ; the Wolga, thirty-two or thirty- three. In Asia, the Hohanho receives thirty- five; the Jenisca above sixty; the Oby as many ; the Amour about forty ; the Nanquin receives thirty rivers,; the Ganges twenty; and the Euphrates about eleven. In Africa, the Senegal receives more than twenty rivers; the Nile receives not one for five hundred leagues upwards, and then only twelve or thirteen. In America, the river Amazon receives above sixty, and those very consi- derable ; the river St. Lawrence about forty, counting those which fall into its lakes ; the Mississippi receives forty; and the river Plate above fifty. I mentioned the inundations of the Ganges and the Nile ; but almost every other great river, whose source lies within the tropics, have their stated inundations also. The river Pegu has been called, by travellers, the In- dian Nile, because of the similar overflowings of its stream : this it does to an extent of thirty leagues on each side ; and so fertilizes the soil, that the inhabitants send great quan- tities of rice into other countries, and have still abundance for their own consumption. The river Senegal has likewise its inunda- tions, which cover the whole flat country of Negroland, beginning and ending much about the same time with those of the Nile ; as, in fact, both rivers rise from the same mountains. But the difference between the effects of the inundations in each river is remarkable : in the one, it distributes health and plenty; in the other, diseases, famine, and death. The inhabitants along the torrid coasts of the Senegal, can receive no benefit from any ad- ditional manure the river may carry down to their soil, which is by nature more than suf- ficiently luxuriant ; or, even if they could, they have not industry to turn it to any ad- vantage. The banks, therefore, of the rivers, tie uncultivated, overgrown with rank and noxious herbage, and infested with thousands of animals of various malignity. Every new flood only tends to increase the rankness of the soil, and to provide fresh shelter for the creatures that infest it. If the flood continues 8 Buffon. vol. ii. p. 74. but a few days longer than usual, the impro- vident inhabitants, who are driven up in the higher grounds, want provisions, and a famine ensues. When the river begins to return into its channel, the humidity and heat of the air are equally fatal ; and the carcases of in- finite numbers of animals, swept away by the inundation, putrefying in the sun, produce a stench that is almost insupportable. But even the luxuriance of the vegetation becomes a nuisance. I have been assured, by persons of veracity who have been up the river Sene- gal, that there are some plants growing along the coast, the smell of which is so powerful, that it is hardly to be endured. It is certain, that all the sailors and soldiers who have been at any of our factories there, ascribe the unwholesomeness of the voyage up the stream, to the vegetable vapour. However this be, the inundations of the rivers in this wretched part of the globe, contribute scarcely any advantage, if we except the beauty of the prospects which they afford. These, indeed, are finished beyond the utmost reach of art : a spacious glassy river, with its banks here and there fringed to the very surface by the mangrove-tree that grows down into the wa- ter, presents itself to view. Lofty forests of various colours, with openings between, car- peted with green plants, and the most gaudy flowers ; beasts and animals of various kinds, that stand upon the banks of the river, and, with a sort of wild curiosity, survey the mari- ners as they pass, contribute to heighten the scene. This is the sketch of an African pros- pect; which delights the eye, even while it destroys the constitution. Besides these annually periodical inunda- tions, there are many rivers that overflow at much shorter intervals. Thus most of those in Peru and Chili have scarcely any motion by night; but upon the appearance of the morning sun, they resume their former ra- pidity : this proceeds from the mountain snows, which, melting with the heat, increase the stream, and continue to drive on the cur- rent while the sun continues to dissolve them. Some rivers also flow with an even, steady current, from their source to the sea ; others flow with greater rapidity, their stream being poured down in a cataract, or swallowed by the sands, before they reach the sea. THE EARTH. 65 The rivers of those countries that have been least inhabited, are usually more rocky, uneven, and broken into waterfalls or cata- racts, than those where the industry of man has "been more prevalent. Wherever man comes, nature puts on a milder appearance : the terrible and the sublime are exchanged for the gentle and the useful ; the cataract is sloped away into a placid stream; and the banks become more smooth and even. a It mast have required ages to render the Rhone or the Loire navigable ; their beds must have been cleaned and directed ; their inequalities removed ; and, by a long course of industry, nature must have been taught to conspire with the desires of her controller. Every one's experience must have supplied instances of rivers thus being made to How more evenly, and more beneficially to mankind ; but there are some whose currents are so rapid, and falls so precipitate, that no art can obviate , and that must for ever remain as amazing in- stances of incorrigible nature. Of this kind are the cataracts of the Rhine; one of which I have seen exhibit a very strange appearance; it was that at Schaff- hausen, which was frozen quite across, and the water stood in columns where the cata- ract had formerly fallen. The Nile, as was said, has its cataracts. The river Vologda, in Russia, has two. The river Zara, in Africa, has one near its source. The river Velino, in Italy, has a cataract of above a hundred and fifty feet perpendicular. Near the city of Gottenburgh, 1 ' in Sweden, the river rushes down from a prodigious high precipice into a deep pit, with a terrible noise, and such dreadful force, that those trees designed for the masts of ships, which are floated down the river, are usually turned upside down in their fall, and often are shattered to pieces, by being dashed against the surface of the water in the pit ; this occurs if the masts fall sideways upon the water; but if they fall endways, they dive so far under water that they disappear for a quarter of an hour, or more : the pit into which they are thus plung- ed has been often sounded with a line of some hundred fathoms long, but no ground has been found hitherto. There is also a cata- * Bufibn vol. ii. p. 90. I ract at Powerscourt, in Ireland, in which, if I am rightly informed, the water falls three hundred feet perpendicular; which is a greater descent than that of any other cata- ract in any part of the world. There is a cataract at Albany, in the province of New York, which pours its stream fifty feet per- pendicular But of all the cataracts in the world, that of Niagara, in Canada, if we con- sider the great body of water that falls, must be allowed to be the greatest, and the most astonishing This amazing fall of water is made by the river St. Lawrence, in its passage from the lake Erie into the lake Ontario. We have already said that St. Lawrence was one of the largest rivers in the world ; and yet the whole of its waters are here poured down by a fall of a hundred and fifty feet perpendicu- lar. It is not easy to bring the imagination to correspond with the greatness of the scene; a river extremely deep and rapid, and that serves to drain the waters of almost all North America into the Atlantic ocean, is here poured precipitately down a ledge of rocks, that rise like a wall, across the whole bed of its stream. The width of the river, a little above, is near three quarters of a mile broad, and the rocks, where it grows narrower, are four hundred yards over. Their direction is not straight across, but hollowing inwards like a horse-shoe ; so that the cataract, which bends to the shape of the obstacle, rounding inwards, presents a kind of theatre the most tremendous in nature. Just in the middle of this circular wall of waters, a little island, that has braved the fury of the current, pre- sents one of its points, and divides the stream at top into two ; but it unites again long be- fore it has got to the bottom. The noise of the fall is heard at several leagues distance : and the fury of the waters at the bottom of their fall is inconceivable. The dashing pro- duces a mist that rises to the very clouds ; and that produces a most beautiful rainbow, when the sun shines. It may easily be con- ceived, that such a cataract quite destroys the navigation of the stream ; and yet some Indian canoes, as it is said, have been known to venture down it with safety. b Phil. Trans, vol. ii. p. 325. 66 A HISTORY OF Of those rivers that lose themselves in the sands, or are swallowed up by chasms in the earth, we have various information. What we are told by the ancients, of the river Al- pheus, in Arcadia, that sinks into the ground, and rises again near Syracuse, in Sicily, where it takes the name of Arethusa, is ra- ther more known than credited. But we have better information with respect to the river Tigris being lost in this manner under Mount Taurus ; of the Guadilquiver in Spain, being buried in the sands ; of the river Greatah, in Yorkshire, running underground, and rising again; and even of the great Rhine itself, a part of which is no doubt lost in the sands, a little above Leyden. But it ought to be observed of this river, that by much the greatest part arrives at the ocean : for, although the ancient channel which fell into the sea a little to the west of that city, be now entirely choked up, yet there are still a number of small canals, that carry a great body of waters to the sea : and besides, it has also two very large openings, the Lech, and the Waal, below Rotterdam, by which it empties itself abundantly. Be this as it will, nothing is more common in sultry and sandy deserts, than rivers being thus either lost in the sands, or entirely dried up by the sun. And hence we see, that un- der the Line, the small rivers are but few ; for such little streams as are common in Eu- rope, and which with us receive the name of rivers, would quickly evaporate, in those parching and extensive deserts. It is even confidently asserted, that the great river Niger is thus lost before it reaches the ocean; Krantz's History of Greenland, vol. i. p. 41. and that its supposed mouths, the Gambia, and the Senegal, are distinct rivers, that come a vast way from the interior parts of the country. It appears that the rivers un- der the Line are large ; but it is otherwise at the Poles, 8 where they must necessarily be small. In that desolate region, as the moun- tains are covered with perpetual ice, which melts but little, or not at all, the springs and rivulets are furnished with a very small sup- ply. Here, therefore, man and beast would perish, and die for thirst, if Providence had not ordered, that in the hardest winter, thaws should intervene, which deposit a small quan- tity of snow-water in pools under the ice ; and from this source the wretched inhabi- tants drain a scanty beverage. Thus, whatever quarter of the globe we turn to, we shall find new reasons to be satis- fied with that part of it in which we reside. Our rivers furnish all the plenty of the Afri- can stream, without its inundation; they have all the coolness of the Polar rivulet, with a more constant supply ; they may want the ter- rible magnificence of huge cataracts, or ex- tensive lakes, but they are more navigable, and more transparent ; though less deep and rapid than the rivers of the torrid zone, they are more manageable, and only wait the will of man to take their direction. The rivers of the torrid zone, like the monarchs of the country, rule with despotic tyranny, profuse in their bounties, and ungovernable in their rage. The rivers of Europe, like their kings, are the friends, and not the oppressors of the people ; bounded by known limits,and abridg- ed in the power of doing ill, directed by hu- man sagacity, and only at freedom to distri- bute happiness and plenty. THE EARTH. 67 CHAPTER XV. OF THE OCEAN IN GENERAL; AND OF ITS SALTNESS. IF we look upon a map of the world, we shall find that the ocean occupies considera- bly more of the globe, than the land is found to do. This immense body of waters is dif- fused round both the Old and New Conti- nent, to the south ; and may surround them also to the north, for what we know, but the ice in those regions has stopped our inqui- ries. Although the ocean, properly speak- ing, is but one extensive sheet of waters, con- tinued over every part of the globe, without interruption, and although no part of it is di- vided from the rest, yet geographers have distinguished it by different names ; as the Atlantic or Western Ocean, the Northern Ocean, the Southern Ocean, the Pacific Ocean, and the Indian Ocean. Others have divided it differently, and given other names ; as the Frozen Ocean, the Inferior Ocean, or the American Ocean. But all these being arbitrary distinctions, and not of Nature's making, the naturalist may consider them with indifference. In this vast receptacle, almost all the rivers of the earth ultimately terminate; nor do such great supplies seem to increase its stores ; for it is neither apparently swollen by their tribute, nor diminished by their fai- lure ; it still continues the same. Indeed, what is the quantity of water of all the rivers and lakes in the world, compared to that con- tained in this great receptacle ? B If we should offer to make a rude estimate, we shall find that all the rivers in the world, flowing into the bed of the sea, with a continuance of their present stores, would take up at least eight hundred years to till it to its present height. For, supposing the sea to be eighty- five millions of square miles in extent, and a quarter of a mile upon an average in depth, this, upon calculation, will give above twen- ty-one millions of cubic miles of water, as the contents of the whole ocean. Now, to esti- Buffon, vol. ii. p. ~Q. KO. 7- mate the quantity of water which all the ri- vers supply, take any one of them ; the Po, for instance, the quantity of whose discharge into the sea, is known to be one cubic mile of water in twenty-six days. Now it will be found, upon a rude computation, from the quantity of ground the Po, Avith its influent streams, covers, that all the the rivers of the world furnish about two thousand times that quantity of water. In the space of a year, therefore, they will have discharged into the sea about twenty-six thousand cubic miles of water ; and not till eight hundred years, will they have discharged as much water as is contained in the sea at present. I have no<. troubled the reader with the odd num- bers, lest he should imagine I was giving precision to a subject that is incapable of it. Thus great is the assemblage of waters dif- fused round our habitable globe ; and yet. immeasurable as they seem, they are mostly rendered subservient to the necessities and the conveniences of so little a being as man. Nevertheless, if it should be asked whe- ther they be made for him alone, the ques- tion is not easily resolved. Some philoso- phers have perceived so much analogy to man in the formation of the ocean, that they have not hesitated to assert its being made for him alone. The distribution of land and water, 1 " say they, is admirable ; the one being laid against the other so skilfully, that there is a just equipoise of the whole globe. Thus the Northern Ocean balances against the Southern ; and the New Continent is an ex- act counterweight to the Old, As to any ob jection from the ocean's occupying too large a share of the globe, they contend, that there could not have been a smaller surface em- ployed to supply the earth with a due share of evaporation. On the other hand, some take the gloomy side of the question; they b Derham's Physico-Theol. T 68 A HISTORY OF cither magnify 1 its apparent defects ; or as- sert, that b what seems defects to us, may be real beauties to some wiser order of beings. They observe, that multitudes of animals are concealed in the ocean, and but a small part of them are known ; the rest, therefore, they fail not to say, were certainly made for their own benefit, and not for ours. How far ei- ther of these opinions be just, I will not pre- sume to determine; but of this we are cer- tain, that God has endowed us with abilities to turn this great extent of waters to our own advantage. He has made these things, per- haps, for other uses ; but he has given us fa- culties to convert them to our own. This much agitated question, therefore, seems to terminate here. We shall never know whe- ther the things of this world have been made for our use; but we very well know that we have been made to enjoy them. Let us then boldly affirm, that the earth, and all its wonders, are ours; since we are fur- nished with powers to force them into our service. Man is the lord of all the sublunary creation ; the howling savage, the winding serpent, with all the untameable and rebel- lious offspring of nature, are destroyed in the contest, or driven to a distance from his ha- bitations. The extensive and tempestuous ocean, instead of limiting or dividing his power, only serves to assist his industry, and enlarge the sphere of his enjoyments. Its billows, and its monsters, instead of present- ing a scene of terror, only call up the cou- rage of this little intrepid being ; and the greatest danger that man now fears on the deep, is from his fellow-creatures. Indeed, when I consider the human race as Nature has formed them, there is but very little of the habitable globe that seems made for them. But when I consider them as accumu- lating the experience of ages, in commanding the earth, there is nothing so great, or so ter- rible. What a poor contemptible being is the naked savage, standing on the beach of the ocean, and trembling at its tumults ! How little capable is he of converting its terrors into benefits; or of saying, behold an ele- ment made wholly for my enjoyment ! He considers it as an angry deity, and pays it " Burner's Theory, passim. the homage of submission. But it is very different when he has exercised his mental powers ; when he has learnt to find his own superiority, and to make it subservient to his commands. It is then that his dignity begins to appear, and that the true Deity is justly- praised for having been mindful of man ; for having given him the earth for his habitation, and the sea for an inheritance. This power which man has obtained over the ocean, was at first enjoyed in common , and none pretended to a right in Liat ele- ment where all seemed intruders. The sea, therefore, was open to all till the time of the emperor Justinian. His successor Leo grant- ed such as were in possession of the shore the sole right of fishing before their respec- tive territories. The Thracian Bosphorus was the first that was thus appropriated ; and from that time it has been the struggle of most of the powers of Europe to obtain an exclusive right in this element. The repub- lic of Venice claims the Adriatic. The Danes are in possession of the Baltic. But the Eng- lish have a more extensive claim to the em- pire of all the seas encompassing the king- doms of England, Scotland, and Ireland ; and although these have been long contested, yet they are now considered as their indisputa- ble property. Every one knows that the great power of the nation is exerted on this element ; and that the instant England ceases to be superior upon the ocean, its safety be- gins to be precarious. It is in some measure owing to our de- pendance upon the sea, and to our commerce there, that we are so well acquainted with its extent and figure. The bays, gulfs, currents, and shallows of the ocean, are much better known and examined than the provinces and kingdoms of the earth itself. The hopes of acquiring wealth by commerce, has carried man to much greater length than the desire of gaining information could have done. In consequence of this, there is scarcely a strait or a harbour, scarcely a rock or a quicksand, scarcely an inflexion of the shore, or the jut- ting of a promontory, that has not been mi- nutely described. But as these present very little entertainment to the imagination, or de- b Pope's Ethic Epistle, passim. THE EARTH. light to any but those whose pursuits are lucrative, they need not be dwelt upon here. While the merchant and the mariner are soli- citous in describing currents and soundings, the naturalist is employed in observing won- ders, though not so beneficial, yet to him of a much more important nature. The saltness of the sea seems to be foremost. Whence the sea has derived that peculiar bitterish saltness which we find in it, appears, by Aristotle, to have exercised the curiosity of naturalists in all ages. He supposed (and mankind were for ages content with the solu- tion) that the sun continually raised dry sa- line exhalations from the earth, and deposit- ed them upon the sea ; and hence, say his followers, the waters of the sea are more salt at top than at bottom. But, unfortunately for this opinion, neither of the facts is true. Sea- salt is not to be raised by the vapours of the sun ; and sea-water is not salter at the top than at the bottom. Father Bohours is of opinion that the Creator gave the waters of the ocean their saltness at the beginning ; not only to prevent their corruption, but to enable them to bear greater burthens. But their saltness does not prevent their corrup- tion ; for stagnant sea-writer, like fresh, soon grows putrid: and, as for their bearing great- er burthens, fresh waters answer all the pur- poses of navigation quite as well. The esta- blished opinion, therefore, is that of Boyle," who supposes, " that the sea's saltness is sup- plied not only from rocks or masses of salt at the bottom of the sea, but also from the salt which the rains and rivers, and other waters, dissolve in their passage through many parts of the earth, and at length carry with them to the sea." But as there is a difference in the taste of rock-salt found at land, and that dissolved in the waters of the ocean, this may be produced by the plenty of nitrous and bitu- minous bodies that, with the salts, are like- wise washed into that great receptacle. These substances being thus once carried to the sea, must for ever remain there ; for they do not rise by evaporation, so as to be returned back from whence they came. Nothing but the fresh waters of the sea rise in vapours ; and all the saltness remains behind. Hence Boyle, vol. iii. p. 221. it follows, that every year the sea must be- come more and more salt ; and this specula- tion Doctor Halley carries so far as to lay down a method of finding out the age of the world by the saltness of its waters. " For if it be observed," 1 " says he, " what quantity of salt is at present contained in a certain weight of water, taken up from the Caspian Sea, for example, and, after some centuries, what great- er quantity of salt is contained in the sanif weight of water taken from the same place ; we may conclude, that in proportion as the saltness has increased in a certain time, so much must it have increased before that time ; and we may thus, by the rule of pro- portion, make an estimate of the whole time wherein the water would acquire the degree of saltness it should be then possessed of." All this may be fine ; however, an experi- ment, begun in this century, which is not to be completed till some centuries hence, is rather a little mortifying to modern curiosity : and, I am induced to think, the inhabitants round the Caspian Sea will not be apt to un- dertake the inquiry. t This saltness is found to prevail in every part of the ocean ; and as much at the sur- lace as at the bottom. It is also found in all those seas that communicate with the ocean; but rather in a less degree. The great lakes, likewise, that have no outlets nor communication with the ocean, are found to be salt: but some of them in less proportion. On the contrary, all those lakes through which rivers run into the sea, however extensive they be, are, notwithstand- ing very fresh: for the rivers do not deposite their salts in the bed of the lake, but carry them, with their currents, intotheocean. Thus the lakes Ontario and Erie,in North America, although for magnitude they may be consi- dered as inland seas, are, nevertheless, fresh- water lakes ; and kept so by the river St. Lawrence, which passes through them. But those lakes that have no communication with the sea, nor any rivers going out, although they be less than the former, are, however, always salt. Thus, that which goes by the name of the Dead Sea, though very small, when compared to those already mentioned, b Phil. Trans, vol. v. p. 218, 70 A HISTORY OF is so exceedingly salt, that its waters seem scarcely capable of dissolving any more. The lakes of Mexico, and of Titicaca, in Peru, though of no great extent, are, ne- vertheless, salt; and botli for the same reason. Those who are willing to turn all things to the best, have not failed to consider this salt- ness of the sea as a peculiar blessing from Providence, in order to keep so great an ele- ment sweet and wholesome. What founda- tion there may be in the remark, I will not pretend to determine ; but we shall shortly find a much better cause for its being kept sweet, namely, its motion. On the other hand, there have been many who have considered the subject in a differ- ent light, and have tried every endeavour to make salt-water fresh, so as to supply the wants of mariners in long voyages, or when exhausted of their ordinary stores. At first it was supposed simple distillation would do; but it was soon found that the bitter part of the water still kept mixed. It was then tried by uniting salt of tartar with sea-water, and distilling both; but here the expense was greater than the advantage. Calcined bones were next thought of; but a hogshead of cal- cined bones, carried to sea, would take up as much room as a hogshead of water, and was more hard to be obtained. In this state, therefore, have the attempts to sweeten sea- water rested ; the chymist satisfied with the reality of his invention ; and the mariner con- vinced of its being useless. I cannot, there- fore, avoid mentioning a kind of succeda- neum which has been lately conceived to an- swer the purposes of fresh water, when ma- riners are quite exhausted. It is well known, the persons who go into a warm bath, come out several ounces heavier than they went in; their bodies having imbibed a corres- pondent quantity of water. This more par- ticularly happens, if they have been previous- ly debarred from drinking, or go in with a violent thirst; which they quickly find quenched, and their spirits restored. It was supposed, that in case of a total failure of fresh-water at sea, a warm bath might be made of sea-water, for the use of mariners ; and that their pores would thus imbibe the fluid, without any of its salts, which would be I seen to crystallize on the surface of their bo- I dies. In this manner, it is supposed, a suffi- cient quantity of moisture may be procured to sustain life, till time or accident furnish a more copious supply. But, however this be, the saltness of the sea can by no means be considered as a prin- cipal cause in preserving its waters from pu- trefaction. The ocean has its currents, like rivers, which circulate its contents round the globe ; and these may be said to be the great agents that keep it sweet and wholesome. Its saltness alone would, by no means, answer this purpose : and some have even imagined that the various substances with which it is mixed, rather tend to promote putrescence than impede it. Sir Robert Hawkins, one of our most enlightened navigators, gives the following account of a calm, in which the sea continuing for some time without motion, be- gan to assume a very formidable appearance. " Were it not," says he, " for the moving of the sea, by the force of winds, tides, and cur- rents, it would corrupt all the world. The experiment of this I saw in the year 1590, lying with a fleet about the islands of Azores, almost six months; the greatest part of which time we were becalmed. Upon which all the sea became so replenished with several sorts of jellies, and forms of serpents, adders, and snakes, as seemed wonderful : some green, some black, some yellow, some white, some of divers colours, and many of them had life ; and some there were a yard and a half, and two yards long ; which had I not seen, I could hardly have believed. And hereof are wit- nesses all the company of the ships which were then present : so that hardly a man could draw a bucket of water clear of some corruption. In which voyage, towards the end thereof, many of every ship fell sick, and began to die apace. But the speedy passage into our country was a remedy to the crazed, and a preservative for those that were not touched." This shows, abundantly, how little the sea's saltness was capable of preserving it from putrefaction : but, to put the matter beyond all doubt, Mr. Boyle kept a quantity of sea- water, taken up in the English Channel, for some time barrelled up ; and, in the space of a few weeks, it began to acquire a fetid THE EARTH. smell :' he was also assured, by one of his ac- quaintance, who was becalmed for twelve or fourteen days in the Indian sea, that the water, for want of motion, began to stink; and that had it continued much longer, the stench would probably have poisoned him. It is the motion, therefore, and not the salt- ness of the sea, that preserves it in its present state of salubrity; and this, very probably, by dashing and breaking in pieces the rudi- ments, if I may so call them, of the various animals that would otherwise breed there, and putrefy. There are some advantages, however, which are derii ed from the saltness of the sea. Its waters be t ng evaporated, furnish that salt which is use ; *or domestic purposes; and, although In some places it is made from springs, and, ii otners, dug out of mines, yet the greatest quantity is made only from the sea. That which is called bay-salt, (from its coming to us by the Bay of Biscay,) is a stronger kind, made by evaporation in the sun : that called common salt, is evaporated in pans over the fire, and is of a much inferior quality to the former. Another benefit arising from the quantity of salt dissolved in the sea, is, that it thus becomes heavier, and, consequently, more buoyant. Mr. Boyle, who examined the dif- ference between sea-water and fresh, found that the former appeared to be about a forty- fifth part heavier than the latter. Those, also, who have had opportunities of bathing in the sea, pretend to have experienced a much greater ease in swimming there, than in fresh-water. However, as we see they have only a forty-fifth part more of their weight s-ustained by it, I am apt to doubt whether so minute a difference can be prac- tically perceivable. Be this as it may, as sea-water alters in its weight from fresh, so it is found also to differ from itself in different parts of the ocean. In general, it is per- ceived to be heavier, and consequently salter, the nearer we approach the Line. b But there is an advantage arising from the saltness of the waters of the sea, much greater than what has been yet mentioned ; which is, a Boyle, vol. iii. p. 222. Phil. Trans, vol. ii. p. 297- Macrobius. that their congelation is thus retarded. Some, indeed, have gone so far as to say, that c sea- water never freezes : but this is an assertion contradicted by experience. However, it is certain that it requires a much greater degree of cold to freeze it than fresh-water ; so that, while rivers and springs are seen converted into one solid body of ice, the sea is always fit for navigation, and no way affected by the coldness of the severest winter. It is, there- fore, one of the greatest blessings we derive from this element, that when at land all the stores of Nature arc locked up from us, we find the sea ever open to our necessities, and patient of the hand of industry. But it must not be supposed, because in our temperate climate we never see the sea frozen, that it is in the same manner open in every part of it. A very little acquaintance with the accounts of mariners, must have in- formed us, that at the polar regions it is em- barrassed with mountains, and moving sheets of ice, that often render it impassable. These tremendous floats are of different magnitudes; sometimes rising more than a thousand fee- above the surface of the water;' 1 sometimes diffused into plains of above two hundred leagues in length ; and, in many parts, sixty or eighty broad. They are usually divided by fissures ; one piece following another so close, that a person may step from one to the other. Sometimes mountains are seen rising amidst these plains, and presenting the ap- pearance of a variegated landscape, with hills and valleys, houses, churches, and towers. These are appearances in which all natu- ralists are agreed ; but the great contest is respecting their formation. Mr. Buffon as- serts," that they are formed from fresh-water alone ; which congealing at the mouths of great rivers, accumulate those huge masses that disturb navigation. However, this great naturalist seems not to have been aware that there are two sorts of ice floating in these seas; the flat ice, and the mountain ice : the one formed of sea-water only, the other of fresh/ The flat, or driving ice, is entirely com- posed of sea-water; which, upon dissolution, d Krantz's History of Greenland, vol. i. p. 31. ' Buffon, vol. ii. p. 91. * Krantz. 72 A HISTORY OF is found to be salt; and is readilydistinguished from the mountain or fresh-water ice, by its whiteness, and want of transparency. This ice is much more terrible to mariners than that which rises up in lumps : a ship can avoid the one, as it is seen at a distance ; but it often gets in among the other, which some- times closing, crushes it to pieces. This, which manifestly has a different origin from the fresh-water ice, may perhaps have been produced in the Icy Sea, beneath the Pole ; or along the coasts of Spitzberg, or Nova Zembla. The mountain-ice, as was said, is different in every respect, being formed of fresh-water, and appearing hard and transparent; it is generally of a pale green colour, though some pieces are of a beautiful sky blue; many large masses, also, appear gray; and some black. If e::r.mined more nearly, they are found to be incorporated with earth, stones, and brush- wood, w r ashed from the shore. On these also are sometimes found, not only earth, but nests with birds' eggs, at several hundred miles from land. The generality of these, though almost totally fresh, have, neverthe- less, a thick crust of salt-water frozen upon them, probably from the power that ice has sometimes to produce ice. Such mountains as are here described, are most usually seen at spring-time, and after a violent storm, driving out to sea, where they at first terrify the mariner, and are soon after dashed to pieces by the continual washing of the waves; or driven into the warmer regions of the south, there to be melted away. They some- times, however, strike back upon their native shores, where they seem to take root at the feet of mountains ; and, as Martius tells- us, are sometimes higher than the mountains themselves. Those seen by him were blue, full of clefts and cavities made by the rain, and crowned with snow, which alternately thawing and freezing every year, augmented their size. These, composed of materials more solid than that driving at sea, presented a variety of agreeable figures to the eye, that, with a little help from fancy, assumed the appearance of trees in blossom ; the inside of churches, with arches, pillars, and win- dows; and the blue coloured rays,darting from within, presented the resemblance of a glory. If we inquire into the origin and formation of these, which, as we see, are very different from the former, I think we have a very satis- factory account of them in Krantz's History of Greenland; and I will take leave to give the passage, with a very few alterations. " These mountains of ice," says he, " are not salt, like the sea-water, but sweet; and, therefore, can be formed no where except on the mountains, in rivers, in caverns, and against the hills near the sea-shore. The mountains of Greenland are so high, that the snow which falls upon them, particularly on the north side, is, in one night's time, wholly- converted into ice : they also contain clefts and cavities, where the sun seldom or never injects his rays : besides these, are projec- tions, or landing places, on the declivities of the steepest hills, where the rain and snow- water lodge, and quickly congeal. When now the accumulated Hakes of snow slide down, or fall with the rain from the eminences above on these prominences; or, when here and there a mountain-spring comes rolling down to such a lodging place, where the ice has already seated itself, they all freeze, and add their tribute to it. This, by degrees, waxes to a body of ice, that can no more be overpowered by the sun ; and which, though it may indeed, at certain seasons, diminish by a thaw, yet, upon the whole, through an- nual acquisitions, it assumes an annual growth. Such a body of ice is often promi- nent far over the rocks. It does not melt on the upper surface, but underneath ; and often cracks into many larger or smaller clefts, from whence the thawed water trickles out. By this it becomes, at last, so weak, that be- ing overloaded with its own ponderous bulk it breaks loose and tumbles down the rocks with a terrible crash. Where it happens to overhang a precipice on the shore, it plung- es into the deep with a shock like thunder : and with such an agitation of the water, as will overset a boat at some distance, as many a poor Greenlander has fatally experienced." Thus are these amazingice mountains launch- ed forth to sea, and found floating in the wa- ters round both the Poles. It is these that have hindered mariners from discovering the ex- tensive countries that lie round the South Pole : and that probably block up the pas sage to China bv the North. THE EARTH. 73 I will conclude this chapter with one effect more, produced by the saltness of the sea ; which is, the luminous appearance of its waves in the night. All who have been spec- tators of a sea by night, a little ruffled with winds, seldom fail of observing its fiery brightness. In "some places it shines as far as the eye can reach ; at other times, only "when the waves boom against the side of the vessel, or the oar dashes into the water. Some seas shine often ; others more seldom ; some, ever when particular winds blow ; and others, within a narrow compass ; a long tract of light being seen along the surface, whilst all the rest is hid in total darkness. It is not easy to account for these extraordi- nary appearances : some have supposed that a number of luminous insects produced the effect, and this is in reality sometimes the case ; in general, however, they have every resemblance to that light produced by elec- tricity ; and, probably, arise from the agita- tion and dashing of the saline particles of the fluid against each other. But the manner in which this is done, (for we can produce no- thing similar by any experiments hitherto made,) remains for some happier accident to discover. Our progress in the knowledge of Nature is slow ; and it is a mortifying consideration, that we are hitherto more indebted for success to chance than d us try. in- CHAPTER XVI. OF THE TIDES, MOTION, AND CURRENTS OF THE SEA; WITH THEIR EFFECTS. IT was said, in the former chapter, that the i waters of the sea were kept sweet by their motion, without which they would soon pu- trefy, and spread universal infection. If we look for final causes, here, indeed, we have a great and an obvious one that presents itself before us. Had the sea been made without motion, and resembling a pool of stagnant water, the nobler races of animated nature would shortly be at an end. Nothing would then be left alive but swarms of ill-formed creatures, with scarcely more than vegetable life ; and subsisting by putrefaction. Were this extensive bed of waters entirely quies- cent, millions of the smaller reptile kinds would there find a proper retreat to breed and multiply in ; they would find there no agitation, no concussion in the parts of the fluid to crush their feeble frames, or to force them from the places where they were bred ; there they would multiply in security and ease, enjoy a short life, and putrefying, thus again give nourishment to numberless other, as little worthy of existence as themselves. Boyle, vol. i. p. 294. But the motion of this great element effectu- ally destroys the number of these viler crea- tures ; its currents and its tides produce con- tinual agitations, the shock of which they are not able to endure; the parts of the fluid rub against each other, destroy all viscidi- ties ; and the ocean, if I may so express it, acquires health by exercise. The most obvious motion of the sea, and the most generally acknowledged, is that of its tides. This element is observed to flow for certain hours, from south towards the north ; in which motion or flux, which lasts about six hours, the sea gradually swells; so that entering the mouths of rivers, it drives back the river waters to their heads. After a continual flux of six hours, the sea seems to rest for a quarter of an hour; and then begins to ebb, or retire back again, from north to south, for six hours more ; in which time the waters sinking, the rivers resume their natural course. After a seeming pause of a quarter of an hour, the sea again begins to flow as before : and thus it has alternate- ly risen and fallen, twice a day, since the creation. 74 A HISTORY OF This amazing appearance did not fail to excite the curiosity, as it did the wonder of the ancients. After some wild conjectures of the earliest philosophers, it became well known, in the time of Pliny, that the tides were entirely under the influence, in a small degree, of the sun ; but in a much greater, of the moon. It was found that there was a flux and reflux of the sea, in the space of twelve hours fifty minutes, which is exactly the time of a lunar day. It was observed, that whenever the moon was in the meridian, or, in other words, as nearly as possible over any part of the sea, that the sea flowed to that part, and made a tide there ; on the con- trary, it was found, that when the moon left the meridian, the sea began to flow back again from whence it came ; and there might be said to ebb. Thus far the waters of the sea seemed very regularly to attend the mo- tions of the moon. But it appeared, likewise, that when the moon was in the opposite me- ridian, as far off on the other side of the globe, that there was a tide on this side also ; so that the moon produced two tides, one by her greatest approach to us ; and another by her greatest distance from us : in other words, the moon, in once going round the earth, produced two tides, always at the same time ; one on the part of the globe directly under her ; and the other, on the part of the globe directly opposite. Mankind continued for several ages con- tent with knowing the general cause of these wonders, hopeless of discovering the parti- cular manner of the moon's operation. Kep- ler was the first who conjectured that attrac- tion was the principal cause ; asserting, that the sphere of the moon's operation extended to the earth, and drew up its waters. The precise manner in which this is done, was discovered by Newton. The moon has been found, like all the rest of the planets, to attract, and to be attracted by the earth. This attraction prevails throughout our whole planetary system. The more matter there is contained in any body, the more it attracts : and its influence de- creases in proportion as the distance, when squared, increases. This being premised, Jet us see what must ensue upon supposing tl le moon in the meridian of any tract of the j sea. The surface of the water immediately under the moon is nearer the moon than any other part of the globe is ; and, therefore, must be more subject to its attraction than the waters any where else. The waters will, therefore, be attracted by the moon, and rise in a heap ; whose eminence will be the high- est where the attraction is greatest. In or- der to form this eminence, it is obvious that the surface, as well as the depths, will be agitated ; and that wherever the water runs from one part, succeeding waters must run to fill up the space it has left. Thus the waters of the sea, running from all parts, to attend the motion of the moon, produce the flowing of the tide ; and it is high tide at that part wherever the moon comes over it, or to its meridian. But when the moon travels onward, and ceases to point over the place where the wa- ters were just risen, the cause here of their rising ceasing to operate, they will flow back by their natural gravity, into the lower parts from whence they had travelled; and this retiring of the waters will form the ebbing of the sea. Thus the first part of the demonstration is obvious ; since, in general, it requires no great sagacity to conceive that the waters nearest the moon are most attracted, or rais- ed highest by the moon. But the other part of the demonstration, namely, how there come to be high tides at the same time, on the opposite side of the globe, and where the waters are farthest from the moon, is not so easy to conceive. To comprehend this, it must be observed, that the part of the earth and its waters that are farthest from the moon are the parts of all others that are least attracted by the moon : it must also be observed, that all the waters, when the moon is on the opposite side of the earth, must be attracted by it in the same direction that the earth itself attracts them ; that is, if I may so say, quite through the body of the earth, towards the moon itself. This, therefore, being conceived, it is plain that those waters which are farthest from the moon, will have less weight than those of any other part, on the same side of Ihe globe; because the moon's attraction, which conspires with the earth's attraction, is there least. Now. there- THE EARTH. 75 fore, the waters farthest from the moon, hav- ing less weight, and being lightest, will be pressed on all sides, by those that, having more attraction, are heavier; they will be pressed, I say, on all sides ; and the heavier waters (lowing in, will make them swell and rise in an eminence directly opposite to that on the other side of the globe, caused by the more immediate influence of the moon. In this manner the moon, in one diurnal re- volution, produces two tides; one raised im- mediately under the sphere of its influence, and the other directly opposite to it. As the moon travels, this vast body of waters rears upward, as if to watch its motions ; and pursues the same constant rotation. How- ever, in this great work of raising the tides, the sun has no small share ; it produces its own tides constantly every day, just as the moon does, but in much less degree, because the eun is at an immensely greater distance. Thus there are solar tides, and lunar tides. When the forces of these two great lumina- ries concur, which they always do when they are either in the same, or in opposite parts of the heavens, they jointly produce a much greater tide, than when they are so situated in the heavens, as each to make peculiar tides of their own. To express the very same thing technically ; in the conjunctions and oppositions of the sun and moon, the attrac- tion of the sun conspires with the attraction of the moon ; by which means the high spring tides are formed. But in the quadratures of the sun and moon, the water raised by the one is depressed by the other ; and hence the lower neap-tides have their production. In a word, the tides are greatest in the syzi- gies, and least in the quadratures. This theory well understood, and the as- tronomical terms previously known, it may readily be brought to explain the various ap- pearances of the tides, if the earth were co- vered with a deep sea, and the waters unin- fluenced by shoals, currents, straits, or tem- pests. But in every part of the sea, near the shores, the geographer must come in to cor- rect the calculations of the astronomer. For, by reason of the shallowness of some places, and the narrowness of the straits in others, there arises a great diversity in the effect. U not to be accounted for without an exact knowledge of all the circumstances of the place. In the great depths of the ocean, for instance, a very slow and imperceptible mo- tion of the whole body of water will suffice to raise its surface several feet high ; but if the same increase of water is to be conveyed through a narrow channel, it must rush through it with the most impetuous rapidity. Tims, in the English Channel, and the Ger- man Ocean, the tide is found to flow strong- est in those places that are narrowest ; the same quantity of water being, in this case, driven through a smaller passage. It is of- ten seen, therefore, pouring through a strait with great force ; and, by its rapidity, consi- derably raised above the surface of that par! of the ocean into which it runs. This shallowness and narrowness in many parts of the sea, give also rise to a peculiari- ty in the tides of some parts of the world. For in many places, and in our own seas in particular, the greatest swell of the tide i? not while the moon is in its meridian height, and directly over the place, but some time after it has declined from thence. The sea, in this case, being obstructed, pursues the moon with what despatch it can, but does not arrive with all its waters till long after the moon has ceased to operate. Lastly, from this shallowness of the sea, and from its be- ing obstructed by shoals and straits, we may account for the Mediterranean, the Baltic, and the Black Sea, having no sensible tides. These, though to us they seem very exten- sive, are not however large enough to be af- fected by the influence of the moon ; and as to their communication with the ocean, through such narrow inlets, it is impossible in a few hours they should receive and re- turn water enough to raise or depress them in any considerable degree. In general we may observe, that all tides are much higher, and more considerable in the torrid zone, than in the rest of the ocean ; the sea in those parts being generally deep- er, and less affected by changeable winds, or winding shores." The greatest tide we know of, is that at the mouth of the river Indus, where the water rises thirty feet in height. Bufibn, vol. ii. p. 1 87- 76 A HISTORY OF How great, therefore, must have been the amazement of Alexander's soldiers at so strange an appearance ! They who always before had been accustomed only to the scarcely perceptible risings of the Mediter- ranean, or the minute intumescence of the Black Sea, when made at once spectators of a river rising and falling thirty feet in a few hours, must no doubt have felt the most ex- treme awe, and, as we are told, a a mixture of curiosity and apprehension. The tides are also remarkably high on the coast of Malay, in the straits of Sunda, in the Red Sea, at the mouth of the river St. Lawrence, along the coasts of China and Japan, at Panama, and in the gulf of Bengal. The tides of Ton- quin, however, are the most remarkable in the world. In this part there is but one tide, and one ebb, in twenty-four hours ; whereas, as we have said before, in other places there are two. Besides, there, twice in each month there is no tide at all, when the moon is near the equinoctial, the water being for some time quite stagnant. These, with some other odd appearances attending the same phasno- mena, were considered by many as inscruta- ble ; but Sir Isaac Newton, with peculiar sa- gacity, adjudged them to arise from the con- currence of two tides, one from the South Sea, and the other from the Indian Ocean. Of each of these tides there come successive- ly two every day ; two at one time greater, and two at another that are less. The time between the arrival of the two greater, is considered by him as high tide ; the time between the two lesser, as ebb. In short, with this clue, that great mathematician solv- ed every appearance, and so established his theory, as to silence every opposer. This fluctuation of the sea from the tides, produces another, and more constant rota- tion of its waters, from the east to the west, in this respect following the course of the moon. This may be considered as one great and general current of the waters of the sea; and although it be not every where distin- guishable, it is nevertheless every where ex- istent, except when opposed by some parti- cular current or eddy, produced by partial and local causes. This tendency of the sea * Quintus Curtius. towards the west is plainly perceivable in all the great straits of the ocean ; as, for in- stance, in those of Magellan, where the tide running in from the east., rises twenty feei high, and continues flowing six hours; where- as the ebb continues but two hours, and the current is directed to the west This proves that the flux is not equal to the reflux ; and that from both results a motion of the sea westward, which is more powerful during the time of the flux than the reflux. But this motion westward has been sensi- bly observed by navigators, in their passage back from India to Madagascar, and so on to Africa. In the great Pacific Ocean also it is very perceivable : but the places where it is most obvious, are, as was said, in those straits which join one ocean to another. In the straits between the Maldivia islands, in the gulf of Mexico, between Cuba and Ju- catan. In the straits of the gulf of Paria, the motion is so violent, that it hath received the appellation of the Dragon's Mouth. North- ward in the sea of Canada, in Waigat's straits, in the straits of Java, and, in short, in every strait where the ocean on one part pours in- to the ocean on the other. In this manner, therefore, is the sea carried with an unceas- ing circulation round the globe; and, at the same time that its waters are pushed back and forward with the tide, they have thus a progressive current to the west, which though less observa>\e, is not the less real. Besides these two general motions of the sea, there are others which are particular to many parts of it, and are called currents. These are found to run in all directions, east, west, north, and south ; being formed, as was said above, by various causes; the promi- nence of the shores, the narrowness of the straits, the variations of the wind, and the in- equalities at the bottom. These, though no great object to the philosopher, as their causes are generally local and obvious, are nevertheless of the most material conse- quence to the mariner ; and, without a know- ledge of which, he could never succeed. It often has happened, that when a ship has unknowingly got into one of these, every thing seems to go forward with success, the mariners suppose themselves every hour ap- proaching their wished-for port, the wind fills THE EARTH. 77 their sails, and the ship's prow seems to di- vide the water ; but, at last, by miserable experience they find, that instead of going forward, they have been all the time reced- ing. The business of currents, therefore, makes a considerable article in navigation; and the direction of (heir stream, and their rapidity has been carefully set down. This some do by the observation of the surface of the current ; or by the driving of the froth along the shore ; or by throwing out what is called the log-line, with a buoy made for that purpose ; and by the direction and mo- tion of this, they judge of the setting, and the rapidity of the current. These currents are generally found to be most violent under the equator, where in- deed all the motions of the ocean are most perceivable. Along the coasts of Guinea, if a ship happens to overshoot the mouth of any river it is bound to, the current prevents its return ; so that it is obliged to steer out to sea, and take a very large compass, in order to correct the former mistake. These set in a contrary direction to the general motion of the sea westward ; and that so strongly, that a passage which with the current is made in two days, is with difficulty performed in six weeks against it. However, they do not ex- tend above twenty leagues from the coast : and ships going to the East Indies, take care not to come within the sphere of their action. At Sumatra, the currents, which are extreme- ly rapid, run from south to north ; there are also strong currents between Madagascar and the Cape of Good Hope. On the west- ern coasts of America, the current always runs from the south to the north, where a south wind, continually blowing, most proba- bly occasions this phaenomenon. But the currents that are most remarkable, and those continually flowing, into the Mediterranean sea, both from the ocean by the straits of Gibralter, and at its other extremity, from the Euxine sea by the Archipelago. This is one of the most extraordinary appear- ances in nature, this large sea receiving not only the numerous rivers that fall into it, such as the Nile, the Rhone, and the Po, but also a very great influx from the Euxine sea on one part, and the Ocean on the other. At the same time, it is seen to return none of those waters it is thus known to receive : outlets running from it there are none ; no rivers but such as bring it fresh supplies; no straits but what are constantly pouring their waters into it. It has therefore been the wonder of mankind in every age, how and by what means this vast concourse of waters are disposed of; or how this sea, which is always receiving, and never returning, is no way fuller than before. In order to account for this, some have said, that the water was re-conveyed by subterraneous passages into the Red Sea.* There is a story told of an Arabian caliph, who caught a dolphin in this sea, admiring the beauty of which, he let it go again, having previously marked it by a ring of iron. Some time after a dolphin was caught in the Red Sea, and quickly known by the ring to be the same that had been ta- ken in the Mediterranean before. Such, how- ever, as have not been willing to found their opinions upon a story, have attempted to ac- count for the disposal of the waters of the Mediterranean by evaporation. For this purpose they have entered into long calcula- tions upon the extent of its surface, and the quantity of water that would be raised from such a surface in a year. They then com- pute how much water runs in by its rivers and straits in that time ; and find, that the quantity exhausted by evaporation greatly ex- ceeds the quantity supplied by rivers and seas. This solution, no doubt, would be satisfactory, did not the Ocean, and the Euxine, evapo- rate as well as the Mediterranean : and as these are subject to the same drain, it must follow, that all the seas will in this respect be upon a par; and, therefore, there must be some other cause for this unperceived drain, and continual supply. This seems to be satisfactorily enough accounted for by Dr. Smith, who supposes an under current running through the straits of Gibraltar to carry out as much water into the Ocean, as the upper current continually carries in from it. To confirm this, he observes, that nearer home, between the north and south Ireland, the tide is known to run one way at top, and the ebb another way at bottom. This dou- ble current he also confirms by an expen- . - - -.-_!--_ iPl ... Kircher Mund. Subt. vol. i. 78 A HISTORY OF ment communicated to him by an able sea- man, who being with one of the king's fri- gates in the Baltic, found he went with his boat into the mid-stream, and was carried violently by the current ; upon which a bas- ket was sunk, with a large cannon ball, to a certain depth of water, which gave a check to the boat's motion ; as the basket sunk still lower, the boat was driven by the force of the water below against the upper current ; and the lower the basket was let down, the stronger the under current was fotfrid, and the quicker was the boat's motion against the upper stream, which seemed not to be above four fathom deep. Hence we may readily infer, that the same cause may operate at the straits of Gibraltar ; and that while the Me- diterranean seems replenishing at top, it may be emptying at bottom. The number of the currents at sea are im- possible to be recounted, nor, indeed, are they always known ; new ones are daily pro- duced by a variety of causes, and as quickly disappear. When a regular current is oppo- sed by another in a narrow strait, or where the bottom of the sea is very uneven, a whirlpool is often formed. These were for- merly considered as the most formidable ob- structions to navigation, and the ancient po- ets and historians speak of them vvitli terror; they are described as swallowing up ships, and dashing them against the rocks at the bottom : apprehension did no fail to add imaginary terrors to the description, ancl pla- ced at the centre of the whirlpool a dreadful den, fraught with monsters, whose howlings served to add new horrors to the dashings of the deep. Mankind at present, however, view these eddies of the sea with very little apprehension ; and some have wondered how the ancients could have so much over- charged their descriptions. But all this is very naturally accounted for. In those times when navigation was in its infancy, and the slightest concussion of the waves generally sent the poor adventurer to the bottom, it is not to be wondered at that he was terrified at the violent agitations in one of these. When his little ship, but ill fitted for oppos- ing the fury of the sea, was got within the vortex, there was then no possibility of ever returning. To add to the fatality, they were always near the shore ; and along the shore was the only place where this ill-provided mariner durst venture to sail. These were therefore dreadful impediments to his navi- gation ; for if he attempted to pass between I hem and the shore, he was sometimes suck- ed in by the eddy; and if he attempted to avoid them out at sea, he was often sunk by the storm. But in our time, and in our pre- sent improved state of navigation, Charybdis, and the Euripus, with all the other irregular currents of the Mediterranean, are no long- er formidable. Mr. Addison, not attending to this train of thinking, upon passing through the straits of Sicily, was surprised at the lit- tle there was of terror in the present appear- ance of Scylla and Charybdis; and seems to be of opinion, that their agitations are much diminished since the times of antiquity. In fact, from the reasons above, all the wonders of the Mediterranean Sea are described in much higher colours than they merit, to us who are acquainted with the more magnifi- cent terrors of the Ocean. The Mediterra- nean is one of the smoothest and most gentle seas in the world ; its tides are scarcely per- ceivable, except in the gulf of Venice, and shipwrecks are less known there than in any other part of the world. It is in the Ocean, therefore, that these whirlpools are particularly dangerous, where the tides are violent, and the tempests fierce. To mention only one, that called the Maels- troom, upon the coasts of Norway, which is considered as the most dreadful and vora- cious in the world. - The name it has receiv- ed from the natives, signifies the navel of the sea, since they suppose that a great share of the water of the sea is sucked up and dis- charged by its vortex. A minute descrip- tion of the internal parts is not to be expect- ed, since none who were there ever returned to bring back information. The body of the waters 'that form this whirlpool, are extended in a circle above thirteen miles in circumfer- ence." In the midst of this stands a rock, against which the tide in its ebb is dashed with inconceivable fury. At this time it in- stantly swallows up all tilings that come with- in the sphere of its violence, trees, timber, Kircher Mund. Subt. vol. i. p. 15G. THE EARTH. 79 and shipping. No skill in the mariner, nor strength of rowing, can work an escape : the sailor at the helm finds the ship at first go in a current opposite to his intentions ; his ves- sel's motion, though slow in the beginning, becomes every moment more rapid ; it goes round in circles still narrower and narrower, till at last it is dashed against the rocks, and instantly disappears ; nor is it seen again for six hours : till the tide flowing, it is vomited forth with the same violence with which it was drawn in. The noise of this dreadful vortex still farther contributes to increase its terror, which, with the dashing of the waters, and the dreadful valley, if it may be so called, caused by their circulation, makes one of the most tremendous objects in nature. CHAPTER XVII. OF THE CHANGES PRODUCED BY THE SEA UPON THE EARTH. FROM what has been said, as well of the earth as of the sea, they both appear to be in continual fluctuation. The earth, the common promptuary that supplies subsist- ence to men, animals, and vegetables, is con- tinually furnishing its stores to their support. But the matter which is thus derived from it, is soon restored and laid down again to be prepared for fresh mutations. The trans- migration of souls is no doubt false and whim- sical ; but nothing can be more certain than the transmigration of bodies : the spoils of the meanest reptile may go to the formation of a prince ; and, on the contrary, as the po- et has it, the body of Caesar may be employ- ed in stopping a beer-barrel. From this, and other causes, therefore, the earth is in con- tinual change. Its internal fires, the devia- tion of its rivers, and the falling of its moun- tains, are daily altering its surface ; and geo- graphy can scarcely recollect the lakes and the valleys that history once described. But these changes are nothing to the in- stability of the ocean. It would seem that inquietude was as natural to it as its fluidity. It is first seen with a constant and equable motion going towards the west; the tides then interrupt this progression, and for a time drive the waters in a contrary direction ; beside these agitations, the currents act their part in a smaller sphere, being generally greatest where the other motions of the sea are least ; namely, nearest the shore : the winds also contribute their share in this uni- versal fluctuation : so that scarcely any part of the sea is wholly seen to stagnate. Nil enim quiescii, widis impellitur undo, Et spiritua et calor toto se corpore miscent. As this great element is thus changed, and continually labouring internally, it may be readily supposed that it produces correspond- ent changes upon its shores, and those parts of the earth subject to its influence. In fact, it is every day making considerable altera- tions, either by overflowing its shores in one place, or deserting them in others : by cover- ing over whole tracts of country, that were cultivated and peopled, at one time ; or by leaving its bed to be appropriated to the purposes of vegetation, and to supply a new theatre for human industry at another. In this struggle between the earth and the sea for dominion, the greatest number of our shores seem to defy the whole rage of the waves, both by their height, and the rocky materials of which they are composed. The coasts of Italy, for instance, a are bordered with rocks of marble of different kinds, the quarries of which may easily be distinguished at a distance from sea, and appear like per- pendicular columnsof the most beautiful kinds of marble, ranged along the shore. In gene- ral, the coasts of France, from Brest to Bordeaux, are composed of rocks; as are also those of Spain and England, which de- Buffon, vol. ii. p. 199- 80 A HISTORY OF fend the land, and only are interrupted here and there to give an egress to rivers, and to grant the conveniences of bays and harbours to our shipping. It may be in general re- marked, that wherever the sea is most vio- lent and furious, there the boldest shores, and of the most compact materials, are found to oppose it. There are many shores several hundred feet perpendicular, against which the sea, when swollen with tides, or storms, rises and beats with inconceivable fury. In "the Orkneys, where the shores are thus form- ed, it sometimes, when agitated by a storm, rises two hundred feet perpendicular, and dashes up its spray, together with sand, and other substances that compose its bottom, upon land, like showers of rain. Hence, therefore, we may conceive how the violence of the sea, and the boldness of the shore, may be said to have made each other. Where the sea meets no obstacles, it spreads its waters with a gentle intume- scence, till all its power is destroyed, by wanting depth to aid the motion. But when its progress is checked in the midst, by the prominence of rocks, or the abrupt elevation of the land, it dashes with all the force of its depth against the obstacle, and forms, by its repeated violence, that abruptness of the shore which confines its impetuosity. Where the sea is extremely deep, or very much vex- ed by tempests, it is no small obstacle that can confine its rage ; and for this reason we see the boldest shores projected against the deepest waters; all less impediments having long before been surmounted and washed away. Perhaps of all the shores in the world, there is not one so high as that on the west of St. Kilda, which, upon a late admeasure- ment, 1 ' was found to be six hundred fathom perpendicular above the surface of the sea. Here, also, the sea is deep, turbulent, and stormy ; so that it requires great force in the shore to oppose its violence. In many parts of the world, and particularly upon the coasts of the East Indies, the shores, though not high above water, are generally very deep, and consequently the waves roll against the land with great weight and irregularity. This rising of the waves against the shore, is * BufTon, vol. ii. p. 191. b Description of St. Kilda. called by mariners the surf of the sea; and in shipwrecks is generally fatal to such as attempt to swim on shore. In this case, no dexterity in the swimmer, no float he can use, neither swimming girdle nor cork jacket will save him; the weight of the superincum- bent waves breaks upon him at once, and crushes him with certain ruin. Some few of the natives, however, have the art of swim- ming and of navigating their little boats near those shores, where an European is sure of instant destruction. In places where the force of the sea is less violent, or its tides less rapid, the shores are generally seen to descend with a more gra- dual declivity. Over these, the waters of the tide steal by almost imperceptible degrees, covering them for a large extent, and leav- ing them bare on its recess. Upon these shores, as was said, the sea seldom beats with any great violence, as a large wave has not depth sufficient to float it onwards; so that here only are to be seen gentle surges making calmly towards land, and lessening as they approach. As the sea, in the former description, is generally seen to present pros- pects of tumult and uproar, here it more usu- ally exhibits a scene of repose and tranquil beauty. Its waters, which when surveyed from the precipice, afforded a muddy greenish hue, arising from their depth and position to the eye, when regarded from a shelving shore, wear the colour of the sky, and seem rising to meet it. The deafening noise of the deep sea is here converted into gentle mur- murs ; instead of the water's dashing against the face of the rock, it advances and recedes, still going forward, but with just force enough i to push its weeds and shells, by insensible | approaches, to the shore. There are other shores, beside those al- ready described, which either have been raised by art to oppose the sea's approaches, or, from the sea's gaining ground, are threat- ened with imminent destruction. The sea's being thus seen to give and take away lands at pleasure, is, without question, one of the most extraordinary considerations in all na- tural history. In some places it is seen to obtain the superiority by slow and certain Newton's Optics, p. 163 167- THE EARTH. approaches ; or to burst in at once, and over- whelm all things in undistinguished destruc- tion; in other places it departs from its shores, and where its waters have been known to rage, it leaves fields covered with the most beautiful verdure. The formation of new lands, by the sea's continually bringing its sediment to one place, and by the accumulation of its sands in ano- ther, is easily conceived. We have had ma- ny instances of this in England. The island of Oxney, which is adjacent to Romney marsh, was produced in this manner. This had for a long time been a low level, conti- nually in danger of being overflown by the ri- ver Rother ; but the sea, by its depositions, has gradually raised the bottom of the river, while it has hollowed the mouth ; so that the one is sufficiently secured from inundations, and the other is deep enough to admit ships of considerable burthen. The like also may be seen at that bank called the Dogger-sands, where two tides meet, and which thus re- ceives new increase every day, so that in time the place seems to promise fair for be- ing habitable earth. On many parts of the coasts of France, England, Holland, Germa- ny, and Prussia, the sea has been sensibly known to retire. 8 Hubert Thomas asserts, in his Description of the country of Liege, that the sea formerly encompassed the city of Tongres, which, however, is at present thirty-five leagues distant from it : this asser- tion he supports by many strong reasons ; and among others, by the iron rings fixed in the walls of the town, for fastening the ships that came into the port. In Italy there is a considerable piece of ground gained at the mouth of the river Arno; and Ravenna, that once stood by the sea side, is now consider- ably removed from it. But we need scarce- ly mention these, when we find that the whole republic of Holland seems to be a conquest upon the sea, and in a manner rescued from its bosom. The surface of the earth, in this country, is below the level of the bed of the sea : and I remember, upon approaching the coast, to have looked down upon it from the sea, as into a valley ; however, it is every day rising higher by the depositions made * BufTon, vol. vi. p. 424. upon il by the sea, the Rhine, and the Meuse ; and those parts which formerly admitted large men of war, are now known to be too shallow to receive ships of very moderate burthen. b The province of Jucatan, a penin- sula in the gulf of Mexico, was formerly a part of the sea ; this tract, which stretches out into the ocean, a hundred leagues, and which is above thirty broad, is every where, at a moderate depth below the surface, com- posed of shells, which evince that its land once formed the bed of the sea. In France, the town of Aigues Mortes was a port in the times of St. Louis, which is now removed more than four miles from the sea. Psalmodi, in the same kingdom, was an island in the year 815, but is now more than six miles from the shore. All along the coasts of Nor- folk, I am very well assured, that in the mr- mory of man, the sea has gained fifty yards in some places, and has lost as much in others. Thus numerous, therefore, are the instan- ces of new lands having been produced from the sea, which, as we see, is brought about two different ways : first, by the waters rais- ing banks of sand and mud where their sedi- ment is deposited : and secondly, by their relinquishing the shore entirely, and leaving it unoccupied to the industry of man. But as the sea has been thus known to re- cede from some lands, so has it, by fatal ex- perience,been found to encroach upon others; and, probably, these depredations on one part of the shore, may account for their de- reliction from another ; for the current which rested upon some certain bank, having got an egress in some other place, it no longer presses upon its former bed, but pours all its stream into the new entrance, so that every inundation of the sea may be attended with some correspondent dereliction of another shore. However this be, we have numerous his- tories of the sea's inundations, and its bury- ing whole provinces in its bosom. Many countries that have been thus destroyed bear melancholy witness to the truth of history ; and show the tops of their houses, and the spires of their steeples, still standing at the b Burton, vol. vi. p. 424 82 A HISTORY OF bottom of the water. One of the most con- siderable inundations we have in history, is that which happened in the reign of Henry I. which overflowed the estates of the Earl Godwin, and forms now that bank called the Goodwin Sands. In the year 1546, a similar irruption of the sea destroyed a hundred thou- sand persons in the territory of Dort; and yet a greater number round Dullart. In Friez- land, and Zealand, there were more than three hundred villages overwhelmed ; and their remains continue still visible at the bot- tom of the water in a clear day. The Baltic Sea has, by slow degrees, covered a large part of Pomerania ; and, among others, de- stroyed and overwhelmed the famous port of Vineta. In the same manner, the Norwegian Sea has formed several little islands from the main land, and still daily advances upon the continent. The German Sea has advanced upon the shores of Holland, nearCatt; so that the ruins of an ancient citadel of the Romans, which was formerly built upon this coast, are now actually under water. To these accidents several more might be added ; our own historians, and those of other coun- tries, abound with them; almost every flat shore of any extent being able to show some- thing that it has lost, or something that it has gained from the sea. There are some shores on which the sea has made temporary depredations ; where it has overflowed, and after remaining perhaps some ages, it has again retired of its own accord, or been driven back by the industry of man." There are many lands in Norway, Scotland, and the Maldivia islands, that are at one time covered with water, and at ano- ther free. The country round the Isle of Ely, in the times of Bedc, about a thousand years ago, was one of the most delightful spots in the whole kingdom. It was not only richly cultivated, and produced all the neces- saries of life, but grapes also that afforded excellent wine. The accounts of that time are copious in the description of its verdure and fertility ; its rich pastures, covered with flowers and herbage; its beautiful shades, and wholesome air. But the sea breaking in upon the land, overwhelmed the whole coun- 1 Buffon, vol. ii. p. 425. try, took possession of the soil, and totally destroyed one of the most fertile valleys in the world. Its air, from being dry and health- ful, from that time became most unwhole- some, and clogged with vapours; and the small part of the country that, by being higher than the rest, escaped the deluge, was soon rendered uninhabitable, from its noxious vapours. Thus this country con- tinued under water for some centuries; till, at last, the sea, by the same caprice which had prompted its invasions, began to aban- don the earth in like manner. It has con- tinued for some ages to relinquish its former conquests; and although the inhabitants can neither boast the longevity, nor the luxuries of their former preoccupants, yet they find ample means of subsistence ; and if they hap- pen to survive the first years of their resi- dence there, they are often known to arrive at a good old age. But although history be silent as vo many other inundations of the like kind, where the sea has overflowed the country, and after- wards retired, yet we have numberless testi- monies of another nature, that prove it be- yond the possibility of a doubt : I mean those numerous trees that are found buried at considerable depths in places where either rivers or the sea has accidentally overflown. 1 ' At the mouth of the river Ness, near Bruges, in Flanders, at the depth of fifty feet, are found great quantities of trees lying as close to each other as they do in a wood : the trunks, the branches, and the leaves, are in such perfect preservation, that the particular kind of each tree may instantly be known. About five hundred years ago, this very ground was known to have been covered by the sea; nor is there any history or tradition of its having been dry ground, which we can have no doubt must have been the case. Thus we see a country flourishing in verdure, producing large forests, and trees of various kinds, overwhelmed by the sea. We see this element depositing its sediment to a height of fifty feet; and its waters must, therefore, have risen much higher. We see the same, after it hathus overwhelmed and sunk the land so deep beneath its slime, capriciously b Buffon, vol. ii. p. 403. THE EARTH. retiring from the same coasts, and leaving that habitable once more, which it had for- merly destroyed. All this is wonderful; and, perhups, instead of attempting to inquire after the cause, which has hitherto been inscru- table, it will best become us to rest satisfied with admiration. At the city of Modena in Italy, and about four miles round it, wherever it is dug, when the workmen arrive at the depth of sixty-three feet, they come to a bed of chalk, which they bore with an augre five feet deep : they then withdraw from the pit, before the augre is removed, and upon its extraction, the water bursts up through the aperture with great violence, and quickly fills this new-made well, which continues full, and is affected neither by rains nor droughts. But that which is most remarkable in this operation, is the layers of earth as we descend. At the depth of fourteen feet, are found the ruins of an ancient city, paved streetf, houses, floors, and different pieces of Mosaic. Under this is found a solid earth, that would induce one to think had never been removed ; however, under it is found a soft oozy earth, made up of vegetables ; and at twenty-six feet depth, large trees entire, such as walnut-trees, with the walnuts still sticking on the stem, and their leaves and branches in exact preserva- tion. At twenty-eight feet deep, a soft chalk is found, mixed with a vast quantity of shells; and this bed is eleven feet thick. Under this, vegetables are found again, with leaves and branches of trees as before ; and thus alter- nately chalk and vegetable earth to the depth of sixty-three feet. These are the layers wherever theworkmen attempt to bore; while in many of them, they also find pieces of charcoal, bones, and bits of iron. From this description, therefore, it appears, that this country has been alternately overflowed and deserted by the sea, one age after another : nor were these overflowings and retirings of trifling depth, or of short continuance. When the sea burst in, it must have been a long time in overwhelming the branches of the fallen forest with its sediments ; and still longer in forming a regular bed of shells ele- ven feet over them. It must have, therefore, taken an age, at least, to make any one of these layers; and we may conclude, that it must have been many ages employed in the production of them all. The land, also, upon being deserted, must have had time to grow compact, to gather fresh fertility, arid to bo drained of its waters before it could be dis- posed to vegetation ; or before its trees could have shot forth again to maturity. We have instances nearer home of thr same kind, given us in the Philosophical Transactions ; one of them by Mr. Derham. An inundation of the sea at Dagenham, in Essex, laying bare a part of the adjacent pasture, for above two hundred feet wide, and, in some places, twenty deep, it discover- ed a number of trees that had lain there for many ages before; these trees, by laying long under ground, were become black and hard, and their fibres so tough, that one might as easily break a wire, as any of them : they lay so thick in the place where they were found, that in many parts he could step from one to another : he conceived, also, that not only all the adjacent marshes, for several hundred acres, were covered underneath with such timber, but also the marshes along the mouth of the Thames, for several miles, The meeting with these trees, at such depths, he ascribes to the sediment of the river, and the tides, which constantly washing over them, have always left some part of their sub- stance behind, so as, by repeated alluvions, to work a bed of vegetable earth over them, to the height at which he found it. The levels of Hatfield-Chace, in Yorkshire, a tract of above eighteen thousand acres, which was yearly overflown, was reduced to arable and pasture land, by one Sir Cornelius Vermusden, a Dutchman. At the bottom of this wide extent, are found millions of the roots and bodies of trees, of such as this isltyid either formerly did, or does at present pro- duce. The roots of all stand in their proper postures ; and by them, as thick as ever they could grow, the respective trunks of each, some above thirty' yards long. The oaks, some of which have been sold for fifteen pounds apiece, are as black as ebony, very lasting, and close grained. The ash-trees are as soft as earth, and are commonly cut in pieces by the workmen's spades, and as soon as flung up into the open air, turn to dust. But all the rest, even the willows A HISTORY OF themselves, which are softer than the ash, preserve their substance and texture to this very day. Some of the firs appear to have vegetated, even after they were fallen, and to have, from their branches, struck up large trees, as great as the parent trunk. It is ob- servable, that many of these trees have been burnt, some quite through, some on one side, Borne have been found chopped and squared, others riven with great wooden wedges, all sufficiently manifesting, that the country which was deluged, had formerly been inhabited. Near a great root of one tree were found eight coins of the Roman emperors; and in some places, the marks of the ridge and fur- row were plainly perceivable, which testified that the ground had formerly been patient of cultivation. The learned naturalist who has given this description," has pretty plainly evinced, that this forest, in particular, must have been thus levelled by the Romans ; and that the falling of the trees must have contributed to the ac- cumulation of the waters. " The Romans," says he, " when the Britons fled, always pur- sued them into the fortresses of low woods, and miry forests : in these the wild natives found shelter; and, when opportunity offered, issued out, and fell upon their invaders with- out mercy. In this manner, the Romans were at length so harassed, that orders were issued out for cutting down all the woods and forests in Britain. In order to effect this, and destroy the enemy the easier, they set fire to the woods composed of pines, and other inflam- mable timber, which spreading, the conflagra- tion destroyed not only the forest, but infinite numbers of the wretched inhabitants who had taken shelter therein. When the pine-trees had thus done what mischief they could, the Romans then brought their army nearer, and, with whole legions of the captive Britons, cut down most of the trees that were yet left standing ; leaving only here and there some great trees untouched, as monuments of their fury. These, unneedful of their labour, being destitute of the support of the underwood, and of their neighbouring trees, were easily overthrown by the winds, and, without inter- ruption, remained on the places where they Phil. Trans, vol. iv. part ii. p. 214. happened to fall. The forest thus fallen, must necessarily have stopped up the currents, both from land and sea; and turned into great lakes, what were before but temporary streams. The working of the waters here, the consumption and decay of rotten boughs and branches, and the vast increase of water- moss which flourishes upon mars-hy grounds, soon formed a covering over the trunks of the fallen trees, and raised the earth several feet above its former level. The earth thus every day swelling, by a continual increase from the sediment of the waters, and by the light- ness of the vegetable substances of which it was composed, soon overtopt the waters by which this intumescence was at first effected ; so that it entirely got rid of its inundations, or only demanded a slight assistance from man for that purpose." This may be the origin of all bogs, which are formed by the putrefaction of vegetable substances, mixed with the mud and slime deposited by waters, and at length acquiring a sufficient con- sistency. From this we see what powerful effects the sea is capable of producing upon its shores, either by overflowing some or deserting others; by altering the direction of these, and rendering those craggy and precipitate, which before were shelving. But the influence it has upon these is nothing to that which it has upon that great body of earth which forms its bottom. lit is at the bottom of the sea that the greatest wonders are performed, and the most rapid changes are produced ; it is there that the motion of the tides and the currents have their whole force, and agitate the substances of which their bed is com- posed. But all these are almost wholly hid from human curiosity : the miracles of the deep are performed in secret; and we have but little information from its abysses, except what we receive by inspection at very shal- low depths, or by the plummet, or from divers, who are known to descend from twenty to thirty fathom. 11 The eye can reach but a very short way into the depths of the sea; and that only when its surface is glassy and serene. In many seas it perceives nothing but a bright 11 fhil. Trans, vol. iv. part ii. p. lP r ., THE EARTH. 85 sandy plain at bottom, extending for several hundred miles, without an intervening object. But in others, particularly in the Red Sea, it is very different : the whole bottom of this extensive hed of waters is, literally speaking, a forest of sub-marine plants, and corals form- ed by insects for their habitation, sometimes branching out to a great extent. Here are seen the madrepores, the sponges, mosses, sea- mushrooms, and other marine productions, covering every part of the bottom ; so that some have even supposed the sea to have taken its name from the colour of its plants below. However, these plants are by no means peculiar to this sea, as they are found in great quantities in the Persian gulf, along the coast of Africa, and those of Provence and Catalonia. The bottom of many parts of the sea near America presents a very different, though a very beautiful appearance. This is covered with vegetables, which make it look as green as a meadow, and beneath are seen thousands of turtles, and other sea-animals, feeding thereon. In order to extend our knowledge of the sea to greater depths, recourse has been had to the plummet ; which is generally made of a lump of lead of about forty pounds weight, fastened to a cord." This, however, only an- swers in moderate depths; for when a deep sea is to be sounded, the matter of which the cord is composed, being lighter than the water, floats upon it, and when let down to a considerable depth, its length so increases its surface, that it is often sufficient to prevent the lead from sinking; so that this may be the reason why some parts of the sea are said to have no bottom. In general, we learn from the plummet, that the bottom of the sea is tolerably even where it has been examined ; and that the farther from the shore, the sea is in general the deeper. Notwithstanding, in the midst of a great and unfathomable ocean, we often find an island raising its head, and singly braving its fury. Such islands may be con- sidered as the mountains of the deep ; and, could we for a moment imagine the waters of the ocean removed, or dried away, we Boyle, vol. ii. p 5. should probably find the inequalities of its bed resembling those that are found at land. Here extensive plains ; there valleys ; and, in many places, mountains of amazing height. M. Buache has actually given us a map of that part of its bottom, which lies between Africa and America, taken from the several sound- ings of mariners : in it we find the same un- even surface that we do upon land, the same eminences,and the same depressions. In such an imaginary prospect, however, there would be this difference, that as the tops of land- mountains appear the most barren and rocky, the tops of sea-mountains would be found the most verdant and fruitful. The plummet, which thus gives us some idea of the inequalities of the bottom,leaves us total- ly in the dark as to every other particular; recourse, therefore, has been had to divers : these, either being bred up in this dangerous way of life, and accustomed to remain some time under water without breathing, or assist- ed by means of a diving-bell, have been able to return some confused and uncertain ac- counts of the places below. In the great diving- bell improved by Dr. Halley, which was large enough to contain five men, and was sup- plied with fresh air by buckets, that alternate- ly rose and fell, they descended fifty fathom. In this huge machine, which was let down- from the mast of the ship, the doctor himself went down to the bottom, where, when the sea was clear, and especially when the sun shone, he could see perfectly well to write or read, and much more to take up any thing that was underneath : at other times, when the water was troubled and thick, it was as dark as night below, so that he was obliged to keep a candle lighted at the bottom. But there is one thing very remarkable ; that the water, which from above was usually seen of a green colour, when looked at from below, appeared to him of a very different one, cast- ing a redness upon one of his hands, like that of damask roses b a proof of the sea's taking its colour not from any thing floating in it, but from the different reflexion* of the rays of light. Upon the whole, the accounts we have received from the bottom, by this contrivance, are but few. We learn from it, and from b Newton's Optics, p. 56. X* 86 A HISTORY OF divers in general, that while the surface of the sea may be deformed by tempests, it is usually calm and temperate below ;" that some divers who have gone down when the wea- ther was calm, and came up when it was tem- pestuous, were surprised at their not per- ceiving the change at the bottom. This, how- ever, must not be supposed to obtain with regard to the tides and the currents, as they are seen constantly shifting their bottom ; taking their bed with great violence from one place, and depositing it upon another. We are informed, also, by divers, that the sea grows colder in proportion as they descend to the bottom ; that as far as the sun's rays pierce, it is influenced by their warmth ; but lower, the cold becomes almost intolerable. A person of quality, who had been himself a diver, as Mr. Boyle informs us, declared, that though he seldom descended above three or four fathoms, yet he found it so much colder than near the top, that he could not well en- dure it; and that being let down in a great diving-bell, although the water could not im- mediately touch him, he found the air ex- tremely cold upon his first arrival at the bottom. From divers also we learn, that the sea, in many places, is filled with rocks at bottom ; and that, among their clefts, and upon their sides, various substances sprout forward, which are either really vegetable, or the nests of insects, increased to some magnitude. Some of these assume the shape of beautiful flowers; and though soft, when taken up, soon harden, and are kept in the cabinets of the curious. But of all those divers who have brought us information from the bottom of the deep, the famous Nicola Pesce, whose performances are told us by Kircher, is the most celebrated. I will not so much as pretend to vouch for the veracity of Kircher's account, which he as- sures us he had from the archives of the kings of Sicily ; but it may serve to enliven a heavy chapter. " In the times of Frederic, king of Sicily, there lived a celebrated diver, whoso name was Nicolas, and who, from his amazing skill in swimming, and his persever- ance under water, was surnamed the Fish. This man had, from his infancy, been used to Boyle, vol. iii. p. 242. the sea ; and earned his scanty subsistence by diving for corals and oysters ; which he sold to the villagers on shore. His long acquaint- ance with the sea, at last, brought it to be almost his natural element. He frequently was known to spend five days in the midst of the waves, without any other provisions than the fish which he caught there, and ate raw. He often swain over from Sicily to Ca- labria, a tempestuous and dangerous passage, carrying letters from the king. He was fre- quently known to swim among the gulfs of the Lipari islands, no way apprehensive of danger. " Some mariners out at sea, one day ob- served something at some distance from them, which they regarded as a sea-monster; but, upon its approach, it was known to be Ni- colas, whom they took into their ship. When they asked him whither he was going in so stormy and rough a sea, and at such a dis- tance from land, he showed them a packet of letters, which he was carrying to one of the towns of Italy, exactly done up in a leather bag, in such a manner as that they could not be wetted by the sea. He kept them thus company for some time on their voyage, con- versing and asking questions; and after eat- ing a hearty meal with thein^ he took his leave, and jumping into the sea, pursued his voyage alone. " In order to aid these powers of enduring in the deep, nature seemed to have assisted him in a very extraordinary manner ; for the spaces between his fingers and toes were webbed, as in a. goose; and his chest became so very capacious, that he could take in, at one inspiration, as much breath as would serve him for a whole day. " The account of so extraordinary a per- son did not fail to reach the king himself; who, actuated by the general curiosity, or- dered that Nicolas should be brought be- fore him. It was no easy matter to find Ni- colas, who generally spent his time in the solitudes of the deep; but at last, however, after much searching, he was found, and brought before his majesty. The curiosity of this monarch had been -long excited by the accounts he had heard of the bottom of the gulf of Ch-uybdis; he therefore con- ceived that it would be a proper opportunity THE EARTH. 87 to have more certain information; and com- manded our poor diver to examine the bot- tom of this dreadful whirlpool : as an incite- ment to his obedience, he ordered a golden cup to be flung into it. Nicolas was not in- sensible of the danger to which he was ex- posed ; dangers best known only to himself; and he therefore presumed to remonstrate : but the hopes of the reward, the desire of pleasing the king, and the pleasure of show- ing his skill, at last prevailed. He instantly jumped into the gulf, and was swallowed as instantly up in its bosom. He continued for three quarters of an hour below ; during which time the king and his attendants re- mained upon shore anxious for his fate ; but he at last appeared, buffeting upon the sur- face, holding the cup in triumph in one hand, and making his way good among the waves with the other. It may be supposed he was received with applause, upon his arrival on shore ; the cup was made the reward of his adventure ; the king ordered him to be taken proper care of; and, as he was somewhat fatigued and debilitated by his labour, after a hearty meal he was put to bed, and permit- ted to refresh himself by sleeping. " When his spirits were thus restored, he was again brought to satisfy the king's curi- osity with a narrative of the wonders he had seen; and his account was to the following effect : He would never, he said, have obey- ed the king's commands, had he been ap- prized of half the dangers that were before him. There were four things, he said, that rendered the gulf dreadful, not only to men, but even to the fishes themselves : first, the force of the water bursting up from the bot- tom, which requires great strength to resist ; secondly, the abruptness of the rocks, that on everyside threatened destruction; thirdly, the force of the whirlpool, dashing against those rocks ; and fourthly, the number and magni- tude of the polypous fish, some of which ap- peared as large as a man, and which, every where sticking against the rocks, projected their fibrous arms to entangle him. Being asked how he was able so readily to find the cup that had been thrown in, he replied, that it happened to be flung by the waves into the cavity of a rock, against which he liimself was urged in his descent. This account, however, did not satisfy the king's curiosity : being requested to venture once more inte the gulf for further discoveries, he at first re- fused ; but the king, desirous of having the most exact information possible of all things to be found in the gulf, repeated his solicita- tions; and, to give them still greater weight, produced a larger cup than the former, and added also a purse of gold. Upon these considerations, the unfortunate Pessacola once again plunged into the whirlpool, and was never heard of more." CHAPTER XVHI. A SUMMARY ACCOUNT OF THE MECHANICAL PROPERTIES OF AIR, HAVING described the earth and the sea, we now ascend into that fluid which surrounds them both ; and which, in some measure, sup- ports and supplies all animated nature. As, upon viewing the bottom of the ocean from its surface, we see an infinity of animals moving therein, and seeking food ; so, were some su perior being to regard the earth at a pro- per distance, he might consider us in the same light : he might, from his superior station, be- hold a number of busy little beings, immersed in the aerial fluid, that every where surrounds them, and sedulously employed in procuring the means of subsistence. This fluid, though too fine for the gross perception of its in- habitants, might, to his nicer organs of sight, be very visible; and, while he at once saw into its operations, he might smile at the va- rieties of human conjecture concerning it : he might readily discern, perhaps, the height above the surface of the earth to which this fluid atmosphere reaches : he might exactly A HISTORY OF determine the peculiar form of its parts which fl gives it the spring or elasticity with which it is endued : he might distinguish which of its ; parts were pure incorruptible air, and which only made for a little time to assume the ap- pearance, so as to be quickly returned back to the element from whence it came. But as for us, who are immersed at the bottom of this gulf, we must be contented with a more con- fined knowledge; and. wanting a proper point of prospect, remain satisfied with a combina- tion of the effects. One of the first things that our senses in- form us of is, that although the air is too fine ' for our sight, it is very obvious to our touch. Although we cannot see the wind contained in a bladder, we can very readily feel its re- sistance ; and though the hurricane may want j colour, we often fatally experience that it does not want force. We have equal expe- rience of the air's spring or elasticity : the [ bladder, when pressed, returns again, upon the pressure being taken away; a bottle, when filled, often bursts, from the spring of air which is included. So far the slightest experience reaches; but, by carrying experiment a little farther, we learn that air also is heavy : a round glass vessel being emptied of its air, and accurate- ly weighed, has been found lighter than when it was weighed with the air in it. Upon com- puting the superior weight of the full vessel, a cubic foot of air is found to weigh some- thing more than an ounce. From this experiment, therefore, we learn, that the earth, and all things upon its surface, are every where covered with a ponderous fluid, which rising very high over our heads, must be proportionably heavy. For instance, as in the sea, a man at the depth of twenty feet sustains a greater weight of water, than a man at the depth of but ten feet ; so will a man at the bottom of a valley have a greater weight of air over him, than a man on the top of a mountain. From hence we may conclude, that we sustain a very great weight of air; and al- though, like men walking at the bottom of the sea, we cannot feel the weight which presses equally round us, yet the pressure is not the less real. As in morals, we seldom know the blessings that surround us till we are deprived of them 5 so here we do not per- ceive the weight of the ambient fluid till a a part of it is taken away. If, by any means, we contrive to take away the pressure of the air from any one part of our bodies, we are soon made sensible of the weight upon the other parts. Thus, if we clap our hand upon the mouth of a vessel from whence the air lias been taken away, there will thus be air on one side, and none on the other; upon which we shall instantly find the hand vio- lently sucked inwards ; which is nothing more than the weight of the air upon the back of the hand that forces it into the space which, is empty below. As, by this experiment, we perceive that the air presses with great weight upon every thing on the surface of the earth, so by other experiments we learn the exact weight with which it presses. First, if the air be exhaust- ed out of any vessel, a drinking vessel for instance," arid tliis vessel be set with the mouth downwards in water, the water will rise up into the empty space, and fill the in- verted glass; for the external air will, in this case, press up the water where there is no weight to resist ; as, one part of a bed being pressed, makes the other parts, that have no weight upon them, rise. In this case, as was said, the water being pressed without, will rise in the glass; and would continue to rise (if the empty glass were tall enough) thirty- two feet high. In fact, there have been pipes made purposely for this experiment of above thirty-two feet high; in which, upon being exhausted, the water has always risen to the height of thirty-two feet : there it has always rested, and never ascended higher. From this, therefore, we learn, that the weight of the air which presses up the water, is equal to a pillar or column of water which is thirty- two feet high; as it is just able to raise such a column, and no more. In other words, the surface of the earth is every where covered with a weight of air, which is equivalent to a covering of thirty-two feet deep of water; or to a weight of twenty-nine inches and a half of quicksilver, which is known to be just as heavy as the former. This may be done by burning a bit of paper in the same, and then quickly turning it down upon the water. THE EARTH. 89 Thus we see that the air at the surface of the earth is just as heavy as thirty-two feet of water, or twenty-nine inches and a half of quicksilver ; and it is easily found, by com- putation, that to raise water thirty-two feet will require a weight of fifteen pounds upon every square inch. Now, if we are fond of computations, we have only to calculate how many square inches are in the surface of an ordinary human body, and allowing every inch to sustain fifteen pounds, we may amaze ourselves at the weight of air we sustain. It has been computed, and found, that our or- dinary load of air amounts to within a little of forty thousand pounds : this is wonderful ! but wondering is not the way to grow wise. Notwithstanding this be our ordinary load, and our usual supply, there are at different times very great variations. The air is not, like water, equally heavy at all seasons ; but sometimes is lighter and sometimes more heavy. It is sometimes more compressed, and sometimes more elastic or springy, which produces the same effects as an increase of its weight. The air which at one time raises water thirty-two feet in the tube, and quick- silver twenty-nine inches, will not at another raise the one to thirty feet, or the other to twenty-six inches. This makes, therefore, a very great difference in the weight we sus- tain ; and we are actually known, by compu- tation, to carry at one time four thousand pounds of air more than at another. The reason of this surprising difference in the weight of air, is either owing to its pres- sure from above, or to an increase of vapour floating in it. Its increased pressure is the consequence of its spring or elasticity, which cold and heat sensibly affect, and are con- tinually changing. This elasticity of the air is one of its most amazing properties ; and to which it should seem nothing can set bounds. A body of air that may be contained in a nut-shell, may easily, with heat, be dilated into a sphere of unknown dimensions. On the contrary, the air contained in a house, may be compressed into a cavity not larger than the eye of a needle. In short, no bounds can be set to its confinement or expansion ; at least, expe- riment has hitherto found its attempts in- definite. In every situation, it retains its elasticity ; and the more closely we compress it, the more strongly does it resist the pres- sure. If to the increasing the elasticity on one side by compression, we increase it on the other side by heat, the force of both soon becomes irresistible ; and a certain French philosopher" supposed, that air thus confined, and expanding, was sufficient for the explo- sion of a world. Many instruments have been formed to measure and determine these different pro- perties of the air; and which serve several useful purposes. The barometer serves to measure its weight; to tell us when it is hea- vier, and when lighter. It is composed of a glass tube or pipe, of about thirty inches in length, closed up at one end : this tube is then filled with quicksilver; this done, the maker, clapping his finger upon the open end, inverts the tube, and plunges the open end. finger and all, into a bason of quicksilver, and then takes his finger away : now the quicksilver in the tube will, by its own weight, endeavour to descend into that in the bason; but the external air, pressing on the surface of the quicksilver in the bason with- out, and no air being in the tube at top, the quicksilver will continue in the tube, be- ing pressed up, as was said, by the air, on the surface of the bason below. The height at which it is known to stand in the tube, is usually about twenty-nine inches, when the air is heavy; but not above twenty-six, when the air is very light. Thus, by this instru- ment we can, with some exactness, determine the weight of the air; and, of consequence, tell before-hand the changes of the weather. Before fine dry weather, the air is charged with a variety of vapours, which float in it unseen, and render it extremely heavy, so that it presses up the quicksilver ; or, in other words, the barometer rises. In moist, rainy weather, the vapours are washed down, or there is not heat sufficient for them to rise, so that the air is then sensibly lighter, and presses up the quicksilver with less force ; or, in other words, the barometer is seen to fall. Our constitutions seem also to corres^ pond with the changes of the weather-glass ; they are braced, strong, and vigorous, with a Monsieur Amontous. Or) A HISTORY OF a large body of air upon them ; they are lan- guid, relaxed, and feeble, when the air is light, and refuses to give our fibres their pro- per tone. But although the barometer thus measures the weight of the air with exactness enough for the general purposes of life, yet it is often affected with a thousand irregularities, that no exactness in the instrument can remedy, nor no theory account for. When high winds blow, the quicksilver generally is low ; it ri- ses higher in cold weather than in warm ; and is usually higher at morning and evening than at mid-day : it generally descends low- er after rain than it was before it. There are also frequent changes in the air, without any sensible alteration in the barometer. As the barometer is thus used in predict- ing the changes of the weather, so it is also serviceable in measuring the heights of moun- tains, which mathematicians cannot so readi- ly do : for as, the higher we ascend from the surface of the earth, the air becomes lighter, so the quicksilver in the barometer will de- scend in proportion. It is found to sink at the rate of the tenth part of an inch for every ninety feet we ascend ; so that in going up a moun- tain, if I find the quicksilver fallen an inch, I conclude that I am got upon an ascent of near nine hundred feet high. In this there has been found some variation ; into a detail of which, it is not the business of a natural historian to enter. In order to determine the elasticity of air, the wind-gun has been invented, which is an instrument variously made ; but in all upon the principle of compressing a large quanti- ty of air into a tube, in which there is an ivo- ry ball, and then giving the compressed elas- tic air free power to act, and drive the ball as directed. The ball thus driven, will pierce a thick board ; and will be as fatal, at small distances, as if driven with gunpowder. I do not know whether ever th" force of this instrument has been assisted by means of heat ; certain I am, that this, which could be very easily contrived by means of phospho- rus, or any other hot substance applied to the barrel, would give such a force as I doubt whether gunpowder itself could produce. The air-pump is an instrument contrived to exhaust the air from round a vessel adapt- ed to that purpose, called a receiver. This method of exhausting, is contrived in the simple instrument, by a piston, like that of a syringe, going down into the vessel, and thus pushing out its air ; which, by means of a valve, is prevented from returning into the vessel again. But this, like all other compli- cated instruments, will be better understood by a minute inspection, than an hour's de- scription : it may suffice here to observe, that by depriving animals, and other substances, of all air, it shows us what the benefits and effects of air are in sustaining life, or promo- ting vegetation. The digester is an instrument of still more extraordinary effects than any of the former; and sufficiently discovers the amazing force of air, when its elasticity is augmented by fire. A common tea-kettle, if the spout were closed up, and the lid put firmly down, would serve to become a digester, if strong enough. But the instrument used for this purpose is a strong metal pot, with a lid to screw close on, so that, when down, no air can get in or return : into this pot meat and bones are put, with a small quantity of water, and then the lid screwed close ; a lighted lamp is put un- derneath, and, what is very extraordinary, (yet equally true,) in six or eight minutes the whole mass, bones and all, are dissolved into a jelly; so great is the force and elasticity of the air contained within, struggling to escape, and breaking in pieces all the substances with which it is mixed. Care, however, must be taken not to heat this instrument too vio- lently ; for then the inclosed air would be- come irresistible, and burst the whole, with perhaps a fatal explosion. There are numberless other useful instru- ments made to depend on the weight, the elasticity, or the fluidity, of the air, which do not come within the plan of the present work; the design of which is not to give an account of the inventions that have been made for determining the nature and proper- ties of air, but a mere narrative of its effects. The description of the pump, the forcing- pump, the fire-engine, the steam-engine, the syphon, and many others, belong not to the naturalist, but the experimental pnilosopher: the one gives a history of Nature, as he finds she presents herself to him ; and he draws THE EARTH. 91 the obvious picture : the other pursues her with close investigation, tortures her by ex- periment to give up her Secrets, and mea- sures her latent qualities with laborious pre- cision. Much more, therefore, might be said of the mechanical effects of air, and of the conjectures that have been made respecting the form of its parts ; how some have suppo- sed them to resemble little hoops coiled up a spring; others, like fleeces of wool; in others, that the parts are endued with a re- pulsive quality, by which, when squeezed together, they endeavour to fly off, and re- cede from each other. We might have given the disputes relative to the height to which this body of air extends above us, and con- cerning which there is no agreement. We might have inquired how much of the air we breathe is .elementary,, and not reducible to any other substance ; and of what density it would become, if it were supposed to be con- tinued down to the centre of the earth. At that place we might, with the help of figures, and a bold imagination, have shown it twenty thousand times heavier than its bulk of gold. We might also prove it millions of times purer than upon earth, when raised to the surface of the atmosphere. But these specu- lations do not belong to natural history ; and they have hitherto produced no great advan- tages in that branch of science to which they more properly appertain. CHAPTER XIX. AN ESSAY TOWARDS A NATURAL HISTORY OF THE AIR. A LATE eminent philosopher has consi- dered our atmosphere as one large chymical vessel, in which an infinite number of various operations are constantly performing. In it all the bodies of the earth are continually sending up a part of their substance by evaporation, to mix in this great alembic, and to float a while in common. Here minerals, from their lowest depths, ascend in noxious, or in warm vapours, to make a part of the general mass ; seas, rivers, and subterranean springs, furnish their copious supplies ; plants receive and return their share ; and animals, that by living upon, consume this generalstore, are found to give it back in greater quanti- ties when they die." The air, therefore, that we breathe, and upon which we subsist, bears very little resemblance to that pure elementary body which was described in the last chapter; and which is rather a sub- stance that may be conceived, than experi- enced to exist. Air, such as we find it, is one of the most compounded bodies in all nature. Water may be reduced to a fluid every way resembling air, by heat ; which, a Boyle, vol. ii. p. 593. wo. 9 & 10. by cold, becomes water again. Every thing we see gives off its parts to the air, and has a little floating atmosphere of its own round it. The rose is encompassed with a sphere of its own odorous particles; while the night- shade infects the air with a scent of a more ungrateful nature. The perfume of musk flies off in such abundance, that the quantity remaining becomes sensibly lighter by the loss. A thousand substances that escape all our senses we know to be there ; the power- ful emanations of the load-stone, the effluvia of electricity, the rays of light, and the insi- nuations of fire. Such are the various substan- ces through which we move, and which we are constantly taking in at every pore, and returning again with imperceptible dis- charge ! This great solution, or mixture of all earth- ly bodies, is continually operating upon it- self; which, perhaps, may be the cause of its unceasing motion: but it operates still more visibly upon such grosser substances as are exposed to its influence; for scarcely any substance is found capable of resisting the corrodingqualities of the air. The air, say the chymists, is a chaos furnished with all kinds Y 92 A HISTORY OF of salts and menstruums ; and, therefore, it is capable of dissolving all kinds of bodies. It is well known, that copper and iron are quickly covered, and eaten with rust; and that, in the climates near the equator, no art can keep them clean. In those dreary coun- tries, the instruments, knives and keys, that are kept in the pocket, are nevertheless quickly incrusted ; and the great guns, with every precaution, after some years, become useless. Stones, as being less hard, may be readily supposed to be more easily soluble. The marble of which the noble monuments of Italian antiquity are composed, although in one of the finest climates in the world, show the impressions which have been made upon them by the air. In many places they seem worm-eaten by time; and, in others, they appear crumbling into dust. Gold alone seems to be exempted from this general state of dissolution ; it is never found to contract rust, though exposed never so long : the rea- son of this seems to be, that sea-salt, which is the only menstruum capable of acting up- on, and dissolving gold, is but very little mix- ed with the air ; for salt being a very fixed body, and not apt to volatilize, and rise with heat, there is but a small proportion of it in the atmosphere. In the elaboratories, and shops, however, where salt is much used, and the air is impregnated with it, gold is found to rust as well as other metals. Bodies of a softer nature are obviously de- stroyed by the air.* Mr. Boyle says, that silks brought to Jamaica, will, if there expo- sed to the air, rot, even while they preserve their colour ; but if kept therefrom, they both retain their strength and gloss. The same happens in Brazil, where their clothes, which are black, soon turn of an iron colour; though, in the shops, they preserve their proper hue. b In these tropical climates also, such are the putrescent qualities of the air, that white sugar will sometimes be full of maggots. Drugs and plaisters lose their vir- tue, and become verminous. In some places they are obliged to expose their sweetmeats by day in the sun, otherwise the night air would quickly cause them to putrefy. On the contrary, in the cold arctic regions, ani- a Button, vol. iii. p. 62. mal substances, during their winter, are ne- ver known to putrefy ; and meat may be kept for months without any salt whatsoever. This experiment happily succeeded with the eight Englishmen that were accidentally left upon the inhospitable coasts of Greenland, at a place where seven Dutchmen had perished but a few years before ; for killing some rein- deer for their subsistence, and having no salt to preserve the flesh, to their great surprise they soon found it did not want any, as it re- mained sweet during their eight months con- tinuance upon that shore. These powers, with which air is endued over unorganized substances, are exerted in a still stronger manner over plants, animals of an inferior nature, and, lastly, over man himself. Most of the beauty, and the luxuri- ance of vegetation, is well known to be de- rived from the benign influence of the air; and every plant seems to have its favourite climate, not less than its proper soil. The lower ranks of animals, also, seem formed for their respective climates, in which only they can live. Man alone seems the child of every climate, and capable of existing in all. How- ever, this peculiar privilege does not exempt him from the influences of the air; he is as much subject to its malignity as the meanest insect or vegetable. With regard to plants, air is so absolutely necessary for their life and preservation, that they will not vegetate in an exhausted re- ceiver. All plants have within them a quan- tity of air, which supports and agitates their juices. They are continually imbibing fresh nutriment from the air, to increase this store, and to supply the wants which they sustain from evaporation. When, therefore, the ex- ternal air is drawn from them, they are no longer able to subsist. Even that quantity of air which they before were possessed of, escapes through their pores, into the ex- hausted receiver; and as this continues to be pumped away, they become languid, grow flaccid, and die. However, the plant or flow- er thus ceasing to vegetate, is kept, by being secured from the external air, a much longer time sweet than it would have continued, had it been openly exposed. b Buffon, vol. iii. p. 68, THE EARTH. 93 That air which is so necessary to the life of vegetables, is still more so to that of ani- mals ; there are none found, how seemingly torpid soever, that do not require their need- ful supply. Fishes themselves will not live in water from whence the air is exhausted ; and it is generally supposed that they die in frozen ponds, from the want of this necessary to animal existence. Many have been the animals that idle curiosity has tortured in the prison of a receiver, merely to observe the manner of their dying. We shall, from a thousand instances, produce that of the viper, as it is known to be one of the most vivacious reptiles in the world ; and as we shall feel but little compassion for its tortures. Mr. Boyle took a new-caught viper, and shutting it up into a small receiver, began to pump away the air." " At first, upon the air's being drawn away, it began to swell ; some time af- ter he had done pumping, it began to gape, and open its jaws ; being thus compelled to open its jaws, it once more resumed its for- mer lankness ; it then began to move up and down within, as if to seek for air, and after a while foamed a little, leaving the foam stick- ing to the inside of the glass ; soon after, the body and neck grew prodigiously tumid, and a blister appeared upon its back; an hour and a half after the receiver was exhausted, the distended viper moved, and gave manifest signs of life ; the jaws remained quite distend- ed ; as it were from beneath the epiglottis, came the black tongue, and reached beyond it; but the animal seemed, by its posture, not to have any life ; the mouth also was grown blackish within ; and in this situation it continued for twenty-three hours. But upon the air's being re-admitted, the viper's mouth was presently closed, and soon after opened again ; and for some time those motions con- tinued, which argued the remains of life." Such is the fate of the most insignificant or minute reptile that can be thus included. Mites, fleas, and even the little eels that are found swimming in vinegar, die for want of air. Not only these, but the eggs of these ani- mals, will not produce in vacuo, but require air to bring them to perfection. As in this manner air is necessary to their Boyle'* Physico-Mechan. Exper. passim. subsistence, so also it must be of a proper kind, and not impregnated with foreign mix- tures. That factitious air which is pumped from plants or fluids, is generally, in a short time, fatal to them. Mr. Boyle has given us many experiments to this purpose. After having shown that all vegetable, and most mineral substances, properly prepared, may afford air, by being placed in an exhausted receiver, and this in such quantities, that some have thought it a new substance, made by the alteration which the mineral or plant has undergone by the texture of its parts being loosened in the operation having shown, I say, that this air may be drawn in great quantities from vegetable, animal, or mineral substances, such as apples, cherries, amber burnt, or hartshorn b he included a frog in artificial air, produced from paste ; in seven minutes space it suffered convulsions v and at last lay still, and being taken out, re- covered no motion at all, but was dead. A bird, inclosed in artificial air, from raisins, died in a quarter of a minute, and never stir- red more. A snail was put into the re- ceiver, with air of paste ; in four minutes it ceased to move, and was dead, although it had survived in vacuo for several hours : so that factitious air proved a greater enemy to ani- mals than even a vacuum itself. Air also may be impregnated with fumes that are instantly fatal to animals. The fumes of hot iron, copper, or any other heated metal, blown into the place where an animal is confined, instantly destroy it. We have al- ready mentioned the vapours in the grotto Del Cane suffocating a dog. The ancients even supposed, that these animals, as they al- ways ran with their noses to the gr.ound, were the first that felt any infection. In short, it should seem that the predominance of any one vapour, from any body, how wholesome soever in itself, becomes infectious ; and that we owe the salubrity of the air to the variety of its mixture. But there is no animal whose frame is more sensibly affected by the changes of the air than man. It is true, he can endure a greater variety of climates than the lower orders generally are able to do; but it is . b Boyle's Physico-Mechan, vol. ii. p. 598. Y* 94 A HISTORY OF rather by the means which he has discovered pf obviating their effects, than by the ap- parent strength of his constitution. Most other animals can bear cold or hunger better, endure greater fatigues in proportion, and are satisfied with shorter repose. The varia- tions of the climate, therefore, would pro- bably affect them the less, if they had the same means or skill in providing against the severities of the change. However this be, the body of man is an instrument much more nicely sensible of the variations of the air, than any of those which his own art has pro- duced ; for his frame alone seems to unite all their properties, being invigorated by the weight of the air, relaxed by its moisture, enfeebled by its heat, and stiffened by its frigidity. But it is chiefly by the predominance of some peculiar vapour, that the air becomes unfit for human support. It is often found, by dreadful experience, to enter into the constitution, to mix with its juices, and to putrefy the whole mass of blood. The ner- vous system is not less affected by its opera- tions; palsies and vertigoes are caused by its damps ; and a still more fatal train of dis- tempers by its exhalations. In order that the air should be wholesome, it is necessary, as we have seen, that it should not be of one kind, but the compound of several sub- stances; and the more various the compo- sition, to all appearance the more salubrious. A man, therefore, who continues in one place, is not so likely to enjoy this wholesome va- riety, as he who changes his situation ; and, if I may so express it, instead of waiting for a renovation of air, walks forward to meet its arrival. This mere motion, independent even of the benefits of exercise, becomes wholesome, by thus supplying a great variety of that healthful fluid by which we are sus- tained. A thousand accidents are found to increase these bodies of vapour, that make one place more or less wholesome than another. Heat may raise them in too great quantities ; and cold may stagnate them. Minerals may give off tHeir effluvia in such proportion as to keep away all other kind of air; vegetables may render the air unwholesome by their supply ; and animal putrefaction seems to furnish a quantity of vapour, at least as noxious as any of the former. All these united, generally make up the mass of respi- ration, and are, when mixed together, harm- less ; but any one of them, for a long time singly predominant, becomes at length fa- tal. The effects of heat in producing a noxious quality in the air, are well known. Those torrid regions under the Line are always un- wholesome. At Senegal, I am told, the na- tives consider forty as a very advanced time of life, and generally die of old age at fifty. At Carthagena," in America, where the heat of the hottest day ever known in Europe is continual, where, during their winter season, thesedreadful heats are united with a continual succession of thunder, rain, and tempests, arising from their intenseness, the wan and li- vid complexions of the inhabitants might make strangers suspect that they were just recover- ed from some dreadful distemper; the ac- tions of the natives are conformable to their colour; in all their motions there is some- what relaxed and languid ; the heat of the climate even affects their speech, which is soft and slow, and their words generally broken. Travellers from Europe retain their strength and ruddy colour in that climate, possibly for three or four months ; but after- wards suffer such decays in both, that they are no longer to be distinguished from the inhabitants by their complexion. However, this languid and spiritless existence is fre- quently drawled on sometimes even to eighty. Young persons are generally most affected by the heat of climate, which spares the more aged ; but all, upon their arrival on the coasts, are subject to the same train of fatal disorders. Few nations have experienced the mortality of these coasts, so much as our own ; in our unsuccessful attack upon Car- thagena, more than three parts of our army were destroyed by the climate alone ; and those that returned from that fatal expedition, found their former vigour irretriev;>l ty gone. In our more fortunate expedition, which gave us the Havannah, we had little reason to boast of our success; instead of a third, not a fifth part of the army were left survivors of Ullo, vol. i. p. 42. THE EARTH. 95 their victory, the climate being an enemy that even heroes cannot conquer. The distempers that thus proceed from the cruel malignity of those climates are many ; that, for instance, called the Chapo- tonadas, carries off' a multitude of people; and extremely thins the crews of European ships, whom gain tempts into those inhos- pitable regions. The nature of this distem- per is but little known, being caused in some persons by cold, in others by indigestion. But its effects are far from being obscure ; it is generally fatal in three or four days: upon its seizing the patient, it brings on what is there called the black vomit, which is the sad symptom after which none are ever found to recover. Some, when the vomit attacks them, are seized with a de- lirium, that, were they not tied down, they would tear themselves to pieces, and thus expire in the midst of this furious paroxysm. This disorder, in milder climates, takes the name of the bilious fever, and is attended with milder symptoms, but very dangerous in all. There are many other disorders incident to the human body, that seem the offspring of heat ; but to mention no other, that very lassitude which prevails in all the tropical climates, may be considered as a disease. The inhabitants of India," says a modern phi- losopher, sustain an unceasing languor, from the heats of their climate; and are torpid in the midst of profusion. For this reason, the great Disposer of Nature has clothed their country with trees of an amazing height, whose shade might defend them from the beams of the sun ; and whose continual fresh- ness might, in some measure, temperate their fierceness. From these shades, therefore, the air receives refreshing moisture, and ani- mals a cooling protection. The whole race ef savage animals retire, in the midst of the day, to the very centre of the forests, not so much to avoid their enemy man, as to find a defence against the raging heats of the sea- son. This advantage, which arises from shades in torrid climates, may probably af- ford a solution for that extraordinary circum- stance related by Boyle, which he imputes to Lirmaei Amceuitates, vol. v. p. 444. a different cause. In the island of Ternate, belonging to the Dutch, a place that had been long celebrated for its beauty and healthful- ness, the clove-trees grew in such plenty, that they in some measure lessened their own value : for this reason, the Dutch re solved to cut down the forests, and thus to raise the price of the commodity; but they had soon reason to repent of their avarice ; for such a change ensued, by cutting down the trees, that the whole island, from being healthy and delightful, having lost its charm- ing shades, became extremely sickly, and has actually continued so to this day. Boer- haave considered heat so prejudicial to health, that he was never seen to go near a fire. An opposite set of calamities are the con- sequence, in climates where the air is con- densed by cold. In such places, all that train of distempers which are known to arise from obstructed perspiration, are very com- mon ; b eruptions, boils, scurvy, and a loath- some leprosy, that covers the whole body with a scurf, and white putrid ulcers. These disorders also are infectious ; and, while they thus banish the patient from society, they generally accompany him to the grave. The men of those climates seldom attain to the age of fifty ; but the women, who do not lead such laborious lives, are found to live longer. The antumnal complaints which attend a wet summer, indicate the dangers of a moist air. The long continuance of an east wind also, shows the prejudice of a dry one. Mineral exhalations, when copious, are every where known to be fatal ; and although we probably owe the increase and luxuriance of vegetation to a moderate degree of their warmth, yet the natives of those countries where there are mines in plenty, but too often experience the noxious effects of their vici- nity. Those trades also that deal in the pre- parations of metals of all kinds, are always unwholesome ; and the workmen, after some time, are generally seen to labour under palsies, and other nervous complaints. The vapours from some vegetable substances, are well known to be attended with dangerous effects. The shade of the machinel tree, in b Krantz's History of Greenland, vol. i. p. 235. A HISTORY OF America, is said to be fatal ; as was that of the juniper, if we may credit the ancients. Those who walk through fields of poppies, or in any manner prepare those flowers for making opium, are very sensibly affected with the drowsiness they occasion. A physician of Mr. Boyle's acquaintance, causing a large quantity of black hellebore to be pounded in a mortar, most of the persons who were in the room, and especially the person who pounded it, were purged by it, and some of them strongly. He also gathered a certain plant in Ireland, which the person who beat it in a mortar, and the physician who was standing near, were eo strongly affected by, that their hands and faces swelled to an enor- mous size, and continued tumid for a long time after. But neither mineral nor vegetable steams are so dangerous to the constitution, as those proceeding from animal substances, putrefying either by disease or death. The effluvia that come from diseased bodies, propagate that frightful catalogue of disorders which are called infectious. The parts which compose vegetable vapours, and mineral exhalations, seem gross and heavy, in comparison of these volatile vapours, that go to great distances, and have been described as spreading deso- lation over the whole earth. They fly every where ; penetrate every where ; and the va- pours that fly from a single disease, soon ren- der it epidemic. The plague is the first upon the list in this class of human calamities. From whence this scourge of man's presumption may have its beginning, is not well known ; but we well know that it is propagated by infection. What- ever be the general state of the atmosphere, we learn, from experience, that the noxious vapours, though but singly introduced at first, taint the air by degrees : every person in- fected, tends to add to the growing malignity; and, as the disorder becomes more general, the putrescence of the air becomes more noxious, so that the symptoms are aggravated by continuance. When it is said that the origin of this disorder is unknown, it implies, that the air seems to be but little employed in first producing it. There are some coun- tries, even in the midst of Africa, that we learn have never been infected with it ; but continue, for centuries, unmolested. On the contrary, there are others, that are generally visited once a year, as in Egypt, which, never- theless, seems peculiarly blessed with the serenity and temperature of its climate. In the former countries, which are of vast extent, and many of them very populous, every thing should seem to dispose the air to make the plague continual among them. The great heats of the climate, the unwholesomeness of the food, the sloth and dirt of the inhabi- tants, but, above all, the bloody battles which are continually fought among them, after which heaps of dead bodies are left unburied, and exposed to putrefaction. All these one might think would be apt to bring the plague among them ; and yet, nevertheless, we are assured, by Leo Africanus, that in Numidia the plague is not known once in a hundred years ; and that in Negroland, it is not known at all. This dreadful disorder, therefore, must have its rise, not from any previous dis- position of the air, but from some particular cause, beginning with one individual, and extending the malignity, by communication, till at last the air becomes actually tainted by the generality of the infection. The plague which spread itself over the whole world, in the year 1346, as we are told by Mezeray, was so contagious, that scarcely a village, or even a house, escaped being in- fected by it. Before it had reached Europe, it had been for two years travelling from the great kingdom of Cathay, where it began by a vapour most horridly fetid ; this broke out of the earth like a subterranean fire, and upon the first instant of its eruption, consumed and desolated above two hundred leagues of that country, even to the trees and stones. In that great plague which desolated the city of London, in the year 1665, a pious and learned schoolmaster of Mr. Boyle's acquain- tance, who ventured to stay in the city, and took upon him the humane office of visiting the sick and the dying, who had been de- serted by better physicians, averred, that being once called to a poor woman who had buried her children of the plague, he found the room where she lay so little that it scarcely could hold any more than the bed whereon she was stretched. However, in this wretched abode, beside her, in an open THE EARTH. 97 coffin, her husband lay, who had some time before died of the same disease ; and whom she, poor creature, soon followed. But what showed the peculiar malignity of the air, thus suffering from animal putrefaction, was, that the contagious steams had produced spots on the very wall of their wretched apartment : and Mr. Boyle's own study, which was con- tiguous to a pest-house, was also spotted in the same frightful manner. Happily for man- kind, this disorder, for more than a century, has not been known in our island ; and, for this last age, has abated much of its violence, even in those countries where it is most com- mon. Diseases, like empires, have their re- volutions ; and those which for a while were the scourge of mankind, sink unheard of, to give place to new ones, more dreadful, as being less understood. For this revolution in disorders, which has employed the speculation of many, Mr. Boyle accounts in the following manner: " Since," says he, " there want not causes in the bowels of the earth to make considerable changes amongst the materials that nature has plenti- fully treasured up in those magazines, md as those noxious steams are abundantly supplied to the surface, it may not seem improbable, that in this great variety some may be found capable of affecting the human frame in a particular manner, and thus of producing new diseases. The duration of these may be greater or less, according to the lastingness of those subterraneous causes that produced them. On which account, it need be no won- der that some diseases have but a short du- ration, and vanish not long after they appear; whilst others may continue longer, as having under ground more settled and durable cau- ses to maintain them." From the recital of this train of mischiefs produced by the air upon minerals, plants, animals, and man himself, a gloomy mind may be apt to dread this indulgent nurse of na- ture as a cruel and an inexorable stepmother : but it is far otherwise ; and, although we are sometimes injured, yet almost all the com- forts and blessings of life spring from its pro- pitious influence. It would be needless to observe, that it is absolutely necessary for a Keil, Robinson. the support of our lives ; for of this, every mo- ment's experience assures us. But how it. contributes to this support, is not so readily comprehended. All allow it to be a friend, to whose benefits we are constantly obliged : and yet, to this hour, philosophers are divi- ded as to the nature of the obligation. The dispute is, whether the air is only useful by its weight to force our juices into circulation ;" or, whether, by containing a peculiar spirit, it mixes with the blood in our vessels, and acts like a spur to their industry. 1 * Perhaps it may exert both these useful offices at the same time. Its weight may give the blood its progressive motion, through the larger vessels of the body ; and its admixture with it cause those contractions of all the vessels, which serve to force it still more strongly for- ward, through the minutest channels of the circulation. Be this as it may, it is well known, that that part of our blood which has just received the influx of the air in our bo- dies, is of a very different colour from that which has almost performed its circuit. It has been found, that the arterial blood, which has been immediately mixed with the air in the lungs, and, if I may so express it, is just beginning its journey through the body, is of a fine florid scarlet colour ; while, on the con- trary, the blood of the veins, that is returning from having performed its duty, is of a black- ish crimson hue. Whence this difference of colour should proceed, is not well under- stood ; we only know the fact, that this florid colour is communicated by the air; and we are well convinced, that this air has been ad- mitted into the blood for very useful purposes. Besides this vital principal in animals, the air also gives life and body to flame. A can- dle quickly goes out in at exhausted receiver; for having soon consumed the quantity of air, it then expires for want of a fresh supply. There has been a flame contrived that will burn under water ; but none has yet been found that will continue to burn without air. Gunpowder, which is the most catching and powerful fire we know, will not go oft in an exhausted receiver ; nay, if a train of gunpow- der be laid, so as that one part may be fired in the open air, yet the other part in vacuo b Whytt upon Vital and Involuntary Motions. 98 A HISTORY OF will remain untouched, and unconsumed. Wood also set on fire, immediately goes out, and its flame ceases, upon removing the air ; for something is then wanting to press the body of the fire against that of the fuel, and to prevent the too speedy diffusion of the flame. We frequently see cooks, and others, whose business it is to keep up strong fires, take proper precautions to exclude the beams of the sun from shining upon them, which effectually puts them out. This they are apt to ascribe to a wrong cause; namely, the operation of the light ; but the real fact is, that the warmth of the sun-beams lessens and dissipates the body of the air that goes to feed the flame ; and the fire, of consequence, lan- guishes for want of a necessary supply. The air, while it thus kindles fire into flame, is notwithstanding found to moderate the rays of light, to dissipate their violence, and to spread an uniform lustre over every object. Were the beams of the sun to dart directly upon us, without passing through this protecting medium, they would either burn us up at once, or blind us with their effulgence. But by going through the air, they are reflected, refracted, and turned from their direct course, a thousand different ways; and thus are more evenly diffused over the face of nature. Among the other necessary benefits the air is of to us, one of the principal is its con- veyance of sound. Even the vibrations of a bell, which have the loudest effect that we know of, cease to be heard, when under the receiver of an air-pump. Thus all the plea- sures we receive from conversation with each other, or from music, depend entirely upon the air. Odours likewise are diffused only by the means of air; without this fluid to swim in, they would for ever remain torpid in their respective substances; and the rose would affect us with as little sensations of pleasure, as the thorn on which it grew. Those who are willing to augment the catalogue of the benefits we receive from this element, assert also, that tastes them- selves would be insipid, were it not that the air presses their parts upon the nerves of the tongue and palate, so as to produce their grateful effects. Thus, continue they, upon the tops of high mountains, as on the Peak of Teneriffe, the most poignant bodies, as pepper, ginger, salt, and spice, have no sen- sible taste, for want of their particles being thus sent home to the sensory. But we owe the air sufficient obligations, not to be stu- dious of admitting this among the number : in fact, all substances have their taste, as well*' on the tops of mountains, as in the bottom of the valley ; and I have been one of many, who have ate a very savoury dinner on the Alps. It is sufficient, therefore, that we regard the air as the parent of health and vegetation ; as a kind dispenser of light and warmth ; and as the conveyer of sounds and odours. This is an element of which avarice will not de- prive us; and which power cannot monopo- lize. The treasures of the earth, the verdure of the fields, and even the refreshments of the stream, are too often seen going only to assist the luxuries of the great ; while the less for- tunate part of mankind stand humble spec- tators of their encroachments. But the air no limitations can bound, nor any land-marks restrain. In this benign element, all mankind can boast an equal possession ; and for this we all have equal obligations to Heaven. We consume a part of it, for our own sus- tenance, while we live; and, when we die, our putrefyingbodies give back the supply, which, during life, we had accumulated from the ge- neral mass. THE EARTH. 99' CHAPTER XX. OF WINDS, IRREGULAR AND REGULAR. WIND is a current of air. Experimental philosophers produce an artificial wind, by an instrument called an eolipile. This is nothing more than a hollow copper ball, with a long pipe ; a tea-kettle might be readily made into one, if it were entirely closed at the lid, and the spout left open ; through this spout it is to be filled with water, and then set upon the fire, by which means it produces a violent blast, like wind, which continues while there is any water remaining in the instrument. In this manner water is con- verted into a rushing air; which, if caught as it goes out, and left to cool, is again quick- ly converted into its former element. Besides this, as was mentioned in the former chapter, almost every substance contains some por- tions of air. Vegetables, or the bodies of animals left to putrefy, produce it in a very copious manner. But it is not only seen thus escaping from bodies, but it may be very easily made to enter into them. A quantity of air may be compressed into water, so as to be intimately blended with it. It finds a much easier admission into wine, or any fer- mented liquor; and an easier still, into spirits of wine. Some salts suck up the air in such quantities, that they are made sensibly hea- vier thereby, and often are melted by its moisture. In this manner, most bodies, being found either capable of receiving or affording it, we are not to be surprised at those streams of air that are continually fleeting round the globe. Minerals, vegetables, and animals, contribute to increase the current; and are sending ofF their constant supplies. These, as they are differently affected by cold or hoat, by mixture or putrefaction, all yield different quantities of air at different times ; and the loudest tempests, and most rapid whirlwinds, are formed from their united contributions. The sun is the principal instrument in rarefying the juices of plants, so as to give an escape to their imprisoned air ; it is also equally operative in promoting the putrefac- tion of animals. Mineral exhalations are more frequently raised by subterranean heat. The moon, the other planets, the seasons, are all combined in producing these effects in a smaller degree. Mountains give a direc- tion to the courses of the air. Fires carry a current of air along their body. Night and day alternately chill and warm the earth, and produce an alternate current of its vapours. These, and many other causes, may be as- signed for the variety and the activity of the winds, their continual change, and uncertain duration. With us on land, as the wind proceeds from so many causes, and meets such a variety of obstacles, there can be but little hopes of everbringing its motions to conform to theory; or of foretelling how it may blow a minute to come. The great Bacon, indeed, was of opinion, that by a close and regular history of the winds, continued for a number of ages together, and the particulars of each observa- tion reduced to general maxims, we might at last come to understand the variations of this capricious element; and that we could fore- tell the certainty of a wind, with as much ease as we now foretell the return of an eclipse. Indeed, his own beginnings in this arduous undertaking, seem to speak the pos- sibility of its success ; but, unhappily for man- kind, this investigation is the work of ages, and we want a Bacon to direct the process. To be able, therefore, with any plausibility, to account for the variations of the wind upon land, is not to be at present expected ; and to understand any thing of their nature, we must have recourse to those places where they are more permanent and steady. This uniformity and steadiness we are chiefly to expect upon the ocean. There, where there is no variety of substances to furnish the air with various and inconstant supplies ; where there are no mountains to direct the course of its current, but where all is extensively 100 A HISTORY OF uniform and even; in such a place, the wind arising from a simple cause, must have but one simple motion. In fact, we find it so. There are many parts of the world where the winds, that with us are so uncertain, pay their stated visits. In some places they are found to hlow one way by day, and another by night ; in others, for one half of the year, they go in a direction contrary to their former course: but, what is more extraordinary still, there are some places where the winds never change, but for ever blow the same way. This is particularly found to obtain between the tropics in the Atlantic and ^Ethiopic oceans ; as well as in the great Pacific sea. Few things can appear more extraordinary to a person who has never been out of our variable latitudes, than this steady wind, that for ever sits in the sail, sending the vessel forward ; and as effectually preventing its re- turn. He who has been taught to consider that nothing in the world is so variable as the winds, must certainly be surprised to find a place where there is nothing more uniform. With us their inconstancy has become a pro- verb ; with the natives of those distant cli- mates they may talk of a friend or a mistress as fixed arid unchangeable as the winds, and mean a compliment by the comparison. When our ships are once arrived into the proper latitudes of the great Pacific ocean, the ma- riner forgets the helm, and his skill becomes almost useless : neither storms nor tempests are known to deform the glassy bosom of that immense sheet of waters; a gentle breeze, that for ever blows in the same direction, rests upon the canvass, and speeds the na- vigator. In the space of six weeks, ships are thus known to cross an immense ocean, that takes more than so many months to return. Upon returning, the trade-wind, which has been propitious, is then avoided : the mari- ner is generally obliged to steer into the nor- thern latitudes, and to take the advantage of every casual wind that offers, to assist him into port. This wind, which blows with such constancy one way, is known to prevail riot only in the Pacific ocean, but also in the Atlantic, between the coasts of Guinea and Brazil ; and, likewise, in the vEthiopic ocean. This seems to be the great universal wind, blowing from the east to the west, that pre- vails in all the extensive oceans, where the land does not frequently break the general current. Were the whole surface of the globe an ocean, there would probably be but this one wind, for ever blowing from the east, and pursuing the motions of the sun west- ward. All the other winds seem subordinate to this ; and m.vny of them are made from the deviations of its current. To form, therefore, any conception relative to the variations of the wind in general, it is proper to begin with that which never varies. There have been many theories to explain this invariable motion of the winds ; among the rest, we cannot omit that of Dr. Lyster, for its strangeness. " The sea," says he, " in those latitudes, is generally covered over with green weeds, for a great extent ; and the air produced from the vegetable perspiration of these, produces the trade-wind." The theory ofCartesius was not quite so absurd. He al- leged, that the earth went round faster than its atmosphere at the equator ; so that its mo- tion, from west to east, gave the atmosphere an imaginary one from east to west ; and thus an east wind was eternally seen to prevail. Rejecting those arbitrary opinions, conceived without force, and asserted without proof, Dr. Halley has given one more plausible; which seems to be the reigning system of the day. To conceive his opinion clearly, let us for a moment suppose the whole surface of the earth to be an ocean, and the air encompas- sing it on every side, without motion. Now it is evident, that that part of the air which lies directly under the beams of the sun, will be rarefied ; and if the sun remained for ever in the same place, there would be a great vacuity in the air, if I may so express it, be- neath the place where the sun stood. The sun moving forward from east to west, this va- cuity will follow too, and still be made under it. But while it goes on to make new vacui- ties, the air will rush in to fill up those the sun has already made ; in other words, as it is still travelling forward, the air will continually be rushing in behind, and pursue its motions from east to west. In this manner the air is put into motion by day; and by night the parts continue to impel each other, till the next re- turn of the sun, that gives a new force to the circulation. THE EARTH. 101 In this manner is explained the constant east wind that is found blowing round the globe, near the equator. But it is also known, that as we recede from the equator on either side, we come into a trade-wind, that con- tinually blows from the poles, from the north on one side, or the south on the other, both directing towards the equator. This also pro- ceeds from a similar cause with the former; for the air being more rarefied in those places over which the sun more directly darts its rays, the currents will come both from the north and the south, to fill up the interme- diate vacuity. These two motions, namely, the general one from east to west, and the more parti- cular one from both the poles, will account for all the phaenomena of trade-winds; which, if the whole surface of the globe were sea, would undoubtedly be constant, and for ever continue to blow in one direction. But there are a thousand circumstances to break these air-currents into smaller ones ; to drive them back against their general course ; to raise or depress them ; to condense them into storms; or to whirl them in eddies. In con- sequence of this, regard must be often had to the nature of the soil, the position of the high mountains, the course of the rivers, and even to the luxuriance of vegetation. : If a country, lying directly under the sun, be very flat and sandy, and if the land be low and extensive, the heats occasioned by the re- flection of the sun-beams, produces a very great rarefaction of the air. The deserts of Africa, which are conformable to this descrip- tion, are scarcely ever fanned by a breath of wind by day; but the burning sun is con- tinually seen blazing in intolerable splendour above them. For this reason, all along the coasts of Guinea, the wind is always per- ceived blowing in upon land, in order to fill up the vacuity caused by the sun's operation. In those shores, therefore, the wind blows in a contrary direction to that of its general current; and is constantly found setting in from the west. From the same cause it happens, that those constant calms, attended with deluges of rain, are found in the same part of the ocean. For this tract being placed in the middle, be- tween the westerly winds blowing on the coast of Guinea, and the easterly trade-winds that move at some distance from shore, in a contrary direction, the tendency of that part of the air that lies between these two oppo- site currents, is indifferent to either, and so rests between both in torpid serenity ; and the weight of the incumbent atmosphere, being diminished by the continual contrary winds blowing from hence, it is unable to keep the vapours suspended that are copi- ously borne thither ; so that they fall in con- tinual ruins. But it is not to be supposed, that any theory can account for all the phaenomena of even those winds that are known to be most regular. Instead of a complete system of the trade-winds, we must rather be content with an imperfect history. These," as was said, being the result of a combination of effects, assume as great a variety as the causes pro- ducing them are various. Besides the great general wind above men- tioned, in those parts of the Atlantic that lie under the temperate zone, a north wind pre- vails constantly during the months of Octo- ber, November, December, and January. These, therefore, are the most favourable months for embarking for the East Indies, in order to take the benefit of these winds, for crossing the Line: and it has been often found, by experience, that those who had set sail five months before, were not in the least far- ther advanced in their voyage, than those who waited for the favourable wind. During the winter of Nova Zembla, and the other arctic countries, a north wind reigns almost continually. In the Cape de Verde islands, a south wind prevails during the month of July. At the Cape of Good Hope, a north- west wind blows during the month of Sep- tember. There are also regular winds, pro- duced by various causes, upon land. The ancient Greeks were the first who observed a constant breeze, produced by the melting of the snows, in some high neighbouring countries. This was perceived in Greece, Thrace, Macedonia, and the jEgean sea. The same kind of winds are now remarked in the kingdom of Congo, and the most south- ern parts of Africa. The flux and reflux of Buftbn, vol. ii. p. 230. 102 A HISTORY OF the sea also produces some regular winds, that serve the purposes of trade ; and, in general, it may be observed, that wherever there is a strong current of water, there is a current of air that seems to attend it. Besides these winds that are Ibund to blow in one direction, there are, as was said be- fore, others that blow for certain months of the year, one way, and the rest of the year the contrary way : these are called the mon- soons, from a famous pilot of that name, who first used them in navigation with success." In all that part of the ocean that lies between Africa and India, the east winds begin at the month of January, and continue till about the commencement of June. In the month of August or September, the contrary direc- tion takes place ; and the west winds pre- vail for three or four months. The interval between these winds, that is to say, from the end of June to the beginning of August, there is no fixed wind , but the sea is usually tossed by violent tempests, proceeding from the north. These winds are always subject to their greatest variations as they approach the land ; so that, on one side of the great peninsula of India, the coasts are, for near half the year, harassed by violent hurricanes, and northern tempests ; while, on the oppo- site side, and all along the coasts of Coro- mandel, these dreadful tempests are wholly unknown. At Java and Ceylon, a west wind begins to reign in the month of September; but, at fifteen degrees of south latitude, this wind is found to be lost, and the great ge- neral trade-wind from the east is perceived to prevail. On the contrary, at Cochin, in China, the west wind begins at March; so that these monsoons prevail, at different seasons, throughout the Indies. So that the mariner takes one part of the year to go from Java to the Moluccas ; another from Cochin to Molucca: another from Molucca to China; and still another to direct him from China to Japan. There are winds also that may be con- sidered as peculiar to certain coasts; for example, the south wind is almost constant upon the coasts of Chili and Peru ; western winds almost constantly prevail on the coast * Varenii Geographia Generalis, cap. 20. of Terra Magellanica ; and in the environs of the Straits Le Maire. On the coasts of Malabar, north and north-west winds prevail continually; alorg the coast of Guinea, the north-west wind is also very frequent ; and, at a distance from the coasts, the north-east is always found prevailing. From the begin- ning of November to the end of December, a west wind prevails on the coasts of Japan $ and, during the whole winter, no ships can leave the port of Cochin, on account of the impetuosity of the winds that set upon the coast. These blow with such vehemence, that the ports are entirely choked up with sand, and even boats are not able to enter. However, the east winds that prevail for the other half of the year, clear the mouths of their harbours from the accumulations of the preceding winter, and set the confined ships at liberty. At the Straits of Babelmandel there is a south wind that periodically re- turns, and which is always followed by a north-east. Besides winds thus peculiar to certain coasts, there are others found to prevail on all the coasts, in warm climates, which, during one part of the day, blow from the shore, and, during another part of it, blow from the sea. The sea-breeze, in those countries, as Dampier observes, commonly rises in the morning, about nine, proceeding slowly, in a tine small black curl, upon the surface of the water, and making its way to refresh the shore. It is gentle at first, but increases gra- dually till twelve, then insensibly sinks away, and is totally hushed at five. Upon its ceas- ing, the land-breeze begins to take its turn, which increases till twelve at night, and is succeeded, in the morning, by the sea-breeze again. Without all doubt, nothing could have been more fortunate for the inhabitants of the warm countries, where those breezes blow, than this alternate refreshment, which they feel at those seasons when it is most wanted. The heat, on some coasts, would be insupportable, were it not for such a sup- ply of air, when the sun has rarefied all that which lay more immediately under the coast. The sea-breeze temperates the heat of the sun by day ; and the land-breeze corrects the malignity of the dews and vapours by night. Where these breezes, therefore, pre- THE EARTH 103 vail, (and they are very common,) the in- habitants enjoy a share of health and hap- piness, unknown to those that live much far- ther up the country, or such as live in similar j latitudes without this advantage. The cause | of these obviously seems to arise from the . rarefaction of the air by the sun, as their ! duration continues with its appearance, and I alters when it goes down. The sun, it is ob- served, equally diffusing his beams upon land and sea, the land, being a more solid body than the water, receives a greater quantity of heat, and reflects it more strongly. Being thus, therefore, heated to a greater degree than the waters, it, of consequence, drives the air from land out to sea: but, its influence being removed, the air returns to fill up the former vacuity. Such is the usual method of accounting for this phenomenon; but, un- r ortunately, these sea and land-breezes are visitants that come at all hours. On the coasts of Malabar," the land-breezes begin at midnight, and continue till noon; then the sea-breezes take their turn, and continue till midnight. While, again, at Congo, the land- breezes begin at five, and continue till nine the next day. But, if the cause of these be so inscrutable, that are, as we see, tolerably regular in their visitations, what shall we say to the winds of our own climate, that are continually shift- ing, and incapable of rest? Some general causes may be assigned, which nothing but particular experience can apply. And, in the first place, it may be observed, that clouds and heat, and, in short,whatever either increases the density or the elasticity of the air, in any one place, will produce a wind there : for the increased activity of the air thus pressing more powerfully on the parts of it that are adjacent, will drive them for- ward ; and thus go on, in a current, till the whole comes to an equality. In this manner, as a denser air produces a wind, on the one hand ; so will any accident, that contributes to lighten the air, produce it on the other : for, a lighter air may be con- sidered as a vacuity into which the neigh- bouring air will rush : and hence it happens, that when the barometer marks a peculiar Buffon, vol. ii. p. 252. lightness in the air, it is no wonder that it foretells a storm. The winds, upon large waters, are gene- rally more regular than those upon land. The wind at sea generally blows with an even steady gale; the wind, at land, puff's by inter- vals, increasing its strength, and remitting it, without any apparent cause. This, in a great measure, may be owing to the many moun tains, towers, or trees, that it meets in its way, all contributing either to turn it from its course, or interrupt its passage. The east wind blows more constantly than any other, arid for an obvious reason : all other winds are, in some measure, deviations from it, and partly may owe their origin thereto. It is generally, likewise, the most powerful, and for the same reason. There are often double currents of the air. While the wind blows one way, we frequent- ly see the clouds move another. This is ge- nerally the case before thunder; for it is well known that the thunder cloud always moves against the wind: the cause of this surprising appearance has hitherto remained a secret. From hence we may conclude, that weather- cocks only inform us of that current of the air, which is near the surface of the earth ; but are often erroneous with regard to the upper regions ; and, in fact, Derham has often found them erroneous. Winds are generally more powerful on elevated situations than on the plain, because their progress is interrupted by fewer ob- stacles. In proportion as we ascend the heights of a mountain, the violence of the weather seems to increase, until we have got above the region of storms, where all is usually calm and serene. Sometimes, how- ever, the storms rise even to the tops of the highest mountains; as we learn from those who have been on the Andes, and as we are convinced by the deep snows that crown even the highest. Winds blowing from the sea are generally moister, and more attended with rains, than those which blow over extensive tracts of land: for the sea gives off more vapours to the air, and these are rolled forward upon land, by the winds blowing from thence. b Foi b Derham's Physico-Theol. 104 A HISTORY OF this reason, our easterly winds that blow from the continent, are dry, compared with those that blow from the surface of the ocean, with which we are surrounded on every other quarter. In general the winds are more boisterous in spring and autumn than at other seasons : for that being the time of high tides, the sea may communicate a part of its motions to the winds. The sun and moon, also, which then have a greater effect upon the waters, may also have some influence upon the winds : for, there being a great body of air surrounding the globe, which, if condensed into water, would cover it to the depth of thirty-two feet, it is evident that the sun and moon will, to a proportionable degree, affect the atmosphere, and make a tide of air. This tide will be scarcely perceivable, indeed ; but, without doubt, it actually exists; and may contribute to increase the vernal and autumnal storms, which are then known to prevail. Upon narrowing the passage through which the air is driven, both the density and the swiftness of the wind is increased. For, as currents of water flow with greater force and rapidity by narrowing their channels ; so also will a current of air, driven through a con- tracted space, grow more violent and irresis- tible. Hence we find those dreadful storms that prevail in the defiles of mountains, where the wind, pushing from behind through a narrow channel, at once increases in speed and density, levelling, or tearing up, every obstacle that rises to obstruct its passage. Winds reflected from the sides of moun- tains and towers, are often found to be more forceful than those in direct progression. This we frequently perceive near lofty build- ings, such as churches or steeples, where winds are generally known to prevail, and that much more powerfully than at some distance. The air, in this case, by striking against the side of the building, acquires ad- ditional density, and, therefore, blows with more force. These differing degrees of density, which the air is found to possess, sufficiently show that the force of the winds do not depend upon their velocity alone ; so that those in- struments called anemometers, which are made to measure the velocity of the wind, will by ! no means give us certain information of the j force of the storm. In order to estimate this with exactness, we ought to know its density ; I which also these are not calculated to dis- : cover. For this reason we often see storms, ! with very powerful effects, that do not seem to I show any great speed; and, on the contrary, we j see these wind-measurers go round with great ! swiftness, when scarcely any damage has fol- i lowed from the storm. Such is the nature and the inconstancy of the irregular winds, with which we are best acquainted. But their effects are much more formidable in those climates near the tropics, where they are often found to break in upon the steady course of the trade-winds, and to mark their passage with destruction. With us the tempest is but rarely known, and its ravages are registered as an uncommon cala- mity ; but in the countries that lie between the tropics, and for a good space beyond them, its visits are frequent, and its effects are an- ticipated. In these regions the winds vary their terrors ; sometimes involving all things in a suffocating heat ; sometimes mixing all the elements of fire, air, earth, and water, to- gether ; sometimes, with a momentary swift- ness, passing over the face of the country, and destroying all things in their passage; and sometimes raising whole sandy deserts in one country, to deposite them upon some other. We have little reason, therefore, to envy these climates the luxuriance of their soil, or the brightness of their skies. Our own muddy atmosphere, that wraps us round in obscurity, though it fails to gild our prospects with sun- shine, or our groves with fruitage, neverthe- less answers the call of industry. They may boast of a plentiful, but precarious, harvest ; while, with us, the labourer toils in a certain expectation of a moderate, but a happy re- turn. In Egypt, a a kingdom so noted for its fer- tility and the brightness of its atmosphere, during summer, the south winds are so hot, that they almost stop respiration; besides which, they are charged with such quantities of sand, that they sometimes darken the air, as with a thick cloud. These sands are so fine, and driven with such violence, that they Buflfon, vol. ii. p. 258. THE EARTH. J05 penetrate every where, even into chests, be they shut never so closely. If these winds happen to continue for any length of time, they produce epidemic diseases, and are of- ten followed by a great mortality. It is also found to rain but very seldom in that country : however, the want of showers is richly com- pensated by the copiousness of their dews, which greatly tend to promote vegetation. In Persia, the winter begins in November, and continues till March. The cold at that time is intense enough to congeal the water ; and snow falls in abundance upon their moun- tains. During the months of March and April, winds arise, that blow with great force, and seem to usher in the heats of summer. These return again in autumn, with some vio- lence; without, however, producing any dreadful effects. But, during their summer, all along the coasts of the Persian Gulf, a very dangerous wind prevails, which the na- tives call the Sameyel, still more dreadful and burning than that of Egypt, and attended with instant and fatal effects. This terrible blast, which was, perhaps, the pestilence of the ancients, instantly kills all those that it involves in its passage. What its malignity consists in, none can tell, as none have ever survived its effects, to give information. It frequently, as I am told, assumes a visible form, and darts, in a kind of bluish vapour, along the surface of the country. The na- tives, not only of Persia, but of Arabia, talk of its effects with terror ; and their poets have not failed to heighten them with the assis- tance of imagination. They have described it as under the conduct of a minister of ven- geance, who governs its terrors, and raises, or depresses it, as he thinks proper. 3 These deadly winds are also known along the coasts of India, at Negapatam, Masulipatam, and Petapoli. But, luckily for mankind, the short- ness of their duration diminishes the injuries that might ensue from their malignity. The Cape of Good Hope, as well as many islands in the West-Indies, are famous for their hurricanes, and that extraordinary kind of cloud which is said to produce them. This cloud, which is the forerunner of an ap- proaching hurricane, appears, when first seen, Herbelot, Bibliotheque Oriental. like a small black spot, on the verge of the horizon ; and is called, by sailors, the bull's eye, from being seen so minute at a vast dis- tance. All this time a perfect calm reigns over the sea and land, while the cloud grows gradually broader as it approaches. At length, coming to the place where its fury is to fall, it invests the whole horizon with dark- ness. During all the time of its approach, an hollow murmur is heard in the cavities of the mountains ; and beasts and animals, sensible of its approach, are seen running over the fields, to seek for shelter. Nothing can be more terrible than its violence when it begins. The houses in those countries, which are made of timber, the better to resist its fury, bend to the blast like osiers, and again re- cover their rectitude. The sun, which but a moment before blazed with meridian splen- dour, is totally shut out; and a midnight darkness prevails, except that the air is in- cessantly illuminated with gleams of lightning, by which one can easily see to read. The rain falls, at the same time, in torrents ; and its descent has been resembled to what pours from the spouts of our houses after a violent shower. These hurricanes are not less offen- sive to the sense of smelling also, and never come without leaving the most noisome stench behind them. If the seamen also lay by their wet clothes, for twenty-four hours, they are all found swarming with little white rnag- S)ts, that were brought with the hurricane, ur first mariners, when they visited these regions, were ignorant of its effects, and the signs of its approach; their ships, therefore, were dashed to the bottom at the first onset ; and numberless were the wrecks which the hurricane occasioned. But, at present, being forewarned of its approach, they strip their masts of all their sails, and thus patiently abide its fury. These hurricanes are com- mon in all the tropical climates. On the coasts of Guinea they have frequently three or four in a day, that thus shut out the hea- vens for a liltle space ; and, when past, leave all again in former splendour. They chiefly prevail, on that coast, in the intervals of the trade winds ; the approach of which clears the air of its meteors, and gives these mortal showers that little degree of wholesomeness which they possess. They chiefly obtain 106 A HISTORY OF there during the months of April and May ; they are known at Loango from January to April; on the opposite coast of Africa, the hurricane season begins in May; and, in ge- neral, whenever a trade-wind begins to cease, these irregular tempests are found to exert their fury. All this is terrible : but there is a tempest, known in those climates, more formidable than any we have hitherto been describing, which is called, by the Spaniards, a Tornado. As the former was seen arriving from one part of the heavens, and making a line of destruc- tion ; so the winds in this seem to blow from every quarter, and settle upon one destined place, with such fury, that nothing can resist their vehemence. When they have all met in their central spot, then the whirlwind be- gins with circular rapidity. The sphere every moment widens, as it continues to turn, and catches every object that lies within its attrac- tion. This also, like the former, is preceded by a flattering calm; the air is every where hushed ; and the sea is as smooth as polished glass : however, as its effects are more dread- ful than those of the ordinary hurricane, the mariner tries all the power of his skill to avoid it; which, if he fails of doing, there is the greatest danger of his going to the bot- tom. All along the coasts of Guinea, begin- ning about two degrees north of the line, and so downward, lengthwise, for about a thou- sand miles, and as many broad, the ocean is unnavigable on account of these tornadoes. In this torrid region there reign unceasing tornadoes, or continual calms ; among which, whatever ship is so unhappy as to fall, is to- tally deprived of all power of escaping. In this dreadful repose of all the elements, the solitary vessel is obliged to continue, without a single breeze to assist the mariner's wishes, except those whirlwinds, which only serve to increase his calamity. At present, therefore, this part of the ocean is totally avoided ; and, although there may be much gold along the coasts of that part of Africa, to tempt avarice, yet there is something much more dreadful than the fabled dragon of antiquity, to guard the treasure. Asthe internal parts of that coun- try are totally unknown to travellers, from their burning sands and extensive deserts, so here we find a vast tract of ocean, lying oiF its shores, equally unvisited by the ma- riner. But of all these terrible tempests that de- form the face of Nature, and repress human presumption, the sandy tempests of Arabia and Africa are the most terrible, and strike the imagination most strongly. To conceive a proper idea of these, we are by no means to suppose them resembling those whirlwinds of dust that we sometimes see scattering in in our air, and sprinkling their contents upon our roads or meadows. The sand-storm of Africa exhibits a very different appearance. As the sand of which the whirlwind is com- posed is excessively fine, and almost resem- bles the parts of water, its motion entirely re- sembles that of a fluid ; and the whole plain seems to float onward, like a slow inundation. The body of sand thus rolling, is deep enough to bury nouses and palaces in its bosom : tra- vellers, who are crossing those extensive de- serts, perceive its approach at a distance ; and, in genera 1 have time to avoid it, or turn out of its way, as it generally extends but to a moderate breadth. However, when it is extremely rapid, or very extensive, as some- times is the case, no swiftness, no art, can avail; nothing then remains, but to meet death with fortitude, and submit to be buried alive with resignation. It is happy for us of Britain, that we have no such calamity to fear; for, from this, even some parts of Europe are not entirely free. We have an account given us, in the History of the French Academy, of a miserable town in France, that is constantly in danger of be- ing buried under a similar inundation; with which I will take leave to close this chapter. " In the neighbourhood of St. Paul de Leon, in Lower Brittany, there lies a tract of coun- try along the sea-side, which before the year 1666 was inhabited, but now lies deserted, by reason of the sands which cover it, to the height of twenty feet ; and which every year advance more and more inland, and gain ground continually. From the time men- tioned above, the sand has buried more than six leagues of the country inward : and it is now but half a league from the town of St. Paul ; so that, in all appearance, the inha- " Histoire de 1'Academie des Sciences, an. 1722. THE EARTH. 107 bitants must be obliged to abandon it en- tirely. In the country that has been overwhelm- ed, there are still to be seen the tops of some steeples peeping through the sand, and many chimneys that still remain above the sandy ocean. The inhabitants, however, had suffi- cient time to escape ; but being deprived of their little all, they had no other resource but begging for their subsistence. This ca- lamity chiefly owes its advancement to a north, or an east wind, raising the sand, which is extremely fine, in such great quantities, and with such velocity, that M. Deslandes, who gave the account, says, that while he was walking near the place, during a mode- rate breeze of wind, he was obliged, from time to time, to shake the sand from his clothes and his hat, on which it was lodged in great quantities, and made them too heavy to be easily borne. Still further, when the wind was violent, it drove the sand across a little arm of the sea, into the town of Roscoff, and covered the streets of that place two feet deep ; so that they have been obliged to carry it off in carts. It may also be ob- served, that there are several particles of iron mixed with the sand, which are readily affected by the loadstone. The part of the coast that furnishes these sands, is a tract of about four leagues in length ; and is upon a level with the sea at high-water. The shore lies in such a manner as to leave its sands subject only to the north and east winds, that bear them farther up the shore. It is easy to conceive how the same sand that has at one time been borne a short way inland, may, by some succeeding and stronger blast, be carried up much higher; and thus the whole may continue advancing forward, de- luging the plain, and totally destroying its fertility. At the same time, the sea, from whence this deluge of sand proceeds, may furnish it in inexhaustible quantities. This unhappy country, thus so overwhelmed in so singular a manner, may well justify what the ancients and the moderns have reported con- cerning those tempests of sand in Africa, that are said to destroy villages, and even armies in their bosom." CHAPTER XXI. OF METEORS, AND SUCH APPEARANCES AS RESULT FROM A COMBINATION OF THE ELEMENTS. IN proportion as the substances of nature are more compounded and combined, their appearances become more inexplicable and amazing. The properties of water have been very nearly ascertained. Many of the quali- ties of air, earth, and fire, have been disco- vered and estimated ; but when these come to be united by nature, they often produce a result which no artificial combinations can imitate: and we stand surprised, that although we are possessed of all those substances which nature makes use of, she shows her- self a much more various operator than the most .skilful chemist ever appeared to be. Every cloud that moves, and every shower that falls, serves to mortify the philosopher's pride, and to show him hidden qualities in air and water, that he finds it difficult to ex- plain. Dews, hail, snow, and thunder, are not less difficult for being more common. In- deed, when we reflect on the manner in which nature performs any one of these ope- rations, our wonder increases. To see water, which is heavier than air, rising in air, and then falling in a form so very different from that in which it rose ; to see the same fluid at one time descending in the form of hail, at another in that of snow ; to see two clouds, by dashing against each other, producing an electrical fire, which no watery composition that we know of can effect ; these, I say, serve sufficiently to excite our wonder; and still the more, in proportion as the objects are ever pressing on our curiosity. Much. 2 A 100 A HISTORY OF however, has been written concerning the manner in which nature operates in these productions ; as nothing is so ungrateful to mankind as hopeless ignorance. And first, with regard to the manner in which water evaporates, and rises to form clouds, much has been advanced, and many theories devised. All water," say some, has a quantity of air mixed with it ; and the heat of the sun darting down, disengages the par- ticles of this air from the grosser fluid ; the sun's rays being reflected back from the water, carry back with them those bubbles of air and water, which, being lighter than the condensed air, will ascend till they meet with a more rarefied air; and they will then stand suspended. Experience, however, proves nothing of all this. Particles of air or fire, are not thus known to ascend with a thin coat of water; and, in fact, we know that the little particles of steam are solid drops of water. But, besides this, water is known to evaporate more powerfully in the severest frost, than when the air is moderately warm. b Dr. Hamilton, therefore, of the uni- versity of Dublin, rejecting this theory, has endeavoured to establish another. According to him, as aqua-fortis is a menstruum that dis- solves iron, and keeps it mixed in the fluid ; as aqua-regia is a menstruum that dissolves gold ; or as water dissolves salts to a certain quantity, so air is a menstruum that corrodes and dissolves a certain quantity of water, and keeps it suspended above. But however in- genious this may be, it can hardly be admit- ted : as we know by Mariotte's experiment," that if water and air be inclosed together, in- stead of the air's acting as a menstruum upon the water, the water will act as a menstruum upon the air, and take it all up. We know also, that of two bodies, that which is most fluid and penetrating, is most likely to be the menstruum of the other; but water is more fluid and penetrating than air, and therefore the most likely of the two to be the menstruum. We know that all bodies are more speedily acted upon, the more their parts are brought into contact with the men- struum that dissolves them ; but water, in- a Spectacle de la Nature, vol. iii. b Memoires de 1' Academic des Sciences, an. 1705. closed with compressed air, is not the mdre diminished thereby.* 1 In short, we know that cold, which diminishes the force of other men- struuras, is often found to promote evapora- tion. In this variety of opinion and uncer- tainty of conjecture, I cannot avoid thinking that a theory of evaporation may be formed upon very simple and obvious principles, and embarrassed, as far as I can conceive, with very few objections. We know that a repelling power prevails in nature, not less than an attractive one. This repulsion prevails strongly between the body of fire and that of water. If I plunge the end of a red-hot bar of iron into a vessel of water, the fluid rises, and large drops of it fly up in all manner of directions, every part bubbling and steaming until the iron be cold. Why may we not ibr a moment compare the rays of the sun, darted directly upon the sur- face of the water, to so many bars of red-hot iron, each bar indeed infinitely small, but not the less powerful ? In this case, wher- ever a ray of fire darts, the water, from its re- pulsive quality, will be driven on all sides; and, of consequence, as in the case of the bar of iron, a part of it will rise. The parts thus rising, however, will be extreau-ly small ; as the ray that darts is extremely so. The assemblage of the rays darting upon the water is this manner, will cause it to rise in a light thin steam above the surface ; and as the parts of this steam are extremely minute, they will be lighter than air, and consequently float upon it. There is no need for supposing them bubbles of water filled with fire ; for any substance, even gold itself, will float on air, if its parts be made small enough ; or, in other words, if its surface be sufficiently in- creased. This water, thus disengaged from the general mass, will be still farther atten- uated and broken by the reflected rays, and consequently more adapted for ascending. From this plain account, every appearance in evaporation may be easily deduced. The quantity of heat increases evaporation, be- cause it raises a greater quantity of steam. The quantity of wind increases evaporation ; for, by waving the surface of the wateryjt thus c Mariotte, de la Nature de 1'Air, p. 97, 106. * See Boyle'* Works, vol. ii. p. 6l9. THE EARTH. 109 exposes a greater surface to the vaporating rays. A dry frost, in some measure, assists the quantity of evaporation ; as the quantity of rtys are found to be no way diminished th<> 'by. Moist weather alone prevents eva- poration; for the rays being absorbed, re- fracted, and broken, by the intervening mois- ture, before they arrive at the surface, cannot produce the effect; and the vapour will rise in a small proportion. Thus far we have accounted for the ascent of vapours; but to accountfor their fallingagain is attetided with rather more difficulty. We have already observed, that the particles of vapour, disengaged from the surface iof the water, will be broken and attenuated in their ascent, by the reflected, and even the direct rays, that happen to strike upon their minute surfaces. They will, therefore, continue to ascend, till they rise above the 'operation of the reflected rays, which reaches but to a certain height above the surface of the earth. Being arrived at tin's region, which is cold for want of reflected heat, they will be con- densed, and suspended in the form of clouds. Some vapours, that ascend to great heights, will be frozen into snow : others, that are con- densed lower down, will put on the appear- ance of a mist, which we find the clouds to be when we ascend among them, as they hang along the sides of a mountain. These clouds of snow and rain, being blown about by winds, are either entirely scattered and dispersed above, or they are still more condensed by ; motion, like a snow-ball, that grows more large and solid as it continues to roll. At last, therefore, they will become too weighty for the air which first raised them to sustain ; and they will descend with their excess of weight, either in snow or rain. But, as they will fall precipitately, when they begin to descend,the air, in some measure, will resist the falling: for, as the descending fluid gathers velocity in its precipitation, the air will increase its resistance to it, and the water will, therefore, be thus broken into rain ; as we see that wa- ter which falls from the tops of houses, though it begins in a spout, separates into drops before it has got to the bottom. Were it not for this happy interposition of the air, be- tween us and the water falling from a consi- derable height above us, a drop of rain might fall with dangerous force, and a hailstone might strike us with fatal rapidity. In this mariner, evaporation is produced by day ; hut when the sun goes down, a part of that vapour which his rays had excited, being no longer broken, and attenu ted by the reflecting rays, it will become heavier than the air, even before it has reached the clouds; and it will, therefore, fall back in dews, which differ only from rain in descend- ing before they have had time to condense into a visible form. Hail, the Cartesians say, is a frozen cloud, half melted, and frozen again in its descent. A hoar frost is but a frozen dew. Lightning we know to be an electrical flash, produced by the opposition of two clouds : and thun- der to be the sound proceeding from the same, continued by an echo reverberated among them. It would be to very little pur- pose to attempt explaining exactly how these wonders are effected ; we have as yet but little insight into the manner in which these meteors are found to operate upon each other; and, therefore, we must be contented with a detail rather of their effects than their causes. In our own gentle climate, where nature wears the mildest and kindest aspect, every meteor seems to befriend us. With us, rains fall in refreshing showers, to enliven our fields, and to paint the landscape with a more vivid beauty. Snows cover the earth, to preserve its tender vegetables from the inclemency of the departing winter. The dews descend with such an imperceptible fall as no way in- jures the constitution. Even thunder is sel- dom injurious ; and it is often wished lor by the husbandman, to clear the air, and to kill numberless insects that are noxious to vege- tation. Hail is the most injurious meteor that is known in our climate ; but it seldom visits us with violence, and then its fury is but transient. One of the most dreadful storms we hear of," was that of Hertfordshire, in the year 1697. It began by thunder and lightning, which continued for some hours, when sud- denly a black cloud came forward, against the wind, and marked its passage with de- Phil. Trans, vol. ii. p. 147. 2A 110 A HISTORY OF vastation. The hailstones which it poured down, being measured, were found to be many of them fourteen inches round, and, con- sequently, as large as a bowling-green ball. Wherever it came, every plantation fell be- fore it ; it tore up the ground, split great oaks, and other trees, without number ; the fields of rye were cut down, as if levelled with a scythe; wheat, oats, and barley, suffered the same damage. The inhabitants found but a precarious shelter, even in their houses, their tiles and windows being broke by the violence of the hailstones, which, by the force with which they came, seemed to have descended from a great height. The birds, in this uni- versal wreck, vainly tried to escape by flight ; pigeons, crows, rooks, and many more of the smaller and feebler kinds,were brought down. An unhappy young man, who had not time to take shelter, was killed; one of his eyes was struck out of his head, and Ins body was all over black with the bruises; another had just time to escape, but not without the most im- minent danger, his body being bruised all over. But what is most extraordinary, all this fell within the compass of a mile. Mezeray, in his history of France, tells us of a shower of hail much more terrible, which happened in the year 1510, when the French monarch invaded Italy. There was, for a time, a horrid darkness, thicker than that of midnight, which continued till the terrors of mankind were changed to still more terrible objects, by thunder and lightning breaking the gloom, and bringing on such a shower of hail, as no history of human calamities could equal. These hailstones were of a bluish colour, and some of them weighed not less than a hundred pounds. A noisome vapour of sulphur attended the storm. All the birds and beasts of the country were entirely de- stroyed. Numbers of the human race suffer- ed the same fate. But what is still more ex- traordinary, the fishes found no protection from their native element ; but were equal sufferers in the general calamity. These, however, are terrors that are seldom exerted in our mild cliimtes. They only serve to mark the page of history with won- der; and stand as admonitions to man- kind of the various stores of punishment in the hands of the Deity, which his power can treasure up, and his mercy can suspend. In the temperate zones, therefore, meteors I are rarely found thus terrible; but between the tropics, and near the poles, they assume very dreadful and various appearances. In those inclement regions, where cold and heat exert their chief power, meteors seem pecu- liarly to have fixed their residence. They are seen there in a thousand terrifying forms, astonishing to Europeans, yet disregarded by the natives, from their frequency. The won- ders of air, fire, and water, are there com- bined, to produce the most tremendous ef- fects ; and to sport with the labours and ap- prehensions of mankind. Lightnings, that flash without noise ; hurricanes, that tear up the earth ; clouds, that all at once pour down their contents, and produce an instant deluge; mock suns; northern lights, that illuminate half the hemisphere ; circular rainbows ; halos; fleeting balls of fire ; clouds, reflecting back the images of things on earth, like mir- rors ; and water-spouts, that burst from the sea, to join with the mists that hang imme- diately above them. These are but a part of the phenomena that are common in those countries ; and from many of which our own climate is, in a great measure, exempted. The meteors of the torrid zone are different from those that are found near the polar cir- cles ; and it may readily be supposed, that in those countries where the sun exerts the greatest force in raising vapours of all kinds, there should be the greatest quantity of me- teors. Upon the approach of the winter months, as they are called, under the Line, which usually begin about May, the sky, from a fiery brightness, begins to be overcast, and the whole horizon seems wrapt in a muddy cloud. Mists and vapours still continue to rise ; and the air, which so lately before was clear and elastic, now becomes humid, ob- scure, and stifling : the fogs become so thick, that the light of the sun seems, in a manner, excluded; nor would its presence be known, but for the intense and suffocating heat of its beams, which dart through the gloom, and, instead of dissipating, only serve to incr^"e the mist. After this preparation, there follcws r*,j al most continual succession of thunder, rain, and tempests. During this dreadful season, THE EARTH. Ill the streets of cities flow like rivers ; and the whole country wears the appearance of an ocean. The inhabitants often make use of this opportunity to lay in a stock of fresh water, for the rest of the year; as the same cause which pours down the deluge at one season, denies the kindly shower at another. The thunder which attends the fall of these rains, is much more terrible than that we are generally acquainted with. With us the flash is seen at some distance, and the noise short- ly after ensues ; our thunder generally rolls on one quarter of the sky, and one stroke pursues another. But here it is otherwise; the whole sky seems illuminated with unrc- mitted ilishes of lightning; every part of the air stains productive of its own thunders; and every cloud produces its own shock. The strokes come so thick, that the inhabi- tants can scarcely mark the intervals; butall is one unremitted roar of elementary confusion. It should seem, however, that the lightning of those countries is not so fatal, or so dan- gerous, as with us ; since, in this case, the torrid zone would be uninhabitable. When these terrors have ceased, with which, however, the natives are familiar, me- teors of another kind begin to make their ap- pearance. The intense beams of the sun, darting upon stagnant waters, that generally cover the surface of the country, raise va- pours of various kinds. Floating bodies of fire, which assume different names, rather from their accidental forms, than from any real difference between them, are seen with- out surprise. The draco volans, or flying dragon, as it is called ; the ignis fatuus, or wandering fire; the fires of St. Helmo, or the ariner's light, are every where frequent ; and of these we have numberless descriptions. " As I was riding in Jamaica," says Mr. Barb- ham, " one morning from my habitation, situ- ated about three miles north-west from Jago de la Vega, I saw a ball of tire, appearing to me of the bigness of a bomb, swiftly falling down with a great blaze. At first I thought it fell into the town ; but when I came nearer, I saw many people gathered together, a little to the southward, in the savanna, to whom I rode up, to inquire the cause of their meet- ing: they were admiring, as I found, the ground's being strangely broke up and plough- ed by a ball of fire ; which, as they said, fell down there. I observed there were many holes in the ground ; one in the middle, of the bigness of a man's head, and five or six smaller roundabout it, ol the bigness of one's fist, and so deep as not to be fathomed by such implements as were at hand. It was observed also, that all the green herbage was burnt up, near the holes; and there conti- nued a strong smell of sulphur near the place, for some time after." Ulloa gives an account of one of a similar kind, at Quito.* " About nine at night," says he, " a globe of fire appeared to rise from the side of the mountain Pichinca, and so large, that it spread a light over all the part of the city facing that mountain. The house where I lodged looking that way, I was surprised with an extraordinary light, darting through the crevices of the window-shutters. On this appearance, and the bustle of the people in the street, I hastened to the window, and came time enough to see it, in the middle of its career; which continued from west to south, till I lost sight of it, being intercepted by a mountain, that lay between me and it. It was round ; and its apparent diameter about a foot. I observed it to rise from the sides of Pichinca ; although, to judge from its course, it was behind that mountain where this congeries of inflammable matter was kindled. In the first half of its visible course, it emitted a prodigious effulgence, then it be- gan gradually to grow dim ; so that, upon its disappearing behind the intervening moun- tain, its light was very faint." Meteors of this kind are very frequently seen between the tropics; but they some- times, also, visit the more temperate regions of Europe. We have the description of a very extraordinary one, given us by Monta- nari, that serves to show to what great heights, in our atmosphere, these vapours are found to ascend. In the year 1676, a great globe of fire was seen at Bononia, in Italy, about three quarters of an hour after sun-set. It passed westward, with a most rapid course, and at the rate of not less than a hundred and sixty miles in a minute, which is much swifter than the force of a cannon-ball, and, Ulloa, vol. i. p. 41. 112 A HISTORY OF at last, stood over the Adriatic sea. In its course it crossed over all Italy ; and, by com- putation, it could not have been less than thirty-eight miles above the surface of the earth. In the whole line of its course, wher- ever it approached, the inhabitants below could distinctly hear it, with a hissing noise, resembling that of a fire-work. Having pass- ed away to sea, towards Corsica, it was heard, at last, to go off with a most violent explosion, much louder than that of a cannon : and, im- mediately after, another noise was heard, like the rattling of a great cart upon a stony pave- ment ; which was, probably, nothing more than the echo of the former sound. Its mag- nitude, when at Bononia, appeared twice as long as the moon, one way, and as broad the other; so that, considering its height, it could not have been less than a mile long, and half a mile broad. From the height at which this was seen, and there being no volcano on that quarter of the world from whence it came, it is more than probable that this terrible globe was kindled on some part of the contrary side of the globe, in those regions of vapours which we have been just describing; and thus, rising above the air, and passing in a course oppo- site to that of the earth's motion, in this man- ner it acquired its amazing rapidity. To these meteors, common enough south- ward, we will add one more of a very uncom- mon kind, which was seen byUlloa, at Quito, in Peru; the beauty of which will, in some measure, serve to relieve us, after the descrip- tion of those hideous ones preceding. " At day break," says he, " the whole mountain of Pambamarca, where we then resided, was encompassed with very thick clouds ; which the rising of the sun dispersed so far, as to leave only some vapours, too fine to be seen. On the side opposite to the rising sun, and about ten fathoms distant from the place where we were standing, we saw, as in a looking-glass, each his own image ; the head being as it were, the centre of three circular rainbows, one without the other, and just near enough to each other as that the colours of the internal verged upon those more ex- ternal ; while round all was a circle of white, but with a greater space between. In this manner these circles were erected, like a mir- ror, before us ; and as we moved, they moved, in disposition and order. But what is most remarkable, though we were six in number, every one saw the phenomenon with regard to himself, and not that relating to others. The diameter of the arches gradually altered, as the sun rose above the horizon ; and the whole, after continuing a long time, insensibly faded away. In the beginning, the diameter of the inward iris, taken from its last colour, was about five degrees and a half; and that of the white arch, which surrounded the rest, was not less than sixty-seven degrees. At the beginning of the phenomenon, the arches seemed of an oval, or elliptical figure, like the disk of the sun ; and afterwards became per- fectly circular. Each of these was of a red colour, bordered with an orange ; and the last bordered by a bright yellow, which altered into a straw colour, and this turned to a green ; but, in all, the external colour remained red." Such is the description of one of the most beautiful illusions that has ever been seen in nature. This alone seems to have combined all the splendours of optics in one view. To understand the manner, therefore, how this phsenomenon was produced, would require a perfect knowledge of optics ; which it is not our present province to enter upon. It will be sufficient, therefore, only to observe, that all these appearances arise from the density of the cloud, together with its uncommon and peculiar situation, with respect to the specta- tor and the sun. It may be observed, that but one of these three rainbows was real, the rest being only reflections thereof. It may also be observed, that whenever the spectator stands between the sun and a cloud of fulling rain, a rainbow is seen, which is nothing more than the reflection of the different coloured rays of light from the bosom of the cloud. If, for instance, we take a glass globe, filled wit water, and hang it up before us opposite th sun, in many situations it will appear trans- parent ; but if it is raised higher, or sidewnys, to an angle of forty-five degrees, it will ot lirst appear red ; altered a very little higher, yellow ; then green, then blue, then violet colour: in short, it will assume surrossively all the colours of the rainbow ; but, if raisi d higher still, it will become transparent again. A falling shower may be considered as an infinite Dum- ber of these little transparent globes, assuming different colours, by being placed at their proper heights. The rest of the shower will THE EARTH. 113 appear transparent, and no part of it will seem coloured ; but such as are at angles of forty-five degrees from the eye, forty-rive de- grees upward, forty-five degrees on each side, and forty-five degrees downward, did not the plane of the earth prevent us. We therefore see only an arch of the rainbow, the lower part being cut ofFfrom our sight by the earth's interposition. However, upon the tops of very high mountains, circular rainbows are Been, because we can see to an angle of forty- five degrees downward, as well as upward, or sideways, and therefore we take in the rainbow's complete circle. In those forlorn regions round the poles, the meteors, though of another kind, are not less numerous and alarming. When the win- ter begins, and the cold prepares to set in, the same misty appearance which is pro- duced in the southern climates by the heat, is there produced by the contrary extreme." The sea smokes like an oven, and a fog arises, which mariners call the frost smoke. This cutting mist commonly raises blisters on several parts of the body ; and, as soon as it is wafted to some colder part of the atmos- phere, it freezes to little icy particles, which are driven by the wind, and creates such an intense cold on land, that the limbs of the inhabitants are sometimes frozen, and drop off There, also, halos, or luminous circles round the moon, are oftener seen than in any other part of the earth, being formed by the frost smoke ; although the air otherwise seems to be clear. A lunar rainbow also is often seen there, though somewhat different from that which is common with us ; as it ap- irs of a pale white, striped with gray. In se countries also, the aurora borealis streams with peculiar lustre, and variety of colours. In Greenland it generally arises in the east, and darts its sportive fires, with va- riegated beauty, over the whole horizon. Its appearance is almost constant in winter; and at those seasons when the sun departs, to return no more for half a year, this meteor | kindly rises to supply its beams, and affords sufficient light for all the purposes of exis- tence. However, in the very midst of their Paul Egede's History of Greenland. tedious night, the inhabitants are not entirely forsaken. The tops of the mountains are of- ten seen painted with the red rays of the sun ; and the poor Greenlander from thence begins to date his chronology. It would appear whimsical to read a Greenland calendar, in which we might be told, That one of their chiefs, having lived forty days, died, at last, of a good old age ; and that his widow con- tinued for half a day to deplore his loss, with great fidelity, before she admitted a second husband. The meteors of the day, in these countries, are not less extaordinary than those of the night : mock suns are often reflected upon an opposite cloud ; and the ignorant spec- tator fancies that there are often three or four real suns in the firmament at the same time. In this splendid appearance the real sun is always readily known by its superior brightness, every reflection being seen with diminished splendour. The solar rainbow there, is often seen different from ours. In- stead of a pleasing variety of colours, it ap- pears of a pale white, edged with a stripe of dusky yellow; the whole being reflected from the bosom of a frozen cloud. But, of all the meteors which mock the imagination with an appearance of reality, those strange illusions that are seen there, m fine serene weather, are the most extraor- dinary and entertaining. " Nothing," says Krantz, " ever surprised me more, than on a fine warm summer,s day, to perceive the islands that lie four leagues west of our shore, putting on a form quite different from what they are known to have. As I stood gazing upon them, they appeared at first infinitely greater than what they naturally are ; and seemed as if I viewed them through a large mag- nifying glass. They were not thus only made larger, but brought nearer to me. I plainly descried every stone upon the land, and all the furrows filled with ice, as if I stood close by. When this illusion had lasted for a while, the prospect seemed to break up, and a new scene of wonder to present itself. The island seemed to travel to the shore, and re- presented a wood, or a tall cut hedge. The scene then shifted, and showed the ap- pearance of all sorts of curious figures ; as ships with sails, streamers, and flags ; antique J14 A HISTORY OF elevated castles, with decayed turrets ; and a thousand forms, for which fancy, .found a resemblance in nature. When the eye had been satisfied with gazing, the whole group of riches seemed to rise in air, and at length vanish into nothing. At such times the wea- ther is quite serene and clear; but compressed with such subtle vapours, as it is in very hot weather ; and these appearing between the eye and the object, give it all that variety of appearances which glasses of different re- frangibilities would have done." Mr. Krantz observes, that commonly a couple of hours afterwards, a gentle west wind and a visible mist follow, which put an end to this lusus natures. It were easy to swell this catalogue of me- teors with the names of many others, both in our own climate and in other parts of the world. Such as falling stars, which are thought to be no more than unctuous vapours, raised from the earth to small heights, and continuing to shine till that matter which first raised and supported them, being burnt out, they fall back again to the earth, with ex- tinguished flame. Burning spears, which are a peculiar kind of aurora borealis; bloody rains, which are said to be the excrements of an insect, that at that time has been raised into the air. Showers of stones, fishes, and ivy-berries, at first, no doubt, raised into the air by tempests in one country, and falling at some considerable distance, in the manner of rain, to astonish another. But omitting these, of which we know little more than what is thus briefly mentioned, I will conclude this chapter with the description of a water-spout; a most surprising phenomenon ; not less dreadful to mariners, than astonishing to the observer of nature. These spouts are seen very commonly in the tropical seas, and sometimes in our own. Those seen by Tournefort, in the Mediterra- nean, he has described as follows : " The first of these," says this great botanist, " that we saw, was about a musket-shot from our ship. There we perceived the water began to boil, and to rise about a foot above its level. The water was agitated and whitish ; and, above its surface, there seemed to stand a smoke, such as might be imagined to come from wet straw before it begins to blaze. It made a sort of a murmuring sound, like that of a torrent heart at a distance, mixed, at the same time, with a hissing noise, like that of a serpent: shortly after, we perceived a co- lumn of this smoke rise up to the clouds, at the same time whirling about with great rapi- dity. It appeared to be as thick as one's fin- ger; and the former sound still continued. When this disappeared, after lasting forabout eight minutes, upon turning to the opposite quarter of the sky, we perceived another, which began in the manner of the former ; presently after, a third appeared in the west ; and instantly beside it still another arose. The most distant of these three could not be above a musket-shot from the ship. They all continued like so many heaps of wet straw set on fire, that continued to smoke, and to make the same noise as before. We soon after perceived each, with its respective canal, mounting up in the clouds, and spreading where it touched ; the cloud, like the mouth of a trumpet, making a figure, to express it intelligibly, as if the tail of an animal were pulled at one end by a weight. These canals were of a whitish colour, and so tinged, as I suppose, by the water which was contained in them; for, previous to this, they were ap- parently empty, and of the colour of transpa- rent glass. These canals were not straight, but bent in some parts, and far from being perpendicular, but rising in their clouds with a very inclined ascent. But what is very par- ticular, the cloud to which one of them was pointed happening to be driven by the wind, the spout still continued to follow its motion, without being broken ; and passing behind one of the others, the spouts crossed each other, in the form of a St. Andrew's cross. Iji the beginning they were all about as thick aP one's finger, except at the top, where they were broader, and two of them disappeared ; but shortly after, the last of the three increased considerably; and its canal, which was at first so small, soon became as thick as a man's arm, then as his leg, and, at last, thicker than his whole body. We saw distinctly, through this transparent body, the water, which rose up with a kind of spiral motion; and it some- times diminished a little of its thickness, and again resumed the same ; sometimes widen- ing at top, and sometimes at bottom ; exactly THE EARTH 115 resembling a gut filled with water, pressed with the fingers, to make the fluid rise, or fall ; and I am well convinced that this alteration in the spout w is caused by the wind, which pressed the cloud, and impelled it to give up its contents. After some time its bulk was so diminished as to be no thicker than a man's arm again ; and thus, swelling and diminishing, it at last became very small. In the end, I observed the sea which was raised about it to resume its level by degrees, and the end of the canal that touched it to become as small as if it had been tied round with a cord ; and this continued till the light, striking through the cloud, took away the view. I still, however, continued to look, expecting that its parts would join again, as I had be- fore seen in one of the others, in which the spout was more than once broken, and yet again came together ; but I was disappointed, for the spout appeared no more." Many have been the solutions offered for this surprising appearance. Mr. Buffbn sup- poses the spout, here described, to proceed irorn the operation of fire, beneath the bed of the sea ; as the waters at the surface are thus seen agitated. However, the solution of Dr. Stuart is not divested of probability ; who thinks it may be accounted for by suction, as in the application of a cupping-glass to the skin. Wherever spouts of this kind are seen, they are extremely dreaded by mariners; for if they happen to fall upon a ship, they most commonly dash it to the bottom. But, if the ship be large enough to sustain the deluge, they are at least sure to destroy its sails and rigging, and render it unfit for sailing. It i< aid that vessels of any force usually fire their guns at them, loaden with a bar of iron ; and if so happy as to strike them, the water is instantly seen to fall from them, with a dread- ful noise, though without any farther mischief. I am at a loss whether we ought to reckon these spouts called typhous, winch are some- times seen at land, of the same kind with those so often described by mariners at sea, as they seem to differ in several respects. That, for instance, observed at Hatfield, in Yorkshire, in 1687, as it is described by the person who aw it, seems rather to have been a whirl- wind than a water-spout The season in MO. 11 & 12. which it appeared was very dry, the weather extremely hot, and the air very cloudy. After the wind had blown for some time with con- siderable force, and condensed the black clouds one upon another, a great whirling of the air ensued ; upon which the centre of the clouds, every now and then, darted down in the shape of a thick long black pipe; in which the relator could distinctly view a mo- tion, like that of a screw, continually screw- ing up to itself, as it were, whatever it hap- pened to touch. In its progress it moved slowly over a grove of young trees, which it violently bent in a circular motion. Going forward to a barn, it in a minute stript it of all the thatch, and filled the whole air with the same. As it came near the relator, he perceived that its blackness proceeded from a gyration of the clouds, by contrary winds meeting in a point, or a centre ; and where the greatest force was exerted, there darting down, like an Archimedes' screw, to suck up all that came in its way. Another which he saw, some time after, was attended with still more terrible effects ; levelling or tear- ing up great oak-trees, catching up the birds in its vortex, and dashing them against the ground. In this manner it proceeded with an audible whirling noise, like that of a mill ; and at length dissolved, after having done much mischief. But we must still continue to suspend our assent as to the nature even of these land spouts, since they have been sometimes found to drop, in a great column of water, at once upon the earth, and produce an instant inun- dation," which could not readily have hap- pened had they been caused by the gyration of a whirlwind only. Indeed, every conjec- ture regarding these meteors, seems to me entirely unsatisfactory. They sometimes ap- pear in the calmest weather at sea, of which I have been an eye-witness ; and, therefore, these are not caused by a whirlwind. They are always capped bya cloud; and, therefore, are not likely to proceed from fires at the bottom. They change place ; and, therefore, suction seems impracticable. In short, we still want facts, upon which to build a ra- tional theory ; and, instead of knowledge, we Phil. Trans, vol. iv. p. 108. 2B 116 A HISTORY OF must be contented with admiration. To be well acquainted with the appearances of na- ture, even though we are ignorant of their causes, often constitutes the most useful wisdom.* [But among all the wonders that have late- ly engaged the attention of the philosopher and the chemist, is the circumstance, that after the explosion of these luminous meteors, heavy stones, varying in bulk and number, have almost constantly fallen from them to the earth. Credibility in a fact, for which not even a conjectural cause in the remotest degree probable could be assigned, was for some time suspended : but the proofs are now so numerous, and of such respectable authority, that it can no longer be doubted. In the year 1794, Dr. Chaldni published a dissertation on this subject; and two years afterwards Mr. King produced a still more complete collection of examples, both ancient and modern, many of them supported by such evidence, that even scepticism could no longer refuse its consent. Mr. Howard, in the Philosophical Transactions for 1802, published an admirable treatise, endeavour- ing to throw all possible light upon a subject BO singular and interesting. He not only col- lected all the recent and well-authenticated accounts of the fall of the stony bodies, and examined the evidence of their truth, but pro- cured specimens of the stones which were said to have fallen in different places, com- pared them together, and subjected them to [ a Dr. Franklin supposes a water-spout and a whirlwind to proceed from the same cause : a fluid moving from all points horizontally towards a centre, must at that centre either mount or descend. If a hole be opened in the middle of the bottom of a tub filled with water, the water will flow from all sides to the centre, and then de- scend in a whirl : but the air flowing on or near the sur- face of land or water, from all sides towards a centre, must at that centre ascend, because the land or water will hinder descent. The lower region of the air is often more heated, and o more rarefied, than the upper, and consequently spe- cifically lighter : if therefore a large tract of land or sea, unsheltered by clouds, and unrufiled by wind, become violently heated and rarefied, so that the lower region become lighter than the superincumbent upper one, the heated lighter air will ascend like smoke up a chimney; and as this rising cannot operate through the whole tract at once, because that would leave too extensive a vacuum, the rising will begin in that column which happens to be most rarefied ; and the warm air will flow horizontally chemical analysis. It may here be proper to give a few of the more recent instances, with the testimonies upon which they rest. In July, 1794, about twelve stones fell near Sienna in Tuscany, as related by the Earl of Bristol. December 13, 1795, a large stone of fifty-six pounds weight, fell at W old cot- tage in Yorkshire, and is described by cap- tain Topham. February 19, 1796, a stone of ten pounds weight fell in Portugal, an account of which is given by Mr. Southey. December 19, 1798, showers of stones fell at Benares in the East Indies, upon the testimony of J.Lloyd Williams, Esq. April 26, 1803, according toM. Fourcroy, several stones, from ten to fourteen pounds weight, fell near L'Aigle in Normandy. In corrohoration of these facts, it appears, that whether they have fallen in England, France, Italy, Germany, or India, they are all composed of the same ingredients, all re- semble each other, and completely differ from any other known stone. Sometimes the stones continue luminous till they sink into the earth, but most commonly their luminous- ness disappears at the time of explosion: but they are always found hot. Their size differs from a few ounces to several tons ; they are usually of a roundish form, and always co- vered with a black crust. When broken they appear of an ashy-gray colour, and of a gran- ular texture, like a coarse sand-stone, and have an earthy srnell. A stone which fell in Yorkshire, deprived as much as possible of its metallic particles, from all parts of this column, where the several currents meeting, a whirl or eddy is naturally formed, ascending by a spiral motion, in the same manner as water descends spirally through the hole in the tub. If the vacuum passes over water, the water may rise in a body or column to the height of about 32 feet ; and this whirl of air may be as invisible as air itself. As the whirl weakens, the tube may apparently separate in the middle ; the column of water subsiding, the superior con- densed part drawing up to the cloud. The tube or whirl of air may nevertheless remain entire, the middle only becoming invisible, as not containing any visible matter. The author has, frequently, in a fine calm summer's day, when the sun has been very hot, and the atmosphere unrufiled by winds, seen sheaves of corn, hay-cocks, and other moveable substances, suddenly lifted up with a cir- cular motion, and carried to a considerable distance : and in a blazing fire, where the (!ame and smoke are carried up through a small chimney, if a piece of paper or other very light substance be put into the flame, it will be lifted up the chimney with a spiral motion.] THE EARTH. 117 according to Mr. Howard, produced from one hundred and fifty grains, seventy-five of siliceous earth, thirty-seven of magnesia, forty-eight of oxyde, or calx of iron, and two of oxyde, or calx of nickell ; leaving an ex- cess from its original weight of twelve grains, owing to the oxydation of the metallic bodies. Various conjectures have been made, to account for their appearance ; but such is the obscurity of the subject, that no opinion in the slightestdegree probable has yet been ad- vanced. It was at first supposed, that they had been thrown out of volcanoes, but the immense distance from all volcanoes renders this opinion of little value. Chaldni endea- voured to prove, that the meteors from which they fell, were bodies floating in space, un- connected with any planetary system, at- tracted by the earth in their progress, and kindled by their rapid motion in the atmos- phere. Laplace suggests the probability of their having been thrown off by the volcanoes of the moon ; but the meteors which almost always accompany them, and the swiftness of their horizontal motion, persuade us to re- ject this opinion. Sir William Hamilton, and Mr. King, with greater probability con- sider them as concretions actually formed in the atmosphere. In addition to these, the showers of sulphur which are related to have occasionally fallen, and the vast masses of iron found in South America, and Siberia, are supposed to have their origin from the same causes : for it is a singular coincidence, that these pieces of iron contain nickell, which has never been known to be present in real native iron. Upon the whole, we can only look with ignorant astonishment, and at present con- sider these stony and metallic masses as frag- ments of meteoric fire-balls, which have burst in the atmosphere, the origin and causes of which must be left to the accumulated wis- dom and inquiry of future ages.] CHAPTER XXn. THE CONCLUSION. HAVING thus gone through a particular description of the earth, let us now pause for a moment, to contemplate the great picture before us. The universe may be considered as the palace in which the Deity resides ; and this earth as one of its apartments. In this, all the meaner races of animated nature mechanically obey him ; and stand ready to execute his commands without hesitation. Man alone is found refractory ; he is the only being endued with a power of contradicting these mandates. The Deity was pleased to exert superior power in creating him a su- perior being ; a being endued with a choice of good and evil ; and capable, in some mea- sure, of co-operating with his own intentions. Man, therefore, may be considered as a limited creature, endued with powers imita- tive of those residing in the Deity. He is thrown into a world that stands in need of his help ; and has been granted a power of producing harmony from partial confu- sion. If, therefore, we consider the earth as al- lotted for our habitation, we shall find that much has been given us to enjoy, and much to amend ; that we have ample reasons for our gratitude, and still more for our industry. In those great outlines of nature, to which art cannot reach, and where our greatest efforts must have been ineffectual, God himself has finished these with amazing grandeur and beauty. Our beneficent Father has consi- dered these parts of nature as peculiarly his own ; as parts which no creature could have skill or strength to amend: and, therefore, made them incapable of alteration, or of more perfect regularity. The heavens and the fir- mament show the wisdom and the glory of the Workman. Astronomers, who are best skilled in the symmetry of systems, can find nothing there that they can alter for the bet- 2 B* 118 A HISTORY OF ter. God made these perfect, because no subordinate being could correct their de- fects. When, therefore, we survey nature on this .side, nothing can be more splendid, more cor- rect, or amazing. We there behold a Deity residing in the midst of an universe, infinitely extended every way, animating all, and cheer- ing the vacuity with his presence ! We behold an immense and shapeless mass of matter, formed into worlds by his power, and dis- persed at intervals, to which even the imagi- nation cannot travel ! In this great theatre of his glory, a thousand suns, like our own, ani- mate their respective systems, appearing and vanishing at divine command. We behold our own bright luminary, fixed in the centre of its system, wheeling its planets in times proportioned to their distances, and at once dispensing light, heat, and action. The earth also is seen with its twofold motion; pro- ducing, by the one, the change of seasons; and, by the other, the grateful vicissitudes of day and night. With what silent mag- nificence is all this performed ! with what Beeming ease ! The works of art are exerted with interrupted force ; and their noisy pro- gress discovers the obstructions they receive: but the earth, with a silent steady rotation, successively presents every part of its bosom to the sun; at once imbibing nourishment and light from that parent of vegetation and fertility. But not only provisions of heat and light are thus supplied, but its whole surface is covered with a transparent atmosphere, that turns with its motion, and guards it from ex- ternal injury. The rays of the sun are thus broken into a genial warmth ; and, while the surface is assisted, a gentle heat is produced in the bowels of the earth, which contributes to cover it with verdure. Waters also are supplied in healthful abundance, to support life, and assist vegetation. Mountains arise, to diversify the prospect, and give a current to the stream. Seas extend from one conti- nent to the other, replenished with animals that may be turned to human support; and also serving to enrich the earth with a suf- ficiency of vapour. Breezes fly along the surface of the nVlds, to promote health and vegetation. The coolness of the evening in- vites to rest; and the freshness of the morn- ing renews for labour. Such are the delights of the habitation that has been assigned to man ; without any one of these, he must have been wretched ; and none of these could his own industry have supplied. But while many of his wants are thus kindly furnished on the one hand, there are numberless inconveniences to excite his industry on the other. This habitation, though provided with all the conveniences of air, pasturage, and water, is but a desert place, without human cultivation. The lowest animal finds more conveniences in the wilds of nature than he who boasts himself their lord. The whirlwind, the inundation, and all the asperities of the air, are peculiarly terrible to man, who knows their conse- quences, and, at a distance, dreads their ap- proach. The earth itself, where human art has not pervaded, puts on a frightful gloomy appearance. The forests are dark and tang- led; the meadows overgrown with rank weeds; and the brooks stray without a determined channel. Nature, that has been kind to every lower order of beings, has been quite neg- lectful with regard to him ; to the savage uncontriving man the earth is an abode of desolation, where his shelter is insufficient, and his food precarious. A world thus furnished with advantages ou one side, and inconveniences on the other, is the proper abode of reason, is the fittest to exercise the industry of a free and a thinking creature. These evils, which art can re- medy, and prescience guard against, are a proper call for the exertion of his faculties; and they tend still more to assimilate him to his Creator. God beholds with pleasure that being which he has made, converting the wretchedness of his natural situation into a theatre of triumph ; bringing all the headlong tribes of nature into subjection to his will; and producing that order and uniformity upon earth, of which his own heavenly fabric is BO bright an example. ANIMALS. 119 CHAPTER A COMPARISON OF ANIMALS WITH THE INFERIOR RANKS OF CREATION. HAVING given an account of the earth in general, and the advantages and incon- veniences with which it abounds, we now come to consider it more minutely. Having described the habitation, we are naturally led to i '.quire alter the inhabitants. Amidst the infinitely different productions which the earth offers, and with which it is every where covered, animals hold the first rank ; as well because of the liner formation of their parts, as of their superior power. The vegetable, which is fixed to one spot, and obliged to wait for its accidental supplies of nourishment, may be considered as the prisoner of nature. Unable to correct the disadvantages of its si- tuation, or to shield itself from the dangers that surround it, every object that has motion may be its destroyer. But animals are endowed with powers of motion and defence. The greatest part are capable, by changing place, of commanding nature; and of thus obliging her to furnish that nourishment which is most agreeable to their state. Those few that are fixed to one spot, even in this seemingly helpless situation, are, nevertheless, protected from external in- jury by a hard shelly covering ; which they often can close at pleasure, and thus defend themselves from every assault. And here, I think, we may draw the line between the animal and vegetable kingdoms. Every ani- mal, by some means or other, finds protec- tion from injury; either from its force, or cou- rage, its swiftness, or cunning. Some are pro- tected by hiding in convenient plac-s ; and others by taking refuge in a hard resisting shell. But vegetables are totally unprotect- ed ; they are exposed to every assailant, and patiently submissive in every attack. In a word, an animal is an organized being, thai is in some measure provided for its own secu- rity ; a vegetable is destitute of every protec- tion. But though it is very easy, without the help of definitions, to distinguish a plant from an animal, yet both possess many properties so much alike, that the two kingdoms, as they are called, seemed mixed with each other. Hence, it frequently puzzles the naturalist to tell exactly where animal life begins, and vege- tative terminates; nor, indeed, is it easy to re- solve, whether some objects offered to view be of the lowest of the animal, or the highest of the vegetable races. The sensitive plant, that moves at the touch, seems to have as much perception as the fresh-water polypus, that is possessed of a still slower share of motion. Besides, the sensitive plant will not repro- duce upon cutting in pieces, which the poly- pus is known to do; so that the vegetable production seems to have the superiority. But, notwithstanding this, the polypus hunts for its food, as most other animals do. It changes its situation ; and, therefore, pos- sesses a power of choosing its food, or retreat- ing from danger. Still, therefore, the animal kingdom is far removed above the vegetable; and its lowest denizen is possessed of very great privileges, when compared with the plants with which it is often surrounded. However, both classes have many resem- blances, by which they are raised above the unorganized and inert masses of nature. Mi- nerals are mere inactive, insensible bodies, entirely motionless of themselves, and wait- ing some external force to alter their forms, 120 A HISTORY OF or their properties. But it is otherwise with animals and vegetables ; these are endued with life and vigour : they have their state of improvement and decay ; they are capable of reproducing their kinds ; they grow from seeds in some, and from cuttings in others ; they seem all possessed of sensation, in a greater or less degree ; they both have their enmities and affections ; and, as some animals are, by nature, impelled to violence, so some plants are found to exterminate all others, and make a wilderness of the places round them. As the lion makes a desert of the forest where it resides, thus no other plant will grow under the shade of the manchineel- tree. Thus, also, that plant, in the West Indies, called caraguata, clings round what- ever tree it happens to approach : there it quickly gains the ascendant; and, loading the tree with a verdure not its own, keeps away that nourishment designed to feed the trunk; and, at last, entirely destroys its sup- porter. As all animals are ultimately sup- ported upon vegetables, so vegetables are greatly propagated, by being made a part of animal food. Birds distribute the seeds wher- ever they fly, and quadrupeds prune them into greater luxuriance. By these means the quantity of food, in a state of nature, is kept equal to the number of the consumers ; and, lest some of the weaker ranks of animals should find nothing for their support, but all the provisions be devoured by the strong, different vegetables are appropriated to dif- ferent appetites. If, transgressing this rule, the stronger ranks should invade the rights of the weak, and, breaking through all regard to appetite, should make an indiscriminate use of every vegetable, nature then punishes the transgression, and poison marks the crime as capital. If, again, we compare vegetables and ani- mals, with respect to the places where they are found, we shall find them bearing a still stronger similitude. The vegetables that grow in a dry and sunny soil, are strong and vigo- rous, though not luxuriant ; so, also, are the animals of such a climate. Those, on the contrary, that are the joint product of heat and moisture, are luxuriant and tender ; and the animals assimilating to the vegetable food, on which they ultimately subsist, are much larger in such places than in others. Thus, in the internal parts of South America and Africa, where the sun usually scorches all above, while inundations cover all below, the insects, reptiles, and other animals, grow to a prodigious size: the earth-worm of America is often a yard in length, and as thick as a walking cane; the boiguacu, which is the largest of the serpent kind, is sometimes forty feet in length; the bats, in those countries, are as big as a rabbit ; the toads are bigger than a duck ; and their spiders are as large as a sparrow. On the contrary, in the cold frozen regions of the north, where vegetable nature is stinted of its growth, the few ani- mals in those climates partake of the diminu- tion ; all the wild animals, except the bear, are much smaller than in milder countries ; and such of the domestic kinds as are car- ried thither, quickly degenerate, and grow, less. Their very insects are of the minute kinds, their bees and spiders being not half so large as those in the temperate zone. The similitude between vegetables and animals is no where more obvious than in those that belong to the ocean, where the nature of one is admirably adapted to the necessities of the other. This element, it is well known, has its vegetables, and its insects that feed upon them in great abun- dance. Over many tracts of the sea, a weed is seen floating, which covers the surface, and gives the resemblance of a green and exten- sive meadow. On the under side of these unstable plants, millions of little animals are found, adapted to their situation. For, aa their ground, if I may so express it, lies over their heads, their feet are placed upon their backs; and, as land animals have their legs below their bodies, these have them above. At land also, most animals are furnished with eyes to see their food ; but at sea, almost all the reptile kinds are without eyes, which might only give them prospects of danger at a time when unprovided with the means of escaping it." Thus, in all places, we perceive an ob- vious similitude between the animals and the vegetables of every region. In general, how- ever, the most perfect races have the least Linnrei Amccnitates, vol. v. p. 68. ANIMALS. 121 similitude to the vegetable productions on which they are ultimately fed; while, on the contrary, the meaner the animal, the more local it is found to be, and the more it is influ- enced by the varieties of the soil where it resides. Many of the more humble reptile kinds are not only confined to one country, but also to a plant ; nay, even to a leaf. Upon that they subsist; increase with its vegeta- tion, and seem to decay as it declines. They are merely the circumscribed inhabitants of a single vegetable : take them from that, and they instantly die ; being entirely assimilat- ed to the plant they feed on, assuming its co- lour, and even its medicinal properties. For this reason, there are infinite numbers of the meaner animals that we have never an op- portunity of seeing in this part of the world ; they are incapable of living separate from their kindred vegetables, which grow only in a certain climate. Such animals as are formed more perfect, lead a life of less dependance; and some kinds are found to subsist in many parts of the world at the same time. But, of all the races of animated nature, man is the least affected by the soil where he resides, and least influenced by the variations of vegeta- ble sustenance : equally unaffected by the luxuriance of the warm climates, or the steri- lity of the poles, he has spread his habitations over the whole earth ; and finds subsistence as well amidst the ice of the north as the burning deserts under the Line. All crea- tures of an inferior nature, as has been said, have peculiar propensities to peculiar cli- mates ; they are circumscribed to zones, and confined to territories, where their proper food is found in the greatest abundance; but man may be called the animal of every cli- mate, and suffers but very gradual alterations from the nature of any situation. As to animals of a meaner rank, whom man compels to attend him in his migrations, these being obliged to live in a kind of con- straint, and upon vegetable food, often differ- ent from that of their native soil, they very soon alter their natures with the nature of their nourishment, assimilate to the vegeta- bles upon which they are fed, and thus as- sume very different habits as well as appear- ances. Thus man, unaffected himself, alters and directs the nature of other animals at his pleasure ; increases their strength for his de- light, or their patience for his necessities. This power of altering the appearances of things, seems to have been given him for very wise purposes. The Deity, when he made the earth, was willing to give his favoured creature many opponents, that might at once exercise his virtues, and call forth his latent abilities. Hence we find, in those wide un- cultivated wildernesses, where man, in his savage state, owns inferior strength, and the beasts claim divided dominion, that the whole forest swarms with noxious animals and vegetables ; animals, as yet undescri- bed, and vegetables which want a name. In those recesses, nature seems rather lavish than magnificent in bestowing life. The trees are usually of the largest kinds, covered round with parasite plants, and interwoven at the tops with each other. The boughs, both above and below, are peo- pled with various generations ; some of which have never been upon the ground, and others have neK.er stirred from the branches on which they were produced. In this manner millions of minute and loathsome creatures pursue a round of uninterrupted existence,and enjoy a life scarcely superior to vegetation. At the same time, the vegetables in those places are of the larger kinds, while the animal race is of the smaller : but man has al- tered this disposition of nature ; having, in a great measure, levelled the extensive forests, cultivated the softer and finer vegetables, de- stroyed the numberless tribes of minute and noxious animals, and taken every method to increase a numerous breed of the larger kinds. He thus has exercised a severe con- trol ; unpeopled nature, to embellish it ; and diminished the size of the vegetable, in or- der to improve that of the animal kingdom. To subdue the earth to his own use was, and ought to be, the aim of man ; which was only to be done by increasing the number of plants, and diminishing that of animals : to multiply existence, alone was that of the Deity. For this reason, we find, in a state of nature, that animal life is increased to the greatest quantity possible; and, we can scarcely form a system that could add to its numbers. First, plants or trees are pro- 122 A HISTORY OF vided by nature, of the largest kinds ; and, consequently, the nourishing surface is thus extended. In the second place, there are animals peculiar to every part of the vegeta- ble, so that no part of it is lost. But the greatest possible increase of life would still be deficient, were there not other animals that lived upon animals; and these are, themselves, in turn, food for some other greater and stronger set of creatures. Were all animals to live upon vegetables alone, thousands would be extinct that now have existence, as the quantity of their provision would shortly fail. But, as things are wisely constituted, one animal now supports ano- ther ; and thus, all take up less room than they would by living on the same food ; as, to make use of a similar instance, a greater number of people may be crowded into the same space, if each is made to bear his fel- low upon his shoulders. To diminish the number of animals, and increase that of vegetables, has been the ge- neral scope of human industry ; and, if we compare the utility of the kinds, with respect to man, we shall find, that of the vast va- riety in the animal kingdom, but very few are serviceable to him ; and, in the vegetable, but very few are entirely noxious. How small a part of the insect tribes, for instance, are beneficial to mankind, and what numbers are injurious ! In some countries they almost darken the air : a candle cannot be lighted without their instantly flying upon it, and putting out the flame." The closest recesses are no safeguard from their annoyance ; and the most beautiful landscapes of nature only serve to invite their rapacity. As these are injurious, from their multitudes, so most of the larger kinds are equally dreadful to him, from their courage and ferocity. In the most uncultivated parts of the forest these main- tain an undisputed empire ; and man invades Ulloa's Description of Guayaquil. their retreats with terror. These are dread- ful; and there are still more which are utter- ly useless to him, that serve to take up the room which more beneficial creatures might possess; and incommode him, rather with their numbers than their enmities. Thus, in a catalogue of land-animals, that amounts to more than twenty thousand, we can scarcely reckon up a hundred that are any way use- ful to him ; the rest being either all his open or his secret enemies, immediately attacking him in person, or intruding upon that food he has appropriated to himself. Vegetables, on the contrary, though existing in greater vari- ety, are but few of them noxious. The most deadly poisons are often of great use in me- dicine ; and even those plants that only seern to cumber the ground, serve for food to that race of animals which he has taken into friendship or protection. The smaller tribes of vegetables, in particular, are cultivated, as contributing either to his necessities or amusement ; so that vegetable life is as much promoted by human industry, as animal life is controlled and diminished. Hence it was not without a long struggle, and various combinations of experience and art, that man acquired his present dominion. Almost every good that he possesses was the result of the contest ; for, every day, as he was contending, he was growing more wise; and patience and fortitude were the fruits of his industry. Hence, also, we see the necessity of some animals living upon each other, to fill up the plan of Providence ; and we may, conse- quently, infer the expediency of man's living upon all. Both animals and vegetables seem equally fitted to his appetites ; and were any religious or moral motives to restrain him from taking away life, upon any account, he would only thus give existence to a variety of beings made to prey upon each other; and, instead of preventing, multiply mutual destruction. ANIMALS. 123 CHAPTER XXIV. OF THE GENERATION OF ANIMALS. BEFORE we survey animals in their state of maturity, and performing the functions adapted 10 their respective natures, method requires that we should consider them in the more early periods of their existence. There has been a time when the proudest and the noblest animul was a partaker of the same imbecility with the meanest reptile; and, while yet a candidate for existence, equally helpless and contemptible. In their inci- pient state, all are upon a footing ; the insect and the philosopher being equally insensible, clogged with matter, and unconscious of ex- istence. Where then are we to begin with the history of those beings, that make such a distinguished figure in the creation ? Or, where lie those peculiar characters in the parts that go to make up animated nature that mark one animal as destined to creep in the dust, and another to glitter on the throne ? This has been a subject that has employ- ed the curiosity of all ages, and the philoso- phers of every age have attempted the so- lution. In tracing nature to her most hidden recesses, she becomes too minute or obscure for our inspection ; so that we find it impos- sible to mark her first differences, to discover the point where animal life begins, or the cause that conduces to set it in motion. We know little more than that the greatest num- ber of animals require the concurrence of a male arid female to reproduce their kind ; and that these, distinctly and invariably, are found to beget creatures of their own species. Curiosity has, therefore, been active in try- ing to discover the immediate result of this union ; how far either sex contributes to the bestowing animal life, and whether it be to the male or female that we are most indebt- ed for the privilege of our existence. Hippocrates has supposed that fecundity proceeded from the mixture of the seminal liquor of both sexes, each of which equally contributes to the formation of the incipient animal. Aristotle, on the other hand, would have the seminal liquor in the male alone to contribute to this purpose, while the female supplied the proper nourishment for its sup- port. Such were the opinions of these fa- thers of philosophy ; and these continued to be adopted by the naturalists and schoolmen of succeeding ages, with blind veneration. At length, Steno and Harvey, taking anatomy for their guide, gave mankind a nearer view of nature just advancing into animation. These perceived, in all such animals as pro- duced their young alive, two glandular bo- dies, near the womb, resembling that ovary, or cluster of small eggs, which is found in fowls ; and from the analogy between both, they gave these also the name of ovaria. These, as they resembled eggs, they natural- ly concluded had the same offices ; and, therefore, they were induced to think that all animals, of what kind soever, were produced from eggs. At first, however, there was some altercation raised against this system : for, as these ovaria were separate from the womb, it was objected that they could not be any way instrumental in replenishing that organ, with which they did not communicate. But, upon more minute inspection, Fallopius, the anatomist, perceived two tubular vessels depending from the womb, which, liku the horns of a snail, had a power of erecting themselves, of embracing the ovaria, and of receiving the eggs, in order to be fecundated by the seminal liquor. This discovery seem- ed, for a long time after, to fix the opinions of philosophers. The doctrine of Hippocrates was re-established, and the chief business of generation was ascribed to the female. This was for a long time the established opinion of the schools; but Leuwenhoeck, once more, shook the whole system, and produced a new schism among the lovers of specula- tion. Upon examining the seminal liquor of a great variety of male animals with mi- croscopes, which helped his sight more than that of any of his successors, he perceived 2C 121 A HISTORY OF therein infinite numbers of little living crea- tures, like tadpoles, very brisk, and floating in the fluid with a seeming voluntary motion. Each of these, therefore, was thought to be the rudiments of an animal, similar to that from which it was produced ; and this only required a reception from the female, toge- ther with proper nourishment, to complete its growth. The business of generation was now, therefore, given back to the male a se- cond time, by many; while others suspended their assent, and chose rather to confess ig- norance than to embrace error.* In this manner has the dispute continued for several ages, some accidental discovery serving, at intervals, to renew the debate, and revive curiosity. It was a subject where speculation could find much room to display itself; and Mr. Buffon, who loved to specu- late, would not omit such an opportunity of giving scope to his propensity. According to this most pleasing of all naturalists, the mi- croscope discovers that the seminal liquor, not only ot males, but of females also, abounds in these moving little animals, which have been mentioned above, and that they appear equally brisk in either fluid. These he takes not to be real animals, but organical parti- cles, which, being simple, cannot be said to be organized themselves, but go to the com- position of all organized bodies whatsoever; in the same manner as a tooth, in the wheel of a watch, cannot be called either the wheel or the watch, and yet contributes to the sum of the machine. These organical particles are, according to him, diffused throughout all nature, and to be found not only in the semi- nal liquor, but in most other fluids in the parts of vegetables, and all parts of animated nature. As they happen, therefore, to be dif- ferently applied, they serve to constitute a part of the animal, or the vegetable, whose growth they serve to increase, while the su- perfluity is thrown off* in the seminal liquor of both sexes, for the reproduction of other animals or vegetables of the same species. These particles assume different figures, ac- cording to the receptacle into which they enter ; falling into the womb, they unite into a fostus ; beneath the bark of a tree they pul- Bonnet Considerations sui les Corps Organises. lulate into branches; and, in short, the same particles that first formed the animal in the womb, contribute to increase its growth when brought forth.' 1 To this system it has been objected, that it is impossible to conceive organical sub- stances without being organized ; and that, if divested of organization themselves, they could never make an organized body, as an infinity of circles could never make a trian- gle. It has been objected, that it is more difficult to conceive the transformation of these organical particles, than even that of the animal, whose growth we are inquiring after ; and this system, therefore, attempts to explain one obscure thing by another still more obscure. But an objection, still stronger than these t has been advanced by an ingenious coun- tryman of our own ; who asserts, that these little animals, which thus appear swimming and sporting in almost every fluid we exa- mine with a microscope, are not real living particles, but some of the more opaque parts of the fluid, that are thus increased in size, and seem to have a much greater motion than they have in reality. For the motion being magnified with the object, the smallest degree of it will seem very considerable; and a being almost at rest may, by these means, be apparently put into violent action. Thus, for instance, if we look upon the sails of a windmill moving at a distance, they ap- pear to go very slow ; but, if we approach them, and thus magnify their bulk to our eye, they go round with great rapidity. A micro- scope, in the same manner, serves to bring our eye close to the object, and thus to en- large it; and not only increase the magni- tude of its parts, but of its motion. Hence, therefore, it would follow, that these organi- cal particles, that are said to constitute the bulk of living nature, are but mere optical illusions ; and the system founded on them must, like them, be illusive. These, and many other objections, have been made to this system ; which, instead of enlightening the mind, serve only to show, that too close a pursuit of nature very often leads to uncertainty. Happily, however, for b Mr. Buffon. ANIMALS. 125 mankind, the most intricate inquiries are ge- nerally the most useless. Instead, therefore, of balancing accounts between the sexes, and at- tempting to ascertain to which the business of generation most properly belongs, it will be more instructive, as well as amusing, to begin with animal nature, from its earliest retire- ments, and evanescent outlines, and pursue the incipient creature through all its changes in the womb, till it arrives into open day. The usual distinction of animals, with re- spect to their manner of generation, has been into the oviparous and viviparous kinds; or, in other words, into those that bring forth an egg, which is afterwards hatched into life, and those that bring forth their young alive and perfect. In one of these two ways all animals were supposed to have been pro- duced, and all other kinds of generation were supposed imaginary or erroneous. But later discoveries have taught us to be more cau- tious in making general conclusions, and have even induced many to doubt whether animal life may not be produced merely from putrefaction.' Indeed, the infinite number of creatures that putrid substances seem to give birth to, and the variety of little insects seen floating in liquors, by the microscope, appear to fa- vour this opinion. But, however this may be, the former method of classing animals can now by no means be admitted, as we find many animals that are produced neither from the womb, nor from the shell, but merely from cuttings ; so that to multiply life in some creatures, it is sufficient only to multiply the dissection. This being the simplest method of generation, and that in which life seems to require the smallest preparation for its exist- tence, I will begin with it, and so proceed to the two other kinds, from the meanest to the most elaborate. The earth-worm, the millepedes, the sea- worm, and many marine insects, may be mul- tiplied by being cut in pieces ; but the poly- pus is noted for its amazing fertility; and from hence it will be proper to take the de- scription. The structure of the polypus may be compared to the finger of a glove, open at one end, and closed at the other. The Bonnet Consid. p. 100. closed end represents the tail of the polypus, with which it serves to fix itself to any sub- stance it happens to be upon ; the open end may be compared to the mouth ; and, if we conceive six or eight small strings issuing from this end, we shall have a proper idea of its arms, which it can erect, lengthen, and contract, at pleasure, like the horns of a snail. This creature is very voracious, and makes use of its arms as a fisherman does of his net, to catch and entangle such little animals as happen to come within its reach. It lengthens these arms several inches, keeps them sepa- rated from each other, and thus occupies a large space in the water, in which it resides. These arms, when extended, are as fine as threads of silk, and have a most exquisite de- gree of feeling. If a small worm happens to get within the sphere of their activity, it is quickly entangled by one of these arms, and, soon after, the other arms come to its aid ; these all together shortening, the worm is drawn into the animal's mouth, and quickly devoured, colouring the body as it is swal- lowed. Thus much is necessary to be ob- served of this animal's method of living, to show that it is not of the vegetable tribe, but a real animal, performing the functions which other animals are found to perform, and en- dued with powers that many of them are des- titute of. But what is most extraordinary re- mains yet to be told ; for, if examined with a microscope, there are seen several little specks, like buds, that seem to pullulate from different parts of its body ; and these soon after appear to be young polypi, and, like the large polypus, begin to cast their little arms about for prey, in the same manner. Whatever they happen to ensnare is devour- ed, and gives a colour not only to their own bodies, but to that of the parent ; so that the same food is digested, and serves for the nourishment of both. The food of the little one passes into the large polypus, and co- lours its body ; and this, in its turn, digests, and swallows its food to pass into theirs. In this manner every polypus has a new colony sprouting from its body ; and these new ones, even while attached to the parent animal, become parents themselves, having a smaller colony also budding from them ; all, at the same time, busily employed in seeking for C* 126 A HISTORY OF their prey, and the food of any one of them serving for the nourishment, and circulating through the bodies, of all the rest. This so- ciety, however, is every hour dissolving; those newly produced are seen at intervals to leave the body of the large polypus, and become, shortly after, the head of a begin- ning colony themselves. In this manner the polypus multiplies na- turally; but one may take a much readier and shorter way to increase them, and this only by cutting them in pieces. Though cut into thousands of parts, each part still retains its vivacious qualities, and each shortly be- comes a distinct and complete polypus; whe- ther cut lengthways or crossways, it is all the same : this extraordinary creature seems a gainer by our endeavours, and multiplies by apparent destruction. The experiment haS been tried, times without number, and still attended with the same success. Here, therefore, naturalists, who have been blamed for the cruelty of their experiments upon living animals, maynow boast of their increas- ing animal life, instead of destroying it. The production of the polypus is a kind of philo- sophical generation. The famous Sir Tho- mas Brown hoped one day to be able to produce children by the same method as trees are produced : the polypus is multi- plied in this manner; and every philosopher may thus, if he please, boast of a very nume- rous, though, I should suppose, a very useless progeny. This method of generation, from cuttings, may be considered as the most simple kind, and is a strong instance of the little pains nature takes in the formation of her lower and humbler productions. As the removal of these from inanimate into animal existence is but small, there are but few preparations made for their journey. No organs of gene- ration seem provided, no womb to receive, no shell to protect them in their state of tran- sition. The little reptile is quickly fitted for all the offices of its humble sphere, and, in a very short time, arrives at the height of its contemptible perfection. The next generation is of those animals that we see produced from the egg. In this manner all birds, most fishes, and many of the insect tribes, are brought forth. An egg may be considered as a womb, detached from the body of the parent animal, in which the em- bryo is but just beginning to be formed. It maj be regarded as a kind of incomplete delivery, in which the animal is disburdened of its young before its perfect formation. Fishe* and insects, indeed, most usually commit the care of their eggs to hazard; but birds, which are more perfectly formed, are found to hatch them into maturity by the warmth of their bodies. However, any other heat, of the same temperature, would answer the end as well; for either the warmth of the sun, or of a stove, is equally efficacious in bringing the animal in the egg to perfection. In this respect, therefore, .we may consider generation from the egg as inferior to that in which the animal is brought forth alive. Nature has taken care of the viviparous ani- mal in every stage of its existence. That force which separates it from the parent, se- parates it from life ; and the embryo is shield- ed with unceasing protection till it arrives at exclusion. But it is different with the lit- tle animal in the egg ; often totally neglected by the parent, and always separable from it, every accident may retard ita growth, or even destroy its existence. Besides, art or acci- dent, also, may bring this animal to a state of perfection ; so that it can never be consi- dered as a complete work of nature, in which so much is left for accident to finish or de- stroy. But, however inferior this kind of genera- tion may be, the observation of it will afford great insight into that of nobler animals, as we can here watch the progress of the grow- ing embryo in every period of its existence, and catch it in those very moments when it first seems stealing into motion. Malpighi and Haller have been particularly indus- trious on this subject; and, with a patience almost equalling that of the sitting hen, have attended incubation in all its stages. From them, therefore, we have an amazing history of the chicken in the egg, and of its advances into complete formation. It would be methodically tedious to de- scribe those parts of the egg which are well known, and obvious ; such as its shell, its white, and its yolk; but the disposition of , these is not so apparent. Immediately under ANIMALS. 127 the shell lies that common membrane, or skin, which lines it on the inside, adhering closely to it every where, except at the broad end, where a little cavity is left, that is filled with air, which increases as the animal with- in grows larger. Under this membrane are contained two whites, though seeming to us to be only one, each wrapped up in a mem- brane of its own, one white within the other. In the midst of all is the yolk, wrapped round likewise in its own membrane. At each end of this are two ligaments, called chalazae, which are, as it were, the poles of this micro- cosm, being white dense substances, made from the membranes, and serving to keep the white and the yolk in their places. It was the opinion of Mr. Derham, that they served also for another purpose ; for a line being drawn from one ligament to the other, would not pass directly through the middle of the yolk, but rather towards one side, and would divide the yolk into two unequal parts, by which means these ligaments served to keep the smallest side of the yolk always upper- most ; and in this part he supposed the cica- tricula, or first speck of life, to reside ; which, by being uppermost, and consequently next the hen, would be thus in the warmest situ- ation. But this is rather fanciful than true, the incipient animal being found in all situa- tions, and not particularly influenced by any.* The cicatricula, which is the part where the animal first begins to show signs of life, is not unlike a vetch, or a lentil, lying on one side of the yolk, and within its mem- brane. All these contribute to the little ani- mal's convenience or support; the outer membranes and ligaments, preserve the fluids in their proper places ; the white serves as nourishment ; and the yolk, with its mem- branes, after a time, becomes a part of the animal's body. b This is the description of a hen's egg, and answers to that of all others, how large or how small soever. Previous to putting the eggs to the hen, our philosophers first examined the cicatri- cula, or little spot, already mentioned ; and which may be considered as the most im- portant part of the egg. This was found, in those that were impregnated by the cock, to Mailer. b Ibid. be large ; but in those laid without the cock, very small. It was found by the microscope, to be a kind of bag, containing a transparent liquor, in the midst of which the embryo was seen to reside. The embryo resembled a composition of little threads, which the warmth of future incubation tended to en- large, by varying and liquefying the other fluids contained within the shell, and thus pressing them either into the pores or tubes of their substance. Upon placing the eggs in a proper warmth, c either under the sun, or in a stove, after six hours the vital speck begins to dilate, like the pupil of the eye. The head of the chicken is distinctly seen, with the back-bone, some- thing resembling a tadpole, floating in its am- bient fluid, but as yet seeming to assume none of the functions of animal life. In about six hours more the little animal is seen more distinctly ; the head becomes more plainly visible, and the vertebrae of the back more easily perceivable. All these signs of prepa- ration for life are increased in six hours more : and, at the end of twenty-four hours, the ribs begin to take their places, the neck begins to lengthen, and the head to turn to one side. At this time, d also, the fluids in the egg seem to have changed place ; the yolk, which was before in the centre of the shell, ap- proaches nearer to the broad end. The wa- tery part of the white is, in some measure, evaporated through the shell, and the grosser part sinks to the small end. The little animal appears to turn towards the part of the broad end, in which a cavity has been described, and with its yolk seems to adhere to the membrane there. At the end of forty hours the great work of life seems fairly begun, and the animal plainly appears to move; the back-bone, which is of a whitish colour, thickens ; the head is turned still more on one side ; the first rudiments of the eyes begin to appear, the heart beats, and the blood begins already to circulate. The parts, however, as yet are fluid ; but, by degrees, become more and more tenacious, and harden into a kind of jelly. At the end of two days, the liquor, in which the chicken swims, seems to increase ; the head appears with two little bladders in Malpighi. Harvey. 128 A HISTORY OF the place of eyes ; the heart beats in the man- ner of every embryo where the blood does not circulate through the lungs. In about four- teen hours after this, the chicken is grown more strong; its head, however, is still bent downwards ; the veins and arteries begin to branch, in order to form the brain ; and the spinal marrow is seen stretching along the back-bone. In three days, the whole body of the chicken appears bent ; the head, with its two eye-balls, with their different humours, now distinctly appear ; and five other vesicles are seen, which soon unite to form the rudi- ments of the brain. The outlines also of the thighs and wings begin to be seen, and the body begins to gather flesh. At the end of the fourth day, the vesicles that go to form the brain approach each other; the wings and thighs appear more solid ; the whole body is covered with a jelly-like flesh; the heart, that was hitherto exposed, is now covered up with- in the body, by a very thin transparent mem- brane ; and, at the same time, the umbilical vessels, that unite the animal to the yolk, now appear to come forth from the abdomen. After the fifth and sixth days, the vessels of the brain begin to be covered over; the wings and thighs lengthen ; the belly is closed up, and tumid ; the liver is seen within it, very distinctly, not yet grown red, but of a very dusky white ; both the ventricles of the heart are discerned, as if they were two separate hearts, beating distinctly ; the whole body of the animal is covered over ; and the traces of the incipient feathers are already to be seen. The seventh day, the head appears very large; the brain is covered entirely over ; the bill begins to appear betwixt the eyes ; and the wings, the thighs, and the legs, have acquired their perfect figure.' Hitherto, however, the animal appears as if it had two bodies ; the yolk is joined to it by the umbilical vessels that come from the belly ; and is furnished with its vessels, through which the blood cir- culates, as through the rest of the body of the chicken, making a bulk greater than that of the animal itself. But towards the end of in- cubation, the umbilical vessels shorten the yolk, and with it the intestines are thrust up into the body of the chicken, by the action of Halter. the muscles of the belly ; and the two bodies are thus formed into one. During this state, all the organs are found to perform their se- cretions ; the bile is ibund to be separated, as in grown animals ; but it is fluid, transpa- rent, and without bitterness : and the chicken then also appears to have lungs. On the tenth, the muscles of the wings appear, and the fea- thers begin to push out. On the eleventh, the heart, which hitherto had appeared di- vided, begins to unite; the arteries which be- long to it join into it, like the fingers into the palm of the hand. All these appearances only come more into view, because the fluids the vessels had hitherto secreted were more transparent; but as the colour of the fluids deepen, their operations and circulations are more distinctly seen. As the animal thus, by the eleventh day completely formed, begins to gather strength, it becomes more uneasy in its situation, and exerts its animal powers with increasing force. For some time before it is able to break the shell in Avhich it is im- prisoned, it is heard to chirrup, receiving a sufficient quantity of air for this purpose, from that cavity which lies between the membrane and the shell, and which must contain air to resist the external pressure. At length, upon the twentieth day, in some birds sooner, and later in others, the inclosed animal breaks the shell within which it has been confined, with its beak ; and, by repeated efforts, at last pro- cures its enlargement. From this little history we perceive, that those parts which are most conducive to life, are the first that are begun : the head, and the back-bone, which no doubt inclose the brain, and the spinal marrow, though both are too limpid to be discerned, are the first that are seen to exist: the beating of the heart is perceived soon after : the less noble parts seem to spring from these ; the wings, the thighs, the feet, and, lastly, the bill. Whatever, therefore, the animal has double, or whatever it can live without the use of, these are latest in production : Nature first sedulously applying to the formation of the nobler organs, without which life would be of short continuance, and would be begun in vain. The resemblance between the beginning animal in the egg, and the embryo in the womb, is very striking ; and this similitude has in- ANIMALS. 129 -v* .t-~ ANIMALS. 141 has acquired the most perfect symmetry. In women, the body arrives at perfection much sooner, as they arrive at the age of maturity more early ; the muscles, and all the other parts being weaker, less compact and solid, than those of man, they require less time in coming to perfection ; and, as they are less in size, that size is sooner completed. Hence the persons of women are found to be as com- plete at twenty, as those of men are found to be at thirty. The body of a well-shaped man ought to be square ; the muscles should be expressed with boldness, and the lines of the face strongly marked. In the woman, all the mus- cles should be rounder, the lines softer, and the features more delicate. Strength and majesty belong to the man, grace and softness are the peculiar embellishments of the other sex. In both, every part of their form de- clares their sovereignty over other creatures. Man supports his body erect; his attitude is that of command ; and his face, which is turned towards the heavens, displays the dignity of his station. The image of his soul is painted in his visage ; and the. excellence of his nature penetrates through the material form in which it is enclosed. His majestic port, his sedate and resolute step, announce the nobleness of his rank. He touches the earth only with his extremity; and beholds it as if at a disdainful distance. His arms are not given him, as to other creatures, for pillars 01 support ; nor does he lose, by ren- dering them callous against the ground, that delicacy of touch which furnishes him with so many of his enjoyments. His hands are made for very different purposes; to second every intention of his will, and to perfect the gifts of Nature. When the soul is at rest, all the features of the visage seem settled in a state of pro- found tranquillity. Their proportion, their union, and their harmony, seem to mark the sweet serenity of the mind, and give a true information of what passes within. But, when the soul is excited, the human visage becomes a living picture ; where the passions are expressed with as much delicacy as energy, where every motion is designed by some correspondent feature, where every impres- sion anticipates the will, and betrays those hidden agitations, that he would often wish to conceal. It is particularly in the eyes that the pas- sions are painted ; and in which we may most readily discover their beginning. The eye seems to belong to the soul more than any other organ ; it seems to participate of all its emotions ; as well the most soft and tender, as the most tumultuous and forceful. It not only receives, but transmits them by sympathy : the observing eye of one catches the secret fire from another ; and the passion thus often becomes general. Such persons as are short-sighted labour under a particular disadvantage in this re- spect. They are, in a manner, entirely cut off from the language of the eyes ; and this gives an air of stupidity to the face, which often produces very unfavourable preposses- sions. However intelligent we find such persons to be, we can scarcely be brought back from our first prejudice, and often con- tinue in the first erroneous opinion. In this manner we are too much induced to judge of men by their physiognomy; and having, perhaps, at first, caught up our judgments prematurely, they mechanically influence us all our lives after. This extends even to the very colour, or the cut of people's clothes ; and we should, for this reason, be careful, even in such trifling particulars, since they go to make up a part of the total judgment which those we converse with may form to our advantage. The vivacity, or the languid motion of the eyes, give the strongest marks to physiog- nomy; and their colour contributes still more to enforce the expression. The different colours of the eye are the dark hazle, the light hazle, the green, the blue, and gray, the whitish gray, " and also the red." These different colours arise from the different colours of the little muscles that serve to contract the pupil; " and they are very often found to change colour with disorder and with age." The most ordinary colours are the hazle and the blue, and very often both these co- lours are found in the eyes of the same per- son. Those eyes which are called black are only of the dark hnzle, which may be easily seen upon closer inspection; however, those '2 C* ! A HISTORY OF eyes aro reckoned the most beautiful where die shade is the deepest ; and either in these, or the blue eyes, the lire, which gives its finest expression to the eye, is more distin- guishable in proportion to the darkness of the tint. For this reason, the black eyes, as they are called, have the greatest vivacity; but, probably, the blue have the most power- ful effect in beauty, as they reflect a greater variety of lights, being composed <5f more various colours. This variety, which is found in the colour of the eyes, is peculiar to man, and one or two other kinds of animals ; but, in general, the colour in any one individual is the same in all the rest. The eyes of oxen are brown ; those of sheep of a water-colour; those of goats are gray : " and it may also be, in ge- neral, remarked, that the eyes of most white animals are red ; thus the rabbit, the ferret, and, even in the human race, the white Moor, all have their eyes of a red colour." Although the eye, when put into motion, seems to be drawn on one side, yet it only moves round the centre ; by which its co- loured part moves nearer or farther from the angle of the eye-lids, or is elevated or depres- sed. The distance between the eyes is less in man than in any other animal : and in some of them it is so great, that it is impossible that they should ever view the same object with both eyes at once, unless it be very far off! " This, however, in them, is rather an advantage than an inconvenience, as they are thus able to watch round them, and guard against the dangers of their precarious situa- tion." Next to the eyes, the features, which most give a character to the face, are the eye-brows; which being, in some measure, more appa- rent than the other features, are most readi- ly distinguished at a distance. " Le Brun, in giving a painter directions, with regard to the passions, places the principal expression of the face in the eye-brows. From their ele vation and depression, most of the furious pas- sions are characterized; and such as have this feature extremely moveable, are usually known to have an expressive face. By means of these w r e can imitate all the other passions, as they are raised or depressed at command ; the rest of the features are generally fixed ; or, when put into motion, they do not obey the will : the mouth and eyes, in an actor, for instance, may, by being violently distorted, give a very different expression from what he would intend ; but the eye-brows can scarce- ly be exerted improperly ; their being raised, denotes all those passions which pride or pleasure inspire ; and their depression marks those which are the effects of contemplation and pain ; and such who have this feature, therefore, most at command, are often found to excel as actors." The eye-lashes have an effect, in giving ex- pression to the eye, particularly when long and close : they soften its glances, and im- prove its sweetness. Man and apes are the only animals that have eye-lashes both upon the upper and lower lids ; all other animals want them on the lid below. The eye-lids serve to guard the ball of the eye, and to furnish it with a proper moisture. The upper lid rises and falls ; the lower has scarcely any motion; and although JbjeLrJbeing moved depends on the will, yet it often hap- pens that the will is unable to keep them open, when sleep or fatigue oppresses the mind. In birds and amphibious quadrupeds, the lower lid alone has motion ; fishes and insects have no eye-lids whatsoever. The forehead makes a large part of the face, and a part which chiefly contributes to its beauty. It ought to be justly proportioned; neither too round nor too flat ; neither too nar- row nor too low ; and the hair should come thick upon its extremities. It is known to every body how much the hair tends to im- prove the face ; and how much the being bald serves to take away from beauty. The high- est part of the head is that which becomes bald the soonest, as well as that part which lies immediately above the temples. The hair under the temples, and at the back of the head, is very seldom known to fail, " and women are much less apt to become bald than men. Mr. Buffbn seems to think they never become bald at all ; but we have too many instances of the contrary among us, not to contradict very easily the assertion. Of all parts or appendages of the body, the hair is that which is found most different, in different climates; and often not only contributes to mark the country, but also the disposition of ANIMALS. 143 the man. It is, in general, thickest where the constitution is strongest; and more glossy, and beautiful, where the health is most per- manent. The ancients held the hair to be a sort of excrement, produced like the nails; the part next the root pushing out that im- mediately contiguous. But the moderns have found that every hair may be truly said to live, to receive nutriment, to fill and distend itself, like the other parts of the body. The roots, they observe, do not turn gray sooner than the extremities, but the whole hair changes colour at once ; and we have many instances of persons who have grown gray in one night's time.' Each hair, if viewed with a microscope, is found to consist of five or six lesser ones, all wrapped up in one common covering; it appears knotted, like some sorts of grass, and sends forth branches at the joints. It is bul- bous at the root, by which it imbibes its mois- ture from the body : and it is split at the points ; so that a single hair, at its end, re- sembles a brush. Whatever be the size or the shape of the pore, through which the hair issues, it accommodates itself to the same ; being either thick, as they are large ; small, as they are less ; round, triangular, and vari- ously formed, as the pores happen to be va- rious. The hair takes its colour from the juices flowing through it; and it is found that this colour differs in different tribes and ra- ces of people. The' Americans and the Asia- tics have their hair black, thick, straight, and shining. The inhabitants of the torrid cli- mates of Africa have it black, short, and wool- ly. The people of Scandinavia have it red, long, and curled ; and those of our own, and the neighbouring countries, are found with hair of various colours. However, it is sup- posed by many, that every man resembles in his disposition the inhabitants of those coun- tries whom he resembles in the colour and the nature of his hair ; so that the black are said, like the Asiatics, to be grave and acute ; the red, like the Gothic nations, to be choleric and bold. However this may be, the length and the strength of the hair is a general mark of a good constitution ; and, as that hair which is strongest is most commonly curled, so curl- ed hair is generally regarded among us as a Mr. BufTon says, that the hair begins to grow gray at the points ; but the fact is otherwise. b Mr. Bullun is of this opinion. Ho says, that the up- beauty. The Greeks, however, had a very different idea of beauty in this respect; and seem to have taken one of their peculiar na- tional distinctions from the length and the straightness of the hair." The nose is the most prominent feature in the face ; but, as it has scarcely any motion, and that only in the strongest passions, it ra- ther adds to the beauty than to the expres- sion of the countenance. " However, I am told, by the skilful in this branch of knowledge, that wide nostrils add a great deal to the bold and resolute air of the countenance ; and where they are narrow, though it may con- stitute beauty, it seldom improves expression." The form of the nose, and its advanced posi- tion, are peculiar to the human visage alone. Other animals, for the most part, have nos- trils, with a partition between them ; but none of them have an elevated nose. Apes them- selves have scarcely any thing else of this fea- ture but the nostrils ; the rest of the feature lying flat upon the visage, and scarcely higher than the cheek-bones. " Among all the tribes of the savage wen also, the nose is very flat ; and I have seen a Tartar who had scarcely any thing else but two holes through which to breathe." The mouth and lips, next to the eyes, are found to have the greatest expression. The passions have great power over this part of the face ; and the mouth marks its different degrees by its different forms. The organ of speech still more animates this part, and gives it more life than any other feature in the coun- tenance. The ruby colour of the lips, and the white enamel of the teeth, give it such a su- periority over every other feature, that it seems to make the principal object of our re- gards. In fact, the whole attention is fixed upon the lips of the speaker: however rapid his discourse, however various the subject, the mouth takes correspondent situations ; and deaf men have been often found to see the force of those reasonings which they could not hear, understanding every word as it was spoken. "The under jaw in man possesses a great variety of motions ; while the upper has been thought, by many, to be quite immoveable." per jaw is imiTioveahlc in all animals. However, the pat- rot is an obvious exception ; and so is man himself, as shown above. 144 A HISTORY OF However, that it moves in man, a very easy experiment will suffice to convince us. If we keep the head fixed, with any thing between our teeth, the edge of a table for instance, and then open our mouths, we shall find that both jaws recede from it at the same time; the upper jaw rises, the lower falls, and the table remains untouched between them. The upper jaw has motion as well as the under; and, what is remarkable, it has its proper muscles behind the head for thus raising and depressing it. Whenever, therefore, we eat, both jaws move at the same time, though very unequally; for the whole head moving with the upper jaw, of which it makes a part, its motions are thus less observable." In the hu- man embryo, the under jaw is very much ad- vanced before the upper. " In the adult, it hangs a good deal more backward ; and those whose upper and under row of teeth are equal- ly prominent, and strike directly against each other, are what the painters call under-hung ; and they consider this as a great defect in beauty." The under jaw in a Chinese face falls greatly more backward than with us ; and, I am told, the difference is half an inch, when the mouth is shut naturally." In instan- ces of the most violent passion, the under jaw has often an involuntary quivering motion ; and often, also, a state of languor produces another, which is that of yawning. "Every one knows how very sympathetic this kind of languid motion is ; and that for one person to yawn, is sufficient to set all the rest of the company a yawning. A ridiculous instance of this was commonly practised upon the fa- mous M'Laurin, one of the professors at Edin- burgh. He was very subject to have his jaw dislocated; so that when he opened his mouth wider than ordinary, or when he yawned, he could not shut it again. In the midst of his harangues, therefore, if any of his pupils be- gan to be tired of his lecture, he had only to gape or yawn, and the professor instantly caught the sympathetic affection ; so that he thus continued to stand speechless, with his mouth wide open, till his servant, from the next room, was called in to set his jaw again."" When the mind reflects with regret upon a Mr. Buffon says, that both jaws, in a perfect face, should be on a level : but this is denied by the best painters. some good unattained or lost, it feels an inter- nal emotion, which acting upon the diaphragm, and that upon the lungs, produces a sigh; this, when the mind is strongly affected, is re- peated ; sorrow succeeds these first emotions, and tears are often seen to follow : sobbing is the sigh still more invigorated ; and lamen- tation, or crying, proceeds from the con- tinuance of the plaintive tone of the voice, which seems to implore pity. " There is yet a silent agony, in which the mind appears to disdain all external help, and broods over its distresses with gloomy reserve. This is the most dangerous state of mind : accidents or friendship may lessen the louder kindsof grief; but all remedies for this must be had from within ; and there despair too often finds the most deadly enemy." Laughter is a sound of the voice, interrupt- ed and pursued for some continuance. The muscles of the belly, and the diaphragm, are employed in the slightest exertions ; but those of the ribs are strongly agitated in the louder; and the head sometimes is thrown backward, in order to raise them with greater ease. The smile is often an indication of kindness and good-will : it is also often used as a mark of contempt and ridicule. Blushing proceeds from different passions ; being produced by shame, anger, pride, and joy. Paleness is often also the effect of an- ger ; and almost ever attendant on fright and fear. These alterations in the colour of the countenance are entirely involuntary; all the other expressions of the passions are, in some small degree, under control; but blushing and paleness betray our secret purposes ; and we might as well attempt to stop them, as the circulation of the blood, by which they are caused. The whole head, as well as the features of the face, takes peculiar attitudes from its pas sions : it bends forward, to express humility, shame, or sorrow; it is turned to one side in languor or in pity; it is thrown with the chin forward in arrogance and pride; erect in self-conceit and obstinacy ; it is thrown back- wards in astonishment ; and combines its mo- tion to the one side and the other, to express [ b Since the publication of this work, the editor has been credibly informed, that the professor had not the defect here mentioned.] ANIMALS. 145 contempt, ridicule, anger, and resentment. "Painters, whose study leads to the contem- plation of external forms, are much more ade- quate judges of these than any naturalist can be; and it is with these a general remark, that no one passion is regularly expressed on different countenances in the same manner; but that grief often sits upon the face like joy; and pride assumes the air of passion. It would be vain, therefore, in words, to express their general effect, since they are often as various as the countenances they sit upon ; and in making this distinction nicely, lies all the skill of the physiognomist. In being able to distinguish what part of the face is marked by nature, and what by the mind ; what part had been originally formed, and what is made by habit, constitutes this science, upon which the ancients so much valued themselves, and which we at present so little regard. Some, however, of the most acute men among us, have paid great attention to this art ; and, by long practice, have been able to give some character of every person whose face they ex- amined. Montaigne is well known to have disliked those men who shut one eye in look- ing upon any object ; and Fielding asserts, that he never knew a person with a steady glavering smile, but he found him a rogue. However, most of these observations, tending to a discovery of the mind by the face, are merely capricious ; and Nature has kindly hid our hearts from each other, to keep us in good humour with our fellow-creatures." The parts of the head which give the least expression to the face, are the ears ; and they are generally found hidden under the hair. These, which are immoveable, and make so small an appearance in man, are very distin- guishing features in quadrupeds. They serve in them as the principal marks of the passions; the ears discover their joys or their terrors, with tolerable pecision ; and denote all their internal agitations. The smallest ears, in men, are said to be most beautiful ; but the largest are found the best for hearing. There are some savage nations who bore their ears, and so draw that part down, that the tips of the ears are seen to rest upon their shoulders. The strange variety of the different customs of men, appears still more extravagant in their manner of wearing their beards. Some, and among others the Turks, cut the hair off* their heads, and let their beards grow. The Eu- ropeans, on the contrary, shave their beards, and wear their hair. The Negroes shave their heads in figures at one time, in stars af another, in the manner of friars ; and still morecommonly in alternate stripes ; and their little boys are shaved in the same manner. The Talapoins, of Siam, shave the heads and the eye-brows of such children as are com- mitted to their care. Every nation seems to have entertained different prejudices, at dif- ferent times, in favour of one part or another of the beard. Some have admired the hair upon the cheeks on each side, as we see with some low-bred men among ourselves, who want to be fine. Some like the hair lower down ; some choose it curled ; and others like it straight. " Some have cut it into a peak ; and others shave all but the whisker. This particular part of the beard was highly prized among the Spaniards ; till of late, a man without whiskers was considered as un- fit for company ; and where Nature had de- nied them, Art took care to supply the defi- ciency. We are told of a Spanish 'general who, when he borrowed a large sura of money from the Venetians, pawned his whisker, which he afterwards took proper care to re- lease. Kingson assures us, that a considera- ble part of the religion of the Tartars con- sists in the management of their whiskers; and that they waged a long and bloody war with the Persians, declaring them infidels, merely because they would not give their whiskers the orthodox cut. The kings of Persia car- ried the care of their beards to a ridiculous excess, when they chose to wear them mat- ted with gold thread : and even the kings ol France, of the first races, had them knotted and buttoned with gold. But of all nations, the Americans take the greatest pains in cut ting their hair, and plucking their beards. The under part of the beard, and all but the whisker, they take care to pluck up by the roots, so that many have supposed them to have no hair naturally growing on that part : and even Linnaeus has fallen into that mistake. Their hair is also cut into bands; and no small care employed in adjusting the whisker. In fact, we have a very wrong idea of savage finery ; and are apt to suppose that, like the 146 A HISTORY OF beasts of the forest, they rise, and are dres- sed with a shake : but the reverse is true ; for no birth-night beauty takes more time or pains in the adorning her person than they. I remember, when the Cherokee kings were over here, that I have waited for three hours during the time they were dressing. They never would venture to make their appear- ance till they had gone through the tedious ceremonies of the toilet : they had their boxes of oil and ochre, their fat. and their perfumes, like the most effeminate beau, and generally took up four hours in dressing, before they considered themselves as fit to he seen. We must not, therefore, consider a delicacy in point of dress, as a mark of refinement, since savages are much more difficult in this par- ticular, than the most fashionable or tawdry European. The more barbarous the people, the fonder of finery. In Europe, the lustre of jewels, and the splendour of the most brilliant colours, are generally given up to women, or to the weakest part of the other sex, who are willing to be contemptibly fine : but in Asia, these trifling fineries are eagerly sought after by every condition of men ; and, as the pro- verb has it, we find the richest jewels in an jEthiop's ear. The passion for glittering or- naments, is still stronger among the absolute barbarians, who often exchange their whole stock of provisions, and whatever else they happen to be possessed of, with our seamen, for a glass-bead, or a looking-glass." Although fashions have arisen in different countries from fancy and caprice, these, when they become general, deserve examination. Mankind have always considered it as a mat- ter of moment, and they will ever continue desirous of drawing the attention of each other, by such ornaments as mark the riches, the power, or the courage of the wearer. The value of those shining stones which have at all times been considered as precious or- naments,is entirely founded upon their scarce- ness or their brilliancy. It is the same like- wise with respect to those shining metals, the weight of which is so little regarded, when spread over our clothes. These ornaments are rather designed to draw the attention of others, than to add to any enjoyments of our own ; and few there are that these ornaments will not serve to dazzle, and who can coolly distinguish between the metal and the man. All things rare and brilliant will, therefore, ever continue to be fashionable, while men derive greater advantage from opulence than virtue ; while the means of appearing con- siderable are more easily acquired, than the title to be considered. The first impression we generally make, arises from our dress ; and this varies, in conformity to our inclina- tions, and the manner in which we desire to be considered. The modest man, or he who would wish to be thought so, desires to show the simplicity of his mind by the plainness of his dress ; the vain man, on the contrary, takes a pleasure in displaying his superiority, " and is willing to incur the spectator's dis- like, so he does but excite his attention." Another point of view which men have in dressing, is to increase the size of their figure ; and to take up more room in the world than Nature seems to have allotted them. We de- sire to swell out our clothes by the stiffness of art, and raise our heels, while we add to the largeness of our heads. How bulky so- ever our dress may be, our vanities are still more bulky. The largeness of the doctor's wig arises from the same pride with the small- ness of the beau's queue. Both want to have the size of their understanding measured by the size of their heads. There are some modes that seem to have a more reasonable origin, which is to hide or to lessen the defects of Nature. To take men altogether, there are many more deformed and plain, than beautiful and shapely. The former, as being the most numerous, give law to fashion ; and their laws are generally such as are made in their own favour. The wo- men begin to colour their cheeks with red, when the natural roses are faded; and the younger are obliged to submit, though not compelled by the same necessity. In all parts of the world, this custom prevails more or less; and powdering and frizzing the hair, though not so general, seems to have arisen from a similar control. But leaving the draperies of the human pic- ture, let us return to the figure, unadorned by art. Man's head, whether considered exter- nally or internally, is differently formed from that of all other animals, the monkey-kind only excepted, in which there is a striking ANIMALS. 147 similitude. There fire some differences, how- ever, which we shall take notice of in ano- ther place. The bodies of all quadruped ani- mals are covered with hair ; but the head of man seems the part most adorned ; and that more abundantly than in any other animal. There is a very great variety in the teeth of all animals ; some have them above and below ; others have them in the under jaw only ; in some they stand separate from each other ; while in some they are continued and united. The palate of some fishes is nothing else but a bony plate studded with points, which perform the offices of teeth. All these substances, in every animal, derive their ori- gin from the nerves ; the substance of the nerves hardens by being exposed to the air; and the nerves that terminate in the mouth, being thus exposed, acquire a bony solidity. In this manner, the teeth and nails are formed in man ; and in this manner, also, the beak, the hoofs, the horns, and the talons, of other animals, are found to be produced. The neck supports the head, and unites it to the body. This part is much more con- siderable in the generality of quadrupeds, than in man. But fishes, and other animals that want lungs similar to ours, have no neck whatsoever. Birds, in general, have the neck longer than any other kind of animals : those of them, which have short claws, have also short necks ; those, on the contrary, that have them long, are found to have the neck in pro- portion. " In men, there is a lump upon the wind-pipe, formed by the thyroid cartilage, which is not to be seen in women ; an Arabi- an fable says, that this is a part of the origi- nal apple, that has stuck in the man's throat by the way, but that the woman swallowed her part of it down." The human breast is outwardly formed in a very different manner from that of other animals. It is larger in proportion to the size of the body ; and none but man, and such ani- mals as make use of their fore feet as hands, such as monkeys, bats, and squirrels, and such quadrupeds as climb trees, are found to have those bones called the clavicles, or, as we usually term them, the collar-bones." * Mr. Buffon says, that none but monkeys have them ; hut this is an oversight. The breasts in women are larger than in men; however, they seem formed in the same man- ner; and, sometimes, milk is found in the breasts of men, as well as in those of women. Among animals, there is a great variety in this part of the body. The teats of some, as in the ape and the elephant, are like those of men, being but two, and placed on each side of the breast. The teats of the bear amount to four. The sheep has but two, placed between the hinder legs. Other animals, such as the bitch and the sow, have them all along the belly ; and, as they produce many young, they have a great many teats for their support. The form also of the teats varies in different animals ; and, in the same animal, at different ages. The bosom in females, seems to unite all our ideas of beauty, where the outline is continually changing, and the gradations are soft and regular. " The graceful fall of the shoulders, both in man and woman, constitute no small part of beauty. In apes, though otherwise made like us, the shoulders are high, and drawn up on each side towards the ears. In man they fall by a gentle declivity ; and the more so, in proportion to the beauty of his form. In fact, being high-shouldered, is not without rea- son considered as a deformity, for we find very sickly persons are always so ; and people, when dying, are ever seen with their shoul- ders drawn up in a surprising manner. The muscles that serve to raise the ribs, mostly rise near the shoulders : and the higher we raise the shoulders, we the more easily raise the ribs likewise. It happens, therefore, in the sickly and the dying, who do not breathe without labour, that to raise the ribs, they are obliged to call in the assistance of the shoul- ders; and thus their bodies assume, from ha- bit, that form which they are so frequently obliged to assume. Women with child also, are usually seen to be high-shouldered ; for the weight of the inferior parts drawing down the ribs, they are obliged to use every effort to elevate them, and thus they raise the shoul- ders of course. During pregnancy, also, the shape, not only of the shoulders, but also of the breast, and even the features of the face, are greatly altered : for the whole upper fore- part of the body is covered with a broad thin skin, called the myoides; which being, at 148 A HISTORY OF that time, drawn down, it also draws down with it the skin, and, consequently, the fea- tures of the face. By these means the visage takes a particular form ; the lower eye-lids, and the corners of the mouth, are drawn down- wards ; so that the eyes are enlarged, and the mouth lengthened ; and women, in these cir- cumstances, are said, by the midwives, to be all mouth and eyes." The arms of men but very little resemble the fore feet of quadrupeds, and much less the wings of birds. The ape is the only ani- mal that is possessed of hands and arms ; but these are much more rudely fashioned, and with less exact proportion, than in men ; " the thumb not being so well opposed to the rest of the lingers, in their hands, as in ours." The form of the back is not much different in mail from that of other quadruped animals, only that the reins are more muscular in him, and stronger. The buttock, however, in man, is different from that of all other animals whatsoever. What goes by that name, in other creatures, is only the upper part of the thigh ; man being the only animal that sup- ports himself perfectly erect, the largeness of this part is owing to the peculiarity of his position. Man's feet, also, are different from those of all other animals, those even of apes not ex- cepted. The foot of the ape is rather a kind of awkward hand ; its toes, or rather fingers, are long, and that of the middle longest of all. This foot also wants the heel, as in man ; the sole is narrower, and less adapted to main- tain the equilibrium of the body in walking, dancing, or running. The nails are less in man than in any other animal. If they were much longer than the extremities of the fingers, they would rather be prejudicial than serviceable, and obstruct the management of the hand. Such savages as let them grow long, make use of them in flaying animals, in tearing their flesh, and such like purposes ; however, though their nails are considerably larger than ours, they are |jy no means to be compared to the hoofs or the claws of other animals. "They may sometimes be seen longer, indeed, than the claws of any animal whatsoever ; as we learn that the nails of some of the learned men in China are longer than their fingers. But these want that solidity which might give force to their exertions ; and could never, in a state of nature, have served them for an- noyance or defence." There is little known exactly with regard to the proportion of the human figure ; and the beauty of the best statues is better con- ceived by observing than by measuring them. The statues of antiquity, which were at first copied after the human form, are now become the models of it; nor is there one man fouiid whose person approaches to those inimitable performances, that have thus, in one figure, united the perfections of many. It is suffici- ent to say that, from being at first models, they are now become originals ; and are used to correct the deviations in that form from whence they were taken. I will not, how- ever, pretend to give the proportions of the human body, as taken from these, there being nothing more arbitrary, and which good pain- ters themselves so much contemn. Some, for instance, who have studied after these, divide the body into ten times the length of the face, and others into eight. Some pretend to tell us, that there is a similitude of proportion in different parts of the body. Thus, that the hand is the length of the face ; the thumb the length of the nose ; the space between the eyes is the breadth of an eye ; that the breadth of the thigh, at thickest, is double that of the thickest part of the leg, and treble the small- est ; that the arms extended, are as long as the figure is high ; that the legs and thighs are half the length of the figure. All this, how- ever, is extremely arbitrary; and the excel- lence of a shape, or the beauty of a statue, results from the attitude and position of the whole, rather than any established measure- ments, begun without experience, and adopt- ed by caprice. In general, it may be re- marked, that the proportions alter in every age, and are obviously different in the two sexes. In women, the shoulders are narrow- er, and the neck proportionably longer, than in men. The hips also are considerably lar- ger, and the thighs much shorter, than in men. These proportions, however, vary greatly at different ages. In infancy, the upper parts of the body are much larger than the lower ; the legs and thighs do not constitute any thing like half the height of the wkole figure : in ANIMALS. 1-19 proportion as the child increases in age, the inferior parts are found to lengthen; so that the body is not equally divided until it has acquired its full growth. The size of men varies considerably. Men are said to be tall who are from five feet eight inches to six feet high. The middle stature is from five feet five to five feet eight : and those are said to be of small stature who fall under these measures. " However, it ought to be remarked, that the same person is al- ways taller when he arises in the morning, than upon going to bed at night ; and some- times there is an inch difference; and I have seen more. Few persons are sensible of this remarkable variation; and I am told, it was first perceived, in England, by a recruiting officer. He often found that those men whom he had enlisted for soldiers, and answered to the appointed standard at one time, fell short of it when they came to be measured before the colonel, at the head-quarters. This di- minution in their size proceeded from the dif- ferent times of the day, and the different states of the body, when they happened to be mea- sured. If, as was said, they were measured in the morning, after the night's refreshment, they were found to be commonly half an inch, and very often a whole inch, taller than if measured after the fatigues of the day ; if they were measured when fresh in the country, and before a long fatiguing march to the re- giment, they were found to be an inch taller than when they arrived at their journey's end. All this is now well known among those who recruit for the army, and the reason of this difference of stature is obvious. Between all the joints of the back-bone, which is compo- sed of several pieces, there is a glutinous li- quor deposited, which serves, like oil in a , machine, to give the parts an easy play upon each other. This lubricating liquor, or sy- novia, as the anatomists call it, is poured in during the season of repose, and is consumed by exercise and employment; so that in a body, after hard labour, there is scarce any of it remaining; but all the joints grow stiff, and their motion becomes hard and painful. It is from hence, therefore, that the body di- minishes in stature. For this moisture being drained away from between the numerous joints of the back-bone, they lie closer upon ! each other; and their whole length is thus very sensibly diminished ; but sleep, by re- storing the lluid again, swells the spaces be- tween the joints, and the whole is extended to its former dimensions. " As the human body is thus often found to differ from itself in size, so it is found to dif- fer in its weight also; and the same person, without any apparent cause, is found to be heavier at one time than another. If, after having eaten a hearty dinner, or having drunk hard, the person should find himself thus hea- vier, it would appear no way extraordinary ; but the fact is, the body is very often Ibuud heavier some hours after eating a hearty meal than immediately succeeding it. If, for in- stance, a person, fatigued by a day's hard la- bour, should eat a plentiful supper, and then get himself weighed upon going to bed; after sleeping soundly, if he is again weighed, he will find himself considerably .heavier than before ; and this difference is often found to amount to a pound, or sometimes to a pound and a half. From whence his adventitious weight is derived is not easy to conceive; the body, during the whole night, appears ra- ther plentifully perspiring than imbibing any fluid, rather losing than gaining moisture : however, we have no reason to doubt, but that either by the lungs, or perhaps, by a pecu- liar set of pores, it is all this time inhaling a quantity of fluid, which thus increases, the weight of the whole body, upon being weigh- ed the next morning." 11 Although the human body is externally more delicate than any of the quadruped kind, it is, notwithstanding, extremely muscular; and, perhaps, for its size, stronger than that of any other animal. If we should offer to compare the strength of the lion with that of man, we should consider that the claws of this animal, give us a false idea of its power ; we ascribe to its force what is only the effects of its arms. Those which man has received from Nature are not offensive ; happy had Art never furnished him with any more terrible than those which arm the paws of the lion ! a From the experiment also, the learned may gather upon what a weak foundation the whole doctrine of'Sanc- torian perspiration is built: but this disquisition more pro- perly belongs to medicine than natural history. 2F* A HISTORY OF But there is another manner' 1 of comparing the strength of man with that of other ani- mals ; namely, by the weights which either can carry. We are assured that the porters of Constantinople carry burdens of nine hun- dred pounds weight. Mr. Desaguliers tells us of a man, who by distributing weights in such a manner, as that every part of his body bore its share, was thus able to raise a weight of two thousand pounds. A horse, which is about seven times our bulk, would be thus able to raise a weight of fourteen thousand pounds, if its strength were in the same proportion. 11 " But, the truth is, a horse will not carry upon its back above a weight of two or three hun- dred pounds ; while a man, of confessedly in- ferior strength, is thus able to support two thousand. Whence comes this seeming su- periority ? The answer is obvious. Because the load upon the man's shoulders is placed to the greatest advantage ; while, upon the horse's back, it is placed at the greatest disadvantage. Let us suppose, for a moment, the man stand- ing as upright as possible, under the great load above mentioned. It is obvious .that all the bones of his body may be compared to a pil- lar supporting a building, and that his muscles have scarce any share in this dangerous duty. However, they are not entirely inactive; as man, let him stand never so upright, will have some bending in different parts of his body. The muscles, therefore, give the bones some assistance, and that with the greatest possible advantage. In this manner, a man has been found to support two thousand weight ; but may be capable of supporting a still greater. The manner in which this is done, is by strap- ping the load round the shoulders of the per- son who is to bear it, by a machine something like that by which milk vessels or water- buckets are carried. The load being thus placed on a scaffold, on each side, contrived for that purpose, and the man standing erect in the midst, all parts of the scaffold, except that where the man stands, arc made to sink ; and thus the man maintaining his position, the load, whatever it is, becomes suspended, and the column of his bones may be fairly said to support it. If, however, he should but ever so little give way, he must inevitably drop ; * a Mr. Buflbn calls it a better manner; but this is not the case. and no power of his can raise the weights again. But the case is very different with re- gard to a load laid upon a horse. The column of the bones there lies a different way ; and a weight of five hundred pounds, as I am told, would break the back of the strongest horse that could be found. The great force of a horse, and other quadrupeds, is exerted when the load is in such a position as that the column of the bones can be properly applied, which is lengthwise. When, therefore, we are to estimate the comparative strength of a horse, we are not to try what he can carry, but what he can draw ; and, in this case, his ama- zing superiority over man is easily discerned ; for one horse can draw a load that ten men cannot move. And, in some cases, it happens that a draft-horse draws the better for being somewhat loaded ; for, as the peasants say, the load upon the back keeps him the better to the ground." There is still another way of estimating hu- man strength, by the perseverance and agility of our motions. Men, who are exercised in running, outstrip horses ; or, at least, hold their speed for a longer continuance. In a journey, also, a man will walk down a horse ; and, after they have both continued to proceed for several days, the horse will be quite tired, and the man will be fresher than in the begin- ning. The king's messengers of Ispahan, who are runners by profession, go thirty-six leagues in fourteen hours. Travellers assure us, that the Hottentots outstrip lions in the chase ; and that the savages, who hunt the elk, pursue with such speed, that they at last tire down and take it. We are told many very surprising things of the great swiftness of the savages, and of the long journeys they undertake, on foot, through the most craggy mountains, where there are no paths to direct, nor houses to entertain them. They are said to perform a journey of twelve hundred leagues in less than six weeks. " But notwithstanding what tra- vellers report of this matter, I have been as- sured, from many of our officers and soldiers, who compared their own swiftness with that of the native Americans, during the last war, that although the savages held out, and, as the phrase is, had better bottoms, yet, for a b Mr. Buflbn carries this subject no farther ; and thus far, without explanation, it is erroneous. OF ANIMALS. 151 spurt, the Englishmen were more nimble and speedy." Nevertheless, in general, civilized man is ignorant of his own powers : he is ignorant how much he loses by effeminacy ; and what might be acquired by habit and exercise. Here and there, indeed, men are found among us of extraordinary strength; but that strength, for want of opportunity, is seldom called into exertion. " Among the ancients it was a qua- lity of nuch greater use than at present ; as in wur, the same man that had strength sufficient to carry the heaviest armour, had strength sufficient also to strike the most fatal blow. In this case, his strength was at once his pro- tection and his power. We ought not to be surprised, therefore, when we hear of one man terrible to an army, and irresistible in his ca- reer, as we find some generals represented in ancient history. But we may be very certain that this prowess was exaggerated by flattery, and exalted by terror. An age of ignorance is ever an age of wonder. At such times, mankind, having no just ideas of the human powers, are willing rather to represent what they wish, than what they know ; and exalt human strength, to fill up the whole sphere of their limited conceptions. Great strength is an accidental thing ; two or three in a coun- try may possess it ; and these may have a claim to heroism. But what may lead us to doubt of the veracity of these accounts is, that the heroes of antiquity are represented as the sons of heroes ; their amazing strength is de- livered down from father to son ; and this we know to be contrary to the course of nature. Strength is not hereditary, although titles are : and I am very much induced to believe, that this great tribe of heroes, who are all repre- sented as the descendants of heroes, are more obliged to their titles than to their strength, for their characters. With regard to the shining characters in Homer, they are all re- presented as princes, and as the sons of princes ; while we are told of scarce any share of prowess in the meaner men of the army ; who are only brought into the field for these to pro- tect, or to slaughter. But nothing can be more unlikely than that those men, who were bred in the luxury of courts, should be strong ; while the whole body of the people, who re- ceived a plainer and simpler education, should be comparatively weak. Nothing can be more contrary to the general laws of nature, than that all the sons of heroes should thus in- herit not only the kingdoms, but the strength of their forefathers; and we may conclude, that they owe the greatest share of their im- puted strength rather to the dignity of their sta- tions than the force of their arms ; and, like all fortunate princes, their flatterers happened to be believed. In later ages, indeed, we have some accounts of amazing strength, which we can have no reason to doubt of. But in these, nature is found to pursue her ordinary course ; and we find their strength accidental. We find these strong men among the lowest of the people, and gradually rising into notice, as this superiority had more opportunity of being seen. Of this number was the Roman tribune, who went by the name of the second Achilles : who, with his own hand, is said to have killed, at different times, three hundred of the enemy; and when treacherously set upon, by twenty- five of his own countrymen, although then past his sixtieth year, killed fourteen of them before he was slain. Of this number was Milo, who, when he stood upright, could not be forced out of his place. Pliny tells us of one Athanatus, who walked across the stage at Rome, loaded with a breastplate weighing five hundred pounds, and buskins of the same weight. But of all the prodigies of strength, of whom we have any accounts in Roman history, Maximin, the emperor, is to be reckon- ed the foremost. Whatever we are told rela- tive to him is well attested ; his character was too exalted not to be thoroughly known ; and that very strength, for which he was celebrated, at last procured him no less a reward than the empire of the world. Maximin was above nine feet in height, and the best proportioned man in the whole empire. He was by birth a Thracian; and, from being a simple herds- man, rose through the gradations of office, until he came to be emperor of Rome. The first opportunity he had of exerting hisstrength, was in the presence of all the citizens, in the theatre, where he overthrew twelve of the strongest men in wrestling, and outstrip! two of the fleetest horses in running, all in one day. He could draw a chariot loaden, that two strong hordes could not move : he could break a horse's jaw with a blow of his fist, and its thigh with a kick. In war he was always foremost and invincible : happy had it been 152 A HISTORY OF for him and his subjects if, from being formi- dable to his enemies, he had not brconic still more so to his subjects ; he reigned, for some time, with all the world his enemy ; all man- kind wishing him dead, yet none daring to strike the blow. As if fortune had resolved that through life he should continue uncon- querable, he was killed at last by his own sol- diers while he was sleeping. We have many other instances, in later ages, of very great strength, and not fewer of amazing swiftness : but these, .merely corporeal perfections, are now considered as of small advantage, either in war or in peace. The invention of gun- powder has, in some measure, levelled all force to one standard ; and has wrought a total change in martial education through all parts of the world. In peace also the inven- tion of new machines every day, and the ap- plication of the strength of the lower animals to the purposes of life, have rendered human strength less valuable. The boast of corporeal force is, therefore, consigned to savage nations, where those arts not being introduced, it may still be needful ; but, in more polite countries, few will be proud of that strength which other animals can be taught to exert to as useful purposes as they. " If we compare the largeness and thickness of our muscles with those of any other animal, we shall find that, in this respect, we have the advantage ; and if strength, or swiftness, de- pended upon the quantity of muscular flesh nlonc, I believe that, in this respect, we should be more active and powerful than any other. But this is not the case ; a great deal more than the size of the muscles goes to constitute activity or force ; and it is not he who has the thiekestlegs that can make the best use of them. Those, therefore, who have written elaborate treatises on muscular force, and have estimated the strength of animals by the thickness of their muscles, have been employed to very little purpose. It is in general observed, that thin and raw-boned men are always stronger and more powerful, than such as are seem- ingly more muscular ; as in the former all the parts have better room for their ex- ertions." Women want much of the strength of men ; and, in some countries, the stronger sex have availed themselves of this superiority, in cruelly and tyrannically enslaving those who were made with equal pretensions to a share in all the advantages life can bestow. Savage na- tions oblige their women to a life of continual labour ; upon them rest all the drudgeries of domestic duty ; while the husband, indolently reclined in his hammock, is first served from the fruits of her industry. From this negli- gent situation he is seldom roused, except by the calls of appetite, when it is necessary, either by fishing or hunting, to make a variety in his entertainments. A savage has no idea of taking pleasure in exercise ; he is surprised to see an European walk forward for his amuse- ment, and then return back again. As for his part, he could be contented to remain for ever in the same situation, perfectly satisfied with sensual pleasures and undisturbed repose. The women of these countries are the greatest slaves upon earth : sensible of their weakness ; and unable to resist, they are obliged to suffer those hardships which are naturally inflicted by such as have been taught that nothing but corporeal force ought to give pre-eminence. It is not, therefore, till after some degree of refinement, that women are treated with lenity ; and not till the highest degree of po- liteness, that they are permitted to share in all the privileges of man. The first impulse of savage nature is to confirm their slavery ; the next of half barbarous nations, is to appropriate their beauty ; and that of the perfectly polite, to engage their affections. In civilized coun- tries, therefore, women have united the force of modesty to the power of their natural charms; and thus obtain that superiority over the mind, which they are unable to extort by their strength. ANIMALS. 153 CHAPTER XXVIII. OF SLEEP AND HUNGER. AS man, in all the privileges he enjoys, and the powers he is invested with, has a superi- ority over all other animals, so, in his necessities, he seems inferior to the meanest of them all. Nature has brought him into life with a greater variety of wants and infir siities than the rest of her creatures, unarmed in the midst of ene- mies. The lion has natural arms; th:- l>< ar natural clothing ; but man is destitute of all such advantages ; and, from the superiority of his mind alone, he is to supply the deficiency. The number of his wants, however, were merely given, in order to multiply the number of his enjoyments ; since the possibility of be- ing deprived of any good, teaches him the value of its possession. Were .HMD born with those advantages which he learns to possess by in- clu*try, he would very probably enjoy them with a blunter relish ; it is by being naked, that he knows the value of a covering ; it is by being exposed to the weather, that he learns the comforts of an habitation. Every want thus becomes a means of pleasure, in the re- dressing; and the animal that has most desires, may be said to be capable of the greatest variety of happiness. Beside the thousand imaginary wants pecu- liar to man, there are two, which he has in common with all other animals ; and which he feels in a more necessary manner than they. These are the wants of sleep and hunger. Every animal that we are acquainted with, seems to endure the want of these with much less injury to health than man ; and some are j most surprisingly patient in sustaining both. The little domestic animals that we keep about us, may often set a lesson of calm resignation, in supporting want and watchfulness, to the boasted philosopher. They receive their pit- tance at uncertain intervals, and wait its coming j with cheerful expectation. We have instances j of the dog and the cat living in this manner, without food, for several days ; and yet still ! preserving their attachment to the tyrant that oppresses them ; still ready to exert their little services for his amusement or defence. But the patience of these is nothing, to what the animals of the forest endure. As these mostly live upon accidental carnage, so they are often known to remain without food for several weeks together. Nature, kindly solicitous for their support, has also contracted their sto- machs, to suit them for their precarious way of living: and kindly, while it abridges the banquet, lessens the necessity of providing for it. But the meaner tribes of animals are made still more capable of sustaining life without food, many of them remaining in a state of torpid indifference, till their prey approaches, when j they jump upon and seize it. In this manner the snake, or the spider, continue, for several months together, to subsist upon a single meal ; and some of the butterfly kinds live upon little or nothing. But it is very different with man : his wants daily make their importunate de- mands ; and it is known, that he cannot con- tinue to live many days without eating, drink- ing, and sleeping. Hunger is a much more powerful enemy to man than watchfulness, and kills him much sooner. It may be considered as a disorder that food removes ; and that would quickly be fatal, without its proper antidote. In fact, it is so terrible to man, that to avoid it he even en- counters certain death ; and, rather than en- dure its tortures, exchanges them for immediate destruction. However, by what I have been told, it is much more dreadful in its approaches, than in its continuance ; and the pains of a famishing wretch decrease, as his strength di- minishes. In the beginning, the desire of food ! is dreadful indeed, as we know by experience, for there are few who have not in some degree, felt its approaches. But, after the first or second day, its tortures become less terrible, and a total insensibility at length comes kindly in to the poor wretch's assistance. I have talked with the captain of a ship, who was one of six that endured it in its extremities ; and who was the only person that had not lost his 154 A HISTORY OF senses, when they received accidental relief. He assured me, his pains, at first, were so great, as to be often tempted to eat a part of one of the men who died ; and which the rest of his crew actually for some time lived upon : he said, that during the continuance of this pa- roxysm, he found his pains insupportable ; and was desirous, at one time, of anticipating that death which he thought inevitable : but his pains, he said, gradually decreased after the sixth day, (for they had water in the ship, which kept them alive so long,) and then he was in a state rather of languor than desire ; nor did he much wish for food, except when he saw others eating ; and that for a while revived his appetite, though with diminished importunity. The latter part of the time, when his health was almost destroyed, a thou- sand strange images rose upon his mind ; and every one of his senses began to bring him wrong information. The most fragrant per- fumes appeared to him to have a foetid smell; and every thing he looked at took a greenish hue, and sometimes a yellow. When he was presented with food by the ship's company that took him and his men up, four of whom died shortly after, he could not help looking upon it with loathing, instead of desire ; and it was not till after four days, that his stomach was brought to its natural tone, when the violence of his appetite returned, with a sort of canine eagerness. Thus dreadful are the effects of hunger ; and yet when we come to assign the cause that produces them, we find the subject involved in doubt and intricacy. This longing eagerness is, no doubt, given for a very obvious purpose ; that of replenishing the body, wasted by fatigue and perspiration. Were not men stimulated by such a pressing monitor, they might be apt to pursue other amusements, with a persever- ance beyond their power; and forget the useful hours of refreshment, in those more tempting ones of pleasure. But hunger makes a demand that will not be refused ; and, indeed, the generality of mankind seldom await the call. Hunger has been supposed by some to arise from the rubbing of the coats of the stomach against each other, without having any inter- vening substance to prevent their painful attri- tion. Others have imagined, that its juices, wanting their necessary supply, turn acrid, or, as some say, pungent ; and thus fret its internal coats, so as to produce a train of the most uneasy sensations. Boerhaave, who establish- ed his reputation in physic, by uniting the conjectures of all thoae that preceded him, ascribes hunger to the united effect of both these causes; and asserts, that the pungency of the gastric juices, and the attrition of its coats against each other, cause those pains, which nothing but food can remove. These juices continuing still to be separated in the stomach, and every moment becoming more acrid, mix with the blood, and infect the cir- culation : the circulation being thus contami- nated, becomes weaker, and more contracted ; and the whole nervous frame sympathizing, an hectic fever, and sometimes madness, is pro- duced ; in which state the faint wretch expires. In this manner, the man who dies of hunger, may be said to be poisoned by the juices of his own body ; and is destroyed less by the want of nourishment, than by the vitiated qualities of that which he had already taken. However this may be, we have but few in- stances of men dying, except at sea, of abso- lute hunger. The decline of those unhappy creatures who are destitute of food, at land, bt-ing more slow and unperceived. These, from often being in need, and as often receiv- ing an accidental supply, pass their lives be- tween surfeiting and repining ; and UK ir con- stitution is impaired by insensible degrees. Man is unfit for a state of precarious expecta- tion. That share of provident precaution which incites him to lay up stores for a distant day, becomes his torment, when totally unpro- vided against an immediate call. The lower race of animals, when satisfied, for the instant moment, are perfectly happy : but it is other- wise with man ; his mind anticipates distress, and feels the pangs of want even before it ar- rests him. Thus the mind being continually harassed by the situation, it at length influen- ces the constitution, and unfits it for all its func- tions. Some cruel disorder, but no way like hunger, seizes the unhappy sufferer ; so that almost all those men who have thus long lived by chance, and whose every day may be con- sidered as an happy escape from famine, are known at last to die in reality of a disorder caused by hunger ; but which, in the common language, is often called a broken heart. Some of these I have known myself, when very lit- tle able to relieve them : and I have been told, OF ANIMALS. 155 by a very active and worthy magistrate, that the number of such as die in London for want, is much greater than one would imagine I think he talked of two thousand in a year! But how numerous soever those who die of hunger may be, many times greater, on the other hand, are the number of those who die by repletion. It is not the province of the pre- sent page to speculate, with the physician, upon the danger of surfeits ; or, with the moralist, upon the nauseousness of gluttony : it will only be proper to observe, that as nothing is so prejudicial to health as hunger by constraint, so nothing is more beneficial to the constitu- tion than voluntary abstinence. It was not without reason that religion enjoined this duty ; since it answered the double purpose of re- storing the health oppressed by luxury, and di- minished the consumption of provisions, so that a part might come to the poor. It should be the business of the legislature, therefore, to enforce this divine precept ; and thus, by re- straining one part of mankind in the use of their superfluities, to consult for the benefit of those who want the necessaries of life. The injunctions for abstinence are strict over the whole Continent ; ajid where rigorously obser- ved even among ourselves, for a long time af- ter the Reformation. Queen Elizabeth, by giving her commands upon this head the air of a political injunction, lessened, in a great mea- sure, and in my opinion very unwisely, the re- ligious force of the obligation. She enjoined that her subjects should fast from flesh on Fri- days and Saturdays ; but at the same time de- clared, that this was not commanded from mo- tives of religion, as if there were any differences in meats, but merely to favour the consumpti- on offish, and thus to multiply the number of mariners ; and also to spare the stock of sheep, which might be more beneficial in another way. In this manner the injunction defeated its own force ; and this most salutary law became no longer binding, when it was supposed to come purely from man. How far it may be enjoin- ed in the Scriptures, I will not take upon me to say ; but this may be asserted, that if the utmost benefit to the individual, and the most extensive advantage to society, serve to mark any institution as of Heaven, this of abstinence may be reckoned among the foremost. Were we to give an history of the various benefits that have arisen from this command, and how conducive it has been to long life, the instances would fatigue with their multiplicity. It is surprising to what a great age the primi- tive Christians of the East, who retired from persecution in the deserts of Arabia, continued to live, in all the bloom of health, and yet all the rigours of abstemious discipline. Their common allowance, as we arc told, for four and twenty hours, was twelve ounces of bread, and nothing but water. On this simple beve- rage, St. Anthony is said to have lived a hun- dred and five years ; James, the hermit, an hun- dred and four ; Arsenius, tutor to the emperor Arcadius, an hundred and twenty ; St. Epipha- nius, an hundred and fifteen ; Simeon, an hundred and twelve ; and Rombald, an hun- dred and twenty. In this manner did these holy temperate men live to an extreme old age, kept cheerful by strong hopes, and healthful by moderate labour. Abstinence, which is thus voluntary, may be much more easily supported than constrained hunger. Man is said to live without food for seven days ; which is the usual limit assigned him ; and, perhaps, in a state of constraint, this is the longest time he can survive the want of it. But in cases of voluntary abstinence, of sickness, or sleeping, he has been known to live much longer. In the records of the Tower, there is an ac- count of a Scotchman, imprisoned for felony, who for the space of six weeks took not the least sustenance, being exactly watched during the whole time ; and for this he received the king's pardon. When the American Indians undertake long journeys, and when, consequently, a stock of provisions sufficient to support them the whole way, would be more than they could carry ; in order to obviate this inconvenience, instead of carrying the necessary quantity, they con- trive a method of palliating their hunger, by swallowing pills, made of calcined shells and tobacco. These pills take away all appetite, by producing a temporary disorder in the sto- mach ; and, no doubt, the frequent repetition of this wretched expedient must at last be fa- tal. By these means, however, they continue several days without eating, cheerfully bearing such extremes of fatigue and watching, as would quickly destroy men bred up in a grea- ter state of delicacy. For those arts by which we learn to obviate our necessities, do not 2G 156 A HISTORY OF fail to unfit us for their accidental encoun- ter. Upon the whole, therefore, man is less able to support hunger than any'other animal ; and he is not better qualified to support a state of watchfulness. Indeed, sleep seems much more necessary to him, than to any other crea- ture : as, when awake, he may be said to ex- haust a greater proportion of the nervous fluid ; and, consequently, to stand in need of an ade- quate supply. Other animals, when most awake, are but little removed from a state of slumber ; their feeble faculties, imprisoned in matter, and rather exerted by impulse than de- liberation, require sleep, rather as a cessation from motion, than from thinking. But it is otherwise with man ; his ideas, fatigued with their various excursions, demand a cessation, not less than the body, from toil : and he is the only creature that seems to require sleep from double motives ; not less for the refresh- ment of the mental, than of the bodily frame. There are some lower animals, indeed, that seem to spend the greatest part of their lives in sleep ; but, properly speaking, the sleep of such may be considered as a kind of death ; and their waking, a resurrection. Flies, and insects, are said to be asleep, at a time that all the vital motions have ceased, without res- piration, without any circulation of their juices; if cut in pieces, they do not awake, nor does any fluid ooze out at the wound. These may be considered rather as congealed than as sleeping animals ; and their rest, during win- ter, rather as a cessation from life, than a ne- cessary refreshment ; but in the higher races of animals, whose blood is not thus congealed, and thawed by heat, these all bear the want of sleep much better than man ; and some of them continue a long time without seeming to take any refreshment from it whatsoever. But man is more feeble ; he requires its due return ; and if it fails to pay the accustomed visit, his whole frame is in a short time thrown into disorder : his appetite ceases ; his spirits are dejected ; his pulse becomes quicker and harder ; and his mind, abridged of its slumber- ing visions, begins to adopt waking dreams. A thousand strange phantoms arise, which come and go without his will ; these, which are transient in the beginning, at last take firm possession of the mind, which yields to their dominion, and after a long struggle, runs into confirmed madness. In that horrid slate, the mind may be considered as a city without walls, open to every insult, and paying ho- mage to every invader ; every idea that then starts with any force, becomes a reality ; and the reason, over fatigued with its former im- portunities, makes no head against the tyran- nical invasion, but submits to it from mere imbecility. But it is happy for mankind, that this state of inquietude is seldom driven to an extreme ; and that there are medicines which seldom fail to give relief. However, man finds it more difficult than any other animal to pro- cure sleep : and some are obliged to court its approaches for several hours together, be- fore they incline to rest. It is in vain that all light is excluded ; that all sounds are re- moved ; that warmth and softness conspire to invite it ; the restless and busy mind still retains its former activity; and Reason, that wishes to lay down the reins, in spite of her- self, is obliged to maintain them. In this dis- agreeable state, the mind passes from thought to thought, willing to lose the distinctness of perception, by increasing the multitude of the images. At last, when the approaches of sleep are near, every object of the imagi- nation begins to mix with that next it; their outlines become, in a manner, rounder ; a part of their distinctions fade away; and sleep, that ensues, fashions out a dream from the remainder. If then it should be asked from what cause this state of repose proceeds, or in what man- ner sleep thus binds us for several hours to- gether ? I must fairly confe'ss my ignorance ; although it is easy to tell what philosophers say upon the subject. Sleep, says one of them," consists in a scarcity of spirits, by which the orifices or pores of the nerves in the brain, through which the spirits used to flow into the nerves, being no longer kept open by the frequency of the spirits, shut of themselves ; thus the nerves, wanting a new supply of spirits, become lax, and unfit to con- vey any impression to the brain. All this, however, is explaining a very great obscurity by somewhat more obscure ; leaving, there- fore, those spirits to open and shut the en- Rohauh. ANIMALS. 157 trances to the brain, let us be contented with simply enumerating the effects of sleep upon the human constitution. In sleep, the whole nervous frame is re- laxed, while the heart and the lungs seem more forcibly exerted. This fuller circula- tion produces also a swelling of the muscles, as they always find who sleep with ligatures on any part of their body. This increased circulation also, may be considered as a kind of exercise, which is continued through the frame ; and by this, the perspiration becomes more copious, although the appetite for food is entirely taken away. Too much sleep dulls the apprehension, weakens the memory, and unfits the body for labour. On the con- trary, sleep too much abridged, emaciates the frame, produces melancholy, and con- sumes the constitution. It requires some care, therefore, to regulate the quantity of sleep, and just to take as much as will com- pletely restore nature, without oppressing it. The poor, as Otway says, sleep little ; forced by their situation, to lengthen out their labour to their necessities, they have but a short inter- val for this pleasing refreshment; and I have ever been of opinion, that bodily labour de- mands a less quantity of sleep than mental. Labourers and artizans are generally satis- fied with about seven hours; but I have known some scholars who usually slept nine, and perceived their faculties no way impaired by oversleeping. The famous Philip Barrettiere, who was considered as a prodigy of learning at the age of fourteen, was known to sleep regularly twelve hours in the twenty-four ; the extreme activity of his mind, when awake, in some measure called for an adequate alternation of repose : and, I am apt to think, that when students stint themselves in this particular, they lessen the waking powers of the imagi- nation, and weaken its most strenuous exer- tions. Animals that seldom think, as was said, can very easily dispense with sleep ; and of men, such as think least, will, very probably, be satisfied with the smallest share. A life of study, it is well known, unfits the body for receiving tin's gentle refreshment ; tho approaches of sleep are driven off by thinking: when, therefore, it comes at last, we should not be too ready to interrupt its continuance. Sleep is, indeed, to some, a very agreeable period of their existence: audit has been a question in the schools, Which was most happy, the man who was a beggar by night, and a king by day ; or he who was a beggar by day, and a king by night ? It is given in favour of the nightly monarch, by him who first started the question : " For the dream,*' says he, " gives the full enjoyment of the dig- nity, without its attendant inconveniences ; while, on the other hand, the king, who sup- poses himself degraded, feels all the misery of his fallen fortune, without trying to find tho comforts of his humble situation. Thus, by day, both states have their peculiardistresses: but, by night, the exalted beggar is perfectly blessed, and the king completely miserable." All this, however, is rather fanciful than just; the pleasure dreams can give us, seldom reaches to our waking pitch of happiness : the mind often in the midst of its highest vi- sionary satisfactions, demands of itself, whe- ther it does not owe them to a dream ; and frequently awakes with the reply. But it is seldom, except in cases of the highest delight, or the most extreme uneasi- ness, that the mind has power thus to disen- gage itself from the dominion of fancy. In the ordinary course of its operations, it sub- mits to those numberless fantastic images that succeed each other, and which, like many of our waking thoughts, arc generally forgotten. Of these, however, if any, by their oddity, or their continuance, affect us strongly, they are then remembered ; and there have been some who felt their impressions so strongly, as to mistake them for realities, and to rank them among the past actions of their lives. There are others upon whom dreams seem to have a very different effect; and who, without seeming to remember their impres- sions the next morning, have yet shown, by their actions during sleep, that they were very powerfully impelled by their dominion. We have numberless instances of such per- sons who, while asleep, have performed many of the ordinary duties to which they had been accustomed when waking; and, with a ridiculous industry, have completed by night, what they failed doing by day. We are told, in the German Ephcmcrides, of a young stu- 2Ci 153 A HISTORY OF dent, who being enjoined a severe exercise by his tutor, went to bed, despairing of accom- plishing it. The next morning awaking, to his great surprise, he found the task fairly written out, and finished in his own hand- writing. He was at first, as the account has it, in- duced to ascribe this strange production to the operations of an infernal agent ; but his tutor, willing to examine the affair to the bot- tom, set him another exercise, still more severe than the former, and took precautions to observe his conduct the whole night. The young gentleman, upon being so severely tasked, felt the same inquietude that he had done on the former occasion ; went to bed gloomy and pensive, pondering on the next day's duty, and, after some time, fell asleep. But shortly after, his tutor, who continued to observe him from a place that was concealed, was surprised to see him get up, and very de- liberately go to the table ; where he took out pen, ink, and paper, drew himself a chair, and sat very methodically to thinking: it seems, that his being asleep, only served to strengthen the powers of his imagination ; for he very quickly and easily went through the task assigned him ; put his chair aside, and then returned to bed to take out the rest of his nap. What credit we are to give to this account, I will not pretend to determine ; but this may be said, that the book from whence it was taken, has some good marks of vera- city; for it is very learned, and very dull; and is written in a country noted, if not for truth, at least for want of invention. The ridiculous story of Arlotto is well known, who has had a volume written, con- taining a narrative of the actions of his life, not one of which was performed while he was awake. He was an Italian Franciscan friar, extremely rigid in his manners, and remarka- bly devout and learned in his daily conver- sation. By night, however, and during his sleep, he played a very different character from what he did by day, and was often de- tected in very atrocious crimes. He was at one time detected in actually attempting a rape, and did not awake till the next morning, when he was surprised to find himself in the hands of justice. His brothers of the convent often watched him while he went very deli- berately into the chapel, and there attempted to commit sacrilege. They sometimes permit- ted him to carry the chalice and the vest- ments away into his own chamber, and the next morning amused themselves at the poor man's consternation for what he had done. But of all his sleeping transgressions, thai was the most ridiculous, in which he was called to pray for the soul of a person de- parted. Arlotto, after having devoutly per- formed his duty, retired to a chamber which was shown him, to rest; but there he had no sooner fallen asleep, than he began to reflect that the dead body had got a ring upon one of the fingers, which might be useful to him : accordingly, with a pious resolution of steal- ing it, he went down, undressed as he was, into a room full of women, and, with great composure, endeavoured to seize the ring. The consequence was, that he was taken be- fore the inquisition for witchcraft; and the poor creature had like to have been con- demned, till his peculiar character acciden- tally came to be known : however, he was ordered to remain for the rest of life in his own convent, and upon no account whatso- ever to stir abroad. What are we to say to such actions as these ? or how account for this operation of the mind in dreaming ? It should seem, that the imagination, by day, as well as by night, is always employed ; and that often, against our wills, it intrudes, where it is least com- manded or desired. While awake, and in health, this busy principle cannot much de- lude us : it may build castles in the air, and raise a thousand phantoms before us ; but we have every one of the senses alive to bear testimony to its falsehood. Our eyes show us that the prospect is not present ; our hear- ing and our touch depose against its reality ; and our taste and smelling are equally vigi- lent in detecting the imposture. Reason, therefore, at once gives judgment upon the cause, and the vagrant intruder, Imagination, is imprisoned, or banished from the mind. But in sleep it is otherwise ; having, as much as possible, put our senses from their duty, having closed the eyes from seeing, and the ears, taste, and smelling, from their peculiar functions, and having diminished even the touch itself, by all the arts of softness, the ANIMALS. imagination is then left to riot at large, and to lead the understanding without an opposer. Every incursive idea then becomes a reality; and the mind, not having one power that can prove the illusion, takes them for truths. As in madness, the senses, from struggling with the imagination, are at length forced to sub- mit ; so, in sleep, they seem for a while sooth- ed into the like submission : the smallest violence exerted upon any one of them, how- ever, rouses all the rest in their mutual de- fence ; and the imagination, that had for a while told its thousand falsehoods, is totally driven away, or only permitted to pass under the custody of such as are every moment ready to detect its imposition. CHAPTER XXIX. OF SEEING." " HAVING mentioned the senses as cor- recting the errors of the imagination, and as forcing it, in some measure, to bring us just information, it will naturally follow, that we should examine the nature of those senses themselves: we shall thus be enabled to see how far they also impose on us, and how far they contribute to correct each other. Let it be observed, however, that in this we are neither giving a treatise of optics or phonics, but a history of our own perceptions : and to those we chiefly confine ourselves." The eyes very soon begin to be formed in the human embryo, and in the chicken also. Of all the parts which the animal has dou- ble, the eyes are produced the soonest, and appear the most prominent. It is true, indeed, that in viviparous animals, and particularly in man, they are not so large in proportion, at first, as in the oviparous kinds; nevertheless, they are more speedily developed, when they begin to appear, than any other parts of the body. It is the same with the organ of hear- ing ; the little bones that compose the inter- nal parts of the ear are entirely formed before the other bones, though much larger, hare acquired any part of their growth or solidity. Hence it appears, that those parts of the body which are furnished with the greatest quan- This chapter is taken from Mr. Buffbn. I believe the reader will readily excuse any apology ; and, perhaps, may wish that I had taken this liberty much more fre- quently. What I add is marked, as in a former instance, with inverted commas. tity of nerves, are the first in forming. Thus the brain and the spinal-marrow, are the first seen begun in the embryo ; and, in general, it may be said, that wherever the nerves go, or send their branches in great numbers, there the parts are soonest begun, and the most com- pletely finished. If we examine the eyes of a child some hours, or even some days, after its birth, it will be easily discerned that it as yet makes no use of them. The humours of the organ not having acquired a sufficient consistence, the rays of light strike but confusedly upon the retina, or expansion of nerves at the back of the eye. It is not till about a month after they are born, that children fix them upon objects ; for, before that time, they turn them indiscriminately every where, without appear- ing to be affected by any. At six or seven weeks old, they plainly discover a choice in the objects of their attention ; they fix their eyes upon the most brilliant colours, and seem peculiarly desirous of turning them towards the light. Hitherto, however, they only seem to fortify the organ for seeing distinctly ; but they have still many illusions to correct. The first great error in vision is, that the eye inverts every object : and it in reality ap- pears to the child, until the touch has served to undeceive it, turned upside down. A se- cond error in vision is, that every object ap- pears double. The same object forms itself distinctly upon each eye ; and is consequent- ly seen twice. This error, also, can only be 160 A HISTORY OF corrected by the touch ; and although, in re- ality, every object we see appears inverted ! and double, yet the judgment and habit have ' so often corrected the sense, that we no lon- ger submit to its imposition, but see every ' object in its just position, the very instant it ' appears. Were we, therefore, deprived of feeling, our eyes would not only misrepresent the situation, but also the number of all things ; around us. To convince us that we see objects invert- ed, we have only to observe the manner in ! which images are represented, coming through a small hole, in a darkened room. If such a | small hole be made in a dark room, so that | no light can come in, but through it, all the \ objects without will be painted on the wall behind, but in an inverted position, their heads downwards. For as all the rays which pass from the different parts of the object without, cannot enter the hole in the same ex- tent which they had in leaving the object; since, if so, they would require the aperture to be as large as the object; and, as each part, and every point of the object, sends forth the image of itself on every side, and the rays, which form these images, pass from all points of the object as from so many centres, so such only can pass through the small aperture as come in opposite directions. Thus the little aperture becomes a centre for the entire ob- j ject ; through which the rays from the up- per parts, as well as from the lower parts of it, pass in converging directions; and, conse- quently, they must cross each other, in the central point, and thus paint the objects be- hind, upon the wall, in an inverted position. It is, in like manner, easy to conceive, that we see all objects double, whatever our pre- sent sensations may seem to tell us to the con- trary. For to convince us of this, we have only to compare the situation of any one ob- ject on shutting one eye, and then compare the same situation by shutting the other. If, for instance, we hold up a finger, and shut the right eye, we shall find it hide a certain part of the room ; if again reshutting the other eye, we shall find that part of the room visible, i and the finger seeming to cover a part of the room that had been visible before. If we | open both eyes, however, the part covered j -wiH appear to lie between the two extremes. But the truth is, we see the object our finger had covered, one image of it to the right, and the other to the left ; but, from habit, suppose that we see but one image placed between both; our sense of feeling having corrected the errors of sight. And thus, also, if instead of two eyes we had two hundred, we should, at first, fancy the objects increased in pro- portion, until one sense had corrected the errors of another. 44 The having two eyes might thus be said to be rather an inconvenience than a benefit; since one eye would answer the purposes of sight as well, and be less liable to illusion. But it is otherwise ; two eyes greatly contri- bute, if not to distinct, at least to extensive vision.* When an object is placed at a mo- derate distance, by the means of both eyes we see a larger share of it than we possibly could with one ; the right eye seeing a grea- ter portion of its right side, and the left eye of its corresponding side. Thus both eyes, in some measure, see round the object; and it is this that gives it, in nature, that bold re- lievo, or swelling, with which they appear ; and which no painting, how exquisite soever, can attain to. The painter must be content- ed with shading on aflat surface; but the eyes, in observing nature, do not behold the shading only, but a part of the figure also, that lies behind (hose very shadings, which gives it that swelling, which painters so ar- dently desire, but can never fully imitate. " There is another defect, which either of the eyes, taken singly, would have, but which is corrected, by having the organ double. In either eye there is a point, which ha^ no vision whatsoever ; so that if one of them only is employed in seeing, there is a part of the object to which it is always totally blind. This is that part of the optic, nerve where its vein and artery run; which being insensible, that point of the object that is painted there must continue unseen. To be Convinced of this we have only to try a very easy experi- ment. If we take three black patches, and stick them upon a white wall, about a foot distant from each other, each about as high as the eye that is to observe them ; then re- tiring six or seven feet back, and shutting one " Leonardo da Vinci. AXIMALS. eye, by trying for some: time, we shall find, that while we distinctly behold the black spots that are to the ri>j;!jt and left, that which is in the middle remains totally unseen. Or, in other words, when we bring that part of the eye, where the optic artery runs, to fall upon the object, it will then become invisible. This defect, however, in either eye, is always corrected by both, since the part of the object that is unseen by one, will be very distinctly perorivrd by the other.'' Beside the former defects, we can have no idea of distances from the sight, without the help of touch. Naturally every object we see appears to be within our eyes ; and a child, who has as yet made but little use of the sense of feeling, must suppose that every thing it sees makes a part of itself. Such ob- jects are only seen more or less bulky as they approach, or recede from its eyes ; so that a lly that is near will appear larger than an ox at a distance. It is experience alone that can rectify this mistake ; and a long acquain- tance with the real size of every object, quick- ly assures us of the distance at which it is seen. The last man in a file of soldiers appears in reality much less, perhaps ten times more di- minutive, than the man next to us ; however, we do not perceive this difference, but con- tinue to think him of equal stature ; for the numbers we have seen thus lessened by dis- tance, and have found, by repeated experi- ence, to be of the natural size when we come closer, instantly correct the sense, and every object is perceived with nearly its natural proportion. But it is otherwise, if we observe objects in such situations as we have not had sufficient experience to correct the errors of the eye ; if, for instance, we look at men from the top of a high steeple, they, in that case, appear very much diminished, as we have not had a habit of correctitig the sense in that po- sition. Although a small degree of reflection will serve to convince us of the truth of these po- sitions, it may not be amiss to strengthen them by an authority which cannot be dispu- ted. Mr. Cheselden having couched a boy of thirteen for a cataract, who had hitherto been blind, and thus at once having restored him to sight, curiously marked the progress of his mind upon that occasion. This youth, though he had been till then incapable of see- ing, yet was not totally blind, but could tell day from night, as persons in his situation always may. He could also, with a strong light, distinguish black from white, and either from the vivid colour of scarlet : however, he saw nothing of the form of bodies ; and, with- out a bright light, not even colours themselves. He was, at first, couched only in one of his eyes; and when he saw for the first time, he was so far from judging of distances, that he supposed his eye touched every object tiia- he saw, in the same manner as his hands might be said to feel them. The objects that were most agreeable to him were such as were of plain surfaces and regular figures : though he could as yet make no judgment whatever of their different forms, nor give a reason why one pleased him more than another. Al- though he could form some idea of colours during his state of blindness, yet that was not sufficient to direct him at present; and he could scarcely be persuaded that the colours he now saw were the same with those he had formerly conceived such erroneous ideas of. He delighted most in green ; but black ob- jects, as if giving him an idea of his former blindness, he regarded with horror. He had, as was said, no idea of forms ; and was una- ble to distinguish one object from another, though never so different. When those things were shown him, which he had been former- ly familiarized to by his feeling, he beheld them with earnestness, in order to remember them a second time : but as he had too many to recollect at once, he forgot the greatest number ; and for one he could tell, after see- ing, there was a thousand he was totally un- acquainted with. He was very much sur- prised to find, that those things and persons he loved best, were not the most beautiful to be seen; and even testified displeasure in not finding his parents so handsome as he conceived them to be. It was near two months before he could find that a picture resembled a solid body. Till then he only considered it as a flat surface, variously shadowed ; but when he began to perceive that these kind of shadings actually represented human beings, he then began to examine, by his touch, whe- ther they had not the usual qualities of such bodies, and was .oreatly surprised to find, what A HISTORY OF he expected a very unequal surface, to be smooth and even. He was then shown a mi- niature-picture of his father, which was con- tained in his mother's watch-case, and he rea- dily perceived the resemblance; but asked, with great astonishment, how so large a face could be contained in so small a compass? It seemed as strange to him as if a bushel was contained in a pint vessel. At first he could bear but a very small quantity of light, and he saw erery object much greater than the life ; but, in proportion as he saw objects that were really large, he seemed to think the for- mer were diminished ; and although he knew the chamber where he was contained in the house, yet, until he saw the latter, he could not be brought to conceive how a house could be larger than a chamber. Before the ope- ration, he had no great expectations from the pleasure he should receive from a new sense; he was only excited by the hopes of being able to read and write ; he said, for instance, that he could hare no greater pleasure in walking in the garden with his sight, than he had without it, tor he walked there at his ease, and was acquainted with all the walks. He remarked also, with great justice, that his for- mer blindness gave him one advantage over the rest of mankind, which was that of being able to walk in the night with confidence and security. But when he began to make use of his new sense, he seemed transported be- yond measure. He said, that every new ob- ject was a new source of delight, and that his pleasure was so great as to be past expres- sion. About a year after, he was brought to Ep- som, where there is a very fine prospect, with which he seemed greatly charmed ; and he called the landscape before him a new me- thod of seeing. He was couched in the other eye, a year after the former, and the opera- tion succeeded equally well : when he saw with both eyes, he said that objects appear- ed to him twice as large as when he saw but with one; however, he did not see them dou- bled, or, at least, he showed no marks as if he saw them so. Mr. Cheselden mentions in- instances of many more that were restored to sight in this manner ; they all seemed to con- cur in their perceptions with this youth ; and all seemed particularly embarrassed in learning how to direct their eyes to the ob jects they wished to observe. In this manner it is that our feeling correct; the sense of seeing, and that objects which appear of very different sizes at different dis- tances, are all reduced, by experience, to their natural standard. " But not the feeling only, but also the colour and brightness ot the object, contributes, in some measure, to assist us in forming an idea of the distance at which it appears." Those which we see most strongly marked with light and shade, we rea- dily know to be nearer than those on which the colours are more faintly spread, and that, in some measure, take a part of their hue from the air between us and them. Bright objects also are seen at a greater distance than such as are obscure, and, most probably, for this reason, that being less similar in colour, to the air which interposes, their impressions are less effaced by it, and they continue more dis- tinctly visible. Thus a black and distant ob- ject is not seen so far off" as a bright and glit- tering one, and a fire by night is seen much farther off" than by day." The power of seeing objects at a distance is very rarely equal in both eyes. When this inequality is in any great degree, the person so circumstanced then makes use only of one eye, shutting that which sees the least, and employing the other with all its power. And hence proceeds that awkward look which is known by the name of strabism. There are many reasons to induce us to think that such as are near-sighted see objects larger than other persons ; and yet the con- trary is most certainly true, for they see them less. Mr. Buffbn informs us that he himself is short-sighted, and that hisleft eyeisstronger than his right. He has very frequently expe- rienced, upon looking at any object, such as the letters of a book, that they appear less to the weakest eye; and that when he places the book, so as that the letters appear double, the images of the left eye, which is strongest, are greater than those of the right, which is the most feeble. He has examined several others, who were in similar circumstances, and a Mr. Buffon gives a different theory, for which I must refer the reader to the original. That I have given, I take to be easy and satisfactory enough. ANIMALS. to;* has always found that the best eye saw every object the largest. This he ascribes to ha- bit; for near-sighted people being accustom- ed to come close to the object, and view but a small part of it at a time, the habit ensues, when the whole of an object is seen, and it appears less to them than to others. Infants, having their eyes less than those of adults, must see objects also smaller in pro- portion. For the image formed on the back of the eye will be large, as the eye is capaci- ous ; and infants, having it not so great, can- not have so large a picture of the object. This may be a reason also why they are un- able to see so distinctly, or at such distances, as persons arrived at maturity. Old men, on the contrary, see bodies close to them very indistinctly, but bodies at a great distance from them with more precision; and this may happen from an alteration in the coats, or, perhaps, humours of the eye ; and not, as is supposed, from their diminution. The cornea, for instance, may become too ri- gid to adapt itself, and take a proper convexi- ty for seeing minute objects ; and its very flatness will be sufficient tofit it fordistant vision. When we cast our eyes upon an object ex- tremely brilliant, or when we fix and detain them too long upon the same object, the organ is hurt and fatigued, its vision becomes indis- tinct, and the image of the body which has thus too violently, or too perseveringly em- ployed us, is painted upon every thing we look at, and mixes with every object that oc- curs. " And this is an obvious consequence of the eye taking in too much light, either im- mediately, or by reflection. Every body ex- posed to the light, for a time, drinks in a quan- tity of its rays, which being brought into dark- ness, it cannot instantly discharge. Thus the hand, if it be exposed to broad day-light for some time, and then immediately snatched into a dark room, will appear still lumi- nous : and it will be some time before it is to- tally darkened. It is thus with the eye; which, either by an instant gaze at the sun, or a steady continuance upon some less bril- liant object, has taken in too much light ; its humours are, for a while, unfit for vision, until that be discharged, and room made for rays of a milder nature." How dangerous the look- ing upon bright and luminous objects is to the NO. 15 & 16 sight, may be easily seen, from such as live in countries covered for most part of the year with snow, who become generally blind beibre their time. Travellers who cross these coun- tries are obliged to wear a crape before their faces, to save their eyes, which would other- wise be rendered totally unserviceable ; and it is equally dangerous in the sandy plains of Africa. The reflection of the light is there so strong, that it is impossible to sustain the effect without incurring the danger of losing one's sight entirely. Such persons, therefore, as read or write for any continuance, should choose a moderate light, in order to save their eyes ; and although it may seem insufficient al first, the eye will accustom itself to the shade, by degrees, and be less hurt by the want of light than the excess. " It is, indeed, surprising how far the eye can accommodate itself to darkness, and make the best of a gloomy situation. When first taken from the light, and brought into a dark room, all things disappear; or, if any thing is seen, it is only the remaining radiations that still continue in the eye. But, after a very little time, when these are spent, the eye takes the advantage of the smallest ray that happens to enter ; and this alone would, in time, serve for many of the purposes of life. There was a gentleman of great courage and under- standing, who was a major under King Charles I. ; this unfortunate man, sharing in his master's misfortunes, and being forced abroad, ventured at Madrid to do his king a signal service ; but unluckily failed in the attempt. In consequence of this, he was in- stantly ordered to a dark and dismal dun- geon, into which the light never entered, and into which there was no opening but by a hole at the top, down which the keeper put his provisions, and presently closed it again on the other side. In this manner the unfor- tunate loyalist continued for some weeks, dis- tressed and disconsolate ; but at last he be- gan to think he saw some little glimmering of light. This internal dawn seemed to in- crease from time to time, so that he could not only discover the parts of his bed, and such other large objects, but, at length, he even began to perceive the mice that frequented his cell ; and saw them as they ran about the floor, eating the crumbs of bread that happen- 2H 164 A HISTORY OF ed to fall. After some months' confinement I] not, for some days, venture to leave his dun- he was at last set free; but such was the ef- geori, but was obliged to accustom himself by feet of the darkness upon him, that he could jj degrees to the light of the day. CHAPTER XXX. OF HEARING." AS the sense of hearing, as well as of sight, gives us notice of remote objects, so, like that, it is subject to similar errors, being capable of imposing on us upon all occasions, where we cannot rectify it by the sense of feeling. We can have from it no distinct intelligence of the distance from whence a sounding body is heard ; a great noise far ofT, and a small one very near, produce the same sensation ; and unless we receive information from some other sense, we can never distinctly tell whe- ther the sound be a great or a small one. It is riot till we have learned, by experience, that the particular sound which is heard, is of a peculiar kind ; then we can judge of the distance from whence we hear it. When we know the tone of the bell, we can then judge how far it is from us. Every body that strikes against another pro- duces a sound, which is simple, and but one in bodies which are not elastic, but which is often repeated in such as are. If we strike a bell, or a stretched string, for instance, which are both elastic, a single blow produces a sound, which is repeated by the undulations of the sonorous body, and which is multiplied as often as it happens to undulate or vibrate. These undulations each strike their own pe- culiar blow; but they succeed so fast, one behind the other, that the ear supposes them one continued sound ; whereas, in reality, they make many. A person who should, for the first time, hear the toll of the bell, would very probably be able to distinguish these breaks of sound ; and, in fact, we can readily ourselves perceive an intention and premis- sion in the sound. In this manner, sounding bodies are of two 1 This chapter is taken from Mr. Bullbn, except where marked by inverted commas. kinds; those unelastic ones, which, being struck, return but a single sound ; and those more elastic, returning a succession of sounds; which uniting together, form a tone. This tone may be considered as a great number of sounds, all produced one alter the other, by the same body, as we find in a bell, or the string of a harpsichord, which continues to sound for some time after it is struck. A con- tinuing tone may also be produced from a non-elastic body, by repeating the blow quick and often, as when we beat a drum, or when we draw a bow along the string of a fiddle. Considering the subject in this light, if we should multiply the number of blows, or re- peat them at quicker intervals upon the sounding body, as upon the drum, for in- stance, it is evident that this will have no ef- fect in altering the tone ; it will only make it either more even, or more distinct. But it is otherwise, if we increase the force of the blow: if we strike the body with double weight, this will produce a tone twice as loud as the former. If, for instance, I strike a table with a switch, this will be very-different from the sound produced by striking it with a cud- gel. Hence, therefore, we may infer, that all bodies give a louder and a graver tone, not in proportion to the number of times they are struck, but in proportion to the force that strikes them. And, if this be so, those philo- sophers who make the tone of a sonorous body, of a bell, or the string of a harpsichord, for instance, to depend upon the number only of its vibrations, and not the force, have mis- taken what is only an effect for a cause. A bell, or an elastic string, can only be consi- dered as a drum beaten; and the frequency of the blows can make no alteration whatever in the tone. The largest bells, and the longest ANIMALS. 16f, and thickest strings, have the most forceful vibrations ; and, therefore, their tones are the most loud and the most grave. To know the manner in which sounds thus produced become pleasing, it must be observ- ed, no one continuing tone, how loud and swelling soever, can give us satisfaction ; we must have a succession of them, and those in the most pleasing proportion. The nature of this proportion may be thus conceived. If we strike a body incapable of vibration with a double force, or, what amounts to the same thing, with a double mass of matter, it will produce a sound that will be doubly grave. Music has been said, by the ancients, to have been first invented from blows of different hammers on an anvil. Suppose then we strike an anvil with a hammer of one pound weight, and again with a hammer of two pounds, it is plain that the two-pound hammer will produce a sound twice as grave as the former. But if we strike with a two-po'ind hammer, and then with a three-pound, it is evident that the latter will produce a sound one-third more grave than the former. If we strike the anvil with a three-pound hammer, and then with a four-pound, it will likewise follow that the latter will be a quarter part more grave than the former. Now, in the comparing between all those sounds, it is ob- vious that the difference between one and fwo is more easily perceived, than between two and three, three and four, or any numbers succeeding in the same proportion. The suc- cession of sounds will be, therefore, pleasing in proportion to the ease with which they may be distinguished. That sound which is double the former, or, in other words, the oc- tave to the preceding tone, will, of all others, be the most pleasing harmony. The next to that which is as two to three, or, in other words, the thirl, will be most agreeable. And thus, universally, those sounds whose differ- ence may be most easily compared, are the most agreeable. " Musicians, therefore, have contented themselves with seven different proportions of sound, which are called notes, and which sufficiently answer all the purposes of plea- sure. Not but that they might adopt a grea- ter diversity of proportions ; and some have actually done so ; but, in these, the differences of the proportion are so imperceptible, that the ear is rather fatigued than pleased in making the distinction. In order, however, to give variety, they have admitted halftones: but in all the countries where music is yet in its infancy, they have rejected such ; and they can find music in none but the obvious ones. The Chinese, for instance, have neither flats nor sharps in their music; but the intervals between their other notes, are in the same proportion with ours. " Many more barbarous nations have their peculiar instruments of music ; and, what is remarkable,the proportion between their notes is in all the same as in ours. This is not the place for entering into the nature of these sounds, their effects upon the air,or their con- sonances with each other. We are not now giv- ing a history of sound, but of human perception. " All countries are pleased with music ; and if they have not skill enough to produce harmony, at least they seem willing to substi- tute noise. Without all question, noise alone is sufficient to operate powerfully on the spirits ; and, if the mind be already predis- posed to joy, I have seldom found noise fail of increasing it into rapture. The mind feels a kind of distracted pleasure in such power- ful sounds, braces up every nerve, and riots in the excess. But, as in the eye, an imme- diate gaze upon the sun will disturb the or- gans, so, in the ear, a loud unexpected noise- disorders the whole frame, arid sometimes disturbs the sense ever after. The mind must have time to prepare for the expected shock, and to give its organs the proper ten- sion for its arrival. " Musical sounds, however, seem of a differ- ent kind. Those are generally most pleasing which are most unexpected. It is not from bracing up the nerves, but from the grateful successionof the sounds, that these become so charming. There /are few, how indifferent soever, but have at times felt their pleasing im- pressions; and, perhaps, even those who have stood out against the powerful persuasion of sounds, only wanted the proper tune, or the proper instrument, to allure them. " The ancients give us a thousand strange instances of the effects of music upon men and animals. The story of Arion's harp, that gathered the dolphins to the ship's side, is well 211* 166 A HISTORY OF known ; and what is remarkable, Scholteus assures us," that he saw a similar instance of fishes being allured by music. They tell us of diseases that have been cured, unchastity corrected, seditions quelled, passions re- moved, and sometimes excited even to mad- ness. Dr. Wallis has endeavoured to account for these surprising effects, by ascribing them to the novelty of the art. For my own part, J can scarcely hesitate to impute them to the exaggeration of the writers. They are as hy- perbolical in the effects of their oratory ; and yet, we well know, there is nothing in the ora- tions which they have left us, capable of ex- citing madness, or of raising the mind to that ungovernable degree of fury which they de- scribe. As they have exaggerated, therefore, in one instance, we may naturally suppose that they have done the same in the other; and, indeed, from the few remains we have of their music, collected by Meibornius, one might be apt to suppose there was nothing very powerful in what is lost. Nor does any one of the ancient instruments, such as we see them represented in statues, appear com- parable to our fiddle. " However this be, we have many odd ac- counts, not only among them, but the mo- derns, of the power of music ; and it must not be denied, but that, on some particular oc- casions, musical sounds may have a very pow- erful effect. I have seen all the horses and cows in a field, where there were above a hundred, gathered round a person that was blowing a French horn, and seeming to tes- tify an awkward kind of satisfaction. Dogs are well known to be very sensible of dif- ferent tones in music ; and I have sometimes heard them sustain a very ridiculous part in a concert, where their assistance was neither expected nor desired. " We are told of Henry IV. of Denmark, 11 that being one day desirous of trying in person whether a musician, who boasted that he could excite men to madness, was not an impostor, he submitted to the operation of his skill : but the consequence was much more terrible than he expected ; for, becom- ing actually mad, he killed four of his atten- a Quod oculis meis spectavi. Schotti Magic, univer- aalis, pars. ii. lib. 1. p. 26. dants in the midst of his transports. A con- trary effect of music we have, c in the cure of a madman of Alais, in France, by music. This man, who was a dancing-master, after a fever of five days, grew furious, and so un- governable that his hands were obliged to be tied to his sides : what at first was rage, in a short time was converted into silent melan- choly, which no arts could exhilarate, nor no medicines remove. In this sullen and de- jected state, an old acquaintance accidentally came to inquire after his health ; he found him sitting up in bed, tied, and totally regard- less of every external object around him. Happening, however, to take up a fiddle that lay in the room, and touching a favourite air, the poor madman instantly seemed to brighten up at the sound ; from a recumbent posture, he began to sit up ; and, as the musician con- tinued playing, the patient seemed desirous of dancing to the sound : but he was tied, and incapable of leaving his bed, so that he could only humour the tune with his head, and those parts of his arms which were at liberty. Thus the other continued playing, and the dancing-master practised his own art, as far as he^as able, for about a quarter of an hour, when suddenly falling into a deep sleep, in which his disorder came to a crisis, he awaked perfectly recovered. ""A. thousand other instances might be add- ed, equally true : let it suffice to add one more, which is not true ; I mean that of the taran- tula. Every person who has been in Italy now well knows, that the bite of this animal, and its being cured by music, is all a decep- tion. When strangers come into that part of the country, the country people are ready enough to take money for dancing to the tarantula. A friend of mine had a servant who suffered himself to be bit ; the wound, which was little larger than the puncture of a pin, was uneasy for a few hours, and then be- came well without any farther assistance. Some of the country people however, still make tolerable livelihood of the credulity of strangers, as the musician finds his account in it not less than the dancer." Sounds, like light, are not only extensively b Olai Magni, 1. 15. hist. c. 28. c Hist, de 1'Acad. 1708. p. 22. ANIMALS. 167 diffused, but are frequently reflected. The laws of this reflection, it is true, are not as well understood as those of light ; all we know is, that sound is principally reflected by hard bodies ; and their being hollow; also, sometimes increases the reverberation. " No art, however, can make an echo ; and some who have bestowed great labour and expense upon such a project, have only erected shape- less buildings, whose silence was a mortifying lecture upon their presumption." The internal cavity of the ear seems to be fitted up for the purpose of echoing sound with the greatest precision. This part is fa- shioned out in the temporal bone, like a ca- vern cut into a rock. " In this the sound is repeated and articulated ; and, as some ana- tomists tell us, (for we have as yet but very little knowledge on this subject,) is beaten against the tympanum, or drum of the ear, which moves four little bones joined thereto; and these move and agitate the internal air which lies on the other side; and lastly, this air strikes and affects the auditory nerves, which carry the sound to the brain." One of the most common disorders in old age is deafness ; which probably proceeds from the rigidity of the nerves in the labyrinth of the ear. This disorder, also, sometimes proceeds from a stoppage of the wax, which art may easily remedy. In order to know whether the defect be an internal or an ex- ternal one, let the deaf person put a repeat- ing watch into his mouth, and if he hears it strike, he may be assured that his disorder proceeds from an external cause, and is, in some measure, curable : " for there is a pas- sage from the ears into the mouth, by what anatomists call the eustachian tube ; and, by this passage, people often hear sounds, when they are utterly without hearing through the larger channel : and this also is the reason that we often see persons who listen with great attention, hearken with their mouths open, in order to catch all the sound at every aperture." It often happens, that persons hear diffe- rently with one ear from the other ; and it is generally found that these have what is call- ed, by musicians, a bad ear. Mr. Buffon, who has made many trials upon persons of this kind, always found that their defect in judging properly of sounds proceeded from the inequality of their ears ; and receiving by both, at the same time, unequal sensations, they form an unjust idea. In this manner, as those people hear false, they also, without knowing it, sing false. Those persons also frequently deceive themselves with regard to the side from whence the sound comes, gene- rally supposing the noise to come on the part of the best ear. Such as are hard of hearing, find the same advantage in the trumpet made for this pur- pose, that short-sighted persons do from glasses. These trumpets might be easily im- proved so as to increase sounds, in the same manner that the telescope does objects ; how- ever, they could be used to advantage only in a place of solitude and stillness, as the neighbouring sounds would mix with the more distant, and the whole would produce in the ear nothing but tumult and confusion. Hearing is a much more necessary sense to man than to animals. With these it is only a warning against danger, or an encourage- ment to mutual assistance. In man, it is the source of most of his pleasure; and without which the rest of his senses would be of little benefit. A man born deaf, must necessarily be dumb ; and his whole sphere of knowledge must be bounded only by sensual objects. We have an instance of a young man, who, being born deaf, was restored at the age of twenty-four to perfect hearing : the account is given in the Memoirs of the Academy of Sciences, 1703, page 18. A young man, of the town of Chartres, be- tween the age of twenty-three and twenty- four, the son of a tradesman, and deaf and dumb from his birth, began to speak all of a sudden, to the great astonishment of the whole town. He gave them to understand, that about three or four months before, he had heard the sound of the bells for the first time, and was greatly surprised at this new and un- known sensation. After some time, a kind of water issued from his left ear, and he then heard perfectly well with both. During these three months, he was sedulously employed in listening without saying a word, and accus- toming himself to speak softly (so as not to be heard) the words pronounced by others. He laboured hard also in perfecting himself 168 A HISTORY OF in the pronunciation, and in the ideas attached to every sound. At length, having supposed himself qualified to break silence, he declared, that he could now speak, although as yet but imperfectly. Soon after, some able divines questioned him concerning his ideas of his past state ; and principally with respect to God, his soul, the morality or turpitude of actions. The young man, however, had not driven his solitary speculations into that channel. He had gone to mass indeed with his parents, and learned to sign himself with the cross, to kneel down and assume all the grimaces of a man that was praying ; but he did all this without any manner of knowledge of the intention or the cause ; he saw others do the like, and that was enough for him ; he knew nothing even of death, and it never entered into his head ; he led a life of pure animal instinct ; entirely taken up with sensible objects, and such as were present, he did not seem even to make as many reflections upon these, as might reason- ably be expected from his improving situation; and yet the young man was not in want of understanding; but the understanding of a man deprived of all commerce with others, is so very confined, that the mind is in some measure totally under the control of its imme- diate sensations. Notwithstanding, it is very possible to com- municate ideas to deaf men, which they pre- viously wanted, and even give them very pre- cise notions of some abstract subjects, by means of signs and of letters. A person born deaf, may, by time, and sufficient pains, be taught to write and read, to speak, and by the motions of the lips, to understand what is said to him ; however, it is probable that, as most of the motions of speech are made within the mouth by the tongue, the knowledge from the motion of the lips is but very confined : " nevertheless, I have conversed with a gentleman thus taught, and in all the commonly occurring questions, and the usual salutations, he was ready enough, merely by attending to the motion of the lips alone. When I ventured to speak for a short continuance, he was totally at a loss, although he understood the subject, when written, ex- tremely well." Persons taught in this manner, were at first considered as prodigies ; but there have been so many instances of success of late, and so many are skilful in the art of instruct- ing in this way, that though still a matter of some curiosity, it ceases to be an object of wonder. CHAPTER XXXI. OF SMELLING, FEELING, AND TASTING. AN animal may be said to fill up that sphere which he can reach by his senses ; and is ac- tually large in proportion to the sphere to which its organ extends. By sight, man's enjoyments are diffused into a wide circle ; that of hearing, though less widely diffused, nevertheless ex- tends his powers ; the sense of smelling is more contracted still ; and the taste and touch are the most confined of all. Thus man enjoys very distant objects but with one sense only ; more nearly he brings two senses at once to bear upon them ; his sense of smelling assists the other two, at its own distance ; and of such objects, as a man, he may be said to be in per- fect possession. Each sense, however, the more it acts at a distance, the more capable it is of making com- binations; and is, consequently, the more im- ! proveable. Refined imaginations, and men of strong minds, take more pleasure, therefore, in improving the delights of the distant senses, than in enjoying such as are scarce capable of I improvement. By combining the objects of the extensive senses, all the arts of poetry, painting, and harmony, have been discovered ; but the closer jj senses, if I may so call them, such as smelling, tasting, and touching, are, in some measure, as simple as they are limited, and admit of | little variety. The man of imagination makes i a great and artificial happiness by the pleasure of altering and combining; the sensualist just 1 stops where he began, and cultivates only those ! pleasures which he cannot improve. The sea ANIMALS sualist is contented with those enjoyments that are already made to his hand ; but the man of pleasure is best pleased with growing happi- ness. Of all the senses, perhaps, there is not one in which man is more inferior to other animals than in that of smelling. With man, it is a sense that acts in a narrow sphere, and disgusts almost as frequently as it gives him pleasure. With many other animals it is diffused to a very great extent ; and never seems to offend them. Dogs not only trace the steps of other animals, but also discover them by the scent at a very great distance ; and while they are thus exquisitely ensible of all smells, they seem no way disgusted by any. But, although this sense is, in general, so very inferior in man, it is much stronger in those nations that abstain from animal food, than among Europeans. The Bramins of India have a power of smelling, as I am informed, equal to what it is in most other creatures. They can smell the water which they drink, that to us seems quite inodorous ; and have a word, in their language, which denotes a country of fine water. We are told also, that the negroes of the Antilles, by the smell alone, can distinguish between the footsteps of a Frenchman and a negro. It is possible, there- fore, that we may dull this Tgan by our luxuri- ous way of living ; and sacrifice to the pleasures of taste, those which might be received from perfume. However, it is a sense that we can, in some measure, dispense with ; and I have known many that wanted it entirely, with but very little inconvenience from its loss. In a state of nature it is said to be useful in guiding us to proper nourishment, and deterring us from that which is unwholesome ; but, in our present situation, such information is but little wanted ; and, indeed, but little attended to. In fact, the sense of smelling gives us very often false intelligence. Many things that have a disagree- able odour, are, nevertheless, wholesome and pleasant to the taste ; and such as make eating an art, seldom think a meal fit to please the appe- titp, till it begins to offend the nose. On the otlipr hand, there are many things that smell mot gratefully, and yet are noxious, or fatal to the constitution. Some physicians think that perfunii-s ingeneralare unwholesome; thatthey relax the nerves, produce head-aches, and even retard digestion. The manchineel apple, which is known to be deadly poison, is possessed of the most grateful odour. Some of those mine- ral vapours that are often found fatal in the stomach, smell like the sweetest flowers, and continue thus to flatter till they destroy. This sense, therefore, as it should seem, was never meant to direct us in the choice of food, but appears rather as an attendant than a necessary pleasure. Indeed, if we examine the natives of different countries, or even different natives of the same, we shall find no pleasure in which they differ so widely as that of smelling. Some persons are pleased with the smell of a rose ; while I have known others that could not abide to have it approach them. The savage nations are highly delighted with the smell of assafcetidn, which is to us the most nauseous stink in nature. It would in a manner seem that our delight in perfumes was made by habit ; and that a very little industry could bring us totally to invert the perception of odours. Thus much is certain, that many bodies which at one distance are an agreeable perfume, when nearer are a most ungrateful odour. Musk and ambergrise, in small quantities, are considered by most persons as highly fragrant; and yet, when in larger masses, their scent is insufferable. From a mixture of two bodies, each whereof is, of itself, void of all smell, a very powerful smell may be drawn. Thus, by grinding quick-lime with sal-ammoniac, may be produced a very fcetid mixture. On the contrary, from a mixture of two bodies, that are separately disagreeable, a very pleasant aromatic odour may be gained. A mixture of aqua-fortis with spirit of wine produces this effect. But not only the alterations of bodies by each other, but the smallest change in us, makes a very great alteration in this sense, and frequently deprives us of it totally. A slight cold often hinders us from smelling ; and as often changes the nature of odours. Some persons, from disorder, retain an incurable aversion to those smells which most pleased them before : and many have been known to have an antipathy to some animals, whose presence they instantly perceived by the smell. From all this, therefore, the sense of smelling appears to be an uncertain monitor, easily dis- ordered, and not much missed when totally wanting. 170 A HISTORY OF The sense most nearly allied to smelling is that of tasting. This, some have been willing to consider merely as a nicer kind of touch, and have undertaken to account, in a very mechanical manner, for the difference of sa- vours. " Such bodies," said they, " as are pointed, happening to be applied to the papillte of the tongue, excite a very powerful sensation, and give us the idea of saltness. Such, on the contrary, as are of a rounder figure, slide smoothly along the papillae, and are perceived to be sweet." In this manner they have with minute labour, gone through the variety of imagined forms in bodies, and have given them as imaginary effects. All we can precisely determine upon the nature of tastes is, that the bodies to be tasted must be either somewhat moistened, or, in some measure, dissolved by the saliva, before they can produce a proper sensation : when both the tongue itself and the body to be tasted are extremely dry, no taste whatever ensues. The sensation is then chang- ed ; and the tongue instead of tasting, can only be said, like any other part of the body, to feel the object. It is for this reason that children have a stronger relish of tastes than those who are more advanced in life. This organ with them, from the greater moisture of their bodies, is kept in greater perfection ; and is, consequent- ly, better adapted to perform its functions. Every person remembers how great a pleasure he found in sweets, while a child ; but his taste growing more obtuse with age, he is obliged to use artificial means to excite it. It is then that he is found to call in the assistance of poignant sauces, and strong relishes of salts and aroma- tics ; all which the delicacy of his tender organ in childhood was unable to endure. His taste grows callous to the natural relishes, and is artificially formed t others more unnatural ; so that the highest epicure may be said to have the most depraved taste ; as it is owing to the bluntness of his organ, that he is obliged to have recourse to such a variety of expedients to gratify his appetite. As smells are often rendered agreeable by habit, so also tastes may be. Tobacco and coffee, so pleasing to many, are yet, atfirst,very disagreeable to all. It is not without perseve- rance that we begin to have a relish for them ; we force nature so long, that what was constraint in the beginning, at last becomes inclination. The grossest, and yet the most useful of all the senses, is that of feeling. We are often seen to survive under the loss of the rest ; but of this we can never be totally deprived, but with life. Although this sense is diffused over all parts of the body, yet it most frequently happens that those parts which are most exer- cised in touching, acquire the greatest degree of accuracy. Thus the fingers, by long habit, become greater masters in the art than any other, even where the sensation is more delicate and fine." It is from this habit, therefore, and their peculiar formation, and not as is suppos- ed, from their being furnished with a greater quantity of nerves, that the fingers are thus perfectly qualified to judge of forms. Blind men, who are obliged to use them much oftener, have this sense much finer; so that the delicacy of the touch arises rather from the habit of constantly employing the fingers, than from any fancied nervousness in their conformation. All animals that are furnished with hands" seem to have more understanding than others. Monkeys have so many actions like those of men, that they appear to have similar ideas of the form of bodies. All other creatures, deprived of hands, can have no distinct ideas of the shape of the objects by which they are surrounded, as they want this organ, which serves to examine and measure their forms, their risings, and depressions. A quadruped, probably, conceives as erroneous an idea of any thing near him, as a child would of a rock or a mountain that it beheld at a distance. It may be for this reason, that we often see them frighted at things with which they ought to be better acquainted. Fishes, whose bodies are covered with scales, and who have no organs for feeling, must be the most stupid of all animals. Serpents, that are likewise desti- tute, are yet, by winding round several bodies, better capable of judging of their form. All these, however, can have but very imperfect ideas from feeling; and we have already seen, when deprived of this sense, how little the rest of the senses are to be relied on. The feeling, therefore, is the guardian, the judge, and the examiner of all the rest of the senses. It establishes their information, and detects their errors. All the other senses are altered by time, and contradict their former Buffon, vol. vi. p. 80. b Ibid. vol. vi. p. 82. ANIMALS. 171 evidence ; but the touch still continues the same ; and, though extremely confined in its operations, yet it is never found to deceive. The universe, to a man who had only used the rest of his senses, would be but a scene of illusion ; every object misrepresented, and all its properties unknown. Mr. Button has im- agined a man justnewly brought into existence, describing the illusion of his first sensations, and pointing out the steps by which he arrived at reality. He considers him as just created, and awaking amidst the productions of nature ; and, to animate the narrative still more strong- ly, has made his philosophical man a speaker. The reader will no doubt recollect Adam's speech in Milton as being similar. All that I can say to obviate the imputation of plagiarism is, that the one treats the subject more as a poet, the other more as a philosopher. The philosopher's man describes his first sensations in the following manner." I well remember that joyful anxious moment when I first became acquainted with my own existence. I was quite ignorant of what I was, bow I was produced, or from whence I came. I opened my eyes ; what an addition to my surprise ! the light of the day, the azure vault of heaven, the verdure of the earth, the crystal of the waters, all employed me at once, and animated and filled me with inexpressible de- light. I at first imagined that all those objects were within me, and made a part of myself. Impressed with this idea, I turned my eyes to the sun ; its splendour dazzled and over- powered me: I shut them once more; and, to my great concern, I supposed that during this short interval of darkness, I was again return- ing to nothing. Afflicted, seized with astonishment, I ponder- ed a mo.nent on this great change, when I heard a variety of unexpected sounds. The whistling of the wind, and the melody of the groves, formed a concert, the soft cadence of which sunk upon my soul. I listened for some time, and was persuaded that all this music was within me. Quite occupied with this new kind of ex- istence, I had already forgotten the light, which was my first inlet into life ; when I once more opened my eyes, and found myself again in possession of my former happiness. The gra- Buffbn, vol. vi. p. 88. tification of the two senses at once, was a pleasure too great for utterance. I turned my eyes upon a thousand various objects; I soon found that I could lose them, and restore them at will ; and amused myself more at leisure with a repetition of this new- made power. I now began to gaze without emotion, and to hearken with tranquillity, when a light breeze, the freshness of which charmed me, wafted its perfumes to my sense of smelling, and gave me such satisfaction as even increas- ed my self-love. Agitated, roused by the various pleasures of my new existence, I instantly arose, and per- ceived myself moved along, as if by some un- known and secret power. I had scarcely proceeded forward, when the novelty of my situation once more render- ed me immoveable. My surprise returned ; 1 supposed that every object around me had been in motion ; I gave to them that agitation which I produced by changing place ; and the whole creation seemed once more in disorder. I lifted my hand to my head ; I touched my forehead ; I felt my whole frame : I then sup- posed that my hand was the principal organ of my existence ; all its informations were distinct and perfect, and so superior to the senses I had yet experienced, that I employed myself for some time in repeating its enjoy- ments ; every part of my person I touched, seemed to touch my hand in turn ; and gave back sensation for sensation. 1 soon found that this faculty was expanded over the whole surface of my body ; and I now first began to perceive the limits of my existence, which I had in the beginning supposed spread over all the objects I saw. Upon casting my eyes upon my body, and surveying my own form, I thought it greater than all the objects that surrounded me. I gaz- ed upon rny person with pleasure ; I examined the formation of my hand, and all its motions; it seemed to me large or little in proportion as I approached it to my eyes ; I brought it very near, and it then hid almost every other object from my sight. I began soon, however, to find that my sight gave me uncertain informa- tion, and resolved to depend upon my feeling for redress. This precaution was of the utmost service ; I renewed my motions, and walked forward 21 172 A HISTORY OF with my face turned towards the heavens. I happened to strike lightly against a palm-tree, and this renewed my surprise : I laid my hand on this strange body ; it seemed replete with new wonders, for it did not return me sensa- tion for sensation, as my former feelings had done. I perceived that there was something external, and which did not make a part of my own existence. I now, therefore, resolved to touch whatever I saw, and vainly attempted to touch the sun ; I stretched forth my arm, and felt only yielding air : at every effort, I fell from one surprise in- to another, for every object appeared equally near me ; and it was not till after an infinity of trials, that I found some objects farther re- moved than the rest. Amazed with the illusions, and the uncer- tainty of my state, I sat down beneath a tree ; the most beautiful fruits hung upon it, within my reach ; I stretched forth my hand, and they instantly separated from the branch. I was proud of being able to grasp a substance with- out me ; I held them up, and their weight ap- peared to me like an animated power that en- deavoured to draw them to the earth. I found a pleasure in conquering their resistance. I held them near my eye ; I considered their form and beauty ; their fragrance still more allured me to bring them nearer ; I approach- ed them to my lips, and drank in their odours ; the perfume invited my sense of tasting, and 1 soon tried a new sense How new ! how ex- quisite ! Hitherto I had tasted only of pleasure ; but now it was luxury. The power of tasting gave me the idea of possession. Flattered with this new acquisition, I con- tinued its excercise, till an agreeable languor stealing upon my mind, I felt all my limbs be- come heavy, and all my desires suspended. My sensations were now no longer vivid and distinct ; but seemed to lose every object, and presented only feeble images, confusedly mark- ed. At that instant I sunk upon the flowery bank, and slumber seized me. All now seem- ed once more lost to me. It was then as if I was returning to my former nothing. How long my sleep continued, I cannot tell ; as I yet had no perception of time. My awaking appeared like a second birth ; ami I then per- ceived that I had ceased for a time to exist. This produced a new sensation of fear ; and from this interruption in life, I began to con- clude that I was not formed to exist for ever. In this state of doubt and perplexity, I be- gan to harbour new suspicions ; and to frar that sleep had robbed me of some of my late powers ; when turning on one side, to resolve my doubts, what was my amazement, to be- hold another being like myself, stretched by my side ! New ideas now began to arise ; new passions, as yet unperceived, with fears and pleasures, all took possession of my mind, and prompted my curiosity : love served to complete that happiness which was begun in the individual ; and every sense was gratified in all its varieties. CHAPTER XXXII. OF OLD AGE AND DEATH. 1 EVERY thing in nature has its improve- ment and decay. The human form is no soon- er arrived at its state of perfection, than it be- gins to decline. The alteration is at first in- sensible ; and often several years are elap- sed before we find ourselves grown old. The news of this disagreeable change too gene- rally comes from without ; and we learn from This chapter is taken from Mr. Buffon, except where it is marked by inverted commas. others that we grow old, before we are wil- ling to believe the report. When the body has come to its full height, and is extended into its justdimensions; it then also begins to receive an additional bulk, which rather loads than assists it. This is formed from fat; which generally at the age of thirty- five, or forty, covers all the muscles, and inter- rupts their activity. Every action is then per- formed with greater labour, and the increase of size only serves as a forerunner of decay. ANIMALS. 173 The bones, also, become every day more solid. In the embryo they are as soft almost as the muscles of the flesh ; but by degrees they harden, and acquire their natural vigour; but still, however, the circulation is carried on through them, and, how hard soever the bones may seem, yet the blood holds its cur- rent through them, as through all other parts of the body. Of this we may he convinced, by an experiment, which was first accidental- ly discovered by our ingenious countryman Mr. Belcher. Perceiving at a friend's house, that the bones of hogs, which were fed upon madder, were red, he tried it upon various animals by mixing this root with their usual food ; and he found that it tinctured the bones in all ; an evident demonstration that the jui- ces of the body had a circulation through the bones. He fed some animals alternately upon madder and their common food, for some time, and he found their bones tinctured with alternate layers, in conformity to their man- ner of living. From all this he naturally con- cluded, that the blood circulated through the bones, as it does through every other part of the body; and that, how solid soever they seemed, yet, like the softest parts, they were furnished through all their substance, with their proper canals. Nevertheless, these ca- nals are of very different capacities, during the different stages of life. In infancy they are capacious ; and the blood flows almost as freely through the bones as through any other part of the body : in manhood their size is greatly diminished ;. their vessels are almost imperceptible; and the circulation through them is proportionably slow. But, in the de- cline of life, the blood which flows through the bones, no longer contributing to their growth, must necessarily serve to increase their hardness. The channels that every where run through the human frame, may be compared to those pipes that we every where see crusted on the inside, by the water, for a long continuance, running through them. Both every day grow less and less, by the small rigid particles which are deposited within them. Thus as the vessels are by de- grees diminished, the juices also, which were necessary for the circulation through them, are diminished in proportion ; till at length, in old age, those props of the human frame are not only more solid, but more brittle. The cartilages, or gristles, which may be considered as bones beginning to be formed, grow also more rigid. The juices circulating through them, for there is a circulation through all parts of the body, every day contribute to render them harder ; so that these substances, which, in youth, are elastic and pliant, in age become hard and bony. As these cartilages are generally placed near the joints, the mo- tion of the joints also must, of consequence, be- come more difficult. Thus, in old age, every action of the body is performed with labour ; and the cartilages, formerly so supple, will now sooner break than bend. " As the cartilages acquire hardness, and un- fit the joints for motion, so also that mucous li- quor, which is always separated between the joints, and which serves, like oil to a hinge, to give them an easy and ready play, is now grown more scanty. It becomes thicker, and more clammy, more unfit for answering the purposes of motion ; and from thence, in old age, every joint is not only stiff, but awkward. At every motion this clammy liquor is heard to crack ; and it is not without the greatest effort of the muscles that its resistance is over- come. I have seen an old person, who never moved a single joint, that did not thus give no- tice of the violence done to it." The membranes that cover the bones, the joints, and the rest of the body, become, as we grow old, more dense and more dry. Those which surround the bones, soon cease to be ductile. The fibres, of which the muscles or flesh is composed, become every day more ri- gid ; and while to the touch the body seems, as we advance in years, to grow softer, it is, in reality increasing in hardness. It is the skin, and not the flesh, that we feel upon'such occasions. The fat, and the flabbiness of that, seems to give an appearance of softness, which the flesh itself is very far from having. There are few can doubt this, after trying the differ- ence between the flesh of young and old ani- mals. The first is soft and tender, the last is hard and dry. The skin is the only part of the body that age does not contribute to harden. That stretches to every degree of tension ; and we have horrid instances of its pliancy, in many disorders incident to humanity. * In youth 21* 174 A HISTORY OF therefore, while the body is vigorous and in- creasing, it still gives way to its growth. But, although it thus adapts itself to our increase, it does not in the same manner conform to our decay. The skin, which, in youth was filled and glossy, when the body begins to decline has not elasticity enough to shrink entirely with its diminution. It hangs, therefore, in wrinkles, which no art can remove. The wrinkles of the body, in general, proceed from this cause. But those of the face seem to proceed from another; namely, from the many varieties of positions into which it is put by the speech, the food, or the passions. Every grimace, and every passion, wrinkles up the visage into different forms. These are visible enough in young persons : but what at first was accidental or transitory, be- eomes unalterably fixed in the visage as it grows older. " From hence we may conclude, that a freedom from passions not only adds to the happiness of the mind, but preserves the beauty of the face; and the person that has not felt their influence, is less strongly marked by the decays of nature." Hence, therefore, as we advance in age, the bones, the cartilages, the membranes, the flesh, the skin, and every fibre of the body, become more solid, more brittle, and more dry. Every part shrinks, every motion be- comes more slow : the circulation of the fluids is performed with less freedom ; perspiration diminishes ; the secretions alter ; the diges- tion becomes slow and laborious ; and the juices no longer serving to convey their ac- customed nourishment, those parts may be said to live no longer when the circulation ceases. Thus the body dies by little and lit- tle ; all its functions are diminished by de- grees ; life is driven from one part of the frame to another; universal rigidity prevails; and death at last seizes upon the little that is left. As the bones, the cartilages, the muscles, and all other parts of the body, are softer in women than in men, these parts must, of con- sequence, require a longer time to come to that hardness which hastens death. Women, therefore, ought to be a longer time in grow- ing old than men; and this is actually the case. If we consult the tables which have been drawn up respecting human life, we shall find that, after a certain age, they are more long- lived than men, all other circumstances the same. A woman of sixty has a better chance than a man of the same age to live till eighty. Upon the whole, we may infer, that such per- sons as have been slow in coming up to ma- turity, will also be slow in growing old ; and this holds as well with regard to other ani- mals as to man. The whole duration of the life of either vegetables or animals, may be, in some measure, determined from their manner of coming to maturity. The tree, or the animal, which takes but a short time to increase to its utmost pitch, perishes much sooner than such as are less premature. In both the increase upwards is first accomplished ; and not till they have acquired their greatest degree of height do they b<>gin to spread in bulk. Man grows in stature till about the age of seventeen ; but his body is not completely develovedtillabout thirty. Dogs, on the other hand, are at their utmost size in a year, and become as bulky as they usually are in another. However, man, who is so long in growing, continues to live fourscore, or a hundred years; but the dog seldom above twelve or thirteen. In general, also, it may be said, that large animals live longer than little ones, as they usually take a longer time to grow. But in all animals, one thing is equally certain, that they carry the cause of their own decay about them ; and that their deaths are necessary and inevitable. The prospects which some visionaries have formed of perpetuating life by remedies, have been often enough prov- ed false by their own example. Such unac- countable schemes would, therefore, have died with them, had not the love of life always augmented our credulity. When the body is naturally well formed, it is possible to lengthen out the period of life for some years by management. Temperance in diet is often found conducive to this end. The famous Cornaro, who lived to above a hundred years, although his constitution was naturally feeble, is a strong instance of the benefit of an abstemious life. Moderation in the passions also may contribute to extend the term of our existence. " Fontenelle, the celebrated writer, was naturally of a very weak and delicate habit of body. He was affected by the small- est irregularities ; and had frequently suffered severe fits of illness from the slightest causes. But the remarkable equality of his temper, and ANIMALS. his seeming want of passion, lengthened out his life to above a hundred. It was re- markable of him, that nothing could vex or make him uneasy ; every occurrence seemed equally pleasing ; and no event, however un- fortunate, seemed to come unexpected." How- ever, the term of life can be prolonged but for a very little time by any art we can use. We are told of men who have lived beyond the ordinary duration of human existence; such as Parr, who lived to a hundred and forty-four ; and Jenkins, to a hundred and sixty-five ; yet these men used no peculiar arts to prolong life ; on the contrary, it appears that these, as well as others, remarkable for their longevity, were peasants accustomed to the greatest fatigues, who had no settled rules of diet, but who often indulged in accidental excesses. Indeed, if we consider that the European, the Negro, the Chinese, and the American, the civilized man and the savage, the rich and the poor, the in- habitant of the city and of the country, though all so different in other respects, are yet entirely similar in the period allotted them for living ; if we consider that neither the difference of race, of climate, of nourishment, of conveni- ence, or of soil, makes any difference in the term of life ; if we consider that those men who live upon raw flesh, or dried fishes, upon sago, or rice, upon cassava, or upon roots, nevertheless live as long as those who are fed upon bread and meat ; we shall readily be brought to acknowledge, that the duration of life depends neither upon habit, customs, or the quantity of food ; we shall confess, that no- thing can change the laws of that mechanism which regulates the number of our years, and \vhich can chiefly be affected only by long fast- ing, or great excess. If there be any difference in the different periods of man's existence, it ought principally to be ascribed to the quality of the air. It has been observed, that in elevated situations there have been found more old people than in those that were low. The mountains of Scotland, Wales, Auvergne, and Switzerland, have fur- nished more instances of extreme old age, than the plains of Holland, Flanders, Germany, or Poland. But, in general, the duration of life is nearly the same in most countries. Man, if not cut off by accidental diseases, is often found to live to ninety or a hundred years. Our ancestors did not live beyond that date : and, since the times of David, this term has under- gone little alteration. If we be asked, how in the beginning men lived so much longer than at present, and by what means their lives were extended to nine hundred and thirty, or even nine hundred and sixty years ; it may be answered, that the pro- ductions of the earth, upon which they fed, might be of a different nature at that time from what they are at present. " It may be answered, that the term was abridged by Di- vine command, in order to keep the earth from being overstocked with human inhabi- tants; since, if every person were now to live and generate for nine hundred years, mankind would be increased to such a degree, that there would be no room for subsistence : so that the plan of Providence would be altered ; which is seen not to produce life without pro- viding a proper supply." But to whatever extent life may be prolong- ed, or however some may have delayed the effects of age, death is the certain goal to Avhich all are hastening. All the causes of de- cay which have been mentioned contribute to bring on this dreaded dissolution. How- ever, nature approaches to this awful period by slow and imperceptible degrees; life is consumed day after day; and some one of our faculties, or vital principles, is every hour dying before the rest ; so that death is only the last shade in the picture ; and it is proba- ble that man suffers a greater change in going from youth to age, than from age into the grave. When we first begin to live, our lives may scarcely be said to be our own ; as the child grows, life increases in the same propor- tion ; and is at its height in the prime of man- hood. But as soon as the body begins to de- crease, life decreases also ; for as the human frame diminishes, and its juices circulate in smaller quantity, life diminishesand circulates with less vigour ; so that as we begin to live by degrees, we begin to die in the same man- ner. Why then should we fear death, if our lives have been such as not to make eternity dread- ful ? Why should we fear that moment, which is prepared by a thousand other moments of the same kind ? the first pangs of sickness be- ing probably greater than the last struggles of departure. Death, in most persons, is as 170 A HISTORY OP calmly endured as the disorder that brings it on. If we inquire from those whose business it is to attend the sick and the dying, we shall find that, except in a very few acute cases, where the patient dies in agonies, the greatest number die quietly, and seemingly without pain : and even the agonies of the former ra- ther terrify the spectators than torment the patient ; for how many have we not seen who have been accidentally relieved from this ex- tremity, and yet had no memory of what they then endured ? In fact, they had ceased to live during that time when they ceased to have sensation ; and their pains were only those of which they had an idea. The greatest number of mankind die, there- fore, without sensation ; arid of those few that still preserve their faculties entire to the last moment, there is scarcely one of them that does not also preserve the hopes of still out- living his disorder. Nature, for the happiness of man, has rendered this sentiment stronger than his reason. A person dying of an incu- rable disorder, which he must know to be so, by frequent examples of his case ; which he perceives to be so by the inquietude of all around him, by the tears of his friends, and the departure or the face of the physician, is, nevertheless, still in hopes of getting over it. His interest is so great, that he only attends to his own representations; the judgment of others is considered as a hasty conclusion ; and while death every moment makes new in- roads upon his constitution, and destroys life in some part, hope still seems to escape the universal ruin, and is the last that submits to the blow. Cast your eyes upon a sick man, who has a hundred times told you that he felt himself dying, ; .that he was convinced he could not recover, and that he was ready to expire; examine what passes on his visage, when, through zeal or indiscretion, any one comes to tell him that his end is at hand. You will see him change, like one who is told an un- expected piece of news. He now appears not to have thoroughly believed what he had been telling you himself: he doubted much ; and his fears were greater than his hopes ; but he still had some feeble expectations of living, and would not have seen the ap- proaches of death, unless he had been alarm- ed by the mistaken assiduity of his atten- dants. Death, therefore, is not that terrible thing which we suppose it to be. It is a spectre which frights us at a distance, but which dis- appears when we come to approach it more closely. Our ideas of its terrors are conceiv- ed in prejudice, and dressed up by fancy : we regard it not only as the greatest misfortune, but as also an evil accompanied with the most excruciating tortures ; we have even increas- ed our apprehensions, by reasoning on the extent of our sufferings. "It must be dread- ful," say some, " since it is sufficient to sepa- rate the soul from the body : it must be long, since our sufferings are proportioned to the succession of our ideas; and these being pain- ful, must succeed each other with extreme ra- pidity." In this manner has false philosophy laboured to augment the miseries of our na- ture ; and to aggravate that period which Na- ture has kindly covered with insensibility. Neither the mind nor the body can suffer these calamities : the mind is, at that time, mostly without ideas ; and the body too much enfee- bled to be capable of perceiving its pain. A very acute pain produces either death or fainting, which is a state similar to death : the body can suffer but to a certain degree ; if the torture become excessive, it destroys it- self; and the mind ceases to perceive, when the body can no longer endure. In this manner, excessive pain admits of no reflection : and wherever there are any signs of it, we may be sure that the sufferings of the patient are no greater than what we ourselves may have remembered to endure. But, in the article of death, we have many instances in which the dying person has shown that very reflection which presupposes an ab- sence of the greatest pain; and, consequently, that pang which ends life cannot even be so great as those which have preceded. Thus, when Charles XII. was shot at the siege of Frederickshall, he was seen to clap his hand on the hilt of his sword; and although the blow was great enough to terminate one of the boldest and bravest lives in the world, yet it was not painful enough to destroy re- flection. He perceived himself attacked ; he reflected that he ought to defend himself; and his body obeyed the impulse of his mind, ANIMALS. 177 even in the last extremity. Thus it is the prejudice of persons in health, and not the body in pain, that makes us suffer from the approach of death; we have all our lives con- tracted a habit of making out excessive plea- sures and pains ; arid nothing but repeated ex- perience shows us how seldom the one can be suffered, or the other enjoyed to the utmost. If there be any thing necessary to confirm what we have said concerning the gradual cessation of life, or the insensible approaches of our end, nothing can more effectually prove it than the uncertainty of the signs of death. If we consult what Winslow or Bruhier have said upon this subject, we shall be convinced, that between life and death the shade is so very undistinguishable, that even all the pow- ers of art can scarcely determine where the one ends, and the other begins. The colour of the visage, the warmth of the body, the sup- pleness of the joints, are but uncertain signs of life still subsisting ; while, on the contrary, the paleness of the complexion, the coldness of the body, the stiffness of the extremities, the cessation of all motion, and the total in- sensibility of the parts, are but uncertain marks of death begun. In the same manner, also, with regard to the pulse and the breath- ing, these motions are often so kept under, that it is impossible to perceive them. By ap- proaching a looking-glass to the mouth of the person supposed to be dead, people often ex- pect to find whether he breathes or not. But this is a very uncertain experiment : the glass is frequently sullied by the vapour of the dead man's body ; and often the person is still alive, although the glass is no way tarnished. In the same manner, neither burning nor scarifying, neither noises in the ears nor pun- gent spirits applied to the nostrils, give certain signs of the discontinuance of life ; and there are many instances of persons who have en- dured them all, and afterwards recovered without any external assistance, to the asto- nishment of the spectators. How careful, therefore, should we be, before we commit those w ho are dearest to us to the grave, to be well assured of their departure: experience, justice, humanity, all persuade us not to has- ten the funerals of our friends, but to keep their bodies unburied, until we have certain signs of their real decease. CHAPTER XXXIII. OF THE VARIETIES IN THE HUMAN RACE. HITHERTO we have compared man with other animals; we now come to compare men with each other. We have hitherto consider- ed him as an individual, endowed with ex- cellencies above the rest of the creation ; we now come to consider the advantages which men have over men, and the various kinds with which our earth is inhabited. If we compare the minute differences of mankind, there is scarce one nation upon the earth that entirely resembles another; and there may be said to be as many different kinds of men as there are countries inhabited. One polished nation does not differ more from another, than the merest savages do from those savages that lie even contiguous to them ; and it frequently happens that a river, or a mountain, divides two barbarous tribes that are unlike each other in manners, customs, features, and complexion. But these differ- ences,however perceivable, do not form such distinctions as come within a general picture of the varieties of mankind. Custom,accidcnt, or fashion, may produce considerable altera- tions in neighbouring nations ; their being derived from ancestors of a different climate, or complexion, may contribute to make acci- dental distinctions, which every day grow less; and it may be said, that two neighbouring nations, how unlike soever at first, will assimi- late by degrees ; and by long continuance, the difference between them will at last be- come almost imperceptible. It is not, there- fore, between contiguous nations we are to 178 A HISTORY OF look for any strong marked varieties in the human species: it is by comparing the in- habitants of opposite climates arid distant countries; those who live within the polar circles, with those beneath the equator; those that live on one side of the globe, with those that occupy the other. Of all animals, the differences between mankind are the smallest. Of the lower races of creatures, the changes are so great as often entirely to disguise the natural animal, and to distort, or to disfigure, its shape. But the chief differences in man are rather taken from the tincture of his skin than the variety of his figure : as in all climates he preserves his erect deportment, and the marked superiority of his form. If we look round the world, there seem to be not above six" distinct varie- ties in the human species, each of which is strongly marked, and speaks the kind seldom to have mixed with any other. But there is nothing in the shape, nothing in the faculties, that shows their coming from different origi- nals ; and the varieties of climate, of nourish- ment, and custom, are sufficient to produce every change. The first distinct race of men is found round the polar regions. The Laplanders, the Esquimaux Indians, the Samosid Tartars, the inhabitants of Nova Zembla, the Borandians, the Greenlanders, and the natives of Kamts- chatka, may be considered as one peculiar race of people, all greatly resembling each other in their stature, their complexion, their cus- toms, and their ignorance. These nations being under a rigorous climate, where the productions of nature are but few, and the provisions coarse and unwholesome, their bodies have shrunk to the nature of their food; and their complexions have suffered, from cold, almost a similar change to what heat is known to produce ; their colour being a deep brown, in some places inclining to actual blackness. These, therefore, in general, are found to be a race of short stature and odd shape, with countenances as savage as their manners are barbarous. The visage in these countries, is large and broad, the nose flat and short, the eyes of a yellowish brown, inclining I have taken four of these varieties from Linnteus; those of the Laplanders and Tartars from Mr. Buflbn. to blackness, the eye-lids drawn towards the temples, the cheek-bones extremely high, the mouth very large, the lips thick and turned outwards, the voice thin and squeaking, the head large, the hair black and straight, the colour of the skin of a dark grayish. b They are short in stature, the generality not being above four feet high, and the tallest not above five. Among all these nations the women are as deformed as the men, and resemble them so nearly, that one cannot at first distinguish the sexes among them. These nations not only resemble each other in their deformity, their dwarfishness, the colour of their hair and eyes, but they have, in a great measure, the same inclinations, and the same manners, being all equally rude, superstitious, and stupid. The Danish Lap- landers have a large black cat, to which they communicate their secrets, and consult in all their affairs. Among the Swedish Laplanders there is in every family a drum for consulting the devil ; and although these nations are robust and nimble, yet they are so cowardly that they never can be brought into the field. Gustavus Adolphus attempted to form a re- giment of Laplanders, but he found it impos- sible to accomplish his design; for it should seem that they can live only in their own country, and in their own manner. They make use of skates, which are made of fir, of near three feet long, and half a foot broad ; these are pointed, and raised before, and tied to the foot by straps of leather. With these they skate on the icy snow, and with such velocity, that they very easily overtake the swiftest animals. They make use also of a pole, pointed with iron at one end, and round- ed at the other. This pole serves to push them along, to direct their course, to support them from falling, to stop the impetuosity of their motion, and to kill that game which they have overtaken. Upon these skates they de- scend the steepest mountains, and scale the most craggy precipices ; and, in these exer- cises, the women are not less skilful than the men. They have all the use of the bow and arrow, which seems to be a contrivance com- mon to all barbarous nations ; and which, b Krantz. ANIMALS. 179 however, at first, required no small skill to in- vent. They launch a javelin, also, with great force, and some say, that they can hit a mark, no larger than a crown, at thirty yardsdistarice, and with such force as would pierce a man through. They are all hunters; and particu- larly pursue the ermine, the fox, the ounce, and the martin, for the sake of their skins. These they barter, with their southern neigh- bours, for brandy and tobacco ; both which they are fond of to excess. Their food is prin- cipally dried fish, the flesh of rein-deer and bears. Their bread is composed of the bones of fishes, pounded and mixed with the inside tender bark of the pine-tree. Their drink is train oil or brandy; and, when deprived of these, water, in which juniper berries have been infused. With regard to their morals, they have all the virtues of simplicity, and all the vices of ignorance. They offer their wives and daughters to strangers; and seem to think it a particular honour if their offer be accepted. They have no idea of religion, or a Supreme Being ; the greatest number of them are idolaters ; and their superstition is as profound as their worship is contemptible. Wretched and ignorant as they are, yet they do not want pride ; they set themselves far above the rest of mankind ; and Krantz as- sures us, that when the Greenlanders are got together, nothing is so customary among them as to turn the Europeans into ridicule. They are obliged, indeed, to yield them the pre- eminence in understanding and mechanic arts ; but they do not know how to set any value upon these. Th^y therefore count themselves the only civilized and well-bred people in the world ; and it is common with them, when they see a quiet or a modest stranger, to say that heisalmost as well bred asaGreenlander. From this description, therefore, this whole race of people may be considered as distinct from any other. Their long continuance in a climate the most inhospitable, their being ob- liged to subsist on food the most coarse and ill prepared, the savageness of their manners, and their laborious lives, all have contributed to shorten their stature, and to deform their bodies. 3 In proportion as we approach to- wards the north pole, the size of the natives Ellis's Voyage, p. 256. appears to diminish, growing less and less as we advance higher, till we come to those lati- tudes that are destitute of all inhabitants whatsoever. The wretched natives of these climates seem fitted by nature to endure the rigours of their situation. As their food is but scanty and precarious, their patience in hunger is amaz- ing." A man, who has eaten nothing for four days, can manage his little canoe in the most furious waves, and calmly-subsist in the midst of a tempest, that would quickly dash an Eu- ropean boat to pieces. Their strength is not less amazing than their patience ; a woman among them will carry a piece of timber, or a stone, near double the weight of what an European can lift. Their bodies are of a dark gray all over ; and their faces brown, or olive. The tincture of their skins partly seems to arise from their dirty manner of living, being generally daubed with train-oil; and partly from the rigours of climate, as the sudden al- terations of cold and raw air in winter, and of burning heats in summer, shade their com- plexions by degrees, till, in a succession of generations, they at last become almost black. As the countries in which they reside are the most barren, so the natives seem the most bar- barous of any part of the earth. Their more southern neighbours of America, treat them with the same scorn that a polished nation would treat a savage one ; and we may rea- dily judge of the rudeness of those manners, which even a native of Canada can think more barbarous than his own. But the gradations of nature are impercep- tible ; and, while the north is peopled with such miserable inhabitants, there are here and there to be found, upon the edges of these regions, people of a larger stature, and com- pleter figure. A whole race of the dwarfish breed is often found to come down from the north, and settle more to the southward ; and, on the contrary, it sometimes happens that southern nations are seen higher up, in the midst of these diminutive tribes, where they have continued for time immemorial. Thus the Ostiac Tartars seem to be a race that have travelled down from the north, and to be originally sprung from the minute savages b Krantz, p. 134. vol. i. 2K 180 A HISTORY OF we have been describing. There are also Norwegians andFinlanders, of proper stature, who are seen to inhabit in latitudes higher even than Lapland. These, however, are but accidental migrations, and serve as shades to unite the distinct varieties of mankind. The second great variety in the human spe- cies, seems to be that of the Tartar race ; from whence, probably, the little men we have been describing originally proceeded. The Tartar country, taken ingeneral.comprehends the greatest part of Asia ; and is, consequent- ly, a general name given to a number of nati- ons, of various forms and complexions. But, however they seem to differ from each other, they all agree in being very unlike the people of any other country. All these nations have the upper part of the visage very broad, and wrinkledevenwhile yet in their youth. Their noses are short and flat, their eyes little, and sunk in their heads ; and, in some of them, they are seen five or six inches asunder. Their cheek-bones are high, the lower part of their visage narrow, the chin long and ad- vanced forward, their teeth of an enormous size, and growing separate from each other; their eyebrows thick, large, and covering their eyes ; their eyelids thick, the face broad and flat, the complexion olive coloured, and the hair black. They are of a middle size, extremely strong, and very robust. They have but little beard, which grows straggling on the chin. They have large thighs, and short legs. The ugliest of all are the Cal- mucks, in whose appearance there seems to be something frightful. They all lead an er- ratic life, remaining under tents of hair, or skins. They live upon horse flesh, and that of camels, either raw or a little sodden be- tween the horse and the saddle. They eat also fish dried in the sun. Their most usual drink is ^.lares' milk, fermented with millet ground into meal. They all have the head shaven, except a lock of hair on the top, which they let grow sufficiently long to form into tresses, on each side of the face. The women, who are as ugly as the men, wear their hair, which they bind up with bits of copper, and other ornaments of a like nature. The majority of these nations have no religi- on, no settled notions of morality, no decency of behaviour. They are chiefly robbers; and the natives of Dagestan, who live near their more polished neighbours, make a traf- fic of Tartar slaves who have been stolen, and sell them to the Turks and the Persians.. Their chief riches consist in horses, of which perhaps there are more in Tartary than in any other part of the world. The natives are taught by custom to live in the same place with their horses, they are continually em- ployed in managing them, and at last bring them to such great obedience, that the horse seems actually to understand the riders inten- tion. To this race of men, also, we must refer the Chinese and the Japanese, however dif- ferent they seem in their manners and cere- monies. It is the form of the body that we are now principally considering ; and there is, between these countries, a surprising resem- blance. It is in general allowed, that the Chinese have broad faces, small eyes, flat noses, and scarce any beard ; that they are broad and square shouldered, and rather less in stature than Europeans. These are marks common to them and the Tartars, and they may, therefore, be considered as being deriv- ed from the same original. " I have observ- ed," says Chardin, " that in all the people from the east and the north of the Caspian sea, to the peninsula of Malacca, that the lines of the face, and the formation of the visage, is the same. This has induced me to believe, that all these nations are derived from the same original, however different either their complexions or their manners may appear : for as to the complexion, that proceeds entire- ly from the climate and the food ; and as to the manners, these are generally the result of their different degrees of wealth or power." That they come from one stock, is evident also from this, that the Tartars who settle in China, quickly resemble the Chinese ; and, on the contrary, the Chinese who settle in Tartary, soon assume the figure and the man- ners of the Tartars. The Japanese so much resemble the Chi- nese, that one cannot hesitate to rank them in the same class. They only differ in being rather browner, as they inhabit a more south- ern climate. They are, in general, described as of a brown complexion, a short stature, a broad flat face, a very little beard, and black ANIMALS. 181 hair. Their customs and ceremonies are nearly the same ; their ideas of beauty simi- lar; and their artificial deformities of black- ening the teeth, and bandaging the feet, en- tirely alike in both countries. They both, therefore, proceed from the same stock ; and although they differ very much from their bru- tal progenitors, yet they owe their civiliza- tion wholly to the mildness of the climate in which they reside, and to the peculiar fertili- ty of the soil. To this tribe, also, we may re- fer the Cochin Chinese, the Siamese, the Ton- quinese, and the inhabitants of Arracan, Laos, and Pegu, who, though all differing from the Chinese and each other, nevertheless have too strong a resemblance not to betray their common original. Another, which makes the third variety in the human species, is, that of the southern Asiatics ; the form of whose features and per- sons may be easily distinguished from those of the Tartar races. The nations that inha- bit the peninsula of India, seem to be the prin- cipal stock from whence the inhabitants of the islands that lie scattered in the Indian ocean have been peopled. They are, in general, of a slender shape, with long straight black hair, and often with Roman noses. Thus they re- semble the Europeans i.-i stature and features; but greatly differ in colour and habit of body. The Indians are of an olive colour, and, in | the more southern parts, quite black ; al- though the word Mogul, in their language, sig- nifies a white man. The women are extreme- ly delicate, and bathe very often; they are of an olive colour, as well as the men: their legs and thighs are long, and their bodies short, which is the opposite to what is seen among the women of Europe. They are, as I am assured, by no means so fruitful as the European women ; but they feel the pains of child-birth with much less sensibility, and are generally up and well the day following. In fact, these pains seem greatest in all coun- tries where the women are most delicate, or the constitution enfeebled by luxury or indo- lence. The women of savage nations seem, in a great measure, exempt from painful la- bours; and even the hard-working wives of the peasants among ourselves, have this ad- vantage from a life of industry, that their child- bearing is less painful. Over all India, the children arrive sooner at maturity, than with us of Europe. They often marry and consum- mate, the husband at ten years old, and the wife at eight ; and they frequently have chil- dren at that age. However, the women who arc mothers so soon, cease bearing before they are arrived at thirty ; and at that time they appear wrinkled, and seem marked with all the deformities of age. The Indians have long been remarkable for their cowardice and effeminacy ; every conqueror, that has at- tempted the invasion of their country, having succeeded. The warmth of the climate en- tirely influences their manners ; they are slothful, submissive, and luxurious; satisfied with sensual happiness alone, they find no pleasure in thinking ; and contented with sla- very, they are ready to obey any master. Many tribes among them eat nothing that has life ; they are fearful of killing the meanest in- sect ; and have even erected hospitals for the maintenance of all kinds of vermin. The Asiatic dress is a loose flowing garment, ra- ther fitted for the purposes of peace and in- dolence, than of industry or war. The vi- gour of the Asiatics is, in general, conformable to their dress and nourishment; fed upon rice, and clothed in effeminate silk vestments, their soldiers are unable to oppose the onset of an European army ; and from the times of Alex- ander to the present day, we have scarcely any instances of their success in arms. Upon the whole, therefore, they may be considered as a feeble race of sensualists, too dull to find rapture in any pleasures, and too indolent to turn their gravity into wisdom. To this class we may refer the Persians, and Arabians, and, in general, the inhabitants of the islands that lie scattered in the Indian ocean. The fourth striking variety in the human species, is to be found among the negroes of Africa. This gloomy race of mankind is found to blacken all the southern parts of Africa, from eighteen degrees north of the line, to its extreme termination at the Cape of Good Hope. I know it is said, that the Caff'res, who inhabit the southern extremity of that large continent, are not to be ranked among the negro race : however, the difference be- tween them, in point of colour and features, is so small, that they may very easily be group- ed in this general picture; and in the one or 2K* 182 A HISTORY OP two that I have seen, I could not perceive the smallest difference. Each of the negro nati- ons, it must be owned, differ from each other; they have their peculiar countries for beauty, like us ; and different nations, as in Europe, pride themselves upon the regularity of their features. Those of Guinea, for instance, are extremely ugly, and have an insupportable scent ; those of Mosambique are reckoned beautiful, and have no ill smell whatsoever. The negroes, in general, are of a black colour, with a smooth soft skin. This smoothness proceeds from the downy softness of the hair which grows upon it; the strength of which gives aroughnessto the feel, in those of a white complexion. Their skins, therefore, have a velvet smoothness, and seem less braced up- on the muscles than ours. The hair of their h; ads differs entirely from what we are ac- customed to, being soft, woolly, and short. The beard also, partakes of the same qualities ; but in this it differs, that it soon turns gray, which the hair is seldom found to do ; so that several are seen with white beards, and black hair, at the same time. Their eyes are gene- rally of a deep hazel ; their noses flat and short; their lips thick and tumid; and their teeth of an ivory whiteness. This, their only beauty, however, is set off by the colour of their skin ; the contrast between the black and white being the more observable. It is false to say that their features are deformed by art ; since, in the negro children born in European countries, the same deformities are seen to prevail ; the same flatness in the nose; and the same prominence in the lips. They are, in general, said to be well shaped ; but of such as I have seen, I never found one that might be justly called so; their legs being mostly ill formed, and commonly bending out- ward on the shin-bone. But it is not only in those parts of their bodies that are obvious, that they are disproportioned ; those parts which among us are usually concealed by dress, with them are large an*languid. a The women's breasts, after bearing one child, hang down below the navel ; and it is customary with them to suckle the child at their backs, by throwing the breasts over the shoulder. a LiniHEiis, in prinia lines sna, faeminas Af'ricanas de- pingit sicut aliquid defomie in parte genital! gestaiites, quod sinum pudoris nuncupat. Attamen nihil differunt a As their persons are thus naturally deformed, at least to our imaginations, their minds are equally incapable of strong exertions. The climate seems to relax their mental powers still more than those of the body ; they are, therefore, in general, found to be stupid, in- dolent, and mischievous. The Arabians them- selves, many colonies of whom have migrated southward into the most inland parts of Africa, seem to have degenerated from their ances- tors ; forgetting their ancient learning, and losing their beauty, they have become a race scarcely any way distinguishable from the original natives. Nor does it seem to have fared otherwise with the Portuguese, who about two centuries ago, settled along this coast. They also are become almost as black as the negroes, and are said by some to be even more barbarous. The inhabitants of America make a fifth race, as different from all the rest in colour, as they are distinct in habitation. The natives of America (except in the northern extremity, where they resemble the Laplanders) are of a red or copper colour; and although, in the old world, different climates produce a variety of complexions and customs, the natives of the new continent seem to resemble each other in almost every respect. They are all nearly of one colour; all have black thick straight hair, and thin black beards ; which, however, they take care to pluck out by the roots. They have, in general, flat noses, with high cheek-bones, and small eyes ; and these de- formities of nature they endeavour to increase by art : they flatten the nose, and often the whole head of their children, while the bones are yet susceptible of every impression. They paint the body and face of various colours, and consider the hair upon any part of it, ex- cept the head, as a deformity which they are careful to eradicate. Their limbs are gene- rally slighter made than those of the Euro- peans ; and, I am assured, they are far from being so strong. All these savages seem to be cowardly; they seldom are known to face their enemies in the field, but fall upon them at an advantage ; and the greatness of their fears serves to increase the rigours of their nostratibus in hac parte nisi quod labia pudendae sint ali- qriantulum tuniidiora. In hominibus etiam penis est lon- gior et multo laxior. ANIMALS. 183 Cruelty. The wants which they often sustain, make them surprisingly patient in adversity : distress, by being grown familiar, becomes less terrible ; so that their patience is less the result of fortitude than of custom. They have all a serious air, although they seldom think; and, however cruel to their enemies, are kind and just to each other. In short, the customs of savage nations in every country are almost the same; a wild, independent, and preca- rious life, produces a peculiar train of virtues and vices : and patience and hospitality, in- dolence and rapacity, content and sincerity, are found not less among the natives of America, than all the barbarous nations of the globe. The sixth and last variety of the human species, is that of the Europeans, and the nations bordering on them. In this class we may reckon the Georgians, Circassians, and Mingrelians, the inhabitants of Asia Minor, and the northern parts of Africa, together with a part of those countries which lie north- west of the Caspian sea. The inhabitants of these countries differ a good deal from each other; but they generally agree in the colour of their bodies, the beauty of their complex- ions, the largeness of their limbs, and the vigour of their understandings. Those arts which might have had their invention among the other races of mankind, have come to perfection there. In barbarous countries the inhabitants go either naked, or are awkwardly clothed in furs or feathers; in countries semi- barbarous, the robes are loose and flowing; but here the clothing is less made for show than expedition, and unites, as much as pos- sible, the extremes of ornament and despatch. To one or other of these classes we may refer the people of every country: and as each nation has been less visited by strangers, or has had less commerce with the rest of man- kind, we find their persons and their manners more strongly impressed with one or other of the characters mentioned above. On the contrary, in those places where trade has long flourished, or where enemies have made many incursions, the races are usually found blended, and properly fall beneath no one character. Thus, in the islands of the Indian ocean, where a trade has been carried on for time immemorial, the inhabitants appear to be a mixture of all the nations upon the earth; white, olive, brown, and black men, are all seen living together in the same city, and pro- pagate a mixed breed, that can be referred to none of the classes into which naturalists have thought proper to divide mankind. Of all the colours by which mankind is diversified, it is easy to perceive, that ours is not only most beautiful to the eye, but the most advantageous. The fair complexion seems, if I may so express it, as a transparent covering to the soul ; all the variations of the passions, every expression of joy or sorrow, flows to the cheek, and, without language, marks the mind. In the slightest change of health also the colour of the European face is the most exact index, and often teaches us to prevent those disorders that we do not as yet perceive : not but that the African black, and the Asiatic olive complexions, admit of their alterations also ; but these are neither so distinct, nor so visible, as with us; and in some countries the colour of the visage is never found to change; but the face continues in the same settled shade in shame and in sick- ness, in anger and despair. The colour, therefore, most natural toman, ought to be that which is most becoming; and it is found, that, in all regions, the children are born fair, or at least red, and that they grow more black, or tawny, as they advance in age. It should seem, consequently, that man is naturally white; since the same causes that darken the complexion in infants, may have originally operated, in slower degrees, in blackening whole nations. We could, therefore, readily account for the blackness of different nations, did we not seethe Ameri- cans, who live under the line, as well as the natives of Negroland, of a red colour, and but a very small shade darker than the natives of the northern latitudes, in the same continent. For this reason, some have sought for other causes of blackness than the climate ; and have endeavoured to prove that the blacks are a race of people bred from one man, who was marked with accidental blackness. This, however, is but mere ungrounded conjecture : and, although the Americans are not so dark as the negroes, yet we must still continue in the ancient opinion, that the deepness of the colour proceeds from the excessive heat of 184 A HISTORY OF the climate. For, if we compare the heats of Africa with those of America, we shall find they bear no proportion to each other. In America, all that part of the continent, which lies under the line, is cool and pleasant, either shaded by mountains, or refreshed by breezes from the sea. But in Africa, the wide tract of country that lies under the line is very ex- tensive, and the soil sandy ; the reflection of the sun, therefore, from so large a surface of earth, is almost intolerable ; and it is not to be wondered at, that the inhabitants should bear, in their looks, the marks of the inhos- pitable climate. In America, the country is out thinly inhabited; and the more torrid tracts are generally left desert by the inhabitants; for which reason they are not so deeply tinged by the beams of the sun. But in Africa the whole face of the country is fully peopled ; and the natives are obliged to endure their situation, without a power of migration. It is there, consequently, that they are in a man- ner tied down to feel all the severity of the heat ; and their complexions take the darkest hue they are capable of receiving. We need not, therefore, have recourse to any imagina- ry propagation, from persons accidentally black, since the climate is a cause obvious and sufficient to produce the effect. In fact, if we examine the complexion of dif- ferent countries, we shall find them darken in proportion to the heat of their climate ; and the shades gradually to deepen as they ap- proach the line. Some nations, indeed, may be found not so much tinged by the sun as others, although they lie nearer the line. But this ever proceeds from some accidental causes ; either from the country lying higher, and consequently being colder ; or from the natives bathing oftener, and leading a more civilized life. In general, it may be asserted, that as we approach the line, we find the in- habitants of each country grow browner, un- til the colour deepens into perfect blackness. Thus, taking our standard from the whitest race of people, and beginning with our own country, which, I believe, bids fairest for the pre-eminence, we shall find the French, who are more southern, a slight shade deeper than we; going farther down, the Spaniards are browner than the French; the inhabitants of Fez darker than they ; and the natives of Ne- groland the darkest of all In what manner the sun produces this effect, and how thesame luminary which whitens wax and linen, should darken the human complexion, is not easy to conceive. Sir Thomas Brown first supposed, that a mucous substance, which had some- thing of a vitriolic quality, settled under the reticular membrane, and grew darker with heat. Others have supposed that the black- ness lay in the epidermis, or scarf-skin, which was burnt up like leather. But nothing has been satisfactorily discovered upon the sub- ject ; it is sufficient that we are assured of the fact ; and that we have no doubt of the sun's tinging the complexion in proportion to its vicinity. But we are not to suppose that the sun is the only cause of darkening the skin ; the wind, extreme cold, hard labour, or coarse and sparing nourishment, are all found to con- tribute to this effect. We find the peasants of every country, who are most exposed to the weather, a shade darker than the higher ranks of people. The savage inhabitants of all pla- ces are exposed still more, and therefore con- tract a still deeper hue ; and this will account for the tawny colour of the North American Indians. Although they live in a climate the same, or even more northerly than ours, yet they are found to be of complexions very dif- ferent from those of Europe. But it must be considered, that they live continually exposed to the sun ; that they use many methods to darken their skins by art, painting them with red ochre, and anointing them with the fat of bears. Had they taken, for a succession of several generations, the same precautions to brighten their colour that an European does, it is very probable that they would in time come to have similar complexions, and, per- haps, dispute the prize of beauty. The extremity of coll is not less produc- tive of a tawny complexion than that of heat. The natives of the arctic circle, as was ob- served, are all brown ; and those that lie most to the north are almost entirely black. In this manner both extremes are unfavoura- ble to the human tbrm and colour, and the same effects are produced under the poles that are found at the line. With regard to the slature of different countries, that seems chielly to result from the ANIMALS. 183 nature of the food, and the quantity of the supply. Not but that the severity of heat or cold, may, in some measure, diminish the growth, and produce adwarfishness of make. But, in general, the food is the great agent in producing this effect ; where that is supplied in large quantities, and where its quality is wholesome and nutrimental, the inhabitants are generally seen above the ordinary stature. On the contrary, where it is afforded in a sparing quantity, or very coarse, and void of nourishment in its kind, the inhabitants de- generate, and sink below the ordinary size of mankind. In this respect they resemble other animals, whose bodies, by proper feeding, may be greatly augmented. An ox, on the fertile plains of India, grows to a size four times as large as the diminutive animal of the same kind bred in the Alps. The horses bred in the plains are larger than those of the mountain. So it is with man ; the inhabitants of the valley are usually found taller than those of the hill; the natives of the Highlands of Scotland, for instance, are short, broad, and hardy ; those of the Lowlands are tall and shapely. The inhabitants of Greenland, who live upon dried fish and seals, are less than those of Gambia, or Senegal, where Nature supplies them with vegetable and animal abundance. The form of the face seems rather to be the result of custom. Nations who have long considered some artificial deformity as beau- tiful, who have industriously lessened the feet, or flattened the nose, by degrees begin to re- ceive the impression they are taught to as- sume ; and Nature, in a course of ages, shapes itself to the constraint, and assumes heredita- ry deformity. We find nothing more com- mon in births, than for children to inherit sometimes even the accidental deformities of their parents. We have many instances of squinting in thefather,which he received from fright or habit, communicated to the offspring; and I myself have seen a child distinctly mark- ed with a scar, similar to one the father had received in battle. In this manner, acciden- tal deformities may become natural ones ; and by assiduity may be continued, and even in- creased, through successivegenerations. From this, therefore, may have arisen the small eyes and long ears of the Tartar and Chinese na- tions. From hence originally may have come the flat noses of the blacks, and the flat heads of the American Indians. In this slight survey, therefore, I think we may see that all the variations in the human figure, as far as they differ from our own, are produced either by the rigour ol the climate, the bad quality or the scantiness of the pro- visions, or by the savage customs of the coun- try. They are actual marks of the degenera- cy in the human form ; and we may consider the European figure and colour as standards to which to refer all other varieties, and with which to compare them. In proportion as the Tartar or American approaches nearer to Eu- ropean beauty, we consider the race as less degenerated ; in proportion as he differs more widely, he has made greater deviations from his original form. That we have all sprung from one common j parent we are taught, both by reason and re- ! ligion, to believe ; and we have good reason also to think that the Europeans resemble him more than any of the rest of his children. However, it must not be concealed that the olive-coloured Asiatic, and even the jet-black negro, claim this honour of hereditary resem- blance ; and assert, that white men are mere deviations from original perfection. Odd as this opinion may seem, they have Linnaeus, the celebrated naturalist, on their side ; who supposes man a native of the tropicnl climates, and only a sojourner more to the north. But, not to enter into a controversy upon a matter of a very remote speculation, I think one ar- gument alone will suffice to prove the contra- ry, and show that the white man is the origi- nal source from whence the other varieties have sprung. We have frequently seen white children produced from black parents, but have never seen a black offspring the produc- tion of two whites. From hence we may con- clude, that whiteness is the colour to which mankind naturally tends : for, as in the tulip, the parent stock is known by all the artificial varieties breaking into it ; so in man, that co- lour must be original which never alters, and to which all the rest are accidentally seen to change. I have seen in London, at different times, two white negroes, the issue of black parents, that served to convince me of the truth of this theory. I had before been taught 180 A HISTORY OF to believe that the whiteness of the negro's skin was a disease, a kind of milky whiteness, that might be called rather a leprous crust than a natural complexion. I was taught to suppose, that the numberless white negroes found in various parts of Africa, the white men that go by the name of Chacrelas, hi the East Indies, and the white Americans, near the Isthmus of Darien, in the West Indies, were all as so many diseased persons, and even more deformed than the blackest of the natives. But, upon exa- mining that negro which was last shown in London, 1 found the colour to be exactly like that of an European; the visage white and ruddy, and the lips of the proper redness. How- ever, there were sufficient marks to convince me of its descent. The hair was white and woolly, and very unlike any thing I had seen before. The iris of the eye was yellow, inclin- ing to red ; the nose was flat, exactly resem- bling that of a negro ; and the lips thick and prominent. No doubt, therefore, remained of the child's having been born of negro parents : and the person who showed it had attestations to convince the most incredulous. From this, then, we see that the variations of the negro colour is into whiteness, whereas the white are never found to have a race of negro children. Upon the whole, therefore, all those changes which the African, the Asiatic,orthe American, undergo, are but accidental deformities, which a kinder climate, better nourishment, or more civilized manners, would, in a course of cen- turies, very probably remove. CHAPTER XXXIV. OF MONSTERS. HITHERTO I have only spoken of those \ r arieties in the human species, that are com- mon to whole nations ; but there are varieties of another kind, which are only found in the individual ; and being more rarely seen, are therefore called monstrous. If we examine into the varieties of distorted nature, there is scarcely a limb of the body, or a feature in the face, that has not suffered some reprobation, either from art or nature ; being enlarged or diminished, lengthened or wrested, from its due proportion. Linnaeus, after having given a catalogue of monsters, particularly adds, the flat heads of Canada, the long heads of the Chinese, and the slender waists of the women of Europe, who, by strait lacing, take such pains to destroy their health, through a mis- taken desire to improve their beauty. 3 It be- a Linnaei Syst. vol. i. p. 29.

Some, however, are fond of such accounts ; and there have been books filled with nothing else. To these, therefore, I refer the reader ; who may be better pleased with accounts of men with two heads, or with- out any head, of children joined in the middle, of bones turned into flesh, or flesh converted into bones, than I am. b It is sufficient here to observe, that every day's experience must have shown us miserable instances of this kind produced by nature or affectation; cala- milities that no pity can soften, or assiduity relieve. rum dente aureo, alter cum capite giganteo Bilupe specta- bantur.

In short, the variety of these accounts is almost infinite ; and, perhaps, their use is as much cir- cumscribed as their variety is extensive ANIMALS 187 Passing over, therefore, every other ac- count, I shall only mention the famous instance quoted by Father Malbranche, upon which- he founds his beautiful theory of monstrous productions. A woman of Paris, the wife of n tradesman, went to see a criminal broke alive upon the wheel, at the place of public execution. She was at that time two months advanced in her pregnancy, and no way sub- ject to any disorders to affect the child in her womb. She was, however, of a tender habit of body ; and, though led by curiosity to this horrid spectacle, very easily moved to pity and compassion. She felt, therefore, all those strong emotions which so terrible a sight must naturally inspire ; shuddered at every blow the criminal received, and almost swooned at his cries. Upon returning from this scene of blood, she continued for some days pensive, and her imagination still wrought upon the spectacle she had lately seen. After some timc,however,sheseemed perfectly recovered from her fright, and had almost forgotten her former uneasiness. When the time of her de- livery approached, she seemed no ways mind- ful of her former terrors, nor were her pains in labour more than usual in such circumstan- But what was the amazement of her ces. friends and assistants when the child came into the world ! It was found that every limb in its body was broken like those of the male- factor, and just in the same place. This poor infant, that had suffered the pains of life even before its coming into the world, did not die, but lived in an hospital in Paris, for twenty years after, a wretched instance of the sup- posed powers of imagination in the mother, of altering and distorting the infant in the womb. The manner in which Malbranche reasons upon this fact, is as follows: the Creator has established such a sympathy between the se- veral parts of nature, that we are led not only to imitate each other, but also to partake in the same affections and desires. The animal spirits are thus carried to the respective parts of the body, to perform the same actions which we see others perform, to receive in tome measure their wounds, and take part in their sufferings. Experience tells us, that if wo look attentively on any person severely beaten, or sorely wounded, the spirits imme- diately flow into those parts of the body which NO. 17 & 18. correspond to those we see in pain. The more delicate the constitution, the more it is thus affected ; the spirits making a stronger impression on the fibres of a weakly habit than of a robust one. Strong vigorous men see an execution without much concern, while women of nicer texture are struck with hor- ror and concern. This sensibility in them must, of consequence, be communicated to all parts of their body; and as the fibres of the child in the womb are incomparably finer than those of the mother, the course of the animal spirits must consequently produce greater alterations. Hence, every stroke giv- en to the criminal forcibly struck the imagi- nation of the woman ; and, by a kind of coun- ter-stroke, the delicate tender frame of the child. Such is the reasoning of an ingenious man upon a fact, the veracity of which many have since called in question.' They have allow- ed, indeed, that such a child might have been produced, but have denied the cause of its deformity. " How could the imagination of the mother," say they, " produce such dread- ful effects upon her child ? She has no com- munication with the infant ; she scarcely touches it in any part ; quite unaffected with her concerns, it sleeps in security, in a man- ner secluded by a fluid in which it swims, from her that bears it. With what a variety of deformities," say they, "would all man- kind be marked, if all the vain and caprici- ous desires of the mother were thus readily written upon the body of the child !" Yet, notwithstanding this plausible way of reason- ing, I cannot avoid giving some credit to the variety of instances I have either read or seen upon this subject. If it be a prejudice, it is as old as the days of Aristotle, and to this day as strongly believed by the generality of man- kind as ever. It does not admit of a reason; and, indeed, I can give none, even why the child should, in any respect, resemble the fa- ther or the mother. The fact we generally find to be so. But why it should take the par- ticular print of the father's features in the womb is as hard to conceive, as why it should be effected by the mother's imagination. We all know what a strong effect the imagination Billion, vol iv. p. 9. 2L 188 A HISTORY OF has on those parts in particular, without being able to assign a cause how this effect is pro- duced ; and why the imagination may not produce the same effect in marking the child that it does in forming it, I see no reason. Those persons whose employment it is to rear up pigeons of different colours can breed them, as their expression is, to a feather. In fact, by properly pairing them, they can give what colour they will to any feather, in any part of the body. Were we to reason upon this fact, what could we say ? Might it not be asserted, that the egg, being distinct from the body of the female, cannot be influenced by it ? Might it not be plausibly said, that there is no similitude between any part of the egg and any particular feather which we ex- pect to propagate ; and yet, for all this, the tact is known to be true, and what no specu- lation can invalidate. In the same manner, a thousand various instances assure us, that the child in the womb is sometimes marked by the strong affections of the mother : how this is performed we know not ; we only see the effect, without any connection between it and the cause. The best physicians have al- lowed it; and have been satisfied to submit to the experience of a number of ages ; but many disbelieve it, because they expect a reason for every effect. This, however, is very hard to be given, while it is very easy to appear wise by pretending incredulity. Among the number of monsters, dwarfs and giants are usually reckoned ; though not, per- haps, with the strictest propriety, since they are no way different from the rest of mankind, except in stature. It is a dispute, however, about words; and, therefore, scarcely worth contending about. But there is a dispute, of a more curious nature, on this subject ; name- ly, whether there are races of people thus very diminutive, or vastly large; or whether they be merely accidental varieties, that now and then are seen in a country, in a few per- sons, whose bodies some external cause has contributed to lessen or enlarge. With regard to men of diminutive stature, all antiquity has been unanimous in asserting their national existence. Homer was the first who has given us an account of the pigmy na- tion contending with the cranes; and what poetical license might be supposed to exag- gerate, Athenseus has attempted seriously to confirm by historical assertion." If we attend to these, we must believe that, in the internal parts of Africa, there are whole nations of pig- my beings, not more than a foot in stature, who continually wage an unequal war with the birds and beasts that inhabit the plains in which they reside. Some of the ancients, however, and Strabo in particular, have sup- posed all these accounts to be fabulous ; and have been more inclined to think this suppos- ed nation of pigmies nothing more than a spe- cies of apes, well known to be numerous in that part of the world. With this opinion the moderns have all concurred ; and that dimi- nutive race, which was described as human, has been long degraded into a class of ani- mals that resemble us but very imperfectly. The existence, therefore, of a pigmy race of mankind being founded in error, or in fable, we can expect to find men of diminutive sta- ture only by accident, among men of the or- dinary size. Of these accidental dwarfs, every country, and almost every village, can produce numerous instances. There was a time when these unfavoured children of Na- ture were the peculiar favourites of the great ; and no prince or nobleman thought himself completely attended unless he had a dwarf among the number of his domestics. These poor little men were kept to be laughed at ; or to raise the barbarous pleasure of their masters, by their contrasted inferiority. Even in England, as late as the times of King James I. the court was at one time furnished with a dwarf, a giant, and a jester ; these the king often took a pleasure in opposing to each other, and often fomented quarrels among them, in order to be a concealed spectator of their animosity. It was a particular entertain- ment of the courtiers at that time to see little Jeffrey, for so the dwarf was called, ride round the lists, expecting his antagonist; and dis- covering, in his actions, all the marks of con- temptible resolution. It was in the same spirit, that Peter of Rus- sia, in the year 1710, celebrated a marriage of dwarfs. This monarch, though raised by his native genius far above a barbarian, was, nevertheless, still many degrees removed from Athenaeus, ix. 390. \NIMALS. 189 actual refinement. His pleasures, therefore, were of the vulgar kind ; and this was among the number. Upon a certain day, which he had ordered to be proclaimed several months before, he invited the whole body of his cour- tiers, and all the foreign ambassadors, to be present at the marriage of a pigmy man and woman. The preparations for this wedding were not only very grand, but executed in a style of barbarous ridicule. He ordered that all the dwarf men and women, within two hundred miles, should repair to the capital ; and also insisted that they should be present at the ceremony. For this purpose he sup- plied them with proper vehicles ; but so con- trived it, that one horse was seen carrying in a dozen of them into the city at once, while the mob followed, shouting and laughing, from behind. Some of them were at first un- willing to obey an order which they knew was calculated to turn them into ridicule, and did not come : but he soon obliged them to obey ; and, as a punishment, enjoined, that they should wait upon the rest at dinner. The whole company of dwarfs amounted to seven- ty, besides the bride and bridegroom, who were richly adorned, and in the extremity of the fashion. For this little company in mini- ature, every thing was suitably provided ; a low table, small plates, little glasses, and, in short, every thing was so fitted as if all things had been dwindled to their own standard. It was his great pleasure to see their gravity and their pride ; the contention of the women for places, and the men for superiority. This point he attempted to adjust, by ordering that the most diminutive should take the lead ; but this bred disputes, for none would then con- sent to sit foremost. All this, however, being at last settled, dancing followed the dinner, and the ball was opened with a minuet by the bridegroom, who measured exactly three feet two inches high. In the end, matters were so contrived, that this little company, who met together in gloomy pride, and unwilling to be pleased, being at last familiarized to laughter, joined in the diversion, and became, as the journalist has it,' extremely sprightly and en- tertaining. Die dench wurdige. Iwerg. Hockweit, &c. Lipsia-, 1713, vol. viii. p. 102. seq. But whatever may be the entertainment such guests might afford when united, I never found a dwarf capable of affording any when alone. I have sometimes conversed with some of these that were exhibited at our fairs about Town, and have ever found their intellects as contracted as their persons. They, in gene- ral, seemed to me to have faculties very much resembling those of children, and their desires likewise of the same kind ; being diverted with the same sports, and best pleased with such companions. Of all those I have seen, which may amount to five or six, the little man, whose name was Coan, that died lately at Chelsea, was the most intelligent and sprightly. I have heard him and the giant, who snug at the theatres, sustain a very ridiculous duct, to which they were taught to give great spirit. But this mirth, and seeming sagacity, were but assumed. He had, by long habit, been taught to look cheerful upon the approach of company ; and his conversation was but the mere etiquette of a person that had been used to receive visiters. When driven out of his walk, nothing could be more stupid or igno- rant, nothing more dejected or forlorn. But we have a complete history of a dwarf, very accurately related by Mr. Daubenton, in his part of the Histoire Naturelle ; which I will here take leave to translate. This dwarf, whose name was Baby, was well known, having spent the greatest part of his life at Lunenville, in the palace of Sta- nislaus, the titular king of Poland. He was born near the village of Plaisne, in France, in the year 1741. His father and mother were peasants, both of good constitutions, and inured to a life of husbandry and labour. Baby, when born, weighed but a pound and a quar- ter. We are not informed of the dimensions of his body at that time ; but we may conjec- ture they were very small, as he was present- ed on a plate to be baptized, and for a long time lay in a slipper. His mouth, although proportioned to the rest of his body, was not, at that time, large enough to take in the nip- ple; and he was, therefore, obliged to be suck- led by a she-goat that was in the house ; and that served as a nurse, attending to his cries with a kind of maternal fondness. He began to articulate some words when eighteen months old ; and at two vears he was able to walk 2L* 190 A HISTORY OF alone. He was then fitted with shoes that were about an inch and a half long. He was attacked with several acute disorders; but the small-pox was the only one which left any marks behind it. Until he was six years old, he eat no other food but pulse, potatoes, and bacon. His father and mother were, from their poverty, incapable of affording him any better nourishment ; and his education was little better than his food, being bred up among the rustics of the place. At six years old he was about fifteen inches high ; and his whole body weighed but thirteen pounds. Notwithstanding this, he was well proportion- ed, and handsome ; his health Avas good, but his understanding scarcely passed tlie bounds of instinct. It was at that time that the king of Poland, having heard of such a curiosity, had him conveyed to Lunenville, gave him the name of Baby, and kept him in his palace. Baby, having thus quitted the hard conditi- on of a peasant, to enjoy all the comforts and conveniences of life, seemed to receive no al- teration from his new way of living, either in mind or person. He preserved the goodness of his constitution till about the age of sixteen, but his body seemed to increase very slowly during the whole time ; and his stupidity was such, that all instructions were lost in improv- ing his understanding. He could never be brought to have any sense of religion, nor even to show the least signs of a reasoning faculty. They attempted to teach him dancing and music, but in vain : he never could make any thing of music; and as for dancing, although he beat time tolerably exact, yet he could never remember the figure, but while his dan- cing master stood by to direct his motions. Notwithstanding, a mind thus destitute of un- derstanding was not without its passions ; an- ger and jealousy harassed it at times; nor was he without desires of another nature. At the age of sixteen, Baby wns twenty-nine inches tall ; at this he rested ; but having thus arrived at his acme, the alterations of puber- ty, or rather, perhaps, of old age, came fast upon him. From being very beautiful, the poor little creature now became quite deform- ed; his strength quite forsook him; his back- bone began to bend ; his head hung forward ; his legs grew weak; one of his shoulders turn- ed awry; and his nose grew disproportionably large. With his strength, his natural spirits also forsook him ; and, by the time he was twenty, he was grown feeble, decrepit, and marked with the strongest impressions of old age. It had been before remarked by some, that he would die of old age before he arriv- ed at thirty; and, in fact, by the time he was twenty-two, he could scarcely walk a hun- dred paces, being worn out with the multipli- r city of his years, and bent under the burden of protracted life. In this year he died : a cold, attended with a slight fever, threw him into a kind of lethargy, which had a few mo- mentary intervals ; but he could scarcely 'be brought to speak. However, it is asserted, that in the five last years in his life he show- ed a clearer understanding than in his times of best health : but at length he died, after enduring great agonies, in the twenty-second year of his age. Opposite to this accidental diminution of the human race, is that of its extraordinary magnitude. Concerning the reality of a na- tion of giants, there have been many disputes among the learned. Some have affirmed the probability of such a race ; and others, as warmly have denied the possibility of their existence. But it is not from any speculative reasonings, upon a subject of this kind, that information is to be obtained ; it is not from the disputes of I he scholar, but the labours of the enterprising, that we are to be instructed in this inquiry. Indeed, nothing can be more absurd, than what some learned men have ad- vanced upon this subject. It is very unlike- ly, says Grew, that there should either be dwarfs or giants; or if such, they cannot be fitted for the usual enjoyment of life and rea- son. Had man been born a dwarf, he could not have been a reasonable creature : for to that end, he must have a jolt head, and then he would not have body and blood enough to supply his brain with spirits ; or if he had a small head, proportionable to his body, there would not be brain enough for conduct- ing life. But it is still worse with giants; and there could never have been a nation of such, for there would not be food enough found in any country to sustain them ; or, if there were beasts sufficient for this purpose, there would not be grass enough for their maintenance. But what is stiU more, add others, giants could ANIMALS. 191 never be able to support the weight of their own bodies ; since a man of ten feet high, must be eight times as heavy as one of the ordinary stature ; whereas he has but twice the size of muscles to support such a burden : and, con- sequently, would be overloaded with the weight of his own body. Such arc the theories upon this subject; and they require no other answer, but that experience proves them both to be false : dwarfs are found capable of life and reason ; and giants are seen to carry their own bodies. We have several accounts from mari- ners, that a nation of giants actually exists ; and mere speculation should never induce us to doubt their veracity. Ferdinand Magellan was the first who dis- covered this race of people along the coast towards the extremity of South America. Ma- gellan was a Portuguese, of noble extraction ; who having long behaved with great bravery, under Albuquerque, the conqueror of India, he was treated with neglect by the court, upon his return. Applying, therefore, to the king of Spain, he was intrusted with the command of five ships, to subdue the Molucca islands ; upon one of which he was slain. It was in his voyage thither, that he happened to winter in St. Julian's Bay, an American harbour, forty-nine degrees south of the line. In this desolate region, where nothing was seen but objects of terror, where neither trees nor ver- dure drest the face of the country, they remain- ed for some months without seeing any human creature. They had judged the country to be utterly uninhabitable ; when one day, they saw approaching, as if he had been dropt from the clouds, a man of enormous stature, dancing and singing, and putting dust upon his head, as they supposed, in token of peace. This overture for friendship was, by Magellan's command, quickly answered by the rest of his men ; and the giant approaching, testified every mark of astonishment and surprise. He was so tall, that the Spaniards only reached his waist ; his face was broad, his colour brown, and painted over with a variety of tints ; each cheek had the resemblance of a heart drawn upon it ; his hair was approaching to white- ness ; he was clothed in skins, and armed with a bow. Being treated with kindness, and dis- missed with some trifling presents, he soon re- turned with many more of the same stature ; two of whom the mariners decoyed on ship- board : nothing could be more gentle than they were in the beginning ; they considered the fetters that were preparing for them as orna- ments, and played with them like children with their toys ; but when they found for what pur- pose they were intended, they instantly exert- ed their amazing strength, and broke them in pieces with a very easy effort. This account, with a variety of other circumstances, has been confirmed by succeeding travellers : Herrara, Scbald, Wert, Oliver Van Noort, and James le Maire, all correspond in affirming the fact, although they differ in many particulars of their respective descriptions. The last voyager we have had, that has seen this enormous race, is Commodore Byron. I have talked with the person who first gave the relation of that voy- age,and who was the carpenter of the Commo- dore's ship ; he was a sensible, understanding man, and I believe extremely faithful. By him, therefore, I was assured, in the most solemn manner, of the truth of his relation ; and this account has since been confirmed by one or two publications ; in all which the particulars are pretty nearly the same. One of the circum- stances which most puzzled me to reconcile to probability, was that of the horses, on which they are described as riding down to the shore. We know the American horse to be of Euro- pean breed ; and, in some measure, to be de- generated from the original. I was at a loss, therefore, to account how a horse of not more than fourteen hands high, was capable of car- rying a man of nine feet ; or, in other words, an animal almost as large as itself. But the wonder will cease, when we consider, that so small a beast as an ass, will carry a man of ordinary size tolerably well; and the proportion between this and the former instance is nearly exact. We can no longer, therefore, refuse our assent to the existence of this gigantic race of mankind : in what manner they are propaga- ted, or under what regulation's they live, is a subject that remains for future investigation. It should appear, however, that thfy are a wandering nation, changing their abode with the courscTof the sun, and shifting their situa- tion, for the convenience of food, climate, or pasture." This race of giants are described as possessed a Later voyagers have not confirmed this account, in some particulars. 192 A HISTORY OF of great strength; and, no doubt, they must be very different from those accidental giants that are to be seen in different parts of Europe. Stature, with these, seems rather their infirmity than their pride ; and adds to their burden, without increasing their strength. Of those I have seen, the generality were ill formed and unhealthful ; weak in their persons, or incapable of exerting what strength they were jj possessed of. The same defects of understand- ing that attended those of suppressed stature, were found in those who were thus overgrown : they were heavy, phlegmatic, stupid, and in- clined to sadness. Their numbers, however, are but few ; and it is thus kindly ordered by Providence, that as the middle stature is the best fitted for happiness, so the middle ranks of mankind are produced in the greatest variety. However, mankind seems naturally to have a respect for men of extraordinary stature ; and it has been a supposition of long standing, that our ancestors were much taller, as well as much more beautiful, than we. This has been, in- deed, a theme of poetical declamation from the beginning ; and man was scarcely formed, when he began to deplore an imaginary decay. Nothing is more natural than this progress of the mind, in looking up to antiquity with reve- rential wonder. Having been accustomed to compare the wisdom of our fathers with our own, in early imbecility, the impression of their superiority remains when they no longer exist, and when we cease to be inferior. Thus the men of every age consider the past as wiser than the present ; and the reverence seems to accumulate as our imaginations ascend. For this reason, we allow remote antiquity many advantages, without disputing their title : the inhabitants of uncivilized countries represent them as taller and stronger ; and the people of a more polished nation, as more healthy and more wise. Nevertheless, these attributes seem to be only the prejudices of ingenuous minds; a kind of gratitude, which we hope in turn to receive from posterity. The ordinary stature of men, Mr. Derham observes, is, in all pro- bability, the same now as at the beginning. The oldest measure we have of the human figure, is in the monument of Cheops, in the first pyramid of Egypt. This must have sub- sisted many hundred years before the times of Homer, who is the first that deplores the decay. This monument, hoivcver, scarcely exceeds the measure of our ordinary coffins : the cavity is no more than six feet long, two feet wide, and deep in about the same proportion. Several mummies also, of a very early age, are found to be only of the ordinary stature ; and show that, for these three thousand years at least, men have not suffered the least diminution. We have many corroborating proofs of this, in the ancient pieces of armour which are dug up in different parts of Europe. The brass hel- met dug up at Medauro, fits one of our men, and yet is allowed to have been left there at the overthrow of Asdrubal. Some of our finest antique statues, which we learn from Pliny and others to be exactly as big as the life, still continue to this day, remaining monuments of the superior excellence of their workmen indeed, but not of the superiority of their stature. We may conclude, therefore, that men have been in all ages pretty much of the same size they are at present; and that the only difference must have been accidental, or perhaps na- tional. As to the superior beauty of our ancestors, it is not easy to make the comparison : beauty seems a very uncertain charm ; and frequently is less in the object, than in the eye of the be- holder. Were a modern lady's face formed exactly like the Venus of Medicis, or the Sleep- ing Vestal, she would scarcely be considered beautiful, except by the lovers of antiquity, whom of all her admirers perhaps she would be least desirous of pleasing. It is true, that we have some disorders among us that disfigure the features, and from which the ancients were exempt ; but it is equally true, that we want some which were common among them, and which were equally deforming. As for their intellectual powers, these also were probably the same as ours : we excel them in the sciences, which may be considered as a history of ac- cumulated experience ; and they excel us in the poetic arts, as they had the first rifling of all the striking images of Nature. ANIMALS 193 CHAPTER XXXV. OF MUMMIES, WAX-WORKS, &c. " MAN 8 is not content with the usual term of life, but he is willing to lengthen out his ex- istence by art ; and although he cannot pre- vent death, he tries to obviate his dissolution. It is natural to attempt to preserve even the most trifling relics of what has long given us pleasure ; nor does the mind separate from the body, without a wish, that even the wretch- ed heap of dust it leaves behind may yet be remembered. The embalming, practised in various nations, probably had its rise in this fond desire : an urn filled with ashes, among the Romans, served as a pledge of continu- ing affection; and even the grassy graves in our own church-yards, are raised above the surface, with the desire that the body below should not be wholly forgotten. The soul, ardent after eternity for itself, is willing to procure, even for the body, a prolonged du- ration." But of all nations, the Egyptians carried this art to the highest perfection : as it Avas a principle of their religion, to suppose the soul continued only coeval to the duration of the body, they tried every art to extend the life of the one by preventing the dissolution of the other. In this practice they were ex- ercised from the earliest ages ; and the mum- mies they have embalmed in this manner, con- tinue in great numbers to the present day. We are told, in Genesis, that Joseph seeing his father expire, gave orders to his physici- ans to embalm the body, which they execu- ted in the compass of forty days, the usual time of embalming. Herodotus also, the most ancient of the profane historians, gives us a copious detail of this art, as it was practised, in his time, among the Egyptians. There are certain men among them, says he, who prac- tise embalming as a trade ; which they per- form with all expedition possible. In the first place, they draw out the brain through* the * This chapter I have, in a great measure, translated from Mr. Daubenton. Whatever is atlded from others, is marked with inverted commas. nostrils, with irons adapted to this purpose; and in proportion as they evacuate it in this manner, they fill up the cavity with aro- matics : they next cut open the belly, near the sides, with a sharpened stone, and take out the entrails, which they cleanse, and wash in palm oil ; having performed this operation, they roll them in aromatic powder, fill them with myrrh, cassia, and other perfumes, ex- cept incense ; and replace them, sewing up the body again. After these precautions, they salt the body with nitre, and keep it in the salting-place for seventy days, it not being per- mitted to preserve it so any longer. When the seventy days are accomplished, and the body washed once more, they swathe it in bands made of linen, which have been dipt in a gum the Egyptians use instead of salt. When the friends have taken back the body, they make a hollow trough, something like the shape of a man, in which they place the body ; and this they enclose in a box, preserving the whole as a most precious relic, placed against the wall. Such are the ceremonies used with regard to the rich. As for those who are con- tented with a humbler preparation, they treat them as follows : they fill a syringe with an odoriferous liquor extracted from the cedar- tree, and, without making any incision, inject it up the body of the deceased, and then keep it in nitre, as long as in the former case. When the time is expired, they evacuate the body of the cedar liquor which had been in- jected ; and such is theefTect of this operation, that the liquor dissolves the intestines, and brings them away : the nitre also serves to eat away the flesh, and leaves only the skin and the bones remaining. This done, the body is returned to the friends, and the embalmer takes no farther trouble about it. The third method of embalming those of the meanest condition, is merely by purging and cleansing the intestines by frequent injections, and pre- serving the body for a similar term in nitre, at the end of which it is restored to the re- lations. 194 A HISTORY OF Diodprus Siculus also makes mention of the manner in which these embalmings are per- formed. According to him, there were seve- ral officers appointed for this purpose; the first of them, who was called the scribe, mark- ed those parts of the body, on the left side, which were to be opened ; the cutter made the incision; and one of those that were to salt it drew out all the bowels, except the heart and the kidneys ; another washed them in palm wine and odoriferous liquors; after- wards they anointed for above thirty days with cedar, gum, myrrh, cinnamon, and other perfumes. These aromatics preserved the body entire for a long time, and gave a very agreeable odour. It was not in the least dis- figured by this preparation; after which it was returned to the relations, who kept it in a coffin, placed upright against a wall. Most of the modern writers who have treat- ed on this subject, have merely repeated what has been said by Herodotus ; and if they add any thing of their own, it is but merely from conjecture. Dumont observes, that it is very probable, that aloes, bitumen, and cinnamon, make a principal part of the composition which is used on this occasion : he adds, that, after embalming, the body is put into a coffin, made of the sycamore-tree, which is almost incorruptible. Mr. Grew remarks, that in an Egyptian mummy, in the possession of the Royal Society, the preparation was so pene- trating as to enter into the very substance of the bones, and rendered them so black, that they seemed to have been burnt. From this he is induced to believe, that the Egyptians had a custom of embalming their dead, by boiling them in a kind of liquid preparation, until all the aqueous parts of the body were exhaled away ; and until the oily or gummy matter had penetrated throughout. He pro- poses, in consequence of this, a method of macerating, and afterwards of boiling, the body in oil of walnut. I am, for my own part, of opinion, that there were several ways of preserving dead bodies from putrefaction; and that this would be no difficult matter, since different nations have all succeeded in the attempt. We have an example of this kind among the Guanches, the ancient inhabitants of the island of Te- neriffi Those who survived the general de- struction of this people by the Spaniards, when they conquered this island, informed them, that the art of embalming was still pre- served there ; and that there was a tribe of priests among them possessed of the secret, which they kept concealed as a sacred mys- tery. As the greatest part of the nation was destroyed, the Spaniards could not arrive at a complete knowledge of this art; they only found out a few of the particulars. Having taken out the bowels, they washed the body several times in a lee, made of the dried bark of the pine-tree, warmed, during the summer, by the sun, or by a stove in the winter. They afterwards anointed it with butter, or the fat of bears, which they had previously boiled with odoriferous herbs, such as sage and la- vender. After this unction, they suffered the body to dry ; and then repeated the operati- on as often as it was necessary, until the whole substance was impregnated with the prepa- ration. When it was become very light, it was then a certain sign that it was fit and pro- perly prepared. They then rolled it up in the dried skins of goats ; which, when they had a mind to save expense, they suffered to remain with the hair still growing upon them. Purchas assures us, that he has seen mummies of this kind in London; and mentions the name of a gentleman who had seen several of them in the island of TeneriffJ which were supposed to have been two thousand years old ; but without any certain proofs of such great antiquity. This people, who probably came first from the coasts of Africa, might have learned this art from the Egyptians, as there was a traffic carried on from thence into the most internal parts of Africa. Father Acosta and Garcilasso de la Vega make no doubt but that the Peruvians under- stood the art of preserving their dead for a very long space of time. They assert their having seen ihe bodies of several incas, that were perfectly preserved. They still preserv- ed their hair and their eye-brows; but they had eyes made of gold, put in the places of those taken out. They were clothed in their usualliabits, and seated in the manner of the Indians, their arms placed on their breasts. Garcilasso touched one of their fingers, and found it apparently as hard as wood ; and the whole body was not heavy enough to over ANIMALS. 195 burden a weak mnn, who should attempt to carry it away. Acosta presumes that these bodies were embalmed with a bitumen, of which the Indians knew the properties. Gar- cil is-;o, however, is of a different opinion, as he s.iw nothing bituminous about them ; but he confesses that he di-l not examine them very particularly; an I he regrets his not having in- quired into the methods used for that purpose. He adds, tiiat being a Peruvian, his country- men would not have scrupled to inform him of the secret, if they really had it still among them. Garcilasso, thus being ignorant of the secret, makes use of some inductions to throw light upon the subject; he asserts, that the air is so dry and so cold at Cusco, that flesh dries there like wood, without corrupting ; and he is of opinion, that they dried the body in snow be- fore they applied the bitumen : he adds, that in the times of the incas, they usually dried the flesh which was designed for the use of the army ; and that, when it had lost its humidity, it .night be kept without salt, or any other preparation. It is said, that at Spitzbergen, which lies within the arctic circle, and consequently in the coldest climate, bodies never corrupt, nor suffer any apparent alteration, even though buried for thirty years. Nothing corrupts or putrefies in that climate ; the wood which has been employed in building those houses where the train-oil is separated, appears as fresh as the day it was first cut. If excessive cold, therefore, be thus capable of preserving bodies from corruption, it is not less certain that a great degree of dryness, pro- duced by heat, produces the same effect. It is well known that the men and animals that are buried in the sands of Arabia quickly dry up, and continue in preservation for several 'ages, as if they had been actually embalmed. It has often happened, that whole caravans have perished in crossing those deserts, either by the burning winds that infest them, or by the sands which are raised by the tempest, and over- whelm every creature in certain ruin. The bodies of those persons are preserved entire ; and they are often found in this condition by soiiie accidental passenger. Many authors, both ancient and modern, make mention of such mummies as these ; and Shaw says, that he has been assured that numbers of men, as well as other animals, have been tfius preserv- ed, for times immemorial, in the burning sands of Saibah, which is a place, he supposes, situate between Kasein and Kgypt. The corruption of dead bodies being entire- ly caused by the fermentation of the humours, whatever is capable of hindering or retarding this fermentation, will contribute to their pre- servation. Both heat and cold, though so contrary in themselves, produce similar effects in this particular, by drying up the humours. The cold in condensing and thickening them, and the heat in evaporating them before they have time to act upon the solids. But it is necessary that these extremes should be con- stant ; for if they succeed each other so as that cold shall follow heat, or dryness humidity, it must then necessarily happen that corrnp ion must ensue. However, in temperate climates, there are natural causes capable of preserving dead bodies; among which we may reckon the quality of the earth in which they are buried. If the earth be drying and astringent, it nil! imbibe the humidity of the body ; and it n>av probably be for this reason that the bodies buried in the monastery of the Cordeliers, at Thoulouse, do not putrefy, but dry in such a manner that they may be lifted up by one arm. The gums, resins, and bitumens, with which dead bodies are embalmed, keep off the im- pressions which they would else receive from thealteration of the temperature of the air; and still more, if a body thus prepared be placed in a dry or burning sand, the most powerful means will be united for its preservation. We are not to be surprised, therefore, at w hat we are told by Chardin, of the country of Chorosan, in Persia. The bodies which have been pre- viously embalmed, and buried in the sands of that country, as he assures us, are found to petrefy, or, in other words, to become ex- tremely hard, and are preserved for sevi ral ages. It is asserted, that some of them have continued for a thousand years. The Egyptians, as has been mentioned above, swathed the body with linen bands, and en- closed it in a coffin : however, it is probable that, with all these precautions, they would not have continued till now, if the tombs, or pits, in which they were placed, had not been dug in a dry chalky soil, which was not susceptible of humidity; and which was besides covered over with a dry sand of several feet thickness. 2 M 196 A HISTORY OF The sepulchres of the ancient Egyptians subsist to this day. Most travellers who have been in Egypt have described those of ancient mummiesj and have seen the mummies interred there. These eatacombsare within two leagues of the ruins of the city, nine leagues from Grand Cairo, and about two miles from the village of Zaccara. They extend from thence to the Pyramids of Pharaoh, which are about eight miles distant. These sepulchres lie in a field, covered with a fine running sand, of a yellowish colour. The country is dry and hilly ; the entrance of the tombs is choked up with sand ; there are many open, but several more that are still concealed. The inhabitants of the neighbouring village have no other com- merce, or "method of subsisting, but by seeking out mummies, and selling them to such stran- gers as happen to be at Grand Cairo. This commerce, some years ago, was not only a very common, but a very gainful one. A com- plete mummy was often sold for twenty pounds: but it must not be supposed that it was bought at such a high price from a mere passion for antiquity ; there were much more powerful motives for this traffic. Mummy, at that time, made a considerable article in medicine ; and a thousand imaginary virtues were ascribed to it, for the cure of most disorders, particularly of the paralytic kind. There was no shop, therefore, without mummy in it ; and no phy- sician thought he had properly treated his patient without adding this to his prescription. Induced by the general repute, in which this supposed drug was at that time, several Jews, both of Italy and France, found out the art of imitating mummy so exactly, that they, for a long time, deceived all Europe. This they did by drying dead bodies in ovens, after having prepared them with myrrh, aloes, and bitumen. Still, however, the request for mummies con- tinued, and a variety of cures were daily ascribed to them. At length, Paraeus wrote a treatise on their total inefficacy in physic ; and showed their abuse in loading the stomach, to (he exclusion of more efficacious medicines. From that time, therefore, their reputation be- gan to decline ; the Jews discontinued their counterfeits, and the trade returned entire to the Egyptians, when it was no longer of value. The industry of seeking after mummies is now totally relaxed, their price merely arbitrary, and just what the curious are willing to give. In seeking for mummies, they first clear away the sand, which they may do for weeks to- gether, without finding what is wanted. Upon coming to a little square opening of about eighteen feet in depth, they descend into it, by holes for the feet, placed at proper intervals, and there they are sure of finding what they seek for. These caves, or wells, as they call them, are hollowed out of a white free-stone, which is found in all this country, a few feet below the covering of sand. When one gets to the bottom of these, which are sometimes forty feet below the surface, there are several square openings on each side, into passages of ten or fifteen feet wide, and these lead to cham- bers of fifteen or twenty feet square. These arc all hewn out of the rock ; and in each of the catacombs are to be found several of these apartments, communicating with each other. They extend a great way under ground, so as to be under the city of Memphis, and in a manner to undermine its environs. In some of the chambers, the walls are adorned with figures and hieroglyphics ; in others, the mummies are found in tombs round the apartment hollowed out in the rock. These tombs are upright, and cut into the shape of a man, with his arms stretched out. There are others found, and these in the greatest number, in wooden-coffins, or in cloths covered with bitumen. These coffins, or wrappers, are covered all over with a variety of ornaments. There are some of them painted, and adorned with figures, such as that of Death, and the leaden seals, on which several characters are engraven. Some of these coffins are carved into the human shape ; but the head alone is distinguishable : the rest of the body is all of a piece, and terminated by a pedestal, while there are some with their arms hanging down ; and it is by these marks that the bodies of persons of rank are distinguished from those of tlie meaner order. These are generally found ly- ing on the floor, without any profusion of orna- ments ; and in some chambers the mummies are found indiscriminately piled upon each other, and buried in the sand. Many mummies are found lying on their backs ; their heads turned to the north, and their hands placed on the belly. The bands of linen, with which these were swathed, are found to be more than a thousand yards long ; and, of consequence, the number of circum- ANIMALS. 197 volutions they make about the body must have been amazing. Those were performed by beginning at the head, and ending at the feet; but they contrived it so as to avoid co- vering the face. However, when the face is entirely uncovered, it moulders into dust im- mediately upon the admission of the air. When, therefore, it is preserved entire,a slight covering of cloth is so disposed over it, that the shape of the eyes, the nose, and the mouth, are seen under it. Some mummies have been found with a long beard, and hair that reach- ed down to the mid-leg, nails of a surprising length, and some gilt, or at least painted of a gold colour. Some are found with bands upon the breast, covered with hieroglyphics, in gold, silver, or in green; and some with tutelary idols, and other figures of jasper, within their body. A piece of gold also has often been found under their tongues, of about two pis- toles value ; and, for this reason, the Arabians spoil all the mummies they meet with, in order to get at the gold. But although art, or accident, has thus been found to preserve dead bodies entire, it must by uo means be supposed that it is capable tof preserving the exact form and lineaments of the deceased person. Those bodies which are found dried away in the deserts, or in some particular church-yards, are totally de- formed, and scarcely any lineaments remain of their external structure. Nor are the mum- mies preserved by embalming, in a better con- dition. The flesh is dried away, hardened, and hidden under a variety of bandages; the bowels, as we have seen, are totally removed ; and from hence, in the most perfect of them, we see only a shapeless mass of skin discolour- ed ; and even the features scarcely distin- guishable. The art is, therefore, an effort ra- ther of preserving the substance than the like- ness of the deceased ; and has, consequently, not been brought to its highest pitch of per- fection. It appears from a mummy, not long since dug up in France, that the art of embalm- ing was more completely understood in the western world than even in Egypt. This mum- my, which was dug up at Auvergne, was an amazing instance of their skill, and is one of the most curious relics in the art of preserva- tion. As some peasants, in that part of the world, were digging in a field, near Rion. with- in about twenty-six paces of the highway, be- tween that and the river Artiers, they disco- vered a tomb, about afoot and a half beneath the surface. It was composed only of two stones ; one of which formed the body of the sepulchre, and the other the cover. This tomb was of free-stone, seven feet and a halt long, three feet and a half broad, and aboul three feet high. It was of rude workmanship ; the cover had been polished, but was without figure or inscription : within this tomb was placed a leaden-coffin, four feet seven inches long, fourteen inches broad, and fifteen high. It was not made coffin-fashion, but oblong, like a box, equally broad at both ends, and covered with a lid that fitted on like a snuff- box, without a hinge. This cover had two holes in it, each of about two inches long, and very narrow, filled with a substance resem- bling butter; but for what purpose intended remains unknown. Within this coffin was a mummy, in the highest and most perfect pre- servation. The internal sides of the coffin were filled with an aromatic substance, min- gled with clay. Round the mummy was wrap- ped a coarse cloth, in form of a napkin; un- der this were two shirts, or shrouds, of the most exquisite texture ; beneath these a ban- dage, which covered all parts of the body, like an infant in swaddling-clothes; still un- der this general bandage there was another, which went particularly round the extremities, the hands, and the legs. The head was co- vered with two caps ; the feet and hands were without any particular bandages; and the whole body was covered with an aromatic substance an inch thick. When these were removed, arid thebody exposed naked to view, nothing could be more astonishing than the preservation of the whole, and the exact re- semblance it bore to a body that had been dead a day or two before. It appeared well proportioned, except that the head was rather large, and the feet small. The skin had all the pliancy and colour of a body lately dead : the visage, however, was of a brownish hue. The belly yielded to the touch ; all the joints were flexible, except those of the legs and f \ e success only i to patience, perseverance, and industry. The feet of some, that live upon lish alone, are made for swimming. Tlu- ! s of these ani- mals are joined together \\iih membranes, being web-footed like a goose or a duck, by which they swim with great rar.idjty. Those animals that lead a life of hostility, and live ANIMALS. 207 upon others, have their feet armed with sharp claws, which some can sheath and unsheath at will. Those, on the contrary, who lead peaceful lives, have generally hoofs, which serve some as weapons of defence; and which, in all, are better fitted for traversing extensive tracts of rugged country than the claw-foot of their pursuers. The stomach is generally proportioned to the quality -of the animal's food, or the ease with which it is obtained. In those that live upon flesh, and such nourishing substances, it is small and glandular, affording such juices as are best adapted to digest its contents; their intestines also are short, and without fatness. On the contrary, such animals as feed entirely upon vegetables, have the sto- mach very large ; and those who chew the cud have no less than four stomachs, all which serve as so many laboratories, to prepare and turn their coarse food into proper nourish- ment. In Africa, where the plants afford greater nourishment than in our temperate climates, several animals, that with us have four stomachs, have there but two." How- ever, in all animals the size of the intestines is proportioned to the nature of the food : where that is furnished in large quantities, the stomach dilates to answer the increase. In domestic animals, that are plentifully sup- plied, it is large ; in the wild animals, that live precariously, it is much more contracted, and the intestines are much shorter. In this manner, all animals are fitted by na- ture to fill up some peculiar station. The Mtest animals are made for an inoffensive life, to range the plains and the forest without injuring others; to live upon the productions of the earth, the grass of the field, or the ten- df-i branches of trees. These, secure in their own strength, neither fly from any other quad- rupeds, nor yet attack them : Nature, to the greatest strength, has added the most gentle and harmless dispositions : without this, those enormous creatures would be more than a match for all the rest of the creation; for what devastation might not ensue, were the elephant, or the rhinoceros, or the buffalo, as fierce -and as mischievous as the tiger or the rat ? In order to oppose these larger animals, Bufion. and in some measure to prevent their exuber- ance, there is a species of the carnivorous kind, of inferior strength indeed, but of greater activity and cunning. The lion and the tiger generally watch for the larger kinds of prey, attack them at some disadvantage, and com- monly jump upon them by surprise. None of the carnivorous kinds, except the dog alone, will make a voluntary attack, but with the odds on their side. They are all cowards by na- ture, and usually catch their prey by a bound from some lurking-place, seldom attempting to invade them openly; for the larger beasts are too powerful for them, and the smallei too swift. A lion does not willingly attack a horse ; and then only when compelled by the keen- est hunger. The combats between a lion and a horse are frequent enough in Italy ; where they are both enclosed in a kind of amphitheatre, fitted for that purpose. The lion always approaches wheeling about, while the horse presents his hinder parts to the ene- my. The lion in this manner goes round and round, still narrowing his circle, till he comes to the proper distance to make his spring; just at the time the lion springs, the horse lashes with both legs from behind, and, in ge- neral, the odds are in his favour ; it more often happening that the lion is stunned, and struck motionless by the blow, than that he effects his jump between the horse's shoulders. If the lion is stunned, and left sprawling, the horse escapes, without attempting to improve his victory ; but if the lion succeeds, he sticks to his prey, and tears the horse in pieces in a very short time. But it is not among the larger animals of the forest alone, that these hostilities are car- ried on ; there is a minuter, and a still more treacherous contest, between the lower ranks of quadrupeds. The panther hunts for the sheep and the goat ; the catamountain for the hare or the rabbit; and the wild cat for the squirrel or the mouse. In proportion as each carnivorous animal wants strength, it uses all the assistance of patience, assiduity, and cun- ning. However, the arts of these to pursue, are not so great as the tricks of their prey to escape; so that the power of destruction in one class, is inferior to the power of safety in the other. Were this otherwise, the forest 208 A HISTORY OF would soon be dispeopled of the feebler races of animals; and beasts of prey themselves would want, at one time, that subsistence which they lavishly destroyed at another. Few wild animals seek their prey in the day-time ; they are then generally deterred by their fears of man in the inhabited coun- tries, and by the excessive heat of the sun in those extensive forests that lie towards the south, and in which they reign the un- disputed tyrants. As soon as the morning, therefore, appears, the carnivorous animals retire to their dens ; and the elephant, the horse, the deer, and all the hare kinds, those inoffensive tenants of the plain, make their appearance. But again, at night-fall, the state of hostility begins ; the whole forest then echoes to a variety of different bowlings. Nothing can be more terrible than an African landscape at the close of evening; the deep- toned roarings of the lion ; the shriller yell- ings of the tiger; the jackal, pursuing by the scent, and barking like a dog; the hypena, with a note peculiarly solitary and dreadful ; but, above all, the hissing of the various kinds of serpents, that then begin their call, and, as I am assured, make a much louder sympho- ny than the birds in our groves in a morning. Beasts of prey seldom devour each other ; nor can any thing but the greatest degree of hunger induce them to it. What they chiefly seek after, is the deer, or the goat ; those harmless creatures, that seem made to em- bellish nature. These are either pursued or surprised, and afford the most agreeable re- past to their destroyers. The most usual method with even the fiercest animals, is to hide and crouch near some path frequented by their prey ; or some water where cattle come to drink; and seize them at once with a bound. The lion and the tiger leap twenty feet at a spring ; and this, rather than their swiftness or strength, is what they have most to depend upon for a supply. There is scarcely one of the deer or hare kind, that is not very easily capable of escaping them by its swiftness ; so that whenever any of these fall a prey, it must be owing to their own inatten- tion. But there is another class of the carnivo- rous kind, that hunt by the scent, and which it is much more difficult to escape. It is re- markable, that all animals of this kind pur- sue in a pack; and encourage each other by their mutual cries. The jackal, the syagush, the wolf, and the dog, are of this kind ; they pursue with patience rather than swiftness ; their prey flies first, and leaves them for miles behind ; but they keep on with a constant steady pace, and excite each other by a gene- ral spirit of industry and emulation, till at last they share the common plunder. But it too often happens, that the larger beasts of prey, when they hear a cry of this kind begun, pur- sue the pack, and when they have hunted down the animal, come in and monopolize the spoil. This has given rise to the report of the jackal's being the lion's provider ; when the reality is, that the jackal hunts for itself, and the lion is an unwelcome intruder upon the fruit of his toil. Nevertheless, with all the powers which carnivorous animals are possessed of, they generally lead a life of famine and fatigue. Their prey has such a variety of methods for escaping, that they sometimes continue with- out food for a fortnight together : but nature has endowed them with a degree of patience equal to the severity of their state; so that as their subsistence is precarious, their ap- petites are complying. They usually seize their prey with a roar, either of seeming de- light, or perhaps to terrify it from resistance. They frequently devour it, bones and all, in the most ravenous manner ; and then retire to their dens, continuing inactive, till the calls of hunger again excite their courage and in- dustry. But as all their methods of pursuit are counteracted by the arts of evasion, they often continue to range without success, sup- porting a state of famine for several days, nay, sometimes, weeks together. Of their prey, some find protection in holes, in which na- ture has directed them to bury themselves ; some find safety by swiftness ; and such as are possessed of neither of these advantages, generally herd together, and endeavour to repel invasion by united force. The very sheep, which to us seem so defenceless, are by no means so in a state of nature ; they are furnished with arms of defence, and a very great degree of swiftness; but they are still further assisted by their spirit of mutual de- fence : the females fall into the centre ; and ANIMALS. 209 the males, forming a ring round them, oppose their horns to the assailants. v Some animals, that feed upon fruits which are to be found only at one time of the year, fill their holes with several sorts of plants, which enable them to lie concealed during the hard frosts of the winter, contented with their prison, since it affords them plenty and pro- tection. These holes are dug with so much art, that there seems the design of an architect in the formation. There are usually two aper- tures, by one of which the little inhabitant can always escape, when the enemy is in possession of the other. Many creatures are equally careful of avoiding their enemies, by placing a centinel to w ; arn them of the approach of j danger. These generally perform this duty by turns ; and they know how to punish such as have neglected their post, or have been un- mindful of the common safety. Such are a part of the efforts that the weaker races of quadrupeds exert to avoid their invaders; and, in general, they are attended with success. The arts of instinct are most commonly found an overmatch for the invasions of instinct. Man is the only creature against whom all their little tricks cannot prevail. Wherever he has spread his dominion, scarcely any flight can save, or any retreat harbour ; wherever he comes, terror seems to follow, and all society ceases among the inferior tenants of the plain ; their union against him can yield them no protection, and their cunning is but weakness. In their fellow-brutes, they have an enemy whom they can oppose with an equality of advantage; they can oppose fraud or swift- ness to force, or numbers to invasion ; but what can be done against such an enemy as man, who finds them out though unseen ; and though remote, destroys them ? Wherever he comes, all the contest among the meaner ranks seem to be at an end, or is carried on only by surprise. Such as he has thought proper to protect, have calmly submitted to his protec- tion ; such as he has found it convenient to destroy, carry on an unequal war, and their numbers are every day decreasing. The wild animal is subject to few altera- tions ; and, in a state of savage nature, con- tinues for ages the same, in size, shape, and colour. But it is otherwise when subdued, and taken under the protection of man ; its external form, and even its internal structure, are altered by human assiduity : and this is one of the first and greatest causes of the va- riety that we see among the several quadru- peds of the same species. Man appears to have changed the very nature of domestic ani- mals, by cultivation and care. A domestic animal is a slave that seems to have few other desires but such as man is willing to allow it. Humble, patient, resigned, and attentive, it fills up the duties of its station ; ready for la- bour, and content with subsistence. Almost all domestic animals seem to bear the marks of servitude strong upon them. All the varieties in their colour, all the fineness and length of their hair, together with the de- pending length of their ears, seem to have arisen from a long continuance of domestic slavery. What an immense variety is there to be found in the ordinary race of dogs and horses! the principal differences of which have been effected by the industry of man, so adapt- ing the food, the treatment, the labour, and the climate, that Nature seems almost to have forgotten her original design ; and the tame animal no longer bears any resemblance to its ancestors in the woods around him. In this manner, nature is under a kind of constraint, in those animals we have taught to live in a state of servitude near us. The savage animals preserve the marks of their first formation; their colours are generally the same ; a rough dusky brown, or a tawny, seem almost their only varieties. But it is other- wise in the tame ; their colours arc various, and their forms different from each other. The nature of the climate indeed operates upon all; but more particularly on these. That nourish- ment which is prepared by the hand of man, not adapted to their appetites, but to suit his own convenience ; that climate, the rigours of which he can soften; and that employment to which they are sometimes assigned ; produce a number of distinctions that are not to be found among the savage animals. These, at first, were accidental, but in time became here- ditary ; and a new race of artificial monsters are propagated, rather to answer the purposes of human pleasure than their own convenience. In short, their very appetites may be changed; and those that feed only upon grass may be rendered carnivorous. I have seen a sheep that would eat flesh, and a horse that was fond of ovsters. 210 A HISTORY OF But not their appetites, or their figure alone, but their very dispositions, and their natural sagacity, are altered by the vicinity of man. In those countries where men have seldom in- truded, some animals have been found, estab- lished in a kind of civil state of society. Re- mote from the tyranny of man, they seem to have a spirit of mutual benevolence, and mu- tual friendship. The beavers, in those distant solitudes, are known to build like architects, and rule like citizens. The habitations that these have been seen to erect, exceed the houses of the human inhabitants of the same country, both in neatness and convenience. But as soon as man intrudes upon their society, they seem impressed with the terrors of their inferior situation, their spirit of society ceases, the bond is dissolved, and every animal looks for safety in solitude, and there tries all its little industry to shift only for itself. Next to human influence, the climate seems to have the strongest effects both upon the nature and the form of quadrupeds. As in man we have seen some alterations produced by the variety of his situation ; so in the lower ranks, that are more subject to variation, the influence of climate is more readily perceived. As these are more nearly attached to the earth, and in a manner connected to the soil ; as they have none of the arts of shielding off the inclemency of the weather, or softening the rigours of the sun, they are consequently more changed by its variations. In general it may be remarked, that the colder the country, the larger and the warmer is the fur of each ani- mal ; it being wisely provided by Nature, that the inhabitant should be adapted to the rigours of its situation. Thus the fox and wolf, which in temperate climates have but short hair, have a fine long fur in the frozen regions near the pole. On the contrary, those dogs which with us have long hair, when car- ried to Guinea or Angola, in a short time cast their thick covering, and assume a lighter dress, and one more adapted to the warmth of the country. The beaver, and the ermine, which are found in the greatest plenty in the cold re- gions, are remarkable for the warmth and delicacy of their furs ; while the elephant, and the rhinoceros, that are natives of the line, have scarcely any hair. Not but that human in- dustry can, in some measure, co-operate with, or repress, the effects of climate in this par- ticular. It is well known what alterations are produced by prop< r eai , in the sheep's fleece, in different parts of our own country ; and the same industry is pursued with alike success in Syria, where many of their animals are cloth- ed with a long and beautiful hair, which they take care to improve, as they work it into that stuff call'-d camblet, so well known in different parts of Europe. The disposition of the animal seems also not less marked by the climate than the figure. The same causes that seem to have rendered the human inhabitants of the rigorous climates savage and ignorant, have also operated upon their animals. Both at the line and the pole, the wild quadrupeds are fierce and untame- able. In these latitudes, their savage disposi- tions having not been quelled by any efforts from man, and being still farther stimulated by the severity of the weather, they continue fierce and uutrnetable. Most of the attempts which have hitherto been made to tame the wild beasts brought home from the pole or the equator, have proved ineffectual. They are gentle and harmless enough while young; hut as they grow up, they acquire their natural ferocity, and snap at the hand that feeds them. It may indeed, in general, be asserted, that in all countries where the men are most barba- rous, the beasts are most fierce and cruel : and this is but a natural consequence of the strug- gle between man and the more savage animals of the forest; for in proportion as he is weak and timid, they must be bold and intrusive; in proportion as his dominion is but feebly supported, their rapacity must be more ob- noxious. In the extensive countries, therefore, lying round the pole, or beneath the line, the quadrupeds are fierce and formidable. Africa has ever been remarked for the brutality of its men, and the fierceness of its animals : its lions and its leopards are not less terrible than its crocodiles and its serpents ; their dispositions seem entirely marked with the rigours of the climate, and being hred in an extreme of heat, they show a peculiar f rocity, that neither the force of man can conquer, nor his arts allay. However, it is happy for the wretched inhabi- tants of those climates, that its most formidable animals are all solitary ones ; that they have not learnt the art of uniting, to oppress man- kind ; but each depending on its own strength, invades without any assistant. ANIMALS. 211 The food also is another cause of the va- riety which \ve rind among quadrupeds of the same kind. Thus the beasts which feed in the valley are generally larger than those which glean a scanty subsistence on the moun- tain. Such as live in the warm climates, where the plants are much larger and moresucculcnt than with us, are equally remarkable for their bulk. The ox fed in the plains of Indostan, is much larger than that which is more hardi- ly maintained on the side of the Alps. The deserts of Africa, where the plants areextreme- ly nourishing, produce the largest and fiercest animals ; and, perhaps for a contrary reason, America is found not to produce such large animals as are seen in the ancient continent. But, whatever be the reason, the fact is certain, that while America exceeds us in the sixe of its reptiles of all kinds, it is far inferior in its auadruped productions. Thus, for instance, le largest animal of that country is the tapir, which can by no means be compared to the elephant of Africa. Its beasts of prey, also, are divested of that strength and courage which is so dangerous in this part of the world. The American lion, tiger, and leopard, if such diminutive creatures deserve these names, are neither so fierce nor so valiant as those of Africa and Asia. The tiger of Bengal has been seen to measure twelve feet in length, without including the tail: whereas the American ti- ger seldom exceeds three. This difference obtains still more in the other animals of that country, so that some have been of opinion" that all quadrupeds in Southern America are of a different species from those most resem- bling them in the old world ; and that there are none which are common to both, but such as have entered America by the north ; and which, being able to bear the rigours of the frozen pole, have travelled from the ancient continent, by that passage, into the new. Thus the bear, the wolf, the elk, the stag, the fox, and the beaver, are known to the in- habitants as well of North America as of Russia ; while most of the various kinds to the southward, in both continents, bear no re- semblance to each other. Upon the whole, such as peculiarly belong to the new conti- nent are w ithout any marks of the quadruped a Buffon. NO. 19 & 20. perfection. They are almost wholly destitute of the power of defence ; they have neither formidable teeth, horns, or tail; their figure is awkward, and their limbs ill proportioned. Some among them, such as the ant-bear and the sloth, appear so miserably formed, as scarcely to have the power of moving and eating. They, seemingly, drag out a misera- ble and languid existence in the most desert, solitude; and would quickly have been de- stroyed in a country where there were inha- bitants, or powerful beasts to oppose them. But if the quadrupeds of the new continent be less, they arc found in much greater abun- dance; for it is a rule that obtains through nature, that the smallest animals multiply the fastest. The goat, imported from Europe to South America, soon begins to degenerate ; but as it grows less it becomes more prolific ; and, instead of one kid at a time, or two at the most, it generally produces live, and some- times more. What there is in the food, or the climate, that produces this change, we have not been able to learn; we might be apt to ascribe it to the heat, but that on the African coast, where it is still hotter, this rule does not obtain ; for the goat, instead of de- generating there, seems rather to improve. However, the rule is general among all quadrupeds, that those which are large and formidable produce but few at a time ; while such as are mean and contemptible are ex- tremely prolific. The lion, or tiger, have sel- dom above two cubs at a litter; while the cat, that is of a similar nature, is usually seen to have five or six. In this manner, the lower tribes become extremely numerous : and, but for this surprising fecundity, from their natu- ral weakness they would quickly be extir- pated. The breed of mice, for instance, would have long since been blotted from the earth, were the mouse as slow in production as the elephant. But it has been wisely provided, that such animals as can make but little re- sistance, should at least have a means ef re- pairing the destruction, which they must of- ten suffer, by their quick reproduction; that they should increase even among enemies, and multiply under tbe hand of the destroyer. On the other hand, if has as wisely been or- dered by Providence, that the larger kinds should produce but slowly; otherwise, as they 2O 212 A HISTORY OF require proportional supplies from nature, they would quickly consume their own store; and, of consequence, many of them would soon perish through want; so that life would thus be given without the necessary means of subsistence. In a word, Providence has most wisely balanced the strength of the great against the weakness of the little. Since it was necessary that some should be great and others mean, since it was expedient that some should live upon others, it has assisted the weakness of one by granting it fruit fulness; and diminished the number of the other by infecundity. In consequence of this provision, the larger creatures, which bring forth few at a time, seldom begin to generate till they have near- ly acquired their full growth. On the contra- ry, those which bring many, reproduce before they have arrived at their natural size. Thus the horse and the bull are nearly at their best before they begin to breed ; the hog and the rabbit scarcely leave the teat before they be- come parents in turn. Almost all animals likewise continue the time of their pregnan- cy in proportion to their size. The mare con- tinues eleven months with foal, the cow nine, the wolf five, and the bitch nine weeks. In all, the intermediate litters are the most fruit- ful ; the first and the last generally producing the fewest in number, and the worst of the kind. Whatever be the natural disposition of ani- mals at other times, they all acquire new cou- rage when they consider themselves as defend- ing their young. No terrors can then drive them from the post of duty ; the mildest begin to exert their little force, and resist the most formidable enemy. Where resistance is hope- less, they then incur every danger, in order to rescue their young by flight, and retard their own expedition by providing for their little ones. When the female oppossum, an ani- mal of America, is pursued,she instantly takes her young into a false belly, with which nature has supplied her, and carries them off, or dies in the endeavour. I have been lately as- sured of a she-fox, which, when hunted, took her cub in her mouth, and run for several miles without quitting it, until at last she was forced to leave it behind, upon the approach of a mastiff, as she ran through a farmer's yard. But, if at this period the mildest animals ac- quire new fierceness, how formidable must those be that subsist by rapine! At such times, no obstacles can stop their ravage, nor no threats can terrify ; the lioness then seems more hardy than even the lion himself. She attacks men and beasts indiscriminately, and carries all she can overcome reeking to her cubs, whom she thus early accustoms to slaugh- ter. Milk, in the carnivorous animals, is much more sparing than in others* and it may be for this reason that all such carry home their prey alive, that, in feeding their young, its blood may supply the deficiencies of nature, and serve instead of that milk with which they are so sparingly supplied. Nature, that has thus given them courage to defend their young, has given them instinct to choose the proper times of copulation, so as to bring forth when the provision suited to each kind is to be found in the greatest plen- ty. The wolf, for instance, couples in Novem- ber, so that the time of pregnancy continuing five months, it may have its young in April. The mare, who goes eleven months, admits the horse in summer, in order to foal about the beginning of May. On the contrary, those animals which lay up provisions for the win- ter, such as the beaver and the marmotte, cou- ple in the latter end of autumn, so as to have their young about January, against which sea- son they have provided a very comfortable store. These seasons for coupling, however, among some of the domestic kinds, are gene- rally in consequence of the quantity of pro- visions with which they are at any time sup- plied. Thus we may, by feeding any of these animals, and keeping off the rigour of the cli- mate, make them breed whenever we please. In this manner those contrive who produce lambs all the year round. The choice of situation in bringing forth is also very remarkable. In most of the rapa- cious kinds, the female takes the utmost pre- cautions to hide the place of her retreat from the male ; who otherwise, when pressed by hunger, would be apt to devour her cubs. She seldom, therefore, strays far from the den, and never approaches it while he is in view, nor visits him again till her young are capa- ble of providing for themselves. Such ani- mals as are of tender constitutions take the ANIMALS. 213 utmost care to provide a place of warmth, as well as safety, for their young ; the rapacious kinds bring forth in the thickest woods ; those that chew the cud, with the various tribes of the vermin kind, choose some hiding place in the neighbourhood of man. Some dig holes in the ground ; some choose the hollow of a tree ; and all the amphibious kinds bring up their young near the water, and accustom them betimes to their proper element. Thus Nature seems kindly careful for the protection of the meanest of her creatures : but there is one class of quadrupeds that seems entirely left to chance, that no parent stands forth to protect, nor no instructor leads, to teach the arts of subsistence. These are the quadrupeds that are brought forth from the egg, such as the lizard, the tortoise, and the crocodile. The fecundity of all other animals compared with these is sterility itself. These bring forth above two hundred at a time ; but, as the offspring is more numerous, the paren- tal care is less exerted. Thus the numerous brood of eggs are, without farther solicitude, buried in the warm sands of the shore, and the heat of the sun alone is left to bring them to perfection. To this perfection they arrive almost as soon as disengaged from the shell. Most of them, without any other guide than instinct, immediately make to the water. In their passage thither, they have numberless enemies to fear. The birds of prey that haunt the shore, the beasts that accidentally come there, and even the animals that give them birth, are known, with a strange rapacity, to thin their numbers as well as the rest. But it is kindly ordered by Providence, that these animals, which are mostly noxious, should thus have many destroyers : were it not for this, by their extreme fecundity, they would soon over-run the earth, and cumber all our plains with deformity. [" Thus throughout the whole economy of nature we may trace displays of infinite wis- dom,even in regulating theimpulses of instinc- tive power, and in governing its annual or va- ried tides. A mere system of organized mat- ter, without any independent and intelligent cause, could never have communicated to it- self that prescience which the numerous tribes of animals exhibit; and to ascribe the visible phenomena to chance, is to invest a mere ab- stract idea with attributes, which, even human knowledge, refined by all the light which phi- losophy imparts, is scarcely able to compre- hend. And even if we allow chance to have been the primitive cause of existence, and of the varied phenomena connected with it, we must ascribe to it that eternity of being which Atheism denies to the intelligent Creator; unless we conceive that chance, by chance, has begotten chance throughout an infinite series in past duration. The absurdity of such a supposition it would be folly to pursue. "That many things appear inexplicable in the economy and overruling Providence of God, will be most readily allowed. In every department, shadows, and obscurities, veil from human penetration a considerable por- tion of his ways. In the vast chain of being, a few links only are open to human inspec- tion ; and even these the dimness of our bodi- ly organs and mental powers will not permit us fully to explore. Sometimes even those links which we perceive are not immediately connected together; and at other times, mists, minuteness, and distance, lay an embargo upon our faculties. It is thus that the parts with which we are surrounded, are intercepted and concealed from our discernment, while the chain itself, stretching into another world, can only be discovered by that light, which, in futurity, eternity shall impart. " In the structure and organs of animals, there is an adaptation for certain ends which the most superficial observer can hardly fail to observe. Adaptation implies design, and this involves some being or power capable oi forming the design, and calculating upon is- sues, which no combination of accidents has in any known case ever yet produced. The evidences of wisdom which are scattered over the surface of our globe, speak in a language that must be heard even by the most careless and inattentive ; and the animal world pre- sents us with a noble compendium of facts, that are constantly exposed to the scrutiny of every eye. Of these, Dr. Goldsmith has fur- nished a grand exhibition; and the condi- tion of that reader is not to be envied, who, after perusing his Natural History, can close his book, and deliberately think there is no God."] 2O 214 A HISTORY OF ANXXKAX.S OF THE HORSE KIND. CHAPTER XXXVIII. OF THE HORSE.* horse kind deserve a a history of nature. ANIMALS of the place next to man, in Their activity, their strength, their usefulness, and their beauty, all contribute to render them the principal objects of our curiosity and care; a race of creatures in whose welfare we are interested next to our own. Of all the quadruped animals, the horse seems the most beautiful : the noble largeness of his form, the glossy smoothness of his skin, the graceful ease of his motions, and the exact symmetry of his shape, have taught us to re- gard him as the first, and as the most per- fectly formed ; and yet, what is extraordinary enough, if we examine him internally, his structure will be found the most different from that of man of all other quadrupeds whatso- ever. As the ape approaches us the nearest in internal conformation, so the horse is the most remote ; b a striking proof that there may be oppositions of beauty, and that all grace is not to be referred to one standard. To have an idea of this noble animal in his * As it may happen, that in a description where it is the aim rather to insert what is not usually known, than all that is known, some of the more obvious particulars may be omitted ; I will take leave to subjoin in the notes the characteristic marks of each animal, as given us by Linnaeus. " The horse, with six cutting teeth before, and single-hoofed ; a a native of Europe and the East, (but I believe rather of Africa;) a generous, proud, and strong animal ; fit either for the draught, the course, or the road : he is delighted with woods ; he takes care of his hinder parts; defends himself from the flies with his tail; scratches his fellow; defends his young ; calls by neigh- ing; sleeps after night-fall; fights by kicking, and by biting also ; rolls on the ground when he sweats; eats the grass closer than the ox ; distributes the seed by dunging; wants a gall-bladder ; never vomits ; the foal is produced native simplicity, we are not to look for him in the pastures or the stables, to which he has been consigned by man; but in those wild and extensive plains where he has been ori- ginally produced; where he ranges without control, and riots in all the variety of luxurious nature. In this state of happy independence, he disdains the assistance of man, which only tends to servitude. In those boundless tracts, whether of Africa or New Spain, where he runs at liberty, he seems no way incommoded with the inconveniences to which he is subject in Europe. The continual verdure of the fields supplies his wants; and the climate, that never knows a winter, suits his constitution, which naturally seems adapted to heat. His enemies of the forest are but few, for none but the greater kinds will venture to attack him : any one of these he is singly able to overcome ; while, at the same time, he is content to find safety in society ; for the wild horses of those countries always herd together. In these countries, therefore, the horses are with the feet stretched out; he is injured by being struck on the ear : upon the stiffle ; by being caught by the nose in barnacles; by having his teeth rubbed with tallow ; by the herb padus ; by the herb phalandria ; by the cru- culio ; by the conops. His diseases are different indif- ferent countries. A consumption of the ethmoid bones of the nose, called the glanders, is with us the most in- fectious and fatal. He eats hemlock without injury. The mare goes with foal 290 days. The placenta is not fixed. He acquires not the canine teeth till the age of five j't-ars. [ n In South America is found a horse whoso hoofs are divided, like those of a ruminant quadruped In its ge- neral appearance, size, and colour, it resembles the ass, but has the voice and ears of a horse, and has no bat.ds crossing the shoulders. It is very wild, swift, and strong.] b Histolce Naturelle, Daubenton, vol. vii. p. 374. THE HORSE. 215 often seen feeding in droves of five or six hun- dred. As they do not carry on war against any other race of animals, they are satisfied to remain entirely upon the defensive. The pas- tures on which they live, satisfy all their appetites, and all other precautions are purely for their security, in case of a surprise. As they arc never attacked but at a disadvantage, whenever they sleep in the forests, they have always one among their number that stands as centinel, to give notice of any approaching danger ; and this office they take by turns." If a man approaches them while they are feed- ing by day, their centinel walks up boldly near him, as if to examine his strength, or to intimidate him from proceeding ; but as the man approaches within pistol-shot, the centi- nel then thinks it high time to alarm his fel- lows ; this he does by a loud kind of snorting, upon which they all take the signal, and fly off with the speed of the wind ; their faithful centi- nel bringing up the rear. b It is not easy to say from what country the horse came originally. It should seem that the colder climates do not agree with his con- stitution ; for although he is found almost in them all, yet his form is altered there, and he is found at once diminutive and ill-shaped. We have the testimony of the ancients that there were wild horses once in Europe ; at present, however, they are totally brought under sub- jection ; and even those which are found in America are of a Spanish breed, which being sent thither upon its first discovery, have since become wild, and have spread over all the soutli of that vast continent almost to the straits of Magellan. These, in general, are a small br'-ed, of about fourteen hands high. They have thick jaws and clumsy joints ; their ears and neck also are long ; they are easily tamrd ; for the horse, by nature, is a gentle complying creature, and resists rather from fear than ob- stinacy. They are caught by a kind of noose, and then held fast by the legs, and tied to a tree, where they are left for two days without food or drink. By that time they begin to grow manageable ; and in some weeks they become as ta
