SABBATH. 1 IN the opening words of a Lecture delivered in this city four years ago,* I spoke of the desire and ten- dency of the present age to connect itself organically with preceding ages. The expression of this desire is not limited to the connection of the material organisms of to-day with those of the geologic past, as set forth in the doctrines of Mr. Darwin. It is equally manifested in the domain of mind. To this source may be traced the philosophical writings of Mr. Herbert Spencer. To it we are indebted for the series of learned and laborious works on * The Sources of Christianity,' by M. Renan. To it we owe the researches of Professor Max Miiller in the domain of comparative philology and mytho- logy, and the endeavour to found on these researches a * science of religion.' In this relation, moreover, the recent work of Principal Caird 3 is highly characteristic of the tendencies of the age. He has no words of vituperation for the earlier and grosser religions of the world. Throughout the ages he discerns a purpose and a growth, wherein the earlier and more imperfect religions constitute the natural and necessary precursors of the later and more perfect ones. Even in the slough 1 Presidential Address delivered before the Glasgow Sunday Society. 1 Fermentation : Fragments of Science, vol. ii. p. 233 3 Introduction to the Philosophy of Religion. 2 THE SABBATH. of ancient paganism, Principal Caird detects a power ever tending towards amelioration, ever working towards the advent of a better state, and finally emerging in the purer life of Christianity. 1 These changes in religious conceptions and practices correspond to the changes wrought by augmented ex- perience in the texture and contents of the human mind. Acquainted as we now are with this immeasur able universe, and with the energies operant therein, the guises under which the sages of old presented the Maker and Builder thereof seem to us to belorg to the utter infancy of things. To point to illustrations drawn from the heathen world would be superfluous. We may mount higher, and still find our assertion true. When, for example, Moses and Aaron, Nadab and Abihu, and seventy Elders of Israel are represented as climbing Mount Sinai, and actually seeing there the God of Israel, we Hi-ten to language to which we can attach no significance. * There is in all this,' says Principal Caird, 'much which, even when religious feeling is absorbing the latent nutriment contained in it, is perceived [by the philosophic Christian of to-day] to belong to trie domain of materialistic and figurative conception.' The reason is that the Christian philoso- pher of to-day has larger capacities and fuller knowledge than the Israelite of the time of Moses. What the one accepted as literal truth the other cannot accept save as a myth or figure. The children of Israel received without idealisation the statements of their great law- giver. To them the tables of the law were true tablets of stone, prepared, engraved, broken, and re-engraved ; while the graving tool which thus inscribed the law 1 In Prof. Jlax Miiller's Introduction to the Science of Religion Borne fine passages occur, embodying the above view of the continuity of religious development. THE SABBATH. 9 was held undoubtingly to be the finger of God. To its such conceptions are impossible. We may by habit use the words, but we attach to them no definite meaning. 'As the religious education of the world advances,' says Principal Caird, 'it becomes impossible to attach any literal meaning to those representations of God and his relations to mankind, which ascribe to Him human senses, appetites, passions, and the actions and experiences proper to man's lower and finite nature.' To Principal Caird, nevertheless, this imaging of the Unseen is of inestimable value. It furnishes an objec- tive counterpart to religious emotion, permanent but plastic capable of indefinite change and purification in response to the changing thoughts and aspirations of mankind. It is, moreover, solely on this mutable element that Principal Caird fixes his attention in estimating the religious character of individuals, or the point of pro- gress which has at any time been attained by nations or races in the religious history of the world. ' Here,' he says, Hhe fundamental inquiry is as to the objective character of their religious ideas or beliefs. The first question is, not how they feel, but what tlr j y think and believe ; not whether their religion manifests itself in emotions more or less vehement or enthusiastic, but what are the conceptions of God and divine things by which these emotions are called forth?' These con- ceptions 'of God and divine things' were, it is admitted, once ' materialistic and figurative,' and therefore objec- tively untrue. Nor is their purer essence yet distilled ; for the religious education of the world still * advances,' and is, therefore, incomplete. Hence the essentially fHixional character of that objective counterpart to religious emotion to which Principal Caird attaches most importance. He, moreover, assumes that the 4 THE SABBATH. emotion is called forth by the conception. There is doubtless action and reaction here ; but it may be questioned whether the conception, which is a construc- tion of the human understanding, could be at all put together without materials drawn from the experience of the human heart. 1 The changes of conception here adverted to have riot always been peacefully brought about. The i trans- mutation ' of the old beliefs was often accompanied by conflict and suffering. It was conspicuously so during the passage from paganism to Christianity. Some of the Roman emperors treated the Christians with fair- ness. Adrian was one of these. ' If anybody,' he says, writing to the proconsul of Asia, ' appear as accuser, and can prove that the Christians have broken the laws, let punishment be inflicted in proportion to the gravity of the offence. But, by Hercules ! if any should de- nounce a Christian slanderously, you must punish the slanderer still more severely.' This seems a very honest line for a pagan emperor to pursue. Some of his suc- cessors followed his example, but others did not. During the reign of Nero the cruelties inflicted on the Christians at Rome can hardly be mentioned without a freezing of the blood. According to Renan, the Antichrist of the Apocalypse was the Emperor Nero ; he being raised to this bad eminence by reason of his atrocities against the new religion. The mystic number 666, which Pro- testants have so often fa>tened upon the Pope, answers accurately to Nero's name and title. The numerical 1 While reading the volume of Principal Caird I was remind- d more than once of the following passage in Renan's Antechrist : ' Et. d'ailleurs. quel est 1'homme vraiment religieux qui repudie complete- ment I'enseignement traditionnel & 1'ombre duquel il sentit d'abord 1'ideal, qui ne cherche pas les conciliations, souvent impossibles, entre sa vieille foi et celle a laquelle il est arriv6 par le progres de ea pensee ? ' THE SABBATH. 5 values of the Hebrew letters added together make up this number. In his work entitled ' L'Eglise Chretienne,' Kenan describes the sufferings ot a group of Christians at Smyrna which may be taken as typical. The victims were cut up by the lash till the inner tissues of their bodies were laid bare. They were dragged mked over pointed shells. They were torn by lions ; and finally, while still alive, were committed to the flame.-:. But all these tortures failed to extract from them a murmur or a cry. A youth named Germanicus, on this occasion, gave his companions in agony an example of super- human courage. His conflict with the lions called forth such admiration that the proconsul entreated him to have mercy on his own youth. Mercy was to be obtained by recanting; but, instead of yielding, the youth pro- voked and excited the beasts, anxious to be torn to pieces, and thus removed from so perverse a world. His heroism sirnplv exasperated his brutal persecutors, who, when he was despatched, demanded another victim. The Christians were called Atheists a name then and long afterwards of terrible import. ' Death to the Atheists! let us seek Pol) carp I' shouted the maddened crowd. Polycarp, the friend of St. John, and the principal personage in the Churches of Asia, was then resident at Smyrna. They sought, found, and arrested him. Those in power tried at first to coax him into apostasy, but threats and entreaties proved equally vain. ' Insult Christ ! ' exclaimed Statins Quadratus. Polycarp replied : ' For eighty and six years have I served Him, and He has never wronged me I am a Christian ! ' The grand old man felt a profound disdain for the roaring crowd around him. * Give me a day,' said he to Quadratus, ' and I will show you what it ia to be a Christian.' * Persuade the people,' retorted 6 THE SABBATH. Quadratus. *I will reason with you, 1 replied Pqlycarp, * because our precepts oblige us to show respect to those in authority ; but I refuse to plead my cause Before a mob.' His resolution was made known to the crowd, who shouted for the lions. They were informed that for that day the teasts had finished their work. * To the flames, then ! ' cried the people ; and the aged man was led to the stake. There he publicly thanked God for admitting him amongst those who had suffered death for his name. The fate of Polycarp reminds one of that of the Jew Eleazar, described in the s-ixth chapter of the Second Book of Maccabees. The Apo- crypha, I would remark, ought to be bound up with all your Bibles; it contains much that is beautiful and wise, and there is in history nothing finer than the description of Eleazar's end. The fortitude of the early Christians gained many converts to their cause ; still, when the evidential value of fortitude is considered, it must not be forgotten that almost every faith can point to its rejoicing martyrs. Even the murderers of Polycarp had a faith of their own, the imperilling of which by Christianity spurred them on to murder. From faith they extracted the diabolical energy which animated them. The strength of laith is, therefore, no proof of the objective truth of faith. Indeed, at the very time here referred to we find two classes of Christians equally strong Jewish Christians and Gentile Christians who, while dying for the same Master, turned their backs upon each other, mutually declining all fellowship and communion. The forces which, acting on a large scale, had differen- tiated Christianity from paganism, soon made them- selves manifest in details, producing disunion and opposition among those whose creeds and interests were in great part identical. Struggles for priority, THE SABBATH. 7 moreover, were not uncommon. Jesus himself had to quell such contentions. His exhortations to humility were frequent. 'He that is least among you shall be greatest of all.' There were also conflicts upon points of doctrine. Among communities so diverse in tem- perament and antecedents differences were sure to arise. The point of difference which concerns us most had reference to the binding power of the Jewish law. Hero dissensions arose among the apostles themselves. Nobody who reads with due attention the epistles of Paul can fail to see that this mighty propagandist had to carry on a lifelong struggle to maintain his authority as a preacher of Christ. There were not wanting those who denied him all vocation. James was the head of the Church at Jerusalem, and Judeo-Christians held that the ordination of James was alone valid. Paul, therefore, having no mission from James, was deemed by some a criminal intruder. Tiie real fault of Paul was his love of freedom, and his uncompromising re- jection, on behalf of his Gentile converts, of the chains of Judaism. He proudly calls himself ' the Apostle of the Gentiles.' He .ays to the Corinthians, ' I suppose I was not a whit behind the chiefest apostle. Are they Hebrews ? So am I. Are they Israelites ? So am I. Are they of the seed of Abraham ? So am I. Are they ministers of Christ? I am more ; in labours more abundant, in s- tripes above measure, in deaths oft.' He then establishes his right to the position which he claimed by recounting in detail the sufferings he had endured. I leave it to you to compare this Christian hero with some of the * freethinkers ' of our own day, who, ' more intolerant than the intolerance they de- precate,' flaunt in public their cheap and trumpery theories of the great Apostle and the Master whom be served. 8 THE SABBATH. Paul was too outspoken to escape assault. All in- sincerity or double-facedness all humbug, in short was hateful to him ; and even among his colleagues he found scope for this feeling. Judged by our standard of manliness, Peter, in moral stature, fell far short of Paul. In that supreme moment when his Master required of him 'the durance of a granite ledge' Peter proved 'unstable as water.' He ate with the Gentiles when no Judeo-Christian was present to observe him ; but when such appeared he withdrew himself, fearing those which were of the circumcision. Paul charged him openly with dissimulation. But Paul's quarrel with Peter was more than personal. Paul contended for a principle, and was determined at all hazards to shield his Gentile children in the Lord from the yoke which their Jewish co-religionists would have imposed upon them. ' If thou,' he says to Peter, ' being a Jew, livest after the manner of the Gentiles, and not as do the Jews, why compellest thou the Gentiles to live as the Jews?' In the spirit of a liberal, not in name but in deed, he overthrew the Judaic preferences for days, deferring at the same time to the claims of conscience. ' Let him who desires a Sabbath,' he virtually says, 'enjoy it; but let him not impose it on his brother who does not.' The rift thus revealed in the apostolic lute widened with time, and Christian love was not the feeling which long animated the respective followers of Peter and Paul. We who have been born into a settled state of things can hardly realise the commotion out of which this tran- quillity has emerged. We have, for example, the canon ot Scripture already arranged for us. But to sift and select these writings from the mass of spurious docu- ments afloat at the time of compilation was a work of vast labour, difficulty, and responsibility. The age was THE SABBATH. 9 rife with forgeries. Even good men lent themselves to these pious frauds, believing that true Christian doctrine, which of course was their doctrine, would be thereby quickened and promoted. There were gospels and counter-gospels ; epistles and counter-epistles somo fiivolous, some dull, some speculative and romantic, and some so rich and penetrating, so saturated with the Master's spirit, that, though not included in the canon, they enjoyed an authority almost equal to that of the canonical books. When arguments or proofs were needed, whether on the side of the Jewish Christians or of the Gentile Christians, a document was discovered which met the case, and on which the name of an apostle, or of some authoritative contemporary of the apostles, was boldly inscribed. The end being held to sanctify the means, there was no lack of manufactured testimony. The Christian world seethed not only with apocryphal writings, but with hostile interpretations of writings not apocryphal. Then arose the sect of the Gnostics men who know who laid claim to the pos- session of a perfect science, and who, if they were to be believed, had discovered the true formula for what philosophers railed * the Absolute.' But these specula- tive Gnostics were rejected by the conservative and orthodox Christians of their day as fiercely as their successors the Agnostics men who don't know ^are rejected by the orthodox in our own. The good Polycarp one day met Marcion, an ultra-Paulite, and a celebrated member of the Gnostic sect. On being asked by Mai- cion whether he, Polycarp, did not know him, Polycarp replied, * Yes, I know you very well ; you are the first- born of the devil.' 1 This is a sample of the bitterness then common. It was a time of travail of throes and whirlwinds. Men at length began to yearn for peace 1 L'Egliie Chritlenne, p. 450. 10 TTTE SABBATH. and unity., and out of the embroilment was slowly con- solidated that great organisation the Church of Rome. The Church of Rome had its precursor in the Church at Rome. But Rome was then the capital of the world ; and, in the end, that famous city gave the Christian Church, established in her midst, such a decided pre- ponderance that it eventually laid claim to the proud title of ' Mother and Matrix of all other Churches.' With terrible jolts and oscillations the religious life of the world has run down 'the ringing grooves of change.^ A smoother route may have been undiscoverable. At all events it was undiscovered. Some years ago I found myself in discussion with a friend who entertained the notion that the general tendency of things in this world is towards equilibrium, the result of which would be peace and blessedness to the human race. My notion was that equilibrium meant not peace and blessedness, but death. No motive power is to be got from heat, save during its fall from a higher to a lower temperature, as no power is to be got from water save during its descent from a higher to a lower level. Thus also life consists, not in equilibrium, but in the passage towards equilibrium. In man it is the leap from the potential through the actual to repose. The passage often involves a fight. Every natural growth is more or less of a struggle with other growths, in which the fittest survive. In times of strife and commotion we may long for peace ; but knowledge and progress are the fruits of action. Some are, and must be, wiser than the rest; and the enuncia- tion of a thought in advance of the moment provokes dissent or evokes approval, and thus promotes action. The thought may be unwise ; but it is only by dis- cussion, checked by experience, that its value can be determined. Discussion, therefore, is one of the motive powers of life, and, as such, is not to be deprecated, THE SABBATH. 11 Still one can hardly look without despair on the passions excited, and the energies wasted, over ques- tions which, after ages of strife, are shown to be mere fatuity and foolishness. Thus the theses which shook the world during the firs-t centuries of the Christian era have, for the most part, shrunk into nothingness. It may, however, be that the human mind could not become fitted to pronounce judgment on a controversy otherwise than by wading through it. We get clear of the jungle by traversing it. Thus even the errors, con- flicts, and sufferings of bygone times may have been necessary factors in the education of the world. Let nobody, however, say that it has not been a hard educa- tion. The yoke of religion has not always been easy, nor its burden light a result arising, in part from the ignorance of the world at large, but more especially from the mistakes of those who had the charge and guidance of a great spiritual force, and who guided it blindly. Looking over the literature of the Sabbath question, as catalogued and illustrated in the laborious, able, and temperate work of the late Mr. Robert Cox, we can hardly repress a sigh in thinking of the gifts and labours of in- tellect which this question has absorbed, and the amount of bad blood which it has generated. Further reflection, however, reconciles us to the fact that waste in intellect may be as much an incident of growth as waste in nature. When the various passages of the Pentateuch which relate to the observance of the Sabbath are brought together, as they are in the excellent work of Mr. Cox, and when we pass from them to the similarly collected utterances of the New Testament, we are immediately exhilarated by a freer atmosphere and a vaster sky. Christ found the religions of the world oppressed almost to suffocation by the load of formulas piled upon them by the priesthood. He removed the load, and rendered 2 12 THE SABBATH. respiration free. He cared little for forms and ceremo- nies, which had ceased to be the raiment of man'a spiritual life. To that life he looked, and it he sought to restore. It was remarked by Martin Luther that Jesus broke the Sabbath deliberately, and even ostenta- tiously, for a purpose. He walked in the fields; he plucked, shelled, and ate the corn ; he treated the sick, and his spirit may be detected in the alleged imposition upon the restored cripple of the labour of carrying his bed on the Sabbath day. He crowned his protest against a sterile formalism by the enunciation of a principle which applies to us to-day as much as to the world in the time of Christ. ' The Sabbath was made for man, and not man for the Sabbath.' No priestly power, he virtually declares, shall henceforth interfere with man's freedom to decide how the Sabbath is to be spent. Though the Jews, to their detriment, kept them- selves as a nation intellectually isolated, the minds of individuals were frequently coloured by Greek thought and culture. The learned and celebrated Philo, who was contemporary with Josephus, was thus influenced. Philo expanded the uses of the seventh day by including in its proper observance studies which might be called secular. ' Moreover,' he says, ' the seventh day is also an example from which you may learn the propriety of studying philosophy. As on that day it is said God beheld the works that He had made, so you also may yourself contemplate the works of Nature.' Permission to do this is exactly what the members of the Sunday Society humbly claim. The Jew, Philo, would grant them this permission, but our straiter Christians will not. Where shall we find such samples of those works of Nature which Philo commended to the Sunday con- templation of his countrymen, as in the British Museum? Within those walls we have, as it were, epochs disen- THE SABBATH. 13 tombed ages of divine energy illustrated. But the efficient authorities among whom I would include a short-sighted portion of the public resolutely close the doors, and exclude from the contemplation of these things the multitudes who have only Sunday to devote to them. Are the authorities logical in doing so ? Do they who thus stand between them and the public really believe those treasures to be the work of God ? Do they or do they not hold, with Paul, that ' the eternal power and Godhead ' may be clearly seen from * the things that are made ' ? If they do and they dare not affirm that they do not I fear that Paul, with his cus- tomary plainness of language, would pronounce their conduct to be ' without excuse.' l Science, which is the logic of nature, demands pro- portion between the house and its foundation. Theology sometimes builds weighty structures on a doubtful base. The tenet of Sabbath observance is an illustration. With regard to the time when the obligation to keep the Sabbath was imposed, and the reasons for its im- position, there are grave differences of opinion between learned and pious men. Some affirm that it was insti- tuted at the Creation in remembrance of the rest of God. Others allege that it was imposed after the departure of the Israelites from Egypt, and in memory of that de- parture. The Bible countenances both interpretations. In Exodus we find the origin of the Sabbath described with unmistakable clearness, thus : ' For in six days the Lord made heaven and earth, the sea and all that in them is. Wherefore the Lord blessed the seventh day, and 1 I refer, of course, to those who object to the opening of the museums on religious grounds. The administrative difficulty stands on a different footing. But surely it ought to vanish in presence of the benefits to teas of thousands which in all probability would accrue. 14 THE SABBATH. hallowed it.' In Deuteronomy this reason is suppressed and another is assigned. Israel being a servant in Egypt, God, it is stated, brought them out of it with a mighty hand and by an outstretched arm. ' Therefore the Lord thy God commandeth thee to keep the Sabbath day.' After repeating the Ten Commandments, and assigning the foregoing origin to the Sabbath, the writer in Deuteronomy proceeds thus: 'These words the Lord spake unto all your assembly in the mount, out of the midst of the fire, of the cloud and the thick darkness, with a loud voice ; and he added no more.' But in Exodus God not only added more, but something entirely different. This has been a difficulty with commentators not formidable, if the Bible be treated as any other ancient book, but extremely formidable on the theory of plenary inspiration. I remember in the days of my youth being shocked and perplexed by an admission made by Bishop Watson in his celebrated ' Apology for the Bible,' written in answer to Tom Paine. 'You have,' says the bishop, 'disclosed a few weeds which good men would have covered up from view.' That there were 'weeds' in the Bible requiring to be kept out of sight was to me, at that time, a new revela- tion. I take little pleasure in dwelling upon the errors and blemishes of a book rendered venerable to me by intrinsic wisdom and imperishable associations. But when that book is wrested to our detriment, when its passages are invoked to justify the imposition of a yoke, irksome because unnatural, we are driven in self-defence to be critical. In self-defence, therefore, we plead these two discordant accounts of the origin of the Sabbath, one of which makes it a purely Jewish institution, while the other, unless regarded as a mere myth and figure, is in irreconcilable antagonism to the facts of geology. With regard to the alleged 'proofs' that Sunday THE SABBATH. 15 was introduced as a substitute for Saturday, and that its observance is as binding upon Christians as their Sabbath was upon the Jews, I can only say that those which I have seen are of the flimsiest and vaguest character. ' If,' says Milton, ' on the plea of a divine command, they impose upon us the observances of a particular day, how do they presume, -without the authority of a divine command, to substitute another day in its place ? ' Outside the bounds of theology no one would think of applying the term 'proofs' to the evidence adduced for the change ; and yet on this pivot, it has been alleged, turns the eternal fate of human souls. 1 Were such a doctrine not actual it would be incredible. It has been truly said that the man who accepts it sinks, in doing so, to the lowest depth of Atheism. It is perfectly reasonable for a religious community to set apart one day in seven for rest and devotion. Most of those who object to the Judaic observance of the Sabbath recognise not only the wisdom but the necessity of some such institution, not on the ground of a divine edict, but of common sense. 8 They contend, however, that it ought to be as far as possible a day of cheerful renovation both of 1 In 1785 the first mail-coach reached Edinburgh from London, and in 1788 it was continued to Glasgow. The innovation was de- nounced by a minister of the Secession Church of Scotland as ' contrary to the laws both of Church and State ; contrary to the laws of God ; contrary to the most conclusive and constraining reasons assigned by God ; and calculated not only to promote the hurt and ruin of the nation, but also the eternal damnation of mul- titudes.' Cox, vol. ii. p. 248. Even in our day there are clergymen foolish enough to indulge in this dealing out of damnation. * ' That public worship,' says Milton, ' is commended and in- culcated as a voluntary duty, even under the Gopel, I allow ; but that it is a matter of compulsory enactment, binding on believers from the authority of this commandment, or of any Sinaitical precept whatever, I deny.' 16 THE SABBATH. body and spirit, and not a day of penal gloom. There is nothing that I should withstand more strenuously than the conversion of the first day of the week into a common working day. Quite as strenuously, however, do I oppose its being employed as a day for the exercise of sacerdotal rigour. The early reformers emphatically asserted the free- dom of Christians from Sabbatical bonds ; indeed Puri- tan writers have reproached them with dimness of vision regarding the observance of the Lord's Day. ' The fourth Commandment,' says Luther, ' literally understood, does not apply to us Christians ; for it is entirely outward, like other ordinances of the Old Testament, all of which are now left free by Christ. If a preacher,' he continues, * wishes to force you back to Moses, ask him whether you were brought by Moses out of Egypt. If he says no, then say, How, then, does Moses concern me, since he speaks to the people that have been brought out of Egypt ? In the New Testament Moses comes to an end, and his laws lose their force. He must bow in the presence of Christ.' ' The Scripture,' says Melanchthon, l allows that we are not bound to keep the Sabbath ; for it teaches that the ceremonies of the law of Moses are not necessary after the revelation of the Gospel. And yet,' he adds, * because it was requisite to appoint a certain day that the people might know when to assemble together, it appeared that the Church appointed for this purpose the Lord's Day.' I am glad to find my grand old namesake on the side of freedom in this matter. ' As for the Sabbath,' says the martyr Tyndale, ' we are lords over it, and may yet change it into Monday, or into any other day, as we see need ; or may make every tenth day holy day, only if we see cause why. Neither need we any holy day at all if the people might be THE SABBATH. 17 taught without it.' Calvin repudiated 'the frivolities of false prophets who, in later times, have instilled Jewish ideas into the people. Those,' he continues, 1 who thus adhere to the Jewish institution go thrice as far as the Jews themselves in the gross and carnal superstition of Sabbatism.' Even John Knoy who has had so much Puritan strictness unjustly laid to his charge, knew how to fulfil on the Lord's Day the duties of a generous, hospitable host. His Master feasted on the Sabbath day, and he did not fear to do the same on Sunday. ' There be two parts of the Sabbath day,' says Cranmer : ' one is the outward bodily rest from all manner of labour and work ; this is mere cere- monial, and was taken away with other sacrifices and ceremonies by Christ at the preaching of the gospel. The other part of the Sabbath day is the inward rest or ceasing from sin.' This higher symbolism, as regards the Sabbath, is frequently employed by the Keformers. It is the natural recoil of the living spirit from the mechanical routine of a worn-out hierarchy. Towards the end of the sixteenth century, demands for a stricter observance of the Sabbath began to be made probably in the first instance with some reason, and certainly with good intent. The manners of the time were coarse, and Sunday was often chosen for their offensive exhibition. But if there was coarseness on the one side, there was ignorance both of Nature and human nature on the other. Contemporaneously with the demands for stricter Sabbath rules, God's judg- ments on Sabbath-breakers began to be pointed out. Then and afterwards c God's Judgments ' were much in vogue, and man, their interpreter, frequently behaved as a fiend in the supposed execution of them. But of this subsequently. A Suffolk clergyman named Bownd, who, according to Cox, was the first to set forth at large 18 THE SABBATH. the views afterwards embodied in the Westminster Confession, adduces many such judgments. One was the case of a nobleman, ' who for hunting on the holy day was punished by having a child with a head like a dog's.' Though he cites this instance, Bownd, in the matter of Sabbath observance, was very lenient towards noblemen. 'Concerning the feasts of noblemen and great personages or their ordinary diet upon this day (which in comparison may be called feasts), because they represent,' says the doctor, ' in some measure the majesty of God on the earth, in carrying the image as it were of the magnificence and puissance of the Lord, much is to be granted to them.' Imagination once directed towards this question was sure to be prolific. Instances accordingly grew apace in number and magnitude. Memorable examples of God's judgments upon Sabbath-breakers, and other like libertines, in their unlawful sports happening within this realm of England, were collected. In- numerable cases of drowning while bathing on Sunday were adduced, without the slightest attention to the logical requirements of the question. Week-day drown- ings were not dwelt upon, and nobody knew or cared how the question of proportion stood between the two classes of bathers. The Civil War was regarded as a punishment for Sunday desecration. The fire of Lon- don, and a subsequent great fire in Edinburgh, were ascribed to this cause ; while the fishermen of Berwick lost their trade through catching salmon on Sunday. Their profanation was thus nipped by a miracle in the hud, and they were brought to repentance. A Non- conformist minister named John Wells, whose huge volume is described by Cox as '-the most tedious of all the Puritan productions about the Sabbath,' is specially copious in illustration, A drunken pedlar, 'fraught THE SABBATH. 19 with commodities' on Sunday, drops into a river: God's retributive justice is seen in the fact. Wells travelled far in search of instances. One Utrich Schrce- tor, a Swiss, while playing at dice on the Lord's Bay, lost heavily, and apparently to gain the devil to his side broke out into this horrid blasphemy : ' If fortune deceive me now I will thrust my dagger in the body of God.' Whereupon he threw the dagger upwards. It disappeared, and five drops of blood, which afterwards proved indelible, fell upon the gaming table. The devil then appeared, and with a hideous noise carried off the vile blasphemer. His two companions fared no better. One was struck dead and turned into worms, the other was executed. A vintner who on the Lord's Day tempted the passers-by with a pot of wine was carried into the air by a whirlwind and never seen more. * Let us read and tremble,' adds Mr. Wells. At Tid- worth a man broke his leg on Sunday while playing at football. By a secret judgment of the Lord the wound turned into a gangrene, and in pain and terror the criminal gave up the ghost. You may smile at these recitals, but is there not a survival of John Wells still extant among you ? Are theie not people in your midst so well informed as to ' the secret judgments of the Lord ' as to be able to tell you their exact value and import, from the damaging of the share market through the running of Sunday trains to the calamitous overthrow of a railway bridge ? Alphonso of Castile boasted that if he had been con- sulted at the beginning of things he could have saved the Creator some worlds of trouble. It would not be difficult to give the God of our more rigid Sabbatarians a lesson in justice and mercy ; for his alleged judg- ments savour but little of either. How are calamities to be classified ? Almost within earshot of those who 20 THE SABBATH. note these Sunday judgments, the poor miners of Blan- tyre are blown to pieces,.while engaged in their sinless week-day toil. A little further off the bodies of two hundred and sixty workers, equally innocent of Sabbath- breaking, are entombed at Abercarne. Dinas holds its sixty bodies, while the present year has furnished a fearful tale of similar disasters. Whence comes the vision which differentiates -the Sunday calamity from the week-day calamity, seeing in the one a judgment of heaven, and in the other a natural event ? "We may wink at the ignorance of John Wells, for he lived in a prescientific age; but it is not pleasant to see his features reproduced, on however small a scale, before an educated nation in the latter half of the nineteenth century. Notwithstanding their strictness about the Sabb'ath, which possibly carried with it the usual excess of a re- action, some of the straitest of the Puritan sect saw clearly that unremitting attention to business, whether religious or secular, was unhealthy. These considered recreation to be as necessary to health as daily food ; and hence exhorted parents and masters, if they would avoid the desecration of the Sabbath, to allow to chil- dren and servants time for honest recreation on other days. They might have done well to inquire whether even Sunday devotions might not, without ' moral cul- pability ' on their part, keep the minds of children and servants too long upon the stretch. I fear many of the good men who insisted, and insist, on a Judaic observance of the Sabbath, and who dwell upon the peace and blessedness to be derived from a proper use of the Lord's Day, generalise beyond their data, applying the experience of the individual to the case of mankind. What is a conscious joy and blessing to themselves they cannot dream of as being a possible misery, or even a THE SABBATH. 21 curse, to others. It is right that your most spiritually- minded men men who, to use a devotional phrase, en- joy the closest walk with Grod should be your pastors. But they ought also to be practical men, able to look not only on their personal feelings, but on the capacities of humanity at large, and willing to make their rules and teachings square with these capacities. There is in some minds a natural bias towards religion, as there is in others towards poetry, art, or mathematics ; but the poet, artist, or mathematician who would seek to impose upon others, not possessing his tastes, the studies which give him delight, would be deemed an intolerable despot. The philosopher Fichte was wont to contrast his mode of rising into the atmosphere of faith with the experience of others. In his case the process, he said, was purely intellectual. Through reason he reached religion ; while in the case of many whom he knew this process was both unnecessary and unused, the bias of their minds sufficing to render faith, without logic, clear and strong. In making rules for the Community these natural differences must be taken into account. The yoke which is easy to the few may be intolerable to the many, not only defeating its own immediate purpose, but frequently introducing recklessness or hypocrisy into minds which a franker and more liberal treatment would have kept free from both. 1 The moods of the times the ' climates of opinion,' 1 ' When our Puritan friends,' says Mr. Frederick Robertson, talk of the blessings of the Sabbath, we may ask them to remem- ber some of its curses.' Other and more serious evils than those recounted by Mr. Robertson may, I fear, be traced to the system of Sabbath observance pursued in many of our schools. At the risk of shocking some worthy persons, I would say that the invention of an invigorating game for fine Sunday afternoons, and healthy indoor amusement for wet ones, would prove infinitely more effectual as an aid to moral purity than most of our plans of religious meditation. 22 THE SABBATH. as Glanvil calls them have also to be considered in imposing disciplines which affect the public. For the ages, like the individual, have their periods of mirth and earnestness, of cheerfulness and gloom. From this point of view a better case might be made out for the earl}' Sabbatarians than for their survivals at the pre- sent day. They were more in accord with the needs and spirit of their age. Sunday sports were barbarous ; bull- and bear-baiting, interludes, and bowling were reckoned amongst them, and the more earnest spirits longed not only to promote edification but to curb ex- cess. Sabbatarianism, therefore, though opposed, made rapid progress. Its opponents were not always wise. They did what religious parties, when in power, always do exercised that power tyrannically. They invoked the arm of the flesh to suppress or change conviction. In 1618 James I. published a declaration, known after- wards as c The Book of Sports,' because it had reference to Sunday recreations. It seems to have been, in itself, a reasonable book. Puritan magistrates had interfered with the innocent amusements of the people, and the king wished to insure their being permitted, after divine service, to those who desired them ; but not enjoined upon those who did not. Coarser sports, and sports tending to immorality, were prohibited. Charles I. renewed the declaration of his father. Not content, however, with expressing his royal pleasure not con- tent with restraining the arbitrary civil magistrate the king decreed that the declaration should be published ' through all the parish churches,' the bishops in their respective dioceses being made the vehicles of the royal command. Defensible in itself, the declaration thus became an instrument of oppression. The High Church party, headed by Archbishop Laud, forced the reading of the documents on men whose consciences recoiled THE SABBATH. 23 from the act. 'The precise clergy, as Hallam calls them, refused in general to comply, and were suspended or deprived in consequence. 'But/ adds Hallarn, * mankind loves sport as little as prayer by compulsion ; and the immediate effect of the king's declaration was to produce a far more scrupulous abstinence from diver- sions on Sundays than had been practised before.' The Puritans, when they came into power, followed the evil example of their predecessors. They, the champions of religious freedom, showed that they could, in their turn, deprive their antagonists of their benefices, fine them, burn their books by the common hangman, and compel them to read from the pulpit things of which they disapproved. On this point Bishop Heber makes some excellent remarks. 'Much,' he says, 'as each religious party in its turn had suffered from perse- cution, and loudly and bitterly as each had, in its own particular instance, complained of the severities exer- cised against its members, no party h d yet been found to perceive the great wickedness of persecution in the abstract, or the moral unfitness of temporal punishment as an engine of religious controversy.' In a very dif- ferent strain writes the Dr. Bowud who has been already referred to as a precursor of Puritanism. He is so sure of his ' doxy ' that he will unflinchingly make others bow to it. * It behoveth,' he says, ' all kings, princes, and rulers, that profess the true religion to enact such laws and to see them diligently executed, whereby the honour of God in hallowing Ihese days might be main- tained. And, indeed, this is the chiefest end of all government, that men might not profess what religion they list, and serve God after what manner it pleaseth them best, but that the parts of God's true worship [Bowndean worship] might be set up everywhere, and all men compelled to stoop unto it.' 24 THE SABBATH. There is, it must be admitted, a sad logical con- sistency in the mode of action deprecated by Bishop Heber. As long as men hold that there is a hell to be shunned, they seem logically warranted in treating lightly the claims of religious liberty upon earth. 'They dare not tolerate a freedom whose end they believe to be eternal perdition. Cruel they may be for the mo- ment, but a passing pang vanishes when compared with an eternity of pain. Unreligious men might call it hallucination, but if I accept undoubtingly the doctrine of eternal punishment, then, whatever society may think of my act, I am self-justified not only in ' letting ' but in destroying that which I hold dearest, if I believe it to be thereby stopped in its progress to the fires of hell. Hence, granting the assumptions common to both, the persecution of Puritans by High Churchmen, and of High Churchmen by Puritans, was not without a basis in reason. I do not think the question can be decided on a priori grounds, as Bishop Heber seemed to sup- pose. It is not the abstract wickedness of persecution so much as our experience of its results that causes us to set our faces against it. It has been tried, and found the most ghastly of failures. This experimental fact overwhelms the plausibilities of logic, and renders per- secution, save in its meaner and steal thier aspects, in our day impossible. The combat over Sunday continued, the Sabbatarians continually gaining ground. In 1643 the divines who drew up the famous document known as the Westminster Confession began their sittings in Henry VII. 's Chapel. Milton thought lightly of these divines, who, he said, were sometimes chosen by the whim of members of Parliament ; but the famous Puritan, Baxter, extolled them for their learning, godliness, and ministerial abilities. A journal of their earlier proceedings was THE SABBATH. 25 kept by Lightfoot, one of their members. On November 1 3, 1 644, he records the occurrence of * a large debate ' on the sanctification of the Lord's Day. After fixing the introductory phraseology, the assembly proceeded to consider the second proposition : ' To abstain from all unnecessary labours, worldly sports, and recreations.' It \vas debated whether ' worldly thoughts ' should not be added. ' This was scrupulous,' says the naive journalist, * whether we should not be a scorn to go about to bind men's thoughts, but at last it was concluded upon to be added, both for the more piety and for the Fourth Commandment.' The question of Sunday cookery was then discussed and settled ; and, as regards public worship, it was decreed ' that all the people meet so timely that the whole congregation be present at the beginning, and not depart until after the blessing. That what time is vacant between or after the solemn meetings of the congregation be spent in reading, medi- tation, repetition of sermons,' &c. These holy men were full of that strength already referred to as imparted by faith. They needed no natural joy to brighten their lives, mirth being displaced by religious exaltation. They erred, however, in making themselves a measure for the world at large, and insured the overthrow of their cause by drawing too heavily upon average human nature. * This much,' says Hullam, * is certain, that when the Puritan party employed their authority in proscribing all diversions, and enforcing all the Jewish rigour about the Sabbath, they rendered their own yoke intolerable to the young and gay ; nor did any other cause, perhaps, so materially contribute to bring about the Restoration.' From the records of the Town Council of Edinburgh, Mr. Cox makes certain extracts which amusingly illus- trate both the character of Sabbath discipline and the 26 THE SABBATH. difficulty of enforcing it. In 1560 it was, among other things, decreed that on Sundays ' all persous be astricted to be present at the ordinary sermons, as well after noon as before noon, and that from the last jow of the bell to the said sermons to the final end.' In 1581 the Council ordained that ' proclamation be made through this burgh, discharging all kinds of games and plays now commonly used the said day, such as bowling in yards, dancing, playing, running through the high street of hussies, bairns, and boys, with all manner of dissolution of behaviour.' The people obeyed and went to church, but it seems they chose their own preachers. This galavanting among the kirks was, however, quickly put an end to; for in 1584 it was ordained 'that all freemen and freemen's wives in times coming be found in their own parish kirk every Sunday, as also at the time of the Communions, under the pain of payment of an unlaw for every person being found absent.' In 1586 the Council ' finds it expedient that a bailie ilk Sunday his week about, visit the street taverns and other com- mon places in time of sermon, and pones all offenders according to the town statutes.' Vaging (strolling) in the High Gate was also forbidden. These restrictions, applying at first to the time of divine service only, were afterwards extended to the entire Sunday ; but sabbath profanation resembled hy- draulic pressure, and broke forth whenever it found a weak point in the municipal dam. The repairing and strengthening of the dam were incessant. Proclamation followed proclamation, forbidding the practice of buying and selling, the opening of eating- and coffee-houses, and prohibiting such sports as golf, archery, row-bowles, penny-stone, and kaitch-pullis. The gates of the city were ordered to be closed on Saturday night and not to be opened before four o'clock on Monday morning. At THE SABBATH. 27 the time these edicts were published the Provost com- plained of the little obedience hitherto given to the manifold acts of council for keeping the Sabbath. A decree on January 14, 1659, runs thus: ' Whereas many both young and old persons walk, or sit and play on the Castle hill, and upon the streets and other places on the Sabbath day after sermons, so that it is manifest that family worship is neglected by such, the Council appoint that there be several pairs of stocks provided to stand in several public places of the city, that whosoever is needlessly walking or sitting idly in the streets shall either pay eighteen-pence ster- ling penalty or be put in the stocks.' The parents of children found playing are fined 6d. a head. * And if any children be found on the Castle hill after supper to pay I8d. penalty or to be put in the stocks.' Even this drastic treatment did not cure the .evil, for thirty years later the edict against ' vaging ' on the Castle hill had to be renewed. At the same time it was ordered that the public wells be closed on Sunday from 8 A.M. till noon ; then to open till 1 P.M., and afterwards from 5 P.M. None to bring any greater vessels to the wells for the carrying of water than a pint stoup or a pint bottle on the Lord's Day. Our present sanitary .notions were evidently not prevalent in Edinburgh in 1689. Mr. Cox remarks that ' these ordinances were usually enacted at the in- stance of the clergy.' It would have been well had the evils which the clergy inflicted on the world at the time here referied to been limited to the stern manipu- lation of Sabbath laws. 1 1 In Massachusetts it was attempted to make Sabbath-breaking a capital offence, but Governor Winthrop had the humanity and good sense to erase it from the list of acts punishable with death. In the laws of the colony of New Plymouth, presumptuous Sabbath- 3 28 THE SABBATH. In 1646 the * Confession,' after * endless janglings/ being agreed upon, it was presented to Parliament, which, in 1648, accepted and published its doctrinal portion, thus securing uniformity of doctrine as far aa it could be secured by legislation. There was no lack of definiteness in the Assembly's statements. They spoke as confidently of the divine enactments as if each member had been personally privy to the counsels of the Most High. When Luther in the Castle of Marburg had had enough of the arguments of Zuin- glius on the * real presence,' he is said to have ended the controversy by taking up a bit of chalk and writing firmly and finally upon the table ' Hoc est corpus meum.' Equally downright and definite .were the divines at Westminster. They were modest in offering their conclusions to Parliament as 'humble advice,' but there was no flicker of doubt either in their theo- logy or their cosmology. * From the beginning of the world,' they say, 'to the Resurrection of Christ the last day of the week was kept holy as a Sabbath; ' while from the Resurrection it ' was changed into the first day of the week, which in Scripture is called the Lord's Day, and is to be continued to the end of the world as the Christian Sabbath.' The notions of the divines, regarding the ' beginning and the end ' of the world, were primitive, but decided. An ancient philosopher was once mobbed for venturing the extravagant opinion that the sun, which appeared to be a circle less than a yard in diameter, might really be as large as the whole country of Greece. Imagine a man with the know- ledge of a modern geologist lifting up his voice among these Westminster divines ! ' It pleased Grod,' they continue, ' at the beginning, to create, or make of breaking was either followed by death or ' grievously punished at the judgment of the court.' THE SABBATH. 29 nothing, the world and all things therein, whether visible or invisible, in the space of six days, and all very good.' Judged from our present scientific stand- point this, of course, is mere nonsense. But the calling of it by this name does not exhaust the question. The real point of interest to me, I confess, is not the cos- mological errors of the Assembly, but the hold which theology has taken of the human mind, and which enables it to survive the ruin of what was long deemed essential to its stability. On this question of ' essen- tials ' the gravest mistakes are constantly made. Save as a passing form no part of objective religion is essen- tial. It is, as already shown, in its nature fluxional. Posterity will refuse to subscribe to the Nicene creed. Eeligion lives not by the force and aid of dogma, but because it is ingrained in the nature of man. To draw a metaphor from metallurgy, the moulds have been broken and reconstructed over and over again, but the molten ore abides in the ladle of humanity. An influ- ence so deep and permanent is not likely soon to dis- appear ; but of the future form of religion little can be predicted. Its main concern may possibly be to purify, elevate, and brighten the life that now is, instead of treating it as the more or less dismal vesti- bule of a life that is to come. The term 'nonsense,' which has been just applied to the views of creation enunciated by the Westminster Assembly, is u.sed, as already stated, in reference to our present knowledge and not to the knowledge of three or four centuries ago. To most people the earth was at that time all in all ; the sun and moon and stars being set in heaven merely to furnish lamplight to our planet. But though in relation to the heavenly bodies the earth's position and importance were thus exagger- ated, very inadequate and erroneous notions were 30 THE SABBATH. entertained regarding the shape and magnitude of the earth itself. Theologians were horrified when first informed that our planet was a sphere. The question of antipodes exercised them for a long time, most cf them pouring ridicule on the idea that men could exist with their feet turned towards us, and with their heads pointing downwards. I think it was Sir George Airy who referred to the case of an over-curious individual, asking what we should see if we went to the edge of the world and looked over. That the earth was a flat surface on which the sky rested was the belief enter- tained by the founders of all our great religious systems. The growth of the Copernican theory in public favour filled even liberal Protestant theologians with apprehension. They stigmatised it as being * built on fallible phenomena and advanced by many arbitrary assumptions against evident testimonies of Scripture.' ' Newton finally placed his intellectual crowbar beneath these ancient notions, and heaved them into irretriev- able ruin. Then it was that penetrating minds among the theologians, seeing the nature of the change wrought by the new astronomy in our conceptions of the uni- verse, also discerned the difficulty, if not the impossi- bility, of accepting literally the Mosaic account of creation. With characteristic tenacity they clung to that account, but they assigned to it a meaning entirely new. Dr. Samuel Clarke, who was the personal friend of Newton and a supporter of his theory, threw out the idea that ( possibly the six days of creation might be a typical representation of some greater periods.' Clarke's contemporary, Dr. Thomas Burnet, wrote with greater decision in the same strain. The Sabbath being 1 Such was the view of Dr. John Owen, who is described by Cox uu ' the most eminent of the Independent divines.' THE SABBATH. 31 regarded as a shadow or type of that heavenly repose which the righteous will enjoy when this world has passed away, ' so these six days of creation are so many periods or millenniums for which the world and the toils and labours of our present state are destined to endure.' l The Mosaic account was thus reduced to a poetic myth a view which afterwards found expression in the vast reveries of Hugh Miller. But if this sym- bolic interpretation, which is now generally accepted, be the true one, what becomes of the Sabbath day ? It is absolutely without ecclesiastical meaning. The man who was executed for gathering sticks on that day must therefore be regarded as the victim of a rude legal rendering of a religious epic. There were many minor offshoots of discussion from the great central controversy. Bishop Horsley had defined a day * as consisting of one evening and one morning, or, as the Hebrew words literally import, of the decay of light and the return of it.' But what then, it was asked, becomes of the Sabbath in the Arctic regions, where light takes six months to ' decay,' and as long to l return ' ? Differences of longitude, moreover, render the observance of the Sabbath at the same hours impossible. To some people such ques- tions might appear trifling ; to others they were of the gravest import. Whether the Sabbath should stretch from sunset to sunset, or from midnight to midnight, was also a subject of discussion. ' If it should begin at midnight,' says one writer, ' what man of a thousand can readily tell the certain time when it begins, that so they may in a holy manner begin the Sabbath with God ? All men have not the midnight clocks and bells to awaken them, nor can the crowing of cocks herein 1 Cox, vol. ii. p. 211, note. 32 THE SABBATH. give a certain sound. A poor Christian man had need to be a good and watchful mathematician that holds this opinion, or else I see not how he will know when midnight is come.' In 1590 the Presbytery of Glasgow enjoined that the Sabbath should be ' from sun to sun.' In 1640 the Sabbath was declared to extend from mid- night to midnight. Uncertainty reigned, and innocent people were prosecuted for beginning to work imme- diately after sunset. Already, prior to the date last mentioned, voices were heard refusing to acknowledge the propriety of the change from Saturday to Sunday, and the doctrine of Seventh Day observance was after- wards represented by a sect. 1 The earth's sphericity and rotation, which had at first been received with such affright, came eventually to the aid of those afflicted with qualms and difficulties regarding the respective claims of Saturday and Sunday. The sun moves apparently from east to west. Suppose then we start on a voyage round the world in a westerly direc- tion. In doing so we sail away, as it were, from the sun, which follows and periodically overtakes us, reach- ing the meridian of our ship each succeeding day somewhat later than if we stood still. For every 15 of longitude traversed by the vessel the sun will be exactly an hour late ; and after the ship has traversed 1 Theophilus Brabourne, a sturdy Puritan minister of Norfolk, whom Cox regards as the founder of this sect, thus argued the ques- tion in 1(!28 : ' A.nd now let me propound unto your choice these two days : the Sabbath-day on Saturday or the Lord's Day on Sunday ; and keep whether of the twain you shall in conscience find the more safe. If you keep the Lord's Day, but profane the Sabbath Day, you walk in great danger and peril (to say the least) of transgressing one of God's eternal and inviolable laws the Fourth Commandment. But, f GOETHE'S ' FARBENLEHRE.' 49 a work which exerted so great an influence in its day, 1 I have not shrunk from the labour of such a review. The average reading of the late Mr. Buckle is said to have amounted to three volumes a day. They could not have been volumes like those of the ' Farbenlehre. For the necessity of halting and pondering over its statements is so frequent, and the difficulty of coming to any undoubted conclusion regarding Groethe's real conceptions is often so great, as to invoke the expendi- ture of an inordinate amount of time. I cannot even now say with confidence that I fully realise all the thoughts of Gfoethe. Many of them ate strange to the scientific man. They demand for their interpretation a sympathy beyond that required, or even tolerated, in severe physical research. Two factors, the one external and the other internal, go to the production of every in- tellectual result. There is the evidence without, and there is the mind within on which that evidence im- pinges. Change either factor and the result will cease to be the same. In the region of politics, where mere opinion comes so much into play, it is only natural that the same external evidence should produce different convictions in different minds. But in the region of science, where demonstration instead of opinion is paramount, such differences ought hardly to be ex- pected. That they nevertheless occur is strikingly exem- plified by the case before us ; for the very experimental facts which had previously converted the world to Newton's views, on appealing to the mind of Groethe, produced a theory of light and colours in violent anta- gonism to that of Newton. 1 The late Sir Charles Eastlake translated a portion of the Farbcrilelire ; while the late Mr. Lewes, in his Life of Goethe, has given a brief but very clever account of the work. It is also dealt with by Dove and, in connection with Goethe's other scientific labours, by Helmholtz. 50 GOETHE'S ' FARBENLEHRE.' Goethe prized the * Farbenlehre ' as the most import- ant of his works. * In what I have done as a poet,' he says to Eckermann, * I take no pride, but I am proud of the fact that I am the only person in this century who is acquainted with the difficult science of colours.' If the importance of a work were to be measured by the amount of conscious labour expended in its production, Goethe's estimate of the ' Farbenlehre ' would probably be correct. The observations and experiments there recorded astonish us by their variety and number. The amount of reading which he accomplished was obviously vast. He pursued the history of optics not only along its main streams, but on to its remotest rills. He was animated by the zeal of an apostle, for he believed that a giant imposture was to be overthrown, and that he was the man to accomplish the holy work of destruction. He was also a lover of art, and held that the enunciation of the true principles of colour would, in relation to painting, be of lasting importance. Thus positively and negatively he was stimulated to bring all the strength he could command to bear upon this question. The greater part of the first volume is taken up with Goethe's own experiments, which are described in 920 paragraphs duly numbered. It is not a consecutive argument, but rather a series of jets of fact and logic emitted at various intervals. I picture the poet in that troublous war-time, walking up and down his Weimar garden, with his hands behind his back, pondering his subject, throwing his experiments and reflections into these terse paragraphs, and turning occasionally into his garden house to write them down. This first por- tion of the work embraces three parts, which deal, re- spectively, with Physiological or Subjective Colours, with Physical or Prismatic Colours, and with Chemical Colours and Pigments. To these are added a fourth part, bearing the German title, ' Allgemeine Ansichten GOETHE'S ' FARBENLEHRE.' 51 naeh innen ; ' a fiftli part, entitled * Nachbarliche Ver- haltnisse,' neighbouring relations ; and a sixth part, entitled ' Sinnlich-sittliche Wirkung der Farbe,' sen- suously-moral effect of colours. It is hardly necessary to remark that some of these titles, though doubtless preg- nant with meaning to the poet himself, are not likely to commend themselves to the more exacting man of science. The main divisions of Goethe's book are subdivided into short sections, bearing titles more or less shadowy from a scientific point of view Origin of white ; Origin of black ; Excitement of colour ; Heightening ; Culmina- tion ; Balancing ; Reversion ; Fixation ; Mixture real ; Mixture apparent ; Communication actual ; Communi- cation apparent. He describes the colours of minerals, plants, worms, insects, fishes, birds, mammals, and men. Hair on the surface of the human body he con- siders indicative rather of weakness than of strength. The disquisition is continued under the headings How easily colour arises ; How energetic colour may be ; Heightening to red ; Completeness of manifold pheno- mena ; Agreement of complete phenomena ; How easily colour disappears ; How durable colour remains ; Relation to philosophy ; Relation to mathematics ; Relation to physiology and pathology ; Relation to natural history ; Relation to general physics ; Relation to tones. Then follows a series of sections dealing with the primary colours and their mixtures. These sections relate less to science than to art. The writer treats, among other things, of ^Esthetic effects Fear of the Theoretical: Grounds and Pigments, Allegorical, Symbolical, and Mystical use of colours. The headings alone indicate the enormous industry of the poet ; showing at the same time an absence of that scientific definition which he stigmatised as ' pedantry ' in the case of Newton. 52 GOETHE'S ' FARBENLEHRE.' In connection with his subject, Goethe charged himself with all kinds of kindred knowledge. He refers to ocular spectra, quoting Boyle, Butfon, and Darwin ; to the paralysis of the eye by light ; to its extreme sensitiveness when it awakes in the morning; to irradia- tion quoting Tycho Brahe on the comparative apparent size of the dark and the illuminated moon. He dwells upon the persistence of impressions upon the retina, and quotes various instances of abnormal duration. He possessed a full and exact knowledge of the phenomena of subjective colours, and described various modes of producing them. He copiously illustrates the produc- tion by red of subjective green, and by green of subjec- tive red. Blue produces subjective yellow, and yellow subjective blue. He experimented upon shadows, coloured in contrast to sui rounding light. The con- trasting subjective colours he calls 'geforderte Far- ben,' colours ' demanded ' by the eye. Goethe gives the following striking illustration of these subjective effects. 'I once,' he said, 'entered an inn towards evening, when a well-built maiden, with dazzlingly white face, black hair, and scarlet bodice and skirt came towards me. I looked at her sharply in the twilight, and when the moved away, saw upon the white wall opposite, a black face with a bright halo round it, while the clothing of the perfectly distinct figure appeared of a beautiful sea-green.' With the instinct of the poet, Goeihe discerned in these antitheses an image of the general method of nature. Every action, he says, implies an opposite. Inhalation precedes expiration, and each systole has its corresponding diastole. Such is the eternal formula of life. Under the figure of systole and diastole the rhythm of nature is represented in other portions of his work. Goethe handled the prism with great skill, and hi 1 * GOETHE'S ' FARBENLEHRE.' 63 experiments with it are numberless. He places white rectangles on a black ground, black rectangles on a white ground, and shifts their apparent positions by prismatic refraction. He makes similar experiments with coloured rectangles and discs. The shifted image is sometimes projected on a screen, the experiment l>eing then ' objective.' It is sometimes looked at directly through the prism, the experiment being then 'subjective.' In the production of chromaiic effects, lie dwells upon the absolute necessity of boundaries * Granzen.' The sky may be looked at and shifted by a prism without the production of colour; and if the white rectangle on a black ground be only made wide enough, the centre remains white after refraction, the colours being confined to the edges. Goethe's earliest experiment, which led him so hastily to the conclusion that Newton's theory of colours was wrong, consisted in looking through a prism at the white wall of his own room. He expected to see the whole wall covered with colours, this being, he thought, implied in the theory of Newton. But to his astonishment it remained white, and ouly when he came to the boundary of a dark or a bright space did the colours reveal themselves. This question of * boundaries' is one of supreme importance to the author of the ' Farbenlehre ; ' the end and aim cf his theory being to account for the coloured fringes produced at the edges of his refracted images. Darkness, according to Goethe, had as much to do as light with the production of colour. Colour was really due to the commingling of both. Not only did his white rectangles upon a black ground yield the coloured fringes, but his black rectangles on a white ground did the same. The order of the colours seemed, however, different in the two cases. Let a visiting card, Lcld in the hand between the eye and a window facing 54 GOETHE'S ' FARBENLEHRE.' the bright firmament, be looked at through a prism ; then supposing the image of the card to be shifted upwards by refraction, a red fringe is seen above and a blue one below. Let the back be turned to the window and the card so held that the light shall fall upon it ; on being looked at through the prism, blue is seen above and red below. In the first case the fringes are due to the decomposition of the light adjacent to the edge of the card, which simply acts as an opaque body, and might have been actually black. In the second case the light decomposed is that coming from the surface of the card itself. The first experiment corresponds to that of Goethe with a black rectangle on a white ground ; while the second experiment corresponds to Goethe's white rectangle on a black ground. Both these effects are immediately deducible from Newton's theory of colours. But this, though explained to him by physicists of great experience and reputation, Goethe could never be brought to see, and he continued to affirm to the end of his life that the results were utterly irreconcilable with the theory of Newton. In his own explanations Goethe began at the wrong end, inverting the true order of thought, and trying to make the outcome of theory its foundation. Apart from theory, however, his observations are of great interest and variety. He looked to the zenith at mid- night, and found before him the blackness of space, while in daylight he saw the blue firmament overhead ; and he rightly adopted the conclusion that this colour- ing of the sky was due to the shining of the sun upon a turbid medium with darkness behind. He by no means understood the physical action of turbid media, but he made a great variety of experiments bearing upon this point. Water, for example, rendered turbid by varnish, soap, or milk, and having a black ground GOETHE'S ' FARBENLEHRE.' 5 behind it, always appeared blue when shone upon by white light. When, instead of a black background, a bright one was placed behind, so that the light shone, not on but through the turbid liquid, the blue colour disappeared, and he had yellow in its place. Such experiments are capable of endless variation. To this class of effects belongs the painter's * chill.' A cold bluish bloom, like that of a plum, is sometimes observed to cover the browns of a varnished picture. This is due to a want of optical continuity in the varnish. Instead of being a coherent layer it is broken up into particles of microscopic smallness, which virtually con- stitute a turbid medium and send blue light to the eye. Goethe himself describes a most amusing illustra- tion, or, to use his own language, ' a wonderful pheno- menon,' due to the temporary action of a turbid medium on a picture. ' A portrait of an esteemed theologian was painted several years ago by an artist specially skilled in the treatment of colours. The man stood forth in his dignity clad in a beautiful bLck velvet coat, which attracted the eyes and awakened the admiration of the beholder almost more than the face itself. Through the action of humidity and dust, however, the picture had lost much of its original splendour. It was there- fore handed over to a painter to be cleaned, and newly varnished. The painter began by carefully passing a wet sponge over the picture. But he had scarcely thus removed the coarser dirt, when to his astonishment the black velvet suddenly changed into a light blue plush : the reverend gentleman acquiring thereby a very worldly, if, at the same time, an old-fashioned appearance. The painter would not trust himself to wash further. He could by no means see how a bright blue could under- lie a dark black, still less that he could have so rapidly 56 GOETHE'S ' FARBENLEHRE.' washed away a coating capable of converting a blue like that before him into the black of the original painting.' Groethe inspected the picture, saw the phenomenon, and explained it. To deepen the hue of the velvet coat the painter had covered it with a special varnish, which, by absorbing part of the water passed over it, was con- verted into a turbid medium, through which the black behind instantly appeared as blue. To the great joy of the painter, he found that a few hours' continuance in a dry place restored the primitive black. By the evaporation of the moisture the optical continuity of the varnish (to which essential point Goethe does not refer) was re-established, after which it ceased to act as a turbid medium. This question of turbid media took entire possession of the poet's mind. It was ever present to his observa- tion. It was illustrated by the azure of noonday, and by the daffodil and crimson of the evening sky. The illimitable lines written at Ilmenau Ueber alien Gipfeln 1st Rub', In alien Wipfeln Sparest Du Kaum einen Hauch suggest a stillness of the atmosphere which would allow the columns of fine smoke from the foresters' cottages to rise high into the air. He would thus have an opportunity of seeing the upper portion of the column projected against bright clouds, and the lower portion against dark pines, the brownish yellow of the one, and the blue of the other, being strikingly and at once revealed. He was able to produce artificially at will the colours which he had previously observed in nature. GOETHE'S ' FARBENLEHRE. 1 57 lie noticed that when certain bodies were incorporated with glass this substance also played a double part, appearing blue by reflected and yellow by transmitted light. 1 The action of turbid media was to Goethe the ulti- mate fact the Urphanomen of the world of colours* * We see on the one side Light and on the other side Darkness. We bring between both Turbidity, and from these opposites develop all colours.' As long as Goethe remains in the region of fact his observations are of permanent value. But by the coercion of a powerful imagination he forced his turbid media into regions to which they did not belong, and sought to overthrow by their agency the irrefragable demonstra- tions of Newton. Newton's theory, as known by every- body, is that white light is composed of a multitude of differently refrangible rays, whose coalescence produces the impression of white. By prismatic analysis these rays are separated from each other, the colour of each ray being strictly determined by its refrangibility. The experiments of Newton, whereby he sought to establish this theory, had long appealed with overmastering evi- dence to every mind trained in the severities of physical investigation. But they did not thus appeal to Goethe. Accepting for the most part the experiments of Newton, he rejected with indignation the conclusions drawn from them, and turned into utter ridicule the notion that white light possessed the composite character ascribed to it. Many of the naturalists of his time supported him, while among philosophers Schelling and Hegel shouted in acclamation over the supposed defeat of Newton. The physicists, however, gave the poet no countenance. Goethe met their scorn with scorn, and 1 Beautiful and instructive samples of such glass are to be seen in the Venice Glass Company's shop, No. 30 St. James's Street. 58 GOETHE'S 'FARBENLEHRE.' under his lash these deniers of his theory, their Master included, paid the penalty of their arrogance. How, then, did he lay down the lines of his own theory ? How, out of such meagre elements as his yellow, and his blue, and his turbid medium, did he extract the amazing variety and richness of the New- tonian spectrum ? Here we must walk circumspectly, for the intellectual atmosphere with which Groe^he sur- rounds himself is by no means free from turbidity. In trying to account for his position, we must make our- selves acquainted with his salient facts, and endeavour to place our minds in sympathy with his mode of regard- ing them. He found that he could intensify the yellow of his transmitted light by making the turbidity of his medium stronger. A single sheet of diaphanous parch- ment placed over a hole in his window-shutter appeared whitish. Two sheets appeared yellow, which by the addition of other sheets could be converted into red. It is quite true that by simply sending it. through a me- dium charged with extremely minute particles we can extract from white light a ruby red. The red of the London sun, of which we have had such fine and fre- quent examples during the late winter, is a case to some extent in point. Groethe did not believe in New- ton's differently refrangible rays. He refused to enter- tain the notion that the red light obtained by the employment of several sheets of parchment was different in quality from the yellow light obtained with two. The red, according to him, was a mere intensification ' Steigerung ' of the yellow. Colours in general con- sisted, according to Goethe, of light on its way to darkness, and the only difference between yellow and red consisted in the latter being nearer than the former to its final goal. But how in the production of the spectrum do tur- GOETHE'S ' tfAKBESLEHRE.' 59 bid media come into play ? If they exist, where are they ? The poet's answer to this question is subtle in the extreme. He wanders round the answer before he touches it, indulging in various considerations regarding penumbrse and double images, with the apparent aim of breaking down the repugnance to his logic which the mind of his reader is only too likely to entertain. If you place A white card near the surface of a piece of plate-glass, and look obliquely at the image of the card reflected from the two surfaces, you observe two images, which are hazy at the edges and more dense and defined where they overlap. These hazy edges Goethe pressed into his service as turbid media. He fancied that they associated themselves indissolubly with his refracted rectangles that in every case the image of the rectangle was accompanied by a secondary hazy image, a little in "advance of the principal one. At one edge, he contended, the advanced secondary imnge had black behind it, which was converted into blue ; while at the other edge it bad white behind it, and appeared yellow. When the refracted rectangle is made very narrow, the fringes approach each other and finally overlap. Blue thus mingles with yellow, and the green of the spectrum is the consequence. This, in a nutshell, is the theory of colours develorei in the ' Farbenlehre.' Goethe obviously regarded the narrowing of the rectangle, of the cylindrical beam, or of the slit from which the light passed to the prism according to Newton the indispensable requisite for the production of a pare spectrum as an impure and complicated mode of illustrating the phenomenon. The elementary fact is, according to Goethe, obtained when we operate with a wide rectangle the edges only of which are coloured by refraction, while the centre remains white. His experiments with the parchment 60 aOETHE'S ' FAEBENLEHEE. 1 had made him acquainted with the passage of yellow into red as he multiplied his layers ; but how this pas- sage occurs in the spectrum he does not explain. That, however, his hazy surfaces his virtual turbid media. produced, in some way or other, the observed passage and intensification, Goethe held as firmly, and enun- ciated as confidently, as if his analysis of the phenomena had been complete. The fact is, that between double images and turbid media there is no kinship whatever. -Turbidity is due to the diffusion, in a transparent medium, of minute particles having a refractive index different from that of the medium. But the act of reflection, which pro- duced the penumbral surfaces, whose aid Goethe in- voked, did not charge them with such discrete particles. On various former occasions I have tried to set forth the principles on which the chromatic action of turbid media depends. When such media are to be seen blue, the light scattered by the diffused particles, and that only, ought to reach the eye. This feeble light may be compared to a faint whisper which is easily rendered inaudible by a louder noise. The scattered light of the particles is accordingly overpowered, when a stronger light comes, not from the particles, but from. a bright surface behind them. Here the light reaches the eye, minus that scattered by the particles. It is therefore the complementary light, or yellow. Both effects are immediately deducible from the principles of the un- dulatory theory. As a stone in water throws back a larger fraction of a ripple than of a larger wave, so do the excessively minute particles which produce the turbidity scatter more copiously the small waves of the spectrum than the large ones. Light scattered by such particles will therefore always contain a preponderance of the waves which produce the sensation of blue. GOETHE'S ' FARBENLEHEE.' 61 During its transmission through the turbid medium ihe white light is more and more robbed of its blue constituents, the transmitted light which reaches the eye being therefore complementary to the blue. Some of you are, no doubt, aware that it is possible to take matter in the gaseous condition, when its smallest parts are molecules, incapable of being either seen themselves or of scattering any sensible portion of light which impinges on them ; that it is possible to shake these molecules asunder by special light- waves, so that their liberated constituents shall coalesce anew and form, not molecules, but particles ; that it is po=sible to cause these particles to grow, from a size bordering on the atomic, to a size which enables them to copiously scatter light. Some of you are aware that in the early stages of their growth, when they are still beyond the grasp of the microscope, such particles, no matter what the substance may be of which they are composed, shed forth a pure firmamental blue ; and that from them we can manufacture in the laboratory artificial skies which display all the phenomena, both of colour and polarisation, of the real firmament. With regard to the production of the green of the spectrum by the overlapping of yellow and blue, Goethe, like a multitude of others, confounded the mixture of blue and yellow lights with that of blue and yellow pigments. This was an error shared by the world at large. But in Goethe's own day, Wiinsch of Leipzig, who is ridiculed in the ' Farbenlehre,' had corrected the error, and proved the mixture of blue and yellow lights to produce white. Any doubt that might be entertained of Wiinsch's experiments and they are obviously the work of a careful and compe- tent man is entirely removed by the experiments of Helmholtz and others in our own day. Thus, to sum 62 GOETHE'S ' FARBENLEHRE,' up, Goethe's theory, if such it may be called, proves incompetent to account even approximately for the Newtonian spectrum. He refers it to turbid media, but no such media come into play. He fails to account for the passage of yellow into red and of blue into violet ; while his attempt to deduce the green of the spectrum from the mixture of yellow and blue, is contradicted by facts which were extant in his own time. One hole Goethe did find in Newton's armour, through which his lance incessantly worried the Eng- lishman. Newton had committed himself to the doc- trine that refraction without colour was impossible. He therefore thought that the object-glasses of tele- scopes must for ever remain imperfect, achromatism and refraction being incompatible. The inference of Newton was proved by Dollond to be wrong. 1 With the same mean refraction, flint glass produces a longer and richer spectrum than crown glass. By diminishing the refracting angle of the flint-glass prism, its spec- trum may be made equal in length to that of the crown glass. Causing two such prisms to refract in opposite directions, the colours may be neutralised, while a con- siderable residue of refraction continues in favour of the crown. Similar combinations are possible in the case of lenses; and hence, as Dollond showed, the possibility of producing a compound achromatic lens. Here, as elsewhere, Goethe proves himself master of the experimental conditions. It is the power of in- terpretation that he lacks. He flaunts this error re- garding achromatism incessantly in the face of Newton and his followers. But the error, which was a real one, 1 Dollond was the son of a Huguenot. Up to 1752 he was a silk weaver at Spitalfields ; he afterwards became an optician. GOETHE'S ' FARBENLEHRE.' 63 leaves Newton's theory of colours perfectly unim- paired. Newton's account of his first experiment with the prism is for ever memorable. ' To perform my late promise to you,' he writes to Oldenburg, ' I shall with- out further ceremony acquaint you, that in the year lt)66 (at which time I applied myself to the grinding of optick-glasses of other figures than spherical) I pro- cured me a triangular glass prism, to try therewith the celebrated phenomena of colours. And in order thereto, having darkened my chamber, and made a small hole in my window-shuts, to let in a convenient quantity of the sun's light, I placed* my prism at its entrance, that it might be thereby refracted to the opposite wall. It was at first a very pleasing divertisement, to view the vivid and intense colours produced thereby ; but after a while applying myself to consider them more circum- spectly, I became surprised to see them in an oblong form, which according to the received laws of refrac- tions, I expected should have been circular. They were terminated at the sides with straight lines, but at the ends the decay of light was so gradual, that it was difficult to determine justly what was their figure, yet they seemed semi-circular. ' Comparing the length of this coloured spectrum with its breadth, I found it about five times greater ; a disproportion so extravagant, that it excited me to a more than ordinary curiosity of examining from whence it might proceed.' This curiosity Newton gratified by instituting a series of experimental questions, the answers to which left no doubt upon his mind that the elongation of his spectrum was due to the fact ' that light is not similar or homogeneal, but consists of difforni rays, some of which are more refrangible than others ; so that, without any difference in their 64 GOETHE'S ' FAKBENLEHRE.' incidence on the same medium, some shall be more refracted than others; and therefore that, according to their particular degrees of refrangibility, they were transmitted through the prism to divers parts of the opposite wall. When,' continues Newton, ' I under- stood this, I left off my aforesaid glass works ; for I saw that the perfection of telescopes was hitherto limited, not so much for want of glasses truly figured according to the prescriptions of optick authors, as because that light itself is an heterogeneous mixture of differently refrangible rays ; so that were a glass so exactly figured as to collect any one sort of rays into one point, it could not collect those also into the same point, which, having the same incidence upon the same medium, are apt to suffer a different refraction.' Goethe harped on this string without cessation. ' The Newtonian doctrine,' he says, ' was really dead the moment achromatism was discovered. Gifted men our own Kliigel, for example felt this, but expressed themselves in an undecided way. On the other hand, the school which had been long accustomed to support, patch up, and glue their intellects to the views of Newton, had surgeons at hand to embalm the corpse, so that even after death, in the manner of the Egyptians, it should preside at the banquets of the natural philosophers.' In dealing with the chromatic aberration of lenses, Goethe proves himself to be less heedful than usual as an experimenter. With the clearest perception of principles, Newton had taken two pieces of cardboard, the one coloured a deep red, the other a deep blue. Around those cards he had wound fine black silk, so that the silk formed a series of separate fine dark lines upon the two coloured surfaces. He might have drawn black lines over the red and blue, but the silk lines were finer than any that he could draw. Illuminating GOETHE'S ' FARBENLEHBE.' 65 both surfaces, he placed a lens so as to cast an image of the surfaces upon a white screen. The result was, that when the dark lines were sharply defined upon the red, they were undefined upon the blue ; and that when, by moving the screen, they were ren lered distinct upon the blue, they were indistinct upon the red. A distance of an inch and a half separated the focus of red rays from the focus of blue rays, the latter being nearer to the lens than the former. Goethe appears to have attempted a repetition of this experiment ; at all events, he flatly contradicts Newton, ascribing his result not to the testimony of his bodily eyes, but to that of the prejudiced eyes of his mind. Goethe always saw the dark lines best defined upon the brighter colour. It was to him purely a matter of contrast, and not of different refrangibility. He argues caustically that Newton proves too much ; for were he correct, not only would a dioptric telescope be impossible, but when pre- sented to our naked eyes, differently-coloured objects must appear utterly confusing. Let a house, he says, be 'supposed to stand in full sunshine ; let the roof-tiles be red, the walls yellow, with blue curtains behind the open windows, while a lady with a violet dress steps out of the door. Let us look at the whole from a point in front of the house. The tiles we will suppose appear distinct, but on turning to the lady we should find both the form and the folds of her dress undefined. We must move forward to see her distinctly, and then the red tiles would appear nebulous. And so with regard to the other objects, we must move to and fro in order to see them clearly, if Newton's pretended second experiment were correct. Goethe seems to have forgotten that the human eye is not a rigid lens, and that it is able to adjust itself promptly and without difficulty to differences of distance enormously greater 66 GOETHE'S ' FARBENLEHRE.' than that due to the different refrangibility of the differently-coloured rays. Newton's theory of colours, it may be remarked, is really less a ' theory ' than a direct presentation of facts. Given the accepted definition of refraction, it is a matter of fact, and not of theoretic inference, that white light is not * homogeneal,' but composed of dif- ferently refrangible rays. The demonstration is ocular and complete. Having palpably decomposed the white light into its constituent colours, Newton recom- pounded these colours to white light. Both the analysis and the synthesis are matters of fact. The so-called ' theory of light and colours ' is in this respect very different from the corpuscular theory of light. New- ton's explanation of colour stands where it is, whether we accept the corpuscular or the undulatory theory ; and it stands because it is at bottom, not a theory, but a body of fact, to which theory must bow or disappear. Newton himself pointed out that his views of colours were entirely independent of his belief in the ' cor- poreity ' of light. After refraction-colours, Goethe turns to those pro- duced by diffraction, and, as far as the phenomena are concerned, he deals very exhaustively with the colours of thin plates. He studies the colours of Newton's rings both by reflected and transmitted light. He states the conditions under which this class of colours is produced, and illustrates the conditions by special cases. He presses together flat surfaces of glass, ob- serves the flaws in crystals and in ice, refers to the iridescences of oil on water, to those of soap-bubbles, and to the varying colours of tempered steel. He is always rich in facts. But when he comes to deal with physical theory, the poverty and confusion of his other- wise transcendent mind become conspicuous. His turbid GOETHE'S ' FARBENLEHRE.' 67 media entangle him everywhere, leading him captive and committing him to almost incredible delusions. The colours of tempered steel, he says, and kindred phenomena, may perhaps be quite conveniently deduced from the action of turbid media. Polished steel power- fully reflects light, and the colouring produced by heating may be regarded as a feeble turbidity, which, acted upon by the polished surface behind, produces a bright yellow. As the turbidity augments, this colour becomes dense, until finally it exhibits an intense ruby-red. Supposing this colour to reach its greatest proximity to darkness, the turbidity continuing to augment as before, we shall have behind the turbid medium a dark background, against which we have first violet, then dark blue, and finally light blue, thus com- pleting the cycle of the phenomena. The mind that could offer such an explanation as this must be quali- tatively different from that of the natural philosopher. The words 'quite conveniently deduced,' which I have italicised in the last paragraph, are also used by Goethe in another place. When the results of his ex- periments on prismatic colours had to be condensed into one commanding inference, lie enunciated it thus : ' Und so lassen sich die Farben bei Gelegenheit der Refraction aus der Lehre von den triiben Mitteln gar bequem ableiten.' This is the crown of his edifice, and it seems a feeble ending to so much preparation. Kingsley once suggested to Lewes that Goethe might have had a vague feeling that his conclusions were not sound, and that he felt the jealousy incident to imperfect con- viction. The ring of conscious demonstration, as it is understood by the man of science, is hardly to be found in the words, ' gar bequem ableiten.' They fall flaccid upon the ear in comparison with the mind-compelling Q.E.D. of Newton. 68 GOETHE'S ' FARBENLEHRE.' Throughout the first 350 pages of his work, wherein he develops and expounds his own theory, Goethe restrains himself with due dignity. Here and there there is a rumble of discontent against Newton, but there is no sustained ill-temper or denunciation. After, however, unfolding his own views, he comes to what he calls the * unmasking of the theory of Newton ' Here Goethe deliberately forsakes the path of calm, objective research, and delivers himself over to the guidance of his emotions. He immediately accuses Newton of misusing, as an advocate, his method of expo- sition. He goes over the propositions in Newton's optics one by one, and makes even the individual words of the propositions the objects of his criticism. He passes on to Newton's experimental proofs, invoking, as he does so, the complete attention of his readers, if they would be freed to all eternity from the slavery of a doctrine which has imposed upon the world for a hundred years. It might be thought that Goethe had given himself but little trouble to understand the theorems of Newton and the experiments on which they were based. But it would be unjust to charge the poet with any want of diligence in this respect. He repeated Newton's experi- ments, and in almost every case obtained his results. But he complained of their incompleteness and lack of logical force. What appears to us as the very perfection of Newton's art, and absolutely essential to the purity of the experiments, was regarded by Goethe as needless complication and mere torturing of the light. Ho spared no pains in making himself master of Newton's data, but he lacked the power of penetrating either their particular significance, or of estimating the force and value of experimental evidence generally. He will not, he says, shock his readers at the outset by the utterance of a paradox, but he cannot withhold GOETHE'S FARBENLEHRE; 69 the assertion that by experiment nothing can really be proved. Phenomena may be observed and classified ; experiments may be accurately executed, and made thus to represent a certain circle of human knowledge ; but deductions must be drawn by every man for himself. Opinions of things belong to the individual, and we know only too well that conviction does not depend upon insight but upon will that man can only assimilate that which is in accordance with his nature, and to which he can yield assent. In knowledge, as in action, says Goethe, prejudice decides all, and prejudice, as its name indicates, is judgment prior to investigation. It is an affirmation or a negation of what corresponds or is opposed to our own nature. It is the cheerful activity of our living being in its pursuit of truth or of false- hood, as the case may be of all, in short, with which we feel ourselves to be in harmony. There can be no doubt that Groethe, in thus philoso- phising, dipped his bucket into the well of profound self-knowledge. He was obviously stung to the quick by the neglect of the physicists. He had been the idol of the world, and accustomed as he was to the incente of praise, he felt sorely that any class of men should treat what he thought important with indifference or contempt. He had, it must be admitted, some ground for scepticism as to the rectitude of scientific judgments, seeing that his researches on morphology met at first no response, though they were afterwards lauded by scientific men. His anger against Newton incorporates itself in sharp and bitter sarcasm. Through the whole of Newton's experiments, lie says, there runs a display of pedantic accuracy ; but how the matter really stands with Newton's gift of observation, and with his experi- mental aptitudes, every man possessing eyes and senses may make himself aware. Where, it may be boldly 70 GOETHE'S ' FARBENLEHEE.' asked, can the man be found, possessing the extra- ordinary gifts of Newton, who could suffer himself to be deluded by such a hocus pocus, if he had not in the first instance wilfully deceived himself? Only those who know the strength of self-deception, and the extent to which it sometimes trenches on dishonesty, are in a condition to explain the conduct of Newton and of Newton's school. ' To support his unnatural theory,' he continues, 'Newton heaps experiment on experiment, fiction upon fiction, seeking to dazzle where he cannot convince.' It may be that Goethe is correct in affirming that the will and prejudice of the individual are all-influential. We must, however, add the qualifying words, ' as far as the individual is concerned.' For in science there exists, apart from the individual, objective truth ; and the fate of Goethe's own theory, though commended to us by so great a name, illustrates how, in the progress of humanity, the individual, if he err, is left stranded and forgotten truth, independent of the individual, being more and more grafted on to that tree of knowledge which is the property of the human race. The imagined ruin of Newton's theory did not satisfy Goethe's desire for completeness. He would explore the ground of Newton's error, and show how it was that one so highly gifted could employ his gifts for the enunciation and diffusion of such unmitigated nonsense. It was impossible to solve the riddle on purely intellectual grounds. Scientific enigmas, he says, are often only capable of ethical solution, ana with this maxim in his mind he applies himself, in the second volume of the ' Farbenlehre,' to the examination of ' Newton's Personlichkeit.' He seeks to connect him with, or rather to detach him from, the general character of the English nation that sturdy and competent race, GOETHE'S ' FARBENLEHRE/ 71 which prizes above all things the freedom of individual action. Newton was born in a storm-tossed time none indeed more pregnant in the history of the world. He was a year old when Charles I. was beheaded, and he lived to see the first George upon the throne. The shock of parties was in his ears ; changes of Ministries, Parliaments, and armies were occurring before his eyes, while the throne itself, instead of passing on by inherit- ance, was taken possession of by a stranger. What, asks Goethe, are we to think of a man who could put aside the claims, seductions, and passions incident to such a time, for the purpose of tranquilly following out his bias as an investigator ? So singular a character arrests the poet's attention. Goethe had laid down his theory of colours, he must add to it a theory of Newton. The great German is here at home, and Newton could probably no more have gone into these disquisitions regarding character, than Goethe could have developed the physical theories of Newton. He prefaces his sketch of his rival's character by reflec- tions and considerations regarding character in general. Every living thing, down to the worm that wriggles when trod upon, has a character of its own. In this sense even the weak and cowardly have characters, for they will give up the honour and fame which most men prize highest, so that they may vegetate in safety and comfort. But the word character is usually applied to the case of an individual with great qualities, who pursues his object undeviatingly, and without permit- ting either difficulty or danger to deflect him from his course. 4 Although here, as in other cases,' says Goethe,* it is the Exuberant (Ueberschwtingliche) that impresses the imagination, it must not be imagined that this attribute has anything to do with moral feeling. The maia 72 GOETHE'S ' FARBENLEHRE.' foundation of the moral law is a good will * which, in accordance with its own nature, is anxious only for the right. The main foundation of character is a strong will, without reference to right or wrong, good or bad, truth or error. It is that quality which every Party prizes in its members. A good will cherishes freedom, it has reference to the inner man and to ethical aims. The strong will belongs to Nature and has reference to the outer world to action. And inasmuch as the strong will in this world is swayed and limited by the conditions of life, it may almost be assumed as certain that it is only by accident that the exercise of a strong will and of moral rectitude find themselves in harmony with each other.' In determining Newton's position in the series of human characters, Goethe helps himself to images borrowed from the physical cohesion of matter. Thus, he says, we have strong, firm, compact, elastic, flexible, rigid or obstinate, and viscous characters. Newton's character he places under the head of rigid or obstinate, and his theory of colours Goethe pronounces to be a petrified aperpu. Newton's assertion of his theory, and his unwavering adherence to it to the end of his life, Goethe ascribes straight off to moral obliquity on Newton's part. In the heat of our discussion, he says, we have even ascribed to him a certain dishonesty. Man is subject to error, but when errors form a series, which is followed pertina- ciously, the erring individual becomes false to himself and to others. Nevertheless reason and conscience will not yield their rights. We may belie them, but they are not deceived. It is not too much to say that the more moral and rational a man is, the greater 1 I have rendered Goethe's 'gute Wille ' by good will; liie Wollcn,' which he contrasts with ' Wille,' I have rendered hyttrong will. GOETHE'S ' FAKBENLEHKE.' 73 will be his tendency to lie when he falls into error, and the vaster will be that error when he makes up his mind to persist in it. This is all intended to throw light upon Newton. When Groethe passes from Newton himself to his followers, the small amount of reserve which he exhibited when dealing with the master entirely disappears. He mocks their blunders as having not even the merit of originality. He heaps scorn on Newton's imitators. The expression of even a truth, he says, loses grace in repetition, while the repetition of a blunder is impertinent and ridiculous. To liberate oneself from an error is difficult, sometimes indeed impossible for even the strongest and most gifted minds. But to take up the error of another, and persist in it with stififnecked obstinacy, is a proof of poor qualities. The obstinacy of a man of originality when he errs may make us angry, but the stupidity of the copyist irritates and renders us miserable. And if in our strife with Newton we have sometimes passed the bounds of moderation, the whole blame is to be laid upon the school of which Newton was the head, whose incompetence is proportional to its arrogance, whose laziness is proportional to its self-sufficiency, and whose virulence and love of persecution hold each other in perfect equilibrium. There is a great deal more invective of this kind, but you will probably, and not without sadness, con- sider this enough. Invective may be a sharp weapon, but over-use blunts its edge. Even when the denuncia- tion is just and true, it is an error of art to indulge in it too long. We not only incur the risk of becoming vapid, but of actually inverting the force of reproba- tion which we seek to arouse, and of bringing it back by recoil upon ourselves. At suitable intervals, sepa- rated from each other by periods of dignified reserve, 74 GOETHE'S ' FAKBENLEHRE/ invective may become a real power of the tongue or pen. But indulged in constantly it degenerates into scolding, and then, instead of being regarded as a proof of strength, it is accepted, even in the case of a Groethe, as an evidence of weakness and lack of self-control. If it were possible to receive upon a mirror Goethe's ethical image of Newton and to reflect it back upon its author, then, as regards vehement persistence in wrong thinking, the image would accurately coincide with Groethe himself. It may be said that we can only solve the character of another by the observation of our own. This is true, but in the portraiture of character we are not at liberty to mix together subject and object as Groethe mixed himself- with Newton. So much for the purely ethical picture. On the scientific side some- thing more is to be said. I do not know whether psychologists have sufficiently taken into account that, as regards intellectual endowment, vast wealth may co- exist with extreme poverty. I do not mean to give utterance here to the truism that the field of culture is so large that the most gifted can master only a portion of it. This would be the case supposing the individual at starting to be, as regards natural capacity and poten- tiality, rounded like a sphere. Something more radical is here referred to. There are individuals who at starting are not spheres, but hemispheres ; or, at least, spheres with a segment sliced away full-orbed on one side, but flat upon the other. Such incompleteness of the mental organisation no education can repair. Now the field of science is sufficiently large, and its studies sufficiently varied, to bring to light in the same indi- vidual antitheses of endowment like that here indicated. So far as science is a work of ordering and classifi- cation, so far as it consists in the discovery of analogies and resemblances which escape the common eye of GOETHE'S ' FAKBENLEHRE.' 75 the fundamental identity which often exists among apparently diverse and unrelated things so far, in short, as it is observational, descriptive, and imagi- native, Goethe, had he chosen to make his culture ex- clusively scientific, might have been without a master, perhaps even without a rival. The instincts and ca- pacities of the poet lend themselves freely to the natural-history sciences. But when we have to deal with stringently physical and mechanical conceptions, such instincts and capacities are out of place. It was in this region of mechanical conceptions that Goethe failed. It was on this side that his sphere of endow- ment was sliced away. He probably was not the only great man who possessed a spirit thus antithetically mixed. Aristotle himself was a mighty classifier, but not a stringent physical reasoner. And had Newton attempted to produce a Faust, the poverty of his in- tellect on the poetic and dramatic side might have been rendered equally manifest. But here, if not always, Newton abstained from attempting that for which he had no gift, while the exuberance of Goethe's nature caused him to undertake a task for which he had neither ordination nor vocation, and in the attempted execution of which his deficiencies became revealed. One task among many one defeat amid a hundred triumphs. But any recognition on my part of Goethe's achievements in other realms of intellectual action would justly be regarded as impertinent. You re- member the story of the first Napoleon when the Austrian plenipotentiary, in arranging a treaty of peace, began by formally recognising the French Republic. 4 Efface that,' said the First Consul ; ' the French Re- public is like the sun ; he is blind who fails to recog- nise it.' And were I to speak of recognising Goetlr merits, my effacement would be equally well deser 6 76 GOETHE'S ' FARBENLEHEE,' ' Groethe's life,' says Carlyle, ' if we examine it, is well represented in that emblem of a solar day. Beautifully rose our summer sun, gorgeous in the red, fervid east, scattering the spectres and sickly damps, of both of which there were enough to scatter ; strong, benignant, in his noonday clearness, walking triumphant through the upper realms and now mark also how he sets I " So stirbt ein Held ; " so dies a hero ! ' Two grander illustrations of the aphorism * To err is human ' can hardly be pointed out in history than Newton and Goethe. For Newton went astray, not only as regards the question of achromatism, but also as regards vastly larger questions touching the nature of light. But though as errors they fall into the same category, the mistake of Newton was qualitatively dif- ferent from that of Goethe. Newton erred in adopting a wrong mechanical conception in his theory of light, but in doing so he never for a moment quitted the ground of strict scientific method. Goethe erred in seeking to engraft in bis ' Farbenlehre ' methods alto- gether foreign to physics or to the treatment of a purely physical theme. We frequently hear protests made against the cold mechanical mode of dealing with aesthetic phenomena employed by scientific men. The dissection by Newton of the light to which the world owes all its visible splendour seemed to Goethe a desecration. We find, even in our own clay, the endeavour of Helmholtz to arrive at the principles of harmony and discord in music resented as an intrusion of the scientific intel- lect into a region which ought to be sacred to the human heart. But all this opposition and antago- nism has for its essential cause the incompleteness those with whom it originates. The feelings and 1 s with which Newton and Goethe respectively ap- GOETHE'S ' FARBENLEHKE; 77 preached Nature were radically different, but they had an equal warrant in the constitution of man. As regards our tastes and tendencies, our pleasures and pain?, physical and mental, our action and passion, our sorrows, sympathies, and joys, we are the heirs of all the ages that preceded us ; and of the human nature thus handed down poetry is an element just as much as science. The emotions of man are older than his understanding, and the poet who brightens, purifies, and exalts these emotions may claim a position in the world at least as high and as well assured as that of the man of ?cience. They minister to different but to equally permanent needs of human nature ; and the incompleteness of which I complain consists in the endeavour on the part of either to exclude the other. There is no fear that the man of science can ever destroy the glory of the lilies of the field ; there is no hope that the poet can ever successfully contend against our right to examine, in accordance with scientific method, the agent to which the lily owes its glory. There is no necessary encroachment of the one field upon the ot!;er. Nature embraces them both, and man, when he ia complete, will exhibit as large a toleration. 1882. ATOMS, MOLECULES, AND ETHER WAVES. 1 MAN is prone to idealisation. He cannot accept as final the phenomena of the sensible world, but looks behind that world into another which rules the sensible one. From this tendency of the human mind systems ofmytbology and scientific theories have equally sprung. By the former the experiences of volition, passion, power, and design, manifested among ourselves, were transplanted, with the necessary modifications, into an unseen universe, from which the sway and potency of these magnified human qualities were exerted. * In the roar of thunder and in the violence of the storm was felt the presence of a shouter and furious strikers, and out of the rain was created an Indra or giver of rain.' It is substantially the same with science, the principal force of which is expended in endeavouring to rend the veil which separates the sensible world from an ultra-sensible one. In botli cases our materials, drawn from the world of the senses, are modified by the imagination to suit intellectual needs. The 'first beginnings ' of Lucretius were not objects of sense, but they were suggested and illustrated by objects of sense. The idea of atoms proved an early want on the part of minds in pursuit of the knowledge of Nature. It has 1 Written at Alp Lusgen for the first number of Lonyman'i Magazine. ATOMS, MOLECULES, AND ETHER WAVES. 79 never been relinquished, and in our own day it is grow- ing steadily in power and precision. The union of bodies in fixed and multiple propor- tions constitutes the basis of modern atomic theory. The same compound retains, for ever, the same elements, in an unalterable ratio. We cannot produce pure water containing one part, by weight, of hydrogen and nine of oxygen ; nor can we produce it when the ratio is one to ten ; but we can produce it from the ratio of one to eight, and from no other. So, also, when water is decomposed by the electric current, the proportion, as regards volumes, is as fixed as in the case of weights. Two volumes of hydrogen and one of oxygen invariably go to the formation of water. Number and harmony, as in the Pythagorean system, are everywhere dominant in this under-world. Following the discovery of fixed proportions we have that of multiple proportions. For the same com- pound, as above stated, the elementary factors are con- stant ; but one elementary body often unites with another so as to form different compounds. Water, for example, is an oxide of hydrogen ; but a peroxide of that substance also exists, containing exactly double the quantity of oxygen. Nitrogen also unites with oxygen in various ratios, but not in all. The union takes place, not gradually and uniformly, but by steps, a definite weight of matter being added at each step. The larger combining quantities of oxygen are thus multiples of the smaller ones. It is the same with other combinations. We remain thus far in the region of fact : why not rest there ? It might as well be asked why we do not, like our poor relations of the woods and forests, rest content with the facts of the sensible world. In virtue of our mental idiosyncrasy, we demand why bodies 80 ATOMS, MOLECULES, should combine in multiple proportions, and the out- come and answer of this question is the atomic theory. The definite weights of matter above referred to represent the weights of atoms, indivisible by any force which chemistry has hitherto brought to bear upon them. If matter were a continuum if it were not rounded off, so to say, into these discrete atomic masses the impassable breaches of continuity which the law of multiple proportions reveals could not be accounted for. These atoms are what Maxwell finely calls 'the foundation-stones of the material universe,' which, amid the wreck of composite matter, l remain unbroken and unworn.' A group of atoms drawn and held together by what chemists term affinity, is called a molecule. Tlie ultimate parts of all compound bodies are molecules. A molecule of water, for example, consists of two atoms of hydrogen, which grasp and are grasped by one atom of oxygen. When water is converted into steam, the distances between the molecules are greatly augmented, but the molecules themselves continue intact. We must not, however, picture the constituent atoms of any molecule as held so rigidly together as to render intestine motion impossible. The interlocked atoms have still liberty of vibration, which may, under certain circumstances, become so intense as to shake the molecule asunder. Most molecules probably all are wrecked by intense heat, or in other words by intense vibratory motion ; and many are wrecked by a very moderate heat of the proper quality. Indeed, a weak force which bears a suitable relation to the constitution of the molecule can, by timely savings and accumula- tions, accomplish what a strong force out of such rela- tion fails to achieve. We have here a glimpse of the world in which the AND ETHER WAVES. 81 physical philosopher for the most part resides. Science has been defined as ' organised common sense,' by whom I have forgotten; but, unless we stretch unduly the definition of common sense, I think it is hardly applica- ble to this world of molecules. I should be inclined to ascribe the creation of that world to inspiration, rather than to what is currently known as common sense. For Ihe natural-history sciences the definition may stand but hardly for the physical and mathematical sciences. The sensation of light is produced by a succession of waves which strike the retina in periodic intervals ; and such waves, impinging on the molecules of bodies, agitate their constituent atoms. These atoms are so small and, when grouped to molecules, are so tightly clasped together, that they are capable of tremors equal in rapidity to those of light and radiant heat. To a mind coming freshly to these subjects, the numbers with which scientific men here habitually deal must appear utterly fantastical; and yet, to minds trained in the logic of science, they express most sober and certain truth. The constituent atoms of molecules can vibrate to and fro millions of millions of times in a second. The waves of light and of radiant heat follow each other at similar rates through the luminiferous ether. Fur- ther, the atoms of different molecules are held together with vai-ying degrees of tightness they are tuned, as it were, to notes of different pitch. Suppose, then, light- waves, or heat-waves, to impinge upon an assemblage of such molecules, what may be expected to occur? The same as what occurs when a piano is opened and sung into. The waves of sound select the strings which respectively respond to them the strings, that is to eay, whose rates of vibration are the same as their own. Of the whole series of strings these only sound. The vibratory motion of the voice, imparted first to the 82 ATOMS, MOLECULES, air, is taken up by the strings. It may be regarded as absorbed, each string constituting itself thereby a new centre of motion. Thus also as regards the tightly-locked atoms of molecules on which waves of light or radiant heat impinge. Like the waves of sound just adverted to, the waves of ether select those atoms whose periods of vibration synchronise with their own periods of recurrence, and to such atoms they deliver up their motion. It is thus that light and radiant heat are absorbed. And here the statement, though elementary, must not be omitted, that the colours of the prismatic spec- trum, which are presented in an impure form in the rainbow, are due to different rates of atomic vibration in their source, the sun. From the extreme red to the extreme violet, between which are embraced all colours visible to the human eye, the rapidity of vibration steadily increases, the length of the waves of ether pro- duced by these vibrations diminishing in the same pro- portion. I say ' visible to the human eye,' because there may be eyes capable of receiving visual impression from waves which do not affect ours. There is a vast store of rays, or more correctly waves, beyond the red, and also beyond the violet, which are incompetent to excite our vision ; so that could the whole length of the spectrum, visible and invisible, be seen by the same eye, its length would be vastly augmented. I have spoken of molecules being wrecked by a moderate amount of heat of the proper quality : let us examine this point for a moment. There is a liquid called nitrite of amyl frequently administered to patients suffering from heart disease. The liquid is volatile, and its vapour is usually inhaled by the patient. Let a quantity of this vapour be introduced into a wide glass tube, and let a concentrated beam of solar light AND ETHER WAVES. 83 be sent through the tube along its axis. Prior to the entry of the beam, the vapour is as invisible as the purest air. When the light enters, a bright cloud is immediately precipitated on the beam. This is entirely due to the waves of light, which wreck the nitrite of amyl molecules, the products of decomposition forming innumerable liquid particles, which constitute the cloud. Many other gases and vapours are acted upon in a similar manner. Now the waves that produce this de- composition are by no means the most powerful of those emitted by the sun. It is, for example, possible to gather up the ultra-red waves into a concentrated beam, and to send it through the vapour, like a beam of light. But though possessing vastly greater energy than the light waves, they fail to produce decomposition. Hence the justification of the statement already made, that a suitable relation must subsist between the molecules and the waves of ether to render the latter effectual. A very impressive illustration of the decomposing power of the waves of light is here purposely chosen ; but the processes of photography illustrate the same prin- ciple. The photographer, without fear, illuminates his developing- room with light transmitted through red or yellow glass; but he dares not use blue glass, for blue light would decompose his chemicals. And yet the waves of red light, measured by the amount of energy which they carry, are immensely more powerful than the waves of blue. The blue rays are usually called che- mical rays a misleading term ; for, as Draper and others have taught us, the rays that produce the grandest chemical effects in Nature, by decomposing the carbonic acid and water which form the nutriment of plants, are not the blue ones. In regard, however, to the salts of silver, and many other compounds, the blue rays are the most effectual. How is it, then, that 84 ATOMS, MOLECULES, weak waves can produce effects which strong waves are incompetent to produce ? This is a feature character- istic of periodic motion. In the experiment of singing into an open piano already referred to, it is the accord subsisting between the vibrations of the voice and those of the string that causes the latter to sound. Were this accord absent, the intensity of the voice might be quin- tupled, without producing any response. But when voice and string are identical in pitch, the successive impulses add themselves together, and this addition renders them in the aggregate powerful, though in- dividually they may be weak. In some such fashion the periodic strokes of the smaller ether waves accumu- late, till the atoms on which their timed impulses im- pinge are jerked asunder, and what we call chemical decomposition ensues. Savart was the first to show the influence of musical Bounds upon liquid jets, and I have now to describe an experiment belonging to this class, which bears upon the present question. From a screw-tap in my little Alpine kitchen I permitted, an hour ago, a vein of water to descend into a trough, so arranging the flow that the jet was steady and continuous from top to bottom. A slight diminution of the orifice caused the continuous portion of the vein to shorten, the part further down resolving itself into drops. In my experiment how- ever the vein, before it broke, was intersected by the bottom of the trough. Shouting near the descending jet produced no sensible effect upon it. The higher notes of the voice, however powerful, were also ineffec- tual. But when the voice was lowered to about 130 vibrations a second, the feeblest utterance of this note sufficed to shorten, by one-half, the continuous portion of the jet. The responsive drops ran along the vein pattered against the trough, and scattered a copious AND ETHER WAVES. 85 spray round their place of impact. When the note ceased, the continuity and steadiness of the vein were immediately restored. The formation of the drops was here f >eriodic ; and when the vibrations of the note accurately synchronised with the periods of the drops, the waves of sound aided what the illustrious Plateau proved to be the natural tendency of the liquid cylinder to resolve itself into spherules, and virtually decom- posed the vein. I have stated, without proof, that where absorption occurs the motion of the ether-waves is taken up by the constituent atoms of molecules. It is conceivable that the ether waves, in passing through an assemblage of molecules, might deliver up their motion to each molecule as a whole, leaving the relative positions of the constituent atoms unchanged. But the long series of reactions represented by the deportment of nitrite of amyl vapour does not favour this conception ; for, were the atoms animated solely by a common motion, the molecules would not be decomposed. The fact of de- composition, then, goes to prove the atoms to be the seat of the absorption. They, in great part, take up the energy of the ether waves, whereby their union is Fevered, and the building-materials of the molecules are scattered abroad. Molecules differ in stability ; some of them, though hit by waves of considerable force, and taking up the motions of these waves, nevertheless hold their own with a tenacity which defies decomposition. And here, in passing, I may say that it would give me extreme pleasure to be able to point to my researches in con- firmation of the solar theory recently enunciated by my friend the President of the British Association. But though the experiments which I have made on the de- composition of vapours by light might be numbered bj 86 ATOMS, MOLECULES, the thousand, I have, to my regret, encountered no fact which proves that free aqueous vapour is decomposed by the solar rays, or that the sun is nourished by the re- combination of gases, in the severance of which it had previously sacrificed its heat. The memorable investigations of Leslie and Rum- ford, and the subsequent classical researches of Melloni and Knoblauch, dealt, in the main, with the properties of radiant heat ; while, in my investigations, radiant heat, instead of being regarded as an end, was employed as a means of exploring molecular condition. On this score little could be said until the gaseous form of matter was brought under the dominion of experiment. This was first effected in 1859, when it was proved that gases and vapours, notwithstanding the open door which the distances between their molecules might be supposed to offer to the heat waves, were, in many cases, able effec- tually to bar their passage. It was then proved that while the elementary gases and their mixtures, including among the latter the earth's atmosphere, were almost as pervious as a vacuum to ordinary radiant heat, the compound gases were one and all absorbers, some of them indeed taking up with intense avidity the motion of the ether waves. A single illustration will here suffice. Let a mix- ture of hydrogen and nitrogen in the proportion of three to fourteen by weight be enclosed in a space through which are passing the heat-rays from an ordinary stove. The gaseous mixture offers no measurable impediment to the rays of heat. Let the hydrogen and nitrogen now unite to form the compound ammonia. A magical change instantly occurs. The number of atoms present remains unchanged. The transparency of the com- pound is quite equal to that of the mixture prior to AND ETHER WAVES. 87 combination. No change is perceptible to the eye, but the keen vision of experiment soon detects the fact that the perfectly transparent and highly attenuated ammonia resembles pitch or lampblack in its behaviour to the rays of obscure heat. There is probably boldness, if not rashness, in the attempt to make these ultra-sensible actions generally intelligible, and I may have already transgressed the limits beyond which the writer of a familiar article cannot profitably go. There may, however, be a rem- nant of readers willing to accompany me, and for their sakes I proceed. A hundred compounds might be named which, like the ammonia, are transparent to light but more or less opaque often, indeed, intensely opaque to the rays of heat from obscure sources. Now the difference between these latter rays and the light- rays is purely a difference of period of vibration. The vibrations in the case of light are more rapid, and the ether waves which they produce are shorter, than in the case of obscure heat. Why then should the ultra- red waves be intercepted by bodies like ammonia, while the more rapidly recurrent waves of the whole visible spectrum are allowed free transmission ? The answer I hold to be that, by the act of chemical combination, the vibrations of the constituent atoms of the mole- cules are rendered so sluggish as to synchronise with the motions of the longer waves. They resemble loaded piano-strings, or slowly descending water-jets, requiring notes of low pitch to set them in motion. The influence of synchronism between the ' radiant ' and the ' absorbent ' is well shown by the behaviour of carbonic acid gas. To the complex emission from our heated stove, carbonic acid would be one of the most transparent of gases. For such waves olefiant gas, for ex- ample, would vastly transcend it in absorbing power 68 ATOMS, MOLECULES, But when we select a radiant with whose waves the atoms of carbonic acid are in accord, the case is entirely altered. Such a radiant is found in a carbonic oxide flame, where the radiating body is really hot carbonic acid. To this special radiation carbonic acid is the most opaque of gases. And here we find ourselves face to face with a question of great delicacy and importance. Both as a radiator and as an absorber carbonic acid is, in general, a feeble gas. It is beaten in this respect by chloride of methyl, ethylene, ammonia, sulphurous acid, nitrous oxide, and marsh gas. Compared with some of these gases, its behaviour in fact approaches that of ele- mentary bodies. May it not help to explain their neutrality ? The doctrine is now very generally accepted that atoms of the same kind may, like atoms of different kinds, group themselves to molecules. Affinity exists between hydrogen and hydrogen, and between chlorine and chlorine, as well as between hydrogen and chlorine. \Ve have thus homogeneous molecules as well as hetero- geneous molecules, and the neutrality so strikingly ex~ hibited by the elements may be due to a quality of which carbonic acid furnishes a partial illustration. The paired atoms of the elementary molecules may be so out of accord with the periods of the ultra-red waves the vibrating periods of these atoms may, for ex- ample, be so rapid as to disqualify them both from emitting those waves, and from accepting their energy. This would practically destroy their power, both as radiators and absorbers. I have reason to know that by a distinguished authority this hypothesis has for some time been entertained. We must, however, refresh ourselves by occasional contact with the solid ground of experiment, and an in- teresting problem now lies before us awaiting experi- AND ETHER WAVES. 89 mental solution. Suppose 200 men to be scattered equably throughout the length of Pall Mall. By timely swerving now and then a runner from St. James's Palace to the Athenseum Club might be able to get through such a crowd without much hindrance. But supposing the men to close up so as to form a dense file crossing Pall Mall from north to south: such a barrier might seriously impede, or entirely stop, the runner. Instead of a crowd of men, let us imagine a column of molecules under small pressure, thus resem- bling the sparsely-distributed crowd. Let us suppose the column to shorten, without change in the quantity of matter, until the molecules are so squeezed together as to resemble the closed file across Pall Mall. During these changes of density, would the action of the mole- cules upon a beam of heat passing among them re- semble the action of the crowd upon the runner ? We must answer this question by direct experiment. To form our molecular crowd we place, in the first in- stance, a gas or vapour in a tube 38 inches long, the ends of which are closed with circular windows, air- tight, but formed of a substance which offers little or no obstruction to the calorific waves. Calling the measured value of a heat-beam passing through this tube, when empty, 100, we carefully determine the pro- portionate part of this total absorbed when the molecules are in the tube. We then gather precisely the same number of molecules into a column 10*8 inches long, the one column being thus three and a half times the other. In this case also we determine the quantity of radiant heat absorbed. By the depression of a barometric column, we can easily and exactly measure out the pro- per quantities of the gaseous body. It is obvious that 1 mercury inch of vapour, in the long tube, would represent precisely the same amount of matter or in 90 ATOMS, MOLECULES, other words the same number of molecules as 3^ inches in the short one ; while 2 inches of vapour in the long tube would be equivalent to 7 inches in the short one. The experiments have been made with the vapours of two very volatile liquids, namely, sulphuric ether and hydride of amyl. The sources of radiant heat were, in some cases, an incandescent lime cylinder, and in others a spiral of platinum wire heated to bright red- ness by an electric current. One or two of the measure- ments will suffice for the purposes of illustration. First, then, as regards the lime-light : For 1 inch of pressure in the long tube, the absorption was 18'4 per cent, of the total beam ; while for 3-5 inches of pressure in the short tube, the absorption was 18'8 per cent., or almost exactly the same as the former. For 2 inches pressure, moreover, in the long tube, the absorption was 25-7 per cent. ; while for 7 inches, in the short tube, it was 25 - 6 per cent, of the total beam. Thus closely do the ab- sorptions in the two cases run together thus empha- tically do the molecules assert their individuality. As long as their number is unaltered, their action on radiant heat is unchanged. Passing from the lime- light to the incandescent spiral, the absorptions of the smaller equivalent quantities in the two tubes were 23 - 5 and 23-4 per cent. ; while the absorptions of the larger equivalent quantities were 32-1 and 32*6 per cent, respectively. This constancy of absorption, when the density of a gas or vapour is varied, I have called ' the conservation of molecular action.' But it may be urged that the change of density in these experiments has not been carried far enough to justify the enunciation of a law of molecular physics. The condensation into less than one-third of the space does not, it may be said, quite represent the close file AND ETHER WAVES. 91 of men across Pall Mall. Let us therefore push matters tu extremes, and continue the condensation till the vapour has been squeezed into a liquid. To the pure change of density we shall then have added the change in the state of aggregation. The experiments here are more easily described than executed ; nevertheless, by sufficient training, scrupulous accuracy, and minute attention to details, success may be ensured. Knowing the respective specific gravities, it is easy, by calcula- tion, to determine the condensation requisite to re- duce a column of vapour of definite density and length to a layer of liquid of de6nite thickness. Let the vapour, for example, be that of sulphuric ether, and let it be introduced into our 38-inch tube till a pressure of 7'2 inches of mercury is obtained. Or let it be hydride of amyl of the same length, at a pressure of 6-6 inches. Supposing the column to shorten, the vapour would become proportionally denser, and would, in each case, end in the production of a layer of liquid exactly 1 millimeter in thickness. 1 Conversely, a layer of liquid ether, or of hydride of amyl. of this thickness, were its molecules freed from the thrall of cohesion, would form a column of vapour 38 inches long, at a pressure of 7'2 inches in the one case, and of 6'6 inches in the other. In passing through the liquid layer, a beam of heat encounters the same number of molecules as in passing through the vapour layer ; and our prob- lem is to decide, by experiment, whether, in both cases, the molecule is not the dominant factor, or whether its power is augumented, diminished, or otherwise over- ridden by the state of aggregation. Using the sources of heat before-mentioned, and employing diathermanous lenses, or silvered mirrors, to render the rays from those sources parallel, the absorp- 1 The millimeter is ^th of an inch. 7 92 ATOMS, MOLECULES, tion of radiant heat was determined, first for the liquid layer, and then for its equivalent vaporous layer. As before, a representative experiment or two will suffice for illustration. When the substance was sulphuric ether, and the soilrce of radiant heat an incandescent platinum spiral, the absorption by the column of vapour was found to be 6 6 ? per cent, of the total beam. The absorption of the equivalent liquid layer was next de- termined, and found to be 67*2 per cent. Liquid and vapour, therefore, differed from each other only 0*5 per cent. : In other words, they were practically identical in their action. The radiation from the lime-light has a greater power of penetration through transparent substances than that from the spiral. In the emission from both of these sources we have a mixture of obscure and luminous rays ; but the ratio of the latter to the former, in the lime-light, is greater than in the spiral ; and, as the very meaning of transparency is perviousness to the luminous rays, the emission in which these rays are predominant must pass most freely through trans- parent substances. Increased transmission implies dimi- nished absorption ; and, accordingly, the respective ab- sorptions of ether vapour and liquid ether when the lime-light was used, instead of being 66*7 and 67'2 per cent., were found to be Vapour . . . 33'3 per cent. Liquid .... 33'3 no difference whatever being observed between the two states of aggregation. The same was found true of hydride of amyl. This constancy and continuity of the action exerted on the waves of heat when the state of aggregation is changed I have called 'the thermal continuity of liquids and vapours.' It is, I think, the strongest AND ETHER WAVES. 93 illustration hitherto adduced of the conservation of molecular action. Thus, by new methods of search, we reach a result which was long ?go enunciated on other grounds. Water is well known to be one of the most opaque of liquids to the waves of obscure ht-at. But if the re- lation of liquids to their vapours be that here shadowed forth if in both cases the molecule asserts itself to be the dominant factor then the dispersion of the water of our seas and rivers as invisible aqueous vapour in our atmosphere, does not annul the action of the molecules on solar and terrestrial heat. But as aqueous vapour is transparent which, as before explained, means pervious to the luminous rays and as the emission from the sun abounds in such rays while from the earth's emission they are wholly absent, the vapour screen offers a far greater hindrance to the outflow of heat from the earth towards space than to the inflow from the sun towards the earth. The elevation of our planet's temperature is therefore a direct consequence of the existence of aqueous vapour in our air. Were that garment re- moved, terrestrial life would probably perish through the consequent refrigeration. I have thus endeavoured to give some account of recent incursions into that ultra-sensible world the world of the * scientific imagination ' mentioned at the outset of this paper. Invited by my publishers, with whom I have so long worked in harmony, to send some contribution to the first number of their new Magazine, I could not refuse them this proof of my good- will. NOTE. The researches glanced at in the foregoing brief article have been published in extenso in the 'Philosophical Transactions.' I would invite to them and others, in their correct historical sequence, the attention of my friend Professor Von Hofmann. 1883. COUNT RUMFORD* ON a bright calm day in the autumn of 1872 that portion of the year called, I believe, in America the Indian summer I made a pilgrimage to the modest birthplace of Count Rumford. My guide on the occasion was Dr. George Ellis of Boston, and a more competent guide I could not possibly have had. To Dr. Ellis the American Academy of Arts and Sciences had committed the task of writing a life of Rumford, and this labour of love had been accomplished in 1871, a year prior to my visit to the United States. In regard to Rumford's personal life, Dr. Ellis's elaborate volume constitutes, if I may so speak, the quarry out of which the building- materials of these lectures are drawn. The life of such a man, however, cannot be duly taken in without reference to his work, and the publication by the American Academy of Sciences of four large volumes of Rumford's essays renders the task of dealing with his labours lighter than it would have been had his writings been suffered to remain scattered in the magazines, journals, and transactions of learned societies in which they originally appeared. The name of Count Rumford was Benjamin Thomp- eon. For thirty years he was the contemporary of 1 From a short course of lectures delivered in the Iloyal Institution COUNT RUMFORD. 95 another Benjamin, who reached a level of fame as high as his own. Benjamin Franklin and Benjamin Thompson were born within twelve miles of each other, and for six of the thirty years just referred to the one lived in England and the other in France. Still, there is nothing to show that they ever saw each other, or were in any way acquainted with each other, or, indeed, felt the least interest in each other. As regards posthumous fame, Eumford has fared worse than Franklin. For ten, or perhaps a hundred, people in this country who know something of the career of the one, hardly a unit is to be found acquainted with the career of the other. Among scientific men, however, the figure of Rumford presents itself with singular impressiveness at the present day a result mainly due to the establishment of the grand scientific generalisation known as the Mechanical Theory of Heat. Boyle, and Hooke, and Locke, and Leibnitz, had already distinctly ranged themselves on the side of this theory. But by experi- ments conducted on a scale unexampled at the time, and by reasonings, founded on these experiments, of singular force and penetration, Rumford has made him- self a conspicuous landmark in the history of the theory. His inference from his experiments was that heat is a form of motion. The town of Woburn, connected in my memory with a cultivated companion, with genial sunshine and the bright colouring of American trees, is nine miles distant from the city of Boston. In North Woburn, a little way off, on March 26, 1753, Rumford was born. He came of people who had to labour for their livelihood, who tilled their own fields, cut their own timber and fuel, worked at their varied trades, and thus maintained the in- dependence of New England yeomen. Thompson's 96 COUNT RUMFORD. father died when he was two years old. His mothei married again, and had children by her second husband ; but the affection between her and her firstborn remained strong and unbroken. The arrangements made for the maintenance of mother and son throw some light upon their position. She was to have the use of one-half of a garden ; the privilege of land to raise beans for sauce; to receive within a specified time 80 ' weight' of beef, 8 bushels of rye, 2 bushels of malt, and 2 barrels of cider. Finally, she had the right of gathering apples to bake, and a further allowance of three bushels of apples every year. The fatherless boy had been placed under the care of a guardian, from whom his stepfather, Josiah Pierce, received a weekly allowance of two shillings and five- pence for the child's maintenance. Young Thompson received his first education from Mr. John Fowle, a graduate of Harvard College, described by Dr. Ellis as * an accomplished and faithful man.' He also went to a school at Bj'field, kept by a relation of his own. At the age of eleven he was placed for a time under the tuition of a Mr. Hill, ' an able teacher in Medford,' ad- joining Woburn. The lad's mind was ever active, and his invention incessantly exercised, but for the most part on subjects apart from his daily work. In relation to that work he came to be regarded as ' indolent, flighty, and unpromising.' His guardian at length thinking it advisable to change his vocation, apprenticed him in October 1766 to Mr. John Appleton, of Salem, an importer of British goods. Here, however, instead of wooing customers to his master's counter, he occupied himself with tools and implements hidden beneath it. He is reported to have been a skilful musician, passion- ately fond of music of every kind ; and during his stay with Mr. Appleton, whenever he could do so without COUNT EUMFOED. 97 being heard, he solaced his leisure with performances on the violin. By the Rev. Thomas Barnard, minister of Salem, and his son, young Thompson was taught algebra, geometry, and astronomy. By self-practice he became an able and accurate draughtsman. He did not escape that last infirmity of ingenious minds the desire to construct a perpetual motion. He experimented with fireworks, and was once seriously burnt by the unexpected ignition of his materials. His inquisitiveness is illus- trated by the questions put to his friend Mr. Baldwin in 1769. He wishes to be told the direction pursued by the rays of light under certain conditions ; he desires to know the cause of the change of colour which fire produces in clay. ' Please,' he adds, * to give the nature, essence, beginning of existence, and rise of the wind in general, with the whole theory thereof, so as to be able to answer all questions relative thereto.' One might suppose him to be preparing for a competitive examina- tion. He grew expert in drawing caricatures, a spirited group of which has been reproduced by Dr. Ellis. It is called a Council of State, and embraces a jackass with twelve human heads. These sketches were found in a mutilated scrap-book, which also contained a kind of journal of bis proceedings in 1769. He mentions a French class which he attended in the evenings, records the purchase of a certain measure of black cloth, states his debt to his uncle, Hiram Thompson, for part of the rent of a pew. The liabilities thus incurred he met by cutting and carting firewood. Mixed with entries such as these are * directions for the backsword,' in which the postures of the combatants are defined and illustrated by sketches. The scrap-book also contained an account of the expense Howards getting an electrical machine.' 98 COUNT RUMFORD. Soon afterwards he began the study of medicine undei Dr. John Hay, of "Woburn. Thompson kept a strict account of his debts to Dr. Hay, crediting him with such things as leather gloves,and Mrs. Hay with knitting him a pair of stockings. These items he tacks on to the more serious cost of his board, from December 1770 to June 1772, at forty shillings, old currency, per week, amounting to 1 561. The specie payments of Thompson were infinitesimal, eight of them amounting in the aggregate to '21. His further forms of payment illustrate the habits of the community in which he dwelt. Want of money caused them to fall back upon barter. He debited Dr. Hay with the follow- ing items, the value of which no doubt had been pre- viously agreed upon between them : * To ivory for smoke machine ; parcels of butter, coffee, sugar, and tea ; parcels of various drugs, camphor, gum benzoine, arsenic, calomel, and rhubarb ; one-half of white sheep- skin leather ; brass wire ; white oak timber ; to sundry lots of wood ; to other lots delivered while I was at Wilmington, and left by me when I was at Wilmington the last time ; to a blue Huzza cloak, bought of Zebe- diah Wyman, and paid for by fifteen and a half cords of wood ; a pair of knee buckles ; a chirurgical knife ; to a cittern, and to the time I have been absent from your house, nineteen weeks at forty shillings ; and for the time my mother washed for me.' To help him, moreover, to eke out the funds necessary for the pro- secution of his studies, Thompson tried his hand from time to time at school-teaching. At this early age for he was not more than seven- teen he had learnt the importance of order in the dis- tribution of his time. The four-and-twenty hours of a single day are thus spaced out : ' From eleven to six, sleep. Get up at six o'clock and wash my hands and COUNT RUMFORD. 99 face. From six to eight, exercise one-half, and study one-half. From eight to ten, breakfast, attend prayers, &c. From ten to twelve, study all the time. From twelve to one, dine, &c. From one to four, study con- stantly. From four to five, relieve my mind by some di- version or exercise. From five till bedtime, follow what my inclination leads me to ; whether it be to go abroad, or stay at home and read either Anatomy, Physic, or Chemistry, or any other book I want to peruse.' In 1771 he managed, by walking daily from Woburn to Cambridge and back, a distance of some sixteen miles, to attend the lectures on natural philosophy delivered by Professor Winthrop in Harvard College. This privilege was secured to him by his friend Mr. Baldwin. Thompson had taught school for a short time at Wilmington, and afterwards for six weeks and three days at Bradford, where his repute rose so high that he received a call to Concord, the capital of New Hampshire. The Indian name of Concord was Pena- cook. In 1733 it had been incorporated as a town in Essex County, Massachusetts. Some of the early settlers had come from the English Essex ; and, as regards pronunciation, they carried with them the name of the English Essex town, Romford, of brewery cele- brity. They, however, changed the first o into u, call- ing the American town Rumford. Strife had occurred as to the county or State to which Rumford belonged. But the matter was amicably settled at last ; and to denote the subsequent harmony, the name was changed from Rumford to Concord. 1 In later years, when hon- 1 Not to be confounded with the Concord rendered famous as the dwelling-place of Emerson. In connection with the foregoing subject I have been favoured with the following interesting letter : ' Addison Lodge, Barnes, S.W. : August 19. L>LA.> 6IU, I venture to proffer a remark upon a detail in your 100 COUNT RUMFORD. ours fell thick upon him, Rumford was made a Count of the Holy Roman Empire. He chose for his title Count Rumford, in memory of his early association with Concord. 4 When Benjamin Thompson went to Concord as a teacher, he was in the glory of his youth, not having yet reached manhood. His friend Baldwin describes him as of a fine manly make and figure, nearly six feet in height, of handsome features, bright blue eyes, and dark auburn hair. He had the manners and polish of a gentleman, with fascinating ways and an ability to interesting paper upon Count Rumford. My apology for so doing is that I am a Romford man, and that I think you may care for the mere crumb of information I possess bearing upon the spelling and pronunciation of the name of my native place. ' Romford is always pronounced R?/mford by Essex folk. When I was a boy it was spelled almost indifferently, Romford and Rum- ford. I remember that the post-mark in my school-days (some fortj years ago) was Ru-mford. Norden's map of Essex (1599) has Rum- forde ; and on Bowen's map (1 775) the spelling is the same Rum- ford. The registers in the vestry book, from 1665 until some fifty years ago, give Rumford. So that I think it safe to say that the traditional spelling and pronunciation with the Essex settlers at Concord must have been Rumford. I must, however, add but I fear I am hardly justified in troubling you with so long a note that the o occurs in two Latin entries in the Register : ' " 1664, Baptizata fuit Anna Baylie filia Hugonis Cissor, Romford." ' And in the same year there is an entry of a burial with " Rom- fordiae." I believe it was the Latinising of Rumford that modified the vowel, the alteration being prompted by the mistaken notion that the etymology of the place was Roman-ford. That the Rum is Eng- lish ( = broad) is, 1 think, hardly open to question. The nearest ford town is llford, with which the roomy ford contrasts. Of late the sluggish little river has come to be called the river Rom. This is quite a novel " notion," and is quite local. ' Thanking you for the pleasure and profit I have derived from reading your article, ' I remain, dear Sir, ' Yours very faithfully, *HENKY ATTWEU* I'rofessor Tyndall, F.R.S., &c., &c., &c.' COUNT BUMFORD. 101 make himself agreeable.' 1 Thus writes his biographer. In Concord, at the time of Thompson's arrival, dwelt the widow of Colonel Rolfe with her infant son. Her husband had died in December 1771, leaving a large estate behind him. Thompson was indebted to Mrs. Eolfe's father, the Rev. Timothy Walker, minister of Concord, for counsel, and to her brother for civility and hospitality. The widow and the teacher met, and their meeting was a prelude to their marriage. Rum- ford, somewhat ungallantly, told his friend Pictet in after-years that she married him rather than he her. She was obviously a woman of decision. As soon as they were engaged an old curricle, left by her father, was fished up, and, therein mounted, she carried Thompson to Boston, and committed him to the care of the tailor and hairdresser. This journey involved a drive of sixty miles. On the return journey, it is said, they called at the house of Thompson's mother, who when she saw him exclaimed, ' Why, Ben, my son, how could you go and lay out all your winter's earnings in finery?' Thompson was nineteen when he married, his wife being thirty-three. In 1772 he became acquainted with Governor Went- wortli, then resident at Portsmouth. On the 13th of November there was a grand military review at Dover, New Hampshire, ten miles from Portsmouth, at which Thompson was present. On two critical occasions in the life of this extraordinary man his appearance on horseback apparently determined his career. As he rode among the soldiers at Dover, his figure attracted the attention of the governor, and on the day following he was the great man's guest. So impressed was Wentworth with his conversation that he at once made up his mind to attach Thompson to the public service. 1 Ellis, p. 43. PTAT* TACH . .,NTA BARBARA. CAUlC*NI 102 COUNT KtTMFORD. To secure this wise end he adopted unwise means. * A vacancy having occurred in a majorship in the Second Provincial JRegiment of New Hampshire, Governor Wentworth at once commissioned Thompson to fill it.' Jealousy and enmity naturally followed the appoint- ment of a man without name or fame in the army, over the heads of veterans with infinitely stronger claims. He rapidly became a favourite with the governor, and on his proposing, soon after his appointment, to make a survey of the White Mountains, Wentworth not only fell in with the idea, but promised, if his public duties permitted, to take part in the survey himself. It will be remembered that at this time Thompson was not quite twenty years old. For a moment, in 1773, he appears in the character of a farmer, and invokes the aid of a friend to procure for him supplies of grass and garden seeds from Eng- land. But amid preoccupations of this kind his scientific bias emerges. After a brief reference to the seed procured for him by his friend Baldwin, he pro- poses to the latter the following question : * A certain cistern has three brass cocks, one of which will empty it in fifteen minutes, one in thirty minutes, and the other in sixty minutes. Qu. How long would it take to empty the cistern if all three cocks were to be opened at once ? If you are fond of a correspondence of this kind, and will favour me with an easy question, arithmetical or algebraical, I will endeavour to give as good an account of it as possible. If you find out an answer to the above immediately, I hope you will not take as an affront my proposing anything which you may think so easy, for I must confess I scarce ever met with any little notion that puzzled me so much in my life.' In 1774 the ferment of discontent with the legisla- COUNT RUMFORD. 103 tion of the mother country had spread throughout the colony. Clubs and committees were formed which often compelled men to take sides before the requisite data for forming a clear judgment had been obtained. ' Our candour,' says Dr. Ellis, * must persuade us to allow that there were reasons, or at least prejudices and apprehensions, which might lead honest and right- hearted men, lovers and friends of their birthland, to oppose the rising spirit of independence, as inflamed by demagogues, and as foreboding discomfiture and mis- chief.' Thompson became ' suspect,' though no record of any unfriendly or unpatriotic act or speech on his part is to be found. He was known to be on friendly terms with Governor Wentworth ; but the governor, when he gave Thompson his commission, was highly popular in the province. Prior to Wentworth's acces- sion to office he ' had strongly opposed every measure of Great Britain which was regarded as encroaching upon our liberties.' He thought himself, nevertheless, in duty bound to stand by the royal authority when it was openly defied. This rendered him obnoxious. Thompson was a man of refractory temper, and the circumstances of the time were only too well calculated to bring that temper out. < There was something,' says Dr. Ellis, ' exceedingly humiliating and degrading to a man of an independent and self-respecting spirit in the conditions imposed at times by the " Sons of Liberty," in the process of cleansing oneself from the taint of Toryism. The Committees of Correspondence and of Safety, whose services stand glorified to us through their most efficient agency in a successful struggle, delegated their authority to every witness or agent who might be a self-constituted guardian of patriotic interests, or a spy, or an eavesdropper, to catch reports of suspected persons.' Human nature 104 COUNT RUMFORD. is everywhere tne same, and to protect a cherished cause these * Sons of Liberty * sometimes adopted the tactics of the Papal Inquisition. Public feeling grew day by day more exasperated against Thompson, and in the summer of 1774 he was summoned before a committee to answer to the charge of being unfriendly to the cause of liberty. * He denied the charge, and challenged proof. The evidence, if any such was offered and no trace of testimony, or even of imputation of that kind is on record was not of a sort to warrant any proceeding against him; and he was dis- charged.' This, however, gave him but little relief, and extra-judicial plots were formed against him. The Concord mob resolved to take the matter into their own hands. One day they collected round his house, and with hoots and yells demanded that Thompson should be delivered up to them. Having got wind of the matter he escaped in time. In a letter addressed to his father-in-law at this time from Charlestowu, near Boston, he gives his reasons for quitting home. ' To have tarried at Concord and have stood another trial at the bar of the populace would doubtless have been attended with unhappy consequences, as my innocence would have stood me in no stead against the prejudices of an enraged, infatuated multitude and much less against the determined villainy of my inveterate enemies, who strive to raise their popularity on the ruins of my character.' He returned to his mother's house in Woburn, where he was joined by his wife and child. While they were with him, shots were exchanged and blood was shed at Concord (Emerson's Concord) and Lexington. Thompson was at length arrested, and confined in Wo- burn. A ' Committee of Correspondence ' was formed to inquire into his conduct. They invited everyone who COUNT RUMFORD. 105 could give evidence in the affair to appear at the meeting- house on May 18. The committee met, but finding nothing against the accused, they adjourned the meeting. He then addressed a petition to the Committee of Safety for the colony of Massachusetts Bay, in which he begged for a full and searching trial, relying on an acquittal commensurate with the thoroughness of the examination. The petition was not attended to. On May 29, 1775, he was examined at Woburn, where he conducted his own defence. He was acquitted by the committee, who recommended him to the ' protection of all good people in this and the neighbouring provinces.' The com- mittee, however, refused to make this acquittal a public one, lest, it was alleged, it should offend those who were opposed to Thompson. Despair and disgust took possession of him more and more. In a long letter addressed to his father-in-law from Woburn, he defends his entire course of conduct. His principal offence was probably negative ; for silence at the time was deemed tantamount to antagonism. During his brief period of farming he had working for him some deserters from the British army in Boston. These he persuaded to go back, and this was urged as a crime against him. He defended himself with spirit, declaring after he had explained his motives that if his action were a crime, he gloried in being a criminal. He made up his mind to quit the country, expressing the devout wish l that the happy time may soon come when I may return to my family in peace and safety, and when every individual in America may sit down under his own vine and under his own fig-tree, and have none to make him afraid.' On this letter, and on the circumstances of the time, Dr. Ellis makes the following wise and pertinent re- maiks: 'Major Thompson was not the only person in 106 COUNT KUMFORJJ. those troubled times that had occasion to charge upon those espousing the championship of public liberty a tyrannical treatment of individuals who did not accord with their schemes or views. Probably in our late war of rebellion his case was paralleled by those of hundreds in both sections of our country, who, with halting and divided minds or unsatisfied judgments, were arrested in the process of decision by treatment from others which put them under the lead of passion. The choice of a great many Royalists in our revolution would have been wiser and more satisfactory to themselves, had they been allowed to make it deliberately.' On October 13, 1775, Thompson quitted Wobuvn, reached the shore of Narraganset Bay, and went on board a British frigate. In this vessel he was conveyed to Boston, where he re- mained until the town was evacuated by the British troops. The news of this catastrophe he carried to England. Henceforward, till the close of the war, he was on the English side. As a matter of course, he was proscribed by his countrymen, and his property confiscated. Thompson was not only a man of great capacity, but, in early days, of a social pliancy and teachableness which enabled him with extreme rapidity to learn the manners and fall into the ways of great people. On the English side the War of Independence was begun, continued, and ended, in ignorance. Even now we can hardly read the pages of * The Virginians ' which refer to these times with out exasperation. Blunder followed blunder, and defeat followed defeat, until the knowledge which ought to have been ready at the outset came too late. Thompson for a time was the vehicle of such be- lated knowledge. He was immediately attached to the Colonial Office, then ruled over by Lord George Ger- main. Cuvier, in his ' Eloge,' thus describes his first interview with that Minister : * On this occasion, by the COUNT RUMFORD. 107 clearness of his details and the gracefulness of his man- ners, he insinuated himself so far into the graces of Lord George Germain that he took him into his em- ployment.' With Lord George he frequently bieak- fasted, dined, and supped, and was occasionally his guest in the country. But besides giving information useful to his chiefs, he occupied himself with other matters. He was a born experimentalist, handy, in- genious, full of devices to meet practical needs. He turned his attention to improvements in military matters; 'advised and procured the adoption of bayonets for the fusees of the Horse Guards, to be used in fight- ing on foot.' He had previously been engaged with experiments on gunpowder, which he now resumed. The results of these experiments he communicated to Sir Joseph Banks, then President of the Eoyal Society, with whom he soon became intimate. In 1779 he was elected a Fellow of the Royal Society. When the war had become hopeless, many of the exiles who had been true to the Royalist cause came to England, where Thompson's official position imposed on him the duty of assuaging their miseries and adjusting their claims. In this connection, the testimony of Dr. Ellis regarding him is that, ' so far as the relations be- tween these refugees and Mr. Thompson can be traced, I find no evidence that he failed to do in any case what duty and friendliness required of him.' Still he did not entirely escape the censure of his outlawed fellow- countrymen. One of them in particular had been a judge in Salem when Thompson was a shopboy in Appleton's store. Judge Curwen complained of Thomp- son's fair appearance and uncandid behaviour. He must have keenly felt the singular reversal in their relations. 'This young man,' says the judge, 'when a shop-lad to my next neighbour, eve'- appeared active, good-natured, 108 COUNT RUMFORD. and sensible ; by a strange concurrence of events, he is now Under-Secretary to the American Secretary of State, Lord George Germain, a Secretary to Georgia, Inspector of all the clothing sent to America, and Lieutenant- Colonel Commandant of Horse Dragoons at New York ; his income from these sources is, I have been told, near TjOOO^. 1 a year a sum infinitely beyond his most sanguine expectations.' As the prospects of the war darkened, Thompson's patron in England became more and more the object of attack. The people had been taxed in vain. England was entangled in Continental war, and it became gra- dually recognised that the subjugation of the colony was impossible. Burgoyne had surrendered, and the issue of the war hung upon the fate of Cornwallis. On October 19 he also was obliged to capitulate. The effect of the disaster upon Lord North, who was then Prime Minister, is thus described by Sir M. W. Wrax- all : ' The First Minister's firmness, and even his pre- sence of mind, gave way for a short time under this awful disaster. I asked Lord George afterwards how he took the communication. " As he would have taken a ball in his breast," replied Lord George ; " he opened his arms, exclaiming wildly, as he paced up and down the apartment during a few minutes, ' God ! it is all over I"" To Thompson's credit be it recorded, that he showed no tendency to desert the cause he had espoused when he found it to be a failing one. In 1782 his chief was driven from power. At this critical time he accepted the commission of lieutenant-colonel in the British army, and returned to America with a view of rallying for a final stand such forces as he might find capable of organisation. He took with him four pieces of 1 This Dr. Ellis considers to be a delusion. COUNT KUMFORD. 109 artillery, with which he made experiments during the voyage. His destination was Long Island, New York, but stress of weather carried him to Charleston, South Carolina. ' Obliged,' says Pictet, ' to pass the winter there, he was made commander of the remains of the cavalry in the Royal army, which was then under the orders of Lieutenant-General Leslie. This corps was broken, but he promptly restored it, and won the confi- dence and attachment of the commander. He led them often against the enemy, and was always successful in his enterprises.' About the middle of April Thompson reached New York, and took command of the King's American Dragoons. Colours were presented to the regiment on August 1 , a very vivid account of the ceremony being given in Rivington's ' Royal Gazette ' of August 7, 1782. Prince William Henry, afterwards King William IV., was there at the time. The regiment passed in review before him, performing marching salutes. They then returned, dismounted, and formed in a semicircle in front of the canopy. After an address by their chaplain, the whole regiment knelt down, laid their helmets and arms on the ground, held up their right hands, and took a most solemn oath of allegiance to their sovereign, and fidelity to their standard. From Admiral Digby the Prince received the colours, and presented them with his own hands to Thompson, who passed them on to the oldest cornets. < On a given signal the whole regiment, with all the numerous spectators, gave three shouts, the music played " God save the King," the artillery fired a royal salute, and the ceremony was ended.' Many complaints have been made of the behaviour of the troops during their stay at Long Island, New York. But war is always horrible ; and it is pretty 110 COUNT RUMFORD. clear from the account of Dr. Ellis, that the complaints had no other foundation than events inseparable from the carrying on of war. In the statement of Thompson's case his biographer, extenuating nothing, and setting down naught in malice, winds up his third chapter with these words : ' I may add to sue 5 : praise as is due to him as a good soldier, quick and true and bold in action, and faithful to the Government which he served, the higher tribute that, from the hour when the war closed, he became, and ever continued to be, the constant friend and generous benefactor of his native country.' Early in April 1783 Thompson obtained leave to return to England, but finding there no opportunity for active service, he resolved to try his fortune on the Con- tinent, intending to otfer his services as a -volunteer in the Austrian army against the Turks. The historian Gibbon crossed the Channel with him. In a letter dated Dover, September 1 7, 1783, Gibbon writes thus : * Last night the wind was so high that the vessel could not stir from the harbour; this day it is brisk and fair. We are flattered with the hope of making Calais Har- bour by the same tide in three hours and a half; but any delay will leave the disagreeable option of a tottering boat or a tossing night. What a cursed thing to live in an island ! this step is more awkward than the whole journey. The triumvirate of this memorable embarka- tion will consist of the grand Gibbon ; Henry Laurens, Esq., President of Congress ; and Mr. Secretary, Colonel, Admiral, Philosopher Thompson, attended by three horses, who are not the most agreeable fellow-passengers. If we survive, I will finish and seal my letter at Calais. Our salvation shall be ascribed to the prayers of my lady and aunt, for I do believe they both pray.' The 'grand Gibbon' is reported to have been terribly COUNT BUMFORD. Ill frightened by the plunging of his fellow-passengers, the three blood-horses. Thompson pushed on to Strasburg, where Prince Maximilian of Bavaria, then a field-marshal in the service of France, was in garrison. As on a former occasion in his native country, Thompson, mounted on one of his chargers, appeared on the parade-ground. He attracted the attention of the Prince, who spoke to him, and on learning that he had been serving in the American war, pointed to some of his officers, and re- marked that they had been in the same war. An animated conversation immediately began, at the end of which Thompson was invited to dine with the Prince. After dinner, it is said, he produced a portfolio con- taining plans of the principal engagements, and a col- lection of excellent maps of the seat of war. Eager for information, the Prince again invited him for the next day, and when at length the traveller took leave, engaged him to pass through Munich, giving him a friendly letter to his uncle, the Elector of Bavaria. Thompson carried with him wherever he went the stamp of power and the gift of address. The Elector, a sage ruler, saw in him immediately a man capable of rendering the State good service. He pressed his visitor to accept a post half military, half civil. The proposal was a welcome one to Thompson, and he came to England to obtain the King's permission to accept it. Not only was the permission granted, but on February 23, 1784, he was knighted by the King. Dr. Ellis publishes the * grant of arms ' to the new knight. In it he is described as ' Son of Benjamin Thompson, late of the Province of Massachusetts Bay in New England, Gent., deceased,' and as ' of one of the most antient Families in North America ; that an Island which belonged to 112 COUNT RUMFORD. his Ancestors, at the entrance of Boston HarJbour, where the first New England Settlement was made, still bears his name ; that his Ancestors have ever lived in reputable Situations in that country where he was born, and have hitherto used the Arms of the antient and respectable Family of Thompson, of the county of York, from a constant Tradition that they derived their Descent from that Source.' The original parchment, perfect and unsullied, with all its seals, is in the possession of Mrs. James F. Baldwin, of Boston, widow of the executor of Countess Sarah Eumford. 1 The knight himself, observes his biographer, must have furnished the infor- mation written on that flowery and mythical parchment. Thompson was fond of display, and he here gave rein to his tendency. He returned to Munich, and on his arrival the Elector appointed him colonel of a regiment of cavalry and general aide-de-camp to himself. He was lodged in a palace, which he shared with the Russian Ambassador, and had a military staff and a corps of servants. * His imposing figure, his manly and handsome countenance, his dignity of bearing, and his courteous manners, not only to the great, but equally to his subordinates and inferiors, made him exceedingly popular.' He soon acquired a mastery of the German and French languages. He made himself minutely ac- quainted with everything concerning the dominions of the Elector their population and employments, their resources and means of development, and their relations to other powers. He found much that needed removal and required reformation. Speaking of the Electorate, Cuvier remarks that ' its sovereigns had encouraged devotion, and made no stipulation in favour of industry. There were more convents than manufactories in their ' Ellia. COUNT RUMFORD. 113 States ; their army was almost a shadow, while ignorance and idleness were conspicuous in every class of society.' Thompson evoked no religious animosity. He avowed himself a Protestant, but met with no opposition on that score. Holding as he did the united offices of Minister of War, Minister of Police, and Chamberlain of the Elector, his influence and action extended to all parts of the public service. Then, as now, the armies of the Continent were maintained by conscrip- tion. Drawn away from their normal occupations, the peasants returned after their term of service lazy and demoralised. This was a great difficulty ; and in dealing with it patient caution had to be combined with adminis- trative skill. Four years of observation were spent at Munich before Thompson attempted any thing practical. The pay of the soldiers was miserable, their clothing bad, their quarters dirty and mean ; the expense being out of all proportion to the return. The officers, as a general rule, regarded the soldiers as their slaves ; and here special prudence was necessary in endeavouring to effect a change. Thompson induced the more earnest among the officers to co-operate with him, by making the pro- posed reforms to originate apparently with them. He aimed at making soldiers citizens and citizens soldiers. The situation of the soldier was to be rendered pleasant, his pay was to be increased, his clothing rendered com- fortable and even elegant, while all liberty consistent with strict subordination was to be permitted him. Within, the barracks were to be neat and clean ; and with- out, attractive. Reading, writing, and arithmetic were to be taught, not only to the soldiers and their children, but to the children of the neighbouring peasantry. The paper used in the school would, it was urged, be practically free of cost, as it would serve afterwards for cartridges. 114 COUNT BUMFOED. The marshes near Mannheim were dreary bogs, use- less for cultivation and ruinous to the health of the city. Thompson drained them, banked them in, and converted them into a garden for the use of the garrison. For the special purpose of introducing the culture of the potato, he extended the plan of military gardens to all other garrisons. The gardens were tilled, and their produce was owned by noncommissioned officers and privates, each of whom had a plot of 365 square feet allotted to him. Gravel walks divided the plots from each other. The plan proved completely successful. Indolent soldiers became industrious, while soldiers on furlough, spreading abroad their taste and knowledge, caused little gardens to spring up everywhere over the country. Having secured this end, he converted it into a means of suppressing the enormous evils of mendicity. Bavaria was infested with beggars, vagabonds, and thieves, native and foreign. These mendicant tramps were in the main stout, healthy, and able-bodied fellows, who found a life of thievish indolence pleasanter than a life of honest work. ' These detestable vermin had recourse to the most diabolical arts and the most horrid crimes in the prosecution of their infamous trade. They robbed, and maimed and exposed little children, so as to extract money from the tender-hearted. In the cities the beggars formed a distinct caste, with profes- sional rules to guide them. Their training was a training in robbery ; the means they employed for extoitiug support being equivalent to direct plunder. Seeing no escape from the incubus, the public had come to bow to it as a necessity. The energy with which Thompson grappled with this evil may be inferred from the fact that out of a population of sixty thousand, two thousand six hundred beggars were impounded in a single week. COUNT RUMFORD. 115 Four regiments of cavalry were so cantoned thai every village in Bavaria and the adjoining provinces had a patrol party of four or five mounted soldiers 'daily coursing from one station to another.' The troopers were under strict discipline, extreme care being taken to avoid collision with the civil authorities. This disposition of the cavalry was antecedent to seizing, as a beginning, all the beggars in the capital. Aged and infirm mendicants were carefully distinguished from the sturdy and able-bodied. Voluntary contributions were essential, but the inhabitants, though groaning under the load of mendicancy, had been so often disappointed in their efforts to get rid of it that they now held back. Thompson resolved to give proof of success before asking for general aid. He interested persons of high rank in his scheme ; organised a bureau to relieve the needy and employ the idle. The members of his committee were presidents of the great offices of State, who worked without pay. The city was divided into sixteen districts, with a committee of charity for each ; while a re- spected citizen, assisted by a priest and a physician, serving gratuitously, looked after the worthy poor. He knew perfectly well that in Munich many be- quests consecrated to charity were being abused and wasted, but he cautiously abstained from meddling with them. The problem before him might well have daunted a courageous man. It was neither more nor less than to convert people bred up in lazy and dissolute habits into thrifty workers. Precepts, he knew, were unavailing, so his aim was to establish habits. Eeversing the maxim that people must be virtuous to be happy, he made his beggars happy as a step towards making them virtuous. He affirmed that he had learnt the importance of cleanli- ness through observing the habits of birds and beasts. 116 COUHT RUMFORD. Lawgivers and founders of religions ne^er failed to recognise the influence of cleanliness on man's moral nature. ' Virtue,' he said, ' never dwelt long with filth and nastiness, nor do I believe there ever was a person scrupulously attentive to cleanliness who was a consum- mate villain.' He had to deal with wretches covered with filth and vermin, to cleanse them, teach them, and give them the pleasure and stimulus of earning money. He did not waste his means on fine buildings, but taking a deserted manufactory, he repaired it, enlarged it, adding to it kitchen, bakehouse, and workshops for mechanics. Halls were provided for the spinners of flax, cotton, and wool. Other halls were set up for weavers, clothiers, dyers, saddlers, wool-sorters, carders, combers, knitters, and seamstresses. The next step was to get the ediflce filled with suitable inmates. New Year's Day was the beggars' holiday, and their reformer chose that day to get hold of them. It was the 1st of January, 1790. In the prosecution of his despotic scheme all men seemed to fall under his lead. To relieve it of the odium which might accrue if it were effected wholly by the military, he associated with himself and his field officers the magistrates of Munich. They gave him willing sym- pathy and aid. On New Year's morning he and the chief magistrate walked out together. With extended hand a beggar immediately accosted them. Thompson, setting the example to his followers, laid his hand gently upon the shoulder of the vagabond, committed him to the charge of a sergeant, with orders to take him to the Town-hall, 'where he would be provided for in one way if he were really helpless, but in another way if he were not.' Thompson encouraged his associates, and with such alacrity was the work accomplished, that at the end of that day not a single beggar remained at COUNT RUMFORD. 117 large. The name of every member of the motley crew was inserted in prepared lists, and they were sent off to their haunts with instructions to appear on the following day at the military workhouse, where they would inhabit comfortable warm rooms, enjoy a warm dinner daily, and be provided with remunerative work. In the suburbs the same measures were followed up successfully by patrols of soldiers and police. With his iron resolution was associated, in those days, a plastic tact which enabled him to avoid jealousies and collisions that a man of more hectoring temper and less self-restraint would infallibly have incurred. To the schools for poor students, the Sisters of Charity, the hospital for lepers, and other institutions, had been conceded the right of making periodic appeals from house to house ; German apprentices had also been permitted to beg upon their travels ; all of these had their claims adjusted. After he had swept his swarm of paupers into the quarters provided for them, Thompson's hardest work began. Here the inflexible order which characterised him through life came as a natural force to his aid. ' He encouraged a spirit of industry, pride, self-respect, and emulation, finding help even in trifling distinctions of apparel.' His pauper workhouse was self-supporting, while its inmates were happy. For several years they made up all the clothing of the Bavarian troops, realising sometimes a profit of 10,000 florins a year. Thompson himself constructed and arranged a kitchen which provided daily a warm and nutritious dinner for a thousand or fifteen hundred persons, an incredibly small amount of fuel sufficing to cook a dinner of this magnitude. The military work- house was also remunerative. Its profits for six years exceeded a hundred thousand dollars. The military workhouse at Mannheim was unfortunately set on fire 118 COUNT BUMFORD. and ruined during the siege of the city by Austrian troops. Thompson had the art of making himself loved and honoured by the people whom he ruled in this arbitrary way. Some very striking illustrations of this are given in the ' Life and Essays.' He once, for example, broke down at Munich under his self-imposed labours. It was thought that he was dying, and one day while in this condition, his attention was attracted by the con- fused noise of a passing multitude in the street. It was the poor of Munich who were going in procession to the church to offer public prayers for him. * Public prayers I ' he exclaims, ' for me, a private person, a stranger, a Protestant ! ' Four years afterwards, when he was dangerously ill at Naples, the people of their own accord set apart an hour each evening, after they had finished their labours in the military workhouse, to pray for his recovery. Men find pleasure in exercising the powers they possess, and Rumford possessed, in its highest and strongest form, the power of organisation. The relief of the poor, which occupied his attention for years, was pursued by him as a scientific inquiry. He differen- tiated the people who had fair claims upon the State from those whose infirmity and incapacity rendered con- tinuous assistance necessary, but \vho could not be aided by compulsory taxation. In this case the promptings of humanity must be invoked. Persons of high rank ought here to take the lead, combining with those im- mediately below them to secure efficient supervision and relief. The expense thus incurred is small compared with that incidental to beggary and its concomitant thieving. Thompson's hope and confidence never for- sook him. He faced, uuquailing, problems from which less daring spirits would have recoiled. He held, un- COUNT RUMFORD. 119 doubtingly, that 'arrangement, method, provision for the minutest details, subordination, co-operation, and a careful system of statistics, will facilitate and make effective any undertaking, however burdensome and comprehensive.' Such a statement would surely have elicited a ' bravo ! ' from Carl vie. In Thompson, flexible wisdom formed an amalgam with despotic strength. With skill and resolution the objects of public benevo- lence must, he urged, be made to contribute as far as possible to their own support. The homeliest details did not escape him. He commended well-dressed vegetables as a cheap and wholesome aliment. He descanted on the potato, he gave rules for the construc- tion of soup-kitchens, and determined the nutritive value of different kinds of food. During his bovhood at Woburn he had learnt the use of Indian corn, and at Munich he strongly recommended the dump- lings, bread, and hasty pudding made from maize. Pure love of humanity would, at first sight, seem to have been the motive force of Thompson's action. Still, it has been affirmed by those who knew him that he did not really love his fellow-men. His work had for him the fascination of a problem above the capacities of most men, but which he felt himself able to solve. It was said to be the work of his intellect, not of his heart. In reference to him, Cuvier quotes what Fon- tenelle said of Dodard, who turned his rigid observance of the fasts of the Church into a scientific experiment on the effects of abstinence, thereby taking the path which led at once to heaven and into the French Academy. I should hesitate before accepting this as a complete account of Rumford's motives. In the north-easterly environs of Munich a wild and neglected region of forest and marsh, which had formerly been the hunting-ground of the Elector, was 120 COUNT RUMFORD. converted by Thompson into an 'English garden.' Pleasure-grounds, parks, and fields were laid out, and surrounded by a drive six miles long. Walks, pro- menades, grottos, a Chinese pagoda, a racecourse, and other attractions were introduced ; a lake was formed and a mound raised ; while a refreshment-saloon, hand- somely furnished, provided for the creature comforts of the visitors. Here during Rumford's absence in England in 1795, and without his knowledge, a monu- ment was raised to commemorate his beneficent achieve- ments. ' It stands within the garden, and is composed of Bavarian freestone and marble. It is quadrangular, its two opposite fronts being ornamented with basso- relievos, and bearing inscriptions.' The wanderer on one side is exhorted to halt, while thankfulness streng- thens his enjoyment. 'A creative hint from Carl Theodor, seized upon with spirit, feeling, and love by the friend of man, Eumford, has ennobled into what thou now seest this once desert region.' On the other side of the monument is a dedication to ' Him who eradicated the most scandalous of public evils, Idleness and Mendicity; who gave to the poor help, occupation, and morals, and to the youth of the Fatherland so many schools of culture. Gro, wanderer I try to emulate him in thought and deed, and us in gratitude.' Rumford's health, as already indicated, had given way, and in 1793 he went to Italy to restore it. He was absent for sixteen months, and during his absence was seriously ill at Naples. Had he been less filled with his projects, it might have been better for his health. Had he known how to employ the sanative power of Nature, he would have kept his vigorous frame longer in working order. But the mountains of Mag- giore were to him less attractive than the streets of COUNT RUMFORD. 121 Verona, where he committed himself to the planning of soup-kitchens. He made similar plans for other cities, BO that to call his absence a holiday would be a mis- nomer. He returned to Munich in August 1794, slowly recovering, but not "able to resume the management of his various institutions. In September 1795 he re- turned to London, after an absence of eleven years. Dr. Ellis describes him as 'the victim of an outrage ' on his arrival, the meaning of which seems to be that the trunk containing his papers, which was carried behind his carriage, was appropriated by London thieves. * By this cruel robbery,' he says, ' 1 have been deprived of the fruits of the labours of my whole life. . . . It is the more painful to me, as it has clouded my mind with suspicions that can never be cleared up.' What the suspicions were we do not know. Soon afterwards he was invited by Lord Pelham, then Secretary of State for Ireland, to visit him in Dublin ; he went, and during his two months' stay there busied himself with improvements of warming, cooking, and ventilation, in the hospitals and workhouses of the city. He left behind him a number of models of useful mechanism. The Eoyal Irish Academy elected him a member. The grand jury of Dublin presented him with an address ; while the Viceroy and the Lord Mayor wrote to him. officially to thank him for his services. Dr. Ellis has not been able to find these documents, but they were seen by Pictet, who describes them aa * filled with the most flattering expressions of esteem and gratitude.' In Rumford's case the life of the intellect appeared to have interfered with the life of the affections. When he quitted America, he left his wife and infant daughter brhind him, and whether any communication after- wards occurred between him and them is not known. 122 COUNT RUMFORD. In 1793, in a letter to his friend Baldwin, he expressed the desire to visit his native country. He also wished exceedingly to be personally acquainted with his daugh- ter, who was then nineteen. His affection for his mother, which appears to have been very real, also appears in this letter. With reference to the projected visit, he asks, ' Should I be kindly received ? Are the remains ot party spirit and political persecution done away ? Would it be necessary to ask leave of the State ? ' A year prior to the date of this letter, Rum- ford's wife had died at the age of fifty-two. On January 29, 1796, his daughter sailed for London to see her father. She bad a tedious passage, but soon after her arrival she writes to her friend Mrs. Baldwin, 'All fatigue and anxiety are now at an end, since my dear father is well and loves me.' In a history of her life, written many years after- wards, she, however, describes the disappointment she experienced on first meeting her father. Her imagi- nation had sketched a fancy picture of him. She ' had heard him spoken of as an officer, and had attached to this an idea of the warrior with a martial look, possibly the sword, if not the gun, by his side.' All this disappeared when she saw him. He did not strike her as handsome, or even agreeable a result in part due to the fact that he had been ill, and was very thin and pale. She speaks, however, of his laughter * quite from the heart,' while the expression of his mouth, with teeth described as 'the most finished pearls,' was sweetness itself. He did not seem to manage her very successfully. She had little knowledge of the world, and her purchases in London he thought both extravagant and extra- ordinary. After having, by due discipline, learnt how to make an English courtesy, to the horror of her tjither, almost the first use she made of her newly- COUNT EUMFOED. 123 acquired accomplishment was to courtesy to a house- keeper. His labours in the production of cheap and nutritious food necessarily directed Eumford's attention to fire- places and chimney-flues. When he published his essay on this subject in London, he reported that he had not less than five hundred smoky chimneys on his handa His aid and advice were always ready, and were given indiscriminately to all sorts and conditions of men. Devonshire House, Sir Joseph Banks's, the Earl of Bess- borough's, Countess Spencer's, Melbourne House, Lady Templeton's, Mrs. Montagu's, Lord Sudley's, theMarquis of Salisbury's, and a hundred and fifty other houses in London, were placed in his care. The saving of fuel, with gain instead of loss of warmth, varied in these cases from one-half to two- thirds. ' Giving very simple and intelligible information about the philosophical principles of combustion, ventilation, and draughts, he prepared careful diagrams to show the proper measure- ments and arrangements of all the parts of a fireplace and flue. He took out no patent for his- inventions, but left them free to the public. In a poem published at this time by Thomas James Matthias we have the following reference to the labours of Rumford : Nonsense, or sense, I'll bear in any shape In gown, in lawn, in ermine, or in crape : What's a fine type, where truth exerts her rule f Science is science, and a fool's a fool. Yet all shall read, and all that page approve, When public spirit meets with public love. Thus late, where poverty with rapine dwelt, Eumford's kind genius the Bavarian felt, Not by romantic charities beguiled, Bat calm in project, and in mercy mild ; Where'er his wisdom guided, none withstood, Content with peace and practicable good ; Bound him the laboureis throng, the nobles wait. Friend of the poor, and guardian of the State. 124 COUNT KUMFORD. The pall of smoke which habitually hung over London, ' covering all its prominent edifices with a dingy and sooty mantle,' curiously and anxiously interested him. He * saw in that smoke the unused material which was turned equally to waste and made a means of annoyance and insalubrity.' He would bind himself, if the oppor- tunity were allowed him, * to prove that from the heat, and the material of heat, which were thus wasted, he would cook all the food used in the city, warm every apartment, and perform all the mechanical work done by means of fire.' Under this wasted heat Eumford would doubtless comprise both the imperfectly-con- sumed gases, such as carbonic oxide, and the heated air and other gases discharged by the chimneys. There is no doubt that the present age has entered largely into the labours of Rumtbrd. Many of the devices and conveniences now employed in our kitchens owe their origin to him. The practical needs and mechanical ingenuity of his own countrymen have caused them to follow his lead with conspicuous success. We have, for example, in our modest little kitchen in the Alps, an American oven which, with the expenditure of an extremely small amount of firewood, heats our baths, cooks our meat, bakes our bread, boils our clothes, and contributes to the warmth and comfort of the house. This arrangement traces its pedigree to Rumford. In 1796 he founded the historic medal which bears his name. On the 12th of July of that year he wrote thus to Sir Joseph Banks, then President of the Royal Society : ' I take the liberty to request that the Royal Society would do me the honour to accept of 1,OOOL stock in the Funds of this country, which I have actually purchased, and which I beg leave to transfer to the President, Council, and Fellows of the Royal Society, COUNT KUMFORD. 125 to the end that the interest of the same may be by them, and by their successors, received from time to time for ever, and the amount of the same applied and given once every second year, as a premium to the author of the most important discovery or useful improvement which shall be made, or published by printing, or in any way made known to the public, in any part of Europe, during the preceding two years, on Heat or Light.* He adds in a subsequent letter, as further defining his wishes, that the premium should be limited to new discoveries tending to improve theories of Fire, of Heat, of Light, and of Colours, and to new inventions and contrivances by which the generation, and preservation, and management of heat and of light may be facilitated. The device and inscriptions on the medal were deter- mined by a committee. It was resolved 'that the diameter of the medal do not exceed three inches, and that Mr. Milton be employed in sinking the dies of the said medal.' Two medals are always given, one of gold, the other of silver, and a sum of about seventy pounds usually accompanies the medals. Eumford him- self was the first recipient of the medal. The second was given to Sir John Leslie, the founder's celebrated rival in the domain of radiant heat. On the same date Eumford presented to the American Academy of Arts and Sciences the same sum for the promotion of the same object. In fact, the letters to Sir Joseph Banks and to the Honourable John Adams, then President of the American Academy, are identical in terms. For a long series of years the American Academy did not con- sider that the candidates for the medal had reached the level of merit which would justify its award. No award was therefore made; and in 1829 the Rutnford bequest had increased from five thousand to twenty thousand dollars. After some litigation the terror of the bequest 126 COUNT RUMFORD. were extended to embrace applications of it far beyond the design of the testator. Permission was obtained to apply the fund to the publication of books, or methods of discovery, bearing on the Count's favourite subjects of experiment ; and to the aid and reward of scientific workers. Thus, in 1839, Dr. Hare, of Philadelphia, re- ceived from the Academy six hundred dollars for his invention of the compound blow-pipe, and his improve- ments in galvanic apparatus. In 1862 the Kumford medal was awarded to Mr. John B. Ericsson, for his caloric engine; while Mr. Alvan Clark, so celebrated for his improvements of the refracting telescope, and the eminent Dr. John Draper, of the University of New York, have been also numbered among the recipients. Accompanied by his daughter, Rumford returned to Germany in 1796. 'Three weeks' constant travel; circuitous routes to avoid troops, bad roads, still worse accommodations passing nights in the carriages for the want of an inn scantiness of provisions, joined with great fatigue, rendered our journey by no means agree- able.' At Munich they were lodged in the splendid house allotted to the Count. France and Austria were then at war, while Bavaria sought to remain rigidly neutral. Eight days after Rumford's arrival, the Elector took refuge in Saxony. Moreau had crossed the Rhine and threatened Bavaria. After a defeat by the French, the Austrians withdrew to Munich, but found the gates of the city closed against them. They planted batteries an a height commanding the city. According to arrange- ment with the Elector, Rumford assumed the command of the Bavarian forces, and by his firmness and presence of mind prevented both French and Austrians from entering Munich. A foreigner acting thus was sure to excite jealousy and encounter opposition ; but, despite all this, he was eminently successful in realising his COUNT RUMFOBD. 127 aims. The consideration in which he was held by the Elector is illustrated by the fact that he made Miss Thompson a Countess of the Empire, conferring on her a pension of 2001. a year, with liberty to enjoy it in any country where she might wish to reside. The following incident is worth recording. In March 1796, JRumford's daughter, wishing to celebrate his birthday, chose out of his workhouse a dozen of the most industrious little boys and girls, dressed them up in the uniform of that establishment, and robing herself in white, led them into his room and presented them to him. He was so much touched by the incident, that he made her a present of two thousand dollars (400Z.) on condition that she should, in her will, apply the interest of the sum to the clothing every year for ever, on her own birthday, of twelve meritorious children six girls and six boys in the Munich uniform. The poor children were to be chosen from her native town, Concord. Habit must to some extent have blinded Kumford's eyes to the objection which independent New Englanders were likely to make to this fantastic apparel. They bluntly stated their objections, but ' with grateful hearts ' they nevertheless expressed their willingness to accept the donation. Nothing further was done during Rumford's lifetime. The New England girl, brought up in Concord, transplanted thence to London, arid afterwards to Munich, was subjected to a trying ordeal. After a short period of initiation, she appears to have passed through it creditably. Her writing does not exhibit any marked qualities of intellect. She was bright, gossipy, ' volatile,' and she throws manifold gleams on the details of Rumford's life. He constantly kept a box at the opera, though he hardly ever went there, and hired by the year a doctor named Haubenal. She amusingly describes a quintuple present made to 128 COUNT RUMFORD. her by her father soon after her arrival in Munich The first item was ' a little shaggy dog, as white as snow, excepting black eyes, ears, and nose ' ; the second was a lady named Veratzy, who was sent to teach her French and music; the third was a Catholic priest, named Dillis, who was to be her drawing-master ; -the fourth was a teacher of Italian, named Alberti ; and the fifth, the before-mentioned Dr. Haubenal, who was to look after her health. She did not at all like the arrange- ment. She was particularly surprised and shocked at a doctor's offering his services before they were wanted. 'Said I to myself, Surrounded by people who speak French and all genteel people speak it at Munich and knowing considerable of the language already, where is the use of my fatiguing myself with masters ? Music the same.' In fact, the little dog ' Cora ' was the only welcome constituent of the gift. She describes with considerable spirit a ball which was organised to celebrate her father's birthday. All united to do him honour. Wreaths surrounded his bust; his workhouse children, joined by some children of the nobility, all dressed in white, handed addresses to him, and sang in accompaniment to the swell of music, of which he was passionately fond. All this was arranged without his knowledge, and possibly not without an intention to give dramatic force to a revelation to be made at the time. It was observed that Eumford had singled out from the children a little girl of eight, who accompanied him when he walked, and took her place beside him when he sat. The little girl was his illegiti- mate child. Sarah, on learning this, threw herself into the dance she had previously declined, and thus whirled away her indignation. Her partner was the young Count Taxis, Rumford's aide-de-camp, between whom and Rumford's daughter a friendly intimacy was obviously COUNT RUMFORD. 129 growing up. Rumford noticed this, and disapproved oi it. Being invited to dinner at the house of the Countess Lerchenfeld, with her father's consent Miss Thompson went. Count Taxis happened to be one of the party, and on hearing this Eumford jumped to the conclusion that a ladies' conspiracy was afoot to counteract his wishes. With a lowering look he taxed his daughter with what he supposed to be an intrigue. At first she could only stare at him in surprise. ' After which, on knowing what it meant, like many young people who laugh when there is nothing to laugh at, an irresistible inclination seized me to laugh.' She gave way to her inclination, 'and it ended in my father's boxing my ears.' She was stunned by the indignity, and ' quitted the room, without making an observation, or trying to appease him by saying I was innocent.' The Elector put the seal to his esteem for Rumford by appointing him as Plenipotentiary from Bavaria to the Court of London. King George, however, declined to accept him in this capacity. Mr. Paget, the Minister at the Court of Bavaria, was desired ' to lose no time in apprising the Ministers of His Electoral Highness that such an appointment would be by no means agreeable to His Majesty, and that His Majesty relies therefore on the friendship and good understanding which have always hitherto subsisted between himself and the Elector of Bavaria, and that His Highness will have no hesitation in withdrawing it.' The King had made up his mind. ' Should there unexpectedly arise any difficulty about a compliance with the request, which His Majesty is so clearly warranted in making, I am to direct you, in the last resort, to state in distinct terms that His Majesty will by no means consent to receive Count Rumford in the character which has been assigned to him.' The fact of Ilumford's being not only a British 130 CX)UNT RUMFORD. subject, but that he had actually filled a confidential situation under the British Government, was cited aa rendering his appointment peculiarly objectionable. Some correspondence ensued between Lord Grenville and Rumford, but the appointment was not ratified. Stung by the refusal of King George to accept him as Bavarian Minister, the thought, which had often occurred to him, of returning to his native country now revived. Mr. Eufus King was at that time American Ambassador in London ; and he, by Rumford's desire, wrote to Colonel Pickering, then Secretary of State for the United States, informing him that intrigues in Bavaria, and the refusal of the English king, had caused the Count to decide on establishing himself at, or near, Cambridge, Massachusetts. Mr. King described the Count's intention to live in the character of a German nobleman, renouncing all poli- tical action, and devoting himself to literary pursuits. He observed that Rumford had much experience of cannon foundries, and had made important improve- ments in the mounting of flying artillery. He was, moreover, the possessor of an extensive military library, and wished nothing more ardently than to be useful to his native country. Provision had been made for the institution of a military academy in the United States. This they offered to place under the superin- tendence of Eumford. 'I am authorised,' said Mr. King, * to offer you, in addition to the superintendence of the military academy, the appointment of Inspector- General of the Artillery of the United States ; and we shall moreover be disposed to give to you such rank and emoluments as would be likely to afford you satisfac- tion, and to secure to us the advantage of your service.' The hour for the final decision approached, but before it arrived another project had laid hold of Rum- COUNT RUMFORD. 131 ford's imagination a project which in its results has proved of more importance to science, and probably of more advantage to mankind, than any which this multi- farious genius had previously undertaken. This project was the foundation of the Eoyal Institution of Great Britain. In answer to the American Ambassador, he says, ' Nothing could have afforded me so much satisfaction as to have had it in my power to have given to my liberal and generous countrymen such proof of my sen- timents as would, in the most public and ostensible manner, have evinced, not only my gratitude for the kind attentions I have received from them, but also the ardent desire I feel to assist in promoting the pro- sperity of my native country; but engagements, which great obligations have rendered sacred and inviolable, put it out of my power to dispose of my time and ser- vices with that unreasoned freedom which would be necessary in order to enable me to accept of those generous offers which the Executive Government of the United States has been pleased to propose to me.' The climate of Europe, however, did not seem to suit Eumford's daughter. Possibly also the simple tastes and habits of her childhood were too deeply ingrained in her constitution to permit of her deriving any real enjoyment from the outsided, and apparently noisy life which she was forced to lead in Munich and London. Be this as it may, she returned to America, reaching the port of Boston on October 10, 1799, 'being then just twenty-five years of age.' Eumford himself remained in England with the view of realising what I have called the greatest project of his life the found- ing of the Koyal Institution. His ideas on this subject took definite shape in 1799. They were set forth in a pamphlet of fifty pages, bear- 132 COUNT KUMFORD. ing the following lengthy title : ' Proposals for forming by subscription, in the Metropolis of the British Empire, a Public Institution for diffusing the Knowledge and facilitating the general Introduction of Useful Mechani- cal Inventions and Improvements, and for teaching, by courses of Philosophical Lectures and Experiments, the Application of Science to the Common Purposes of Life.' The introduction to this pamphlet is dated from Rum- ford's residence in Brompton Row, March 4, 1799. His aim, he alleges, is to cause science and art to work together ; to establish relations between philosophers and workmen ; to bring their united efforts to bear in the improvement of agriculture, manufactures, com- merce, and the augmentation of domestic comforts. He specially dwells on the management of fire, it being, as he thinks, a subject of peculiar interest to mankind. Fuel, he asserted, costs the kingdom more than ten millions sterling annually, which was much more than twice what it ought to cost. Eumford knew human nature well, and for the greater portion of hia life knew how to appeal to it with effect. In fact, the knowledge never failed him, though towards the end irritability, due to ill-health and crosses of various kinds, rendered him less able to apply the knowledge than when he was in the blossom of his prime. As regards the success of his new scheme, he urged upon those with whom he acted the necessity of making the indo- lent and luxurious take an interest in it. Such persons, he says, ' must either be allured or shamed into action.' Hence, he urges, the necessity of making benevolence ' fashionable.' It ought to be mentioned that Rumford, at this time, could count on the sympathy and active support of a number of excellent men, who, in advance of him, bad founded a ' Society for Bettering the Condition and COUNT BUMFOBD. 133 Increasing the Comforts of the Poor.' The aid of the committee of this society was now sought. It was agreed on all hands that the proposed new Institution would be too important to permit of its being made an ap- pendage to any other. It was resolved that it should stand alone. A committee consisting of eight members of the above society was, however, appointed to confer with Rumford regarding his plan. To each member of this committee he submitted a statement of his views. These are in part set forth in the title to his pamphlet already quoted. The aim of the Institution, further- more, was * to excite a spirit of improvement among all ranks of society, and to afford the most effectual assistance to those who are engaged in the various pur- suits of useful industry.' He begged, however, that His Majesty's Ministers might be informed of the intention of the founders of the Institution to accept his services. This he deemed necessary because of his being, in the first place, a subject of His Majesty, and also, by His Majesty's special permission, the servant of a foreign prince. The Government was to be fully informed, not only as to the general aims, but also of the details of the scheme. Not till then did he ask for the counte- nance and support necessary to carry it into execution. The committee met and ratified Rumford's pro- posals. They agreed that subscribers of fifty guineas each should be the perpetual proprietors of the Institu- tion ; that a contribution of ten guineas should secure the privileges of a life subscriber ; whilst a subscription of two guineas should constitute an annual subscriber. Besides other important rights, each proprietor was to receive two transferable tickets, admitting him to every part of the Institution, and to all the lectures and expe- riments. Each life subscriber was to receive one ticket, not transferable, securing free admission to every part 134 COUNT RUMFOKD. of the establishment, and to all lectures and experi- ments. An annual subscriber had a single ticket for a single year, but might at any time become a life sub- scriber by the additional payment of eight guineas. The managers, nine in number, were to be chosen by ballot by the proprietors. The managers were to be unpaid, and, without any pecuniary advantage to them- selves, they were held solemnly pledged to the faithful discharge of their duties. Three were to constitute a quorum, but in special cases six were required. A Committee of Visitors was also appointed, the same in number as the Committee of Managers, and holding office for the same number of years. The managers were to devote the surplus funds of the Institution to the purchase of models of inventions and improvements in the mechanical arts, a room in the Institution being devoted to the reception of them. The room still exists, and, though diverted from its original purpose, is still called ' the Model Room.' A general meeting of the proprietors was held at the house of Sir Joseph Banks, in Soho Square, on March 7, 1799. Fifty-eight persons, comprising men of distinction in science, members of Parliament and of the nobility, including one bishop, were found to have qualified as proprietors by the subscription of fifty guineas each. The prelate was the Bishop of Durham. The Committee of Managers was chosen, and they held their first meeting at the house of Sir Joseph Banks on March 9, 1799. Mr. Thomas Ber- nard, one of the most active members of the society from whose committee the first managers were chosen, was appointed Secretary. To Rumford and Bernard was delegated the duty of preparing a draught of a charter ; while Earls Morton and Spencer, Sir Joseph Banks, and Mr. Pelham, were requested *to lay the COUNT BUMFORD. 135 proposals before His Majesty, the Royal Family, the Ministers, the great officers of State, the members of both Houses of Parliament, of the Privy Council, and before the twelve judges.' On January 13, 1800, the Royal Seal was attached to the Charter of the Institution. In the same year was published, in quarto form, * The Prospectus, Char- ter, Ordinance, and Bye-laws of the Royal Institution of Great Britain.' The King was its Patron, and the first officers of the Institution were appointed by him. The Earl of Winchilsea was President. Lord Morton, Lord Egremont, and Sir Joseph Banks were Vice- Presidents. The managers, chosen by sealed ballot by the proprietors, were divided into three classes of three each ; the first class serving for one, the second for two, and the third for three years. The Earls of Bess- borough, Egremont, and Morton, respectively, headed the lists of the three classes. Rumford "himself was appointed to serve for three years. The three lists of Visitors were headed by the Duke of Bridgewater, Viscount Palmerston, and Earl Spencer respectively. That Rumford possessed the power of persuasion, and the infection of enthusiasm, is sufficiently demonstrated by this powerful list. But neither persuasion nor en- thusiasm might have been found availing had not his actual achievements in Bavaria occupied the back- ground. The first Professor of Natural Philosophy and Chemistry was Dr. Thomas Cfarnett, while the first Treasurer was Mr. Thomas Bernard. But this was not enough. A home and foreign secretary, legal counsel, a solicitor and a clerk, were added to the list. One rule established at this time has been adhered to with great fidelity to the present day. No political subject was to be mentioned in the lectures. In a somewhat florid style Rumford (for he was 138 COUNT RUMFORD. obviously the writer) descants on the name and objects of the new project. The word Institution is chosen because it had been least used previously, and because it best indicates the objects of the new society. The influence of the mechanical arts on the progress of civilisation and refinement is pointed out. and illustrated by reference to nations, provinces, towns, and even vil- lages, which thrive in proportion to the activity of their industry. * Exertion quickens the spirit of invention, makes science flourish, and increases the moral and physical powers of man.' The printing-press, naviga- tion, gunpowder, the steam-engine, are referred to as having changed the whole course of human affairs. The slowness with which improvements make their way among workmen is ascribed to the influence of habit, prejudice, suspicion, jealousy, dislike of change, and the narrowing effect of the subdivision of work into many petty occupations. But slowness is also due to the greed for wealth, the desire for monopoly, the spirit of secret intrigue exhibited among manufacturers. Between these two the philosopher steps in, whose busi- ness it is ' to examine every operation of Nature and art, and to establish genei-al theories for the direction and conducting of future processes.' But philosophers may become dreamers, and they have therefore habitu- ally to be called back to the study of practical questions which bear upon the ordinary pursuits of life. Science and practice are in short to interact, to the advantage of both. This object may be promoted by the offering of premiums, after the manner of the Society of Arts, 1 by the granting of patents ; and, finally, by the method of the new Institution the diffusion of the knowledge of useful mechanical inventions, and their introduction Into life. 1 Founded in 1763. COUNT EUMFORD. 137 One of the first practical steps taken towards the realisation of these ideas was the purchase of the house, or rather houses, in Albemarle Street in which we are now assembled, and their modification to suit the objects in view. Rumford's obvious intention was to found an Institute of Technology and Engineering. Mere de- scription was not sufficient. He demanded something visible and tangible, and therefore proposed that the Institution should be made a repository for models of all useful contrivances and improvements : cottage fire- places and kitchen utensils ; kitchens for farm-houses and for the houses of gentlemen ; a laundry, including boilers, washing, ironing, and drying-rooms ; German, Swedish, and Russian stoves ; open chimney fireplaces, with ornamental grates ; ornamental stoves ; working models * of that most curious and most useful machine, the steam-engine ' ; brewers' boilers ; distillers' coppers ; condensers ; large boilers for hospitals ; ventilating appa- ratus in hot-houses ; lime-kilns ; steam-boilers for pre- paring food for stall-fed cattle ; spinning-wheels ; looms ; agricultural implements ; bridges of various construc- tions ; human food ; clothing ; houses; towns ; fortresses; harbours ; roads ; canals ; carriages ; ships ; tools ; weapons; &c. Chemistry was to be applied to soils, tillage, and manures ; to the making of bread, beer, wine, spirits, starch, sugar, butter, and cheese ; to the pro- cesses of dyeing, calico-printing, bleaching, painting, and varnishing ; to the smelting of ores ; the formation of alloys ; to mortars, cements, bricks, pottery, glass, and enamels. Above all, ' the phenomena of light and heat those great powers which give life and energy to the universe powers which, by the wonderful process of combustion, are placed under the command of human beings will engage a profound interest.' In reference to the alleged size of the bed of Og, the 138 COUNT RUMFORD. king of Basan, Bishop Watson proposed to Tom Paine the problem to determine the bulk to which a human body may be augmented before it will perish by its own weight. As regards the projected Institution, Rumford surely had passed this limit, and by the ponderosity of his scheme had ensured either the necessity of change or the certainty of death. In such an establishment Davy was sure to be an iconoclast. He cared little for models not even for the apparatus with which his own best discoveries were made, but incontinently broke it up whenever he found it could be made subservient to further ends. * The' Journal of the Eoyal Institution ' was established at this time, and published under Rumford's direction. No private advertisements were to appear in it, but it was to be sold for threepence when its contents amounted to eight pages, and for sixpence when they amounted to sixteen. The experiments and experimental lectures of Davy were then attracting attention. Rumours of the young chemist reached Rumford through Mr. Under- wood and Mr. James Thompson. At Rumford's request Davy came to London. His life at the moment was purely a land of promise, but Rumford had the sagacity to see the promise, and the wisdom to act upon his in- sight. Nor was his judgmentrapidly formed; for several interviews, doubtless meant to test the youth, preceded his announcement to Davy, on February 16, 1801, of the resolution of the Managers, ' That Mr. Humphry Davy be engaged in the service of the Royal Institution, in the capacity of Assistant Lecturer in Chemistry, Direc- tor of the Chemical Laboratory, and Assistant Editor of the Journals of the Institution ; and that he be allowed to occupy a room in the house, and be furnished with coals and candles, and that he be paid a salary of 100 guineas per annum.' Rumford, moreover, held out to COUNT KUMFOED. 139 Davy the prospect, if he devoted himself entirely and permanently to the Institution, of becoming, in the course of two or three years, full Professor of Chemistry, with a salary of 300Z. per annum, ' provided,' he adds, ' that within that period you shall have given proofs of your fitness to hold that distinguished situation.' This promise of the professorship in two or three years was ominous for Dr. Garnett, between whom and the Mana- gers differences soon arose which led to his withdrawal from the Institution. Davy began his duties on Wednesday, March 11, 1801. He was allowed the room adjoining that occu- pied by Dr. Garnett, to whom he was to refund the expenses incurred in furnishing the room. The com- mittee of expenditure paid to Dr. Garnett 20l. 2s. 3d. for a new Brussels carpet, and \1l. 6s. for twelve chairs, the carpet and chairs being transferred to the room occupied by the Managers. ' Count Eumford reported further that he had purchased cheaper a second-hand carpet for Mr. Davy's room, together with such other articles as appeared to him necessary to render the room habitable, and among the rest a new sofa-bed, which, in order that it may serve as a model for imita- tion, has been made complete in all its parts.' The name of a man who has no superior in its annals now appears for the first time in connection with the Institution. Here also the sagacity of Kumford was justified by events. At the suggestion of Sir Joseph Banks he had an interview with Dr. Thomas Youn^, destined to become so illustrious as the decipherer of the Egyptian hieroglyphics, and, by the discovery of Interference, the founder of the undulatory theory of light. It was proposed to him, by Kumford, to accept an engagement as Professor of Natural Philosophy in the Institution, as Editor of its Journals, and as super- 10 140 COUNT RUMFORD. intendent of the house, at a salary of 300Z. per annum. Young accepted the appointment, and the Managers confirmed it by resolution on August 3, 1801 : ' Kesolved, that the Managers approve of the measures taken by Count Rumford ; and that the appointment of Dr. Young be confirmed.' Rumford's health fluctuated perpetually, and it was said at the time that this was due in some measure to the fanciful notions he entertained, and acted on, with regard to diet and exercise. But Dr. Young affirms that his habits in these respects were guided by his physicians. Many years ago, wishing to supplement my know- ledge of the Turkish bath, I referred to a paper of Rumford's which gave an account of a visit to Harrogate and his experience there. According to the rules of the place he had his bath in the evening, and went to bed immediately afterwards. He found himself restless and feverish ; the bath, indeed, seemed to do him more harm than good. An observant fellow-lodger had made, and had corrected the same experience. Acting on his advice, Rumford took his bath two hours before dinner, engaging afterwards in his usual work, or going out to have a blow on the common. So far from suffering chill from this exposure, he found himself invigorated by it. My own experience, I may say, corroborates all this. Rumford took the senses of man as he found them, and tried to enhance the gratifications thence derived : * To increase the pleasure of a warm bath he suggests the burning of sweet-scented woods and aromatic gums and resins in small chafing-dishes in the bathing-rooms, by which the air will be perfumed with the most pleasant odours.' He spiritedly defends this counsel : ' Effeminacy is no doubt very despicable, especially in a person who aspires to the character and COUNT RUMFOKD. 141 virtues of a man. But I see no cause for calling any- thing effeminate which has no tendency to diminish either the strength of the body, the dignity of the sentiments, or the energy of the mind. I see no good reason for considering those grateful aromatic perfumes, which in all ages have been held in such high estima- tion, as a less elegant or less rational luxury than smoking tobacco or stuffing the nose with snuff.' Kumford, for a year or so, occupied rooms in the Institution, but his private residence was in Brompton Row, described by his friend Pictet as being about a mile from London. Grass and trees grew in front of the house. The windows had a double glazing, and outside were placed vases of flowers and odorous shrubs. Pictet, who was Rumford's guest in 1801, minutely describes the whole arrangement of the house. Into Rumford's working-room, which overlooked the country, the light came through a set of windows arranged on the arc of a circle. The window-sills were arranged with flowers and shrubs, so that you might suppose yourself to be in the country, close to a garden bordered by a park. Pictet goes on to describe the various strokes of inge- nuity shown in the management of the fuel and fire- places. The beds, moreover, were disguised as elegant sofas. Under each sofa were two deep drawers contain- ing the bedding and other night-gear, all of which were hidden by a fringed valance. At night the sofa was converted in a few minutes into an excellent bed, while in the morning, with equal rapidity, the bed was transformed into an ornamental piece of furniture. Pictet occupied one-half of the charming dwelling. Perfect freedom was given and enjoyed, and the learned Genevese always tried to arrange his day's work so that he might, if possible, engage his friend on some subject of research common to them both* 142 COUNT RUMFORD. A portion of the motive force of a man of Rumfor 1*8 temperament may be described as irritability. During the possession of physical vigour and sound health, this force is held firmly by the will and directed by intelli- gence and tact. But when health slackens and physical vigour subsides, irritability often becomes an energy wanting adequate control. Rumford's success in managing all manner of men in Bavaria illustrates his pliancy as much as his strength. But before he started the Royal Institution his health had given way, and 1 tern per,' it is to be feared, bad got the upper hand. In point of intellect, moreover, he came then into con- tact with people of larger calibre and more varied accom- plishments than he had previously met. He could hardly count upon the entire sympathy of Young and Davy, though I believe he remained on friendly terms with them to the end. They were gems of a different water, if I may use the term, from Rumford. The chief object of his fostering care was mechanical invention, as applied to the uses of life. The pleasures of both Young and Davy lay in another sphere. To them science was an end, not a means to an end. The get- ting at the mind of Nature, and the revealing of that mind in great theories, were the objects of their efforts, and formed the occupation of their lives. Had they been as enthusiastic as Rumford himself in Rumford's own direction, the three united would probably have daunted opposition, and for a somewhat longer time endeavoured to realise Rumford's dream. But differ- ences arose between him and the other Managers. ' It is very clear to me,' writes Dr. Bence Jones to Dr. Ellis, * that Count Rumford fell out with Mr. Bernard and with Sir John Hippesley. The fact was that Rum- ford's idea of workshops and kitchen, industrial school, mechanics' institution, model exhibition, social club- COUNT EUMFOBD. 143 house, and scientific committees to do everything, waa much too big and unworkable for a private body, and was fitted only for an absolute and wealthy Grovern merit.' In 1803 Dr. Bence Jones informs us that difficulties were gathering round the Institution, and it was even proposed to sell it off. Rumford had quitted Londoa and gone to Paris. By Davy's aid, Mr. Bernard and Sir John Hippesley carried on the work, but in a fashion different from that contemplated by Rumford that is to say, 4 without workshops, or mechanics' institute, or kitchen, or model exhibition.' The place of these was taken by experimental and theoretical re- searches, which, instead of dealing with things already achieved, carried the mind into unexplored regions of Nature, forgetful, if not neglectful, whether the dis- coveries made in that region had or had not a bearing on the arts, comforts, or necessities of material life. Eumford and his Institution had to bear the brunt of ridicule, and he felt it ; but men of ready wit have not abstained from exercising it on societies of greater age and higher claims. Shafts of sarcasm without number have been launched at the Royal Society. It is perfectly natural for persons who have little taste for scientific inquiry and less knowledge of the methods of Nature, to feel amused, if not scandalised, by the ap- parently insignificant subjects which sometimes occupy the scientific mind. They are not aware that in science the most stupendous phenomena often find their suggestion and interpretation in the most minute that the smallest laboratory fact is connected by in- dissoluble ties with the grandest operations of Nature. Thus, the iridescences of the common soap-bubble, subjected to scientific analysis, have emerged in the conclusion that stellar space is a plenum filled with a material substance, capable of transmitting motion 144 COUNT RUMFORD. with a rapidity which would girdle the equatorial earth eight times in a second ; while the tremors of this sub- stance, in one form, constitute what we call light, and, in all forms constitute what we call radiant heat. Not seeing this connection between great and small; not discerning that as regards the illustration of physical principles there is no great and no small, the wits, con- sidering the small contemptible, permitted sarcasm to flow. But these things have passed away, otherwise it would not be superfluous to remind this audience, as a case in point, that the splendour which in the form of the electric light now falls upon our squares and thoroughfares, has its germ and ancestry in a spark so feeble as to be scarcely visible when first revealed within the walls of this Institution. It is with reluctance that I take the slightest ex- ception to what my American friends have written regarding Eumford and his achievements. But what they have written induces me to assure them that the scientific men of England are not prone to stinginess in recognising the merits of their fellow-labourers in other lands ; and had Eumford, instead of accom- plishing none of his work in the land of his birth, accomplished the whole of it there, his recognition among us here would not be less hearty than it is now. As things stand, national prejudice, if it existed, might be expected to lean to Eumford's side. But no such prejudice exists, and to write as if it did exist is a mistake. In reference to myself, Dr. Ellis, gently but still reproachfully, makes the following remark : ' Professor Tyndall, in his work on " Heat," has but moderately recognised the claims and merit of Eum- ford, when, after largely quoting from his essay, he adds, " When the history of the dynamical theory of heat is COUNT EUMFORD. 145 written, the man who, in opposition to the scientific belief of his time, could experiment, and reason upon experiment, as did Rumford in the investigation here referred to, cannot be lightly passed over." ' In my opinion, the most dignified and impressive way of dealing with labours like those of Rumford, is to show by simple quotations, well selected, what their merits are. This I did in the book referred to by Dr. Ellis, which was published at least eight years in advance of his. But the expression of my admiration for Rum- ford was not confined to the passage above-quoted, which is taken from the appendix to one of my lec- tures. In that lecture I drew attention to Rumford's labours in the following words : * I have particular pleasure in directing the reader's attention to an ab- stract of Count Rumford's memoir on the generation of heat by friction, contained in the appendix to this lecture. Rumford in this memoir annihilates the mate- rial theory of heat. Nothing more powerful on the subject has since been written.' But I must not go too far, nor suffer myself to dwell with one-sided exclusiveness upon the merits of Rum- ford. The theoretic conceptions with which he dealt were not his conceptions, but had been the property of science long prior to his day. This, I fear, was for- gotten when the following claim for Rumford was made by a writer who has done excellent service in diffusing sound science among the people of the United States : 1 'He was the man who first took the question of the nature of heat out of the domain of metaphysics, where it had been speculated upon since the time of Aristotle, and placed it upon the true basis of physical experi- ment.' The writer of this passage could hardly, when 1 The late Dr. Youman*. 146 COUNT RTJMFOKD. he wrote it, have been acquainted with the experiments and the reasonings of Boyle and Hooke, of Leibnitz and Locke. As regards the nature of heat, these men were quite as far removed from metaphysical subtleties as Eumford himself. They regarded heat as ' a very brisk agitation of the insensible parts of an object which produces in us that sensation from whence we denominate the object hot; so what in our sensation is heat, in the object is nothing but motion.' Locke, from whom I here quote, and who merely expresses the ideas previously enunciated by Boyle and Hooke, gives his reasons for holding this theoretic conception^ ' This,' he says, ' appears by the way heat is produced, for we see that the rubbing of a brass nail upon a board will make it very hot ; and the axle-trees of carts and coaches are often hot, and sometimes to a degree that it sets them on fire, by the rubbing of the naves of the wheels upon them. On the other side, the ut- most degree of cold is the cessation of that motion of the insensible particles which to our touch is heat.' The precision of this statement could not, within its limits, be exceeded at the present day. There is a curious resemblance, moreover, between one of the experiments of Boyle, and the most cele- brated experiment of Rumford. Boyle employed three men, accustomed to the work, to hammer nimbly a piece of iron. They made the metal so hot, that it could not be safely touched. As in the case of Rum- ford, people were looking on at this experiment, and Boyle's people, like those of Rumford, were struck with wonder, to see the sulphur of gunpowder ignited by heat produced without any fire. Hooke is equally clear as regards the nature of heat, and like Rumford himself, but more than a century before him, he com- pares the vibrations of heat with sonorous vibrations. COUNT RUMFORD. 147 That Rumford went beyond these men is not to be denied. It could not be otherwise with a spirit so original and penetrating. But to speak of the space between him and Aristotle as if it were a scientific vacuum is surely a mistake. While in Paris, Rumford made the acquaintance of Madame Lavoisier, a lady of wealth, spirit, and social distinction ; and, it is to be added, a lady of temper. Her illustrious husband had suffered under the guillotine on May 8, 1794; and inheriting his great name, to- gether with a fortune of three million francs, she gathered round her, in her receptions, the most dis tinguished society of Paris. She and Rumford became friends, the friendship afterwards passing into what was thought to be genuine affection. The Elector of Bavaria took great interest in Rumford's projected marriage, and when that consummation came near, settled upon him an annuity of 4,000 florins. Before their mar- riage he was joined by Madame Lavoisier at Munich, whence they made a tour to Switzerland. In a letter to his daughter he thus describes his bride-elect : * I made the acquaintance of this very amiable woman in Paris, who, I believe, would have no objection to having me for a husband, and who in all respects would be a proper match for me. She is a widow without children, never having had any; is about my own age [she was four years younger than Rumford], enjoys good health, is very pleasant in society, has a handsome fortune at her own disposal, enjoys a most re- spectable reputation, keeps a good house, which is frequented by all the first philosophers and men of eminence in 4,he science and literature of the age, or rather of Paris ; and, what is more than all the rest, is goodness itself.' He goes on to describe her a& 148 COUNT KUMFOBD. having been very handsome in her day, * and even no\ at forty-six or forty-eight is not bad-looking.' He describes her as rather embonpoint, with a great deal of vivacity, and as writing incomparably well. Before the marriage could take place he was obliged to obtain from America certificates of his birth, and of the death of his former wife. All preliminaries having been arranged, Count Kumford and Madame Lavoisier were married in Paris, on October 24, 1805. He describes the house in which they lived, Hue d'Anjou, No. 39, as a paradise. ' Eemoved from the noise and bustle of the street, facing full to the south, in the midst of a beautiful garden of more than two acres, well planted with trees and shrubbery. The entrance from the street is through an iron gate by a beautiful winding avenue well planted, and the porter's lodge is by the side of this gate ; a great bell to be rung in case of ceremonious visits.' Long after this event Rumford's daughter commented on it thus: 'It seems there had been an acquaintance between these parties of four years before the marriage. It might be thought a long space of time for perfect ac- quaintance. But, " ah Providence ! thy ways are past finding out." ' In a letter written to his daughter two months after his marriage, he describes their style of living as really magnificent ; his wife as exceedingly fond of company, in the midst of which she makes a splendid figure. She seldom went out, but kept open house to all the great and worthy. He describes their dinners and evening teas, which must have been trying to a man who longed for quiet. He could have borne the din- ners, but the teas and their gossip annoyed him. Instead of living melodious days, his life gradually be- came a discord, and on January 15, 1806, he confides COUNT BUMFOBD. 149 to his daughter, as a family secret, that he is ' not at all sure that two certain persons were not wholly mis- taken in their marriage as to each other's charac- ter.' The denouement hastened ; and on the first anniversary of his marriage he writes thus to his daughter: 'My dear child, This being the first year's anniversary of my marriage, from what I wrote two months after it you will be curious to know how things stand at present. I am sorry to say that experience only serves to confirm me in the belief that in charac- ter and natural propensities Madame de Kumford and myself are totally unlike, and never ought to have thought of marrying. We are, besides, both too in- dependent in our sentiments and habits of life to live peaceably together she having been mistress all her days of her actions, and I, with no less liberty, leading for the most part the life of a bachelor. Very likely she is as much disaffected towards me as I am towards her. Little it matters with me, but I call her a female dragon simply by that gentle name I We have got to the pitch of my insisting on one thing and she on another.' On the second anniversary of his marriage, matters were worse. The quarrels between him and Madame had become more violent and open, and having used the word quarrels to his daughter, he gives the follow- ing sample of them : ' I am almost afraid to tell you the story, my good child, lest in future you should not be good ; lest what I am about relating should set you a bad example, make you passionate, and so on. But I had been made very angry. A large party had been invited I neither liked nor approved of, and invited for the sole purpose of vexing me. Our house being in the centre of the garden, walled around, with iron gates, I put on my hat, walked down to the porter'a 150 COUNT RUMFOBD. lodge, and gave him orders, on his peril, not to let any one in. Besides, I took away the keys. Madame went down, and when the company arrived, she talked with them, she on one side, they on the other, of the high brick wall. After that she goes and pours boiling water on some of my beautiful flowers.' Six months later, the sounds of lamentation and woe are continued. There was no alteration for the better. He thought of separation, but the house and garden in the Rue d'Anjou being a joint concern, legal difficulties arose as to the division of it. ' I have suf- fered,' he says to his daughter, * more than you can imagine for the last four weeks; but my rights are incontestable, and I am determined to maintain them. I have the misfortune to be married to one of the most imperious, tyrannical, unfeeling women that ever existed, and whose perseverance in pursuing an object is equal to her profound cunning and wickedness in framing it.' He purposed taking a house at Auteuil. It would be unfortunate if, notwithstanding all the bounties of the King of Bavaria, he could not live more independently than with this unfeeling, cunning, tyrannical woman. ' Alas ! little do we know people at first sight ! Do you preserve my letters ? You will perceive that I have given very different accounts of this woman, for lady I cannot call her.' He describes his habitation as no longer the abode of peace. He breakfasts alone in his apartment, while to his infinite chagrin most of the visitors are his wife's determined adherents. He is sometimes present at her tea-parties, but finds little to amuse him. 'I have waited,' he says (which we may doubt), ' with great, I may say unexampled patience, for a return of reason and a change of conduct, but I am firmly resolved not to be driven from my ground, not even by disgust. A sepa- COUNT BUMFORD. 151 ration,' he adds, * is unavoidable, for it would be highly improper for me to continue with a person who has given me so many proofs of her implacable hatred and malice.' The lease of the villa at Auteuil was purchased by Rumford in 1808. The separation between him and his wife took place * amicably' on the 13th of June* 1809. Ever afterwards, however, anger rankled in his heart. He never mentions his wife but in terms of repugnance and condemnation. His release from her fills him with unnatural jubilation. On the fourth anni- versary of his wedding-day he writes to his daughter : ' I make choice of this day to write to you, in reality to testify joy, but joy that I am away from her.' On the fifth anniversary he writesthus : * You will perceive that this is the anniversary of my marriage. I am happy to call it to mind that I may compare my present situation with the three and a half horrible years I was living with that tyrannical, avaricious, unfeeling woman.' The closing six months of his married life he describes as a purgatory sufficiently painful to do away with the sins of a thousand years. Rumford, in fact, writes with the bitterness of a defeated man. His wife retained her friends, while he, who a short time pre- viously had been the observed of all observers, found himself practically isolated. This was a new and bitter experience, the thought of which, pressing on him con- tinually, destroyed all magnanimity in his references to her. From 1772 to 1800, Rumford's house at Auteuil had been the residence of the widow of a man highly celebrated in his day as a freethinker, but whom Lange describes as ' the vain and superficial Helvetius.' It is also the house in which, in the month of January 1870, the young journalist Victor Noir was shot dead by Prince 152 COUNT EUMFORD. Pierre Bonaparte. Here, towards the end of 1811, the Count was joined by his daughter. They found pleasure in each other's company, but the affection between them does not appear to have been intense. In his conversa- tions with her the source of his bitterness appears. * I have not,' he says, * deserved to have so many enemies ; but it is all from coming into France, and forming this horrible connection. I believe that woman was born to be the torment of my life.' The house and gardens were beautiful ; tufted woods, winding paths, grapes in abund- ance, and fifty kinds of roses. Notwithstanding his hostility to his wife, he permitted her to visit him on apparently amicable terms. The daughter paints her character as admirable, ascribing their differences to individual independence arising from having been accus- tomed to rule in their respective ways : * It was a fine match, could they but have agreed.' One day in driving out with her father, she remarked to him how odd it was that he and his wife could not get on together, when they seemed so friendly to each other, adding that it struck her that Madame de Eumford could not be in her right mind. He replied bitterly, 'Her mind is, as it has ever been, to act differently from what she appears.' The statesman Gruizot was one of Madame de Kumford's most intimate friends, and his account of her and her house is certainly calculated to modify the account of both given by her husband. Kumford became her guest at a time when he enjoyed in public 'a splendid scientific popularity. His spirit was lofty, his conversa- tion was full of interest, and his manners were marked by gentle kindness. He made himself agreeable to Madame Lavoisier. He accorded with her habits, her tastes, one might almost say with her reminiscences, COUNT RUMFORD. 153 .... She married him, happy to offer to a dis- tinguished man a great fortune and a most agreeable existence.' Guizot, who writes thus, goes on to state that their characters and temperaments were incom- patible. They had both grown to maturity accustomed to independence, which it is not always easy even for tender affection to stifle. The lady had stipulated, on her second marriage, that she should be permitted to retain the name of Lavoisier, calling herself Madame Lavoisier de Rumford. This proved disagreeable to the Count, but she was not to be moved from her de- termination to retain the name. ' I have,' she says, * at the bottom of my heart a profound conviction that M. de Rumford will not disapprove of me for it, and that on taking time for reflection, he will permit me to continue to fulfil a duty which I regard as sacred.' Guizot adds that the hope proved deceptive, and that ' after some domestic agitations, which M. de Rumford, with more of tact, might have kept from becoming so notorious, a separation became necessary.' Guizot describes her dinners and receptions during the re- maining twenty-seven years of her life as delightful. Cultivated intellects, piquant and serious conversation, excellent music, freedom of mind and tongue, without personal antagonism or political bias, ' license of thought and speech without any distrust or disquiet as to what Authority might judge or say a privilege then more precious than any one to-day imagines, just as one who has breathed under an air-pump can best appreciate the delight of free respiration.' One cannot, however, forget the pouring of boiling water over the * beautiful flowers.' The * Gentleman's Magazine ' for 1814 describes the collision in which Rumford's later days were spent. 154 COUNT RUMFORD. After the death of the illustrious Lagrange, he saw but two or three friends, nor did he attend the meetings of the National Institute, of which he was a member. Cuvier was then its perpetual secretary, and for him Rumford entertained the highest esteem. He differed from Laplace on the question of * surface-tension,' and dissent from a man then standing so high in the mathe- matical world was probably not without its penal con- sequences. Rumford always congratulated himself on having brought forward two such celebrated men as the Bavarian general Wieden, who was originally a lawyer or land steward, and Sir Humphry Davy. The German, French, Spanish, and Italian languages were as familiar to the Count as English. He played billiards against himself; he was fond of chess, which however made his feet like ice and his head like fire. The designs of his inventions were drawn by himself with great skill ; but hfe had no knowledge of painting and sculpture, and but little feeling for them. He had no taste for poetry, but great taste for landscape-gardening. In later life his habits wer most abstemious, and it is said that his strength was in this way so reduced as to render him unable to resist his last illness. After three days' suf- fering from nervous fever he succumbed on August 21, 1814, when he was on the eve of returning to England. He was buried in the small cemetery of Auteuil, which has since been disused as a place of burial. The grave, says Dr. Ellis, is marked by a horizontal stone une pierre tumulaire and by a perpendicular monument 6 feet high, 6 feet in breadth, and 3 feet in thickness. Both are of marble, and bear inscriptions as follows. That on the monument is : COUNT RUMFORD. 155 A la Memoire de BENJAMIN THOMPSOH, Comte de Rumford, n6 en 1753, & Concord ' pres Boston, en Amerique, mort le 21 Aout, 1814, & AuteuiL Physicien c61bre, Philanthrope clair6, ses decouver'.es sur la lumiere et la chaleur ont illnstre son nom.

KUMFORD'S SCIENTIFIC WORK. As a factor in human affairs, Rumford ascribed to gunpowder a dominant importance. No other invention had exercised so great an influence. Hence the arduous labour he expended in determining its action. At Stoneland Lodge, the country seat of Lord George Germain, in the year 1778, his inquiries into the force and applications of gunpowder began. He directed his attention to the position of the vent, the weight and pressure of the charge, its bursting power, the quickness of combustion, the weight and velocity of the projectile, the effect of windage, and to many other matters of in- terest to the gunner. On all these questions he threw 1 Ought to be Woburn. 11 156 COUNT RUMFORD. important light. The velocity was determined in two ways: first, by the ballistic pendulum, invented by his predecessor and namesake, Benjamin Robins ; and secondly, from the recoil of the gun itself. The ballistic pendulum is a heavy mass, so suspended as to be capable of free oscillation. Against it the bullet is projected, and from the weight of the bullet, the weight of the pendulum, and the arc, or distance, through which it is urged by the bullet, the velocity of the latter may be calculated. To determine the recoil of the gun, he had it sus- pended by a bifilar arrangement, which permitted it to swing back when it was fired. Action and reaction being equal, the momentum of the gun was the momentum of the bullet on leaving the gun, and from the weight of the piece, and the arc of recoil, the velocity of the bullet was computed. The agreement between the results obtained by these two methods was in many cases re- markable. Until quite recently, Rumford's experiments on the force of gunpowder were considered to be the best extant. A mind so observant could not fail to notice the heating effects produced by the percussion of the bullet against its target, and by the jar of the gun at the moment of its discharge. By such facts he was naturally led to reflect on that connection between mechanical power and heat which he afterwards did so much to illustrate and develop. The phenomena both of light and heat fascinated him ; and we accordingly find him from time to time abandoning practical aims, and seeking for knowledge which had no apparent practical outcome. Thus we see him experimenting on the action of green vegetables and other matters upon light, or rather the action of light on the green leaves of plants. From this inquiry he turned to estimate the quantities of moisture taken COUNT BUMFORD. 157 up by different substances in humid air. Sheep's wool he found to be the most absorbent, while cotton wool and ravellings of fine linen were among the least. These experiments he regarded as of the highest importance, as they explained, to his mind, the salubrity of flannel when worn next the skin. Its healthfulness he ascribed to its power of taking up the moisture of the body, sensible and insensible, and dispersing it by evaporation in the air. The propagation of heat in fluids was but imperfectly understood when Rumford took the subject up. In various parts of his writings he dwells on the importance of what he calls accidental observations, deeming them more fruitful than those which have sprung from the more recondite thoughts of the philosopher. But acci- dents, however numerous, if they fail to reach the proper soil are barren. Kumford ascribed to accident the investigations now referred to. He had been experi- menting upon liquids, employing bulbs of copper with glass tubes attached to them. On one occasion, having filled his bulb and tube with spirits of wine, and heated the liquid, he placed it to cool in a window where the sun happened to shine upon it. Particles of dust had found their way into the spirit, and the sun, shining on these particles, made their motions vividly apparent. Along the axis of his tube the illuminated particles rose ; along its sides they fell, thus making manifest the currents within the liquid. The reason of this circula- tion is obvious enough. The glass tube in contact with the cold air had its temperature lowered. The glass drew heat from the liquid in contact with it, which thereby being rendered more dense, fell along the sides of the tube, while, to supply its place, the lighter liquid rose along the axis. The motion here described is 158 COUNT EUMi'ORD. exactly that of the great geyser of Iceland. The water falls along the sides of the geyser tube, and rises along the axis. In this way, then, heat is propagated through liquids. It is a case of bodily transport by currents, and not one of true conduction from molecule to molecule. It immediately occurred to Rumford to hamper this motion of convection. He called to mind an observation he had made at Baiae, where the water of the sea being cool to the touch, the sand a few inches below the water was intolerably hot. This he ascribed to the impedi- ment offered by the sand to the upward diffusion of the heat. The length of time required by stewed apples to cool also occurred to him. He had frequently burnt his mouth by a spoonful of apple taken from the centre of a dish after the surface had become cool. He devised thermometers with a view of bringing his notions to an experimental test. With pure water he compared water slightly thickened with starch, water containing eider- down, and stewed apples bruised into a pulp which con- sisted almost wholly of water. In all cases he found the propagation of heat impeded, and cooling retarded, by everything that prevented the formation of currents. As he pursued his inquiries, the idea became more and more fixed in his mind that convection is the only means by which heat is diffused in liquids. He denied them all power of true conduction, and though his ex- periments did not, and could not prove this, they did prove that in the propagation of heat through the liquids he examined, which were water, oil, and mercury, conduction played an extremely subordinate part. Rumford changes from time to time the tone of the philosopher for that of the preacher. He seems filled with religious enthusiasm on contemplating what he holds to be the wisdom and benevolence displayed in the arrangement of the physical world. One fact in COUNT RUMFOBD. 159 particular excited this emotion. De Luc had pointed out that when water is cooled, it shrinks in volume, until it reaches a temperature of about 40 Fahr. At this point it ceases to contract, and expands when cooled still fur- ther. The expansion we now know to be due to incipi- ent crystallisation, or freezing, which, when it once sets in, greatly, and suddenly, enhances the expansion. A con- sequence of this is that ice floats as a lighter body upon water. This fact riveted the attention of Eumford, and its obvious consequences filled him with the enthusiasm to which I have referred. He was strong, but untrained, and his language was not always such as a truly dis- ciplined man of science would employ. ' Let me,' he says, * beg the attention of my reader, while I endeavour to investigate this most interesting subject, and let me at the same time bespeak his candour and indulgence. I feel the danger to which a mortal exposes himself who has the temerity to undertake to explain the designs of Infinite Wisdom. The enterprise is adventurous, but it cannot surely be improper.' He 4 explains ' accordingly ; and notwithstanding his professed humility, does not hesitate to brand those who fail to see with his eyes as degraded, and quite callous to every ingenuous and noble sentiment.' He indulges in excursions of the imagination to show the misfortunes that would accrue if the arrangement of the world had been different from what it is. ' Had not Providence, in a manner which may be well considered as miraculous,' stopped the contraction of water before it reached its freezing point, and caused it to expand afterwards, a single winter would freeze every fresh-water lake within the polar circle to a vast depth, ' and it is more than probable that the regions of eternal frost would have spread on every side from the poles, and, advancing towards the equator, would have extended its dreary 160 COUNT BUMFORD. and solitary reign over a great part of what are now the most fertile and most inhabited climates of the world I ' He expands this thesis in various directions, the whole argument being based on the assumption that ' all bodies are condensed by cold, without limitation, WATER ONLY EXCEPTED.' Repeated disappointments in such matters have taught us caution. Legitimate grounds for wonder exist everywhere around us; but wonder must not be cultivated at the expense of truth. Brought to the proper test, the assumption on which Rumford built his striking teleological argument is found to be a mere quicksand. The fact he adduces as unique is not an exception to a universal law. There are other substances, to which his reasoning has not the remotest application, which, like water, expand before and during crystallisation. The condi- tions necessary to the life of our planet must have ex- isted before life appeared ; but whether those conditions had prospective reference to life, or whether its im- manent energy did not seize upon conditions which grew into being without any reference to life, we do not know ; and it would be mere arrogance at the present day to dogmatise upon the subject. In the controversy whether heat was a form of matter or a form of motion, Rumford espoused the latter view. Now those who supposed heat to be matter naturally thought that it might be ponderable, and ex- periments favourable to this notion had been executed. Operating with a balance of extreme delicacy, Rumford took up this question, and treated it with great skill and caution. His conclusion from his experiments was that, if heat be a substance a fluid sui generis it must be something so infinitely rare, even in its condensed state, as to baffle all our attempts to discover its gravity, COUNT RUMFOUD. 161 But ' if the opinion which has been adopted by many of our ablest philosophers, that heat is an intestine vibra- tory motion of the constituent parts of bodies, should be well founded, it is clear that the weights of bodies can be in no wise affected by such motion.' The weight of a bell, he urges in another place, is not affected by its sonorous vibration. Early in the year 1803, he being then in Munich, Eumford broke ground in the domain of radiant heat. He prepared bright metallic vessels, filled them with hot water, placed them in a large and quiet room, and observed the time required to cool them down a certain number of degrees. Covering some of his vessels with Irish linen and leaving others bare, he found, to his surprise, that the covered vessels were more rapidly chilled than the naked ones. Comparing in the same room a thick glass bottle, filled with hot water, with a tin bottle of the same shape and size, he found that the water in the glass vessel cooled twice as rapidly as that in the tin one. When, moreover, he coated his metallic vessel with glue, the cooling process was hastened, as it had been by the linen. Applying a second, a third, and a fourth coating of glue, he found the chilling pro- moted. Here, however, he came to a point where the addition of any further coatings produced a retardation of the chilling. Painting some of his vessels black and some white, he found the times of cooling to be practi- cally the same for both a result which he seems to have afterwards forgotten. From these and other ex- periments of the same kind he drew the just conclusion that a hot body does not lose its heat by the mere com- munication of it to the air, but that a large proportion of the heat escapes in rays, the escape being facilitated by the substances with which his vessels were coated, 162 COUNT EUMFOBD. The more rapid chilling of the glass bottle was due, in like manner, to the fact that glass possesses a greater radiative power than tin. He next applies himself with energy, zeal, and tenacity to prove that there are frigorific rays which act in all respects like calorific rays, and which enjoy an individuality quite as assured as that of the latter. Pfe pictures his frigorific rays as produced by vibrations of a special kind. In Pictet's celebrated experiment of conjugate mirrors, and in many other experiments, chilling by a cold body showed itself to be so exactly analogous to heating by a warm one, that Eumford never could shake from his mind the notion of rays of cold. The fall of the thermometer in one focus when a lump of ice was placed in the other, was in his view caused by a positive emission of cold rays from the ice, and not by its absorption of the heat radiated against it by the thermometer. These frigorific rays, he says, were suspected by Bacon. Their existence was actually established by the academicians of Florence, but these learned gentlemen were so l blinded by their prejudices respecting the nature of heat, that they did not believe the report of their own eyes.' Kumford indulges in various untenable speculations and erroneous notions regarding the part played by clothing, by the blackness of the negro's skin, and by the oiled surface of the Hottentot. We are, he con- tends, kept warm by our clothing, not so much by con- fining our heat as by keeping off the frigorific rays which tend to cool us. He reverts to the respective cases of a black and a white man, and describes an ex- periment which elucidates his views. He covered two of his vessels with goldbeater's skin, and painted one of them black with Indian ink, leaving the other of its natural while colour. Filling both vessels with hot COUNT RUMFORD. 163 water, he left them to cool in the air of a large, quiet room. The vessel covered with the black skin repre- sented a negro, the other vessel a white man ; and the re- Bult was that while the black required only 23 minutes to cool, the white man required 28 minutes. The prac- tical issue of the experiment is thus stated : "All I will venture to say on the subject is, that were I called to inhabit a very hot country, nothing should prevent me from making the experiment of blackening my skin, or at least of wearing a black shirt, in the shade, and espe- cially at night, in order to find out if, by those means, I could not contrive to make myself more comfortable.' There was at times a headstrong element, if I may use the term, in Rumford's scientific reasoning. He here overlooks the fact that in a former experiment he found scarcely an appreciable difference between white and black as regards their powers of cooling. He also forgets the possible influence of a second coating, which his former experiments had revealed. As regards the negro and the white man, Rumford's first experiment illustrated the case more correctly than his subsequent ones. There are, moreover, transparent substances which, used as varnishes, would not have impaired the whiteness of the goldbeater's skin, but which would have hastened the cooling even more than the Indian ink. Those who are acquainted with Sir John Leslie's experiments on radiant heat will not fail to notice that he and Rumford travelled over common ground. With a view of setting this matter right Rumford wrote a paper entitled ' Historical Review of Experiments on the Subject of Heat,' in which he shows that his experi- ments were not only talked about and executed before learned societies, but that they were in part published prior to the appearance of Leslie's celebrated work in 1804. Still, the style of that work furnishes, I think, 164 COUNT RUMFORD. internal evidence of its perfectly independent character, while the extent and variety of Leslie's labours render it practically impossible that they could have been de- rived from anything that Rumford had previously done. The two philosophers had no personal knowledge oi each other, and the credit to be awarded, where the-}' deal with the same subject, belongs, I think, equally to both. Rumford's experimental work was far smaller in quantity than that of Leslie, but in regard to theory he must be conceded the highest place. In theory Leslie was inconsistent and confused, while Kumford, judged by the circumstances of his time, was in the main clear and correct. The part played by the luminiferous ether in the phenomena of light had been revived and enforced by the powerful experiments of Dr. Thomas Young. The undulatory hypothesis was therefore at hand, and Rumford made ample use of it. He has written a paper entitled ' Reflections on Heat,' in which he describes the views regarding its nature that were prevalent in his time. * Some,' he says, ' regard it as a substance, of/hers as a vibratwy motion of the particles of matter of which a body is composed.' The heating of a body is, on the one hypothesis, due to the accumulation within it of caloric, while others hold the heating to be due to the acceleration of the vibratory motion. ' On the hypothesis of vibratory motion, a body which has become cold is thought to have lost nothing except motion ; on the other hypothesis, it is supposed to have lost some material substance.' The loss of motion Rumford clearly apprehends to be due to its communica- tion to ' an eminently elastic fluid au ether which fills all space throughout the universe.' The theoretic notions thus expressed are, in point of clearness and correct- ness, iar in advance of those entertained by Leslie. COUNT RUMFOJBD. 165 As already mentioned, the fact of water changing its density at a temperature of 40 Fahr. powerfully affected the mind of Rumford. On this subject he made many experiments; and one of the minor applica- tions of the knowledge thus derived may be here noted. In company with his friend Professor Pictet, of Geneva, he paid a visit to the Mer de Glace, and discovered in the ice a pit * perfectly cylindrical, about seven inches in diameter, and more than four feet deep, quite full of water.' He was informed by his guides that these pits are formed in summer, and gradually increase in depth during the warm weather. How can these pits deepen ? Rumford answers thus : The warm winds which in summer blow over the surface of the column of ice-cold water, communicate some small degree of heat to the fluid. The water at the surface being thus rendered specifically heavier, sinks to the bottom of the pit, to which the heat thus carried down is communicated, melting the ice and increasing the depth of the pit. We have here a small specimen of Rumford's penetration, but it is a very interesting one. The sun's invisible rays, however, are probably more influential than the action of the warm wind in producing the observed effect. Various interesting experiments were made by Rumford on what is now known as 'surface-tension.' From his experiments he inferred that the surface of a liquid of water, for example is covered by a pellicle which can be caused to tremble throughout by touching it with the point of a needle. He proposed to the geometricians of Paris to determine the shape of a drop resting on a horizontal surface, and restrained solely by the resistance of a pellicle exerting a given force on its surface. This pellicle he considers to be due to the adhesion of the particles of liquids to each other, and he 166 COUNT KUMFORD. makes various ingenious calculations to determine the size of a particle of heavy matter of gold, for instance which would rest suspended in water because of its inability to force asunder the particles of the liquid. The diameter of a sphere of gold which would behave in this way he found to be YS^TTTF f an i ncn Even among scientific men, probably few are aware that Rumford experimented on the diffusion of liquids ; a field of investigation in which Graham afterwards rendered himself so eminent. Into a glass cylinder, If inch in diameter and 8 inches high, he poured a layer of saturated aqueous solution of muriate of soda 3 inches thick ; over this he carefully poured a layer of distilled water of the same thickness ; he then let a drop of the oil of cloves fall into the vessel. This oil, being heavier than the pure water and lighter than the solution, rested as a sphere at the common boundary of the two liquids. A layer of olive oil four lines in thickness was then poured over the water, in order to shut off the air. The object of the experiment was to ascertain whether one liquid remained permanently superposed upon the other without any mixing. If this proved to be the case, the position of the drop of oil would remain con- stant; but if the heavy mineial solution rose into the water overhead, the drop of oil, which Eumford called his 'little sentinel,' would warn him of the event by rising in the liquid. After twenty-four hours he entered the cellar in which the experiment was made, and found that the little ball of oil had risen three lines. For six days it continued to rise at the rate of about three lines a day. He afterwards expe- rimented with other solutions, the result being ' that the mixture went on continually, but very slowly, be- tween the various aqueous solutions employed and the distilled water resting upon them.' Kumford's experi- COUNT RUMFOED. 167 inents were probably prompted by his views on mole- cular physics. He would hardly have thought of the foregoing arrangement were not the intestine motions of the ultimate particles of bodies present to his mind. He was, moreover, quite aware of the importance of the result here established. The subject had often occupied his thoughts, and he had at different times made ' a considerable number of experiments with a view ol throwing light into the profound darkness with which the subject is shrouded on every side.' He devoted his attention to steam, considered as a vehicle for transporting heat ; he sought for the means of increasing the heat obtained from fuel ; he devised a new steam-boiler, in which we have a forecast of the tubular boiler of George Stephenson. After some preliminary experiments on wood and charcoal, he definitely took up the important investigation of the quantity of heat developed in combustion, and in the condensation of vapours. He described the new calori- meter employed in the inquiry. It was a kind of worm through which the heated air and products of combus tion were led, and in which the heat was delivered up to cold water surrounding the worm. He experimented upon white wax, spirit of wine, alcohol, sulphuric ether, naphtha, charcoal, wood, and inflammable gases. Whenever it was possible he aimed at quantitative results, and in the present instance he * estimated the calorific power of a body by the number of parts by weight, of water, which one part by weight of the body would, on perfect combustion, raise one degree in temperature. Thus 1 Ib. of charcoal, in com- bining with 2 Ibs. of oxygen, to form carbonic acid, evolves heat sufficient to raise the temperature of about 8,000 Ibs. of water 1 C. Similarly, 1 Ib. of hydrogen, in combining with 8 Ibs. of oxygen, to form water, 168 COUNT RUMFORD. generates an amount of heat sufficient to raise 34,000 Ibs. of water 1 C. The calorific powers, therefore, of carbon and hydrogen are as 8 : 34. The refined re- searches of Favre and Silbermann entirely confirm these determinations of Eumford ' (Percy). Follow- ing the experiments on combustion, we have others made to determine the quantity of heat set free by the condensation of various vapours, and the capacity of various liquids for heat. We have also an elaborate inquiry into the structure of wood, the specific gravity of its solid parts, the liquids and elastic fluids contained in it, the quantity of charcoal to be obtained from it, and the heat generated by the combustion of wood of different kinds. But the main object of Rumford's life and the sub- ject which chiefly interested him was the practical management of fire, and the economy of fuel. Eighty- seven pages of the second volume of his collected works are devoted to this subject. The whole of the third volume is devoted to it, while a large portion of the fourth and last volume is occupied with kindred ques- tions. Some of those essays are rather tiresome to a reader of the present day, and Rumford had a suspicion that they might appear so to contemporary readers. * I believe,' he says, ' that I am sometimes too prolix for the taste of the age ; but it should be remembered that the subjects I have undertaken to investigate are by no means indifferent to me ; that I conceive them to be intimately connected with the comforts and enjoy- ments of mankind ; and that a habit of revolving them in my mind, and reflecting on their extensive usefulness, ha^ awakened my enthusiasm, and rendered it quite impossible for me to treat them with cold indifference.' For the most part, it is only when Rumford is self- COUNT KUMFORD. 169 conscious that this tedium appears. He wishes to ex- cite his reader's interest, and sometimes adopts means to this end which defeat themselves. Such is the case when he dwells with reiteration on the refined and ex- quisite pleasure which he derives from being of service to humanity. Some also would deem him tedious, though I deem him courageous, when he deals with the details of his schemes. He leaves no stone unturned in his effort to render himself clear. He is in many cases simply writing out a specification, to be followed in all particulars. He gives directions as to the manner in which a slice of hasty pudding is to be eaten. A small pit is to be dug in the centre of the cake, a piece of butter placed in the pit, while the removed bit is to be placed on the butter to aid in melting it. You then begin at the circumference of your pudding, and eat all round, dipping each piece in the butter before convey- ing it to the mouth. Such details were sure to provoke sarcasm, and they did provoke it. But amid the verbosity we have incessant flashes of practical wisdom and ex- amples of intellectual force. When he ceases to think of the exquisite delight of his philanthropic labours ceases to think of himself and permits his own per- sonality to be effaced by his subject, we see Kumford at his best ; and his best was excellent. Suggestion fol- lows suggestion, experiment succeeds experiment, until he has finally exhausted his subject, or is pulled up by inability to proceed further. He tested quantitatively the relative intensities of various lights, constructing, while doing so, his well- known photometer. Placing two lights in front of a white screen, and at the same distance from it, and fixing an opaque rod between the lights and the screen, he obtained two shadows corresponding to the two 170 COUNT EUMFOKD. lights. When the lights were equally intense, the shadows were equally dark, but when one of the lights was more powerful than the other, the shadow corre- sponding to that other was rendered pale, because the light from the most intense source fell upon it. Ee- moving the more intense light farther from the screen, until a point was reached when the shadows appeared equal, Rumford obtained all the elements necessary for the computation of the relative intensities of the lights. He had only to apply the law of inverse squares, which makes a double distance correspond to a fourfold in- tensity, a treble distance to a ninefold intensity, and so on. In connection with these experiments he dwells repeatedly upon a defect which harasses the official gas- examiners of the present day, and that is, the fluctua- tions of the candles used as standards of measurement. These photometric measurements are succeeded by a brief but beautiful essay on * Coloured Shadows,' which, in connection with another short essay on the < Harmony of Colours,' strikingly illustrates Rumford's penetration and experimental skill. He produced two shadows, one from day light, the other from candle-light. The daylight shadow being shone upon by the candle, was, as might be expected, yellow, because the candle sheds a yellow light. But the other shadow, instead of being colour- less, was ' the most beautiful blue that it was possible to imagine.' He states clearly that the colour of one shadow is real, while that of the other is imaginary. He finds it * impossible to produce two shadows at the same time from the same body, the one answering to a beam of daylight, and the other to the light of a candle or lamp, without these shadows being coloured, the one yellow, and the other blue.' He obtained shadows from a light coloured by means of interposed glasses, and compared them with shadows obtained from un- COUNT KUMFORD. 171 coloured light. The shadows were always coloured when the lights differed from each other in whiteness, and the colours of the shadows were always such as, when added together, produced a pure white. The real colour, in fact, evoked, or ' called up,' or summoned an imaginary complementary colour. Goethe probably derived the expression ' geforderte Farben,' which occurs BO often in the ' Farbenlehre,' from the terminology of Jiumford. But the experiments and discussion on which the fame of Rumford mainly rests are described in an essay of twenty pages a vanishing quantity when compared with the sum-total ot his published work. A cannon foundry had been built under his superintendence at Munich, where the heat developed during the boring of cannon powerfully attracted his attention. Upon this heat he made numerous tentative experiments, which are described in the essay. With the view of determin- ing its exact quantity, he cut a cylinder from the muzzle end of a gun not yet bored, partially hollowed out this cylinder, and fitted into it a borer which resembled a blunt chisel in shape. The borer being strongly pressed against the bottom of the cylinder, it was caused to ro- tate by horse-power. He surrounded his cylinder with a wooden box, filling the box with water which embraced the entire cylinder. Soon after the starting of the rota- tion, the water felt warm to the hand. In an hour it had risen to 107 in temperature. In two hours and twenty minutes it had risen to 200, while in two hours and thirty minutes it actually boiled. * Rumford carefully estimated the quantity of heat possessed by each portion of his apparatus at the con- elusion of his experiment, and adding all together, found a total sufficient to raise 26'58 Ibs. of ice-cold 12 172 COUNT RUMFOKD. water to its boiling-point, or through 180 Fahr. By careful calculation he found this heat equal to that given out by the combustion of 2303'8 grains ( = 4-^ oz. troy) of wax. He then determined the " celerity " with which the heat was generated, summing up thus : " From the results of these computations it appears that the quantity of heat produced equably, or in a con- tinuous stream, if I may use the expression, by the friction of the blunt steel borer against the bottom of \be hollow metallic cylinder, was greater than that pro- duced in the combustion of nine wax candles, each three-quarters of an inch in diameter, all burning together with clear bright flames." '"One horse," he continues, "would have been equal to the work performed, though two were actually employed. Heat may thus be produced merely by the strength of a horse, and in a case of necessity, this heat might be used in cooking victuals. But no cir- cumstances could be imagined in which this method of procuring heat would be advantageous ; for more heat might be obtained by using the fodder necessary for the support of a horse as fuel." ' This is an extremely igni6cant passage, intimating, as it does, that Kumford saw clearly that the force of animals was derived from the food, no creation of force taking place in the animal body. * By meditating on the results of all these experi- ments, we are naturally,' he says, ' brought to the great question which has so often been the subject of "specu- lation among philosophers, namely, What is heat is there any such thing as an igneous fluid ? Is there anything that, with propriety, can be called caloric?' ' We have seen that a very considerable quantity of heat may be excited by the friction of two metallic surfaces, and given off in a constant stream or flux in COUNT BUMFOBD. 173 all directions, without interruption or intermission, and without any signs of diminution or exhaustion. In reasoning on this subject, we must not forget that most remarkable circumstance, that the source of the heat generated by friction in these experiments appeared evidently to be inexhaustible. It is hardly necessary to add that anything which any insulated body or system of bodies can continue to furnish without limi- tation cannot possibly be a material substance ; and it appears to me to be extremely difficult, if not quite impossible, to form any distinct idea of anything capa- ble of being excited and communicated in those expe- riments, except it be Motion.' ' 1 Heat a Mode of Motion, Lecture II. 1884. LOUIS PASTEUR, HIS LIFE AND LABOURS. (A Eeview.) ' IN the early part of the present year the French original of this work was sent to me from Paris by its author. It was accompanied by a letter from M. Pasteur, expressing his desire to have the work translated and published in England. Eesponding to this desire, I placed the book in the hands of Messrs. Longman, who, in the exercise of their own judgment, decided on publication. The translation was confided, at my suggestion, to Lady Claud Hamilton. The translator's task was not always an easy one, but it has, I think, been well executed. A few slight abbreviations, for which I am responsible, have been introduced, but in no case do they affect the sense. It was, moreover, found difficult to render into suitable English the title of the original : ' M. Pasteur, His- toire d'un Savant par un Ignorant.' A less piquant and antithetical English title was therefore substituted for the French one. This filial tribute, for such it is, was written, under the immediate supervision of M. Pasteur, by his devoted and admiring son-in-law, M. Valery Eadot. Tt is the record of a life of extraordinary scientific ardour and success, the picture of a mind on which facts fall like germs upon a nutritive soil, and, like germs so 1 Written as an introduction to the Ensrlish translation. LOUIS PASTEUR, HIS LIFE AND LABOURS. 175 favoured, undergo rapid increase and multiplication. One hardly knows which to admire most the intuitive vision which discerns in advance the new issues to which existing data point, or the skill in device, the adaptation of means to ends, whereby the intuition ia brought to the test and ordeal of experiment. In the investigation of microscopic organisms the * infinitely little,' as Pouchet loved to call them and their doings in this our world, M. Pasteur has found his true vocation. In this broad field it has been his good fortune to alight upon a crowd of connected problems of the highest public and scientific interest, ripe for solution, and requiring for their successful treatment the precise culture and capacities which he has brought to bear upon them. He may regret his abandonment of molecular physics ; he may look fondly back upon the hopes with which his researches on the taitrates and paratartrates inspired him ; he may think that great things awaited him had he continued to labour in this line. I do not doubt it. But this does not shake my conviction that he yielded to the natural affinities of his intellect, that he obeyed its truest impulses, and reaped its richest rewards, in pursuing the line that he has chosen, and in which his labours have rendered him one of the most conspicuous scientific figures of this age. With regard to the earliest labours of M. Pasteur, a few remarks supplementary to those of M. Kadot may be introduced here. The days when angels whispered into the hearkening human ear secrets which had no root in man's previous knowledge or experience are gone for ever. The only revelation and surely it deserves the name now open to the wise arises from ' intending the mind ' on acquired know- ledge. When, therefore, M. Radot, following M. Pas- 176 LOUIS PASTEUR, teur, speaks with such emphasis about 'preconceived ideas,' he cannot mean ideas without antecedents. Preconceived ideas if out of deference to M. Pasteur the term be admitted are the vintage of garnered facts. We in England should rather call them induc- tions which, as M. Pasteur truly says, inspire the mind and shape its course in the subsequent work of deduc- tion and verification. At the time when M. Pasteur undertook his inves- tigation of the diseases of silkworms, which led to such admirable results, he had never seen a silkworm ; but so far from this being considered a disqualifica- tion, his friend M. Dumas regarded his freedom as a positive advantage. His first care was to make him- self acquainted with what others had done. To their observations he added his own, and then, surveying all, came to the conclusion that the origin of the disease was to be sought, not in the worms, not in the eggs, but in the moths which laid the eggs. I am not sure that this conclusion is happily described as *a preconceived idea.' Every whipster may have his preconceived ideas ; but the divine power, so largely shared by M. Pasteur, of drilling from facts their essences of extracting from them the principles from which they flow is given only to a few. With regard to the discovery of crystalline facets in the tartrates, dwelt upon by M. Radot, a brief reference to antecedent labours may be, here allowed. It had been discovered by Arago, in 1811, and by Biot, in 1812 and 1818, that a plate of rock-crystal, cut perpendicular to the axis of the prism, and crossing a beam of plane polarised light, caused the plane of polarisation to rotate through an angle, dependent on the thickness of the plate and the refrangibility of the light. It had, HIS LIFE AND LABOUES. 177 moreover, been proved by Biot that there existed two species of rock-crystal, one of which turned the plane of polarisation to the right, and the other to the left. They were called respectively, right-handed and left- handed crystals. No external difference of crystalline form was at first noticed which could furnish a clue to this difference of action. But closer scrutiny revealed upon the crystals minute facets, which, in the one class, were ranged along a right-handed, and, in the other, along a left-handed spiral. The symmetry of the hexagonal prism, and of the two terminal pyramids of the crystal, was disturbed by the introduction of these spirally-arranged facets. They constituted the outward and visible sign of that inward and invisible molecular structure which produced the observed action, and difference of action, on polarised light. When, therefore, the celebrated Mitscherlich brought forward his tartrates and .paratartrates of ammonia and Boda, and affirmed them to possess the same atoms, the same internal arrangement of atoms, and the same out- ward crystalline form, one of them, nevertheless, causing the plane of polarisation to rotate, while the other did not, Pasteur, remembering no doubt the observations just described, instituted a search for facets like those discovered in rock-crystal, which, without altering chemical constitution, destroyed crystalline identity. He first found such facets in the tartrates, while he subsequently proved the neutrality of the paratartrate to be due to the equal admixture of right-handed and left-handed crystals, one of which, when the paratartrate was dissolved, exactly neutralised the other. Prior to Pasteur the left-handed tartrate was un- known. Its discovery, moreover, was supplemented by a series of beautiful researches on the compounds of right-handed and left-handed tartaric acid ; he having 178 LOUIS PASTEUB, previously extracted from the two tartrates acids which, in regard to polarised light, behaved like themselves. Such was the worthy opening of M. Pasteur's scientific career, which has been dwelt upon so frequently and emphatically by M. Eadot. The wonder however is, not that a searcher of such penetration as Pasteur should have discovered the facets of the tartrates, but that an investigator so powerful and experienced as Mitscherlich should have missed them. The idea of molecular dissymmetry, introduced by Biot, was forced upon Biot's mind by the discovery of a number of liquids, and of some vapours, which possessed the rotatory power. Some, moreover, turned the plane of polarisation to the right, others to the left. Crystal- line structure being here out of the question, the notion of dissymmetry, derived from the crystal, was transferred to the molecule. ' To produce any such phenomena, says Sir John Herschel, ' the -individual molecule must be conceived as unsymmetrically constituted.' The illustrations employed by M. Pasteur to elucidate this subject, though well calculated to give a general idea of dissymmetry, will, I fear, render but little aid to the reader in his attempts to realise molecular dissymmetry. Should difficulty be encountered here at the threshold of this work, I would recommend the reader not to be daunted by it, or prevented by it from going further. He may comfort himself by the assurance that the con- ception of a dissymmetric molecule is not a very precise one, even in the mind of M. Pasteur. One word more with regard to the parentage of preconceived ideas. M. Eadot informs us that at Strasburg M. Pasteur invoked the aid of helices and magnets, with a view to rendering crystals dissym- metrical at the moment of their formation. There can, I think, be but little doubt that such experiments HIS LIFE AND LABOUES. 179 were suggested by the pregnant discovery of Faraday, published in 1845. By both helices and magnets Faraday caused the plane of polarisation in perfectly neutral liquids and solids to rotate. If the turning of the plane of polarisation be a demonstration of mole- cular dissymmetry, then, in the twinkling of an eye, Faraday was able to displace symmetry by dissym- metry, and to confer upon bodies, which in their ordinary state were inert and dead, this power of rotation which M. Pasteur considers to be the ex- clusive attribute of life. The conclusion of M. Pasteur here referred to, which M. Kadot justly describes as 'worthy of the most serious consideration,' is sure to arrest the atten- tion of a large class of people, who, dreading * mate- rialism,' are ready to welcome any generalisation which differentiates the living world from the dead. M. Pasteur considers that his researches point to an irrefragable physical barrier between organic and inorganic Nature. Never, he says, have you been able to produce in the laboratory, by the ordinary processes of chemistry, a dissymmetric molecule in other words, a substance which, in a state of solution, where molecular forces are paramount, has the power of causing a polarised beam to rotate. This power be- longs exclusively to derivatives from the living world. Dissymmetric forces, different from those of the labora- tory, are, in Pasteur's mind, the agents of vitality. They alone build up dissymmetric molecules which baffle the chemist when he attempts to reproduce them. Such molecules trace their ancestry to life alone. ' Pourrait-on indiquer une separation plus profonde entre les produits de la nature vivante, et ceux de la nature minerale, que cette dissymetrie chez les uns, et son absence chez les autres?' It may be worth 180 LOUIS PASTED K, calling to mind that molecular dissymmetry is th< idea, or inference, the observed rotation of the plane of polarisation by masses of sensible magnitude being the fact, on which the inference is based. That the molecule, or unit brick, of an organism should be different from the molecule of a mineral is only to be expected, for otherwise the profound dis- tinction between them would disappear. And that one of the differences between the two classes of mole- cules should be the possession, by the one, of this power of rotation, and its non-possession by the other, would be a fact, interesting no doubt, but not surpris- ing. The critical point here has reference to the power and range of chemical processes, apart from the play of vitality. Beginning with the elements themselves, can they not be so combined as to produce organic com- pounds? Not to speak of the antecedent labours of Wohler and others in Germany, it is well known that various French investigators, among whom are some of M. Pasteur's illustrious colleagues of the Academy, have succeeded in forming substances which were once universally regarded as capable of being elaborated by plants and animals alone. Even with regard to the rotation of the plane of polarisation, M. Jungfleisch, an extremely able pupil of the celebrated Berthelot, affirms that the barrier erected by M. Pasteur has been broken down ; and though M. Pasteur questions this affirmation, it is at least hazardous, where so many supposed distinctions between organic and inorganic have been swept away, to erect a new one. For my part, I frankly confess my disbelief in its permanence. Without waiting for new facts, those already in our possession tend, I think, to render the association which M. Pasteur seeks to establish between dissym- metry and life insecure. Quartz, as a crystal, exerts HIS LIFE AND LABOUBS. 181 a very powerful twist on the plane of polarisation. Quartz dissolved exerts no power at all. The mole- cules of quartz, then, do not belong to the same category as the crystal of which they are the constituents ; the former are symmetrical, the latter is dissymmetrical. This, in my opinion, is a very significant fact. By the act of crystallisation, and without the intervention of life, the forces of molecules, possessing planes of sym- metry, are so compounded as to build up crystals which have no planes of symmetry. Thus, in passing from the symmetrical to the dissymmetrical, we are not com- pelled to interpolate new forces ; the forces extant in mineral nature suffice. The reasoning which applies to the dissymmetric crystal applies to the dissymme- tric molecule. The dissymmetry of the latter, however pronounced and complicated, arises from the compo- sition of atomic forces which, when reduced to their most elementary action, are exerted along straight lines. In 1865 I ventured, in reference to this subject, to define the position which I am still inclined to main- tain. ' It is the compounding, in the organic world, of forces belonging equally to the inorganic that con- stitutes the mystery and the miracle of vitality.' * Add to these considerations the discovery of Fara- day already adverted to. An electric current is not an organism, nor does a magnet possess life ; still, by their action, Faraday, in his first essay, converted over one hundred and fifty symmetric and inert aqueous solutions into dissymmetric and active ones.* 1 Art. ' Vitality,' Fragments of Science, 6th edit., vol. ii. p. 50. 1 In Farad ay ^induced dissymmetry, the ray having once passed through the body under magnetic influence, has its rotation doubled instead of neutralised, as in the case of quartz, on being reflected back through the body, Marbach has discovered that chlorate of soda produces circular polarisation in all directions through the crystal, while in quarts it occurs only in the direction of the axis. 182 LOUIS PASTEUR, Theory, however, may change, and inference may fade away, but scientific experiment endures for ever. Such durability belongs, in the domain of moleculai physics, to the experimental researches of M. Pasteur. The weightiest events of life sometimes turn upon small hinges ; and we now come to the incident which caused M. Pasteur to quit a line of research the aban- donment of which he still regrets. A German manu- facturer of chemicals had noticed that the impure commercial tartrate of lime, sullied with organic mat- ters of various kinds, fermented when it was dissolved in water and exposed to summer heat. Thus prompted, Pasteur prepared some pure right-handed tartrate of ammonia, mixed with it albuminous matter, and found that the mixture fermented. His solution, limpid at first, became turbid, and the turbidity he found to be due to the multiplication of a microscopic organism, which found in the liquid its proper aliment. Pasteur recognised in this little organism a living ferment. This bold conclusion was doubtless strengthened, if not prompted, by the previous discovery of the yeast- plant the alcoholic ferment by Cagniard-Latour and Schwann. Pasteur next permitted his little organism to take the carbon necessary for its growth from the pure paratartrate of ammonia. Owing to the opposition of its two classes of crystals, a solution of this salt, it will be remembered, does not turn the plane of polarised light either to the right or to the left. Soon after fermentation had set in, a rotation to the left was noticed, proving that the equilibrium previously exist- ing between the two classes of crystals had ceased. Marbach also discovered facets upon his crystals, resembling those of quartz. HIS LIFE AND LABOURS. 183 The rotation reached a maximum, after which it was found that all the right-handed tartrate had disap- peared from the liquid. The organism thus proved itself competent to select its own food. It found, as it were, one of the tartrates more digestible than the other, and appropriated it, to the neglect of the other. No difference of chemical constitution determined its choice ; for the elements, and the proportions of the elements, in the two tartrates were identical. But the peculiarity of structure which enabled the substance to turn the plane of polarisation to the right, also ren- dered it a fit aliment for the organism. This most remarkable experiment was successfully made with the seeds of our common mould, Penidllium glaucum. Here we find Pasteur unexpectedly landed amid the phenomena of fermentation. With true scientific instinct he closed with the conception that ferments are, in all cases, living things, and that the substances formerly regarded as ferments are, in reality, the food of the ferments. Touched by this wand, difficulties fell rapidly before him. He proved the ferment of lactic acid to be an organism of a certain kind. The ferment of butyric acid he proved to be an organism of a different kind. He was soon led to the fundamental conclusion that the capacity of an organism to act as a ferment depended on its power to live without air. The fermentation of beer was sufficient to suggest this idea. The yeast-plant, like many others, can live either with or without free air. It flourishes best in contact with free air, for it is then spared the labour of wresting from the malt the oxygen required for its sustenance. Supplied with free air, however, it prac- tically ceases to be a ferment ; while in the brewing- vat, where the work of fermentation is active, the budding tonda, is completely cut off by the sides of the vessel, 184 LOUIS PASTEUR, and by a deep layer of carbonic acid gas, from all con- tact with air. The butyric ferment not only lives without air, but Pasteur showed that air is fatal to it. He finally divided microscopic organisms into two great classes, which he named respectively aerobies and anatrobies, the former requiring free oxygen to main- tain life, the latter capable of living without free oxygen, but able to wrest this element from its com- binations with other elements. This destruction of pre-existing compounds and formation of new ones, through the increase and multiplication of the orga- nism, constitute the process of fermentation. Under this head are also rightly ranked the phe- nomena of putrefaction. As M. Kadot well expresses it, the fermentation of sugar may be described as the putrefaction of sugar. In this particular field M. Pas- teur, whose contributions to the subject are of the highest value, was preceded by Schwann, a man of great merit, of whom the world has heard too little. 1 Schwann placed decoctions of meat in flasks, sterilised the decoctions by boiling, and then supplied them with calcined air, the power of which to support life he showed to be unimpaired. Under these circumstances putrefaction never set in. Hence the conclusion of Schwann, that putrefaction was not due to the contact of air, as affirmed by Gray-Lussac, but to something suspended in the air which heat was able to destroy. This something consists of living organisms, which nourish themselves at the expense of the organic substance, and cause its putrefaction. The grasp of Pasteur on this class of subjects was embracing. He studied acetic fermentation, and 1 It was late in the day when the Eoyal Society made him a foreign member. HIS LIFE AND LABOURS. 185 found it to be the work of a minute fungus, the My- coderma aceti, which, requiring free oxygen for its nutrition, overspreads the surface of the fermenting liquid. By the alcoholic ferment the sugar of the grape-juice is transformed into carbonic acid gas and alcohol, the former exhaling, the latter remaining in the wine. By the Mycoderma aceti the wine is, in its turn, converted into vinegar. Of the experiments made in connection with this subject one deserves special mention. It is that in which Pasteur suppressed all albuminous matters, and carried on the fermentation with purely crystallisable substances. He studied the deterioration of vinegar, revealed its cause, and the means of preventing it. He denned the part played by the little eel-like organisms which sometimes swarm in vinegar-casks, and ended by introducing important ameliorations and improvements in the manufacture oi vinegar. The discussion with Liebig and other minor discussions of a similar nature, which M. Eadot has somewhat strongly emphasised, I will not here dwell upon. It was impossible for an inquirer like Pasteur to evade the question Whence come these minute organisms which are demonstrably capable of producing effects which constitute the bases of industries whereon whole populations depend for occupation and suste- nance ? He thus found himself face to face with the question of * spontaneous generation,' to which the researches of Pouchet had just given fresh interest. Trained as Pasteur was in the experimental sciences, he had an immense advantage over Pouchet, whose culture was derived from the sciences of observation. One by one the statements and experiments of Pouchet were explained or overthrown, and the doctrine of spon 186 LOUIS PASTEUR, taneous generation remained discredited until it waa revived with ardour, ability, and, for a time with suc- cess, by Dr. Bastian. A remark of M. Kadot's on page 103 needs quali- fication. 'The great interest of Pasteur's method consists,' he says, 'in its proving unanswerably that the origin of life in infusions which have been heated to the boiling point is solely due to the solid particles suspended in the air.' This means that living germs cannot exist in the liquid when once raised to a tem- perature of 212 Fahr. No doubt a great number of organisms collapse at this temperature ; some, indeed, as M. Pasteur has shown, are destroyed at a tempera- ture of 90 below the boiling point. But this is by no means universally the case. The spores of the hay- bacillus, for example, have, in numerous instances, suc- cessfully resisted the boiling temperature for one, two, three, four hours ; while in one instance eight hours' continuous boiling failed to sterilise an infusion of desiccated hay. The knowledge of this fact caused me a little anxiety some years ago when a meeting was projected between M. Pasteur and Dr. Bastian. For though, in regard to the main question, I knew that the upholder of spontaneous generation could not win, on the particular issue touching the death temperature he would probably have come off victor. The manufacture and maladies of wine next occupied Pasteur's attention. He had, in fact, got the key to this whole series of problems, and he knew how to use it. Each of the disorders of wine was traced to its specific organism, which, acting as a ferment, produced substances the reverse of agreeable to the palate. By the simplest of devices, Pasteur at a stroke abolished the causes of wine disease. Fortunately the foreign HIS LIFE AND LABOURS. 187 organisms which, if unchecked, destroy the best red wines, are extremely sensitive to heat. A temperature of 50 Cent. (122 Fahr. ) suffices to kill them. Bottled wines once raised to this temperature, for a single minute, are secured from subsequent deterioration. The wines suffer in no degree from exposure to this temperature. The manner in which Pasteur proved this, by invoking the judgment of the wine-tasters of Paris, is as amusing as it is interesting. Moved by the entreaty of his master, the illustrious Dumas, Pasteur took up the investigation of the diseases of silkworms at a time when the silk-husbandry of France was in a state of ruin. In doing so he did not, as might appear, entirely forsake his former line of research. Previous investigators had got so far as to discover vibratory corpuscles in the blood of the diseased worms, and with such corpuscles Pasteur had already made himself intimately acquainted. He was there- fore to some extent at home in this new investigation. The calamity was appalling, all the efforts made to stay the plague having proved futile. In June 1865 Pasteur betook himself to the scene of the epidemic, and at once commenced his observations. On the evening of his arrival he had already discovered the corpuscles, and shown them to 'others. Acquainted as he was with the work of living ferments, his mind was prepared to see in the corpuscles the cause of the epidemic. He fol- lowed them through all the phases of the insect's life through the eggs, through the worm, through the chrysalis, through the moth. He proved that the germ of the malady might be present in the eggs and escape detection. In the worm also it might elude micro- scopic examination. But in the moth it reached a de- velopment so distinct as to render its recognition imme- 13 188 LOUIS PASTEUR, diate. From healthy moths healthy eggs were sure to spring ; from healthy eggs healthy worms ; from healthy worms fine cocoons : so that the problem of the resto- ration to France of its silk-husbandry reduced itself to the separation of the healthy from the unhealthy moths, the rejection of the latter, and the exclusive employ- ment of the eggs of the former. M. Eadot describes how this is now done on the largest scale, with the most satisfactory results. The bearing of this investigation on the parasitic theory of communicable diseases was thus illustrated : Worms were infected by permitting them to feed for a single meal on leaves over which corpusculous matter had been spread; they were infected by inoculation, and it was shown how they infected each other by the wounds and scratches of their own claws. By the asso- ciation of healthy with diseased worms, the infection was communicated to the former. Infection at a dis- tance was also produced by the wafting of the corpus- cles through the air. The various modes in which communicable diseases are diffused among human popu- lations were illustrated by Pasteur's treatment of the silkworms. ' It was no hypothetical infected medium no problematical pythogenic gas that killed the worms. It was a definite organism.' ' The disease thus far described is that called pebrine, which was the principal scourge at the time. Another formidable malady was also prevalent, called flacherie, the cause of which, and the mode of dealing with it, were also pointed out by Pasteur. Overstrained by years of labour in this field, Pasteur was smitten with paralysis in October 1868. But this calamity did not prevent him from making a journey 1 These words were uttered at a time when the pythogenio theory was more in favour than it is now. HIS LIFE AND LABOUKS. 189 to Alais in January 1869, for the express purpose of combating the criticisms to which his labours had been subjected. Pasteur is combustible, and contradiction readily stirs him into flame. No scientific man now living has fought so many battles as he. To enable him to render his experiments decisive, the French Emperor placed a villa at his disposal near Trieste, where silkworm-culture had been carried on for some time at a loss. The success here is described as mar- vellous, the sale of cocoons giving to the villa a net profit of twenty-six millions of francs. 1 From the Imperial villa M. Pasteur addressed to me a letter, a portion of which I have already published. It may perhaps prove usefully suggestive to our Indian or Colonial authorities if I reproduce it here : ' Permettez-moi de terminerces quelques lignesque je dois dieter, vaincu que je suis par la maladie, en vous faisant observer que vous rendriez service aux Colonies de la Grande-Bretagne en repandant la con- naissance de ce livre, et des principes que j'etablis touchant la maladie des vers a soie.

The studies on wine prepare us for the * studies on beer,' which followed the investigation of silkworm diseases. The sourness, putridity, and other maladies of beer, Pasteur traced to special ferments of disease,' of a totally different form, and therefore easily distin- 1 The work on Diseases of SUknormt was dedicated to the Err. press of the French. 190 LOUIS PASTEUR, guishable from the true torula or yeast-plant. Many mysteries of our breweries were cleared up by this in- quiry. Without knowing the cause, the brewer not unfrequently incurred heavy losses through the use of bad yeast. Five minutes' examination with the micro- scope would have revealed to him the cause of the badness, and prevented him from using the yeast. He would have seen the true torula overpowered by foreign intruders. The microscope is, I believe, now everywhere in use. At Burton-on-Trent its aid was very soon in- voked. At the conclusion of his studies on beer M. Pasteur came to London, where I had the pleasure of conversing with him. Crippled by paralysis, bowed down by the sufferings of France, and anxious about his family at a troubled and an uncertain time, he appeared low in health and depressed in spirits. His robust appearance when he visited London, on the occasion of the Edinburgh Anniversary, was in marked and pleasing contrast with my memory of his aspect at the time to which I have referred. While these researches were going on, the Germ Theory of infectious disease was noised abroad. The researches of Pasteur were frequently referred to as bearing upon the subject, though Pasteur himself kept clear for a long time of this special field of inquiry. He was not a physician, and he did not feel called upon to trench upon the physician's domain. And now I would beg of him to correct me if, at this point of the Introduction, I should be betrayed into any statement that is not strictly correct. In 1876 the eminent microscopist, Professor Cohn, of Breslau, was in London, and he then handed me a number of his 'Beitrage,' containing a memoir by Dr. Koch on Splenic Fever (Milzbrand, Charbon, HIS LIFE AND LABOURS. 191 Malignant Pustule), which seemed to me to mark an epoch in the history of this formidable disease. With admirable patience, skill, and penetration Koch fol- lowed up the life-history of bacillus anthracis, the con- tagium of this fever. At the time here referred to he was a young physician holding a small appointment in the neighbourhood of Breslau, and it was easy to pre- dict, and indeed I predicted at the time, that he would soon find himself in a higher position. When I next heard of him he was head of the Imperial Sanitary Institute of Berlin. Koch's recent history is pretty well known in England, while his appreciation by the German Government is shown by the rewards and honours lately conferred upon him. Koch was not the discoverer of the parasite of splenic fever. Davaine and Eayer, in 1850, had ob- served the little microscopic rods in the blood of animals which had died of splenic fever. But they were quite unconscious of the significance of their observation, and for thirteen years, as M. Eadot informs us, strangely let the matter drop. In 1863 Davaine's attention was again directed to the subject by the researches of Pasteur, and he then pronounced the parasite to be the cause of the fever. He was opposed by some of his fellow-countrymen ; long discussions followed, and a second period of thirteen years, ending with the publication of Koch's paper, elapsed before M. Pasteur took up the question. I always, indeed, assumed that from the paper of the learned German came the impulse towards a line of inquiry in which M. Pasteur has achieved such splendid results. Things presenting themselves thus to my mind, M. Radot will, I trust, forgive me if I say that it was with very great regret that I perused the disparaging references to Dr. Koch which occur in the chapter on splenic fever. 192 LOUIS PASTEUR, After Koch's investigation, no doubt could be en- tertained of the parasitic origin of this disease. It completely cleared up the perplexity previously existing as to the two forms the one fugitive, the other perma- nent in which the contagium presented itself. I may here remark that it was on the conversion of the per- manent hardy form into the fugitive and sensitive one, in the case of bacillus subtilis and other organisms, that the method of sterilising by ' discontinuous heating ' introduced by me in February 1877 was founded. The difference between an organism and its spores, in point of durability, had not escaped the penetration of Pasteur. This difference Koch showed to be of para- mount importance in splenic fever. He moreover proved that while mice and guinea-pigs were infallibly killed by the parasite, birds were able to defy it. And here we come upon what may be called a hand- specimen of the genius of Pasteur, which strikingly illustrates its quality. Why should birds enjoy the immunity established by the experiments of Koch ? Here is the answer. The temperature which prohibits the multiplication of bacillus anthrads in infusions is 44 Cent. (111 Fahr.). The temperature of the blood of birds is from 41 to 42. It is therefore close to the prohibitory temperature. But then the blood- globules of a living fowl are sure to offer a certain resistance to any attempt to deprive them of their oxygen a resistance not experienced in an infusion. May not this resistance, added to the high tempera- ture of the fowl, suffice to place it beyond the power of the parasite ? Experiment alone could answer this question, and Pasteur made the experiment. By the ap- plication of cold water he lowered the temperature of a fowl to 37 or 38. He inoculated the fowl, thus chilled, with the splenic fever parasite, and in twenty HIS LIFE AND LABOUES. 193 four hours it was dead. The argument was clinched by inoculating a chilled fowl, permitting the fever to come to a head, and then removing the fowl, wrapped in cotton-wool, to a chamber with a temperature of 45. The strength of the patient returned as the career of the parasite was brought to an end, and in a few hours health was restored. The sharpness of the reasoning here is only equalled by the conclusiveness of the ex- periment, which is full of suggestiveness as regards the treatment of fevers in man. Pasteur had little difficulty in establishing the para- sitic origin of fowl-cholera; indeed, the parasite had been observed by others before him. But, by his suc- cessive cultivations, he rendered the solution pure. His next step will remain for ever memorable in the history of medicine. I allude to what he calls ' virus attenua- tion.' And here it may be well to throw out a few remarks in advance. When a tree, or a bundle of wheat or barley straw, is burnt, a certain amount of mineral matter remains in the ashes extremely small in comparison with the bulk of the tree or of the straw, but absolutely essential to its growth. In a soil lacking, or exhausted of, the necessary mineral constituents, the tree cannot live, the crop cannot grow. Now contagia are living things, which demand certain elements of life just as inexorably as trees, or wheat, or barley ; and it is not difficult to see that a crop of a given parasite may so far use up a constituent existing in small quantities in the body, but essential to the growth of the parasite, as to render the body unfit for the production of a second crop. The soil is exhausted, and, until the lost constituent is restored, the body is protected from any further attack of the same disorder. Some such expla- nation of non -recurrent diseases naturally presents itseli 194 LOUIS PASTEUE, to a thorough believer in the germ theory, and such was the solution which, in reply to a question, I ven- tured to offer nearly fifteen years ago to an eminent London physician. 1 To exhaust a soil, however, a para- site less vigorous and destructive than the really viru- lent one may suffice ; and if, after having by means of a feebler organism exhausted the soil without fatal result, the most highly virulent parasite be introduced into the system, it will prove powerless. 2 The general problem, of which Jenner's discovery was a particular case, has been grasped by Pasteur, in a manner, and with results, which five short years ago were simply unimaginable. How much ' accident ' had to do with shaping the course of his inquiries I know not. A mind like his resembles a photographic plate, which is ready to accept and develop luminous impressions, sought and unsought. In the chapter on fowl-cholera is described how Pasteur first obtained his attenuated virus. By successive cultivations of the parasite, he showed that after it had been a hundred times reproduced, it continued to be as virulent as at first. One necessary condition was, however, to be observed. It was essential that the cultures should rapidly succeed each other that the organism, before its transference to a fresh cultivating liquid, should not be left long in contact with air. When exposed to air for a considerable time the virus becomes so enfeebled that when fowls are inoculated with it, though they sicken for a time, they do not die. But this ' attenuated ' virus, which M. Eadot justly calls 'benign,' constitutes a sure protection against the virulent virus. It so exhaists the soil that the really fatal contagium fails 1 Sir Thomas Watson. liecent researches suggest other explanations. HIS LIFE AND LABOURS. 195 to find there the elements necessary to its reproduction and multiplication. Pasteur affirms that it is the oxygen of the air which, by lengthened contact, weakens the virus and converts it into a true vaccine. He has also weakened it by transmission through various animals. It waa this form of attenuation that was brought into play in the case of Jenner. The secret of attenuation had thus become an open one to Pasteur. He laid hold of the murderous virus of splenic fever, and succeeded in rendering it, not only harmless to life, but a sure protection against the virus in its most concentrated form. No man, in my opinion, can work at these subjects so rapidly as Pasteur without falling into errors of detail. But this may occur while his main position remains impreg- nable. Such a result, for example, as that ob- tained in presence of so many witnesses at Melun must remain an ever- memorable conquest of science. Having prepared his attenuated virus, and proved by laboratory experiments its efficacy as a protective vaccine, Pasteur accepted an invitation from the Presi- dent of the Society of Agriculture at Melun to make a public experiment on what might be called an agricul- tural scale. This act of Pasteur's is, perhaps, the boldest thing recorded in this book. . It naturally caused anxiety among his colleagues of the Academy, who feared that he had been rash in closing with the proposal of the President. But the experiment was made. A flock of sheep was divided into two groups, the members of one group being all vaccinated with the attenuated virus, while those of the other group were left unvaccinated. A number of cows were also subjected to a precisely similar treatment. Fourteen days afterwards, all the 196 LOUIS PASTEUR, sheep and all the cows, vaccinated and unvaccinated, were inoculated with a very virulent virus ; and three days subsequently more than two hundred persons assembled to witness the result. The ' shout of admi- ration,' mentioned by M. Eadot, was a natural outburst under the circumstances. Of twenty-five sheep which had not been protected by vaccination, twenty-one were already dead, and the remaining four were dving. The twenty-five vaccinated sheep, on the contrary, were ' in full health and gaiety.' In the unvaccinated cows intense fever was produced, while the prostration was so great that they were unable to eat. Tumours were also formed at the points of inoculation. In the vac- cinated cows no tumours were formed ; they exhibited no fever, nor even an elevation of temperature, while their power of feeding was unimpaired. No wonder that ' breeders of cattle overwhelmed Pasteur with applications for vaccine.' At the end of 1881 close upon 34,000 animals had been vaccinated, while the number rose in 1883 to nearly 500,000. M. Pasteur is now [1884] exactly sixty-two years of age ; but his energy is unabated. At the end of this volume we are informed thathe has already taken up and examined with success, as far as his experiments have reached, the terrible and mysterious disease of rabies or hydrophobia. Those who hold all communicable diseases to be of parasitic origin, include, of course, rabies among the number of those produced and pro- pagated by a living contagium. From his first contact with the disease Pasteur showed his accustomed pene- tration. If we see a man mad, we at once refer his madness to the state of his brain. It is somewhat singular that in the face of this fact the virus of a mad dog should be referred to the animal's saliva. The HIS LIFE AND LABOURS. 197 saliva is no doubt infected, but Pasteur soon proved the real seat and empire of the disorder to be the nervous system. The parasite of rabies had not been securely isolated when M. Eadot finished his task. But last May, at the instance of M. Pasteur, a commission was ap- pointed by the Minister of Public Instruction in France, to examine and report upon the results which he had up to that time obtained. A preliminary re- port, issued to appease public impatience, reached me before I quitted Switzerland this year. It inspires the sure and certain hope that, as regards the attenuation of the rabic virus, and the rendering of an animal by inoculation proof against attack, the success of M. Pasteur is assured. The Commission, though hitherto extremely active, is far from the end of its labours; but the results obtained so far may be thus summed up: Of six dogs unprotected by vaccination, three suc- cumbed to the bites of a dog in a furious state of madness. Of eight unvaccinated dogs, six succumbed to the intravenous inoculation of rabic matter. Of five unvaccinated dogs, all succumbed to inocu- lation, by trepanning, of the brain. Finally, of three-and-t\venty vaccinated dogs, not one was attacked with the disease subsequent to in- oculation with the most potent virus. Surely results such as those recorded in this book are calculated, not only to arouse public interest, but to excite public hope and wonder. Never before, during the long period of its history, did a day like the present dawn upon the science and art of medicine. Indeed, previous to the discoveries of recent times, medicine was not a science, but a collection of empirical rules, 198 LOUIS PASTEUR, HIS LIFE AND LABOURS. dependent for their interpretation and application upon the sagacity of the physician. How does England stand in relation to the great work now going on around her ? She is, and must be, behindhand. Scientific chauvinism is not beautiful in my eyes. Still, one can hardly see, without deprecation and protest, the English investigator handicapped in so great a race by short- sighted and mischievous legislation. A great scientific theory has never been accepted without opposition. The theory of gravitation, the theory of undulation, the theory of evolution, the dynamical theory of heat all had to push their way through conflict to victory. And so it has been with the Germ Theory of communicable diseases. Some outlying members of the medical profession dispute it- still. I am told they even dispute the communica- bility of cholera. Such must always be the course of things, as long as men are endowed with different degrees of insight. Where the mind of genius dis- cerns the distant truth, which it pursues, the mind not so gifted often discerns nothing but the extra- vagance, which it avoids. Names, not yet forgotten, could be given to illustrate these two classes of minds. As representative of the first class, I would name a man whom I have often named before, who fought, in England, the battle of the germ theory with persistent valour, but whose labours broke him down before he saw the triumph which he foresaw completed. Many of my medical friends will understand that I allude here to the late Dr. William Budd, of Bristol. The task expected of me is now accomplished, and the reader is here presented with a record, in which the verities of science are endowed with the interest of romance. 1884. THE RAINBOW AND ITS CONGENERS* THE oldest historic reference to the rainbow is known to all : * I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth. . . . And the bow shall be in the cloud ; and I shall look upon it, that I may remember the everlasting covenant between God and every living creature of all flesh that is upon the earth.' To the sublime concep- tions of the theologian succeeded the desire for exact knowledge characteristic of the man of science. What- ever its ultimate cause might have been, the proximate cause of the rainbow was physical, and the aim of science was to account for the bow on physical principles. Progress towards this consummation was very slow. Slowly the ancients mastered the principles of reflection. Still more slowly were the laws of refraction dug from the quarries in which Nature had embedded them. I use this language, because the laws were incorporate in Nature before they were discovered by man. Until the time of Alhazan, an Arabian mathematician, who lived at the beginning of the twelfth century, the views entertained regarding refraction were utterly vague and incorrect. After Alhazan came Roger Bacon and Vitellio, 1 who 1 A Friday evening discourse at the Royal Institution. * Whewell (History of the Inductive Sciencet, vol. i. p. 345) de- scribes Vitellio as a Pole. His mother was a Pole ; bnt Poggendorfl (Handirorterbuch d. exacten Wissensnhaften) claims Vitellio himseli 200 THE EAINBOW made and recorded many observations and measurements on the subject of refraction. To them succeeded Kepler, who, taking the results tabulated by his predecessors, applied his amazing industry to extract from them their meaning that is to say, to discover the physical prin- ciples which lay at their root. In this attempt he was less successful than in his astronomical labours. In 1604 Kepler published his 'Supplement to Vitellio,' in which he virtually acknowledged his defeat by enun- ciating an approximate rule, instead of an all-satisfying natural law. The discovery of such a law, which con- stitutes one of the chief corner-stones of optical science, was made by Willebrord Snell, about 162 1. 1 A ray of light may, for our purposes, be presented to the mind as a luminous straight line. Let such a ray be supposed to fall vertically upon a perfectly calm water- surface. The incidence, as it is called, is then perpen- dicular, and the 'ray goes through the water without deviation to the right or left. In other words, the ray in the air and the ray in the water form one continuous straight line. But the least deviation from the perpen- dicular causes the ray to be broken, or ' refracted,' at the point of incidence. What, then, is the law of re- fraction discovered by Snell? It is this, that no matter how the angle of incidence, and with it the angle of re- fraction, may vary, the relative magnitude of two lines, dependent on these angles, and called their sines, re- mains, for the same medium, perfectly unchanged. Measure, in other words, for various angles, each of these two lines with a scale, and divide the length of the longer one by that of the shorter ; then, however the lines individually vary in length, the quotient as a German, born in Thiiringen. ' Vitellio ' is described as a corrupt ion of Witelo. 1 Born at Leyden, 1591; died 1626. AND ITS CONGENERS. 201 yielded by this division remains absolutely the same. It is, in fact, what is called ' the index of refraction ' of the medium. Science is an organic growth, and accurate measurements give coherence to the scientific organism. Were it not for the antecedent discovery of the law of sines, founded as it was on exact measurements, the rainbow could not have been explained. Again and again, moreover, the angular distance of the rainbow from the sun had been determined and found constant. In this divine remembrancer there was no variableness. A line drawn from the sun to the rainbow, and another drawn from the rainbow to the observer's eye, always enclosed an angle of 41. Whence this steadfastness of position this inflexible adherence to a particular angle ? Newton gave to De Dominis l the credit of the answer ; but we really owe it to the genius of Descartes. He followed with his mind's eye the rays of light im- pinging on a raindrop. He saw them in part reflected from the outside surface of the drop. He saw them re- fracted on entering the drop, reflected from its back, and again refracted on their emergence. Descartes was acquainted with the law of Snell, and taking up his pen he calculated, by means of that law, the whole course of the rays. He proved that the vast majority of them escaped from the drop as divergent rays, and, on this account, soon became so enfeebled as to produce no sensible effect upon the eye of an observer. At one particular angle, however namely, the angle 41 afore- said they emerged in a practically parallel sheaf . In their union was strength, for it was this particular 1 Archbishop of Spalatro and Primate of Dalmatia. Fled to England about 1616 ; became a Protestant, and was made Dean of Windsor.

There is a certain form of emotion called intellectual pleasure, which may be excited by poetry, literature, Nature, or art. But I doubt whether among the plea- sures of the intellect there is any more pure and con- centrated than that experienced by the scientific man when a difficulty which has challenged the human mind for ages melts before his eyes, and re-crystallises as an illustration of natural law. This pleasure was doubtless experienced by Descartes when he succeeded in placing upon its true physical basis the most splendid meteor of our atmosphere. Descartes showed, moreover, that the ' secondary bow ' was produced when the rays of light underwent two reflections within the drop, and two refractions at the points of incidence and emer- gence. It is said that Descartes behaved ungenerously to Snell that, though acquainted with the unpublished papers of the learned Dutchman, he failed to acknow- ledge his indebtedness. On this I will not dwell, for I notice on the part of the public a tendency, at all events in some cases, to emphasise such shortcomings. The temporary weakness of a great man is often taken as a sample of his whole character. The spot upon the sun usurps the place of his ' surpassing glory.' This is not unfrequent, but it is nevertheless unfair. Descartes proved that, according to the principles of refraction, a circular band of light must appear in the heavens exactly where the rainbow is seen. But how are the colours of the bow to be accounted for ? Here his penetrative mind came to the very verge of the solution, but the limits of knowledge at the time barred his further progress. He connected the colours of the rainbow with those produced by a prism ; but then these AND ITS CONGENERS. 203 latter needed explanation just as much as the colours of the bow itself. The solution, indeed, was not possible until the composite nature of white light had been demonstrated by Newton. Applying the law of Snell to the different colours of the spectrum, Newton proved that the primary bow must consist of a series of concen- tric circular bands, the largest of which is red and the smallest violet; while in the secondary bow these colours must be reversed. The main secret of the rainbow, if I may' use such language, was thus revealed. I have said that each colour of the rainbow is carried to the eye by a sheaf of approximately parallel rays. But what determines this parallelism? Here our real difficulties begin, but they are to be surmounted by attention. Let us endeavour to follow the course of the solar rays before and after they impinge upon a spherical drop of water. Take, first of all, the ray that passes through the centre of the drop. This particular ray strikes the back of the drop as a perpendicular, its reflected portion returning along its own course. Take another ray close to this central one and parallel to it for the sun's rays when they reach the earth are parallel. When this second ray enters the drop it is refracted ; on reaching the back of the drop it is there reflected, being a second time refracted on its emergence from the drop. Here the incident and the emergent rays enclose a small angle with each other. Take, again, a third ray a little further from the central one than the last. The drop will act upon it as it acted upon its neighbour, the incident and emergent rays enclosing in this instance a larger angle than before. As we retreat farther from the central ray the enlargement of this angle continues up to a certain point, where it reaches a maximum, after which farther retreat from the central ray diminishes the angle. Now, a maximum 14 204 THE RAINBOW resembles the ridge of a hill, or a watershed, from which the land falls in a slope at each side. In the case before us the divergence of the rays when they quit the raindrop would be represented by the steep- ness of the slope. On the top of the watershed that is to say, in the neighbourhood of our maximum is a kind of summit-level, where the slope for some distance almost disappears. But the disappearance of the slope indicates, in the case of our raindrop, the absence of divergence. Hence we find that at our maximum, and close to it, there issues from the drop a sheaf of rays which are nearly, if not quite, parallel to each other These are the so-called ' effective rays ' of the rainbow. Let me here point to a series of measurements which will illustrate the gradual augmentation of the deflec- tion just referred to until it reaches its maximum, and its gradual diminution at the other side of the maxi- mum. The measures correspond to a series of angles of incidence which augment by steps of ten degrees. i d d 10 , . 10 60 . . 42 28' 20 . . 19 36' 70 . . 39 48' 30 . . 28 2(X 80 . . 31 4' 40 . . 35 36' 90 . . . 15 50 . . 40 40' 1 There is, in fact, a bundle of rays near the maximum, which, when they enter the drop, are converged by refraction almost exactly to the same point at its back. If the convergence were quitf exact, then the symmetry of the liquid sphere would cause the rays to quit the drop as they entered it that is to say, perfectly parallel. But inasmuch as the convergence is not quite exact, the parallelism aft er emergence is only approximate. The emergent rays cut each other at extremely sharp angles, thus forming a ' caustic ' which has f.n its asymptote the ray of maximum deviation. In the secondary bow we have to deal with a minimum, instead of a maximum, the crossing of the incident and emergent rays producing the oh?erved reversal of the colours. (See Engel and Shellbach's published dia- grams of the rainbow.) AND ITS CONGENERS. 205 The figures in the column i express the angles of inci- dence, while under d we have in each case the accom- panying deviation, or the angle enclosed by the incident and emergent rays. It will be seen that as the angle i increases, the deviation also increases up to 42 28', after which, although the angle of incidence goes on aug- menting, the deviation becomes less. The maximum 42 28' corresponds to an incidence of 60, but in reality at this point we have already passed, by a small quantity, the exact maximum, which occurs between 58 and 59. Its amount is 42 30'. This deviation corresponds to the red band of the rainbow. In a precisely similar manner the other colours rise to their maximum, and fall on passing beyond it ; the maximum for the violet band being 40 30'. The entire width of the primary rainbow is therefore 2, part of this width being due to the angular magnitude of the sun. We have thus revealed to us the geometric con- struction of the rainbow. But though the step here taken by Descartes and Newton was a great one, it left the theory of the bow incomplete. Within the rain- bow proper, in certain conditions of the atmosphere, are seen a series of richly-coloured zones, which were not explained by either Descartes or Newton. They are said to have been first described by Mariotte, 1 and they long challenged explanation. At this point our difficul- ties thicken, but, as before, they are to be overcome by attention. It belongs to the very essence of a maxi- mum, approached continuously on both sides, that on the two sides of it pairs of equal value may be found. The maximum density of water, for example, is 39 Fahr. Its density, when 5 colder and when 5 warmer than this maximum, is the same. So also with 1 Prior of St. Martin-sous-Beaune, near Dijon ; member of the French Academy of Sciences. Died in Paris, Mayl684. 206 THE RAINBOW regard to the slopes of a watershed. A series of paira of points of the same elevation can be found upon the two sides of the ridge ; and, in the case of the rainbow, on the two sides of the maximum deviation we have a succession of pairs of rays having the same deflection. Such rays travel along the same line, and add their forces together after they quit the drop. But light, thus reinforced by the coalescence of non-divergent rays, ought to reach the eye. It does so ; and were light what it was once supposed to be a flight of minute particles sent by luminous bodies through space then these pairs of equally-deflected rays would diffuse brightness over a large portion of the area within the primary bow. But inasmuch as light consists of waves, and not of particles, the principle of interfer- ence comes into play, in virtue of which waves alter- nately reinforce and destroy each other. Were the distance passed over by the two corresponding rays within the drop the same, they would emerge as they entered. But in no case are the distances the same. The consequence is that when the rays emerge from the drop they are in a condition either to support or to destroy each other. By such alternate reinforce- ment and destruction, which occur at different places for different colours, the coloured zones are produced within the primary bow. They are called ' super- numerary bows,' and are seen, not only within the primary, but sometimes also outside the secondary bow. The condition requisite for their production is, that the drops which constitute the shower shall all be of nearly the same size. When the drops are of different sizes, we have a confused superposition of the different colours, an approximation to white light being the con- sequence. This second step in the explanation of the rainbow was taken by a man the quality of whose AND ITS CONGENERS. 207 genius resembled that of Descartes or Newton, and who eighty-two years ago was appointed Professor of Natural Philosophy in the Royal Institution of Great Britain. I refer, of course, to the illustrious Thomas Young. 1 But our task is not, even now, complete. The finishing touch to the explanation of the rainbow was given by our eminent Astronomer Royal, Sir George Airy. Bringing the knowledge possessed by the founders of the undulatory theory, and that gained by subsequent workers, to bear upon the question, Sir George Airy showed, that, though Young's general principles were unassailable, his calculations were some- times wide of the maik. It was proved by Airy that the curve of maximum illumination in the rainbow does not quite coincide with the geometric curve of Descartes and Newton. He also extended our know- ledge of the supernumerary bows, and corrected the positions which Young had assigned to them. Finally, Professor Miller, of Cambridge, and Dr. Galle, of Berlin, illustrated by careful measurements with the theodolite the agreement which exists between the theory of Airy and the facts of observation. Thus, from Descartes to Airy, the intellectual force expended in the elucidation of the rainbow, though broken up into distinct personalities, might be regarded as that of an individual artist, engaged throughout this time in lovingly contemplating, revising, and perfecting his work. > We have thus cleared the ground for the series of experiments which constitute the subject of this dis- course. During our brief residence in the Alps this year, we were favoured with some weather of matchless 1 Young's Works, edited by Peacock, vol. L pp. 185, 293, 357. 203 THE RAINBOW perfection; but we had also our share of foggy and drizzly weather. On the night of the 22nd of Septem- ber the atmosphere was especially dark and thick. At 9 P.M. I opened a door at the end of a passage and looked out into the gloom. Behind me hung a small lamp, by which the shadow of my body was cast upon the fog. Such a shadow I had often seen, but in the present case it was accompanied by an appearance which I had not previously noticed. Swept through the darkness round the shadow, and far beyond, not only its boun- dary, but also beyond that of the illuminated fog, was a pale, white, luminous circle, complete except at the point where it was cut through by the shadow. As I walked out into the fog, this curious halo went in advance of me. Had not my demerits been so well known to me, I might have accepted the phenomenon as an evidence of canonisation. Benvenuto Cellini saw something of the kind surrounding his shadow, and ascribed it forthwith to supernatural favour. I varied the position and intensity of the lamp, and found even a candle sufficient to render the luminous band visible. With two crossed laths I roughly measured the angle subtended by the radius of the circle, and found it to be practically the angle which had riveted the attention of Descartes namely, 41. This and other facts led me to suspect that the halo was a circular rainbow. A week subsequently, the air being in a similar misty condition, the luminous circle was well seen from another door, the lamp which produced it standing on a table behind me. It is not, however, necessary to go to the Alps to witness this singular phenomenon. Amid the heather of Hind Head I have had erected a hut, to which I escape when my brain needs rest or my muscles lack vigour. The hut has two doors, one opening to the AND ITS CONGENERS. 209 north and the other to the south, and in it we have been able to occupy ourselves pleasantly and profitably during the recent misty weather. Removing the shade from a small petroleum lamp, and placing the lamp behind me, as I stood in either doorway, the luminous circles surrounding my shadow on different nights were very remarkable. Sometimes they were best to the north, and sometimes the reverse, the difference de- pending for the most part on the direction of the wind. On Christmas night the atmosphere was particularly favourable. It was filled with true fog, through which, however, descended palpably an extremely fine rain. Both to the north and to the south of the hut the luminous circles were on this occasion specially bright and well defined. They were, as I have said, swept through the fog far beyond its illuminated area, and it was the darkness against which they were projected which enabled them to shed so much apparent light. The * effective rays,' therefore, which entered the eye in this observation gave direction, but not distance, so that the circles appeared to come from a portion of the atmosphere which had nothing to do with their pro- duction. When the lamp was taken out into the fog, the illumination of the medium almost obliterated the halo. Once educated, the eye could trace it, but it was toned down almost to vanishing. There is some advantage, therefore, in possessing a hut, on a moor or on a mountain, having doors which limit the area of fog illuminated. I have now to refer to another phenomenon which is but rarely seen, and which I had an opportunity of witnessing on Christmas Day. The mist and drizzle in the early morning had been very dense ; a walk before breakfast caused the nap of my somewhat fluffy pilot- dress to be covered with minute water-globules, which, 210 THE KAINBOW against the dark background underneath, suggested the bloom of a plum. As the day advanced, the south- eastern heaven became more luminous ; and the pale disk of the sun was at length seen struggling through drifting clouds. At ten o'clock the sun had become fairly victorious, the heather was adorned by pendent drops, while certain branching grasses, laden with liquid pearls, presented, in the sunlight, an appearance of exquisite beauty. Walking across the common to the Portsmouth road my wife and I, on reaching it, turned our faces sunwards. The smoke-like fog had vanished, but its disappearance was accompanied, or perhaps caused, by the coalescence of its minuter particles into little globules, visible where they caught the light at a proper angle, but not otherwise. They followed every eddy of the air, upwards, downwards, and from side to side. Their extreme mobility was well calculated to suggest a notion prevalent on the Continent, that the particles of a fog, instead of being full droplets, are really little bladders or vesicles. Clouds are supposed to owe their power of flotation to this cause. This vesicular theory never struck root in England ; nor has it, I apprehend, any foundation in fact. . ' As I stood in the midst of these eddying specks, so visible to the eye, yet so small and light as to be per- fectly impalpable to the skin both of hands and face, I remarked, ' These particles must surely yield a bow of some kind.' Turning my back to the sun, I stooped down so as to keep well within the layer of particles, which I supposed to be a shallow one, and, looking towards the ' Devil's Punch Bowl,' saw the anticipated phenomenon. A bow without colour spanned the Punch Bowl. Though white and pale it was well defined, and exhibited an aspect of weird grandeur. Once or twice I fancied a faint ruddiness could be discerned on AND ITS CONGENERS. 211 its outer boundary. The stooping was not necessary, and as we walked along the new Portsmouth road, with the Punch Bowl to our left, the white arch marched along with us. At a certain point we ascended to the old Portsmouth road, whence, with a flat space of verj dark heather in the foreground, we watched the bow. The sun had then become strong, and the sky above us blue, nothing which could in any proper sense be called rain existing at the time in the atmosphere. Suddenly my companion exclaimed, ' I see the whole circle meeting at my feet I ' At the same moment the circle became visible to me also. It was the darkness of our immediate foreground that enabled us to see the lower half of the pale luminous band projected against it. We walked round Hind Head Common with the bo^* almost always in view. Its crown sometimes disap- peared, showing that the minute globules which pro- duced it did not extend to any great height in the atmosphere. In such cases two shining buttresses were left behind, which, had not the bow been pre- viously seen, would have lacked all significance. In some of the combes, or valleys, where the floating par- ticles had collected in greater numbers, the end of the bow plunging into the combe emitted a light of more than the usual brightness. During our walk the bow was broken and re-formed several times ; and, had it not been for our previous experience both in the Alps and at Hind Head, it might well have escaped atten- tion. What this colourless white bow lost in intensity, as compared with the ordinary coloured bow, was more than atoned for by its weirdness and its novelty to both observers. The white rainbow (farc-en-del blanc) was first described by the Spaniard Don Antonio de Ulloa, Lieu- tenant of the Company of Gentlemen Guards of the 212 THE RAINBOW Marine. By order of the King of Spain, Don Jorge Juan and Ulloa made an expedition to South America, an account of which is given in two amply-illustrated quarto volumes to he found in the library of the Royal Institution. The bow was observed from the summit of the mountain Pambamarca, in Peru. The angle subtended by its radius was 33 30', which is con- siderably less than the angle subtended by the radius of the ordinary bow. Between the phenomenon ob- served by us on Christmas Day, and that described by Ulloa, there are some points of difference. In his case fog of sufficient density existed to enable the shadows of him and his six companions to be seen, each how- ever only by the person whose body cast the shadow. Around the head of each were observed those zones of colour which characterise the ' spectre of the Brocken.' In our case no shadows were to be seen, for there was no fog-screen on which they could be cast. This im- plies also the absence of the zones of colour observed by Ulloa. The white rainbow has been explained in various ways. A learned Frenchman, M. Bravais, who has written much on the optical phenomena of the atmo- sphere, and who can claim the additional recommenda- tion of being a distinguished mountaineer, has sought to connect the bow with the vesicular theory to which I have just referred. This theory, however, is more than doubtful, and it is not necessary. 1 The genius of Thomas Young throws light upon this subject, as upon so many others. He showed that the whiteness of the bow was a direct consequence of the smallness of the drops which produce it. In fact, the wafted water- 1 The vesicular theory was combated very ably in France by the Abb6 Raillard, who has also given an interesting analysis of the rainbow at the end of his translation of my Nates on Light. AND ITS CONGENERS. 213 (pecks seen by us upon Hind Head 1 were the very kind needed for the production of the phenomenon. But the observations of TJlloa place his white bow dis- tinctly within the arc that would be occupied by the ordinary rainbow that is to say, in the region of super- numeraries and by the action of the supernumeraries upon each other Ulloa's bow was accounted for by Thomas Young. The smaller the drops, the broader are the zones of the supernumerary bows, and Young proved by calculation that when the drops have a diameter of -^V^h or TcVo^h f an inch, the bands overlap each other, and produce white light by their mixture. Unlike the geometric bow, the radius of the white bow varies within certain limits, which M. Bra- vais shows to be 33 30' and 41 46' respectively. In the latter case the white bow is the ordinary bow deprived of its colour by the superposition due to the smallness of the drops. In all the other cases it is produced by the action of the supernumeraries. The physical investigator desires not only to ob- serve natural phenomena but to re-create them to bring them, that is, under the dominion of experiment. From observation we learn what Nature is willing to reveal. In experimenting we place her in the witness- box, cross-examine her, and extract from her knowledge in excess of that which would, or could, be sponta- neously given. Accordingly, on my return from Swit- zerland last October, I sought to reproduce in the laboratory the effects observed among the mountains. My first object, therefore, was to obtain artificially a mixture of fog and drizzle like that observed from the 1 Had our refuge in the Alps been built on the southern side of the valley of the Rhone, so as to enable us to look with the suo behind us into the valley and across it, we should, I think, have fre- quently seen the white bow. 214 THE RAINBOW door of our Alpine cottage. A strong cylindrical cop- per boiler, sixteen inches high and twelve inches in diameter, was nearly filled with water and heated by gas- flames until steam of twenty pounds pressure was pro- duced. A valve at the top of the boiler was then opened, when the steam issued violently into the atmosphere, carrying droplets of water mechanically along with it, and condensing above to droplets of a similar kind. A fair imitation of the Alpine atmo- sphere was thus produced. After a few tentative ex- periments, the luminous circle was brought into view, and having once got hold of it, the next step was to enhance its intensity. Oil-lamps, the lime-light, and the naked electric light were tried in succession, the source of rays being placed in one room, the boiler in another, while the observer stood, with his back to the light, between them. It is not, however, necessary to dwell upon these first experiments, surpassed as they were by the arrangements subsequently adopted. My mode of proceeding was this. The electric light being placed in a camera with a conden sing-lens in front, the position of the lens was so fixed as to produce a beam sufficiently broad to clasp the whole of my head, and leave an aureole of light around it. It being de- sirable to lessen as much as possible the foreign light entering the eye, the beam was received upon a distant black surface, and it was easy to move the head until its shadow occupied the centre of the illuminated area. To secure the best effect it was found necessary to stand close to the boiler, so as to be immersed in the fog and drizzle. The fog, however, was soon discovered to be a mere nuisance. Instead of enhancing, it blurred the effect, and I therefore sought to abolish it. Allow- ing the steam to issue for a few seconds from the boiler, on closing the valve, the cloud rapidly melted AND ITS CONGENERS. 215 away, leaving behind it a host of minute liquid spherules floating in the beam. An intensely-coloured circular rainbow was instantly seen in the air in front of the observer. The primary bow was duly attended by its secondary, with the colours, as usual, reversed. The opening of the valve for a single second caused the bows to flash forth. Thus, twenty times in succes- sion, puffs could be allowed to issue from the boiler, every puff being followed by the appearance of this splendid meteor. The bows produced by single puffs are evanescent, because the little globules rapidly dis- appear. Greater permanence is secured when the valve is left open for an interval sufficient to discharge a copious amount of drizzle into the air. 1 Many other appliances for producing a fine rain have been tried, but a reference to two of them will suffice. The rose of a watering-pot naturally suggests a means of producing a shower ; and on the principle of the rose I had some spray-pro ducers constructed. In each case the outer surface was convex, the thin convex metal plate being pierced by orifices too small to be seen by the naked eye. Small as they are, fillets of very sensible magnitude issue from the orifices, but at some distance below the orifices the fillets shake themselves asunder and form a fine rain. The small 1 It is perhaps worth noting here, that when the camera and lens are used, the beam which sends its ' effective rays ' to the eye may not be more than a foot in width, while the circular bow engendered by these rays may be, to all appearance, fifteen or twenty feet in diameter. In such a beam, indeed, the drops which produce the bow must be very near the eye, for rays from the more distant drops would not attain the required angle. The apparent distance of the circular bow is often great in comparison with that of the originat- ing drops. Both distance and diameter may be made to undergo variations. In the rainbow we do not see a localised object, but receive a luminous impression, which is often transferred to a por- tion of the field of view far removed from the bow's origin. 216 THE KAINBOW orifices are very nable to get clogged by the particles suspended in London water. In experiments with the rose, filtered water was therefore resorted to. A large vessel was mounted on the roof of the Eoyal Institu- tion, from the bottom of which descended vertically a piece of compo-tubing, an inch in diameter and about twenty feet long. By means of proper screw- fittings, a single rose, or when it is desired to increase the magnitude or density of the shower, a group of two, three, or four roses, was attached to the end of the compo-tube. From these, on the turn- ing on of a cock, the rain fell. The circular bows produced by such rain are far richer in colour than those produced by the smaller globules of the con- densed steam. To see the effect in all its beauty and completeness, it is necessary to stand well within the shower, not outside of it. A waterproof coat and cap are therefore needed, to which a pair of goloshes may be added with advantage. A person standing outside the beam may see bits of both primary and secondary bows in the places fixed by their respective angles ; but the colours are washy and unimpressive. Within the shower, with the shadow of the head occupying its proper position on the screen, the brilliancy of the effect is extraordinary. The primary clothes itself in the richest tints, while the secondary, though less vivid, shows its colours in surprising strength and purity. But the primary bow is accompanied by appearances calculated to attract and rivet attention almost more than the bow itself. I have already mentioned the existence of effective rays over and above those which go to form the geometric bow. They fall within the primary, and, to use the words of Thomas Young, * would exhibit a continued diffusion of fainter light, AND ITS CONGENERS. 217 but for the general law of interference which divides the light into concentric rings.' One could almost wish for the opportunity of showing Young how lite- rally his words are fulfilled, and how beautifully his theory is illustrated, by these artificial circular rain- bows. For here the space within the primaries is swept by concentric supernumerary bands, coloured like the rainbow, and growing gradually narrower as they retreat from the primary. These spurious bows, as they are sometimes called, 1 which constitute one of the most striking illustrations of the principle of in- terference, are separated from each other by zones of darkness, where the light-waves on being added to- gether destroy each other. I have counted as many as eight of these beautiful bands, concentric with the true primary. The supernumeraries are formed next to the most refrangible colour of the bow, and there- fore occur within the primary circle. But in the secondary bow, the violet, or most refrangible colour, is on the outside; and, following the violet of the secondary, I have sometimes counted as many as five spurious bows. Some notion may be formed of the intensity of the primary, when the secondary is able to produce effects of this description. An extremely handy spray-producer is that em- ployed to moisten the air in the Houses of Parliament. A fillet of water, issuing under strong pressure from a small orifice, impinges on a little disk placed at a distance of about one-twentieth of an inch from the orifice. On striking the disk, the water spreads later- ally, and breaks up into an exceedingly fine spray. Here also I have used the spray-producer both singly and in groups, the latter arrangement being resorted to when showers of special breadth and density were re- 1 A term, I confess, not to my liking. 218 THE KAINBOW quired. In regard to primaries, secondaries, and super- numeraries, extremely brilliant effects have been obtained with this form of spray -producer. Tha quantity of water called upon being much less than that required by the rose, the fillet-and-disk instru- ment produces less flooding of the locality where the experiments are made. In this latter respect, the steam-boiler spray is particularly handy. A puff of two seconds' duration suffices to bring out the bows, the subsequent shower being so light as to render the use of waterproof clothing unnecessary. In other cases, the inconvenience of flooding may be avoided to a great extent by turning on the spray for a short time only, and then cutting off the supply of water. The vision of the bow being, however, proportionate to the duration of the shower, will, when the shower is brief, be evanescent. Hence, when quiet and continued contemplation of all the phenomena is desired, the observer must make up his mind to brave the rain. 1 In one important particular the spray-producer last described commends itself to our attention. With it we can operate on substances more costly than water, and obtain rainbows from liquids of the most various refractive indices. To extend the field of experiment in this direction, the following arrangement has been devised : A strong cylindrical iron bottle, wholly or partly filled with the liquid to be experimented on, is tightly closed by a brass cap. Through the cap passes a metal tube, soldered air-tight where it crosses the cap, and ending near the bottom of the iron bottle. To the free end of this tube is attached the spray-pro- ducer. A second tube passes also through the cap, but ends above the surface of the liquid. This second tube, 1 The rays which form the artificial bow emerge, as might b expected, polarised from the drops. AND ITS CONGENERS. 219 which is long and flexible, is connected with a larger iron bottle, containing compressed air. Hoisting the small bottle to a convenient height, the tap of the larger bottle is carefully opened, the air passes through the flexible tube to the smaller bottle, exerts its pres- sure upon the surface of the liquid therein contained, drives it up the other tube, and causes it to impinge with any required degree of force against the disk of the spray-producer. From this it falls in a fine rain. A great many liquids, including coloured ones, 1 have been tested by this arrangement, and very remarkable results have been obtained. I will confine myself here to a reference to two liquids, which commend them- selves on account of their cheapness and of the bril- liancy of their effects. Spirit of turpentine, forced from the iron bottle and caused to fall in a fine shower, produces a circular bow of extraordinary intensity and depth of colour. With paraffin oil or petroleum an equally brilliant effect is obtained. Spectrum analysis, as generally understood, occu- pies itself with atomic or molecular action, but physi- cal spectrum analysis may obvio'isly be brought to bear upon our falling showers. A composite shower that is to say, one produced by the mingled spray of two or more liquids could, it seems plain, be analysed and made to declare its constituents by the production of the circular rainbows proper to the re- spective liquids. This was found to be the case. In the ordinary rainbow the narrowest colour-band is pro- duced by its most refrangible light. In general terms, the greater the refraction, the smaller is the bow. Now, as spirit of turpentine and paraffin are both more refractive than water, it might be concluded that 1 Rose-aniline, dissolved in alcohol, produces a splendid bow with specially broad supernumeraries. 15 220 THE KAIKBOW in a mixed shower of water and paraffin, or water turpentine, the smaller and more luminous circle of the latter would be seen within the larger circle of the former. The result was exactly in accordance with this anticipation. Beginning with water and producing its two bows, then allowing the turpentine to shower down and mingle with the water within the large and beautifully-coloured water-wheel the more richly-coloured circle of the turpentine makes its appearance. Or beginning with turpentine and form- ing its concentrated iris ; on turning on the water- spray, though to the eye the shower seems absolutely homogeneous, its true character is instantly declared by the flashing out of the larger concentric aqueous bow. The water primary is accompanied by its secondary close at hand. Associated, moreover, with all the bows, primary and secondary, are the supernumeraries which belong to them ; and a more superb experimental illus- tration of optical principles it would be hardly possible to witness. It is not the less impressive because ex- tracted from the simple combination of a beam of light and a shower of rain. In the ' Philosophical Transactions' for 1835 the late Colonel Sykes gave a vivid description of a circular solar rainbow, observed by him in India during periods when fogs and mists were prevalent in the chasms of the Ghats of the Deccan. 'It was during such periods that I had several opportunities of witnessing that singular phenomenon, the circular rainbow, which, from its rareness, is spoken of as a possible occurrence only. The stratum of fog from the Konkun on some occasions rose somewhat above the level of the top of a precipice forming the north-west scarp of the hill-fort of H urreechundurghur, from 2,000 to 3,000 feet perpendicular, without coming AND ITS CONGENERS. 221 over upon the table-land. I was placed at the edge of the precipice, just without the limits of the fog, and with a cloudless sun at my back at a very low eleva- tion. Under such a combination of favourable circum- stances the circular rainbow appeared quite perfect, of the most vivid colours, one-half above the level on which I stood, the other half below it. Shadows in distinct outline of myself, my horse, and people ap peared in the centre of the circle as a picture, to which the bow formed a resplendent frame. My attendants were incredulous that the figures they saw under such ex- traordinary circumstances could be their own shadows, and they tossed their arms and legs about, and put their bodies into various postures, to be assured of the fact by the corresponding movements of the objects within the circle ; and it was some little time ere the superstitious feeling with which the spectacle was viewed wore off. From our proximity to the fog, 1 believe the diameter of the circle at no time exceeded fifty or sixty feet. The brilliant circle was accompanied by the usual outer bow in fainter colours.' Mr. E. Colbourne Baber, an accomplished and in- trepid traveller, has recently enriched the 'Transac- tions' of the Royal Geographical Society by a paper of rare merit, in which his travels in Western China are described. He made there the ascent of Mount an eminence of great celebrity. Its height is about 11,000 feet above the sea, and it is flanked on one side by a cliff ' a good deal more than a mile in height.' From the edge of this cliff, which is guarded by posts and chains, you look into an abyss, and if fortune, or rather the mists, favour you, you see there a miracle, which is thus described by Mr. Baber: 4 Naturally enough it is with some trepidation that pilgrims approach this fearsome brink, but they are 222 THE RAINBOW drawn to it by the hope of beholding the mysterious apparition known as the " Fo-Kuang," or " Glory of Buddha," which floats in mid-air half-way down. So many eye-witnesses had told me of this wonder that I could not doubt ; but I gazed long and steadfastly into the gulf without success, and came away disappointed, but not incredulous. It was described to me as a circle of brilliant and many-coloured radiance, broken on the outside with quick flashes, and surrounding a central disc as bright as the sun, but more beautiful. Devout Buddhists assart that it is an emanation from the aureole of Buddha, and a visible sign of the holiness of Mount 0. * Impossible as it may be deemed, the phenomenon does really exist. I suppose no better evidence could be desired for the attestation of a Buddhist miracle than that of a Baptist missionary, unless indeed it be, as in this case, that of two Baptist missionaries. Two gentlemen of that persuasion have ascended the moun- tain since my visit, and have seen the Glory of Buddha several times. They relate that it resembles a golden sun-like disc, enclosed in a ring of prismatic colours more closely blended than in the rainbow. . . . The missionaries inform me that it was about three o'clock in the afternoon, near the middle of August, when they saw the meteor, and that it was only visible when the precipice was more or less clothed in mist. It appeared to lie on the surface of the mist, and was always in the direction of a line drawn from the sun through their heads, as is certified by the fact that the shadow of their heads was seen on the meteor. They could get their heads out of the way, so to speak, by stooping down, but are not sure if they could do so by stepping aside. Each spectator, however, could see the shadows of the bystanders as well as his own projected on to the AND ITS CONGENERS. 223 appearance. They did not observe any rays spreading from it. The central disc they think is a reflected image of the sun, and the enclosing ring is a rainbow. The ring was in thickness about one-fourth of the dia- meter of the disc, and distant from it by about the 8 ime extent ; but the recollection of one informant was that the ring touched the disc, without any intervening space. The shadow of a head, when thrown upon it, covered about one-eighth of the whole diameter of the meteor. The rainbow ring was not quite complete in its lower part, but they attribute this to the interposi- tion of the edge of the precipice. They see no reason why the appearance should not be visible at night when the moon is brilliant and appositely placed. They profess themselves to have been a good deal surprised, but not startled, by the spectacle. They would con- sider it remarkable rather than astonishing, and are disposed to call it a very impressive phenomenon.' It is to be regretted that Mr. Baber failed to see the ' Glory,' and that we in consequence miss his own description of it. There seems a slight inadvertence in the statement that the head could be got out of the way by stooping. The shadow of the head must have alwaj s occupied the centre of the ' Glory.' Thus, starting from the first faint circle seen in the thick darkness at Alp Lusgen, we have steadily followed and developed our phenomenon, and ended by rendering the * Glory of Buddha ' a captive of the laboratory. The result might be taken as typical of larger things. [On Sept. 25, 1890, my friend M. Sarasin and my- pelf witnessed at Alp Lusgen a very perfect example of the white bow.

OUE lives are interwoven here below, frequently indeed most frequently without our knowing it. We are in great part moulded by unconscious inter- action. Thus, without intending it, the present repre- sentative of the Birkbeck family in Yorkshire has helped to shape my life. In 1856, or thereabouts, Mr. John Birkbeck aided in founding on the slope of a Swiss mountain the /Eggischhorn Hotel. The success of this experiment provoked in the neighbouring commune a spirit of rivalry and imitation, and accordingly, upon a bold bluff overlooking the great Aletsch glacier, was subsequently planted the Bel Alp Hotel. To the Bel Alp I went in my wanderings. Seeing it often I liked it well, until at length the thought dawned upon me of building a permanent nest there. Before doing so, how- ever, I imitated the birds chose, and was chosen by, a mate who, like myself, loved the freedom of the mountains, and we built our nest together. From that nest I have come straight to the Birkbeck Institution, so that the following chain of connection stretches between Mr. John Birkbeck and me. With- out him there would have been no ^ggischhorn ; with- out the /Eggischhorn there would have been no Bel Alp ; without Bel Alp there would have been no Tyndall's nest, and without that nest the person who now addresses you would undoubtedly be a different man from what he is. His bone would have been different THE BIRKBECK INSTITUTION. 225 bone ; his flesh different flesh ; nay, the very grey matter of his brain, which is said to be concerned in the pro- duction of thought, would have been different from what it now is. The inference is obvious that, should this lecture prove a failure and a bore, or should any hitch occur to cause me to break down in the middle of it, you are bound in common fairness to lay upon the shoulders of Mr. John Birkbeck, who has tampered so seriously with my bodily and mental constituents, a good round share of the blame. Thus I seek to shirk responsibility in regard to this lecture ; and I dare say you would forgive me if I went a little further in this somewhat ignoble line. It is the fashion of the hour. Some of England's most con- spicuous sons at the present day would seem to trace their moral pedigree to that mean old gardener who threw upon his wife the whole blame of eating the for- bidden fruit. In reference to the present occasion, I wrote to Mr. Norris from the Alps, asking him to choose between a purely scientific lecture and an address based on the experiences of my own life. He chose the latter. I do not, however, ask you to blame Mr. Norris, but to blame me if a chapter from the personal history of a worker, instead of proving a stimulus and an aid, should seem to you flat, stale, -and unprofitable. Every operation of husbandry, every stroke of states- manship, every movement of philanthropy, to be effec- tual and successful, must be executed at the proper time. If we sow in the autumn what ought to be sown in the spring, or if we sow in the spring what ought to be sown in the autumn, we can only reap disappoint- ment. Every public movement is tested by the ques- tion, ' Does it live ? ' and this may be translated into the question, Does it grow? ' For growth and multiplication constitute the evidence of life. Brought to this test 226 ADDRESS DELIVERED AT the movement inaugurated by Dr. George Birkbeck returned a full and conclusive answer. It responded, at the proper time, to a national need and to a need of human nature. Not only in the various districts of London, but also in various towns throughout the country, and even beyond the bounds of England, in- stitutions sprang up, founded on the model of the London Mechanics' Institution, which afterwards be- came the famous Birkbeck Institution, the anniversary of which we celebrate to-day. Speaking of the opportune beneficence of Dr. Birk- beck's movement reminds me that in the days of my youth, personally and directly, I derived profit from that movement. In 1 842, and thereabouts, it was my privilege to be a member of the Preston Mechanics' Institution to attend its lectures and make use of its library. A learned and accomplished clergyman, named, if I remember aright, John Clay, chaplain of the House of Correction, lectured from time to time on mechanics. A fine earnest old man, named, I think, Moses Holden, lectured on astronomy, while other lecturers took up the subjects of general physics, chemistry, botany, and physiology. My recollection of it is dim, but the instruction then received entered, I doubt not, into the texture of my mind, and influenced me in after-life. One experiment made in these lec- tures I have never forgotten. Surgeon Corless, I think it was, who lectured on respiration, explaining among other things the changes produced by the passage of air through the lungs. What went in as free oxygen came out bound up in carbonic acid. To prove this he took a flask of lime-water and, by means of a glass tube dipped into it, forced his breath through the water. The carbonic acid from the lungs seized upon the dissolved liine, converting it into carbonate of lime, THE BIRKBECK INSTITUTION. 227 which, being practically insoluble, was precipitated. All this was predicted beforehand by the lecturer ; but the delight with which I saw his prediction fulfilled, by the conversion of the limpid lime-water into a turbid mixture of chalk and water, remains with me as a memory to the present hour. The students ot the Birkbeck Institution may therefore grant me the honour of ranking myself among them as a fellow- btuilent of a former generation. At the invitation of an officer of the Royal Engi- neers, who afterwards became one of my most esteemed and intimate friends, I quitted school in 1839, to join a division of the Ordnance Survey. The profession of a civil engineer having then great attractions for me, I joined the Survey, intending, if pos.-ible, to make myself master of all its operations as a first step to- wards becoming a civil engineer. Draughtsmen were the best paid, and I became a draughtsman. But I habitually made incursions into the domains of the cal- culator and computer, and thus learned all their art. In due time the desire to make myself master of field operations caused rne to apply for permission to go to the field. The permission was granted by my excellent friend General George Wynne, 1 who then, as Lieutenant Wynne, observed and did all he could to promote my desire for improvement. Before returning to the office I had mastered all the mysteries of ordinary field work. But there remained a special kind of field work which had not been mastered the taking of trigonometrical observations. By good fortune some work of this kind was required at a time when all the duly-recognised observers were absent. Under the tutelage of a clever master, named Conwill, I had acquired, before quitting 1 Died at Cologne on June 27, 1890 ; and was buried there with military honours on June 30. 228 ADDRESS DELIVERED AT school, a sound knowledge of elementary geometry and trigonometry. Relying on this to carry me through, I volunteered to make the required ohservations. After pome hesitation, and a little chaff, a theodolite was con- fided to me. The instrument, you know, embraces an accurately- graduated horizontal circle for the measurement of horizontal angles, and a similarly graduated vertical circle for the taking of vertical angles. It is moreover furnished with a formidable array of clamp-screws, tangent-screws and verniers, sufficient to tax a novice to unravel them. My first care before applying the instrument was to understand its construction. Thia accomplished, I took the field with two assistants, who had to measure uphill and downhill along the sides of large triangles into which the whole country had been previously divided. At the same time angles of elevation had to be taken uphill and angles of depression downhill, and from these the true hori- zontal distance had to be calculated. The heights above the sea-level of the corners of the large triangles had been previously fixed with the utmost accuracy by a very powerful theodolite, and the measurements with my smaller instrument had to come pretty close to the accurate determiuation to save my work from rejection. Happily I succeeded, though there had been bets against me. The pay upon the Ordnance Survey was very small, but having ulterior objects in view, I considered the instruction received as some set-off to the smallness of the pay. It may prevent some of you young Birk- beckians from considering your fate specially hard, or from being daunted because from a very low level you have to climb a very steep hill, when I tell you that on quitting the Ordnance Survey in 1843, my salary was a little under twenty shillings a week. I have THE BIRKBECK INSTITUTION. 229 often wondered since at the amount of genuine happi- ness which a young fellow of regular habits, not caring for either pipe or mug, may extract even from pay like this. Then came a pause, and after it the mad time of the railway mania, when I was able to turn to some account the knowledge gained upon the Ordnance Survey. In Staffordshire, Cheshire, Lancashire, Dur- ham, and Yorkshire, more especially the last, I was in the thick of the fray. It was a time of terrible toil. The day's work in the field usually began and ended with the day's light, while frequently in the office, and more especially as the awful 30th of November drew near, there was little ditference between day and night, every hour of the twenty-four being absorbed in the work of preparation. The 30th of November was the latest date at which plans and sections of projected lines could be deposited at the Board of Trade, failure in this particular often involving the loss of thousands of pounds. One of my last pieces of field work in those days was the taking of a line of levels from the town of Keighley to the village of Haworth in York- shire. On a certain day, under grave penalties, these levels had to be finished, and this particular day was one of agony to me. The atmosphere seemed filled with mocking demons, laughing at- the vanity of my efforts to get the work done. My levelling-staves were snapped and my theodolite was overthrown by the storm. When things are at their worst a kind of anger often takes the place of fear. It was so in the present instance; I pushed doggedly on, and just at nightfall, when barely able to read the figures on my levelling-staff, I planted my last * bench-mark' on a tombstone in Haworth Churchyard. Close at hand was the vicarage of Mr. Bronte, where the genius waa 230 ADDRESS DELIVERED AT nursed which soon afterwards burst forth and astonished the world. Among the legal giants of those days Austin and Talbot stood supreme. There was something grand as well as merciless in the power wielded by those men in entangling and ruining a hostile witness; and yet it often seemed to me that a clear-headed fellow, who had the coolness, honesty, and courage not to go beyond his knowledge, might have foiled both of them. Then we had the giants of the civil engineers Stephenson, Brunei, Locke, Hawkshaw, and others. Judged by his power of fence, his promptness in calculation, and his general readiness of retort, George Bidder as a wit- ness was unrivalled. I have seen him take the breath out of Talbot himself before a committee of the House of Lords. Strong men were broken down by the strain and labour of that arduous time. Many pushed through, and are still amongst us in robust vigour. But some collapsed, while others retired, with large fortunes it is true, but with intellects so shattered that, instead of taking their places in the front rank of English states- men, as their abilities entitled them to do, they sought rest for their brains in the quiet lives of country gentle- men. In my own modest sphere, I well remember the refreshment occasionally derived from five minutes' sleep on a deal table, with Babbage and Callet's Loga- rithms under my head for a pillow. It was a time of mad unrest of downright mono- mania. In private residences and public halls, in London reception-rooms, in hotels and in the stables of hotels, among gipsies and costermongers, nothing was spoken of but the state of the share market, the pro- spects of projected lines, the good fortune of the ostler or pot-boy who, by a lucky stroke of business, had cleared ten thousand pounds. High and low, rich and THE BIRKBECK INSTITUTION. 231 poor, joined in the reckless game. During my profes- sional connection with railways I endured three weeks' misery. It was not defeated ambition ; it was not a rejected love-suit ; it was not the hardship endured in either office or field, but it was the possession of certain shares which I had purchased in one of the lines then afloat. The share list of the day proved the winding- sheet of my peace of mind. I was haunted by the Stock Exchange. Then, as now, I loved the blue span of heaven ; but when I found myself regarding it morning after morning, not with the fresh joy which, in my days of innocence, it had brought me, but solely with reference to its possible effect, through the harvest, upon the share market, I became at length so savage with myself, that nothing remained but to go down to my brokers and put away the shares as an accursed thing. Thus began and thus ended, without either gain or loss, my railway gambling. During this arduous period of my life my old ten- dencies, chief among which was the desire to grow intellectually, did not forsake me ; and, when railway work slackened, I accepted in 1817 a post as master in Queenwood College, Hampshire an establishment which is still conducted with success by a worthy Principal. There I had the pleasure of meeting Dr. Frankland, who had charge of the chemical laboratory. Queenwood College had been the Harmony Hall of the Socialists, which, under the auspices of the philan- thropist, Kobert Owen, was built to inaugurate the Millennium. The letters 'C of M,' Commencement of Millennium, were actually inserted in flint in the brickwork of the house. Schemes like Harmony Hall look admirable upon paper ; but inasmuch as they are formed with reference to an ideal humanity, they go to pieces when brought into collision with the real one. 232 ADDRESS DELIVERED AT At Queenwo,od I learned, by practical experience, that two factors go to the formation of a teacher. In regard to knowledge he must, of course, be master of his work. But knowledge is not all. There may be knowledge without power the ability to inform with- out the ability to stimulate. Both go together in the true teacher. A power of character must underlie and enforce the work of the intellect. There are men who can so rouse and energise their pupils so call forth their strength and the pleasure of its exercise as to make the hardest work agreeable. Without this power it is questionable whether the teacher can ever really enjoy his vocation with it I do not know a higher, nobler, more blessed calling, than that of the man who, scorning the e cramming ' so prevalent in our day, con- verts the knowledge he imparts into a lever, to lift, exercise, and strengthen the growing minds committed to his care. At the time here referred to I had emerged from some years of hard labour the fortunate possessor of two or three hundred pounds. By selling my services in the dearest market during the railway madness the sum might, without dishonour, have been made a large one; but I respected ties which existed prior to the time when offers became lavish and temptation strong. I did not put my money in a napkin, but cherished the design of spending it in study at a German university. I had heard of German science, while Caiiyle's references to German philosophy and literature caused me to re- gard them as a kind of revelation from the gods. Accordingly, in the autumn of 1848, Frankland and I started for the land of universities, as Germany is often called. They are sown broadcast over the country, and can justly claim to be the source of an important portion of Germany's present greatness. A portion, but not all. THE BIRKBECK INSTITUTION. 233 The thews and sinews of German men were not given by German universities. The steady fortitude and valiant laboriousness whjch have fought against, and triumphed over, the gravest natural disadvantages are not the result of university culture. But the strength and endurance which belong to the German, as a gift of race, needed enlightenment to direct it; and this was given by the universities. Into these establish- ments was poured that sturdy power which in other fields had made the wastes of Nature fruitful, and the strong and earnest character had thus superposed upon it the informed and disciplined mind. It is the coales- cence of these two factors that has made Germany great ; it is the combination of these elements which must prevent England from becoming small. We may bless God for our able journalists, our orderly Parlia- ment, and our free press; but we should bless Him still more for ' the hardy English root ' from which these good things have sprung. \Ve need muscle as well as brains, character and resolution as well as expertness of intellect. Lacking the former, though possessing the latter, we have the bright foam of the wave without its rock-shaking momentum. Our place of study was the town of Marburg in Hesse Cassel, and a very picturesque town Marburg is. It clambers pleasantly up the hillsides, and falls as pleasantly towards the Lahn. On a May day, when the orchards are in blossom, and the chestnuts clothed with their heavy foliage, Marburg is truly lovely. It has, moreover, a history. It was here that Saint Eliza- beth shed her holy influence and dispensed her mercies'. The noble double-spired church which bears her name, and contains her dust, stands here to commemorate her. On a high hilltop which dominates the town rises the fine old castle where, in the Kittersaal, Luther and 234 ADDRESS DELIVERED AT Zwingli held their famous conference on Consubstantia- tion and Transubstantiatiou. Here for a time lived William Tyndale, translator of the Bible into English, who was afterwards strangled and burnt in Vilvorden. Here Wolff expounded his philosophy, and here Denis Papin invented his digester, and is said to have in- vented a working steam-engine. The principal figure in the university at the time of our visit was Bunsen, who had made his name illustrious by chemical researches of unparalleled difficulty and importance, and by his successful application of chemical and physical principles to explain the volcanic phenomena of Iceland. It was be who first laid bare the secret of the geysers of Iceland and gave the true theory of their action. A very worthy old professor named Gerling kept the Observatory and lectured on physics. Professor Steg- mann, an excellent teacher, lectured on mathematics, Ludwig and Fick were at the Anatomical Institute, Waitz lectured on philosophy and anthropology, Hessel expounded crystallography, while my accomplished friend Knoblauch arrived subsequently from Berlin. The university at the time numbered about three hundred students, and it suited my mood and means far better than one of the larger universities. In the excellent biography of Dr. Birkbeck recently published by Dr. Godard, which to the writer of it was evidently a labour of love, the name of Birkbeck is re- ferred to the little river of that name which rises in the 'Birkbeck fells' in Westmoreland. 'Beck' is stream in the North, and ' Birk ' is birch, so that ' Birkbeck ' means Birchstream. Turned into German there would be very little change. For here also Birch is Birk, while Beck is Bach. In Marburg I lived on the Ketzerbach, a street through the middle of which ran an open brook fringed with acacias. Before the THE BFRKBECK INSTITUTION. 235 Reformation had gathered sufficient strength to put a stop to such things, a number of honest people, differ- ing in belief from a number of equally honest people who possessed the will and power to murder them, were here burnt to death, their calcined bones being thrown into the brook. Hence the name Ketzerbach Here- tics' Brook which survives to this hour. My lodging was a very homely one two rooms at the top of the house, one a study, the other a bedroom. I was imme- diately visited by a personage who offered his services as master of the robes. Bearing as he did a good character, he was at once engaged. This Stiefelwichser, or boot-cleaner, whose name was Steinmetz, carried with him besides his brushes a little cane about two feet long, and his vocation was to enter the rooms of the student early in the morning, gather up his clothes and boots, retire to the landing, whence after a few minutes' vigorous beating and brushing, he returned with everything clean, neat, and presentable for the day. My study was warmed by a large stove. At first I missed the gleam and sparkle from flame and ember, but soon became accustomed to the obscure heat. At six in the morning a small milchbrod and a cup of tea were brought to me. The dinner-hour was one, and for the first year or so I dined at a hotel. In those days living was cheap in Marburg. There was no railway to transport local produce to a distance, and this rendered it cheap at home. Our dinner consisted of several courses, roast and boiled, and finished up with sweets and dessert. The cost was a pound a month, or about eightpence per dinner. You must not suppose that I partook of all the courses. I usually limited myself to one of them, using even it in moderation, being already convinced that eating too much was quite aa 1C 236 ADDRESS DELIVEEED AT sinful, and almost as ruinous,, as drinking too much. Watch and ward were therefore kept over the eating. By attending to such things I was able to work, with- out weariness, for sixteen hours a day. With my Stiefelwichser I was soon at war. It wag not a 'declared war.' It was not a 'war of reprisals.' It was not even a struggle for supremacy, but a modest contest on my part for mere equality. Preferring working in the early morning to working late at night, I thought five o'clock a fair hour at which to begin the day. But my Stiefelwichser chose to come at four. For a time I allowed him so to come, without changing my hour ; but shame soon began to take possession of me. I considered his case, and compared his aims and inducements with my own. For the services he rendered me I allowed him the usual pay a few thalers for the Semester, or term. The thaler was three shillings. I asked myself what my aims and as- pirations were worth if they were unable to furnish a motive power equal to that which this poor fellow ex- tracted from his scanty wage. I tried to take refuge in a text of Scripture, and said to myself soothingly, ' The children of this world are always in their gene- ration wiser than the children of light.' It was very comforting for the moment to think of poor Steinmetz as a child of this world, and of his employer as a child of light. But in those days there existed under the same skin two John Tyndalls, one of whom called the other a humbug, accompanying this descriptive noun by a moral kick which, in the matter of getting up, effectually converted into a child of this world the child of light. For a long time I was always in a con- dition to look Steinmetz in the face, and return his ' Guten Morgen ' when he arrived. We afterwards re- laxed, and made our hour of meeting five ; and for the THE BIRKBECK INSTITUTION. 237 last year or so, having climbed my roughest eminences, and not feeling a continuance of the strain to be necessary, I was content if found well submerged in my tub before the clock of St. Elizabeth had finished ring- ing out six in the morning. Early risers are sometimes described as insufferable people They are, it is said, self-righteous filled with the pharisaical ' Lord, I thank thee that I am not as other men are I ' It may be so, but we have now to deal not with generalisations but with facts. My going to G-ermany had been opposed by some of my friends as quixotic, and my life there might perhaps be not unfairly thus described. I did not work for money ; I was not even spurred by * the last infirmity of noble minds.' I had been reading Fichte, and Emerson, and Carlyle, and had been infected by the spirit of these great men. Let no one persuade you that they were not great men. The Alpha and Omega of their teaching was loyalty to duty. Higher knowledge and greater strength were within reach of the man who unflinchingly enacted his best insight. It was a noble doctrine, though it may sometimes have inspired exhausting disciplines and unrealizable hopes. At all events it held me to my work, and in the long cold mornings of the German winter, defended by a Schlafrock lined with catskin, P usually felt a fresh- ness and strength a joy in mere living and working, derived from perfect health which was something different from the malady of self-righteousness. At Marburg I attended the lectures of many of the eminent men above mentioned, concentrating my chief attention, however, on mathematics, physics, and chemistry. I should like to have an opportunity of subjecting these lectures, especially those of Bunsen, to a riper judgment than mine was at thnt time. I 238 ADDRESS DELIVERED AT learnt German by listening to Bunsen, and as my knowledge of the language increased the lectures grew more and more fascinating. But my interest was alive from the first, for Bunsen was a master of the language of experiment, thus reaching the mind through the eye as well as through the ear. The lectures were full of matter. Notes of them are still in my possession which prove to me how full they were, ai,d how com- pletely they were kept abreast of the most advanced knowledge of the day. This is a use and a sense of the word ( advanced ' which may be safely commended to your sympathetic attention. In many directions it is easy enough to become advanced, but not in this one. Bunsen was a man of fine presence, tall, handsome, courteous, and with out a trace of affectation or pedantry. He merged himstrlf in his subject : his exposition was lucid, and his language pure ; he spoke with the clear Hanoverian accent which is so pleasant to English ears ; he was every inch a gentleman. After some experience of my own, I still look back on Bunsen as the nearest approach to my ideal of a university teacher. He sometimes seemed absent-minded, and, as he gazed through the window at the massive Elizabethen Kirche, appeared to be thinking of it rather than of his lecture. But there was no interruption, no halting or stammer- ing to indicate that he had been for a single moment forgetful. He lectured every day in winter, and twice a day in summer, beginning his course on organic chemistry at seven in the morning. After the lectures, laboratory work continued till noon. During this time no smoking was allowed in the laboratory, but at noon liberty as regards the pipe began, and was continued through the day. Bunsen himself was an industrious smoker. Cigars of a special kind were then sold in Marburg, called ' Bunsen'sche Cigarren ' ; they were THE EIRKBECK INSTITUTION. 239 very cheap and very bad, but they were liked by my illustrious friend, and were doubtless to him a source of comfort. Dr. Debus, the late distinguished professor of chemistry at the Koyal Naval College, Greenwich, was Bunsen's laboratory assistant at this time, and to him I was indebted for some lessons in blowpipe chemistry. Bunsen afterwards took me under his own charge, giving me Icelandic trachytes to analyse, and other work. Besides being a chemist, he was a profound physicist. His celebrated * Publicum * on electro-chemistry, to which we all looked forward as a treat of the highest kind, was physical from beginning to end. He was the intimate friend of W. Weber of Gottingen, and was well acquainted with the labours of that great electrician. Breaking ground in frictional electricity, he passed on to the phenomena and theory of the Voltaic pile. He was a great upholder of the famous Contact Theory, \\ hich had many supporters in Germany at the time, one of the foremost of these being the genial-minded Kohl- rausch. This theory, as you are well aware, has under- gone profound modifications. There are, no doubt, eminent philosophers amongst us who would pronounce the theory, in its first form, unthinkable, inasmuch as it implied the creation of force out of nothing. But the fact that some of the most celebrated scientific men in the world, with the illustrious Volta himself as their leader, accepted and saw nothing incongruous in the theory, shows how ' unthinkability ' depends upon the state of our knowledge. The laws of Ohm were ex- pounded with great completeness by Bunsen. Various modes of electric measurement were illustrated ; the electric light from the carbon battery, invented by himself, was iutroduced, the electric telegraph was ex- plained, Steinheil's researches in regard to the ' earth circuit 'were developed; and it was in these lectures 240 ADDRESS DELIVERED AT that I first beard an honouring and appreciative refer- ence to der Englische Bierbrauer, Joule. Stegmann, the professor of mathematics, was also a man of strong individuality. He lectured in a small room on the Hat which he occupied. This was the usual arrangement ; each professor had a lecture-room on his own floor, and the students in passing from lec- ture to lecture had sometimes to go from one end of Marburg to the other. The desks were of the most primitive description, and into them the inkhorns were securely fixed by means of spikes at the bottom. Be- sides attending his lectures I had private lessons from Professor Stegmann. He was what I have already de- scribed him to be, an excellent teacher. He lectured on analysis, on analytical geometry of two and three dimensions, on the differential and integral calculus, on the calculus of variations, and on theoretical mechanics. In mathematics he appeared to be entirely at home. I have sometimes seen him, after he had almost wholly covered his blackboard with equations, suddenly discover that he had somewhere made a mis- take. When this occurred he would look perplexed, shuffle his chalk vaguely over the board, move his tongue to and fro between his lips, until he had hit upon the error. His face would then flush, and he would dash forward with redoubled speed and energy, clearing up every difficulty before the end of the lec- ture. It was he who gave me the subject of my disser- tation when I took my -degree. Its title in English was * On a Screw Surface with Inclined Generatrix, and on the Conditions of Equilibrium on such Surfaces.' One evening, after he had given me this subject, I met him at a party and asked him a question, which I did not dream of as touching the solution of the problem. But he smiled and said, ' Yes, Herr Tyndall, but if THE BIRKBECK INSTITUTION. 241 I tell you that I must tell you a great deal more.' I thought he meant to insinuate that I wished for illegi- timate aid in the working out of my theme. I shrank together, and resolved that if I could not, without the slightest aid, accomplish the work from beginning to end, it should not be accomplished at all. Wandering among the pinewoods, and pondering the subject, I became more and more master of it ; and when my dis- sertation was handed in to the Philosophical Faculty, it did not contain a thought that was not my own. One of my experiences at Marburg may be Worth noting. For a good while I devoted myself wholly to the acquisition of knowledge; heard lectures and worked in the laboratory abroad, and studied hard at home. When a boy at school I had read an article, probably by Addison, on the importance of order in the distribution of our time, and for the first year or so my time was ordered very stringently, specified hours being devoted to special subjects of study. But in process of time I began the attempt of adding to knowledge as well as acquiring it. My first little physical investigation was on a subject of extreme simplicity, but by no means devoid of scientific interest ' Phenomena of a Water- jet.' Among other things, I noticed that the musical sound of cascades and rippling streams, as well as the sonorous voice of the ocean, was mainly if not wholly due to the breaking of air-bladders entangled in the water. There is no rippling sound of water u mccom- panied by bubbles of air. This inquiry was followed by others of a more complicated and difficult kind. Well, over and over again after work of this description had begun, I found myself infringing my programme of study. Discontent and self-reproach were the first result. But it was soon evident that a rigid ordering of time would now be out of place. You could not 242 ADDRESS DELIVERED AT call up at will the spirit of research. It was like that other spirit which cometh when it listeth, an. Cluef authority: Dean Peacock's Life of Young. EAELY LIFE AND STUDIES. 249 age of four years, he had read the Bible twice through. At the age of six he learnt by heart the whole of Gold- smith's 'Deserted Village.' His first formal teachers were not successful, and an aunt in those early days appears to have been more useful to him than anybody else. When not quite seven years of age, he was placed at what he calls a miserable boarding-school at Stapleton, near Bristol. But he soon became his own tutor, dis- tancing in his studies those who were meant to teach him. In March 1782 he was sent to the school of Mr. Thompson, at Compton, in Dorsetshire, of whose liberality and largeness of mind Young spoke after- wards with affectionate recognition. Here he worked at Greek and Latin, and read a great many books in both languages. He also studied mathematics and book-keeping. Of pregnant influence on his future life was the reading of Martin's 4 Lectures on Natural Philosophy,' and Ry land's ' Introduction to the New- tonian Philosophy.' He read with particular delight the optical portions of Martin's work. An usher of the school, named Jeffrey, taught him how to make tele- scopes and to bind books. The early years of Young and Faraday thus inosculate, the one, however, pursuing bookbinding as an amusement, and the other as a profession. Young borrowed a quadrant from an in- telligent saddler named Atkins, and with it determined the principal heights in his neighbourhood. He took to botany for a time, but was more and more drawn towards optics. He constructed a microscope. The disentangling of difficult problems was his delight. Seeing some fluxional symbols in Martin's work, he at- tacked the study of fluxions. Priestley on Air was read and understood, while the Italian language was mastered by the aid of one of his schoolfellows named Fox. 250 THOMAS YOUNO. After leaving Compton, he devoted himself to the study of Hebrew. Mr. Toulmin, of whom Young speaks with affection, lent him grammars of the Hebrew, Chaldee, Syriac, and Samaritan languages, all of which he studied with diligence and delight. Mr. Toulmin also lent him the Lord's Prayer in more than a hundred languages, the examination of which gave him extra- ordinary pleasure. Through one of those accidents which enter so largely into the tissue of human life, Young found himself at Youngsbury, near Ware, in Hertfordshire. It was a strong testimony to his talent and character, that Mr. Barclay at this time accepted him as the preceptor of his grandson, Mr. Hudson Grur- ney, although Young was then little more than fourteen, and his pupil only a year and a half younger than him- self. Thus began a lifelong friendship between him and Hudson Grurney. Young spent five years at Youngs- bury, which he deemed the most profitable years of his life. He spent the winter months in London, visiting booksellers' shops and hearing occasional lectures. He kept a journal in Hertfordshire, the first entry of which informs us that he had written out specimens of the Bible in thirteen different languages. It is recorded of Young that, when requested by an acquaintance, who presumed somewhat upon his youthful appearance, to exhibit a specimen of his handwriting, he very delicately rebuked the inquiry by writing a sentence in his best style in fourteen different languages. Although the catalogue of Young's books might give the impression that he was a great reader, his reading was limited ; but whatever he read, he completely mastered. Fichte compared the reading of Reviews to tlie smoking of tobacco, affirming that the two occupa- tions were equally pleasant, and equally profitable. Young, in this sense, was not a smoker. Whatever EARLY LIFE AND STUDIES. 251 study he began, he never abandoned; and it was, saya Dean Peacock, in his 'Life of Young,' to his steadily keeping to the principle of doing nothing by halves, that he was wont in after-life to attribute a great part of his success as a scholar and a man of science. Young's mother was the niece of Dr. Brockle.>by, and this eminent London physician appears to have taken the greatest interest in the development of his youthful relative. He nevertheless occasionally gave Young a rap over the knuckles for what he called his ' prudery.' We all know the strenuous and honourable opposition that has been always offered to negro slavery by the Society of Friends. In carrying out their princi- ples, they at one time totally abstained from sugar, lest by using it they should countenance the West Indian planters. Young here imitated the conduct of his sect, which Dr. Brocklesby stigmatised as ' prudery.' ' My late excellent friend Mr. Day,' says the Doctor, 'the author of " Sandford and Merton," abhorred the base traffic in human lives as much as you can do ; and even Mr. Granville Sharp, one of the earliest writers on the subject, has not done half as much service as Mr. Day in the above work. And yet Mr. Day devoured daily as much sugar as I do. Keformation,' adds the Doctor, 4 must take its rise elsewhere, if ever there is a general mass of public virtue sufficient to resist such private interests.' Over and above his classical reading, from 1790 to 1792, Young read Simpson's ' Fluxions,' the ' Principiu ' and ' Optics ' of Newton, and many of the works of other famous authors, including Bacon, Linnaeus, Boerhaave, Lavoisier, Higgins, and Black. He confined himself co works of the highest stamp. He mastered Corueille and Eacine, read Shakespeare, Milton, Blackstone, and Burke. But he was, adds his biographer, ' contented 17 252 THOMAS YOUNG. to rest in almost entire ignorance of the popular literature of the day.' I must, however, hasten over the early years and acquirements of this extraordinary personality. During his youth he had none of the assistance which is usually within the reach of persons of position in England. All that I have here mentioned, and a vast deal more, he had acquired without having entered either a public school or a university. As a classic, he was, we are assured, both precise and profound. As a mathe- matician, he was many-sided, original, and powerful. Such an education, however, though well calculated to develop the strength of the individual, was not, in Peacock's opinion, the best calculated to place Young in sympathy with the mind of his age. 'He was, throughout life, destitute of that intellectual fellow- feeling (if the phrase may be used) which is so neces- sary to form a successful teacher or lecturer, or a luminous and successful writer.' Young was intended for the medical profession, and his medical studies began in 1792. He came to London, and attended the lectures of Dr. Baily, Mr. Cruikshanks, and John Hunter. He made the acquaintance of Burke, Windham, Frederick North, Sir Joshua Eeynolds, and Dr. Lawrence. By the advice of Burke he studied the philosophical works of Cicero. The bent of Young's moral character may be inferred from the quotations which he habitually entered in his commonplace book. Here is one of them : ' For my part,' says Cicero, ' I think the man who possessed that strength of mind, that constitutional tendency to temperance and virtue, which would lead him to avoid all enervating indulgences, and to complete the whole career of life in the midst of labours of the body and efforts of the mind ; whom EARLY LIFE AND STUDIES. 253 neitner tranquillity nor relaxation, nor the flattering attentions of bis equals in age and station, nor public games nor banquets would delight; who would regard nothing in life as desirable which was not united with dignity and virtue ; such a man I regard as being, in my judgment, furnished and adorned with some special gifts of the gods.' His medical studies were pursued with the thorough- ness which marked everything Young took in hand. He was an assiduous attendant at the best lectures. His delight in optics naturally drew him to investigate the anatomical structure of the eye. In regard to this structure it will be remembered that in front is the cornea, holding behind it the aqueous humour ; then comes the iris, surrounding the aperture called the pupil, at the back of which we have the crystalline lens. Behind this, again, is the vitreous humour, which constitutes the great mass of the eye. Thus, optically considered, the eye is a compound lens of great com- plexity and beauty. Behind the vitreous humour is spread the screen of the retina, woven of fine nerve- fibres. On this screen, when any object looked at is distinctly seen, a sharply-defined image of the object is formed. Definition of the image is necessary to the distinctness of the vision. Were the optical arrange- ments of the eye rigid, distinct vision would be pos- sible only at one definite distance. But the eye can see distinctly at different distances. It has what the Germans call an Accommodationsvermogen a power of adjustment which liberates it from the thrall of rigidity. By what mechanical arrangement is the eye enabled to adjust itself both for near and distant objects? Young replied, 'By the alteration of the curvature of the crystalline lens.' His memoir on this subject was considered so meritorious, that it wa* 254 THOMAS YOUNG. printed in the 'Transactions of the Royal Society 1 ; and in the year following, at the age of twenty-one, he was elected a Fellow of the Society. Young's memoir evoked sharp discussion, hoth as regards the priority and the truth of the discovery. It was claimed by John Hunter, while its accuracy was denied by Hunter's brother-in-law, Sir Everard Home, who, jointly with Mr. Ramsden, affirmed that the adjustment of the eye depended on the changed curvature of the cornea. A couched eye that is to say, an eye from which the crystalline lens had been re- moved they affirmed to be capable of adjustment. In the face of such authorities Young, with the candoTir of a true man of science, abandoned the views he had enunciated. But it was only for a time. He soon resumed his inquiries, and proved to demonstration that couched eyes had no trace of the power ascribed to them. Before the time of Young, moreover, weighty authorities leaned to the view that the adjustment of the eye depended on the variation of the distance between the cornea and the retina. When near objects were viewed, it was thought that the axis was length- ened, the retina or screen being thereby thrown farther back. In distant vision the reverse took place. But Young proved beyond a doubt that no such variation in the length of the axis of the eye occurs ; and this has been verified in our own day by Helmholtz. The change in the curvature of the crystalline lens has been also verified by the most exact experiments. When we pass for instance, from distant to near vision, the image of a candle-flame reflected from the front surface of the leus becomes smaller, proving the lens to be then more sharply curved. When we pass from near to distant vision, the image becomes larger, proving the curvature of the lens to have diminished. The radius of curvature EAELY LIFE AND STUDIES. 255 of the lens under these circumstances has been shown to vary from six to ten millimeters. Young's theory of the adjustment of the eye has been therefore com- pletely verified. But it is still a moot point as to what the mechanism is by which the change of curvature is produced. Young thought that it was effected by the muscularity of the lens itself. The muscles, however, would require nerves to excite them, and it would be hardly possible, in the transparent humours of the eye, for such nerves to escape detection. They, however, have never been detected. While passing through Bath in 1794 Young, at the instance of Dr. Brocklesby, called upon the Duke of Richmond. The impression made by Young at this time may be gathered from a note addressed by the Duke to the Doctor in these terms : 'But I must tell you how pleased we all are with Mr. Young. I really never saw a young man more pleasing and engaging. He seems to have already acquired much knowledge in most branches, and to be studious of obtaining more. It comes out without affectation on all subjects he talks upon. He is very cheerful and easy without assuming anything ; and even on the peculiarity of his dress and Quakerism, he talked so reasonably, that one cannot wish him to alter himself in any one particular. In short, I end as I began, by assuring you that the Duchess and I are quite charmed with him.' The Duke, then Master of the Ordnance, was a very competent man. He was well acquainted with the instruments med in the great Trigonometrical Survey under his control. He offered to Young the post of private secretary. Young's acceptance would have brought wilhin his reach both honour and emolument. But to his credit be it recorded he refused the post, because 256 THOMAS YOUNG. its acceptance would have rendered necessary the aban- donment of his costume as a member of the Society of Friends. Soon afterwards he paid a visit to a cele- brated cattle-breeder near Ashbourne, and describes with vivid interest what Mr. Bickwell had accomplished by the process of artificial selection. Facts like these, presented afterwards to the pondering mind of Darwin, caused the great naturalist to pass from artificial to natural selection. Young visited Darwin's grandfather, and criticised his ' Zoonomia.' The inspection of Dr. Darwin's cameos, minerals, and plants, gave him great delight, the supreme pleasure being derived from the cameos. Dr. Darwin stated that he had borrowed much of the imagery of his poetry from the graceful expres- sion and vigorous conception which these cameos breathe. His opinion of his visitor was pithily ex- pressed in a letter of introduction to a friend in Edin- burgh. ' He unites the scholar with the philosopher, and the cultivation of modern arts with the simplicity of ancient manners.' Young went to Edinburgh to continue his studies in medicine. His reputation had gone before him, and he was welcomed in the best society of the northern capital. He met Bostock, Bancroft, Turner, Gibbs, Gregory, Duncan, Black, and Munroe. He dwells specially upon the lectures of John Bell, whose demonstrations in anatomy appeared to him to be of first-rate excellence. There is nothing that I have met in Dean Peacock's 'Life of Young' to denote that he was fervently reli- gious. The Ciceronian ' virtue,' rather than religious emotion, seemed to belong to his character. The hold which mere habit long exercised over him, and which loyalty to his creed had caused him to maintain at a period of temptation, became more and more relaxed. He gradually gave up the formal practices of Quakerism EARLY LIFE AND STUDIES. 257 in regard to dress and other matters. He took lessons in dancing, and appeared to delight in that graceful art. I remember the late Mr. Babbage telling me that once, upon a London stage, by the untimely raising of a drop-scene. Young was revealed in the attitude of a dancer. He assiduously attended the theatre. So, it may be remarked, did the profoundly religious Faraday. On leaving Edinburgh he paid a farewell visit to his friend Cruikshanks, who took him aside, and after much preamble, 'told me,' says Young, 'that he had heard that I had been at the play, and hoped that I should be able to contradict it. I told him that I had been seve- ral times, and that I thought it right to go. I know you are determined to discourage my dancing and sing- ing, and I am determined to pay no regard whatever to what you say.' After completing his studies at Edinburgh, Young went to the Highlands. The houses in which he was received show the consideration in which he was held. ] Ie visited the chief seats of learning, and the principal li braries, as a matter of course ; but he had also occasion to enjoy and admire * the good sense, frankness, cordial- ity of manners, personal beauty, and accomplishments' of the Scottish aristocracy. So greatly was he delighted v ith his visit to Gordon Castle, that before quitting it lie wrote thus : 'I could almost have wished to break or dislocate a limb by chance, that I might be detained against my will. I do not recollect that I have ever passed ray time more agreeably, or with a party whom I thought more congenial to my own disposition.' He visited Staffa, but took more pleasure in Pennant's plates and descriptions than in Fingal's Cave, or the scenery of the island. From the Duchess of Gordon he carried a letter of introduction to the Duke of Argyll, and spent some time at Inverary. In riding out he 258 THOMAS YOUffG. was given his choice to proceed leisurely with the Duke, or to ride with the ladies and be galloped over. His reply was, that of all things he liktd being galloped over, and he made his choice accordingly. He compares the two daughters of the Duke to Venus and Minerva, both being goddesses. He visited the Cum- berland lakes. But here it may be said, once for all, that Young was somewhat stunted in his taste for natural scenery. He was a man of the town, fond of social intercourse, and of intellectual collision. He could not understand the possibility of any man choosing to live in the country if the chance of living in London was open to him. At Liverpool he dined with Eoscoe, proceeding afterwards to Coalbrookdale and its ironworks. As previously at Carron, he was greatly impressed by the glare of the furnaces. Mr. W. Reynolds, who appeared to interest himself in physical experiments on a large scale, told him that he had the intention of making a flute 150 feet long and 2^ feet in diameter, to be blown by a steam-engine and played upon by barrels. From Young's letters it is evident that he then saw the value and necessity of what we now call technical education. In October 1795, he became a student in the University of Gottingen. He gives an account of his diurnal occupations, embracing attendance at lectures on history, on materia medica, on acute diseases, and on natural history. He is careful to note that he had also lessons twice a week from Blessmen, the academical dancing-master, and the same number of lessons on the clavichord from Forkel. Young's pursuit of ' personal accomplishments ' is considered by his biographer to have been excessive. At Gottingen he attended, on Bundays, tea dances or supper dances. The mother! EARLY LIFE AND STUDIES. 259 of handsome daughters appear to have been wary of the students, having reason * to fear a traitor in every young man.' He made at Gottingen the acquaintance of many famous professors of Heyne, Lichtenberg, Blumenbach, and others. He records a joke practised on the professor of geology which had serious conse- quences. The students were rather bored by the pro- fessor's compelling them to go with him to collect * petrifactions ; ' and the young rogues, says Young, ' in revenge, spent a whole winter in counterfeiting speci- mens and buried them in a hill which the good man meant to explore, and imposed them upon him as the most wonderful lusus naturcB.' Peacock adds the remark that the unhappy victim of this ' roguery ' died of mortification when the imposition was made known to him. Before taking his degree, it is customary for the student in German Universities to hand in a dissertation written by himself. This is circulated among the Professors and is followed by a public disputation. On July 16, Young did battle in the Auditorium, the sub- ject chosen for discussion being the human voice. He acquitted himself creditably, was complimented by those present, and received his degree as doctor of physic, surgery, and midwifery. In the thesis chosen for discussion, Young broke ground in those studies on sound which, for intrinsic merit, and suggesting as they did his subsequent studies on light, will remain for ever famous in the history of science. During a pause in the lectures he visited the Hartz Mountains, making himself acquainted with the scene of Goethe's Walpur- gisnacht on the summit of the Brocken. Wedgwood and Leslie accompanied him on this tour. The curious fossils dug up by the young men in the Unicorn's Cave at Schwarafeld excited curiosity and wonder, but no 260 THOMAS YOUNG. thing more. Their significance at that time had not been revealed. Hearing Kant so much spoken of in Germany, Young naturally attacked the 'Critique of Pure Reason,' but his other studies prevented him from devoting much time to the Critical Philosophy. To the portion of it which he read he attached no high value. He admitted Kant's penetration, but dwelt upon his confusion of ideas. The language of the * Critique ' he thought unpardonably obscure. He visited Brunswick, where, clothed in the proper costume, he was presented at Court. After the recep- tion came a supper, about twenty ladies sitting on one side of a table, and twenty gentlemen on the other. He endeavoured to converse with his neighbour, but found him either sulky or stupid. The dowager duchess, whom he likened to a spectre, made her appearance and began to converse pleasantly. When told that Young had studied at Gottingen, and that he was a doctor of medicine, she asked him whether he could feel a pulse, and whether the English or the Germans had the best pulses. Young replied that he had felt but one pulse in Germany the pulse of a young lady, and that it was a very good pulse. Gb'ttingen was then the foremost school of horsemanship in Europe. Young was passionately fond of this exercise, and there were no feats of horsemanship, however daring or difficult, which he did not attempt or accomplish. His muscu- lar power had been always remarkable, and he could clear a five-barred gate without touching it. H^ was better known among the students for his vaulting on a wooden horse than for -writing Greek. At a Court masquerade he appeared in the character of harlequin, which gave him an excellent opportunity of exhibiting his personal activity. Notwithstanding all this, he did cot quite like his life in Gottingen. The professors of EARLY LIFE AND STUDIES. 261 the University were worked too hard to leave much time for the receptions and social gatherings in which Young delighted. So he quitted Gottingen on August 28, ' with as little regret as a man can leave any place where he has resided nine months.' From Gottingen he walked to Cassel, and thence by Gotha, Erfurt, Weimar, and Jena, to Leipzig. He saw everything which to him was worth seeing, and as he carried letters of introduction from the most eminent men of the age, he was welcomed everywhere. Most of the professors were absent on their holiday, but at Weimar he conversed with Herder, who, though well versed in the English poets, cared nothing, it was said, about rhyme. At Jena he found Biitmer, who, at the age of eighty-three, was about to begin the publication of a general dictionary of all existing languages. He visited Dresden, the Saxon Switzerland, and the mines of Freiberg. Here he made the acquaintance of the celebrated Werner. From Freiberg he went to Berlin, where he dined twice with the English Ambassador, Lord Elgin, and once with Dr. Brown, a Welsh physi- cian in great favour with the King. Over the mono- tonous sandy flat that lies between the two cities he journeyed from Berlin to Hamburg. Detained here for a time by adverse winds, he was treated with great hospitality. One word in conclusion regarding the German schools of learning. Germany is now united and strong ; her sons are learned, and her prowess is proved. But the units from which her blended vigour Mas sprung ought not to be forgotten. These were the little principalities and powers of which she was formerly composed. Each of them asserted its individuality and independence by the establishment of a local Uni- versity, and all over Germany, in consequence, such 262 THOMAS YOUNG. institutions are sown broadcast. In these nurseries of mind and body, not only Bismarck and Von Moltke, but numbers of the rank and file of the German Army, found nutriment and discipline ; so that although, as long as her principalities remained separate, Germany as a whole was weak, the individual action of those small States educated German men so as to make them what we now find them to be. Two epochs of Young's career as a medical student have been now referred to his residence in Edinburgh, and his residence at Gottingen. Immediately after his return to England he became a fellow-commoner of Emanuel College, Cambridge. When the master of the college introduced him to those who were to be his tutors he jocularly said, ' I have brought you a pupil qualified to read lectures to his tutors.' On one occasion, in the Combination Eoom, Dr. Parr made some dogmatic observation on a point of scholarship. ' Bentley, sir,' said Young promptly and firmly, * was of a different opinion.' ' A smart young man that,' said Parr when Young quitted the room. His lack of humour and want of knowledge of popular literature sometimes made him a butt at the dinner-table, but he bore the banter with perfect good humour. The materials for Young's life at Cambridge are very scanty ; but there is one brisk and energetic letter, published by Dean Peacock, written by a man who was by no means partial to Young. ' Young,' he said, * was beforehand with the world in perceiving the defects of English mathematicians. He looked down upon the science, and would not cultivate the acquaintance of any of our philosophers. He seemed never to have heard the names of the poets and literary characters of the last century, and hardly ever spoke of English EARLY LIFE AND STUDIES. 263 literature.' According to Peacock's correspondent, there was about Young no pretence or assumption of supe- riority. ' He spoke upon the most difficult subjects as if he took it for granted that all understood the matter as well as himself. But he never spoke in praise of any of the writers of the day, and could not be persuaded to discuss their merits. He would speak of knowledge in itself of what was known or what might be known but never of himself or of any one else as having dis- covered anything, or as likely to do so. His language was correct, his utterance rapid, but his words were not those in familiar use, and he was therefore worse calcu- lated than any man I ever knew for the communication of knowledge.' This writer heard Young lecture at the Eoyal Institution, but thought that nothing could show less judgment than the method he adopted. * It was difficult to say how he employed himself at Cambridge. He read little ; l there were no books piled on his floor, no papers scattered on his table. His room had all the appearance of belonging to an idle man. He seldom gave an opinion, and never volunteered one ; never laid down the law like other learned doctors, or uttered sayings to be remembered. He did not think abstract- edly. A philosophical fact, a difficult calculation, an ingenious instrument, or a new invention, would en- gage his attention ; but he never spoke of morals, or metaphysics, or religion. Of the last, I never heard him say a word. Nothing in favour of any sect, or in opposition to any doctrine.' The impression made upon Young by Cambridge was, from first to last, entirely favourable. In those days, six years' study was indispensable before the degree of Bachelor of Medicine could be taken. Young 1 Critics and commentators must be great readers ; but creator* in science and philosophy do not always belong to this category. 264 THOMAS YOUNG. graduated in 1803, when he was thirty years of age, and five years more had to elapse before he could take the degree of M.D. Meanwhile he had begun the practice of medicine. Dr. Brocklesby died in 1797, on the night of a day when he had entertained his relative and some other friends at dinner. During dinner he seemed perfectly well, but he expired a few minutes after he went to bed. He left Young his house and furniture in Norfolk Street, Park Lane, his library, his prints, a collection of pictures chiefly selected by Sir Joshua Eeynolds, and about 10,000. in money. THE WAVE THEORY. On January 16, 1800, Young communicated to the Eoyal Society a memoir entitled ' Outlines and Ex- periments respecting Sound and Light.' In this paper he treated of the ' interference ' of sound, and his re- searches on this subject led him on to the discovery of the interference of light ' which has proved,' says Sir John Herschel, * the key to all the more abstruse and puzzling properties of light, and which would alone have sufficed to place its author in the highest rank of scientific immortality, even were his other almost in- numerable claims to such a distinction disregarded.' Newton considered the sensation of light to be aroused by the impinging of particles, inconceivably minute, against the retina. Huyghens, on the contrary, sup- posed the sensation of light to be aroused by the impact of minute waves. Young favoured the theory of undulation, and by his researches on sound he waa specially equipped for its thorough examination. Before he formally attacked the subject he gave, in a paper dealing with other matters, his reasons for espousing the wave theory. The velocity of light, for instance, in the same medium is constant. All refractions are THE WAVE THEORY. 265 attended with partial reflection. The dispersion of light is no more incompatible with this than with any other theory. Keflection and refraction are equally explicable on both suppositions. Huyghens indeed had proved this, and much more. Inflection may be better explained by the wave theory than by its rival. The colours of thin plates, which are perfectly unin- telligible on the common hypothesis, admit of complete explanation by the wave theory. In dealing with the colours of thin films, of which the soap-bubble offers a familiar example, Young first proved his mastery over the undulatory theory. In the pursuit of this great task he was able to apply to Newton's Theory of Fits the Theory of Waves, and to determine the lengths of the undulations corresponding to the dif- ferent colours of the spectrum. We now approach a phase of Young's career which more specially concerns us. The Royal Institution, as already stated, was founded by Count Rumford, sup- ported by many of the foremost men in England. The King was its patron, the Earl of Winchilsea its first president, while Lord Morton, Lord Egremont, and Sir Joseph Banks were its vice-presidents. On January 13, 1800, the Royal Seal was attached to the charter of the Royal Institution. Dr. Thomas Garnett was appointed Professor of Natural Philosophy and Chemistry. During his previous residence in Bavaria, Rumford had ruled" with beneficent but despotic sway, and the habit of mind thus engendered may have made itself felt in his behaviour to Dr. Garnett. At all events, they did not get on well together. On February 16, 1801, Davy was appointed Assistant Lecturer in Chemistry, Direc- tor of the Chemical Laboratory, and Assistant Editor of the Journals of the Institution. The post of Pro- 266 THOMAS YOUNG. fessor of Natural Philosophy was offered to Young, and he accepted it. The salary was to be 300. a year. On August 3, 1801, the following resolution was passed : 'Kesolved, that the Managers approve of the measures taken by Count Rumford, and that the appointment of Dr. Young be confirmed.' Young, it is said, was not successful as a lecturer in the Institution, and this Dr. Peacock ascribes to his early education, which gave him no opportunity of entering into the intellectual habits of other men. More probably the defect was due to a mental constitution, not plastic, like that of Davy or Faraday, in regard to exposition. Young now fairly fronted the undulatory theory of light. Before you is some of the apparatus he employed. I hold in my hand an ancient tract upon this subject by the illustrious Huyghens. It was picked up on a book- stall, and presented to me some years ago by Professor Dewar. In this tract Huyghens deals with refraction and reflection, giving a complete explanation of both ; and here, also, he enunciated a principle which now bears his name, and which forms one of the foundation- stones of the undulatory theory. The most formidable obstacle encountered by Young, and one which he never entirely surmounted, was an objection raised by Newton to the assumption of a fluid medium as the vehicle of light. Looking at the waves of water impinging on an isolated rock, Newton ob- served that the rock did not intercept the wave motion. The waves, on the contrary, bent round the rock, and set in motion the water at the back of it. Baring himself on this and similar observations, he says, 'Are not all hypotheses erroneous in which light is supposed to consist of a pre.^sion or motion propagated through a fli id medium ? If it consisted in pression or motion, it would bend into the shadow.' He instances the case THE WAVE THEORY. 267 of the sound of a bell being heard behind a hill which conceals the bell ; of the turning of corners by sound ; and then, with conclusive force, he points to the case of a planet coming between a fixed star and the eye, when the star is completely blotted out by the interposition of the opaque body. This, Newton urged, could not possibly occur if li<>ht were propagated by waves through a fluid medium, for such waves would infallibly stir the fluid behind the lanet, and thus obliterate the shadow. Young was firmly persuaded of the truth of the undulatory theory. The number of riddles that he had solved by means of it, the number of secrets he had unlocked, the number of difficulties he had crushed, rendered him steadfast in his belief; still, he never fairly got over this objection of Newton's. It was finally set aside by one of the most illustrious men that ever adorned the history of science. A young French officer of engineers, Augustin Fresnel, first really grappled with the difficulty and overthrew it. The principle of Huyghens, to which I have already re- ferred, is, that every particle, in every wave, acts as if it alone were a centre of wave motion. When you throw a stone into the Serpentine, circular waves or ripples are formed, which follow each other in succes- sion, retreating farther and farther from the point of disturbance. 1 Fix your attention on one of these cir- cular waves. The form of the wave moves forward, 1 ' I prove it thus, take heed now By experience, for if that tliou Threw in water now a stone Well wost thou it will make anone, A little roundell as a cercle, Peraventure as broad as a couercle, And right anone thou shalt see wele, That wheie cercle wil cause another whele, And that a third and so forth brother, Every cercle causing other,' CHAUCEB'S Hmiseof Fame. 18 268 THOMAS YOUNG. but the motion of its individual particles, at any mo- ment, is simply a vibration up and down. Now each oscillating particle of every moving wave, if left to itself, would produce a series of waves, not so high, but in other respects exactly similar to those produced by the stone. The coalescence of all these small waves produces another wave of exactly the same kind as that which started them. The principle that every particle of a wave acts independently of all other particles, while the waves produced by all the particles afterwards combine, is, as I have said, the great principle of Huyghens. Taken in conjunction with the interference of light, first established by Thomas Young, which proved that when waves coalesce or combine, they may either support each other or neutralise each other, the neutralisation being either total or partial, according as the opposition of the combining waves is complete or incomplete taking, I say, the principle of interference in conjunction with that of Huyghens, Fresnel proved that although light does diverge behind an opaque body, as Newton supposed that it would diverge, these divergent waves completely efface each other, pro- ducing the shadow due to the tranquillity of the medium which propagates the light. By reference to the waves of water, Young illus- trates, in the most lucid manner, the interference of the waves of light. He pictures two series of waves generated at two points near each other in a lake, and reaching a channel issuing from the lake. If the waves arrive at the same moment, neither series will destroy the other. If the elevations of both series coincide, they will, by their joint action, produce in the channel a series with higher elevations. But if the elevations of one series correspond to the depressions of the other, the ridges will exactly fill the furrows, smooth water THE WAVE THEORY. 269 in the channel being the result. * At least,' says Young, * I can discover no alternative, either from theory or from experiment. Now,' he continues, gathering con- fidence as he reasons, * I maintain that similar effects take place whenever two portions of light are thus mixed, and this I call the general law of the Inter- ference of Light.' The physical meaning of all the terms applied to light was soon fixed. Intensity depended upon the amplitudes of the waves. Colour depended on the lengths of the waves. Two series of waves coalesced and helped each other when one was any number of complete undulations, or, in other words, any even number of half-undulations, behind the other. Two series of waves extinguished each other when the one series was any odd number of semi-undulations behind the other. But inasmuch as white light is made up of innumerable waves of different lengths, such waves cannot all interfere at the same time. Some interfere totally, and destroy each other ; some partially ; while some add themselves together and enhance the effect. Thus, by interference, a portion only of the white light is destroyed, and the remaining portion is, as a general rule, coloured. Indeed most glowing and brilliant effects of coloration are thus produced. Young applied the theory successfully to explain the colours of striated surfaces which, in the hands of Mr. Eutherfurd and others, have been made to produce such splendid effects. The iridescences on the polished surfaces of mother- of-pearl are due to the striae produced by the edges of the shell-layers, which are of infinitesimal thickness; the fine lines dnovn by Coventry, Wollaston, and Barton upon glass also showed these colours. Barton after- wards succeeded in transferring the lines to steel and braes. Most of you are acquainted with the iridescence 270 THOMAS YOUNG. of Barton's buttons. A descendant of Mr. Barton has, I believe, succeeded in reproducing the instrument wherewith his grandfather obtained his brilliant effects. But the greatest triumph of Young in this field was the explanation of the beautiful phenomenon known as Newton's rings. The colours of thin plates were pro- fusely illustrated by the experiments of Hooke and Boyle, but Newton longed for more than illustrations. He desired quantitative measurement. The colour of the film was known to depend upon its thickness. Can this thickness be measured ? Here the unparalleled penetration of Newton came into play. He took a lens, consisting of a slice of a sphere of a diameter so large that a portion of the curved surface of the lens approximated to a plane surface. Upon this slightly convex surface he placed a plate of glass the surface of which was accurately plane. Squeezing them together, and allowing light to fall upon them, he observed those beautiful iris- circles with which his name will be for ever identified. The iris-colours were obtained when he employed white light. When monochromatic light was used he had simply successive circles of light and darkness. Here then, from the central point where the two glasses touched each other, Newton obtained a film of air winch gradually increased in thickness as he retreated from the point of contact. Whence this wonderful recurrence of light and darkness ? The very constitu- tion of light itself must be involved in the answer. His desire was now to ascertain the thickness of the film of air corresponding to the respective rings. Knowing the curvature of his lens, this was a matter of easy calculation. He measured the diameter of the fifth ring of the series. This might be accurately done with a pair of fine compasses, for the diameter was over the fifth of an inch in length. But it was the interval THE WAVE THEORY. 271 between the glasses corresponding to this distance that Newton required to know, and this he found by calcu- lation to be OTWoth of an inch. This, be it remem- bered, is the distance corresponding to the fifth ring. The interval corresponding to the first ring would be only a fifth of this, or, in other words, about rroinnrth of an inch. Such are the magnitudes with which we have to deal before the question ' What is Light? ' can be scientiBcally answered. Newton's explanation of the rings which he was the first to discover, though artificial in the highest degree, is marked by his profound sagacity. He was hampered by the notion of the * corporeity ' of light. He could not get over the objection raised by himself as to the impossibility of shadows in a fluid medium. He held therefore that light was due to the darting forth of minute particles in straight lines ; and he threw out the idea that colour might be due to the difference of ' big- ness ' in the particles. He endowed these particles with what he called fits of easy transmission and reflection. The dark rings, in his immortal experiment, were pro- duced where the light-particles were in their trans- missive * fit.' They went through both surfaces of the film of air, and were not thrown back to the eye. The bright rings occurred where the light-particles were in their reflective fit, and where, on reaching the second surface of the film, they were thrown back to the eye. The cardinal point here is, that Newton regarded the recurrence of light and darkness as due to an action confined to the second surface of the film. And here it was that Young came into irreconcilable collision vith him, proving to demonstration that the dark rings occurred where the portions of light reflected homboth, sides of the film extinguished each other by inter- ference, while the bright rings occurred where the light 272 THOMAS YOUNO. reflected from the two surfaces coalesced to enhance the intensity. Young next applied the wave theory to account for the diffraction or inflection of light that is to say, the effects produced by its bending round the edges of bodies. When a cone of rays, issuing from a very minute point, impinges on an opaque body, so as to embrace it wholly, the shadow of the body, if received upon a screen, exhibits fringes of colour. They follow so closely the contour of the opaque body, that Sir John Herschel compared them to the lines along the sea- coast in a map. If a very thin slip of card, or a hair, be placed within such a cone, it is noticed that besides the fringes outside the shadow, bands of colour occur within it ; the central, or brightest, band being always white when white light is employed. It is a singular and somewhat startling fact, that by the interposition of an opaque body, say a small circle of tinfoil, the point on which we should expect the centre of the shadow to faU is, by the joint action of diffraction and interference, illuminated to precisely the same extent as it is when the opaque circle is withdrawn. 1 In refer- ence to the interior fringes Young made the obser- vation, which is of primary importance, that if you intercept the light passing by one of the edges of the strip of card or of the hair, the fringes disappear. It requires the inflection of the waves round both edges of the object, and their consequent interference, to pro- duce these fringes. Young's attempt to explain the phenomena of dif- fraction was a distinct advance on the extremely arti- ficial hypothesis of Newton. Still his attempt was not so successful as his explanation of the colours of striated 1 A similar diffraction has been proved by Lord Eayleigh tc occur in the case of sound. TIIE WAVE THEORY. 273 surfaces and of thin, thick, and mixed plates. Here the young officer of engineers to whom I have already referred Fresnel entered the field. He presented ia 1815, to the French Institute, a memoir on Diffraction which marks an epoch in the history of the wave theory. It is usual, when such a paper is presented, to refer it to a * Commission,' who consider it and report upon its merits. The Commissionnairea in this instance were Arago and Prony. Arago had read the memoirs of Young in the 'Philosophical Transactions,' but had not understood their full significance. The study of Fresnel's memoir caused the full truth to flash upon him that his young countryman had been anticipated thirteen years pre- viously by Dr. Young. Fresnel had re-discovered the principle of interference independently, and, with pro- found insight and unrivalled experimental skill, had ap- plied it to the phenomena of diffraction. It was no light thing for Fresnel to find himself as regards the principle of interference suddenly shorn of his glory. He, how- ever, bore the shock with resignation. He might have readily made claims which would have found favour with his countrymen and with the world at large. But he did nothing of the kind. The history of science indeed furnishes no brighter example of honourable fairness than that exhibited throughout his too short life by the illustrious young Frenchman. Once assured that he had been anticipated whatever might have been the extent of his own labours, however indepen- dently he might have arrived at his results he unre- servedly withdrew all claim to the discovery. There is, I repeat, no finer example of scientific honour than that manifested by Augustin Fresnel. Fresnel was a powerful mathematician, and well versed in the best mathematical methods of his day. 274 THOMAS YOUNO. With enormous labour he calculated the positions where the phenomena of interference must display themselves in a definite way. He was, moreover, a most refined experimentalist, and having made his calculations, he devised instrumental means of the most exquisite deli- cacy with the vie^f of verifying his results. In this way he swept the field of diffraction practically clear of difficulty, solving its problems where even Young had failed. Truly, these were minds possessing gifts not pur- chasable with money! And round about the central labours of each, minor achievements of genius are to be found, which would be a fortune to less opulent men. I hardly know a more striking example of Young's pene- tration than his account of the spurious or supernume- rary bows observed within the true primary rainbow. These interior bows are produced by interference. It is not difficult, by artificial means, to form them in great number and beauty. This is a subject on which I worked assiduously a couple of years ago. 1 And often, when looking at these wondrous interference circles, the words of Young seemed to me like the words of prophecy. The bows were the physical transcript of what he stated must occur ; a transcript, moreover, which, compared with his words, was far more complete and impressive than any ever exhibited by the rainbow in Nature. Take another instance. The beautiful rings of colour observed when a point of light is looked at through the seeds oi lycopodium shaken over a piece of glass, or shaken as a cloud in the air, are known to be produced by minute particles all of the same size. The iridescence of clouds seen sometimes in great splendour in the Isle of Wight, but more frequently in the Alps, is due to this equality in the size of the 1 Sec art. ' The Rainbow and its Congeners,' in this volume. THE "WAVE THEOBY. 275 cloud-particles. Now, the smaller the particles, the vider are the coloured rings, and Young devised an instrument, called the Eriometer, which enabled him from the measurement of the rings to infer the size oi the pa: tides. 1 Again, Hitter had discovered the ultra- violet rays of the spectrum, -while Wollaston had noticed the darkening effect produced by these rays when permitted to fall on paper, or leather, which had been dipped in a solution of muriate of silver. Employ- ing these invisible rays to produce invisible Newton's rings, Young projected an image of the rings upon the chemically-prepared paper. He thus obtained a dis- tinct photographic image of the rings. This was one of the earliest experiments wherein a true photographic picture was produced. Young had little notion at the time of the vast expansions which the art of photo- graphy 'vas subsequently to undergo. But Young was not permitted to pursue his great researches in peace. The ' Edinburgh Keview ' had at that time among its chief contributors a young man of vast energy of brain and vast power of sarcasm, without the commensurate sense of responsibility which might have checked and guided his powers. His intellect was not for a moment to be measured with that of Young ; but as a writer appealing to a large class of the public, he was, at that time, an athlete without a rival. He a ''terwards became Lord Chancellor of England. Young, it may be admitted, had given him some annoyance, but his retaliation, if such it were, was out of all pro- p jrtion to Young's offence. Besides, whatever his per- 1 In disorders of the eyes such particles sometimes escape into the humours, and produce vivid colours. The enlargement of the circles, which generally excites terror, is a good sign, as it indicates the increasing smallness of the particles by absorption. 276 THOMAS YOUNG. sonal feelings were, it' was not Young that he assailed so much as those sublime natural truths of which Young at the time was the foremost exponent. Through the undulatory theory he attacked Young without scruple or remorse. He sneered at his position in the Royal Institution, and tried hard to have his papers excluded from the 'Philosophical Transactions.' 'Has the Eoyal Society,' he says, 'degraded its publications into bulletins of new and fashionable theories for the ladies of the Koyal Institution ? Let the Professor continue to amuse his audience with an endless variety of such harmless trifles, but in the name of science let them not find admittance into that venerable repository which con- tains the works of Newton and Boyle and Cavendish and Maskelyne and Herschel.' The profound, compli- cated, and novel researches on which Young was then engaged rendered an occasional change of view neces- sary. How does the reviewer interpret this praise- worthy loyalty to truth ? ' It is difficult,' he says, ' to deal with an author filled with a medium of so fickle and vibratory a nature. Were we to take the trouble of refuting him, he might tell us, " my opinion is changed, and I have abandoned that hypothesis. But here is another for you."' We demand if the world of science which Newton once illuminated is to be as changeable in its modes as the world of fashion, which is directed by the nod of a silly woman or a pampered fop ? We have a right to demand that the hypothesis shall be so consistent with itself aa not to require perpetual mending and patching ; that the child we stoop to play with shall be tolerably healthy, and not of the puny and sickly nature of Dr. Young's productions, which have scarcely stamina to subsist until the fruitful parent has furnished us with a new litter, to make way for which he knocks on the THE WAVE THEORY. 277 head, or more barbarously exposes, the first.* The re- viewer taunts Young with claiming the inheritance of Newton's queries, * vainly imagining that he fulfils this destination by ringing changes on these hypotheses, arguing from them as if they were experiments or de- monstrations, twisting them into a partial coincidence with the clumsy imaginations of his own brain, and pom- pously parading what Newton left as hints in a series of propositions with all the affectation of system.' To Brougham's coarse invective Young replied in a masterly and exhaustive letter. A single copy, and one only, was sold by its publisher. There were at that time in the ranks of science no minds competent to understand the controversy. The poison worked with- out an antidote, and, for thirteen years, Young and his researches on light had no place in public thought. His discoveries remained absolutely unnoticed until their re-discovery byFresnet lifted the pall which for so long a time had been thrown over this splendid genius. Young lectured for two years at the Royal Institu- tion, and he afterwards threw the lectures into a perma- nent form in a quarto volume of 750 pages, with 40 plates, and nearly 600 figures and maps. He also pro- duced at the same time a second volume of the same magnitude, embracing his optical and other memoirs, and a most elaborate classed catalogue of works and papers, accompanied by notes, extracts, and calcula- tions. For this colossal work Young was to receive 1,000. His publisher however became bankrupt, and he never touched the money. His lectures constitute a monument of Young's power almost equal to that of his original memoirs. They are replete with profound reflections and suggestions. In his eighth lecture, on ' Collision,' the term energy, now in such constant use. 278 THOMAS YOUNG was first introduced and defined. By it he was able to avoid, and enable us to avoid, the confusion which had crept into scientific literature by the incautious em- ployment of the word force. Further, the theory now known as the Young-Helmholtz theory, which refers all the sensations of colour to three primary sensations red, green, and violet was clearly enunciated by Young in his thirty-seventh lecture, on * Physical Optics/ His views of the nature of heat were original and correct. He regarded the generation of heat by friction as an unanswerable confutation of the whole doctrine of material caloric. He gave appropriate illustrations of the manner in which he supposed the molecules of bodies to be shaken asunder by heat. 'All these analogies,' he says, 'are certainly favourable to the opinion of the vibratory nature of heat, which has been sufficiently sanctioned by the authority of the greatest philosophers of past times and by the most sober reasoners of the present.' In anticipation of Dr. Weils, Young had observed and recorded the fact, that a cloud passing over a clear sky sometimes causes the almost instantaneous rise of a thermometer placed upon the ground. The cloud he assumed acted as a vesture which threw back the heat of the earth. Eadiant heat and light are here placed in the same category. William Herschel had already shown their kinship, by proving that the most powerful rays of the sun were entirely non-lumi- nous. Subsequent to this, the polarisation of heat, by Principal James Forbes, rendered yeoman service in the propagation of the true faith. Young's essay on the ' Cohesion of Fluids ' is to be ranked amongst the most important and difficult of his labours. It embraced his views and treatment of the subject of capillary attraction. But as this topic is to be treated here next week by a spirit kindred to that of THE WAVE THEORY. 279 Young himself, 1 I may be excused for saying nothing more about it. The essay drew Young into a con- troversy with the illustrious Laplace, in which the Englishman exhibited that scimitar-like sharpness of pen which more than once had drawn him into con- troversy. Young resigned his post at the Koyal Institution, believing that devotion to work alien lo his profession would be sure to injure his prospects as a physician. In the summer of 1802 he visited Paris, and at one of the meetings of the Academy was introduced to the First Consul. In March 1803, he became M.B. of Cam- bridge six years after entering the University while five years more had to elapse before he was able to take the degree of M.D. In June 1804, he married Miss Eliza Maxwell, the daughter of J. P. Maxwell, Esq., of Trippendence, near Farnborough, in Kent. As regards medical practice, Young, to be a popular physician, was probably too cool and cautious in the examination of his data, and trusted too little to the lancet and the calomel invoked in the vigorous prac- tice of his time. After a somewhat strenuous contest he was appointed Physician to St. George's Hospital. The appointment was a strong proof of the esteem in which he was held. His lectures, however, were not so well attended as those of his colleagues, for he lacked the warmth and pliancy which usually commend a lecturer to young men. Young's medical works, em- bodying the results of great labour and research, were received with high consideration and esteem. By the force of his sarcasm and the glamour of his rhetoric, Brougham had succeeded in inflicting a serious, if not an irreparable, wound on the science of hi 1 Sir William Thomson. 280 THOMAS YOUNG. country. After Young's crushing reply, which produced no effect whatever upon the public, the author of that reply was practically forgottten as a factor in the ad- vancement of physical optics. But science has always l>efore her the stimulus of natural problems demanding solution, and after a temporary lull the desire to Know more of the nature of light grew in force. New stars arose in France, while the strenuous industry and ex- perimental discoveries of Brewster did much to hold us in equipoise with the Continent. In Paris, Laplace, Malus, Biot, and Arago were all actively engaged. The first three proceeded strictly on Newtonian lines, and by the memoir of Laplace on Double Refraction all antagonism to the theory of emission was considered to be for ever overthrown. In the ' Quarterly Review,' Young criticised this memoir with sagacity and power, and his criticism remains valid to the present time. In accordance with the principles of the wave theory Huyghens had given a solution of the problem of double refraction in Iceland spar. The solution was opposed to that of Laplace. Dr. Wollaston, a man of the highest scientific culture and the most delicate experi- mental skill, subjected the theory of Huyghens to the severest metrical tests, and his results proved entirely favourable to that theory. Wollaston, however, lacked the boldness which would have made him a commander in those days of scientific strife. He saw opposed to him the names of Newton and Laplace, and in the face of such authority he shrank from closing with the conclusions to which his own experiments so distinctly pointed. We now come to a critical point in the fortunes of the wave theory. I need not again refer to the differ- ence between the motion of a wave and the motions of the particles which constitute a wave. A wave of THE WAVE THEORY. 281 sound, for instance, passing through the air of this room would have a velocity of about 1,100 feet a second, while the particles which constitute the wave, and pro- pagate it at any moment, may only move through in- conceivably small spaces to and fro. Now, in the case of sound, this to-and-fro motion occurs in the direction in which the sound is propagated, and a little reflection will make it clear that no matter how a ray of sound, if we may use the term, is received upon a reflecting surface, it will be reflected equally all round as long as the angle inclosed between the reflecting surface and the ray remains unchanged. In other words, the sound- ray has no sides and no preferences as regards reflec- tion. Now Malus discovered that in certain conditions a beam of light shows such preferences. When caused to impinge upon a plane glass mirror, placed in a cer- tain position, it may be wholly reflected ; whereas when the mirror is placed in the rectangular position it may not be reflected at all. Up to the hour when this discovery was made by Malus ligl't had been supposed to be propagated through ether, exactly as sound is propagated through air. In other words, the direction in which the particles of ether were supposed to vibrate to and fro coincided with tha*; of the ray of light. Those who had pre- viously held the undulatory theory were utterly stag- gered by this new revelation, and their perplexity was shared by Young. He was for a time unable to con- ceive of a medium capable of propagating the impulses of light in a way different from the propagation of the impulses of sound. To ascribe to the light-medium qualities which would enable it to differ in its mecha- nical action from the sound-medium was an idea too bold 1 might indeed say too repugnant to the scien- tific mind to be seriously entertained. Yet, deeply 282 THOMAS YOUNG. pondering the question, Young was at length forced to the conclusion that the vibrations concerned in the pro- pagation of light were executed at right angles to the direction of the ray. By this assumption of transverse vibrations, which removed all difficulty, Young also removed the ether from the class of aeriform bodies, and endowed it with the properties of a semi-solid. Fresnel's memoir on Diffraction, upon which, as already stated, Arago had reported, initiated a lasting friendship between the two illustrious Frenchmen. They subsequently worked together. Fresnel, the more adventurous and powerful spirit of the two, came independently to the same conclusion that Young had previously enunciated. But so daring did the idea of transverse vibrations appear to Arago so inconsistent with every mechanical quality which he could venture to assign to the ether that he refused to allow his name to appear in conjunction with that of Fresnel on the title-page of the memoir in which this heretical doctrine was broached. Still, the heresy has held its ground, and the theory of transverse vibrations, as applied to the luminiferous ether, is now univer- sally entertained. Fresnel died in the fortieth year of his age. Allow me to wind up this section of our labours by reference to a German estimate of Young's genius. ' His mind,' says Helmholtz, ' was one of the most pro- found that the world has ever produced ; but he had the misfortune of being too much in advance of his age. He excited the wonder of his contemporaries, who, how- ever, were unable to rise to the heights at which his daring intellect was accustomed to soar. His most im- portant ideas lay, therefore, buried and forgotten in the folios of the Eoyal Society, until a new generatiou THE WAVE THEORY. 283 gradually and painfully made the same discoveries, proving the truth of his assertions and the exactness of his demonstrations.' NOTE ON ENERGY. The passage in which Young introduces and defines the terra energy is so remarkable that I venture to re- produce it here. ' The term energy may be applied, with great pro- priety, to the product of the mass or weight of a body into the square of the number expressing its velocity. Thus, if a weight of one ounce moves with a velocity ot a foot in a second, we may call its energy 1 ; if a second body of two ounces have a velocity of three feet in a second, its energy will be twice the square of three, or 18. This product has been denominated the living or ascending force, since the height of the body's vertical ascent is in proportion to it ; and some have considered it as the true measure of the quantity of motion ; but although this opinion has been very universally rejected, yet the force thus estimated well deserves a distinct denomination. After the considerations and demonstra- tions which have been premised on the subject of forces, there can be no reasonable doubt with respect to the true measure of motion ; nor can there be much hesita- tion in allowing at once that since the same force, con- tinued for a double time, is known to produce a double velocity, a double force must also produce a double velocity in the same time. Notwithstanding the simpli- city of this view of the subject, Leibnitz, Smeaton, and many others, have chosen to estimate the force of a moving body by the product of its mass into the square of its velocity ; and though we cannot admit that this estimation of force is just, yet it may be allowed that many of the sensible effects of motion, and even the 19 284 THOMAS YOUNO. advantage of any mechanical power, however it may be employed, are usually proportional to this product, or to the weight of the moving body, multiplied by the height from which it must have fallen in order to acquire the given velocity. Thus, a bullet moving with a double velocity will penetrate to a quadruple depth in clay or tallow ; a ball of equal size, but of one-fourth of the weight, moving with a double velocity, will pene- trate to an equal depth ; and, with a smaller quantity of motion, will make an equal excavation in a shorter time. This appears at first sight somewhat paradoxical ; but on the other hand we are to consider the resistance of the clay or tallow as a uniformly retarding force, and it will be obvious that the motion, which it can destroy in a short time, must be less than that which requires a longer time for its destruction. Thus also when the resistance opposed by any body to a force tending to break it is to be overcome, the space through which it may be bent before it breaks being given, as well as the force exerted at every point of that space, the power of any body to break it is proportional to the energy of its motion, or to its weight multiplied by the square of its velocity.' [The foregoing Exsay not prepared with the tiem of giving the members of the Royal Institution some notion of a man regarding whom many of them hnew but little. I tried at the same time to dram -up a brief account of Young's labours on the Hieroglyphics of Egypt.

Young's capacity and acquirements in regard to languages have been already glanced at. As a classical scholar his reputation was very high. His Greek calli- graphy was held to vie in elegance with that of Person. A man so rounded in his culture could hardly be said to have an intellectual bent ; but if he had one, the examina- tion and e'ucidation of ancient manuscripts must have fallen in with it. It is quite possible, however, that, had he not been disheartened by the apparent success of Brougham, he would have clung more steadfastly to physical science. However this may be, we now find him in a new field. In October 1752 the first rolls of the papyri of Herculaneum, wearing the aspect of blackened roots, were discovered in what appeared to be the library of a palace near Portici. They had been covered to a depth of 120 feet with the mixed ashes, sand, and lava of Vesuvius. The inscriptions were for the most part written in Greek, but some of them were in Latin. The leaves were carbonised and hard, being glued together by heat to an almost homogeneous mass. Learned Italians had devoted great labour and ingenuity to the separating of the leaves and the deciphering of the inscriptions. To the credit of the Prince of Wales, afterwards George IV., let it be recorded that he manifested from the first an enlightened, liberal, and truly practical interest in these researches. He wrote to the Neapolitan Government, offering to defray all the expenses of unrolling and deciphering the papyri ; and he sent out Mr. Hayter, a classical scholar of repute, to act as co-director with Rossini in the super- intendence of the work. Mr. Hayter appears to have been unequal to the task committed to him. His trans- 286 THOMAS YOUNO. lations were defective ; the gaps were serious and numerous ; and he finally abandoned the manuscripts when he fled from Naples, with the royal family, on the French invasion in 1806. Some of the rolls, which had been presented to the Prince of Wales, were com- mitted to the care of the Koyal Society, and placed by the Society in the hands of Dr. Young. He spent many months in devising and applying means for the opening of the leaves ; and though only partially successful in this respect, 1 he was able to correct many important errors, and to fill many serious gaps in the work of his predecessors. The 'Quarterly Review' was established in 1809, and Young was intimate with its leading contributors. One of these, George Ellis, ' a man of ardent affections,' had resented, almost as personal to himself, the attacks on Young in the ' Edinburgh Review,' and Young's pen was soon invoked to enrich and adorn the pages of its rival. A great work, the ' Herculanensia,' on the ancient condition of Herculaneum and its neighbourhood, had been published. The review of this work was com- mitted to Young, and his article upon it, embodying his own views and researches, was published in 1810. 'The appearance of the article,' says Peacock, 'equally remarkable for its critical acuteness and vigorous writ- ing, at once placed its author, in the estimation of the public, in the first class of the scholars of the age.' Gifford, the editor of the ' Quarterly,' described the article as ' certainly beyond all praise.' Ellis, at the bame time, wrote thus to Young : ' It is a consolation to know that Brougham, who took advantage of the growing circulation of the ' Edinburgh Review ' to did- 1 Davy afterwards tried his hand upon the rolls, with imperfect luccesa. HIEROGLYPHICAL RESEARCHES. 287 seminate his vile abuse of you ; and Jeffrey, who per- mitted him to do so, should be condemned to hear your praises upon all sides.' The tide had clearly turned in Young's favour, even prior to his final and triumphant vindication by Fresnel. From this time forward in- scriptions of all kinds were sent to Young for discussion or interpretation. They were found in numbers among his papery after his death. 1 It was a mind thus endowed and disciplined that now turned to the formidable but fascinating task of deciphering the hieroglyphics of Egypt. An adum- bration of his researches, which must, under the cir- cumstances, be weak and faint, I will endeavour to bring before you. The famous Rosetta stone was discovered by the French in Egypt in 1799. It bore three inscriptions : 1 ' In the Appendix,' says Young's biographer, ' to Captain Light's Travels in Egypt, Nubia, Palestine, and Cyprus, he furnished translations and restorations of several Greek inscriptions; and when ] '.arrow gave an account in the Quarterly Review of recent researches in Egypt, more especially those of Caviglia on the Great Sphinx, it \v;is from Young that he obtained the restoration of the inscription on the second digit of the great paw.' In the third volume of Young's Works, this inscription, taken from the nineteenth volume of the Quarterly Review, is given, with translations into modern Greek, Latin, and English. The last-mentioned runs thus : Thy form stupendous here the gods have placed, Sparing each spot of harvest-bearing land ; A nd with this mighty work of art have graced A rocky isle, encumber'd once with sand ; And near the Pyramids have bid thee stand : Not that fierce Sphinx that Thebes erewhile laid waste, But great Latona's servant mild and bland ; Watching that prince beloved who fills the throno Of Egypt's plains, and calls the Nile his own. That heavenly monarch [who his foes defies], Like Vulcan powerful [and like Pallas wisej. 1 288 THOMAS YOUNG. the first, Hieroglyphical or sacred; the second, En- chorial ! a name given by Young to the common lan- guage employed by the Egyptians in the time of the Ptolemies ; and the third, Greek. At the end are given the following directions : ' What is here decreed shall be engraved on a block of hard stone, in sacred, in native, and in Greek characters, and placed in each temple of the first and second and third gods.' All three inscriptions were more or less mutilated and effaced when the stone was discovered. Person and Heyne had, however, succeeded in almost completely restoring the Greek one. It had been a custom with Young to pay an annual visit to "Worthing, and to pursue there for a portion of the year his practice as a physician. The Society of Antiquaries had caused copies of the three inscriptions of the Kosetta stone to be made and published. In the summer of 1814 Young took all of them to Worthing, where he sub- jected them to a severe comparative examination. Earon Sylvestre de Sacy, an eminent Orientalist, had discovered in the native Egyptian certain groups of characters answering to proper names, while Aker- blad, a profound Coptic scholar, had not only added to the number, but attempted to establish an alphabet answering to the native Egyptian inscription. Young took up the researches of these distinguished men as far as they could be relied on. Assuming all three in- scriptions to express the same decree, one of them being in a language known to scholars, it was inferred by Young that a strict comparison of line with line, word with word, and character with character, would lead him by the sure method of science from the known to 1 Called in the Greek ' ENCHOKIA GRAMMATA,' or letters of the country. Young deprecates the introduction, afterwards, by Cham- pollion, of the term ' DEMOTIC,' or popular. HIEROGLYPKLCAL KESEAECHE8. 289 the unknown. He rapidly passed his predecessors. De Sacy had determined three proper names in the Egyp- tian; Akerblad nine others, and five or six Coptic- words ; while Young, soon after, detected the rudiments of fifty or sixty Coptic words, which, however, formed but a very small fraction of the whole inscription. Here an unexpected stumbling-block was en- countered. The effort of Akerblad to reduce the whole Enchorial inscription to Coptic had failed, 1 and it soon became evident to Young that every such attempt must of necessity fail. His conviction and its grounds are first mentioned in a letter to Mr. G-urney, written in August 1814. 'I doubt,' he writes, 'if it will be ever possible to reduce much more of it to Coptic, especially as I have fully ascertained that some of the characters are hieroglyphics.' As bearing upon the derivative origin of the Enchorial inscription, the discovery here announced is obviously of the highest importance. Young continues : ' I have, however, made out the sense of the whole sufficiently for my purpose, and, by means of variations from the Greek, I have been able to effect a comparison with the hieroglyphics which it would have been impossible to do satisfactorily without this inter- mediate step.' In a letter to the Archduke John of Austria, dated August 2, 1816, Young announced that he had *now fully demonstrated the hieroglyphical origin ' of the Enchorial inscription. 2 1 Notwithstanding this failure, his name,' says Peacock, ' should ever be held in honour as one of the founders of our knowledge of Egyptian literature, to the investigation of which he brought no Buiall amount of patient labour and philological learning.' * The same discovery,' says the editor of the third volume of Young's Works, ' was announced by M. Champollion, as his own, in his memoir, De VEcrlture Hieratique det Anciens JL'yyjrienft, pub- lished at Grenoble in 1821 This memoir contained several plates in which the hieroglyphic and hieratic characters are corn- 290 THOMAS YOUNG. 4 1 had thought it necessary,' says Young, in an essay written to clear the air on this and various other points some years afterwards, c to make myself in some measure familiar with the remains of the old Egyptian language as they are preserved in the Coptic and The- baic versions of the Scriptures ; and I had hoped, with the assistance of this knowledge, to be able to find an alphabet which would enable me to read the Enchorial inscription, at least into a kindred dialect. . But in the progress of the investigation 'I had gradually been com- pelled to abandon this expectation, and to admit the conviction that no such alphabet would ever be dis- covered, because it had never been in existence. I was led to this conclusion, not only by the un tractable nature of the inscription itself which might have depended on my own want of information and address but still more decidedly by the manifest occurrence of a multitude of characters which were obviously imperfect imitations of the more intelligible pictures that were observable among the distinct hieroglyphics of the first inscrip- tion, such as a priest, a statue, a mattock, or plough, which were evidently, in their primitive state, delinea- tions of the objects intended to be denoted by them, and which were, as evidently, introduced among the Enchorial characters.' Young, as we have seen, had begun his labours on pared, on the same plan as Dr. Young's specimens in the Encycl*- pffdia Britannica, published in 1819. He sent a copy of them to Di Young, but withheld the letterpress. Dr. Young accordingly remained for sever.il years under the impression that this work had been published at a much earlier period. Writing to Sir Williara Gell in 1827 in reference to this point, Young remarks :' I never knew till now how much later his publication was, for he gave it to me without the text." The publication was Champollion's Com- parative Table of Hieroglyphics, ' containing,' says Young, ' what 1 had published in 1816,' five years earlier. niEROGLYPUICAL RESEAECHES. 291 the Rosetta stone in May 1814. In the month of August he was able to announce to Mr. Grurney his discovery that some of the Enchorial characters were hieroglyphics. Prior to Young, no human being had dreamt of the transfer of the characters of the first inscription to the second. The first was pictural and symbolic ; the second, to all appearance, a purely alpha- betical running- hand. It had always been regarded as such. By means of the funeral papyri Young still further established the relationship between the first and second inscriptions. In 1816 he obtained from Mr. William Hamilton a loan of the noble work entitled ' Description de 1'Egypte,' in which were carefully pub- lished several of the papyrus manuscripts. Many of the inscriptions dealt with the same text, and by comparing them one with another Young was able to trace the gradual departure from the original hieroglyphic charac- ters. Probably with a view to more rapid writing, these had passed through various phases of degradation, until they reached the stage corresponding to the Enchorial inscription of the Eosetta stone, ' which,' says Young, 'resembled in its general appearance the most un- picturesque of these manuscripts.' Long before the time of Young, learned men had tried their hands on the Rosetta characters, but no relationship like that here indicated had ever been discerned. Pre-eminent among the Egyptologists of that time was the celebrated Champollion, librarian at Grenoble. In his very first reference to Champollion, Dean Peacock speaks thus of the illustrious Frenchman : He had made the history, the topography, and anti- quities of Egypt, as well as the Coptic language and its kindred dialects, the study of his life, and he started therefore upon this inquiry with advantages that prob- 292 THOMAS YOUNG. ably no other person possessed ; and no one who i acquainted with his later writings can call in doubt his extraordinary sagacity in bringing to bear upon every subject connected with it, not merely the most appo- site, but also the most remote, and sometimes the most unexpected, illustrations.' Thus equipped, however, Champollion made next to no progress before the ad- vent of Young. 'With the exception,' says Peacock, * of the identification of a few additional Coptic words, very ingeniously elicited from the Egyptian text, he made no important advance on what had already been done by Akerblad. Like him, also, he abandoned the task of identifying the hieroglyphical inscription, or portions of it, with those corresponding to them in the Egyptian or Greek text., as altogether hopeless, in con- sequence of the very extensive mutilations which it had undergone.' Young, however, had determined about ninety or one hundred characters of the mutilated hieroglyphic inscription (the funeral papyri enabled him afterwards to more than double the number), and these sufficed to prove, ' first, that many simple objects were repre- sented by their actual delineations ; secondly, that many other objects, represented graphically, were used in a figurative sense only, while a great number of the symbols, in frequent use, could be considered as the pictures of no existing objects whatever ; thirdly, that a dual was denoted by a repetition of the character, but that three characters of the same kind following e.ich other implied an indefinite plurality, mare com- pendiously represented by three lines or bars attached to a single character ; fourthly, that definite numbers were expressed by dashes for units, and arches, either round or square, for tens ; fifthly, that all hieroglyphic inscriptions were read from front to rear, as the ob- HIEKOGLYPHICAL KESEAHCHES. 293 jects naturally follow each other ; sixthly, that proper names were included by the oval ring, or border, or cartouche ; l and seventhly, that the name of Ptolemy alone existed on this pillar, having only been completely identified by help of the analysis of the Enchorial in- scription. And,' adds Young, * as far as I have ever heard or read, not one of these particulars had ever been established and placed on record by any other person, dead or alive.' No man was a better judge of intellectual labour than Dean Peacock. The whole of Young's writings, preparatory and otherwise, were before him when he wrote ; and he states emphatically, that it is impos- sible to estimate, either the vast extent to which Dr. Young had carried his hieroglyphical investigations, or the progress which he had made in them, without an inspection of these manuscripts. In reference to an article entitled * Egypt,' written by Young in 1818, and published in the ' Encyclopaedia Britannica ' for 1819, a writer in the 'Edinburgh Keview' for 1826 delivers the following weighty opinion : ' We do not hesitate to pronounce this article the greatest effort of scholarship and ingenuity of which modern literature can boast.' Even to an outsider it offers proof of astonishing learning and research. Still, Peacock assures us that this publication of 1819 could hardly be considered more than a popular and super- ficial sketch of the vast mass of materials on which it was founded. Young was limited to what Peacock here calls ' a popular and superficial sketch' by the fact that the 1 Young's editor adds here : ' The discovery was long afterwards made by Champollion that the cartouches were confined to tha names of royal personages.' 294 THOMAS YOUNO. article in the ' Encyclopaedia Britannica ' was written for ordinary readers, rather than for critics or learned men. In this article, however, we are allowed a glimpse of Young's mode of collating and comparing the different inscriptions. He looks at the Enchorial inscription, and notices certain recurrent groups of characters ; he looks at the Greek inscription, and finds there words with the same, or approximately the same, periods of recurrence. Thus, ' a small group of characters occurring very often, in almost every line, might be either some termination, or some very com- mon particle ; it must therefore be reserved till it is found in some decisive situation, after some other words have been identified, and it will then easily be shown to mean and. The next remarkable collection of characters is repeated twenty-nine or thirty times in the Enchorial inscription; and we find nothing that occurs so often in the Greek, except the word ki.ng. . . . A fourth assemblage of characters is found fourteen times in the Enchorial inscription, agreeing sufficiently well in frequency with the name of Ptolemy. . . . By a similar comparison, the name of Egypt is iden- tified. . . . Having thus,' says Young, 'obtained a sufficient number of common points of subdivision, we next proceed to write the Greek text over the Encho- rial, in such a manner that the passages ascertained may all coincide as nearly as possible ; and it is ob- vious that the intermediate parts of each inscription will then stand very near to the corresponding passages of the other. . . . By pursuing the comparison of the inscriptions thus arranged, we ultimately discover the signification of the greater part of the individual Enchorial words.' Having thus compared the Greek text with the Enchorial, Young next proceeded to compare the En/ HIEROGLYPHICAL RESEARCHES. 295 chorial with the hieroglyphical. About half the lines of the latter were obliterated, and the rest were con- siderably defaced. Towards the ends, however, both inscriptions were fairly well preserved; and these were the portions subjected to the scrutiny of Young. Making allowance for the differences of space occupied by the two inscriptions, and measuring from the final words of the inscription proportional distances, de- termined by the Enchorial characters for God, King, Priest and Shrine, the meaning of which had been well established, Young sought at the places indicated by these measurements for the corresponding hiero- glyphics. He soon found that Shrine and Priest were denoted by pictures of the things themselves. The other terms, God and King, were still more easily ascertained, from their situation near the name of Ptolemy. Having thus fixed his points of orientation, Young placed them side by side, and subjected the characters lying between them to a searching com- parison. He offers in his article of 1819 the last line of the sacred characters, with the corresponding parts of the other inscriptions, as a 4 fair specimen of the result that has been attained from these operations.' Up to the time of which we now speak, although profoundly learned men had attempted to decipher the funeral papyri of Egypt, if we omit the labours of Young, very little progress had been made in this direction ; while in regard to the decipherment of the hieroglyphics nothing had been done. A vast extension of our knowledge of Egyptian writing is to be ascribed to the following accident. An Italian named Cassati had brought to Paris several manuscripts from Upper Egypt. One was written ex- actly in the Enchorial character of the second inscrip- 296 THOMAS YOUNG. tion on the Rosetta stone. It was a deed of sale, and on the hack of the manuscript was an endorsement in Greek. When in Paris, Young had received from Champollion a tracing of the Enchorial deed, hut not of the Greek endorsement. About the same time, Mr. Grey, an English traveller, brought to England a number of manuscripts, which he placed in the hands of Dr. Young. One of them was written entirely in Greek, and Young immediately perceived that it was a perfect copy of the Enchorial deed of sale. He wrote immediately to Champollion, informing him of the fact, and begging him to send a copy of the Greek endorsement. Champollion did not comply with this request, but his countryman, Raonl Rochette, courteously and promptly responded to Young's application, and sent him a correct copy of the whole Cassati manuscript. The possession of the Greek translation was of course an immense help to Young in his efforts to decipher the Enchorial deed, on which he was at this very time engaged. ' I could not,' he says, 'but con- clude that a most extraordinary chance had brought into my possession a document which was not very likely, in the first place, ever to have existed, still less to have been preserved uninjured for my information through a period of near two thousand years. But that this very extraordinary translation should havo been brought safely to Europe, to England, and to me, at the very moment when it was most of all desirable to me to possess it, as the illustration of an original which I was then studying, but without any reasonable hoj>e of being able to fully comprehend it, this com- Hnation would in other times have been considered as affording evidence of my having become an Egyptian sorcerer.' Grey's manuscript related, not to the sale of a house HIEROGLYPHICAL RESEARCHES. 297 or field, but to portions of the collections and offer- ings made from time to time for the benefit of a certain number of mummies. The persons of whom the mummies were the remains were described at length in bad Greek ; but though bad, a comparison between it and the Enchorial writing gave important informa- tion regarding the orthography of ancient Egypt. Mr. Grey's collection contained three other similar deeds, .11 written in the Enchorial character of the Rosetta stone, and endorsed with the Greek registry. The dates of these documents closely corresponded with that of the Cassati manuscript, which was 146 years before Christ. They refer to the sale of land, the boundaries of which were very clearly defined. 1 In those days, as we know, the Egyptians were the best land-surveyors in the world. The comparison of these documents formed, as might be expected, an epoch in the history of Egyptian literature. 1 And the persons concerned were equally well defined. In this respect the Egyptians might vie with the writers of Continental passports. The following is a translation of the famous papyrus of Anastasy, recording a deed of sale : There was sold by Pamonthes, aged about forty-five, of middle size, dark complexion, and hand- some fignre, bald, round faced, and straight nosed ; by Snachomnens, aged about twenty, of middle size, sallow complexion, likewise round faced and straight nosed ; and by Semmuthis Persinei, aged about twenty-two, of middle size, sallow complexion, round faced, flat nosed, and of quiet demeanour ; and by Tathlyt Persinei, aged alx>nt thirty, of middle size, sallow complexion, round face, and straight nose with their principal Pamonthes a party in the sale; the four being of the children of Petepsais of the leather-cutters ot the Memnonia ; out of the piece of level ground which belongs to them in the southern part of the Memnonia, 8,000 cubits of open field. ... It was bought by Nechntes the less, the son of Asos, aged about forty, of middle size, sallow complexion, cheerful countenance, long face, and straight nose, with a scar upon the middle of his forehead, for C01 pieces of brass, the sellers standing as brokers, and as securities for the validity of the sale. It wai accepted by Nechutes the purchaser. 208 THOMAS YOUNG. We now approach a period of stormy discussion regarding the claims of different discoverers. And as the tempest raged chiefly round Young and Champollion, it is desirable to fix with precision, if that be possible, the position of the learned Frenchman before he came into contact with Young. This a work published by Champollion at Grenoble in 1821 enables us to do. After speaking of the notions previously entertained regard- ing the hieroglyphical and epistolographic characters of the Egyptians, and of the opinion, universally dif- fused, that the Egyptian manuscripts, like those of to- day, are alphabetical, the author states his case thus: 4 Une longue etude, et surtout une comparaison atten- tive des textes hieroglyphiques avec ceux de la seconde espece, regardes comme alphabetiques, nous ont con- duit a une conclusion contraire. II resulte, en effet, de nos rapprochements : 1 Que 1'ecriture des manuscrits egyptiens de la seconde espece (1'hieratique) n'est point alphabe- tique ; 2 Qae ce second systeme n'est qu'une simple modification du systeme hieroglyphique, et n'en differs uniquement que par la forme des signes ; 3 Que cette seconde espece d'ecriture est 1'hiera- tique des auteurs grecs, et doit etre regardee comme une tachygraphie hieroglyphique ; 4 Enfin, que les caracteres hieratiques sont DES SIGNES DB CHOSES, ET NON DES SIGNES DE SONS.' There is no mention here of the name of Young, though he had, many years previously, made known to the world, as the result of his own researches, the first, second, and third of these propositions. Immediately after the publication of this work in 1821, Champollion became acquainted with the ' popular and superficial sketch ' in reality, the transcendently able article of HIEKOGLYPHICAL RESEARCHES. 299 Young published in the ' Encyclopaedia Britanoica ' for 1819. Peacock's analysis of what next occurred is not agreeable reading. Champollion's memoir of 1821 was rapidly suppressed, and soon became so scarce that it has been passed over by almost every author who has written on the subject. In the following year Champollion addressed a letter to M. Dacier, in which, to use the language of Peacock, we suddenly find him pushed forward into the inmost recesses of the sanc- tuary, reached by Young five years before. The plates, moreover, of the suppressed memoir were circulated, without dates and without letterpress. A copy of these plates was given by Champollion to Young, who was left in entire ignorance of the date of publication. * The suppression of a work,' writes Peacock, in strong reproof, ' expressing opinions which its author has sub- sequently found reason to abandon, may sometimes be excused, but rarely altogether justified; but under no circumstances can such a justification be pleaded when the suppression is either designed or calculated to compromise the claims of other persons with re- ference to our own. The memoir in question very clearly showed that, so late as the year 1821, Cham- pollion had made no real progress in removing the mysterious veil which had so long enveloped the ancient literature of Egypt. The article "Egypt," written by Young, had meantime confessedly come under his observation. He saw the errors of his views and suppressed them, without giving due credit to the man who had first struck into the true path.* In reference to an account given by Champollion of the labours of Young, Peacock remarks, * It would be difficult to point out in the history of literature a more flagrant example of the disingenuous sup- 20 800 THOMAS YOUNG. pression of the real facts bearing upon an important discovery.' And yet the Dean of Ely is by no means stingy in his praise of Champollion. It would be unjust, he says, to refuse to Champollion the honour due to his rare skill and sagacity, not merely in the application of a principle already known, but in its rapid exten- sion to a multitude of other cases, so as not merely to point out its character and use, but also to determine the principal elements of a phonetic alphabet. His long-continued studies, Peacock remarks, had fitted him more than any other living man, Young himself hardly excepted, to deal with this subject, 'and the rapidity of his progress, when once fully started on his career of discovery, was worthy of the highest admi- ration.' Peacock, moreover, describes his work as ever memorable in the history of hieroglyphical research, not only from the vast range of knowledge which it displays, but from the clear and lucid order in which it is arranged. ' It was,' he continues, ' singularly un- fortunate that one who possessed so much of his own should have been so much wanting in a proper sense of justice to those who had preceded him in these inves- tigations as materially to lessen his claims to the re- spect and reverence which would otherwise have been most willingly conceded to him.' With regard to the lack of literary candour, thus so strongly commented on, it is of interest to note the views concerning Champollion held by one of his own countrymen. Soon after the researches of Young had begun, an extremely interesting correspondence was established between him and De Sacy. As early as October 1814 Young was able to submit to his cor- respondent a 'conjectural translation' into Latin of the Egyptian Rosetta inscription. He subsequently HIEROGLYPHICAL RESEARCHES. 801 sent him an English translation, the receipt of which is acknowledged by De Sacy in a letter dated Paris, July 20, 1815. The opening paragraph of this letter contains an allusion of considerable historic import- ance: * Outre la traduction latine de 1'inscription egyptienne, que vous m'avez communiquee, j'ai 16911 posterieurement une autre traduction anglaise impri- mee, que je n'ai pas en ce moment sous les yeux, Vayant pretee a M. Champollion sur la demande que son frere m'en a faite d'apres une lettre qu'il m'a dit avoir reQue de vous." 1 In view of the statement of Champollion in a Precis of his researches published in 1824, that he had arrived at results similar to those obtained by Dr. Young without having any knowledge of Young's opinions, the foregoing extract is significant. De Sacy goes on to recognise formally the progress which had been made by Young at the date of the fore- going letter. He asks some questions regarding Young's method, which in certain cases appeared to him enig- matical. The requisite explanations were promptly given by Young. In a labour of the kind here under consideration, that force of genius which we vaguely term intuition must come conspicuously into play ; and it is not always easy for him to whom the exercise of this force is habitual, to make plain to others the nature and results of its action. De Sacy embodies in the letter above quoted some personal remarks which, were it not that their omission would involve a virtual injustice to Young, one would willingly pass over. ' Si j'ai un conseil a vous donner,' writes the Baron, ' c'est de ne pas trop communiquer vos decouvertes a M. Champollion. II se pourrait faire qu'il pretendat ensuite a la priorite. II cherche en plusieurs endroits de son ouvrage a faire croire qu'il a decouvert beaucoup des mots de 1'inscription gyp- *-TAT TIACHCM0 COLLVM ::ANTA BAHARA. 802 THOMAS YOUNG. tieiine de Rossette. J'ai bien peur que ce nesoitld, qu du charlatanisme : j'ajoute me'me que j'ai de forteg raisons de le penser.' The work of Champollion here referred to was entitled 'L'Egypte sous les Pharaons, ou recherches sur la geographic, la religion, la langue, leg ecritures et I'histoire de 1'Eygpte avant 1'invasion de Cambyses.' Two volumes of the work were published in 1814, but it was never completed. In a letter written towards the end of 1 815, Young passes the following judgment upon this book in regard to its relation to the Eosetta inscriptions : ' I have only spent literally five minutes in looking over Champollion, turning, by means of the index, to the parts where he has quoted the inscription of Eosetta. He follows Akerblad blindly, with scarcely any acknow- ledgment. But he certainly has picked out the sense of a few passages in the inscription by means of Aker- blad's investigations ; although in four or five Coptic words which he pretends to have found in it, he is wrong in all but one, and that is a very short and a very obvious one.' Our neighbours, the French, have been always fond, perhaps rightly fond, of national glory, not only in military matters, but also in science and literature. They rallied round Champollion. Even De Sacy, who had previously warned Young against him, eventually joined in the general pa?an. Arago also, who, in regard to the optical discoveries of Young had behaved so honourably, delivered an Eloge of Young, founded, according to Peacock, on the most imperfect and narrow views of the case. In fact, patriotism came into play where cosmopolitanism ought to have been supreme. Arago seeks to make out that Young stands in the same relation to Champollion as Hooke, in regard HIEROGLYPHICAL RESEARCHES. 808 to the doctrine of interferences, stands to Young. This is certainly a bold comparison. Arago himself gives his reasons for entering the controversy, and they are these: ' Que 1'interpretation des hieroglyphes egyptiens est Tune des plus belles deeouvertes de notre siecle ; que Young a lui-meme mele mon nom aux discussions dont elle a ete 1'objet ; qu'examiner enfin, si la France pent pretendre a ce nouveau titre de gloire, c'est agrandir la mission que je remplis en ce moment, c'est faire acte de bon citoyen. Je sais d'avance tout ce qu'on trouvera d'etroit dans ces sentimens; je n'ignore pas que le cosmopolitisme a son beau cote ; mais en verite, de quel nom ne pourrais-je pas le stigmatiser si, lorsque toutes les nations voisiues enumerent avec bonheur les decouvertes de leurs enfans, il m'etait interdit de cher- cher dans cette enceinte memo, parmi des confreres dont je ne me permettrai pas de blesser la modeste, la preuve que la France n'est pas degeneree, qu'elle aussi apporte chaque annee son glorieux contingent dans le vaste depot des connaissances humaines ? ' The Copley medal of the Eojal Society of London was awarded to Arago in 1825, and on November 30 of that year, on handing over the medal to the gentleman deputed to receive it, Sir Humphry Davy, then Presi- dent of the Society, used the following words : * For- tunately science, like that Nature to which it belongs, is neither limited by time nor by space. It belongs to the world, and is of no country and no age.' I do not hesitate to say that I prefer the sentiment of Davy to that of Arago. Still, even in France, Young did not lack defenders. M. de Paravey, Inspecteur de 1'Ecole Royale Polytech- nique, for example, speaking of himself in the third person, makes the following remarks in a letter dated February 1835, six years after Young's death: 'Ily 804 THOMAS YOUNG. admira la science avec laquelle M. le Docteur Young avait retabli la chronologic des Rois d'Egypte, ne com- mencant leur serie qu'a la XVIII dynastie de Manethon, en regardant les series anterieures comme inadmissi- bles ; resultats auxquels des travaux tout differents avaient egalement conduit M. de Paravey : et, en outre, il jugea, et il juge encore, que le premier il entrait d'une maniere plausible et sure dans 1'interpretation des hieroglypb.es, fournissant ainsi a M. Champollion le jeune une clef sans laquelle ce dernier n'aurait jamais pu arriver aux resultats importants et curieux que depuis il a obtenus.' In the same sense, and almost in the same words, writes Sir Gardner Wilkinson, an ardent admirer of Champollion, and his chivalrous defender against the assaults made upon him after his death. After speaking of him as the kindler into a flame of the spark obtained by Young, he continues thus : * Had Champollion been disposed to give more credit to the value and origin- ality of Dr. Young's researches, and to admit that the real discovery of the key to the hieroglyphics, which in his dexterous hand proved so useful in unlocking those treasures, was the result of his [Young's] labours, he would unquestionably have increased his own reputa- tion without making any sacrifice,' Peacock speaks with wondering admiration of the modesty and forbearance which Young invariably showed in regard to Champollion. He complained a little, but he threw no doubt or insinuation upon the Frenchman's honour. He confined himself exclusively to his own published writings, and made no reference to the loads of labour which lay upon his shelves unpub- lished. Peacock complains, and justly complains, of the unfairness of comparing the Champolliou of 1824 HIEROGLYPHICAL RESEARCHES. 805 with the Young of 1816. Young was the initiatory genius. He gave Champollion the key, which he used subsequently with that masterly skill and sagacity which have rendered his name illustrious. But Pea- cock emphatically affirms that Champollion passed over Young's special researches in connection with the papyri of Grey and Cassati; that whatever principle of discovery had been perceived and established or made known, was appropriated without acknowledgment, the dates which would have proved the unquestionable priority of Dr. Young being carefully suppressed. The Dean of Ely obviously felt very sore in regard to the treatment of Dr. Young. * It is not our object,' he says, * to underrate the merits of the great contri- butions which were made by Champollion to our know- ledge of hieroglyphical literature, but to protest against the persevering injustice with which he treated the labours of Dr. Young; and we feel more especially called upon to do so in consequence of finding that an author like Bunsen, occupying so high a position among men of letters, should have supported with the weight of his authority some of the grossest of his mis- representations.' Peacock acknowledges his own obli- gations to the valuable labours of his friend Mr. Leitch; but he also claims to have pursued an independent course by consulting the unpublished documents in his possession, which were unknown even to himself until he was compelled to study them in connection with the publications which had been founded upon them. * It was only,' he says, 'after this perusal that I became fully aware how imperfectly the published writings of Pr. Young represented either the extent or the charac- ter of his researches ; or the real progress he had made in the discovery of phonetic hieroglyphics many years be- fore Champollion had made his appearance in the field.' 806 THOMAS YOUNG. Within the walls of the village church of Farn- borough, Kent, in the family vault of his wife, lie the remains of Thomas Young. On the church wall is a white marble slab with an inscription, the original of which, composed by Mr. Hudson Gurney, stands under Chantrey's medallion of Young in Westminster Abbey. It runs thus : BACHED TO THE MEMORY Off THOMAS YOUNG, M.D., FELLOW AND FOREIGN 6ECBETABY OP THE EOYAt SOCIETY, MEMBER OP THE NATIONAL INSTITUTE OP FKANCE ; A MAN ALIKE EMINENT IN ALMOST EVERY DEPAETMENT OP HUMAN LEABNINO PATIENT OP UNINTERMITTED LABOUR, ENDOWED WITH THE FACULTY OP INTUITIVE PERCEPTION, WHO, BRINGING AN EQUAL MASTEBY TO THE MOST ABSTRUSE INVESTIGATIONS OP LETTERS AND OF SCIENCE, FIIIST ESTABLISHED THE UNDULATORY THEORY OP LIGHT, AND FIEST PENETRATED THE OBSCURITY WHICH HAD VEILED FOB AGES TUB HIEROGLYPHICS OF EGYPT.

LIFE IN THE ALPS* T E AVINGr England in July, and returning in October, Jj I spend three months of every year among the Swiss mountains. Various and striking are the aspects of nature witnessed during these long visits : Sunshine from unclouded skies, dense fog, mountain mist, furious rain and hail, snow so deep that, were not my wife and I thorough children of the hills, and well acquainted with their ways, we should sometimes fear imprisonment in our highland home. We have also our due share of thunder-storms the peals sometimes rolling at safe distances, but sometimes breaking so close to us that we can hear the hiss of the rocks which precedes the deafening crash. A long roll of echoes follows, undulat- ing in loudness, and finally dying away amid the rocky halls of the mountains. This is the state of things so vividly described by Lord Byron : From peak to peak the rattling crags among Leaps the live thunder. As regards thunder-storms, however, we are far better off than our neighbours in Northern Italy, whose hills, acting as lightning-conductors, partially drain the clouds of their electricity before we receive the shots of their ' red artillery.' We can see from our perch the 1 Written for TJie Youth* i Companion, Boston, Mass. With additions. 809 LIFE IS THE ALPS. wonderful thrilling of these Italian thunder-storms, be- yond the great mountain range at the farther side of the valley of the Rhone. At night it is one of the grandest of spectacles. Flash rapidly follows flash, while at times the light bursts simultaneously from different parts of the heavens, every cloud and mountain-top appearing then 'white-listed tli rough the gloom.' At night the eye is far more sensitive than it is by day, the more vivid lightning thrills being then quite dazzling. Mean- while, no sound is heard ; and an observer might be disposed to conclude that the lightning was without thunder Blitz ohne Donner, as the Germans say. Among the southern mountains, however, where the flashes occur, there is one, called the Monte Generoso, on which stands a hotel in telegraphic communication with the lower world. Thither I have telegraphed on various occasions ; and invariably, when the lightning was thrilling silently in the manner just described, I have been informed that a terrific thunderstorm was raging over Northern Italy. 1 From our position here the peals were too far away to be heard. The region where we dwell was chosen by Mrs. Tyndall and myself on account of its surpassing beauty and grandeur. I first made its acquaintance twenty- nine years ago, having previously become familiar with Mont Blanc and its glaciers, and with other glaciers, both in Switzerland and the Tyrol. It is in the Roman Catholic canton of Valais, which, notwithstanding the success of the Reformation in adjoining cantons, has, up to the present day, maintained its ancient religion. 1 These messages once caused the worthy proprietor of the Monte Generoso Hotel to remark that he knew Englishmen to be in- terested in the weather; but that a gentleman at the Bel A\y Deemed positively crazy on the subject. LIFE IN THE ALPS. 809 Here we live on the friendliest terms with both the priests and the people. Switzerland is made up of a number of cantons, which are subdivided into communes, each possessing its own president and council, and making its own locnl laws. The communal laws are, however, subject to the revision of the cantonal government. We live, for in- stance, in the commune of Naters. The sale of the land on which our chalet stands was first agreed to by the vote of the assembled burghers of the commune ; but their vote had to be afterwards ratified by the * high government' of Sion, the chief town of the canton. Naters, the name of the commune, is also the name of its principal village. I had the honour this year of being unanimously elected an honorary burgher of the commune. This. confers upon me -certain rights and privileges not pre- viously enjoyed. I can pasture cows upon the alps a name given by the inhabitants, not to the snow-rapped mountains, but to the grassy slopes stretching far below the snows. I am also entitled to a certain allowance of fuel from the pine-woods. Finally, I can build a chalet on the communal ground. Prizing, however, the good- will of the people more than these material advan- tages, if I at all avail myself of my newly acquired rights and privileges, it will be to a very moderate extent. The well-known Bel Alp Hotel stands some two or three hundred feet below our cottage. The name ' Bel ' is derived from a little hamlet of huts planted in the midst of grassy pastures, or alps, about half an hour distant from the hotel. The ancient name of the alp on which we have built our nest is Lusgeu Alp, and this is the name that we have given to our cottage. I have called it a chalet, but it is by no means one of the 310 LIFE IN THE ALPS. picturesque wooden edifices to which this term is usually applied. It has to bear, at times, the pressure of a mighty mass of snow. The walls are therefore built of stone, and are very thick. I could give you many illustrations of the breakages produced by snow pressure, but one will suffice. Our kitchen chimney rises from the roof near the eave, and the downward pressure of the snow lying on the roof above it was, on two occasions, so great as to shear away the chimney and land it bodily upon the snow-drift underneath. At present a tall pine tree constitutes a strut which will prevent a recurrence of this disaster. When we arrive early we usually find, here and there, heavy residues of snow. Once, indeed, to obtain en- trance to our kitchen we had to cut a staircase of six .steps in the drift at the back of the house. A stream, brawling down the mountain, leaps forth as a cascade thirty paces from our dwelling. We have a cistern beside the stream high enough to command the whole of our cottage. A plentiful water supply for ordinary purposes is always at hand. For drinking purposes there is a spring which bursts, crystal-clear, from the breast of the mountain, a quarter of an hour below us. From this, especially when the flocks and herds are on the alps, the drinking water ought in all cases to be drawn. 1 An hour ago our little cataract * leaped in glory.* It is now gone whither ? I climb to the top of it, and follow upwards the forsaken bed of the stream. In half an hour I hear the sound of water, and soon after- wards come to a point where the bank of the stream is 1 During the lifetime of its late proprietor I succeeded in getting this water introduced into the Bel Alp Hotel. It may be useful to remark that impure drinking water is just as obnoxious in a bedroom as at a table d'hote. LIFE IN THE ALPS. 311 broken down, and a barrier of clods built across it, all its water being thus diverted into another channel. The streams are a valuable part of the peasant's property ; they are employed to water the sloping meadows, and the laws regulating the distribution of the water are very strict. A burgher has a right to the use of a stream for a certain number of hours. If he exceeds that number he trespasses on his neighbours' rights, and is punished if found out. Now the hotel needs water; and in droughty weather a struggle is carried on between the hotel and the meadows, during which the supply of the former is not unfrequently cut off. Such was the case this morning. When the supply ceases the cause is known, and a peasant provided with pick, spade, or shovel, climbs the mountain and restores the deflected stream. Within doors we work on the ground floor and sleep aloft. We have two bedrooms there and a servants' bedroom, all lined with smooth pine. The house is covered with pine shingle, prettily cut. Slates, I con- sidered, would be a discord in the landscape, and the right of any man to desecrate a scene of natural beauty by such discord may be questioned. We are sometimes wrapped round by absolutely silent air ; more frequently by air in motion, rising sometimes, as already indicated, to the force and sound of raging storms. Over us sail heav}-laden clouds which shower their rain-drops like loud-sounding pellets on the shingly roof. ' The music of the rain' at night is often soothing to a wakeful brain. I walk at times on our terrace under the stars, and trace among them with a clearness not seen else- where the whiteness of the * Milky Way.' Just now the moon is full, gleaming from the glacier, and throw- ing her light, like a holy robe, over the mountains. We sometimes quit our Swiss home regretfully, with 312 LIFE IN THE ALPS. a warm rin shining on the newly-fallen snow, which vastly enhances the loveliness of the scenes around us. We moreover regret bidding good-bye to the gorgeous colouring of the trees arid undergrowth, which might- bear comparison with the beauty of the foliage that I have seen in autumn in the neighbourhood of your OWD Boston. I have never forgotten the autumn splendout of Mr. "Winthrop's trees at Brookline. Sometimes, however, we depart under difficulties. Last year, for example, on October 16, our porters hoisted on their backs the luggage intended for home, and through a dense fog, with the snow three feet deep, and still heavily falling, we moved downwards. Fog on the mountains is terribly bewildering ; and as we descended, one of our men, who had tramped the neighbourhood from his infancy, and had on that ac- count been chosen for our leader, stopped short, and declared that he did not know which way to proceed. There was no danger, but the difficulty was considerable. A thousand feet or so lower down we got entirely clear of the snow. Towards the end of June the flocks and herds are driven to the upper pastures, private ownership ceasing and communal rights, as to grazing, beginning at an elevation of about four thousand feet above the Rhone, or seven thousand feet above the sea. The peasants and their families accompany their living property, re- maining for two or three months in huts built expressly with a view to their annual migration. Nearly the whole of them move into Naters for the winter ; but wo remain alone, amid the solemn silence of the hills, three weeks or a month after the peasants. have disappeared. Their time of disappearance depends upon the exhaus- tion of the pasturage. Many of them have intermediate but." and bits of land between Naters and their highest LIFE IN THE ALPS. 313 dwellings. The possessors of such huts descend by suc- cessive steps to the valley. Snow falls, of course, for the most part, in winter ; but the exact period at which it falls is not to be pre- dicted. A winter may pass with scarcely any snow, while in early spring it may fall in immense quantities. Then follows a time of avalanches, when the snow, de- taching itself from the steep mountain-sides, shoots downwards with destructive energy. I have seen here, in midsummer, snow so heavy that the herds had to be driven a long way down to get a little pasture. Three or four years ago, a fall of un- equalled severity began on the night of September 12. There was a brief respite of sunshine, during which the peasants, had they been wise, might have brought down their flocks. But they failed to do so. Snowing re- commenced, the sheep were caught upon the mountains, and for a long time they could not be reached by their owners. Parties of men, fourteen or fifteen in number, at length ascended in search of the sheep. My wife and I trudged after one party, and extremely hard work we found it to do so. The leader first broke ground, floundering and ploughing a deep channel in the snow. He was soon exhausted, and fell back, while a fresh man came to the front. Each of them thus took the post of leader in his turn. At a considerable elevation we parted company with the men. It was a sombre, sunless afternoon, and the scene was desolate in the extreme. Here and there we could discern groups of men, two or three in number, engnged in skinning the dead sheep they had discovered. A joint of meat would have remained sweet for any length of time in the snow, but the warmth preserved by the fleece caused the flesh of the sheep to putrefy. For thirteen days the chief portion of the flock 314 LIFE IN THE ALPS. remained unaccounted for. During all this time the animals were without food, and, indeed, were given up for lost. Nearly two hundred of them, however, were afterwards driven down to the Bel Alp alive. I saw them arrive after their long fast, and they seemed per- fectly brisk and cheerful. Some of them were entirely hare of wool, the covering having been eaten off their backs by their famishing companions. I have been, assured that the sheep which indulged in this nutriment all died, balls of undigested wool being found in their stomachs afterwards. Avalanches were frequent at the time here referred to, and by them numbers of sheep on the lower slopes were swept away. It is only those burghers who are comparatively well off that ascend to the higher grazing grounds. Even they seem to find the struggle for existence a hard one. Two or three cows and a few sheep or goats constitute, in well-to-do cases, the burgher's movable wealth, while the land privately owned is divided into very small parcels. The peasants' huts, built, for the most part, of pine- logn, richly coloured by the oxidising action of the sun, are not always as wholesome as they might be. The upper part of every hut is divided into two dwelling- rooms, one for sleeping, and the other for cooking and other purposes. The single sleeping-room is sometimes occupied by a numerous family, space being obtained by placing one bed above another, like the bertha in a ship. There is no chimney, the smoke escaping through apertures in the roof. In our neighbourhood, the roofs are usually formed of flags obtained from a rock capable of cleavage. The sleeping-room is always over the cowshed, this position being chosen for the sake of warmth. Through chinks in the floor, the sleepers not only obtain warmth. LIFE IN THE ALPS. 315 but often air which has passed through the lungs of the animals underneath. The result, as regards health, is not satisfactory, the women and children suffering most. Were it not that the contaminated respiration of the night is neutralised by outdoor life during the flay, the result would be still less satisfactory. Thanks to a liberal London chemist, I am provided, from time to time, with simple medicines for those re- quiring medical treatment, and with plaisters for those requiring surgeon's aid. Thanks also to the physicians who visit the Bel Alp Hotel, I am sometimes able to apply these remedies with specially good effect. In the absence of a qualified doctor I do the best I can myself. The peasants come to me in considerable num- bers, while I frequently go to them. I do my best to induce the people to open the win- dows of their sleeping-rooms during the day. The advice is, in many cases, attended to ; while, even where it is neglected, whenever I am seen approaching a hut containing a patient, the windows are thrown open. Justice, firmness, and kindness suffice to make people accept an almost despotic rule ; and this, in my own small way, 1 find to be true of my Alpine neighbours. As I write, a rush, followed by a heavy thud, informs me that a mass of snow has shot from the southern slope of our roof down upon our terrace. The rush is one of a series, brought down by the strong morning gun. This reminds me to tell you something more about the avalanches which are such frequent destroyers of life in the Alps. Whole villages, imprudently situ- ated, are from time to time overwhelmed. We had an eye to this danger when we chose the rocky prominence on which our cottage is built. Climbers and their guides are not unfrequently 21 316 LIFE IN THE ALPS. carried away by avalanches, and many a brave man lies at the present moment undiscovered in their debris. Some years ago, a famous guide, and favourite com- panion of mine, allowed himself to be persuaded to at- tempt the ascent of a mountain which he considered unsafe, and lost his life in consequence. On the slope of this mountain, with the summit fully in view, a report resembling a pistol shot was heard by the party. It was the cracking of the snow. My friend observed the crack, and saw it widen. Tossing his arms in the air he exclaimed, ' We are all lost ! ' The fatal rush fol- lowed in a moment, and my noble guide, with a Russian gentleman to whom he was roped, were dug, dead, out of the snow some days afterwards. The other members of the party escaped. I will now describe to you an adventure of my own on one of these avalanches. Five of us, tied together by a rope, were descending a steep slope of ice, covered by a layer of snow, which is always a position of danger. Through inadvertence the snow was detached, an avalanche was formed, and, on it, all five of us were carried down at a furious pace. We were shot over crevasses, and violently tossed about by the inequalities of the surface. The length of the slope down which we rushed in this fashion was about a thousand feet. It was a very grave accident, and within a hair's breadth of being a very calamitous one. A small gold watch, which I then carried, was jerked out of my pocketj and, when we stopped, I found a fragment of the watch- chain hanging around my neck. I made an excursion into Italy, returned after an absence of nearly three weeks, and, half jestingly, organised a party to go in search of the watch. The proverbial needle in a bundle of straw seemed hardly more hopeless as an object of discovery ; still, I thought LIFE IN THE ALPS. 317 it barely possible that the snow which covered the watch might, during my absence, have sufficiently melted away to bring the watch to the surface. An ascent of some hours brought us to the scene of our impetuous glissade, and soon afterwards, to our sur- prise and delight, the watch was found on the surface of the snow. Its case must have fitted water-tight, for on being wound up it began to tick immediately. It is now in the possession of my godson. Falling stones constitute another serious, and fre- quently fatal, danger in the Alps. And here the goats, which roam about the upper slopes and gullies, often play a mischievous part. An incident of this kind, witnessed by myself, occurred many years ago about mid- way between Chamounix and the Montanvert. I was accompanied at the time by a friend and his son. A herd of goats was observed browsing on the heights above us. Their 'appearance suggested caution. Sud- denly an ominous tapping was heard overhead, and, looking up, I saw a stone in the air. Whenever it touched the rock-strewn ground it was deflected, so that from the direction of the stone at any moment it was difficult to infer its final direction. I called out to my friend, ' Beware of the stone I ' and he, turning towards his son, repeated the warning. It had scarcely quitted his lips, when the missile plunged down upon himself. He fell with a shout, and I was instantly at his side. The stone had struck the calf of his leg, embedding one of its angles in the flesh, and inflicting a very ugly wound. By good fortune, a spring of pure water was at hand ; a wet compress was rapidly prepared, and the wound was bandaged. Then, hurrying down to Chamounix, which was some two thousand feet below us, I brought 318 LIFE IN THE ALPS. up men and means, to carry the patient to his hotel. Perfect quiet would have soon set everything right, but the premature motion of the limb was succeeded by inflammation and other serious consequences. Slipping in perilous places is the most fruitful cause of Alpine disaster. It is usual for climbers to rope themselves together, and the English Alpine dub has taken every pains to produce ropes of the soundest material and the best workmanship. The rope is tied around the waist, or is fastened to a belt clasping the waist, of the climber. The rope is an indispensable accompaniment of Alpine climbing, and no competent mountaineer will recommend its abandonment. Pru- dence, however, is necessary in the use of it. The men tied together ought to be few in number. A party of three or four, including the guide, or guides, is in my opinion large enough. In a numerous party, there is a temptation to distribute responsibility, each indi- vidual tending to rely too much upon the others ; while, in a small party, the mind of each man is more con- centrated on the precautions necessary for safety. Besides this, we have the terrible enhancement of the calamity when the slipping of a single individual carries a number of others to destruction. It was a slip by whom we know not that caused the disaster on the Matterhorn which so profoundly stirred the public mind some years ago. On that occasion, one of the foremost guides of the Alps, and one of the best gentle- men climbers, lost their lives, in company with two younger colleagues. The fearful disaster on the Jungfrau this year was, doubtless, due to the same cause. Six strong climbers, all natives of Switzerland, succeeded, without guides, in scaling the mountain from the northern side. From the summit they attempted to descend the southern slope, LIFE IN THE ALPS. 319 the danger of which varies with the condition of the snow or ice. I had frequently wondered that no accident had ever previously occurred here ; for, to an experienced eye, the possibility of a fatal accident was plain enough- On this slope the six climbers met their doom. They were roped together, and probably only one of them slipped ; but his slip involved the destruction of them all. A few weeks after its occurrence I inspected the scene of the disaster, saw the rocks down which the men had fallen, and the snowfield on which their bodies were found. Their reaching the summit without guides proved them to be competent men. But they could hardly have accomplished the ascent without fatigue, and tired men sometimes shrink from the labour of hewing safe steps in obdurate ice. Neglect on this score may have been the cause of the accident. But this is mere sur- mise, the only thing certain being the mournful fact that on the Jungfrau, this year, six men in the very prime of life went simultaneously to destruction. On the fine October morning when these lines are written, we find ourselves surrounded everywhere by glittering snow. The riven Aletsch glacier and its flanking mountains are dazzling in their whiteness. After a period of superb weather, streaks and wisps of boding cloud made their appearance a few days ago. They spread, became denser, and finally discharged themselves in a heavy fall of snow. But the sunshine rapidly recovered its ascendency, and the peasants, who had already descended some distance with their cows nnd sheep, hoped that two days of such warmth would again clear their pastures. They were deceived, for through the whole of yester- day the snow fell steadily. It interrupted the transport of our firewood, on mules' backs, from the pine woodi 320 LIFE IN THE ALPS. nearly one thousand feet below us. This morning, how- ever, I opened the glass door of our little sitting-room, which faces south, and stepped out upon our terrace. The scene was unspeakably grand. To the right rose the peak of the Weisshorn, the most perfect embodi- ment of Alpine majesty, purity, and grace. Next came the grim Matterhorn, then the noble Mischabel- horner, surmounted by the 'Dom.' Eight opposite rose the Fletschhorn, a rugged, honest-looking mass, of true mountain mould; while to the left of Napoleon's road over the Simplon Pass stretched the snow-ridge of the Monte Leone which, no doubt, derives its name from its resemblance to a couchant lion. Soft gleaming clouds wrapped themselves at times grandly round the mountains, revealing and concealing, as they shifted, melted, or were re-created, the snow-capped peaks. About one thousand five hundred feet below us the white covering came to an end, while, beyond this, sunny green pastures descended to the valley of the Rhone. From the chimneys of our cottage, a light wind carried the smoke in a south-westerly direction ; the clouds, just referred to, being, therefore, to leeward, and not in ' the wind's eye,' did not portend bad weather. To the north, the peaks grouped themselves round the massive Aletschhorn, the second in height among these Oberland Mountains. Over the Aletschhorn the sky was clear, which is one of the surest signs of fine weather. Once, on a morning as fair and exhila- rating as the present one, but earlier in the year, Mrs. Tyndall and myself, from the top of the Aletschhorn a height of fourteen thousand feet looked down upon the summit of the Jungfrau. The general aspects of the Alpine atmosphere, and, more especially, the forms and distribution of the LIFE IN THE ALPS. 321 clouds, are very different in autumn from what they are in early summer. The grandest effects of our moun- tains are, indeed, displayed when no tourist is here to look at them. To us, who remain, this is not a disad- vantage ; for, like the poet's l rapture on a lonely shore,' there is rapture for the lover of Nature in the lonely mountains, and 'a radiance of wisdom in their pine woods.' I well remember, after the tourist season at Niagara Falls had ended, my deep delight in visiting alone the weird region of the ' Whirlpool.' Your countryman, Thoreau, did not love the wilds more than I do. " One striking feature invariably reveals itself here at the end of September and the beginning of October. From the terrace of our cottage we look down upon a basin vast and grand, at the bottom of which stands the town of Brieg. Over Brieg, the line of vision carries us to the Simplon Pass, and the mountains right and left of it. Naters stands in a great gap of the mountains, while meadows and pine-clad knolls stretch, with great variety of contour, up to the higher Alpine pastures. The basin has no regularly rounded rim, but runs into irregular bays and estuaries, continuous with the great valley of the Rhone. At the period referred to, valley, basin, bays, and estuaries are frequently filled by a cloud, the upper sur- face of which seems, at times, as level as the unruffled surface of the ocean. A night or two ago I looked down upon such a sea of cloud, as it gleamed in the light of a brilliant moon. Above the shining sea rose the solsmn mountains, overarched by the star-gemmed sky. Here your young imaginations must aid me, for my pen fails to pursue any further the description of the scene. As I write, on a day subsequent to that already mentioned, a firmament of undimmed azure shuts out 322 LIFE IN THE ALP& the view into stellar space. No trace of cloud is visible j and yet the substance from which clouds are made is, at this moment, mixed copiously with the transparent air. That substance is the vapour of water ; and I take this beautiful day as an illustration, to impress upon you the fact that water-vapour is not a thing that can be seen in the air. Were the atmosphere above and around me at the present moment suddenly chilled, visible clouds would be formed by the precipitation of vapour now invisible. Some years ago, I stood upon the roof of the great cathedral of Milan. The air over the plains of Lom- bardy was then as pure and transparent as it is here to-dav. From the cathedral roof the snowy Alps are to be seen ; and on the occasion to which I refer, a light wind blew towards them. When this air, so pure and transparent as long as the sunny plains of Lombardy were underneath to warm it, reached the cold Alps, and was tilted up their sides, the aqueous vapour it con- tained was precipitated into clouds of scowling black- ness, laden with suow. If you pour cold water into a tumbler on a fine summer day, a dimness will be immediately produced by the conversion into water, on the outside surface of the glass, of the aqueous vapour of the surrounding air. Pushing the experiment still further, you may fill a suitable vessel with a mixture of ice and salt, which is colder than the coldest water. On the hot- test day in summer, a thick fur of hoar frost ia thus readily produced on the chilled surface of the vessel. The quantity of vapour which the atmosphere con- tains varies from day to day. In England, north- easterly winds bring us dry air, because the wind, before reaching us, has passed over vast distances of dry LIFE IN THE ALPS. 323 land. South-westerly winds, on the other hand, come charged with the vapour contracted during their pass-age over vast tracts of ocean. Such winds, in England, produce the heaviest rains. And now we approach a question of very great in- terest. The condensed vapour which reaches the low- lands as rain, falls usually upon the summits as snow. To a resident among the Alps it is interesting to ob- serve, the morning after a night's heavy rain, a limit sharply drawn at the same level along the sides of the mountains, above which they are covered with snow, while below it no snow is to be seen. This limit marks the passage from snow to rain. To the mountain snow all the glaciers of the Alps owe their existence. By ordinary mechanical pressure snow can be converted into solid ice ; and, partly by its own pressure, partly by the freezing of infiltrated water, the snow of the mountains is converted into the ice of the glaciers. The great glaciers, such as the one now below me, have all large gathering grounds, great basins or branches where the snow collects and becomes gra- dually compacted to ice. Partly by the yielding of its own mass, and partly by sliding over its bed, this ice moves downwards into a trunk valley, where it forms what De Saussure called 'a glacier of the first order.' Such a glacier resembles a river with its tributaries. We may go further and affirm, with a distinguished writer on this subject, that ' between a glacier and a river there is a resemblance so complete, that it would be impossible to find, in the one, a peculiarity of motion which does not exist in the other.' Thus, it has been proved that owing to the friction of its sides which holds the ice back, the motion of a 324 LIFE IN THE ALPS. glacier is swiftest at its centre ; that because of the friction against its bed, the surface of a glacier moves more rapidly than its bottom; that when the valley through which the glacier moves is not straight, but curved, the point of swiftest motion is shifted from its centre towards the concave side of the valley. Wide glaciers, moreover, are sometimes forced through narrow gorges, after which they widen again. At some distance below the spot where I now write is the gorge of the Massa through which, in former ages, the great Aletsch glacier was forced to pass, widening afterwards, and over- spreading a large tract of country in its descent to the valley of the Ehone. All these facts hold equally good for a river. On summer days of cloudless glory, the air is some- times still, and the heat relaxing upon the mountains. The glacier is then in the highest degree exhilarating. Down it constantly rolls a torrent of dry tonic air, which forms part of a great current of circulation. From the heated valleys the light air rises, and coming into contact with the higher snows, is by them chilled and rendered heavier. This enables it to play the part of a cataract, and to roll down the glacier to the valley from which it was originally lifted by the sun. But the action of the sun upon the ice itself is still more impressive. Everywhere around you is heard the hum of streams. Down the melting ice-slopes water trickles to feed little streamlets at their bases. These meet and form larger streams, which again, by their union, form rivulets larger still. Water of exquisite purity thus flows through channels flanked with azure crystal. The water, as if rejoicing in its liberty, rushes along in rapids and tumbles in sounding cascades over cliffs of ice. The streams pass under frozen arches and are spanned here and there by slabs of rock which, acting LIFE IN THE ALPS. 325 as natural bridges, render the crossing of the torrent easy from side to side. Sooner or later these torrents plunge with a thunderous sound into clefts or shafts, the latter bearing the name of moulins or mills, and thus reach the bottom of the glacier. Here the river produced by the melting of the surface-ice rushes on unseen, coming to the light of day as the Khone, or the Massa, or the Visp, or the Rhine, at the end of the glacier. A small dark-coloured stone sinks into the ice, while a large stone protects the ice beneath it. Through the small stone the heat readily passes by conduction to its lower surface and melts the ice underneath ; while the barrier offered by the large stone to the passage of the heat cannot be overcome. Round the large stone, therefore, the exposed ice melts away, leaving the rock supported upon a stalk or pillar of protected ice. Slabs of granite, having a surface of one hundred or two hundred square feet, are to be found at this moment poised upon pillars of ice on the Ober Aletsch glacier. Some of them are nearly horizontal. They are called ' tables,' and right royal tables they are for those privileged to feast upon them. Sand strewn upon the glacier by the streams also protects the ice. The protected parts, being left behind, like the ' tables,' form what are called the ' sand cones ' of the glacier. On the adjacent glacier there are cones from ten to twenty feet in height, and they sometimes reach an even greater elevation. On first seeing them, you would imagine them to be heaps of pure sand. But a stroke of the ice-axe shows the sand to be merely the superficial covering of a cone of specially hard ice. The medial moraine, which stretches like a great flexile serpent along the centre of the glacier now below me, 326 LIFE IN THE ALPS. also protects the ice, causing it to rise as a spine which attains in some places a height of fifty feet above the surface of the glacier. It is easy to understand that with a substance like glacier ice, when some parts of it are held back by friction, while other parts tend to move forward, strains must occur which will crack and tear the ice, forming clefts or fissures, to relieve the strains. The crevassea of glaciers are thus produced. And here we have another conspicuous danger of the Alps. Crevasses have been the graves of many a gallant mountaineer. They are especially dangerous when concealed by roofs of snow, which is frequently the case in the higher portions of the glacier. Of this danger my own experience furnishes examples not to be forgotten. Passing them by, I may mention that, during the present year, an esteemed English clergy- man was lost upon an easy glacier of the Engadine, through the yielding of a snow bridge over which h~e was passing. The crevasse into which he fell could not have been deep, as he was able to converse with a com- panion above, and to make the tapping of his ice-axe heard. He did not, as far as I know, complain of being hurt, but desired his companion to hasten to procure a rope. The distance to be passed over, how- ever, before the rope and the necessary help could be obtained, was considerable ; and when rope and help arrived, the clergyman was dead. A discussion followed in the newspapers as to the amount of blame to be assigned to the gentleman who went for the rope. It was said by one writer that he ought to have tied his clothes together, and, by their aid, to have drawn up his friend. The reader of Mr. Laurence Oliphant's last remarkable volume will re LIFE IN THE ALP& 327 member that Mr. Oliphant was once lifted from a dangerous position by a device of this kind. I never lifted a man out of a crevasse by a rope of clothes, but the lost guide to whom I have already re- ferred, and myself, were once let down by such a rope into a chasm, from which, by means of a real rope, which had been entombed with himself, we rescued a fellow-traveller. Even with the best of ropes, it would require a very strong single man above, and an ex- tremely expert ice-man below, to effect a rescue from a crevasse of any depth. In most cases it would be impos- sible. So that I think but little blame was incurred by the omission of the clothes-rope experiment. If a doubt be at all permitted, it must, I think, be on the ground that, having found rescuers, the gentleman failed to accompany them back to the glacier. He pleaded exhaustion, and it is a valid plea. With wider knowledge, however, he might, perhaps, have had himself carried to the glacier rather than remain behind. To a person dying of cold time is everything; and time may have been lost by the guides in finding the particular crevasse in which the unhappy traveller was entombed. The survivor, however, may have been able to describe with accuracy the position of the fissure. If so, he was in my opinion blameless. Taking its whole tenor into account, the title of this article, instead of being ' Life in the Alps,' might perhaps, with more appropriateness, have been * Life and Death in the Alps.' SUPPLEMENT, 1890. There remain two little points the first of which I have not seen noticed elsewhere which I should like, be- fore we part, to mention to my * young companion.'

K Saiasin, of Genera, and myself, bad the good fMtme to witnes a laie and beantiful phenomenoo. The son was doping to the west, and the ^auVy below us, m which lies the great AletsA gtatiet, was filled by a dense Cog. Standing in a position, with the aim behind us, we saw, swept through the Big in front of us, a grand colourless aieh of fight. It occupied a position dose to that which an onfinarj coloured xain- bow might have ou.upif.ri. Twice in Fnghwi^ and twice only, I have seen this fnrwJgi'Bd Hnni^'riin %mri the firet time, in company with my wife, on the high mooriand of Hud Head. The white how WAS first de- scribed by the S^antth navigator, (TUUaa, after whom it is named. Its explanation can only be briefly in- dicated -here. JUong with the true rainbow, and within it, there are usually produced m nnatbur of ether bows, by what Dr. Young named the * interference of light,' They are called supernumerary bows. When the ila drops are all of the same siae, and exceedingly small, 830 LIFE IN THE ALPS. the colours of these bows expand and overlap each other, producing by their mixture the uncoloured white bow. We sometimes hear of ' fog bows,' but it may be doubted whether true impalpable fog can produce a bow. At all events, we may have very dense fogs with all the conditions of light necessary for producing the bow y without its appearance. A sensible drizzle must be mixed with the fog when the bow is produced. On the occasion to which I have referred, my friend and I noticed another singular phenomenon, which is usually known as the * Spectre of the Brocken.' The Brocken, or Blocksberg, is a mountain in Germany rendered famous by the poet Goethe. As I stood with my back to the sinking sun, my shadow was cast on the fog before me. It was surrounded by a coloured halo. When I stood beside my friend, our shadows were seen with an iridescent fringe. We shook our heads ; the shadows did the same. We raised our arms and thrust our ice-axes upwards ; the shadows did the same. All our motions, indeed, were imitated by the shadows. They appeared like gigantic spectres in the mist, thus justifying the name by which they are usually known. The combination of the Brocken spectre and white bow constituted a most striking phenomenon. 1889. ABOUT COMMON WATER* WE have already spent what I trust has proved to you an agreeable and instructive half-hour over water in its solid form. We have conversed about the behaviour of those vast collections of ice which go by the name of glaciers, tracing them to their origin in mountain snow. Closely compacted, but still retain- ing a certain power of motion, the snow passes from the mountain-slopes and reservoirs where it was first collected into the valleys, through which, becoming more and more compacted, it moves as a river of ice. From the end of this solid river always rushes a liquid one, rendered turbid by the fine matter ground from the rocks during the descent of the glacier. An effect which I thought remarkable when I first saw it may be worth mentioning here. Thirty-two years ago I followed the river Khone to the place where it enters the Lake of Geneva. The water of the lake is known to be beautifully blue, and I fancied beforehand that the admixture of the water of the Rhone must infal- libly render the lake turbid. To my surprise, there was no turbidity observable. A moment's reflection rendered the reason of this obvious. The Rhone water, rushing from its parent glaciers, was colder, and there- fore heavier, than the water of the lake. Instead of mixing with the latter, it sank beneath it, disposing of itself along the bottom of the lake, and leaving the surface-water with its delicate azure unimpaired. I propose now to talk to you for half an hour about 1 Written for The Youth's Companion. 22 832 ABOUT COMMON WATER. water in its more common and domestic forms. On the importance of water it is not necessary to dwell, for it is obvious that upon its presence depends the lifu of the world. As an article of human diet, its impor- tance is enormous. Not to speak of fruits and vege- tables, and confining ourselves to flesh, every four ])ounds of boneless meat purchased at the butcher's shop contain about three pounds of water. I remember Mr. Carlyle once describing an author, who was making a great stir at the time, as ' a weak, watery, insipid creature.' But, in a literal and physical sense, we are nil ' watery.' The muscles of a man weighing one hun- dred and fifty pounds weigh, when moist, sixty-four pounds, but of these nearly fifty pounds are mere water. It is not, however, of the water compacted in the muscles and tissues of a man that I am now going to speak, but of the ordinary water which we see every- where around us. Whence comes our drinking-water ? A little reflection might enable you to reply : 'If you go back far enough you will find that it comes from the clouds, which send their rain down upon the earth.' 'But how,' it may be asked, 'does the water get up into the cloud region ? ' Your reply will probably be, ' It is carried up by evaporation from the waters of the earth.' A great Roman philosopher and poet, named Lucre- tius, wrote much about atoms, which he called 'the First Beginnings.' When it was objected that nobody could see the atoms, he reasoned in this way : ' Hang out a wet towel in the sun, and after some time you will find that all the water has gone away. But you cannot see the particles of the water that has thus dis- appeared. Still, it is perfectly certain that the water which, when put into the towel, could be seen, and felt, ABOUT COMMON WATER. 883 and tasted, and weighed, must have escaped from the towel in this invisible way. How, then, can you ex- pect me to show you the atoms, which, as they are the first beginnings of things, are probably much smaller than your " invisible " particles of water ? * In this invisible state, to which water may be re duced, it is called aqueous vapour. Let it then be admitted that water rises into the air by evaporation ; and that in the air it forms the clouds which discharge themselves upon us as rain, hail, and snow. If you look for the source of any great American river, you will find it in some mountain-land, where, in its infancy, it is a mere stream. Added to, gradually, by other tributary streams, it becomes broader and deeper, until finally it reaches the noble magnitude of the Mississippi or the Ohio. A consider- able portion of the rain-water sinks into the earth, trickles through its pores and fissures, coming here and there to light as a pellucid spring. We have now to consider how 'spring- water' is affected by the rocks, or gravel, or sand, or soil, through which it passes. The youths who choose this journal for a 'com- panion ' know already that Mrs. Tyndall and myself are lovers of the highlands. I tried last year to give them some notion of ' Life in the Alps.' Well, here in Eng- land, Alpine heights are not attainable ; but we have built our house upon the highest available land within two hours' of London. Thousands of acres of heather surround us, and storms visit us more furious than those of the Alps. The reason is, that we are here on the very top of Hind Head, where the wind can sweep over us without impediment. There is no land above our house, and therefore there are no springs at hand available for our use. But lower down, in the valleys, the springs burst forth, 834 ABOUT COMMON WATER. providing the people who live near them with the brightest and purest water. These happy people have all my land, and all the high surrounding land, as a collecting-ground, on which the rain falls, and from which it trickles through the body of the hill, to appear at lower levels. What, then, am I obliged to do? It stands to reason that if I could bore down to a depth lower than the springs, the water, instead of flowing to them, would come to me. This is what I have done. I have sunk a well two hundred and twenty-five feet deep, and am thereby provided with an unfailing supply of the most delicious water. The water drawn from this well comes from what geologists call the greensand. Within sight of my balcony rise the well-known South Downs, which are hills of chalk covered with verdure. Now, if a bucket of water were taken from my well, and a similar bucket from a well in the South Downs, and if both buckets were handed over to a laundress, she would have no difficulty in telling you which she would prefer. With my well-water it would be easy to produce a beautiful lather. With the South Downs well-water it would be very difficult to do so. In common language, the one water is soft, like rain-water, while the other is hard. We have now to analyse and understand the mean- ing of ' hard water/ and to examine some of its effects. Suppose, then, three porcelain basins to be filled, the first with pure rain-water, the second with greensand- water, and the third with chalk- water ; all three waters at first being equally bright and transparent. Suppose the three basins placed on a warm hob, or even exposed to the open air, until the water of each basin has wholly evaparated. In evaporation the water only disappears ; the mineral matter remains. What, then, is the result ? ABOUT COMMON WATER. 335 In the rain-water basin you have nothing left behind ; in the greensand-water basin you have a small residue of solid mineral matter ; in the chalk-water basin you have a comparatively large residue. The reason of this is that chalk is soluble in rain-water, and dissolves in it, like sugar or salt, though to a far less extent ; while the water of my well, coming from the greensand, which is hardly soluble at all, is almost as soft as rain- water. The simple boiling of water is sufficient to precipi- tate a considerable portion of the mineral matter dis- solved in it. One familiar consequence of this is, that kettles and boilers in which hard water is used become rapidly incrusted within, while no such incrustation is formed by soft water. Hot-water pipes are sometimes choked by such incrustation ; and the boilers of steamers have been known to be so thickly coated as to prevent the access of heat to the water within them. Not only was their coal thus wasted, but it has been found necessary in some cases to burn the very spars in order to bring the steamers into port. There is no test of the presence of suspended matter in water or air so searching and powerful as a beam of light. An old English writer touched this point when he said : * The sun discovers atomes, though they be invisible by candle-light, and makes them dance in his beams.' In the purest water it may be filtered water; it may be artificially-distilled water ; it may be water obtained by the melting of the purest ice a Enfficiently strong searching beam reveals suspended matter. I have done my best to get rid of it, but can hardly say that I have completely succeeded. Differences in quantity are, however, very strikingly revealed. When, in a darkened study, I send a con- centrated beam through our well-water, after boiling, 836 ABOUT COMMON WATER. it appears turbid ; sent through the South Downs well- water, it appears muddy, so great is the quantity of chalk precipitated by the boiling. The mere exposure of hard water to the open air, where it can evaporate, softens it considerably, by the partial precipitation of the mineral matter which it held in solution. This last observation is important, because it en- ables us to explain many interesting and beautiful effects. In chalybeate springs, iron is dissolved in the water. Round about such springs, and along the rivu- lets which flow from them, red oxide of iron iron rust is precipitated by the partial evaporation of the water. In Iceland, the water of the Great Geyser holds a considerable quantity of flint or silica in solution. By a most curious process of evaporation this silica, as shown by Bunsen, has been so deposited as to enable what was at first a simple spring to build up, gradually, the wonderful tube of the Geyser, which is seventy- four feet deep and ten feet across, with a smooth basin, sixty feet wide, at the top. Again, the great majority of our grottos and caves are in limestone rock, which, in the course of ages, has been dissolved away by a stream. To the present hour are to be found, in most of these caves, the streams which made them. I have been through many of them, but through none which can compare in beauty with St. Michael's Cave in the Eock of Gibraltar. From the roof hang tapering stalactites, like pointed spears. From the floor rise columnar stalagmites. The stalac- tites gradually lengthen, while the stalagmites gradu- ally rise. In numerous cases stalactite and stalagmite meet, the sharp point of the former resting upon the broad top of the latter. Columns of singular beauty, reaching from floor to roof, are thus formed. Stalac- tites and stalagmites are to be seen in all phases of their ABOUT COMMON WATER. 837 approach towards each other; from the little spear, beginning like a small icicle in the roof, and the little mound of stalagmite on the floor, exactly underneath, up to the actual contact of both. The pillars and spears, the arches and corridors, the fantastic stone drapery, the fretted figures on the walls all contribute to pro- duce an effect of extraordinary magnificence. What is the cause of the wonderful architecture and decoration of St. Michael's Cave ? Probably some of my clever readers will have anticipated both this ques- tion and its answer. The rain, charged with its modi- cum of carbonic acid by the air, falls upon the limestone rock overhead, percolates through it, dissolves it, and, thus laden, reaches the roof of the cave. Here it is exposed to evaporation. The dissolved solid is, in part, deposited, and the base of the stalactite is planted against the roof. The charged water continues to drip, and the stalactite to lengthen. Escaping from the point of the stalactite, the drop falls upon the floor, where evaporation continues, and mineral matter is de- posited. The stalagmite rises ; the mound becomes a pillar, towards which the spear overhead accurately points, until, in course of time, they unite to form a column. A similar process goes on over the fretted walls. They shine with the water passing over them. Each water- film deposits its infinitesimal load, the quantity de- posited here and there depending on the inequalities of the surface, which cause the water to linger longer, and to deposit more at some places than at others. The substance most concerned in the production of all this beauty is called by chemists carbonate of lime. It is formed by the union of carbonic acid and lime. What lime is, of course, you already know ; its companion, carbonic acid, is, at ordinary temperatures, B3B ABOUT COMMON WATER. a very heavy gas. It effervesces in soda-water, and it constitutes a portion of the breath exhaled from the lungs. The weight of the gas, as compared with air, may be accurately determined by the chemist's balance. But its weight may also be shown in the following way. Let a wide glass shade be turned upside down, and filled with carbonic-acid gas. This is readily done, though when done you do not see the gas. Well, iron sinks in water, because 5t is heavier than water ; it swims on mercury, because it is lighter than mercury. For the same reason, if you blow a soap-bubble and dexterously shake it off, so that it shall fall into the glass shade, it is stopped at the top of the shade, bob- bing up and down, as if upon an invisible elastic cushion. The light air floats on the heavy gas. Almost any other acid, poured upon chalk or marble, liberates the carbonic acid. Its grasp of the lime is feeble, and easily overcome. When we dissolve and mix a common soda-powder, the tartaric acid turns the weaker carbonic acid out of doors. Many natural springs of carbonic acid have been discovered, one of which I should like to introduce to your notice. In the neighbourhood of the city of Naples there is a cave called the Grotto del Cane, a name given to it for a curious and culpable reason. During one of the eruptions of Vesuvius I paid a visit, in company with two friends, to Naples, and went to see, among the other sights of that wonderful region, the Grotto of the Dog. At a place adjacent we met a guide and some other visitors. At the heels of the guide was a timid little quadruped, which, for the time being, was the victim that gave the cave its name. We could walk into the cave without inconvenience, know- ing, at the same time, from the descriptions we had ABOUT COMMON WATER. 839 lieard and read, that our feet were plunged in a stream of heavy carbonic acid flowing along the bottom of the cave. The poor little dog, much against its will, was brought into the grotto. The stream of carbonic acid was not deep enough to cover the animal ; its master, accordingly, pressed its head under the suffocating gas. It struggled for a time, but soon became motionless apparently lifeless. Taken into the air outside, through a series of convulsions painful to look upon, it returned to life. The experiment is a barbarous one, and ought not to be tolerated. There are many ways of satisfying the curious, without cruelty to the dog. I made the following experiment, which seemed to surprise the by- standers. Placing a burning candle near the bottom of my hat, in the open air outside the cave, I borrowed a cap, and by means of it ladled up the heavy gas. Pouring it from the cap into the hat, the light was quenched as effectually as if water had been poured upon it. Made with glass jars instead of hats, this is a familiar laboratory experiment. We must now proceed slowly forward, making our footing sure as we advance. Lime is sparingly soluble in water, giving it a strong acrid taste. Lime-water is as clear as ordinary water ; the eye discerns no differ- ence between them. And now I want to point out to you one of the ways in which the carbonate of lime, which we have been speaking of, may be formed. I suppose you to have before you a tumbler, or beaker, filled with clear lime-water. By means of a pair of bellows, to the nozzle of which a glass tube is attached, you can cause pure air to bubble through the lime-water. It continues clear. You have been just informed that the breath exhaled from the lungs con- tains carbonic acid, and if this acid be brought into 840 ABOUT COMMON WATER. contact with lime, carbonate of lime will be formed. Knowing this, you can make the following experi- ment : Drawing your breath inward so as to fill your lungs, you breathe, by means of a glass tube, through the lime-water. Before you have emptied your lungs the clear lime-water will have become quite milky, the milki- ness being due to fine particles of carbonate of lime otherwise chalk formed by the union of the carbonic acid of your breath with the lime of the water. Take a well-corked champagne-bottle, from which the wine has been half removed, but which still re- tains, above the remaining wine, a quantity of carbonic- acid gas. It is easy to devise a means of causing this gas to bubble through lime-water. A heavy white pre- cipitate of chalk is immediately formed. We now come to a point of great practical impor- tance. The carbonate of lime exists in two forms: the simple carbonate, of which chalk is an example, which embraces a certain amount of carbonic acid ; and the bicarbonate, which contains twice as much. But the bicarbonate is far more soluble in water than the simple carbonate. Pure water dissolves only an ex- tremely small quantity of the simple carbonate of lime. But carbonic acid is sparingly diffused everywhere throughout our atmosphere, and rain-water always carries with it, from the air, an amount of carbonic acid, which converts the simple carbonate of the chalk into the bicarbonate, of which it can dissolve a con- siderable quantity. Every gallon of water, for example, taken from the chalk contains more than twenty grains of the dissolved mineral. By boiling, or by evaporation, this bicarbonate is re-converted into the insoluble carbonate, which renders our flasks of boiled chalk-water turbid, forms incrusta- tions in our kettles, and deposits itself as stalactites and ABOUT COMMON WATER. 841 stalagmites in our limestone caves. But there ia another way of converting the bicarbonate into the carbonate, which is well worthy of our attention. It will show how a man of science thinks before he ex- periments, and how, by experiment, he afterwards verifies his thought. Bearing in mind that the chalk- springs hold lime in solution as bicarbonate, it is plain that if we could rob this bicarbonate of half its car- bonic acid, we should reduce it to the simple carbonate, which is almost wholly insoluble. Think the matter over a little. What we have to combat is an excess of carbonic acid. Lime-water, with- out any carbonic acid, is easily prepared. Suppose, then, that we add to our chalk-water, with its double dose of carbonic acid, some pure lime-water; what would you expect? You would, at all events, think it probable that the bicarbonate of the chalk-water would give up its excess of carbonic acid to the lime, and assume the condition of the simple carbonate, which, because of its insolubility, would be precipitated as a white powder in the water. And, because chalk is heavier than water, you would conclude that the powder would sink to the bottom, leaving a clear, softened water overhead. Thus reasoned Dr. Clark, of Aberdeen, when he invented his beautiful process of softening water on a large scale. I have myself seen the process applied with success in various chalk-districts in England. Let us make a calculation. Every pound of chalk contains nine ounces of lime and seven ounces of car- bonic acid. Dissolved by rain-water, this simple carbonate becomes bicarbonate, where every nine ounces of lime combine with fourteen ounces of car- bonic acid. If, then, a quantity of pure lime-water containing nine ounces of lime be added to these 842 ABOUT COMMON WATER. twenty-three ounces of bicarbonate solution, the lime will seize upon seven ounces of the fourteen, and form two pounds of the nearly insoluble carbonate. In other words, nine ounces of lime can precipitate thirty-two ounces of chalk. Counting thus on a large scale, we find that a single ton of lime, dissolved in lime-water, suffices to precipitate three and a-half tons of the simple carbonate. Let me now describe to you what I saw at Canter- bury, where works for the softening of water were constructed by the late Mr. Homersham, civil engineer. I found there three reservoirs, each capable of contain- ing one hundred and twenty thousand gallons of water. There was also a fourth, smaller cistern, containing water aud lime in that state of fine division which is called ' cream of lime.' The mixture of water and lime is violently stirred up by currents of air driven through it. Brought thus into intimate contact with every particle, the water soon takes up all the lime it can dissolve. The mixture is then allowed to stand ; the solid lime falls to the bottom, and the pure lime-water collects overhead. The softening process begins by introducing a measured quantity of this lime-water into one of the larger cisterns. The hard water, pumped directly from the chalk, is then permitted to fill the cistern. When they come together, the two clear liquids form a kind of thin whitewash, which is permitted to remain quiet lor twelve or, still better, for twenty-four hours. The carbonate of lime sinks to the bottom of the reservoir, covering it as a fine white powder ; while above it is a water of extreme softness and transparency, and of the most delicate blue colour. This water harbours no organisms. Properly conducted to our homes, no in- fectious fever could ever be propagated by such water. ABOUT COMMON WATER. 843 Blue is the natural colour of both water and ice. On the glaciers of Switzerland are found deep shafts and lakes of beautifully blue water. The most striking example of the colour of water is probably that furnished by the Blue Grotto of Capri, in the Bay of Naples. Capri is one of the islands of the Bay. At the bottom of one of its sea-cliffs there is a small arch, barely sufficient to admit a boat in fine weather, and through this arch you pass into a spacious cavern, the walls and water of which shimmer forth a magical blue light. This light has caught its colour from the water through which it has passed. The entrance, as just stated, is very small ; so that the illumination of the cave is almost entirely due to light which has plunged to the bottom of the sea, and returned thence to the cave. Hence the exquisite azure. The white body of a diver who plunges into the water for the amusement of visitors is also strikingly affected by the coloured liquid through which he moves. Water yields so freely to the hand that you might suppose it to be- easily squeezed into a smaller space. That this is not the case was proved more than two hundred and sixty years ago by Lord Bacon. He filled a hollow globe of lead with the liquid, and, soldering up the aperture, tried to flatten the globe by the blows of a heavy hammer. He continued hammering ' till the water, impatient of further pressure, exuded through the solid lead like a fine dew.' Water was thus proved to offer an immense resistance to compression. Nearly fifty years afterwards, a similar experiment, with the same result, was made by the members of the Academy Del Cimento in Florence. They, however, used a globe of silver instead of a globe of lead. This experiment is everywhere known as * the Florentine experiment ' ; 844 ABOUT COMMON WATER. but Ellis and Spedding, the eminent biographers of Bacon, have clearly shown that it ought to be called * the Baconian experiment.' This stubbornness of water in the liquid condition has a parallel in its irresistible force when passing from the liquid into the solid state. Water expands in solidifying ; and ice floats on water in consequence of this expansion. The wreck of rocks upon the summits of some mountains is extraordinary. Scawfell Pike in England, and the Eggischhorn and Sparrenhorn in Switzerland, are cases in point. Under the guise of freezing water, a giant stone-breaker has been at work upon these heights. By his remorseless power, even the great and fatal pyramid of the Matterhorn is smashed and riven from top to bottom. I once lay in a tent for a night near a gully of the Matterhorn, and heard all night long the thunderous roar of the stone- avalanches which sweep incessantly down this mountain. On the slopes surrounding our Alpine home we find heaps and mounds, where slabs and blocks are piled together in apparent confusion. But we soon come to the sure and certain conclusion that these severed pieces are but parts of a once coherent rock, which has been shattered by the freezing of water in its fissures and its pores. When the ?evered masses are large, they are some- times left poised as ' rocking-stones.' A favourite excursion of ours in Switzerland takes us along a noble glacier, to the base of the great final pyramid of the Aletschhorn. There, a few years ago, was to be found a huge rock, with a horizontal upper surface so spacious that twenty of us have sometimes lunched upon it together. Literally as well as technically, it was a noble ' glacier-table.' That great boulder, of apparently iron strength, is now reduced to fragments by the ABOUT COMMON WATER. 845 universal pulveriser freezing water. I say pulveriser ; for, over and above its work of destruction upon the mountains, has it not disintegrated the bare rocks of the ancient earth, and thus produced the soils which constitute the bases of the whole vegetable world ? When water passes from the liquid to the solid condition, it is usually by a process of architecture so refined as to baffle our most powerful microscopes. I never observe without wonder this crystalline architecture. Look at it on the window-panes, or on the flags over which you walk on a frosty morning. Nothing can exceed the beauty of the branching forms that overspread the chilled surfaces. Look at the feathery plumes that sometimes sprout from wood, or cloth, or porous stones. The reflecting mind cannot help receiving from this definite grouping and ordering of the ultimate particles of matter suggestions of the most profound significance. Many months ago I read a stanza from your de- lightful poet, Bryant, wherein he refers to the * stars ' of snow. Those stellar forms of falling snow repeat themselves incessantly. I have seen the Alps in mid- winter laden with these fallen stars ; and three or four days ago, they showered their beauty down upon me in England. Dr. Scoresby observed them in the Arctic regions, and Mr. Glashier has made drawings of them nearer home. The ice-crystal is hexagonal in form, and the snow- stars invariably shoot forth six rays. The hexagonal architecture is carried on in the formation of common ice. Some years ago I set a large lens in the sun, and brought the solar rays to a focus in the air. I then placed a slab of pure ice across the convergent beam. 846 ABOUT COMMON WATER. Sparks of light, apparently generated by the beam, immediately appeared along its track. Examining the ice afterwards with a magnifying- lens, I found that every one of those brilliant points constituted the centre, or nucleus, of a beautiful liquid flower of six petals. There was no deviation from this number, because it was inexorably bound up with the crystalline form of the ice. Thus, in a region withdrawn from the inattentive eye, we find ourselves surprised and fascinated by the methods of Nature. 1890. PERSONAL RECOLLECTIONS OF THOMAS IT is an age of ' Reminiscences ' ; known to me, in great part, through extracts and reviews. Pleasant reading, in their fulness, many of these records must surely be. Carlyle has given us his * Reminiscences ' written, alas I when he was but the hull of the true Carlyle. Still, methinks the indignation thereby aroused was out of proportion to the offence. It is not, how- ever, my task or duty to defend the * Reminiscences.' In clearer and happier moments, Carlyle himself would have recoiled from publishing their few offending pages. When they were written, all things were seen by him through the medium of personal suffering, physical and mental. This lurid atmosphere defaced, blurred, and sometimes inverted like mirage, his coast-line of memory. The figure of himself, standing on that quivering and delusive shore, has suffered more from the false refraction than anything else. With the piercing insight which belonged to him all this, in healthier hours, would have been seen, weighed, and rectified by Carlyle himself. Vast is the literature which has grown around the memory of this man. It is not my desire, or intention, to sensibly augment its volume. I wish merely to con- tribute a few memorial notes which I am unwilling to let die, but which, in presence of what has gone before, are but as a pebble dropped upon the summit of a tor. 1 Written for the most part from memory in the Alps, 1889, and published in the Fortnightly Review. January. 1890. 23 348 PERSONAL RECOLLECTIONS OF There are amongst us eminent men who knew Cartyle longer, and who saw him oftener, than I did whose store of memories is therefore fax larger than mine. But it was my fortune, during some of the most im- pressive phases of his life, to be very close to him ; and though my visits to his home in Chelsea, and our com- mon rambles in London and elsewhere, were, to my present keen regret^ far fewer than either of us wished them to be, they gave me some knowledge of his inner life and character. Better however than in any formal record, that life is to be sought and found in his imperishable works. There we best see the storm of his passion, the depth of his pity, the vastness of his knowledge his humour, his tenderness, his wisdom, his strength. As long as men continue capable of appreciating what is highest in literary achievement, these works must hold their own. When, before a group of distinguished and stead- fast friends, the statue of Carlyle was unveiled on t he Thames Embankment, I briefly referred to my first acquaintance with his works. 'Past and Present,' the astonishing product of seven weeks' fierce labour in the early part of the year, was published in 1843; and soon after its publication I met some extracts from the work in the Preston newspapers. I chanced, indeed, to be an eve-witness of the misery which at that time so profoundly moved Carlyle. With their hands in their pockets, with nothing in their stomachs, but with silent despair fermenting in their hearts, the 'hunger-stricken, pallid, yellow-coloured' weavers of Preston and the neighbourhood stalked moodily through the streets. Their discontent rose at length to riot, and some of them were shot down. Such were the circumstances under which Carlyle appealed to Exeter THOMAS CARLYLE. 849 ITall, with its schemes of beneficence for aborigines tar away, 'These yellow- coloured for the present absorb all my sympathies. If I had a twenty millions with model farms and Niger expeditions, it is to them I would give it.' Under the same circumstances he warned his * Corn-lawing friends ' that they were driving into the frenzy of Socialism 'every thinking man in England.' . With my memory of the Preston riots still vivid, I procured ' Past and Present,' and read it per- severingly. It was far from easy reading ; but I found in it strokes of descriptive power unequalled in my experience, and thrills of electric splendour which carried me enthusiastically on. I found in it, more- over, in political matters, a morality so righteous, a radicalism so high, reasonable, and humane, as to make it clear to me that without truckling to the ape and tiger of the mob, a man might hold the views of a radical. The first perusal of the work gave me but broken gleams of its scope and aim. I therefore read it a second time, and a third. At each successive reading my grasp of the writer's views became stronger and my vision clearer. But even three readings did not satisfy me. After the last of them, I collected econo- mically some old sheets of foolscap, and wrote out thereupon an analytical summary of every chapter. When the work was finished I tied the loose sheets together with a bit of twine and stowed them away. For many years they remained hidden from me. I had passed through the railway madness of the ' forties,' emerging sane from the delirium. I bad studied in Germany, had lectured at the Rojal Institution, and in 1853 had been appointed its Professor of Natural Philosophy. For fifteen years I had enjoyed the friendship of Faraday, whose noble and illustrious life 350 PERSONAL RECOLLECTIONS 0? came to an end in 1867, on Hampton Court Green. Keverently, but reluctantly, I took his place as Super- intendent of the Royal Institution, vastly preferring, if it could have been so arranged, to leave Mrs. Fara- day in undisturbed possession of the rooms which had been her happy home for six-and-forty years. The thing, however, could not be. On returning from one of my Alpine expeditions I found at the entrance of the place which had been occupied successively by Davy and Faraday, my name upon the wall. It was to me more of a shock than a satisfaction. The change, however, brought me nearer to Carlyle; and to Albemarle Street from time to time he wended his way to see me. Once he found me occupied, not with a problem of physics, but with a question of biology of fundamental import. The origin of life was, is, and ever will be, a question of profoundest interest to thoughtful men. In the early * seventies ' I was busy experimenting on this question, my desire being to bring to bear upon it physical methods which should make known the unmistakable verdict of science re- garding it, and thus abolish the doubt and confusion then existing. Permitting air to purify itself by the subsidence of all floating motes, so that the track through it of a sunbeam, even when powerfully concen- trated, was invisible, infusions of meat, fish, fowl, and vegetables were exposed to such air and found inca- pable of putrefaction. The vital oxygen was still there; but with the floating motes, the seminal matter of the atmosphere had vanished, and with it the power of generating putrefactive organisms. The organisms, in other words, required the antecedent seed there waft no spontaneous generation. By means of gas stoves rooms had been raised to the proper temperature, and into one of these rooms, which was stocked with my THOMAS CARLYLE. 851 noteless chambers, I took Mr. Carlyle. He listened with profound attention to the explanation of the ex- periments. They were quite new to him ; for microbes^ bacilli, and bacteria were not then the household words which they are now. I could notice amazement in his eyes as we passed from putrefaction to antiseptic surgery, and from it to the germ theory of communi- cable disease. To Carlyle life was wholly mystical - incapable of explanation and the conclusion to which the experiments pointed, that life was derived from antecedent life, and was not generated from dead matter, fell in with his notions of the fitness of things. Instead, therefore, of repelling him, the experiments gave him pleasure. After quitting the laboratory I took my guest up- stairs, and placed him in an armchair in front of a cheerful fire. The weather was cold, and I therefore prepared for him a tumbler of mulled claret. And now we arrive at the cause which induces me to speak thus early of a late event. About a fortnight prior to this visit, while rummaging through a mass of ancient papers, I had come upon the long-lost sheets of foolscap which contained my analysis and summary of the various chapters of ' Past and Present.' The packet, tied with twine as aforesaid, and bearing the yellow tints of age, lay in an adjacent drawer. At length I said to him, ' Now you shall see something that will interest and amuse you.' I took the ragged sheets from the drawer, told him what they were and how they had originated, and read aloud some of the passages which had kindled me when young. He listened, sometimes clinching a paragraph by a supplement or ratification, but fre- quently breaking forth into loud and mellow laughter at his own audacity. It would require gifts greater even than those of Boswell to reproduce Carlyle. I 352 PERSONAL RECOLLECTIONS OF think it was my sagacious friend, Lady Stanley of AlJer- ley, who once remarked to me that in the reported utterances of Carlyle we miss the deep peal which rounded off and frequently gave significance to all that had gone before. 1 Our fun over the eviscerated ' Past and Present ' continued for some time, after which it ceased, and an expression of solemn earnestness over- spread the features of the old man. * Well,' he said at length, in a voice touched with emotion, ' what greater reward could I have than to find an ardent young soul, unknown to me, and to whom I was personally un- known, thus influenced by my words.' We continued our chat in a spirit of deeper earnestness, and after he had exhausted his goblet we walked together down Albemarle Street to Piccadilly, his tough old arm encircling mine. There I saw him safely seated in a Krompton omnibus, which was his usual mode of loco- motion. When he was inside every conductor knew that he carried a great man. All this was late in the day of my acquaintance with Carlyle. I first saw him, and heard his voice, in the picture gallery of Bath House, Piccadilly. I noticed the Scottish accent, not harsh or crabbed as it sometimes. is, but rich and pleasant, which clung to him throughout his life, as it did also to Mrs. Somerville. I first became really acquainted with him at the ' Grange, the Hampshire residence of the accomplished and high-minded Lord Ashburton. Sitting beside him at luncheon, I spoke to him, and he answered me bluntly. James Spedding was present, and to render myself sure of his identity I asked Carlyle, in a low voice, whether the gentleman opposite was not Speddiug ? Yes,' he 1 From Dr. Garnet's excellent Life of Carlyle I lean? that Mr Allingham had also drawn attention to this point. THOMAS CAELYLE. 853 replied aloud, 'that's Spedding.' He had no notion of tolerating a confidential whisper. The subject of homoeopathy was introduced. Carlyle's appreciation of the relation of cause and effect was as sharp and clear as that of any physicist ; and he thought homoeopathy an outrageous defiance of the proportion which must subsist between them. I sought to offer an explanation of the alleged effects of * infinitesimals,' by reference to the asserted power of the Alpine muleteer's bell to bring down an avalanche. If the snow could be loosened by a force so small, it was because it was already upon the verge of slipping. And if homoeopathic globules had any sensible effect, it must be because the patient was on the brink of a change which they merely precipi- tated. Carlyle, however, would listen to neither defence nor explanation. He deemed homoeopathy a delusion, and those who practised it professionally impostors. He raised his voice so as to drown remonstrance ; while a ' tsh ! ' with which Mrs. Carlyle sometimes sought to quiet him, was here interposed. Casting homoeo- pathy overboard, he spoke appreciatively of George III. The capacity of the King was small, but he paid out conscientiously the modicum of knowledge he possessed. This was illustrated by the way in which he collected his library, always seeking the best advice and pur- chasing the best books. Carlyle's respect for conscien- tiousness and earnestness extended to all things. We once went together to an exhibition of portraits at South Kensington. Pausing before the portrait of Queen Mary (Bloody Mary, as we had been taught to call her), he musingly said, * A well-abused woman, l it by no means a bad woman rather, I should say, a good woman acting according to her lights.' He ought, perhaps, to have extended the same tolerance to Ignatius Loyola, whom he abhorred and scathed. In the 354 PEKSONAL RECOLLECTIONS OF evening, while we stood before the drawing-room fire, 1 spoke to him of Emerson. There was something lofty in the tone of Carlyle's own voice as be spoke of the ' loftiness ' of his great American friend. 1 I mentioned Lewes's life of Goethe, which I had been just reading, and ventured to express a doubt whether Lewes, as a man, was strong enough to grapple with his subject. He was disposed to commend the Life as the best we had, but he was far from regarding it as adequate. Oarlyle was a bold rider, and during this visit to the Grange he indulged in some wild galloping. Professor Hofmann was his companion, and he humorously de- scribed their motion as tantamount to being shot like a projectile through space. Brookfield was one of the guests, a clergyman of grace and culture, who might have been a great actor, and who entertained a high notion of the actor's vocation. One evening he gave us an illustration of his dramatic gifts extemporising, and drawing by oblique references, the principal person- ages round him into his performance. It was then I first heard the resonant laugh ot Carlyle. Himself a humourist on a high plane, he keenly enjoyed humour in others. Lady Ashburton, with fine voice and ex- pression, read for us one of Browning's poems. It was obvious from his ejaculatory remarks that Carlyle enjoyed and admired Browning. As time went on I drew more closely to Carlyle, 1 Their friendship continued unimpaired to the end. Not long before Carlyle's death, I noticed two volumes of the same shape and binding on the table of his sitting-room. Opening one of them, I found written on the fly-leaf : 1 To Thomas Carlyle 'with unchangeable affection ' from Ralph Waldo Emerson.' The two volumes were Emerson's own collected works. ' That,' I said, 'is as it ought to be: you and Emerson must, remain friends to th- last.' 'Aye.' he responded, 'you are quite right; take th relume.* with you, but return them punctually'; which J did. THOMAS CAELYLE. 353 seeking, among other things, to remove all prejudice by making clear to him the spirit in which the highest scientific minds pursued their work. They could not detach themselves from their fellow-men, but history showed that they thought less of worldly profit and applause, and practised more of self-denial than any other class of intellectual workers. Carlyle had been to the Boyal Society, but found the meetings he at- tended flat, stale, and unprofitable. Not knowing how the communications were related to the general body of research, they, of course, lacked the sap which their roots might have supplied to them. He was surprised to fmd me fairly well acquainted with ' Wilhelm Meister's Wanderjahre,' declaring that, as far as his knowledge went, the persons were few and far between who showed the least acquaintance with Goethe's 'Three Keve- rences* reverence for what is above us, reverence for what is around us, reverence for what is beneath us. To this feature of Goethe's ethics Carlyle always at- tached great importance. Among the spoken and written words of our age the utterances of Goethe were, in his estimation, the highest and weightiest. Of Fichte and Schiller he sometimes spoke with qualified admiration of Goethe never. He may have been indebted to the great German for a portion of his spiritual freedom, and such indebtedness men do not readily forget. Unswerving in his loyalty, Carlyle, towards the end of his life, would have ratified by re-subscription the ardent outburst of 1831. 'And knowest thou no prophet, even in the vesture, environ- ment, and dialect of this age ? None to whom the Godlike has revealed itself, and by him been again prophetically revealed ; in whose inspired melody, even in these rag-gathering and rag-burning days, Man's life a^-ain begins, were it but afar off, to be divine? O O ' 356 PERSONAL RECOLLECTIONS OP Knowest thou none such ? I know him and name him Goethe.' ' The majesty of Goethe's character seemed, in Carlyle's estimate of him, to dissolve all his eiTors, both of intellect and conduct. The standards of the homilettc market-place were scornfully brushed aside ; drawbacks and qualifications were blown away like chaff, 'the golden grain' of the mighty German husbandman being alone garnered and preserved. I had various talks with him about Goethe's mis- taken appreciation of the ' Farbenlehre ' as the greatest of his works. To Carlyle this was a most pathetic fact. The poet thought he had reached the adamant of natural truth, and alas ! he was mistaken. But, after all, was he mistaken ? Over German artists the * Far- benlehre' had exercised a dominant influence. Could it be all moonshine ? Thus he mused. While holding firmly to the verdict that with regard to theory Goethe was hopelessly wrong, I dwelt with pleasure on the wealth of facts which his skill and industry had accumulated. This to a certain extent gratified Car- lyle, but he sighed for the supplement necessary to the scientific completeness of his hero. He was intimately acquainted with every nook and corner of Goethe's work sometimes more intimately than the poet's own countrymen. I once had occasion to quote the poem ' Mason Lodge,' translated and published in 4 Past and Present.' 8 The article in which it was quoted was 1 Sartor Resartus, Library Edition, p. 244. * Book III. chap. xv. A very noble song, and a great favourite of Carlyle's. With it he wound up his Rectorial address at Edin- burgh. The reciting of two of its verses, under peculiar circum- lances, had an important influence on my own destiny. ' Solemn before us, Veiled, the dark Portal, Goal of all mortal: Htars silent o'er us, Graves under us silent 1 Here eyes do regard you, In Eternity's stillness; Here is all fulness, Ye brave, to reward yon. Work and despair not.* THOMAS CAELYLE. 357 afterwards translated into German ; the original poem, therefore, required hunting up. None of my friends in Berlin knew anything about, it. On learning this I went down to Chelsea, where, in answer to my inquiry, Carlyle promptly crossed his sitting-room and took from a shelf the required volume. Thus, through the years, I kept myself in touch with this teacher and in^pirer of my youth. The ' Life of Frederick' drew heavily upon his health and patience. His labours were intensified by his conscientiousness. He proved all things, with the view and aim of holding fast that which was historically good. Never to err would have been superhuman ; but if he erred, it was not through indolence or lack of care. The facts of history were as sacred in his eyes as the ' constants' of gravitation in the eyes of Newton ; hence the severity of his work. The ' Life of Frederick,' moreover, worried him ; it was not a labour into which he could throw his whole soul. He was continually pulled up by sayings and doings on the part of his hero which took all en- thusiasm out of him. * Frederick was the greatest administrator this world has seen, but I could never really love the man.' Such were his words. While engaged on this formidable task, he was invited to stand for the Rectorship of Edinburgh University. For the moment he declined, promising, however, to consider the proposal when his labours on Frederick were ended. The time came, and he accepted the in- vitation. Disraeli was pitted against him, but he won the election by an overwhelming majority. His trans- port to Edinburgh had then to be considered. After many talks with him and his wife, the simplest and safest solution of the difficulty seemed to be that I should take charge of him myself. 353 PERSONAL RECOLLECTIONS OP It was arranged that he should go first to Frey- Btone, in Yorkshire, and pay a short visit to Lord Houghton. On the morning of March 29, 1866, I drove to Cheyne Row, and found him punctually ready at the appointed hour. Order was Carlyle's first law, and punctuality was one of the chief factors of order. He was therefore punctual. On a table in a small back parlour below-stairs stood a 'siphon,' protected by wickerwork. Carlyle was conservative in habit, and in his old age he held on to the brown brandy which was in vogue in his younger days. Into a tumbler Mrs. Carlyle poured a moderate quantity of this brandy, and filled it up with the foaming water from the siphon. He drank it off, and they kissed each other for the last time. At the door she suddenly said to me, * For God's sake send me one line by telegraph when all is over.' This said, and the promise given, we drove away. In due time we reached Freystone, where the warmest of welcomes greeted Carlyle. A beautiful feature in the record of Carlyle's relations to his friends is the loving loyalty of Lord Houghton. Not long prior to his lamented death he sent me an extract from a letter written by Carlyle to his wife on the occasion, I believe, of his first visit to Freystone. It had been purchased by Lord Houghton from some collector of letters, into whose hands it had fallen. It showed how long-standing Carlyle's malady of sleeplessness had been. It spoke of the weary unrest of the previous night the ceaseless tossing to and fro and of the comfort he experienced in thinking of her, as he smoked his morning cigar in the sunshine. On the first night of his last visit to Freystone, the unrest waa not only renewed but intensified. Railways had multi- plied ; they clasped Freystone as in a ring, and their THOMAS CAELYLE. 359 whistles were energetically active all night. I feared the result, and my fears proved only too well grounded. In the morning I found Carlyle in his bedroom, wild with his sufferings. He had not slept a wink. It ought to be noted that the day previous he had dined two or three hours later than was his wont, and had engaged in a vigorous discussion after dinner. Look- ing at me despairingly, he said, ' I can stay no longer at Freystone, another such night would kill me.' * You shall do exactly as you please,' was my reply. ' I will explain matters to Lord Houghton, and he, I am persuaded, will comply with all your wishes.' I spoke to Lord Houghton, who, though sorely disappointed, agreed that it was best to allow his guest complete freedom of action. It was accordingly arranged that we should push on to Edinburgh. Carlyle's breakfast was prepared. He partially filled a bowl with strong tea, added milk, and an egg beaten up. Eendered thus nutritive, the tea eeemed to soothe and strengthen him. As he breakfasted our projects were discussed. Once, after a pause, he exclaimed, ' How ungrateful it is on my part, after so much kindness, to quit Frey- gtone in this fashion.' Taking prompt advantage of this moment of relenting, I said, * Do not quit it, but stay. We will take a pair of horses and gallop over the country for five or six hours. When you return you shall have a dinner like what you are accus- tomed to at home, and I will take care that there shall be no discussions afterwards.' He laughed, which was a good sign. I stood to my guns, and he at length yielded Lord Houghton joyfully ratified the programme, and two horses were immediately got ready. The animal bestrode by Carlyle was a large bony grey, with a terribly hard mouth. He seemed dis- 360 PERSONAL RECOLLECTIONS OF posed to bolt, and obviously required a strong wrist to rein him in. Carlyle was no longer young : paralysis agitans had enfeebled his right hand for some time my anxiety was great. But after sundry imprecations and strenuous backward pulls, the horse was at length clearly mastered by its rider, and we fleetly sped along. Through lanes, over fields, along high-roads, past turnpike gates where I paid the toll. This con- tinued for at least five hours, at the end of which we returned, and handed the bespattered horses over to the groom. The roads and lanes had been abominable, mud to the fetlocks, not to speak of the slimy fields. Had the groom's feelings been allowed open vent, we should have had imprecations on his part also. We beard only a surface murmur, but the storm, I doubt not, dis- charged itself behind our backs in the stable. Carlyle went to his room, donned his slippers and his re-< spectable grey dressing-gown. Carrying with him one of the long 'churchwardens' which he always obtained from Glasgow, he stuffed it full of tobacco Choosing a position on the carpet by the hall fire which enabled him to send the products of combustion up the chimney, to the obvious astonishment of the passing servants he began to smoke. Having with me at the time a flask of choice pale brandy, of this, mixed with soda-water, I gave him a stiff tumbler. The ride had healthily tired him, and he looked the picture of content. At six o'clock his simple dinner was set before him, and he was warned against discussion. It was the traditional warning of the war-horse to be quiet when he hears the bugle sound. In the evening discussion began with one of the guests, and I could eee that Carlyle was ready to dash into it as im- petuously as he had done the night before. I laid my hand upon his arm and said sternly, ' We must ha\a THOMAS CARLYLE. 36! no more of this.' He arched his brows good-humouredly, burst into laughter, and ended the discussion. I ac- companied him to his bedroom, every chink and fissure of which had been closed to stop out both light and sound. * I have no hope of sleep,' he said, * and I will come to your room at seven in the morning.' My reply was, 'I think you will sleep, and if so, I will come to your room instead of your coming to mine.' My hopes were mainly founded on the vigorous exercise he had taken ; but the next day being Good Friday, I also hoped for a mitigation of the whistle nuisance. At seven o'clock, accordingly, I stood at his door. There was no sound. Eeturning at eight, I found the same dead silence. At nine, hearing a rustle, I opened his door and found him dressing. The change from the previous morning was astonishing. Never before or afterwards did I see Carlyle's countenance glow with such happiness. It was seraphic. I have often thought of it since. How in the case of a man possessing a range of life wide enough to embrace the demoniac and the godlike, a few hours' sound sleep can lift him from the grovelling hell of the one into the serene heaven of the other 1 This question of sleep or sleeplessnese hides many a tragedy. He looked at me with boundless blessedness in his eyes and voice. ' My dear friend, I am a totally new man ; I have slept nine hours with- out once awaking.' That night's rest proved the pre- lude and guarantee of his subsequent triumph at Edin- burgh. We had been joined at Freystone by Huxley, 1 and in due time started, all three together, for the beautiful 1 And by the aole and lamented Mr. Maclennan. Dr. Hirst also paid a brief visit to Freystone, and was afterwards one of Carlyle'i hearers in Edinburgh. 362 PERSONAL RECOLLECTIONS OP metropolis of the North. There Carlyle was lodged in the house of his gentle and devoted friend, Erskine of Linlathen. He was placed as far from the noises of the street, in other words as near the roof, as possible. I saw him occasionally in his skyey dormitory, where, though his sleep did not reach the perfection once attained at Frey stone, it was never wholly bad. There was considerable excitement in Edinburgh at the time copious talking and hospitable feasting. The evening before the eventful day I dined at Kinellan with my well-beloved friends, Sir James and Lady Coxe, whose permanent guest I was at the time. Sir David and Lady Brewster were there, and Russell of the Scots- man. The good Sir David looked forward with fear and trembling to what he was persuaded must prove a fiasco. ' Why,' he said to me, ' Carlyle has not written a word of his Address ; and no Rector of this University ever appeared before his audience without this needful preparation.' In regard to the writing I did not share Sir David's fear, being well aware of Carlyle's marvellous powers of utterance when he had fair play. There, however, was the rub. Would he have fair play? Would he come to his task fresh and strong, or with the pliancy of his brain destroyed by sleeplessness? This surely is the tragic side of insomnia, and of the dyspepsia which frequently generates it. 'It takes all heart out of me, so that I cannot speak to my people as I ought.' Such were the words of a worthy Welsh clergyman whom I met in 1854 among his native hills, and whose unrest at night was similar to that of Carlyle. Time would soon deliver its verdict. The eventful day came, and we assembled in the ante- room of the hall in which the address was to be delivered Carlyle in his rector's robe, Huxley, Ramsay, Erskirie, and myself in more sober gowns. We were all four to- THOMAS CARLYLE. 363 he doctored. The great man of the occasion had declined the honour, pleading humorously that in heaven there might be some confusion between him and his brother John, if they both bore the title of doctor. I went up to Carlyle, and earnestly scanning his face, asked: 'How do you feel?' He returned my gaze, curved his lip, shook his head, and answered not a word. ' Now, ' I said, * you have to practise what you have been preaching all your life, and prove yourself a hero.' He again shook his head, but said nothing. A proces- sion was formed, and we moved, amid the plaudits of the students, towards the platform. Carlyle took his place in the rector's chair, and the ceremony of con- ferring degrees began. Looking at the sea of faces below me young, eager, expectant, waiting to be lifted up by the words of the prophet they had chosen I forgot all about the degrees. Suddenly I found an elbow among my ribs * Tyndall, they are calling for you.' I promptly stood at * 'tention ' and underwent the process of baptism. The degrees conferred, a fine tall young fellow rose and proclaimed with ringing voice from the platform the honour that had been con- fered on 'the foremost of living Scotchmen.' The cheers were loud and long. Carlyle stood up, threw off his robe, like an ancient David declining the unproved armour of Saul, and in his carefully-brushed brown morning-coat came forward to the table. With nervous fingers he grasped the leaf, and stooping over it looked earnestly down upon the audience. ' They tell me,' he said, ' that I ought to have written this address, and out of deference to the counsel I tried to do so, once, twice, thrice. But what I wrote was only fit for the fire, and to the fire it was compendiously committed. You must therefore listen to and accept what I say to you as coming straight 24 3f>4 PERSONAL RECOLLECTIONS OF from the heart.' He began, and the world already knows what he said. I attended more to the aspect ot the audience than to the speech of the orator, which contained nothing new to me. I could, however, mark its influence on the palpitating crowd below. They were stirred as if by subterranean fire. For an hour and a half he held them spellbound, and when he ended the emotion previously pent up burst forth in a roar of acclamation. With a joyful heart and clear conscience I could redeem my promise to Mrs. Carlyle. From the nearest telegraph-office I sent her a despatch of three words: 'A perfect triumph,' and returned towards the hall. Noticing a commotion in the street, I came up with the crowd. It was no street brawl ; it was not the settlement of a quarrel, but a consensus of acclamation, cheers and * bravos,' and a general shying of caps into the air ! Looking ahead I saw two venerable old men walking slowly arm-in-arm in advance of the crowd. They were Carlyle and Erskine. The rector's audience had turned out to do honour to their hero. Nothing in the whole ceremony affected Carlyle so deeply as this display of fervour in the open air. All this was communicated by letter to Mrs. Carlyle; and as I shared the general warmth of the time, it is to be assumed that my letters were of the proper temperature. She, at all events, wrote warmly enough about me afterwards. Wound up, as she had been, to ouch an intense pitch of anxiety, the thin-spun life was almost l slit ' by the telegram. Her joy was hysterical. But after a little time, aided by the loving cure of friends, she shook away all that was abnormal in her happiness. She dined that evening with John Forster. Dickens and Wilkie Collins were of the party. She entered the drawing-room exultant, waving the telegram in the air. Warm felicitations were not wanting, and THOMAS CARLYI
