THE FINDING OF TRUE FACTS. AN INAUGUEAL ADDEESS. IT is not given to man, in following out any branch of natural science, to draw the line of theoretical completeness, and to say to the searcher after truth : te Hitherto shalt thou come, but no farther." It is, on the other hand, one of the happiest results of true science, that it raises the perpetual wish for fresh inquiry. The completest theories are most easily shaped when there is the least knowledge. Philosophical systems are not difficult to build up, when you have only a few facts to account for, and are not in much fear of others being thrust in your way which may not harmonize with your sys- tem. In old times, there were "Philosophers" enough, in this sense ; and there was no lack of systems and schools, each of which had followers who denounced the rudeness of every daring intruder, and found that by far the most convenient method to answer the questioner was by the curled lip and self-sufficient sneer. Modern times, and even our own days, abound in such philosophers, quite as much as the days when the Porch and the Grove were frequented at Athens. But the happy difference is this : that these philoso- phers cannot now get the exclusive hearing ; but, however wedded individuals may be to any darling theory, and however jealous a self-constituted coterie may be of intruders upon ground which they would fain hold appropriated as their own domain, the door is now open to all, to seek truth arid pursue it, and to question Nature and grapple with her secrets: and theories, however cherished, and jealousies, however narrow, must, in the end, fall before the accu- mulated light brought to bear by persevering searchers. 058 A 2 4 It is not the most laborious and successful searcher who is the most disposed to theorize, or the readiest to quarrel with the fruits won by a fellow labourer. On the contrary, it is your men of small grasp and little range that are ever the quickest to shape a theory, and the most positive to maintain it. The firmer the grasp of the real facts of nature, and the wider the range of inquiry into these, the more cautious becomes the daring of the generalizer ; and the more strongly does he feel the importance of two things : first, that as many facts as possible shall be collected, by which every generalization shall be tried ; and second, that every fact got shall be a true fact. The latter is a point often not enough considered, and which I shall more fully touch on presently, content with now reminding you that it has been said, with great justness, that there are even more ia\$>Q facts than there are false theories in the world. Geology is a science that rests exclusively on a knowledge of the outer world, and can only consist, as a science, in the true interpre- tation of the facts which that world shows to us. There is no science to which what I have said as to theories can more thoroughly apply ; and there is no science which has been, and is liable to be, more hindered by false facts. There is none, therefore, in which the gathering up of true facts, and the bringing these together as a common stock for the use of science, can be more needed. A well* known geologist, writing to me, a few days ago, says : " I believe we want workers, not theorizers ; men who will bide their time, and not propounders of pretty theories, for self and immediate glorifica- tion. Much remains to be done in careful work, and well directed energy." The man whose life is passed on some outlying corner of the lias or the coal-formations, and who sees only the special class of facts that surround him, may be very apt to indulge himself in shaping theories. Enlarge his scope, make his gatherings part of an accumulated store taken from a much wider field ; and you check, at once, the disposition to theorize, and teach him that the first truth, and the most necessary of all to be learned, but perhaps the most difficult, is, that no fact can be known to be a true fact till its relations have been studied ; for that there is no one fact in all physical nature, any more than in man's moral and social nature, which can stand by itself, naked and alone, but that the qualities of every fact, and therefore whether this or that statement of it is a true or a false fact, depend entirely upon the relations in which it stands to other things. What I have said is enough for me now to take as ground for the work set to itself by the Association whose opening meeting we hold this evening. Instead of any apology being needed for the forming of such an Association, or of those who have taken part in its formation having reason to give any other heed than a pass- ing smile to the jealousies which, unworthily to themselves, some men have indulged in at the boldness of this attempt, it is matter of surprise that it has been so long delayed. Geology is a study which cannot be followed merely in the laboratory or the closet ; nor can the growth and development with which it deals, be watched among groups collected by the traveller, and brought together in the garden or the menagerie. It can be learnt only in the field. The very power to judge rightly of its facts, and to. marshal them in available order, must be got in the field. Not, of course, that every man must himself have travelled over every " Formation," before he can understand Geology. But, in order to bring home to the mind the bearings of observations made upon many large groups of the facts that lie within this class, the student must have accus- tomed himself to a personal knowledge of the appearances and shapes under which rocks and stratifications are actually found beneath the mere outer covering of the earth. Now it is, with the active mind, a great increase to the mere pleasure of travel, or even of rural wan- derings, to have an object of interest added to the charm which the landscape gives to the eye. Hence, Geology, so soon as it became known as a science, invoked at once, in every corner, the active curiosity and interest of numbers of those who are accustomed to walk abroad with the open eye. Each of these finds that he can gather something which helps to illustrate, if not to add to, that- stock of facts, on the true interpretation of which, by careful com- parison, the truthfulness of the science must depend. But even this, though alone enough to make such an Association as the pre- sent the natural and almost necessary growth of the pursuit of such a science, is by no means the most important reason for its active existence, nor will be the widest sphere of its usefulness. It is within a very few years, comparatively speaking, that the enterprise of this country has become so extraordinarily developed in the way of those Public Works which deal with the very conformation and substance of the earth's surface. Canals, railways, docks, works of drainage, and other town improvements, are things which make Geology one of the most important and practical of all the sciences that mark our time. To stop now to point out wherein the science of Geology is necessary in every one of these classes of works, is quite unnecessary. Every one knows that the kind and the dip of the Strata are things on which every work of the sort depends, and in the management and adaptation of which the skill of the engineer is shown. We have not, now, the smallest public work done in a little country town, hardly a building of any pretensions put up, but the Surveyor's or Engineer's report professes, at the least, to give one section to the " Geological features." I am sorry to be obliged to say that, while we have thus abundant proof of a knowledge of the importance of this science, such Reports very often contain lamentable proof that the knowledge has halted here. An Associa- tion which gives the means of interchanging experience, and of bringing together facts, and comparing these, cannot, therefore, but be of very great public service ; while the opportunities which those engaged on works of these sorts have, of observing facts and collect- ing illustrations, will be far more likely to be made good use of by them when an Association like the present opens its doors to them, than when facts and observations, however carefully made, have little chance of ever doing other than remain buried in the note- book. An impulse may hence be expected to be given to Geological science, that will be of first-rate importance, as well to the verification of conclusions already drawn, as to the settling of problems that are admitted to stand open, and, even further, to the opening of fields which have been as yet little worked in some cases perhaps hardly suspected to exist. " What we want/' says Mr. Salter, in a late number of an able publication devoted to this science, " what we want, in the present state of Geology, is abundance of good facts ; and these can only be collected by the industry of local observers, who will communicate these results in a tangible form, available for the workers on particular subjects. . . . There is no pleasure," he adds, " so great as in working for a definite object, with the cer- tainty that your results, however small, will aid in attaining it. Many a holiday may be most profitably occupied (which would otherwise be lost) by confining the attention to one bed, or a set of beds, instead of hammering away under a vague impression that something is to be done, though you know not exactly what."* We hope that, at every meeting of this Association, communications of observed facts will be made by members. The statement of these will appear in the printed minutes of our proceedings ; and these, being circulated among all our members, will convey to every quarter some of those means for comparison, and suggestions for research, which are what the Local Geologist most needs, both to encourage and enlighten him. That an Association like the present was much needed, is perhaps quite enough proved by the fact that, within six weeks after the first private meeting had been held, by a few gentlemen, to talk over the proposal, and without any recourse to the ordinary means of attracting public attention, no less than 150 gentlemen sent their written request to be enrolled as Members many of them well known in Geological Science. So far, the success of the attempt far exceeds the most sanguine expectations of the founders of the Association. It remains necessary to its success, that what it pro- poses to do shall be well understood, and carried out with spirit and perseverance. And here I will glance at a point to which I should not have thought it worth while to allude, did I not know that, even among the wise and good, there are some timid men, who will be needlessly afraid, at times, that there is a ghost behind the chair. It is really quite past the time when there was any need for dwelling on the avowal, that such an Association as the present has nothing to do with "theories of the earth." Were it not that certain informa- tion has reached me, that there do exist benevolent ghost- seers who have already begun to grow pale, I should not have thought it necessary to remind any one that Geo-logy is not Geo-genesy. We have to learn the facts, and to help towards a true generali- zation of the statement of the relations of the facts, that are to be seen on the earth as we find it. We are not about idly to mystify each other with theories of what took place when the earth was " without form and void." Mr. Ephraim Jenkinson put that matter on its true footing, when he sagely remarked to the respectable Dr. * 'The Geologist,' vol. i. p. 301. 8 Primrose, that " the cosmogony, or creation of the world, has puzzled the philosophers of every age." If any member of this Association should attempt to waste our time and wander from our purpose, by dancing through the mazes of so notorious a puzzle, it will be the very simple duty of whoever occupies the Chair which I have now the honour to fill, to remind him that this is not a stage for the dis- play of any theory of the earth's origin that he may happen to patronize ; but that, if he has been so happy as to dig out of this veritable earth, as we actually find it, any of those truths which it is always ready to reveal to the patient searcher, we shall be de- lighted to listen to the story of the finding of his treasures. The aim of the founders of this Association is, that those who, whether from the intelligent interest which the thoughtful man must always take in the phenomena that surround him, or from the professional pursuits in which they are engaged, are in the habit of searching among and handling the groups of facts which relate to the science of Geology, shall find, here, a means of intercommunica- tion, by which the facts gathered up by each shall be continually recorded, and the relations they have to one another, and to former facts, be able to be continually brought forward and tested. It is for those who are thus actively engaged in looking into Nature, that we exist as an Association. It would be doing a great injustice to the number of intelligent men who satisfy the natural curiosity of the student, by supplying him with specimens for scientific study, if we interfered, in any way, with the mercantile demand that the study of Geology has raised for fossils and rock minerals. The result will, unquestionably, be the reverse : for the extension of the sound study of every subject, always extends the demand for all the means to that study. But it is necessary that no mistake should exist as to the fact that this Association has not the least idea of keeping stores of specimens, to be distributed to its members. Its printed proceedings, besides announcing every fresh finding of hidden treasures, will record every communication received from those among our Members who desire to exchange specimens of one For- mation, with which their locality happens to abound, for specimens of other Formations with which they have not the same means of becoming familiar. It will thus be a most valuable assistance to the active collector. The line thus drawn is, however, well marked. 9 It may happen that some of those who deal in Illustrations of the science may join our Body ; for, happily, there are many who have thus become instrumental in the diffusion of the means of scientific study on account of the love they bear to science. But their be- coming members of our Body will unquestionably be notwithstand- ing, and certainly never because of, this incident of their occupation. "We propose indeed to establish a Museum : but we have no idea of filling our cabinets with the sweepings of the over-crowded cabinets of old collectors. The collections which now exist at the British Museum, and in Jermyn Street, already belong to us all. They have been paid for by our money, and their curators are maintained in their several posts, in each, for our behoof. This Association will be the means of making the value of each of those collections more known than they now are; and thus the labours of those whom we pay to fulfil their duties there, and to whose active assis- tance we are therefore entitled, as matter of right, will, by-and-by, become more appreciated ; but we have no intention of repeating the folly of filling cellars with valuable specimens which are only accumulated to be hidden. We intend to collect as strict a series of type specimens of each Formation as we are able ; and to confine our own cabinets to such a series of type specimens. We hope that, while specimens of all characteristic rocks will appear in their most instructive forms, we shall have the corals and the trilobites of the lowest ocean-bed Formations, together with a full set of those Tere- bratula which tell the pretentious parvenu who boasts himself of the Battle Abbey Roll, within how very little a compass is contained the only real aristocrat that is to be found in nature. Though one whose name we all affectionately respect,- I think I may say as much of such a man Hugh Miller, is no longer among us, we hope that the Old Red Sandstone may be illustrated by its Ptencthys and Cephalaspis, and by those beautiful corals which distinguish it from other Formations. The Mountain Limestone none of us can mistake, if we limit it to a few forms among the encrinites, and to the very characteristic shells which it yields in such perfection. In the Coal layers we shall have more difficulty : for where does the material end ? Not to mention any other of the forms of past life which it yields, can you wander by a pit's mouth, nay, can you take up a piece of coal to put it on the fire, or raise a handful of ashes from B 10 beneath the smouldering grate, without finding material for delight- ful study and most instructive observation ? In the Magnesian Limestone and New Red Sandstone we are less likely to be in- volved in difficulty on this score. But in the Lias and the Oolite rich in treasures of all kinds the hoe and the rake must be un- sparingly used, or our cabinets will soon get overrun with weeds. The Wealden will not overcrowd us ; and should we obtain the en- tire head of an Iguanodon, we shall not object to find a place for it. The chalk, though so abounding in stores of fossil wealth, will be less difficult to deal with than many other formations, as regards type specimens ; for no one can mistake its most characteristic and beau- tiful group the Ventriculida, or the more marked forms of its representatives among the oysters, chambered-shells, and star-fish, not to mention now any other of its very beautiful forms. The Ter- tiary, in its so markedly different layers, with its own fruits and its shells and its mammals, as well as its numerous forms related to the de- nizens of the earlier earth, will give more trouble ; while the highly interesting Diluvial Beds which^verlie it, are rich in an abundance from which we shall, however, with less difficulty, be able to select a few to serve as types. Be the difficulties which we shall thus altogether encounter what they mayi our hope is, that we may be able, by degrees, to form a Cabinet which shall be truly typical in its character ; and our intention is, that, while we give the means of constant intercommunication between observers in different parts, and so promote the exchange of specimens between our members, what we retain, as the property of the Association, shall be limited to groups that will always be instructive. I am happy to be able to say and I hope that this will be accepted as an acknowledgment of several communications that we have already received, from distant Members of this Association, offers of sets of fossils that will illustrate several of the main For- mations. It is our belief that every member will, from time to time, come across facts that will be interesting to the others ; and that, by the unconstrained statement of these at our meetings, and recording them on our printed minutes, comparisons may be made, by actual workers in the field, that will equally throw light upon a correspon- dent's questions, and instruct all those who are desiring to get at 11 an actual knowledge of the sort of facts, upon the accumulation of which the science of Geology must be entirely built up. And here I am led to a branch of the subject from which, though I touch on it with some unwillingness, I do not wish to shrink ; for I am convinced of its very great importance. I mean the wretched pedantry that disfigures so much of modern so-called science, seek- ing to cover superficialism by a pompous show of unmeaning words. I do not hesitate to say that one of my own strongest reasons for hailing the suggestion for the formation of this Association has been, that it is quite time that Englishmen, when they deal with science, began to talk English, and ceased to grimace in an unintelligible jargon. It is well enough perhaps, at any rate it is politic, in those countries where true humanity is dead, and where the very breath of human self-respect and freedom is regarded as a pestilence, that great pretensions should be made of State honour done to science. True science is dishonoured, not exalted, by a policy so selfish and so transparent, though, unhappily, so successful. The greater the halo of mysticism and pretence that can be thrown round science, the better the end of the enslavers of the human mind is gained ; for they know that, the more intricately they thus succeed in wrap- ping the toils of a mock intelligence round the minds of men, the more easily will they succeed in keeping them from being engaged with the worthy thoughts that ennoble the MAN. " Mere memory is sought to be developed at the expense of understanding, free thought, and creative power; and thus are instilled passive obe- dience and blind submission on all political- and religious subjects." It is thus that the young Prussian is taught to imagine himself educated, and there are some in England whom the delusion of words is unhappily able so to blind that they hold him up and call him educated, because he is, at a given age, drilled up into a ma- chine capable of no end of parrot repetitions, out of the "isms" and the " ologies " while, of that which alone constitutes real edu- cation, the education of the man, for the duties of life, as the free citizen of a free state, he is carefully kept in hopeless dark- ness ; and there is no country in Europe where this last and only worth-having education is, in any sense or manner, given, except England. Bat what thus marks the crafty systems of miscalled 12 education, as applied to the masses, extends its effects to those who follow out the higher branches of science. Not perceiving the snare into which they fall, too easy victims, they play into the hands of the enemies of human thought and human freedom. What ought to be Science is made into Mystery. And there is far too great a disposition to follow this example, (often, perhaps, unconsciously,) in England. This is particularly shown in the language and style that are adopted. I purposely forbear to quote examples : but it must be familiar to every one of you that you can hardly take up a so-called "scientific" book without finding it so interlarded with phrases and words which never were English, and which bear no intelligible meaning, that science is made repulsive, instead of at- tractive, by those who profess to be the masters of it. True science can be no mystery. A Faraday does not think it beneath his dignity to give popular lectures, on the science which he has illuminated, to a Christmas audience. We do not live in an Egyptian age, when a few self-assuming priests shall have one lan- guage which is to be understood only by the initiated, and another which they condescend to employ in converse with the common people. We live in an age w r hen the boast is paraded that science and art are applied to every purpose of common life. Then, Gen- tlemen, it is high time that science and art shall be taught in the language of common life, and not be smothered by a jargon which is as repulsive to good taste as it is obstructive to the spread of knowledge. The ridiculous jargon into which what is miscalled scientific phraseology has got, latterly, to run, is wholly without ex- cuse. It is not Latin and it is not Greek : nay, it is generally as unintelligible to those familiar with both those languages as it is to any one bred only in the vernacular, and often even more mislead- ing to the former than to the latter. It is certain that it is not English. We inherit a language more copious than the Greek ever was, and one which is peculiarly adaptable for the compound- ing of words ; and which, therefore, may be most readily moulded to the expression of new forms of fact and thought. The man who is unable to express, in English, whatever he has of science to teach, stands confessed as simply unready, and as making pretensions to what does not in truth belong to him. Instead of being a man of real science, he is a charlatan, who seeks to disguise the ignorance 13 that he feels, by an attempt to throw,, under cover of fine phrases, dust in the eyes of those who listen to him. It is time that we put off charlatans, as the object of our worship, and took to knowledge as a thing worth following. When this is done, intelligent men will not tolerate a man who cannot express his ideas in English. Every one will feel that the man is an Impostor, and not a man of science, who, if he pretends to have anything to tell, cannot say it in language intelligible to every man of ordinary education, instead of wrapping it up in an unintelligible jargon. It was well said of one of the old Philosophers of Greece, that he, the first, brought down Philosophy from the clouds, and gave it a home in the dwellings of men. We want a Socrates now as much as ever ; and if this As- sociation does any good, not its least claim to respect will be, that it will compel men who pretend to be scientific, to talk less bad Latin and worse Greek, and to try, at least, what they can make of English. For the use of the unmeaning jargon which, upon the principle Incus a non lucendo, has thus, of late years, come into fashion as "scientific," that is, to hinder science, there cannot be the pre- tence raised that it is a " universal language." The science of Englishmen is wanted in England, not in France or Germany. It were no excuse, therefore, for using a jargon which is certainly not intelligible in England, even though it were intelligible in France and Germany. But it is no more intelligible there than here. It is purely a repulsive and fantastical pedantry everywhere; and it is above all things necessary that those who really value science, and desire its diffusion, and wish well to the spread of knowledge, should have the courage to denounce, in the strongest manner, as I feel it my duty, in delivering an Inaugural Address to this Association, most emphatically to do, this most monstrous of the abuses which disfigure the literature of our day. Certain " terms of art," as they are properly called, must always be in use. This is but another form of " idiom," and has no affinity with the jargon of which I have been speaking. Though one who has paid no attention to Geology may not be aware, on the moment, of the sense in which the words " fault " and " dip " are used, in regard to the layers of the earth's surface, each of those words con- veys, at once, some idea to the hearer's mind ; which a few words of explanation are enough to make him never forget how to apply to the instances in which the word is used by the Geologist. There is no matter of science which might not be equally illustrated. If language was given to man, as the great diplomatist declared, to conceal the thoughts, certainly the modern so-called scientific world is very successful in the fulfilment of the end. There is an older and wiser authority who tells us that it is the place of careful art to conceal the show of art. It is plain that this authority is one of those Classics that has not come within the " humane letters " of those who use the barbarous jargon under which what ought to be science is now so often hidden in impenetrable darkness. It will be well understood that I do not now allude to the at- tempt at a universal language in Classification. That such a uni- versal language should be used, if possible, for this purpose, is highly important, in order to secure the identification of objects. By all means let Latin be made the chosen vehicle. But it is de- sirable that there should be some consistency even here. Names newly given should always be descriptive descriptive of the class, and distinctive of the particular group to which the individual be- longs. Instead of this, how often do we find names given just to save trouble to the slovenly namer which are formed by an unpro- nounceable compound of the name of some obscurity whom it is sought to rescue, thus, from the oblivion that all such vanity deserves. I shall not be suspected of favouring, in these remarks, the notion that any man who pretends to follow science, may make what changes he likes in names and classification. There is a morality in science as well as elsewhere. No one has a right to disturb or overlook the arrangement given, after full investigation, to a group of objects; unless he who assumes to disturb it can and does produce reasons and proofs that the arrangement thus already given is founded on mistake or untruth. A name once given to an object unnamed be- fore, provided it be a real, that is a descriptive, name, remains the name by which scientific men ought thenceforth to know it. Else, there would be no end to the confusion that would arise. Examples enough and too many might be given, of the confusion which has arisen through the neglect of so sound a rule. This rule is, however, subject to the condition that, if it is shown that the, name first given has been given under a wrong impression of the relations of the 15 object, when those relations have been further studied, and proof is given that the true position of the object is thus better known, it will be necessary to range it in its proper group and place ; which may often require that the generic, and sometimes also that the specific, name that has heretofore distinguished it, shall be changed. It has been thought, in forming the present Association, that many who have opportunities of collecting geological illustrations, will be thus induced to go out into the field, to whom the stimulus to this effort has hitherto been wanting. It may not, therefore, be out of place if, besides offering a warning against falling down in worship before the barbarisms of modern so-called science, I make a few remarks as to the material methods that may best be adopted in the collection of specimens. I shall speak of nothing which I have not myself found, as a collector in the field, to be the most useful. The hammers which I have found the best in use are those manu- factured by Messrs. Knight of Poster Lane, in the City of London. There is one of these in particular, which I take to be the most handy and useful hammer that has been yet devised. Messrs. Knight know it, I believe, as Percival Johnson's hammer. It com- bines, in one convenient shape, the pick, the hatchet, and the ham- mer. For the chalk this hammer is invaluable. But it is no less so in working at many other rocks, especially when they are fresh cut, and unhardened (as many soon become) by the weather. Nothing could be better in getting those nearly the most beautiful of geological specimens, the slabs of Dudley limestone. Of course, in working harder and more massive beds, the simple hammer and the chisel must be used. The best sort of hammer in the latter case, is one that is square at one end, and cut down equally on two of its sides to a narrow edge at the other end. In packing fossils, a mistake is often made, which has spoiled many a good specimen. I allude to the use of cotton-wool. There cannot be a greater mistake. It is pretty well known that, of the most delicate fossils of the chalk, I have, in my own cabinet, the largest collection that exists. The whole of these, with very few exceptions, were got out of the rock by my own hand, and brought home, over long distances, through ground where no railway eased the dangers that beset the carriage. Yet I believe that I never found a specimen damaged in the carriage home. The first rule is, 16 . always, if you can, to get out the rock on both sides, that is, the fossil and the impression of it, when it is a delicate specimen : then tie these two together, strongly and tightly, and wrap the whole in firm, but not too thick, paper. If you cannot get both sides, still avoid cotton-wool as you would the plague. It sticks to the damp fossil, and can never be entirely removed, and it does not pro- tect it at all. Even where such a fossil as a tooth, jaw, or other brittle specimen, is got out quite free from the rock, the only way in which cotton- wool can be safely used, is for you first to wrap the fossil in silver paper, and then enclose it, very loosely, in a soft layer of what is called the " medicated" cotton-wool.* In all other cases, take a piece of paper, Hugh Miller used to say that there was nothing like a Conservative Newspaper to wrap fossils in, and wrap it upright, and tightly, round the edges of the fossil, the latter being held at a right angle to the paper. The fossil is thus enclosed in a paper tube, touching it only at the outer edge. Close this tube, in one fold, flat and firm, at the bottom. Draw it gently over at the top, and fold it down, leaving as much of a hollow as you can, close over the face of the specimen. Pack all your specimens closely, side by side, in chip boxes. Of course the heaviest must be put at the bottom. The paper will then be stiff enough to bear a double row without injury, and elastic enough to ensure the whole safe from any injury through the shake of travelling. When you get home, place each on a clean stone, and gently but thoroughly syringe the face of each with clean soft water, applied with a fine garden syringe. Most specimens will come from under this process in a state you would not deem possible ; every edge sharp and clear, and structure plainly seen which you will search for in vain if you do not adopt the method which, from large experience of its use, I recommend. The less delicate fossils do not need such care. But all should be wrapped in paper, with enough folds to save them, by the elasticity of the paper, from injury through the rubbing, in carriage, of one against the other. If a fossil is got from the seacoast, always soak it for a couple of days in soft water, frequently changed. Then bake it in a slow oven, till it is thoroughly dry. You will thus save it from that action of the salt which has ruined so many a * The "medicated" cotton-wool is the common cotton-wool carded out and freed from the lumps and knots which are found in common sorts. 17 beautiful specimen. If you see bones or other promising marks at the edge of a broken piece of rock, collect all the pieces you can where it is found ; place them in their proper positions, bedded in plaster of Paris, on a tray, or in a box ; then clear away from one of the surfaces, till you come down to the face of the fossil of which the broken edge showed the section. Such specimens, when thoroughly cleaned, and bone specimens in general, will be both strengthened and greatly improved in appearance by being washed with gelatine, which is readily done with a large and soft camel's-hair brush. If a fossil is found broken, or breaks in carriage, nothing is easier than to mend it. Get the pieces perfectly clean and dry. If it is lias or oolite, or other hard rock, use thin hot glue, applied to both surfaces, and these will join perfectly. Never use "cement" of any sort. If it is chalk, it requires that, before using the glue, the dry chalk should be well saturated with thin gum or gelatine, or very thin glue; otherwise the pieces will not hold together long; for the glue, when hard, fastens on to only a thin coat of the chalk, which has so little of binding hold to the rest of the body of the chalk, that it will, with a slight force, come away. Many fine speci- mens in the British Museum are seen in this state. At the pits and cuttings, there are often very intelligent men who may be readily taught to know the kind of fossils of which you are in search. Such assistance affords a much more desirable resource than the " dealers" who, entirely uninformed, sometimes spring up in such neighbourhoods. As to the latter, you must always be on guard. The most ingenious devices are had recourse to by them to mislead the unwary. There is a well-known case of a sheep's jaw in chalk being offered for sale by such a dealer. Always look with suspicion on very fine-looking specimens of star-fish, cidaris with spines, ophiura, pentacrinite, etc. Even fishes are not diffi- cult to manufacture. But you must not despise such dealers. You may sometimes get a valuable specimen through their hands, though distorted by the ignorance of the dealer. I obtained, thus, the large limb of the pterodactyle from the chalk, which Professor Owen has figured ; but which, when it came to me (having been broken in getting it from the rock), had the parts displaced in a most pre- posterous manner. The finest specimen of a spine of the Chalk Sharks which I have ever seen, was obtained in the same way, from 18 a dealer. I saw it had been patched : I soaked it in water, so as to separate the patched-up pieces, and found that the end had been put upside down in the middle, and the middle wrong way upwards at the end ; and these ridiculous blunders had been made, notwith- standing that, when it had been well soaked, and the loose chalk all cleaned away, the pieces fitted exactly together in their right places. Tricks of the same sort will be found in Lias specimens, and those from other formations. It will save much labour if specimens are cut down, before pack- ing, to the smallest size. This requires a knack, and is by no means so easy as may seem. The schoolboy thinks that the carpenter's plane works along almost by itself; he tries his hand, and finds out his mistake. So, to see an experienced hand split a pebble, or chip off a flint, looks very easy indeed. Try it, and the fact is found very different. Description, in a few words, is almost impossible. I will only say that, to chip down a flint, you must use a hammer not too heavy, and must give, with the square end, a short, quick, light blow, struck rather sloping outwards. If you are handy in this, you will thus get slice after slice with the greatest ease. If your object is only to lighten the mass, it is soon done. If you want to examine the flint, you can thus get chips thin enough to examine with the microscope. A vast number of beautiful fossils are found, in many different sorts of rocks, both limestone and sandstone, in the inside of mo- derately sized rounded masses or pebbles, but not water-worn of a more or less oval form. It may be worth making a remark, as to getting to the inside of these, which will be found universally appli- cable as to them, and to be of nearly the same value in flints and fragments of rock. Such masses, whether loose pebbles or in rocks, are formed by that holding together of like to like which you may see every day showing itself more or less strikingly in water, quicksilver, and numberless other forms. The attraction is between the particles of the same material. If uriinterfered with, every mass would be round. But if a long leaf gets enclosed in a forming mass, it inter- feres with the attraction of like to like, and this attraction goes on round the edges of the leaf instead of round the centre ; and so the body becomes flattened and oval. Another consequence follows ; namely, that, where the leaf has fallen, the lime- or sand-stone has 19 much less fast a hold than between the parts where like has touched like. Consequently, a blow, rightly given, is quite certain to open to you the enclosed fossil, as clean as the oyster-knife does the oyster. Give your blow generally at the end, in the longest diameter of the pebble ; and never with the square head of a hammer, but with the narrow edge, so that your blow shall fall on one line. The following this hint may save many a fossil from hopeless breakage. Though there is no such certain guide in many flints, there is generally some- thing to give a hint ; and you may always be sure that, be it flint or any hard rock, the least hold-fasting, and therefore the most certain line of breakage, is in the direction where a fossil lies. Thus 1 found in the middle of a large flint, without any outward mark, one side of a whole jaw, full of teeth. How wide the range is where the search has to be made for those facts which this Association hopes to gather together, it were im- possible for me now to enter on. We have already enrolled members in Peru, in Chili, and elsewhere abroad, besides those scattered over England. The variety of kind and condition, both of organic re- mains and of rock, is so great, while knowledge on every one of them is valuable, that it is to be hoped that the different loca- lities will be well worked up for what each is capable of yielding. We do not expect to turn up in England the entire body of a mam- moth, with flesh and skin and hair, as was, fifty years ago, dis- played to the marvelling eyes of men in Siberia ; a discovery that cannot but remind one of that old legend of our forefathers' faith, according to which, long before man lived on the earth, the huge beast Audhumla lived, and sustained her life by licking the rime- frost from the primeval salt rocks. But from the Mammoth and the Mastodon, whose remains, though less complete than in Siberia, are in fact widely found in England, to the numberless but not less wonderful little creatures which can be seen only by aid of the microscope, the variety is wide. I remarked, at the beginning, on the need there is to distinguish between false facts and true ones. This can only be done by noting every circumstance in the conditions and relations of each. It is, first of all, necessary for every man who really loves truth, to be firmly persuaded that he has no right to be a quack : he has no right to pretend to search nature, unless he has first mastered the 20 principles on which the idea of the UNITY of Creation rests. There is not such a thing as Solitude in nature. As freedom and free institutions do not consist in every man doing exactly what he likes ; but in every man knowing and remembering that everybody else has equal rights with himself, and in those equal rights being equally respected by all ; so, all the facts of every branch of science are more or less intimately related to each other ; and, unless the Rela- tions of every alleged fact be well considered, the statement of it will turn out to have been, not the statement of a truth, but of a false fact, one which will be delusive and misleading, instead of leading on to further truth. I can illustrate this highly important point by a few instances, that touch the relations, as well between different remains of animal life as between the conditions of parti- cular animal remains and rocks, and between different rocks. Some years ago, I found, in what seemed, superficially, the solid wall of a familiar chalk-pit, about thirty feet from the top, a horse's tooth. The naked fact was, a horse's tooth found in the chalk. If I had been content to stop there, I might have announced indeed a grand discovery, as everybody knows that such a fossil had never yet been found in such a place. But I knew that the fact which seemed thus naked, was extremely unlikely to be a real fact, being contrary to the Unity of Science, so far as this has yet been ascer- tained in regard to such a matter. So, instead of glorifying myself on the discovery of a horse in the chalk, I went to work to prove that it was not a true fact at all. And I succeeded. The chalk seemed solid enough; but, by careful examination, I became thoroughly satisfied that there had been a crack in the chalk bed, reaching up to the surface of the earth ; and that this tooth which I still show in my cabinet to warn the too eager discoverer had, in the course of ages, got washed down through this crack, though the latter was imperceptible without close search; and had so become lodged where I found it. This is an example of the relations between a fossil and the rock in which it is found. Let me take another example, and this shall be one of the re- lations between one form of animal life and another. All who are familiar with the chalk, know that different shapes of the oyster are very common in its beds. These vary much. On the varieties I can- not now enter. But no one has long worked the chalk without 21 meeting with specimens of the oyster wherein the outside of both shells is strongly stamped with a mark as if they had been sealed with some regular figure of the diaper fashion. You have the two shells. You think you have all that is needed ; and I have often been amused to see how collectors have been puzzled to make out what this mark can be. The explanation is, in fact, as plain as possible. There exists, in the chalk, a very remarkable group of fossils, called the Yentriculidse, distinguished by a structure which was only discovered a few years ago, and the discovery of which showed that mathematical forms are not unknown in animal life, as had been before supposed.* Though these fossils are, as we find them, very delicate, it has been proved that, when living, their forms were not only durable, but particularly firm. Now, the oysters, many of which were, in truth, but parasites, were very fond of settling their young on these Yentriculidee. Some of the oysters, after making a small fixed bottom of shell, throw up a rising wall ; others creep, so to speak, with their shell along the surface of whatsoever it may be that they are first fixed to. Those of the latter that are fixed on the sides of the Yentriculidae, fasten them- selves with closeness to its shape, and follow all its indentations. The new shell is formed, in both valves, just beyond the edge of the animal within, so that both valves which are then of the finest thinness take the same impression. Though the animal afterwards grows, and layer after layer is added to the shell as the animal does thus grow, so that the valves become thick, and the inner surface of each valve becomes quite smooth, the outer surface of the shell bears for ever, on each valve, the stamp which was first thus got. The last example shows that even an actual fossil often cannot be understood unless the nature of others be also understood. But it is no less certain that a mere mass of rock may itself be directly suggestive, and may open to the observer glimpses of something be- yond what he yet knows ; thus still teaching that each fact that can be found is related to facts beyond its mere self. Let me take one example to illustrate this. At the bottom of the London Clay you find what are called "Plumpudding Stones;" which are, indeed, amazingly like plum -pud dings, with the small difference that they * See " The Ventriculidse of the Chalk ; their Microscopic structure, affinities, and classification," etc., by Toulmin Smith. 1848. 22 would be very awkwardly trying to the teeth. Above these is the London Clay: below is the chalk. What story do these stones tell ? They make it plain that, between the deposit of the chalk and of the London Clay, times and ages elapsed of which some ac- count ought to be attempted to be given. Mints have been washed out of the solid chalk ; and these have been rolled on some ancient shore till they have become discoloured and rounded. That shore has afterwards become a deep sea-bed; and these pebbles have become cemented together by a natural cement which is actually harder than the flint itself. Ages have passed on ; and the rock thus formed has itself been upheaved, and broken into fragments ; and these broken fragments have themselves formed the pebbles of some later shore, which had been rolling to and fro, and had done its work, and again sunk beneath the deep sea, before the oldest of the London Clay began to be deposited. Here, methinks, we see an outline Table of Contents of a wonderful time; of which all the chapters are at present lost. Perhaps we may recover some of them. I give the illustration to show how much of a story a single pebble may carry within it, if looked at with reference to those re- lations which necessarily belong to it. In using the microscope, every one knows how often it happens that the casual gazer declares himself unable to see what the careful investigator sees clearly before him. The reason is plain. The one comes all unprepared with any previous knowledge of the Relations of the things belonging to the class of object. The other looks at every object aided by the light of that impression of Unity which long and frequent previous study of related objects has made a living part of his active intelligence. The Law of Unity, namely, that everything we can find has its relations to something else, and is but one form of illustration of a wide-spread principle, is the light by which every fact of Geology, as of natural science in every branch, must be studied. One man looks at a strange creature taken from the ocean, and sees in it a marvel, which is so wondrous that he makes out of it a supporter to the heraldic device of the nation that boasts herself Queen of the Seas. Another bethinks him, while he looks curiously at the same creature, that the Law of Unity does not deal in monsters, even to support the honour of the British name ; and he sets to work, 23 with saw and chisel, at an equal distance on the other side the mid- line of the skull, and lo ! he finds the fellow-tooth of that which, having enormously outgrown its fellow, men have wrongly called the Unicorn. It is, then, a careful search after the RELATIONS of every fact, that alone can enable any fact to be safely asserted as a true one. Men had seen rocks and fossils long before the time of Lyell : but it may be said, with thorough truth, that it was Lyell's putting forth, and giving proof of, the proposition that the changes that are to be seen on the earth's surface are due to causes now in opera- tion, that first made Geology a Science ; and thus established one point of Unity which everything else has since clustered round and illustrated. And it seems to me that the very remarkable series of observations recorded by Mr. Eainey, of St. Thomas's Hospital, in his late work " On the mode of formation of shells of animals, of bone, and of several other structures, by a process of molecular coalescence demonstrable in certain artificially-formed products," heralds discoveries equal in importance, while similar in kind, to the great truth which Lyell first put forth. The reverent sense of admiration which contemplates Unity and design and order in all things, is a far nobler sense than that mere vacant Wonder which sees, indeed, a marvel, but understands it not, and is afraid to try to understand it. The mere looker at the solitary naked thing which he calls a fact, is but an Idiot by the side of him who knows that every individual thing he sees is the illustration of some far wider fact some UNITY in nature, which makes it necessary for him to turn the illustration over and over in every possible shape, if he would hope to get at any true light, and to be anything other than a vacant wonderer or a hollow theorizer. But I have detained you too long. Let me only add that, if this Association is to become a useful means in the progress of the science whence we take our name, it must be by its members put- ting, one and all, their shoulders to the wheel. Our very basis rests on the giving of a united effort for a common end. It is not any two or three of us that can carry the work out. For myself, unex- pectedly asked to take this Chair, I have only consented to do so because I would not be backward to help in what I believe to be a good work ; but I can only do it with the avowal that my engage- 24 meuts, far removed from following out a science which I love, make it impossible for me to bestow on it the time I wish. So far as I am able, I will not be found wanting. There are many here far abler than I am to give the aid that is needed. Let me call on each to do what he is able towards collecting well-investigated facts ; and to bring these before us, so that we may compare them, and, after a fair sifting, add them to the common stock of human know- ledge. We shall thus accomplish a work, the value of which will soon become felt, and which will satisfy ourselves and those who are watching us a few with jealousy, but most with hope that " The Geologists' Association " has not been formed in vain. 14 DAY USE RETURN TO DESK FROM WHICH BORROWED EARTH SCIENCES LIBRARY This book is due on the last date stamped below, or on the date to which renewed.
