Before I proceed to criticise this state of things, I will mention one point on which I am glad to be able to bestow on the Royal Society the highest praise. I refer to the extreme regularity with which the volumes of the Transactions are published. The appearance of the half-volumes at intervals of six months, insures for any communication almost immediate publicity; whilst the shortness of the time between its reception and publication, is a guarantee to the public that the whole of the paper was really communicated at the time it bears date. To this may also be added, the rarity of any alterations made previously to the printing, a circ.u.mstance which ought to be imitated, as well as admired, by other societies. There may, indeed, be some, perhaps the Geological, in which the task is more difficult, from the nature of the subject. The sooner, however, all societies can reduce themselves to this rule, of rarely allowing any thing but a few verbal corrections to papers that are placed in their hands, the better it will be for their own reputation, and for the interests of science.
It has been, and continues to be, a subject of deep regret, that the first scientific academy in Europe, the Inst.i.tute of France, should be thus negligent in the regularity of its publications; and it is the more to be regretted, that it should be years in arrear, from the circ.u.mstance, that the memoirs admitted into their collection are usually of the highest merit. I know some of their most active members have wished it were otherwise; I would urge them to put a stop to a practice, which, whilst it has no advantages to recommend it, is unjust to those who contribute, and is only calculated to produce conflicting claims, equally injurious to science, and to the reputation of that body, whose negligence may have given rise to them. [Mr. Herschel, speaking of a paper of Fresnel"s, observes--"This memoir was read to the Inst.i.tute, 7th of October, 1816; a supplement was received, 19th of January, 1818; M. Arago"s report on it was read, 4th of June, 1821: and while every optical philosopher in Europe has been impatiently expecting its appearance for seven years, it lies as yet unpublished, and is only known to us by meagre notices in a periodical journal." MR HERSCHEL"S TREATISE ON LIGHT, p. 533.--ENCYCLOPAEDIA METROPOLITANA.]
One of the inconveniences arising from having no historical portion in the volumes of the Royal Society is, that not only the public, but our own members are almost entirely ignorant of all its affairs. With a means of giving considerable publicity (by the circulation of above 800 copies of the Transactions) to whatever we wish to have made known to our members or to the world, will it be credited, that no notice was taken in our volume for 1826, of the foundation of two Royal medals, nor of the conditions under which they were to be distributed. [That the Council refrained from having their first award of those medals thus communicated, is rather creditable to them, and proves that they had a becoming feeling respecting their former errors.] That in 1828, when a new fund, called the donation fund, was established, and through the liberality of Dr. Wollaston and Mr. Davies Gilbert, it was endowed by them with the respective sums of 2,000L. and 1,000L. 3 per cents; no notice of such fact appears in our Transactions for 1829. Other gentlemen have contributed; and if it is desirable to possess such a fund, it is surely of importance to inform the non-attending, which is by far the largest part of the Society, that it exists; and that we are grateful to those by whom it has been founded and augmented. Neither did the Philosophical Transactions inform our absent members, that they could purchase the President"s Discourses at the trade-price.
The list of the Officers, Council, and Members of the Royal Society is printed annually; yet, who ever saw it bound up with the Philosophical Transactions, to which it is intended to be attached? I never met with a single copy of that work so completed, not even the one in our own library. It is extremely desirable that the Society should know the names of their Council; and whilst it would in some measure contribute to prevent the President from placing incompetent persons upon it, it would also afford some check, although perhaps but a slight one, on the distribution of the medals. When I have urged the expediency of the practice, I have been answered by excuses, that the list could not be made up in time for the volume. If this is true of the first part, they might appear with the second; and even if this were impracticable, the plan of prefixing them to the volume of the succeeding year, would be preferable to that of omitting them altogether. The true reason, however, appeared at last. It was objected to the plan, that by the present arrangement, the porter of the Royal Society took round the list to those members resident in London, and got from some of them a remuneration, in the shape of a Christmas-box; and this would be lost, if the time of printing were changed. [During the printing of this chapter, a friend, on whom I had called, complained that the porter of the Royal Society had demanded half-a-crown for leaving the list.] Such are the paltry interests to which those of the Royal Society are made to bow.
Another point on which information ought to be given in each volume, is the conditions on which the distribution of the Society"s medals are made. It is true that these are, or ought to be, printed with the Statutes of the Society; but that volume is only in the hands of members, and it is for the credit of the medals themselves, that the laws which regulate their award should be widely known, in order that persons, not members of the Society, might enter into compet.i.tion for them.
Information relative to the admissions and deaths amongst the Society would also be interesting; a list of the names of those whom the Society had lost, and of those members who had been added to its ranks each year, would find a proper place in the historical pages which ought to be given with each volume of our Transactions.
The want of a distinction between the working members of the Society, and those who merely honour it with their patronage, renders many arrangements, which would be advantageous to science, in some cases, injudicious, and in other instances, almost impossible.
Collections of Observations which are from time to time given to the Society, may be of such a nature, that but few of the members are interested in them. In such cases, the expense of printing above 800 copies may reasonably induce the Council to decline printing them altogether; whereas, if they had any means of discrimination for distributing them, they might be quite willing to incur the expense of printing 250. Other cases may occur, in which great advantage would accrue, if the principle were once admitted. Government, the Universities, public bodies, and even individuals might, in some cases, be disposed to present to the Royal Society a limited number of copies of their works, if they knew that they were likely to be placed in the hands of persons who would use them. Fifty or a hundred additional copies might, in some cases, not be objected to on the ground of expense, when seven or eight hundred would be quite out of the question.
Let us suppose twenty copies of a description of some new chemical process to be placed at the disposal of the Royal Society by any public body; it will not surely be contended that they ought all to remain on the Society"s shelves. Yet, with our present rules, that would be the case. If, however, the list of the Members of the Society were read over to the Council, and the names of those gentlemen known to be conversant with chemical science were written down; then, if nineteen copies of the work were given to those nineteen persons on this list, who had contributed most to the Transactions of the Society, they would in all probability be placed in the fittest hands.
Complete sets of the Philosophical Transactions have now become extremely bulky; it might be well worth our consideration, whether the knowledge of the many valuable papers they contain would not be much spread, by publishing the abstracts of them which have been read at the ordinary meetings of the Society. Perhaps two or three volumes octavo, would contain all that has been done in this way during the last century.
Another circ.u.mstance, which would contribute much to the order of the proceedings of the Council, would be to have a distinct list made out of all the statutes and orders of the Council relating to each particular subject.
Thus the President, by having at one view before him all that had ever been decreed on the question under consideration, would be much better able to prevent inconsistent resolutions, and to save the time of the Council from being wasted by unnecessary discussions.
SECTION 6. ORDER OF MERIT.
Amongst the various proposals for encouraging science, the inst.i.tution of an order of merit has been suggested. It is somewhat singular, that whilst in most of the other kingdoms of Europe, such orders exist for the purpose of rewarding, by honorary distinctions, the improvers of the arts of life, or successful discoverers in science, nothing of the kind has been established in England. [At the great meeting of the philosophers at Berlin, in 1828, of which an account is given in the Appendix; the respect in which Berzelius, Oersted, Gauss, and Humboldt were held in their respective countries was apparent in the orders bestowed on them by the Sovereigns of Sweden, of Denmark, of Hanover, and of Prussia; and there were present many other philosophers, whose decorations sufficiently attested the respect in which science was held in the countries from which they came.]
Our orders of knighthood are favourable only to military distinction.
It has been urged, as an argument for such inst.i.tutions, that they are a cheap mode of rewarding science, whilst, on the other hand, it has been objected, that they would diminish the value of such honorary distinctions by making them common. The latter objection is of little weight, because the numbers who pursue science are few, and, probably, will long continue so. It would also be easily avoided, by restricting the number of the order or of the cla.s.s, if it were to form a peculiar cla.s.s of another order. Another objection, however, appears to me to possess far greater weight; and, however strong the disposition of the Government might be (if such an order existed) to fill it properly, I do not believe that, in the present state of public opinion respecting science, it could be done, and, in all probability, it would be filled up through the channels of patronage, and by mere jobbers in science.
Another proposal, of a similar kind, has also been talked of, one which it may appear almost ridiculous to suggest in England, but which would be considered so in no other country. It is, to enn.o.ble some of the greatest scientific benefactors of their country. Not to mention political causes, the ranks of the n.o.bility are constantly recruited from the army, the navy, and the bar; why should not the family of that man, whose name is imperishably connected with the steam-engine, be enrolled amongst the n.o.bility of his country? In utility and profit, not merely to that country, but to the human race, his deeds may proudly claim comparison even with the most splendid of those achieved by cla.s.ses so rich in glorious recollections. An objection, in most cases fatal to such a course, arises from the impolicy of conferring a t.i.tle, unless a considerable fortune exists to support it; a circ.u.mstance very rarely occurring to the philosopher. It might in some measure be removed, by creating such t.i.tles only for life. But here, again, until there existed some knowledge of science amongst the higher cla.s.ses, and a sound state of public opinion relative to science, the execution of the plan could only be injurious.
SECTION 7. OF THE UNION OF SCIENTIFIC SOCIETIES.
This idea has occurred to several persons, as likely to lead to considerable advantages to science. If the various scientific societies could unite in the occupation of one large building, considerable economy would result from the union. By properly arranging their evenings of meeting, one meeting-room only need be required. The libraries might either be united, or arranged in adjoining rooms; and such a system would greatly facilitate the inquiries of scientific persons.
Whether it would be possible to reunite in any way the different societies to the Royal Society, might be a delicate question; but although, on some accounts, desirable, that event is not necessary for the purpose of their having a common residence.
The Medico-Botanical Society might, perhaps, from sympathy, be the first to which the Royal Society would apply; and by a proper interchange of diplomas, [A thing well understood by the INITIATED, both at HOME and ABROAD.] the two societies might be inoculated with each other. But even here some tact would be required; the Medico-Botanical is a little particular about the purity of its written doc.u.ments, and lately attributed blame to one of its officers for some slight tampering with them, a degree of illiberality which the Council of the Royal Society are far from imitating.
The Geological and the Astronomical Societies nourish no feelings of resentment to the parent inst.i.tution for their early persecution; and though they have no inducement to seek, would scarcely refuse any union which might be generally advantageous to science.
CONCLUSION.
In a work on the Decline of Science, at a period when England has so recently lost two of its brightest ornaments, I should hardly be excused if I omitted to devote a few words to the names of Wollaston and of Davy. Until the warm feelings of surviving kindred and admiring friends shall be cold as the grave from which remembrance vainly recalls their cherished forms, invested with all the life and energy of recent existence, the volumes of their biography must be sealed. Their contemporaries can expect only to read their eloge.
In habits of intercourse with both those distinguished individuals, sufficiently frequent to mark the curiously different structure of their minds, I was yet not on such terms even with him I most esteemed, as to view his great qualities through that medium which is rarely penetrated by the eyes of long and very intimate friendship.
Caution and precision were the predominant features of the character of Wollaston, and those who are disposed to reduce the number of principles, would perhaps justly trace the precision which adorned his philosophical, to the extreme caution which pervaded his moral character. It may indeed be questioned whether the latter quality will not in all persons of great abilities produce the former.
Ambition const.i.tuted a far larger ingredient in the character of Davy, and with the daring hand of genius he grasped even the remotest conclusions to which a theory led him. He seemed to think invention a more common attribute than it really is, and hastened, as soon as he was in possession of a new fact or a new principle, to communicate it to the world, doubtful perhaps lest he might not be antic.i.p.ated; but, confident in his own powers, he was content to give to others a chance of reaping some part of that harvest, the largest portion of which he knew must still fall to his own share.
Dr. Wollaston, on the other hand, appreciated more truly the rarity of the inventive faculty; and, undeterred by the fear of being antic.i.p.ated, when he had contrived a new instrument, or detected a new principle, he brought all the information that he could collect from others, or which arose from his own reflection, to bear upon it for years, before he delivered it to the world.
The most singular characteristic of Wollaston"s mind was the plain and distinct line which separated what he knew from what he did not know; and this again, arising from his precision, might be traced to caution.
It would, however, have been visible to such an extent in few except himself, for there were very few so perfectly free from vanity and affectation. To this circ.u.mstance may be attributed a peculiarity of manner in the mode in which he communicated information to those who sought it from him, which was to many extremely disagreeable. He usually, by a few questions, ascertained precisely how much the inquirer knew upon the subject, or the exact point at which his ignorance commenced, a process not very agreeable to the vanity of mankind; taking up the subject at this point, he would then very clearly and shortly explain it.
His acquaintance with mathematics was very limited. Many years since, when I was an unsuccessful candidate for a professorship of mathematics, I applied to Dr. W. for a recommendation; he declined it, on the ground of its not being his pursuit. I told him I asked it, because I thought it would have weight, to which he replied, that it ought to have none whatever. There is no doubt his view was the just one. Yet such is the state of ignorance which exists on these subjects, that I have several times heard him mentioned as one of the greatest mathematicians of the age. [This of course could only have happened in England.] But in this as in all other points, the precision with which he comprehended and retained all he had ever learned, especially of the elementary applications of mathematics to physics, was such, that he possessed greater command over those subjects than many of far more extensive knowledge.
In a.s.sociating with Wollaston, you perceived that the predominant principle was to avoid error; in the society of Davy, you saw that it was the desire to see and make known truth. Wollaston never could have been a poet; Davy might have been a great one.
A question which I put, successively, to each of these distinguished philosophers, will show how very differently a subject may be viewed by minds even of the highest order.
About the time Mr. Perkins was making his experiments on the compression of water, I was much struck with the mechanical means he had brought to bear on the subject, and was speculating on other applications of it, which I will presently mention.
Meeting Dr. Wollaston one morning in the shop of a bookseller, I proposed this question: If two volumes of hydrogen and one of oxygen are mixed together in a vessel, and if by mechanical pressure they can be so condensed as to become of the same specific gravity as water, will the gases under these circ.u.mstances unite and form water? "What do you think they will do?" said Dr. W. I replied, that I should rather expect they would unite. "I see no reason to suppose it," said he. I then inquired whether he thought the experiment worth making. He answered, that he did not, for that he should think it would certainly not succeed.
A few days after, I proposed the same question to Sir Humphry Davy. He at once said, "they will become water, of course;" and on my inquiring whether he thought the experiment worth making, he observed that it was a good experiment, but one which it was hardly necessary to make, as it must succeed.
These were off-hand answers, which it might perhaps be hardly fair to have recorded, had they been of persons of less eminent talent: and it adds to the curiosity of the circ.u.mstance to mention, that I believe Dr.
Wollaston"s reason for supposing no union would take place, arose from the nature of the electrical relations of the two gases remaining unchanged, an objection which did not weigh with the philosopher whose discoveries had given birth to it.
[The result of the experiment appeared, and still appears to me, to be of the highest importance; and I will shortly state the views with which it was connected. The next great discovery in chemistry to definite proportions, will be to find means of forming all the simple unions of one atom with one, with two, or with more of say other substance: and it occurred to me that the gaseous bodies presented the fairest chance of success; and that if wishing, for instance, to unite four atoms of one substance with one of another, we could, by mechanical means, reduce the mixed gases to the same specific gravity as the substance would possess which resulted from their union, then either that such union would actually take place, or the particles of the two substances would be most favourably situated for the action of caloric, electricity, or other causes, to produce the combination. It would indeed seem to follow, that if combination should take place under such circ.u.mstances, then the most probable proportion in which the atoms would unite, should be that which furnished a fluid of the least specific gravity: but until the experiments are made, it is by no means certain that other combinations might not be produced.]
The singular minuteness of the particles of bodies submitted by Dr.
Wollaston to chemical a.n.a.lysis, has excited the admiration of all those who have had the good fortune to witness his experiments; and the methods he employed deserve to be much more widely known.
It appears to me that a great mistake exists on the subject. It has been adduced as one of those facts which prove the extraordinary acuteness of the bodily senses of the individual,--a circ.u.mstance which, if it were true, would add but little to his philosophical character; I am, however, inclined to view it in a far different light, and to see in it one of the natural results of the admirable precision of his knowledge.
During the many opportunities I have enjoyed of seeing his minute experiments, I remember but one instance in which I noticed any remarkable difference in the acuteness of his bodily faculties, either of his hearing, his sight, or of his sense of smell, from those of other persons who possessed them in a good degree. [This was at Mr. South"s observatory, and the object was, the dots on the declination circle of his equatorial; but, in this instance, Dr. Wollaston did not attempt to TEACH ME HOW TO SEE THEM.]
He never showed me an almost microscopic wire, which was visible to his, and invisible to my own eye: even in the beautiful experiments he made relative to sounds inaudible to certain ears, he never produced a tone which was unheard by mine, although sensible to his ear; and I believe this will be found to have been the case by most of those whose minds had been much accustomed to experimental inquiries, and who possessed their faculties unimpaired by illness or by age.
It was a much more valuable property on which the success of such inquiries depended. It arose from the perfect attention which he could command, and the minute precision with which he examined every object. A striking ill.u.s.tration of the fact that an object is frequently not seen, FROM NOT KNOWING HOW TO SEE IT, rather than from any defect in the organ of vision, occurred to me some years since, when on a visit at Slough.
Conversing with Mr. Herschel on the dark lines seen in the solar spectrum by Fraunhofer, he inquired whether I had seen them; and on my replying in the negative, and expressing a great desire to see them, he mentioned the extreme difficulty he had had, even with Fraunhofer"s description in his hand and the long time which it had cost him in detecting them. My friend then added, "I will prepare the apparatus, and put you in such a position that they shall be visible, and yet you shall look for them and not find them: after which, while you remain in the same position, I will instruct you how to see them, and you shall see them, and not merely wonder you did not see them before, but you shall find it impossible to look at the spectrum without seeing them."
On looking as I was directed, notwithstanding the previous warning, I did not see them; and after some time I inquired how they might be seen, when the prediction of Mr. Herschel was completely fulfilled.
It was this attention to minute phenomena which Dr. Wollaston applied with such powerful effect to chemistry. In the ordinary cases of precipitation the cloudiness is visible in a single drop as well as in a gallon of a solution; and in those cases where the cloudiness is so slight, as to require a ma.s.s of fluid to render it visible, previous evaporation, quickly performed on slips of window gla.s.s, rendered the solution more concentrated.
