Let us now examine some effects of uniting metals by fusing them together into what are called alloys; and, second, the direct influence of a minute quantity of one metal in changing the mass of another in which it is hidden, and causing it to behave in a different way in relation to light, and consequently to possess a colour different from that which is natural to it; or the added metal may so change the chemical nature of the metallic mass that varied effects of colour may be produced by the chemical combinations which result from the action of certain "pickling" solutions. This portion of the subject is so large that I can only hope to set before you certain prominent facts.1 First, with reference to the colour produced by the union of metals. Here is a mass of red copper, and here one of gray antimony: the union of the two by fusion produces a beautiful violet alloy when the proportions are so arranged that there is 51 per cent. of copper and 49 per cent. of antimony in the mixture. This alloy was well known to the early chemists, but unfortunately it is brittle and difficult to work, so that its beautiful colour can hardly be utilised in art. The addition of a small quantity of tin to copper hardens it, and converts it, from a physical and mechanical point of view, into a different metal. The addition of zinc and a certain amount of lead to tin and copper confers upon the mettal copper the property of receiving, when exposed to the atmosphere, varying shades of deep velvety brown, characteristic of the bronze which has from remote antiquity been used for artistic purposes. But by far the most interesting copper alloys, from the point of view of colour, are those produced by its union with zinc, namely brass. Their preparation demands much care in the selection of the materials, and I might have borrowed from the manufacture of brass instance after instance of the influence of traces of impurity in affecting the properties of the alloy, but it is unnecessary to dwell upon this alloy in Birmingham, for in all that relates to the mechanical manipulation of the alloys of copper with tin and with zinc, you are masters. I have many inducements in this place to speak about this beautiful alloy. I am proud to be a namesake of the craftsman, William Austen, who, in 1460, made that magnificent monument in brass which covers the remains and commemorates the greatness of Richard Beauchamp, Earl of Warwick, and I am glad to remember that Queen Elizabeth granted the first patent for the manufacture of brass in England to William Humfrey, Assay Master of the Mint, a predecessor in the office it is my privilege to hold. I want, however, to direct your attention to-night to some alloys of copper with which you are probably less familiar than with brass. In this direction Japanese art affords a richer source of information than any other. Of the very varied series of alloys the Japanese employ for art metalwork, the following may be considered to be the most important and typical. The first is called "shaku-dō"; it contains, as you will observe from Analyses I. and II., in Shaku-do. varieties of it, but in both these alloys, shaku-dō and shibuichi, the point of interest is that the precious metals are, as it were, sacrificed in order to produce definite results; gold and silver, when used pure, being employed very sparingly to heighten the general effect. In the case of the shaku-do, we shall see presently the gold appears to enable the metal to receive a beautiful rich purple coat or patina, as it is called, when treated with certain pickling solutions; while shibu-ichi possesses a peculiar silvergray tint of its own, which, under ordinary atmospheric influences, becomes very beautiful, and to which the Japanese artists are very partial. These are the principal alloys, but there are several varieties of them, as well as combinations of shaku do and shibu-ichi in various proportions, as, for instance, in the case of kiu-shibu-ichi, the composition of which would correspond to one part of shaku do rich in gold, and two parts of shibu-ichi rich in silver. Interesting effects are produced by pouring two alloys of different tints together just at the solidifying point of the less fusible of the two, so that the alloys unite but do not blend, and a mottled surface is the result. These alloys are introduced into almost every good piece of metal-work. Now as to the action of pickling solutions. Many of you will be familiar with the mysteries of the treatment of brass by "dipping" and "dead dipping," so as to produce certain definite surfaces, but the Japanese art metalworkers are far ahead of their European brothers in the use of such solutions. The South Kensington Museum contains a very valuable series of fifty-seven oblong plates, some plain and others richly ornamented, which were specially prepared as samples of the various metals and alloys used by the Japanese. The Geological Museum in Jermyn Street has a smaller, but very instructive, series, of twenty-four plates presented by an eminent metallurgist, the late M. Hochstätter-Godfrey. From descriptions accompanying the latter, and from information I have gathered from certain Japanese artificers now in London, it would appear that there are three solutions generally in use. They are made up respectively in the following proportions, and are used boiling. Verdigris Nitre Lead 'II Iron and Arsenic... traces 99.89 100'01 addition to about 95 per cent. of copper, as much as work That most widely employed is No. I. When boiled in No. III. solution, pure copper will turn a brownish red; and shaku-do, which, you will remember, contains a little gold, the effect of small quantities of metallic impurity as becomes purple; and now you will be able to appreciate affecting the colour resulting from the action of the pickle. Copper containing a small quantity of antimony gives a shade very different from that resulting from the pickling of pure copper. But the copper produced in Japan is the result of smelting complex ores, and the methods of purification are not so perfectly understood as in the West. The result is that the so-called "antimony" of the Japanese art metal-workers, which is present in the variety of copper called "kuromi," is really a complex mixture containing tin, cobalt, and many other metals, so that a metal-worker has an infinite series of materials at command with which to secure any particular shade; and these are used with much judgment, although the scientific reasons for the adoption of any particular sample may be hidden from him. It is strictly accurate to say that each particular shade of colour is the result of minute quantities of metallic impurity, and these specimens and diagrams will, I trust, make this clear, and will prove that the Japanese arrange true pictures in coloured metals and alloys. [This portion of the subject was illustrated with much care by coloured diagrams representing specimens of Japanese art metal-work, by photographs projected on the screen, as well as by the reflected images of small ornaments made of the alloys which had been specially referred to. There was also a trophy of leaves of copper of varying degrees of purity coloured brilliantly by one or other of the "pickles" above described.] There is one other art material to the production of which I hope art workmen in Birmingham will soon direct their attention, as its applications are endless. It is called in Japanese "mokume," which signifies "woodgrain." It is now very rare even in Japan, but formerly the best specimens appear to have been made in Nagoya by retainers of the Daimio of Owari. I have only seen six examples, and only possess a single specimen of native work, and have therefore had to prepare a few illustrations for you in soldered layers of gold, silver, shibu-ichi, shaku-do, and kuromi. FIG. 3. This diagram (Fig. 3) shows the method of manufacture. Take thin sheets of almost any of the alloys I have mentioned, and solder them together layer upon layer, care being taken that the metals which will present diversity of colour come together. Then drill conical holes of varying depth, A, in the mass, or devices in trench-like cuts of V section, B, and hammer the mass until the holes disappear; the holes will thus be replaced by banded circles and the trenches by banded lines. A Japanese artificer taught me to produce similar effects by taking the soldered layers of the alloy, and by the aid of blunted tools making depressions on the back of the mass so as to produce prominences on the front, c. These prominences are filed down until the sheet is again flat; the banded alloys will then appear on the surface in complicated sections, and a very remarkable effect is produced, especially when the colours of the alloys are developed by suitable "pickles." In this way any device may be produced. In principle the method is the same as that which produces the damascening of a sword-blade or gun-barrel, and depends on the fact that under certain The following solder was found to answer well:- Copper 55'5 26'0 18'5 100'0 conditions metals behave like viscous solids, and as truly "flow" as pitch or honey does, only in the case of mokume the art workman has a wide range of tinted metals at command. Throughout Japanese art metal-work, in which I hope you will take increasing interest, there is the one principle of extreme simplicity and absolute fidelity to nature. The brilliant metals, gold and silver, are used most sparingly, only for enrichment, and to heighten the general effect; these precious metals are never allowed to assert themselves unduly, and are only employed where their presence will serve some definite end in relation to the design as a whole. A Japanese proverb asserts that "He who works in gold puts his brains into the melting-pot," meaning, I suppose, that this metal, so precious from an artistic point of view, demands for its successful application the utmost effort of the workman, and suggesting that gold should not be employed in massive forms such as would result from melting and casting, but should be daintily handled, beaten on to the work, or embedded with the hammer. Bear in mind that in Birmingham, when a really fine work is produced in silver, the surface is often made gray by chemical means, "oxidised," as it is termed, and this subordination of the brilliancy of silver to artistic effect, is well understood by the celebrated American firm, Messrs. Tiffany, of New York, who are doing so much to catch the spirit of Japanese art metal-work. All I ask you to do is to carry this still further-to cover base metals with these glowing coloured oxides, and thus to add to the permanence of art work, by producing surfaces which will resist the unfavourable atmospheric influences of our cities. Hitherto we have considered the union of metals by fusion, but fire is not the only agent which can be employed for this purpose. Two or more metals may be deposited side by side by the aid of the electric battery. Birmingham was, as you well know, the early home of electro-metallurgy, an industry to the development of which the great firm of Elkington has so materially contributed. I have no statistics as to the amount of precious metals annually employed for electro-deposition in Birmingham, but it is known that a single works in Paris, belonging to M. Christofle, deposits annually six tons of silver, and it has been estimated that the layer of silver of the thickness actually deposited on various articles would, if spread out continuously, cover an area of 140 acres. I will not, however, dwell upon the deposition of gold and silver in their normal colours. I would remind you that copper and zinc may be deposited by electrolysis so as to form brass, and that all the beautiful bronzes and alloys of the Japanese can be obtained by galvanic agency and further, by suitable admixtures of gold, silver, and copper, red-gold, rose-coloured gold, or green gold may be deposited, so that the electro-metallurgist has at his command the varied palette of the decorative artist. [The images of beautiful deposits of coloured gold, specially prepared by Messrs. Elkington, were then projected on the screen.] I ought to allude to what has been called the moral aspect of colour, and although I cannot follow Goethe in his attributes of colour, which seem to me to be fantastic and over-strained, I quite recognise the poetic sympathy of Shakespeare in making Bassanio select the casket of lead, which contained the warrant for his earthly happiness, because "its paleness moved him more than eloquence." I ask you to remember Ruskin's words, that enjoy colour; it is meant for the perpetual comfort and delight of the human heart; it is richly bestowed on the highest works of creation, and the eminent sign and seal of perfection in them being associated with life in the H.

I wish I had time to point to the great interest and im- NOTES PROF. RÜCKER, F. R. S., has been appointed by the Lord President of the Council to the Professorship of Physics in the Normal School of Science and Royal School of Mines, rendered vacant by the death of Prof. Guthrie, F.R.S. AT the Royal Society on Thursday last (November 25) a paper was read by Sir Richard Owen, containing some further evidence on the structure of the very remarkable extinct marsupial, Thylacoleo carnifex. The author re-affirmed his previous statements that it was a carnivorous beast of the size of a lion, the probable prey of which had been the larger herbivorous marsupials, also now extinct. Prof. Flower, after reviewing the additional evidence that had been adduced, repeated his conviction expressed eighteen years ago in a paper read before the Geological Society, that the dentition of Thylacoleo found no parallel in any existing predaceous carnivore, but was formed on He pointed out that the experiment with minium confirmed his view that he mercury calcined in air derived oxygen from the air. III a totally different type, and that there was therefore no justification for assigning to it habits for which it did not seem particularly well adapted. The essential conditions in a dentition which would enable an animal to seize and overcome large and struggling prey, as seen in both lions, tigers, wolves, and the existing carnivorous marsupials, are large canines set well apart, with incisors so small as not to interfere with their piercing action; whereas in Thylacoleo the canines are rudimentary, and the central incisors greatly developed. The alternative, sometimes suggested, that the animal was herbivorous, was equally improbable. In fact, it would not be safe to do more than speculate on the habits or food of an animal the dentition of which was so highly specialised, and without any analogy in the existing state of things. Prof. Huxley said that he agreed with the conclusions of the last speaker. A COURSE of six lectures, adapted to a juvenile auditory, on "The Chemistry of Light and Photography" (with experimental illustrations), will be given at the Royal Institution by Prof. Dewar, M.A., F.R.S., on the following days, at three o'clock :-Tuesday, December 28, 1886; Thursday, December 30; Saturday, January 1, 1887; Tuesday, January 4; Thursday, January 6; Saturday, January 8. THE Royal Society have just received from Egypt a consignment of specimens of the different strata of soil in the Delta. The borings have been carried out to a depth of nearly 200 feet, and the solid bottom has not yet been reached. The Royal Engineers in Egypt have been intrusted with the work. The specimens, which are chiefly of sand and clay strata, are deemed of great importance, and the Society has granted money for the continuance of the work, which will be carried out by the detachment of Engineers as hitherto. THE Secretary of State for War has given permission for Sir Frederick Abel, C.B., the Chemist of the War Department, to accept the post of organising secretary to the Imperial Institute, provided that the duties do not interfere with those of his appointment under the War Office; and Sir Frederick Abel has been desired by the Prince of Wales, President of the Imperial Institute, to enter upon his work as soon as possible. The new secretary has just completed his work in connection with the electric lighting of the Indian and Colonial Exhibition, and is also retiring from his duties in connection with the Society of Arts. ON November 17, at 7h. 18m. p.m., a fine fireball was seen at Stonyhurst College, Blackburn. It appeared to be several times as bright as Venus. In colour it was violet, and of a distinct pear shape. The part of its path observed, as far as could be judged from the stars seen through detached clouds, was from near Ceti to the small stars above Fomalhaut, about 88 Aquarii. Its path was slightly curved. So brightly did it shine that attention was first called to it by the illumination of the sky, although seen from a room in which the gas was lighted. THE Morning Star of Jaffna, in Ceylon, reports the death of the taxidermist of the Victoria Museum in that town from the bite of a cobra, under very curious circumstances. While feeding a cobra, which he had supposed was harmless from previous extraction of the poison-bag, it suddenly bit his hand. For a few minutes he took no notice, thinking the bite harmless, but pain and nausea soon began. Carbolic acid was applied, ligatures were bound round the arm, an incision was made at the bite, and the blood of the arm was wholly removed. Various antidotes were used, but the unfortunate man lost the power of speech, and soon after every muscle seemed to have become paralysed, and breathing entirely ceased. Artificial respiration was therefore resorted to, and this operation was unceasingly continued for nine hours, when at last the patient made an attempt to breathe, and soon regained consciousness enough to make his wants known. He steadily improved until the Friday, the accident having taken place on a Wednesday, and then astonished those around him by stating that during the severe operation of Wednesday night he was conscious of all that was taking place, but was unable to make his feelings known, not having power over a single muscle. would seem that the poison paralysed the nerves of motion, but not those of feeling, for he could see, and hear, and feel, although the physicians, even by touching the eyeball, could get no response either of feeling or consciousness. His partial recovery was, however, followed by a high fever and inflammation of the lungs, and he died, perfectly conscious, on the following Sunday. It THE New Zealand Government are about to collect salmon ova in Scotland and transfer them to that colony for incubation. It will be remembered that the Royal Commissioner for New Zealand has previously carried out similar work successfully, and it has been found that the S. salar thrives well in the waters of that possession. Last year a large number of salmon ova were collected from Scotland, and hatched out and reared in New Zealand. COMMENCING on January 1, 1887, a journal is to be published by the National Fish-Culture Association, comprising not only information regarding its transactions from time to time, but also articles relative to the subjects of fish-culture, fish, and fisheries. A record will also be given of what takes place in connection with these subjects throughout the whole of the United Kingdom, the colonies, and abroad. A STRONG Shock of earthquake, lasting several seconds, was felt at Smyrna and in the adjacent districts early on the morning of November 27, and news has been received of Tches me and Chios having been similarly visited. felt at Tashkend on the morning of November 29, causing A strong shock was damage to many houses in the Russian quarter. Two shocks were felt on Sunday at Somerville and at Charleston. A slight shock was felt in Cairo at half-past four o'clock on the afternoon of the 17th. The vibration lasted several seconds. DURING the past summer, Dr. Fr. Svenonius, the well-known Swedish geologist, has been prosecuting geological, ethnographical, and glacial studies in Swedish Lapland. On the evening of November 4 a splendid display of the aurora borealis was seen at Throndhjem, in Norway. Not only the northern, but also the eastern and part of the southern, sky were covered with aurora. The radiation was particularly brilliant from south-west to north-east, forming a wreath in all the colours of the rainbow. During October, several splendid displays of aurora occurred, but none as brilliant as this one. ON the evening of October 30 a brilliant meteor was seen from the Faloterbo lightship, on the south-west coast of Sweden. It went in a direction south-south-west to north-north-east, exploding, as it seemed, from time to time, and displaying the most brilliant yellow, red, and green light. At times the sky was illuminated as in full moonlight. About a couple of minutes after the last explosion, reports as of guns were heard. about 2 a.m. of November 5 another splendid meteor was seen at Hamar, in Norway. It went in a southerly direction across Lake Mjösen, and disappeared from view, leaving a long, broad, variegated trail behind. At PROF. COLLETT, the well-known Norwegian zoologist, an nounces that the beaver is now extinct in Northern Norway, [Dec. 2, 1886 but estimates that about 100 are still in existence in the south, chiefly in the province of Nedenaes. A KITCHEN-MIDDEN has just been discovered at Ginnerup, in Denmark, at the foot of a cliff near a dried-up sound. It is about a yard in depth and of considerable extent, and contains quantities of shells of oysters, mussels, &c. THE last numbers of the Journal of the China Branch of the Royal Asiatic Society (vol. xxi. Nos. 1 and 2) contain a "Sym posium" on the question whether Western knowledge, and especially, of course, Western science, should be conveyed to the Chinese through the medium of their own or of a Western language. Fourteen of the leading European scholars in China took part in the discussion. Their views will not bear classifica tion under the heads affirmative or negative, as some hold a middle place, exhibiting a leaning in one direction or another. The general tendency, however, is in favour of exciting the curiosity and interest of intelligent Chinese in the matter of Western knowledge by popular exposition in the native tongue, while reserving a more adequate representation for a time when a sufficient number of Chinese shall have acquired foreign languages to constitute a learned class in our sense of the expression. A further and final stage will be reached when the members of this class, themselves impregnated with foreign knowledge, shall convey it to their fellow-countrymen in their own tongue. lutely foreign to the genius of the Chinese language and beyond gradually modified to suit the exigencies of doctrines now abso its capabilities. mous. IN the course of the discussion, some interesting facts with regard to the translation of scientific terminology into Chinese were mentioned. Dr. Martin, of Pekin, referred to Ricci's old translation of Euclid, which he entitled "The Fundamental Principle of the Science of Quantity." Oxygen, hydrogen, and nitrogen are translated so as to express their character-tics of supporting life, of lightness, and of derivation from nitre. On the other hand, Dr. Macgowan mentions that a translator's difficulties in dealing with natural history terms are really enor He undertook the translation of Dana's " Mineralogy" and Lyell's "Elements of Geology" into Chine e for the Government, and a scientific native scholar was detailed to assist him. When they came to the plants that have the names of foreign botanists, most of them polysyllabic, they were appalled, and as they could only be rendered phonetically, the native scholar decided against translating any portion of the plant's name, transferring it bodily, according to sound, into Chinese. Similarly, the complex nomenclature of organic chemistry pre sents a formidable difficulty. A Chinese clergyman, who took part in the discussion, delivered a particularly interesting address, urging that the phonetic method should, as a rule, be employe l, on the ground that the characters used in the translation of scientific terms have traditional meanings to the Chinese mind, and thus great confusion is created. The "term "-controversy which has agitated theologians in China for the past half-century, and has divided them into two hostile camps, appears likely to revive in the domain of science, the question lying betwee translation or phonetic reproduction. FROM a study of thirty-two years' observations of thunder storms in the Vienna region, Dr. Hann finds that there is a double maximum of frequency. The greatest number occur in the first half of June, the second smaller maximum is in the end of July; between these is a secondary minimum. (Thunderstorms hardly ever occur in winter.) This agrees with observaIn Brussels most thunderstorms occur in the second halves of June and July. The daily period in Vienna shows a chief maximum about 3.20 p.m., and a secondary one at 1.2 a.m. The spring and summer storms come mostly from the east or south-east, and seem to belong to Mediterranean tions in Munich. 1 depressions, coming up from the Adriatic, as those of late summer seem to be on the south or south-east border of Atlantic depressions. BETHNAL GREEN FREE LIBRARY has been doing a large amount of good work in the thickly-populated district in which it is situated, not only by giving facilities for reading books, but by science lectures and science "talks." It is much in want of funds for the extension of operations, and we commend it to the consideration of our readers. The librarian is G. F. Hilcken. THE additions to the Zoological Society's Gardens during the past week include a Bonnet Monkey (Macacus sinicus) from India, presented by Miss G. M.

OUR ASTRONOMICAL COLUMN THE ARGENTINE GENERAL CATALOGUE OF STARS.-This Catalogue, containing the mean positions of 32,448 southern stars determined at the National Observatory of Cordoba, has recently been published by Dr. Gould. The observations from which the Catalogue positions are deduced were made with the meridian-circle of the Cordoba Observatory during the years 1872-80. During these years the zone-observations were the chief object of attention, and the present Catalogue contains the places of those stars whose positions were more elaborately determined during the progress of that great work, and constitute an addition to our knowledge of southern stellar positions of perhaps not less importance than the Cordoba Zone-Catalogue. The General Catalogue gives the positions, for the epoch 1875'0, of most of the southern stars brighter than magnitude 8, the deficiencies in this respect being chiefly found north of the parallel of 23°, at which the zones begin. These omissions will be of comparatively small importance, inasmuch as the new Durchmusterung of Prof. Schönfeld comprises all the southern stars within this region, while accurate determinations of the brighter ones will have been made in the re-observation of Lalande's stars now nearly completed at the Paris Observatory.

THE ROYAL SOCIETY1 FOR many years it has been my duty as senior secretary to read at each anniversary the death-roll of the year. The names this year are perhaps slightly fewer than usual, but many recall to us faces once familiar that we shall never see here again. Earliest among them comes Sir Frederick Evans, whose death took place only very shortly after our last anniversary. In the course of the preceding summer he crossed the Atlantic to take part in that International Conference which assembled at Washington, to deliberate among other things on the choice of a common prime meridian for all civilised nations. On his return he was looking ill, and the illness increased until it carried him away. Yet even through his illness he kept on working at science, at a task he had undertaken, and which was almost completed when he died. To this I shall have occasion to refer again. In Mr. Busk we have lost one who has long been among us, and who took an active part in the scientific business of the Society. He repeatedly served on our Council, and both then and subsequently gave us the benefit of his exten ive knowledge and sound judgment in the important but laborious task of advising the Committee of Papers as to the proper mode of dealing with papers which they referred to him. In Lord Cardwell we have lost a statesman whose political duties did not prevent him from coming among us and serving on our Council. The public services and singular honesty and straightforwardness of Mr. Forster are appreciated by the nation at large. Quite recently, at no advanced age, we have lost Prof. Guthrie, the occupant of a chair which a great many years ago I held for a time; a man whose genial character drew around him a close circle of friends. Still more recently we have lost the Earl of Enniskillen, whose fine palæontological collections are well known to geologists. Only the other day one passed away whom we seldom missed at our anniversary meeting, and who was frequently with us on other occasions: I allude to General Boileau, whose philanthropic labours will not soon be forgotten, and may, I trust, be recognised in a much needed form. 1 The Fellows will have noticed with satisfaction a very con Anniversary Address by Prof. G. G. Stokes, President, on Tuesday, November 30, 1886. |
