Many of your projects surpass by their audacity the limits of our immediate comprehension. Thus it has frequently happened in France, a t least in certain circles, t o try t o class such enterprises by saying, “It is American bluff.” But, nothing of the kind. We have t o admit it. The bluff resides merely in our imagination. It is not in yours; you look a t the world in all the boldness of your imagination and you dream of realities which sometimes seem to surpass the possibilities of the moment.

On the evening of October 19, 1917, honorary membership in The Chemists’ Club of S e w York City was conferred upon Prof. Victor Grignard of the French Mission. The ceremony took place a t the regular joint meeting of the S e w York Sections of the Society of Chemical Industry, American Chemical Society and the American Electrochemical Society. Dr. M. C. Whitaker, president of the Club, introduced Dr. L. H. Baekeland who officially informed Prof. Grignard of the action of the Club. 1n.accepting the honor, Prof Grignard replied in French. Dr. Baekeland has prepared a translation of the address, which follows.- [EDITOR.]

The horrible war which has been imposed upon us, has already made a big step in that direction. I n order to save the world from Prussian hegemony, in order t o stop the grasping hand of Germany over every liberal thought and generous instinct, we cannot have enough of the support of the United States alongside that of the European Allies. And this brotherhood of our armies has made indispensable, more particularly between our two countries, the scientific and industrial alliance which is necessary to conduct this war, -a war more scientific than anyone ever might have imagined. Without citing too many examples, our metallurgists have already brought t o you precious improvements in the manufacture of steel; from your side, you bring us a solution. and perhaps two solutions, t o the worrying nitric acid problem. ,&This fecund collaboration should continue after our victory.

Yesterday we exchanged professors; to-morrow we shall exchange students. Thanks t o the zeal of my devoted collaborator, Engel, thanks to the friendly efforts of some among you, quite a number of American chemists have already subscribed their names for membership in the SocietC de Chimie Industrielle which recently has been founded in Paris, and I hope that at our return in France, we shall be able to reciprocate and t o increase the number of members of the American Chemical Society. In this way, the field shall have been well prepared for the exchange of ideas which will precede our common efforts. I n their own turn, other elements of intimate collaboration will present themselves t o reinforce all that exists already, and if I am enabled, within a few years, t o visit again your beautiful land, I have the firm conviction that I shall be able t o bring then the greetings of a newer France to a still greater America.
CURRENT INDUSTRIAL NEWS ESTIMATION OF TIN IN LOW-GRADE STUFF
STARCH SUBSTITUTES IN GERMANY
Mr. A. Adair contributes t o a recent issue of the South African Mining Journal a method of estimating tin in low-grade ores, tailings and slimes. The method is stated t o have been devised on account of the difficulty which the sodium peroxide and other fusion methods present, owing to the trouble experienced in separating the tin from the excessive amounts of gelatinous silica produced, for, in practice, evaporation with hydrochloric acid to render the silica insoluble results in large losses of tin as stannic chloride. The method described depends on converting the stannic oxide into its phosphide without fluxing the gangue. The metal is then dissolved and readily separated kom the nongelatinous silica. The ore is roasted or treated with nitric acid and washed free from pyrites. It is then ground to impalpability and mixed with 0.4its weight of dry ammonium phosphate and 0 . 2 charcoal, both ground finely and well mixed. For 5 g. ore take an annealing cup and grind a lid to it till i t closes all around. The inside is wetted and rubbed with a little black lead t o get a good coating for polishing when dry. A kerosene blast lamp and jacket are used, first heating gently for 2 0 min. and then a t a red heat for one-half hour, cooling off with the vapor of the lamp. Any charcoal remaining is blown off and the ignition transferred t o a porcelain crucibie and ground t o the finest powder. It is transferred to a flask and wetted with alcohol. 25 cc. of boiled hydrochloric acid are added and the mixture left in a warm place over night, by which time the tin is in solution and easily filtered from the gangue and charcoal. Results on a sample of ore containing I .5 per cent stannic oxide, from seven successive tests, gave a n average value of I , Z I per cent.-A. MCMILLAN.
In all countries, says the Oil and Color Trade Journal, 5 2 (1917). 985, articles which were quite common prior to the war have now had to be replaced by others, either because the importation of the necessary raw materials from foreign countries has ceased or because such raw materials are being employed for other purposes to better advantage. Some interesting data regarding starch substitutes have recently been published by Dr. R. Koenig, who has investigated several types. At the beginning of the war starch substitutes in Germany consisted chiefly of potato flour mixed with chalk ground as fine as possible. When potato flour was no longer available, admixtures of powdered gelatine, white glue and fine white chalk were used. The percentage of chalk increased very rapidly as gelatine advanced in price so that in one instance it was found that the percentage of chalk increased from 2 0 to 35 per cent in 14days. Although these products, as long as the glue was not of a yellowish color, were fairly satisfactory, still their price was generally out of all proportion to their actual value. Other preparations placed on the market consisted of crystallized bitter or “cat” salts, water and burnt magnesia. The latter was afterwards sold as “fatless” washing medium. This contained 70 per cent bitter salt, 23 per cent water and 7 0 per cent magnesia. The salt was dissolved in water and the magnesia thoroughly stirred in till dissolved, whereupon it was allowed to stand in moulds for some hours till it stiffened through the formation of oxysulfate.-M.
COCONUT INDUSTRY From a recent report it would appear that the coconut industry of Trinidad and Tobago, which has been affected by prolonged droughts in previous years, has now recovered. The export figures for 1916 show an increase of 3,000,000 nuts above the number exported in 1915. On the other hand, however, the export of copra has decreased by about I,OOO,OOOlbs., which works out a t about Z , ~ O O , O O O nuts, so that the real increase for 1916 is only 500,ooo nuts. The cultivation is being rapidly extended.

SALTPETER PRODUCTION IN INDIA From the bulletin issued by the Agricultural Institute, Pusa, it would appear that, subject to certain conditions being realized, there is a good opportunity for developing the production of saltpeter in India. The general conclusions arrived a t are as follows: (I) The present sources of saltpeter are not fully utilized on account of the drawbacks a t present associated with the nuniah’s business and the low price of crude saltpeter; ( 2 ) artificial niter-beds, on account of the favorable soil and climatic conditions in Bihar would probably form a useful added source of saltpeter; (3) the present methods do not allow of recovery of all the nitrate present in the earth worked. It is t o be determined whether a better method of extraction could be devised capable of being carried out and whether the efficiency of this method would necessarily depend upon some relaxation or revision of the restrictions a t present imposed by the Salt Department; (4) the present conditions of trade in this commodity require examination to determine whether a great demand for Indian saltpeter would result from organized efforts to improve them such as the elimination of the middleman and the standardization of the product itself.-M.
