POPULAR SCIENCE REVIEW. 
1 Spee-gear, bottle in case,’ whatever that may be ; while the term 1 panti- 
graph’ is still retained in the introduction. The blunders appear to be 
impartially distributed over the various sub-sections ; while we have 1 wol- 
fram phosphide,’ ‘ siliconcalcium,’ and 1 molibdate of lead,’ on the one hand, 
we meet with 1 Kemala ’ and ‘ Saborandi ’ on the other ; and among the 
rocks and minerals, 1 Trooshte ’ for troostite, 1 dimyte,’ repeated, for dunite, 
1 Garnet fils,’ ‘ Hosed felsyte,’ 1 Hokscharowite,’ &c. Finally, we will confine 
ourselves to directing attention to about a dozen of the errors in the names 
of persons which we have met with during a superficial examination of this 
revised edition of the Catalogue : — ‘ Andrew ’ for Andrews, 1 Berzelius/ 
‘Bilstein ’ for Beilstein, 1 Cloes ’ for Cloez, ‘ Sir Humphery Davy,’ 1 Eisen- 
rohr ’ for Eisenlohr, ‘ Erltenmeyer ’ for Erlenmeyer , 1 Fritzshe,’ 1 Kakuli ’ for 
Kekule , 1 Butlerow/ 1 Budnen ’ for Budneff, ‘ Schick ’ for Schiek, 1 Siemgan’ 
for Siemens, ‘ Smith ’ for Smithson, and 1 Wrohlesky ’ for Wroblevsky.” 
Nitrogen and Albumen in the Milk of Women and Coios. — Dr. Leo 
Liebermann states in Liebig’s Annalen (Bd. 181, Heft. 1), that both in 
Brunner’s and in Hoppe-Seyler’s method a considerable part of the albumi- 
noids escapes precipitation. Haidler’s method, on the other hand, gives the 
total amount of the lacteal albuminoids, which may also be entirely thrown 
down by means of tannin. In addition to casein and albumen a third and 
distinct albuminoid body is present, but there is no nitrogenous body found 
in milk except such as belong to the albuminoid class. 
American Chemical Society. — The “ Chemical News ” of July 14 says that 
at a meeting of American chemists, held lately at the New York College of 
Pharmacy, it was resolved to form a society to be called “ The American 
Chemical Society,” and at a subsequent meeting the following officers and 
committees were appointed : — President — John W. Draper. Vice- Residents 
— J. Lawrence Smith, Frederick A. Genth, E. Hilgard, J. W. Mallet, 
Charles F. Chandler, Henry Morton. Corresponding Secretary — George F. 
Barker. Recording Secretary — Isidor Walz. Treasurer — W. M. Habir- 
shaw. Librarian — P. Casamajor. Curators — Edward Sherer, W. H. 
Nichols, Frederick Hoffmann. Committees on Papers and Publications — 
Albert B. Leeds, Herrmann Endemann, Elwyn Waller. Committee on Nomi- 
nations — E. P. Eastwick, M. Alsberg, S. St. John, Chas. Frobel, Chas. M. 
Stillwell. 
The Action of certain Filters has been gone into by Mr. Alfred Wanklyn, 
who reports as follows in the “Chemical News” (July 14) on the action of 
the “ Silicated Carbon Filters,” which, as we have already reported in a 
former number of this journal, are unquestionably the best species of filter. 
A solution of hydrochlorate of morphia in common London water was pre- 
pared by taking P320 grms. of hydrochlorate of morphia, dissolving it in 
water, and diluting the solution to 10 litres. In this manner a solution 
containing 0T32 grm. of the hydrochlorate per litre of water was obtained. 
Submitted to the ammonia process, this solution was found to yield 2-60 
m.grms. of albuminoid ammonia per litre. Five litres of this solution were 
then allowed to run through the same silicated carbon filter which had been 
employed for the experiments on quinine, described before, and the 5 litres 
of filtrate were then thrown away. In this manner the most simple dis- 
placement of the liquid occupying the pores of the filter was ensured.
