Battandier, J. B., discusses the color reactions for quinine and 
quinidine.— Year Book of Pharmacy, Lond., 1905, p. 136 (from J. 
Pharm. Chim.). 
Robertson, P. W., outlines a method for the estimation of quinine 
and cinchona alkaloids depending on the use of ammonium sulpho- 
syanide and a zinc or mercury salt. — Australas. J. Pharm., 1905, v. 
20, pp. 101-102. 
Guiges, P., presents a study of the action of ammonia and its 
salts on the crystallization of the salts of quinine. — J. de Pharm. et 
de Chim., Paris, 1905, v. 22, p. 299. 
Yvon produces a tasteless quinine mixture by mixing a small quan- 
tity of sodium bicarbonate with quinine, and sufficient oil of almonds 
to form a paste. The resulting mixture may be flavored by adding 
a trace of oil of lemon, or oil of peppermint. The sodium bicarbonate 
is said to neutralize the acids present in the mouth and thus prevent 
solution. — Pharm. Ztg., Berlin, 1905, v. 50, p. 663. 
Lacroix, H., gives a method for preparing and some description of 
the properties of quinine formiate. — J. de Pharm. et de Chim., 1905, 
v. 22, p. 99. 
Allen reports finding quinine capsules that were not true to the 
claims made for them. — Proc. Michigan Pharm. Ass., 1905, p. 80. 
Ramsay, E. T., discusses the use of quinine in pneumonia. — Abstr. 
in J. Am. M. Ass., 1905, v. 45, p. 1447 (from Virginia M. Semi- 
Month.). 
Nieder, Charles F., reports his observations in connection with 
several cases of pneumonia treated with quinine and iron. — J. Am. 
M. Ass., 1905, v. 45, p. 1572. 
QUININJE BISULPHAS. 
Gane, E. H., reports finding a sample of quinine bisulphate contain- 
ing 1.7 per cent of potassium sulphate. — Proc. Am. Pharm. Ass., 
1905, v. 53, p. 188. 
QUININE HYDROCHLORIDUM. 
Carette, M. H., discusses the composition of neutral hydrochloride 
of quinine and the variation in composition when crystallized from 
different solvents. — J. de Pharm. et de Chim., Paris, 1905, v. 22, 
p. 299. 
Erba, Carlo, calls attention to his study of the composition of 
neutral hydrochloride of quinine (Boll. Farm., 1901). According to 
his observations the salt crystallized from 95 per cent alcohol is 
hydrated and has the formula C 20 H 24 O 2 N 2 HCl,C 6 H 6 OH 2 O, whilst 
Carette states that it contained 1.5 molecules of water. — J. Chem. 
Soc., Lond., 1905, part 2, p. 151 (from J. Pharm. Chim.).
