Charteris, Frank, discusses the action of ammonium bromide and 
concludes that it is more toxic than sodium bromide. With large 
doses the predominating action is that of ammonium. The elfect 
on the isolated frog's heart is not marked. With repeated non-toxic 
doses a bromide action may be produced. — Therap. Gaz., Detroit, 
1905, v. 29, pp. 722-726. 
AMMONII CARBONAS. 
Patch, Edgar L., found traces of chloride and sulphate in samples 
of ammonium carbonate. — Proc. Am. Pharm. Ass., 1905, v. 53, p. 182. 
AMMONII CHLORIDUM. 
Patch, Edgar L., is reported as having found ammonium chloride 
containing traces of aluminum and of copper. — Proc. Am. Pharm. 
Ass., 1905, v. 53, p. 182. 
An abstract from the monthly circular of Roessler and Hasslacher 
mentions a sample of ammonium chloride consisting of ammonium 
chloride, 49.97. per cent; sodium chloride, 44.6 per cent; sodium sul- 
phate, 3.52 per cent ; calcium sulphate. 1.55 per cent, and iron oxide, 
0.09 per cent, the remaining portion being estimated as moisture. — 
Drug Topics, 1905, v. 20, p. 290. 
Bauer, H. (Pharm. Ztg., 1905), points out that because of the 
ready hydrolysis of ammonium chloride and of ammonium bromide 
in aqueous solutions, with the liberation of a corresponding amount 
of acid, the requirement of the Ph. Germ., IV, that solutions of these 
salts be neutral to litmus paper is not justified. — Pharm. Prax., 1905, 
v. 4, p. 172. 
Jean (Ann. Chim. anal, appl., v. 9, p. 257) proposes a rapid titra- 
tion for ammonium chloride and ammonium sulphate. — J. Am. Chem. 
Soc., 1905, v. 27, p. 1348. 
Rupp and Roszler report on some experiments made to determine 
the availability of hypobromite solutions for the estimation of am- 
monia and of ammonium salts. It was found that free ammonia 
increases the alkalinity of the hypobromite solution and is not 
directly applicable— Arch. d. Pharm. Berlin. 1905, v. 243, p. 104. 
AMMONII SALICYLAS. 
Schimpf, Henry W., asserts that ammonium salicylate is so little 
used that its introduction into the U. S. P., VIII. seems unneces- 
sary. — Am. J. Pharm.. Phila., 1905, v. 77, p. 514. 
AMYLIS NITRIS. 
Francis, John M., joints out that a considerable portion of the amyl 
nitrite on the market is of an inferior grade, and some of it, from
