AMMONII CHLORIDUM. 
Wiebelitz. H.. points out that the neutrality of ammonium chloride 
required by the Ph. Germ. IV is only applicable to a solution that 
has as yet not been decomposed by the water. — Pliarm. Zt g., Berl., 
1906, v. 51, p. 1003. 
Lefeldt, Max. asserts that the solution of ammonium chloride in 
water (1=20) always reddens blue litmus paper, and this should be 
permitted by the pharmacopoeia. — Ber. d. pharm. Gesellsch., Berl.. 
1906. v. 16. p. 332. 
Hankey, William T.. asserts that a good quality of ammonium 
chloride that is white and sightly, usually contains from 0.5 to 2 per 
cent of nonvolatile matter, consisting of sodium sulphate and chloride 
with traces of calcium and iron. The higher grade brings a very 
much increased price and he doubts whether the end sought will 
justify paying the difference. — Am. Druggist. X. Y., 1906. v. 19. 
p. 360. 
G. Hell & Co., in Troppau, point out that ammonium chloride is 
not infrequently contaminated with iron. Of six samples examined 
three were rejected because of their excess of- iron or because of 
empyreumatic contamination. — Pharm. Post. Wien, 1906. v. 39. p. 150. 
Patch. E. L., found ammonium chloride that was 65.33. 67.12. 
77.3, 92.67, 91.59, 98, and 98.7 per cent pure. — Proc. Am. Pharm. 
Ass., 1906, v. 51, p. 333. 
Caspari, Chas E., reports four samples examined: One U. S. P. ; 
three contained metallic impurities.— Proc. Missouri Pharm. Ass., 
1906. p. 100. 
Ohliger. Willard, reports ammonium chloridum containing iron 
sufficient to darken an ammoniacal liniment, normally . white, by 
reason of the ferric hydroxide. — Proc. Michigan Pharm. Ass.. 1906. 
p. 16. 
Chiron, Paul (L* Art Med.) , recommends ammonium mure in severe 
and long-continued sciatica, with pain in the left side, as if the 
tendons were too short : lame while walking and while sitting. — 
Abstr. Hahneman. Month., Phila.. 1906, v. 11. p. 796. 
AMMONII IODIDUM. 
Smith, F. A. Upshur, points out that ammonium iodide may be 
deprived of free iodine by adding to its concentrated aqueous solu- 
tion sufficient ammonium sulphide to render it colorless, then filtering 
and evaporating to dryness. — Pharm. J., Bond., 1906. v. 22. p. 32. 
AMMOUII SALICYLAS. 
Coblentz, Virgil, notes that ammonium salicylate is furnished either 
as a crystalline anhydrous salt or crvstalized with one-half molecule 
of water * * * the 98 per cent salt adopted by the U. S. P.
