coloration and precipitation of a solution of morphine hydrochloride ; 
(2) the precipitation of strychnine nitrate; and (3) the precipitation 
and subsequent coloration of solutions of mercuric chloride. — Abstr. 
J. Am. Chem. Soc., 1905, v. 27, p. 1351. 
van Rijn (Pharm. Weekbl. v. 41, p. 1025) recommends cleaning 
the vessels with hydrochloric acid and water, then filling with dis- 
tilled water containing phenolpthalein. There must be no redden- 
ing after fourteen days. — Ibid., p. 1351. 
Wetterstroem, Theo. D., points out that a portion of the loss of 
acidity and even an impairment of the esters in brandies and whis- 
kies is to be attributed to the alkalinity found in white glass of 
reputed purity. — Drug. Circ. & Chem. Gaz., A. Y., v. 49, p. 312. 
17. TESTS. 
ACID, OXALIC. 
Moissan (Pharm. J., No. 3477, p. 845) shows that in the reaction 
between carbon dioxide and potassium hydride, at a temperature 
between 100° and 200° C., a quantity of oxalate is formed as well as 
formate. — Abstr. Merck’s Rep., N. Y., 1905, v. 14, p. 249. 
Baxter and Zanetti (Am. Chem. J., N. Y., v. 33, p. 500) outline a 
method for estimating oxalic acid in the presence of hydrochloric 
acid. — Abstr. Pharm. Ztg., Berlin, 1905, v. 50, p. 603. 
Patch, Edgar L., in report of committee on drug market, points 
out that oxalic acid frequently contains traces of nitric and sul- 
phuric acids and of iron. — Proc. Am. Pharm. Ass., 1905, v. 53, p. 182. 
ALKALINE MONOCARBONATES AND BICARBONATES. 
Cowley and Catford discuss the determination of alkaline mono- 
carbonates and bicarbonates and point out that the use of barium 
chloride is liable to yield erroneous results unless attention is paid 
to the proportion of barium chloride used. — Pharm. J., Lond., 1905, 
v. 21, p. 864. 
ALCOHOL, AMYL. 
Lyons, A. B., suggests that not the least important requirement 
would be “ it should leave no residue on evaporation.” — Proc. Am. 
Pharm. Ass., 1905, v. 53, p. 262. 
Beckmann, E. (Ztschr. f. LYiters. d. Nahrungsm., 1905, 1 & 2), 
outlines a method for the estimation of alcohol in alcoholic liquids, 
depending on the use of carbon tetrachloride as a solvent for the 
amyl alcohol. — Pharm. Ztg., Berlin, 1905, v. 50, p. 685. 
Gadamer, J., reports observations on the action of amyl alcohol 
on chlorethylalcoholate, that were made to determine whether the 
latter could be made to exchange the ethyl group for the amyl 
group. — Arch. d. Phar, 1905, v. 245, p. 30 ff.
