1906, v. 20, p. 185. 
Gehe & Co. discuss some of the peculiar conditions prevailing in 
the market for quinine, give a table showing the amount of bark, and 
the approximate quinine content of the bark offered in Amsterdam, 
also a table showing the decrease of export of quinine from Ger- 
many. — Handels-Ber., Gehe & Co., 1906, pp. 67, 68. 
A report on the drug market presents a number of interesting facts 
relating to the economic conditions prevailing in the cinchona and 
quinine markets. — Oil, Paint and Drug Reporter, 1906, Jan. 29, v. 
69, part 2, p. 33. 
An editorial discusses the price of quinine and states that the con- 
sumption of quinine has greatly decreased in 1905, probably owing 
to the w T ar on mosquitoes, but Java exported the largest amount of 
cinchona bark on record. — Brit. M. J., Lond., 1906, v. 1, p. 1370. 
Gordin, H. M., reviews the progress made in the chemistry of qui- 
nine during the year 1905. — Pharm. Rev., Milwaukee, 1906, v. 24, 
pp. 370, 371. 
Legradi, Th., discusses the chemistry and the probable constitution 
of quinine and cinchonine. — Ztschr. d. allg. oesterr. Apoth.-Ver., 
Wien, 1906, v. 44, pp. 187-188, 203-204, 215-217. 
Herder, M., discusses the use of calcium and barium-mercuric 
iodides as microchemical reagents for quinine. — Arch. d. Pharm., 
Berl., 1906, v. 244, p. 120. 
Deniges, G., discusses the influence of halogen salts on the fluo- 
resence of quinine sulphate solutions and presents the results of some 
experimental work to determine the amount of halogen salts neces- 
sary to cause the disappearance of fluorescence. — Bull. Soc. de 
pharm. de Bordeaux, 1906, v. 46, pp. 129-133. 
Ftihrer, Hermann, discusses the application of the thalleioquin 
reaction to quinine and its relation to bodies derived from p-oxychin- 
olin. — Arch. d. Pharm., Berl., 1906, v. 244, pp. 602-622. 
Patch, E. L., points out that the quinine called for by the U. S. P. 
is the trihydrated alkaloid. Market salts may contain 12 to 22 per 
cent excess of water, and the pharmacist should estimate the value of 
his purchase. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 329. 
Blome, W. H., found a sample which contained more cinchonine 
and cinchonidine than is permitted by the pharmacopoeia. — Proc. 
Michigan Pharm. Ass., 1906, p. 104. 
Evans, John, outlines a process for the determination of quinine 
in the wine, which he says should contain 10 to 12 per cent of alcohol 
and be free from preservatives. Several cases have been recorded in 
which alcohol was absent and salicylic acid present. — Apothecary, 
Boston, 1906, v. 18, p. 908.
