Bretau, in criticising Guigues’s results, showed that, under the in- 
fluence of heat, the basic formiate loses all its formic acicl and is 
transformed into a hydrate of quinine. — Ibid., v. 24, p. 493. 
Lacroix, H., adds some further remarks on the same subject. — 
Ibid., v. 24, p. 377. 
QUININE SULPHAS. 
Dohme, A. R. L., points out that owing to objections made by man- 
ufacturers of quinine the Committee of Revision of the U. S. P. did 
not see its way clear to adopt the standard official in the Ph. Germ. 
IV. While the present U. S. P. standard is better than it was it is 
not what it should be, as it enables Germany to unload on the United 
States all quinine sulphate that will not meet the Ph. Germ. IV re- 
quirements. — Am. Druggist, N. Y., 1906, v. 49, p. 267. 
The Ph. Brit. Committee of Reference in Pharmacy report on 
quinine sulphate says the Ph. Brit, test should be replaced by that in 
the French Codex, which is more easily carried out. The Ph. Brit, 
standard requires a less pure quinine sulphate than any other impor- 
tant pharmacopoeia. The 3 per cent of cinchonidine obtained in the 
assay indicates the presence of more than twice the amount in the 
sample. — Chem. & Drug., Loncl., 1906, v. 69, p. 864. 
Biginelli. P., points out a cause of error in the determination of 
quinine in quinine sulphate and discusses the influence of various fac- 
tors on the final results. — Boll. chim. farm., Milan, 1906, v. 45, pp. 
253-260, 372-375, 489M93, 604-606, 708-711. 
Dunlop, Thomas, notes that quinine sulphate with phenazone re- 
mains insoluble, but on the addition of citric acid a perfect and per- 
manent solution is produced. — Pharm. J., Lond., 1906, v. 23, p. 144. 
Gane, E. H., reports finding four samples of quinine sulphate 
which did not pass the U. S. P. ammonia test. — Proc. Am. Pharm. 
Ass., 1906, v. 54, p. 344. 
Sayre, L. E., reports that three out of five samples examined con- 
tained a slight excess of other cinchona alkaloids. — Bull. Kansas Bd. 
Health, 1906, v. 2, p. 175. 
RESINA. 
Herty, Chas. H., discusses the composition of rosin and reviews 
some of the literature relating to it. — Chem. Eng., Phila., 1906-7, 
v. 5, pp. 235, 236. 
An editorial discusses the economic conditions prevailing and pre- 
sents a table giving high and low quotation^ for each month during 
1904, 1905, and 1906. — Oil, Paint, and Drug. Rep., 1906, v. 70, Dec. 
3, p. 7. 
RESINA PODOPHYLLI. 
The Ph. Brit. Committee of Reference in Pharmacy report on 
resin of podophyllum says the question of the exclusion of Indian
