Boudet describes a modification of the method of F. Jean for the 
estimation of tannin; applicable also for gallic acid. — Bull. Soc. de 
chiin., Par., 1906, v. 35, pp. 760-762. 
Philipp Koder, Wien, discusses the recent literature relating to the 
valuation and testing of tannin, and points out that much of the 
criticism of Gluckmann’s formaldehyde method of testing tannin is 
based on insufficient data, and that it is essential in all cases to deter- 
mine the composition of the material qualitatively. — Pharm. Post, 
1906, v. 39, pp. 216. 
G. Hell & Co., in Troppau, point out that tannin is frequently of 
poor quality; of 12 samples examined 6 did not comply with the re- 
quirements for a medicinally pure article. — Ibid., v. 39, p. 150. 
Caspari, Chas. E., reports one sample examined; contained much 
insoluble matter. — Proc. Missouri Pharm. Ass., 1906, p. 100. 
Kebler, Lyman F., reports that samples of tannic acid were, with 
one exception, extremely poor in quality. In nearly all cases a con- 
siderable amount was insoluble in water. — Proc. Am. Pharm. Ass., 
1906, v. 51, p. 318. 
Dixon, TV. E. (Lancet, Lond., Mar. 21, 1906), thinks that the tan- 
nins are worse than useless in internal haemorrhage.— J. Am. M. Ass., 
1906, v. 16, p. 1212. 
An editorial calls attention to W. E. Dixon's work (Lancet, Mar. 
21, 1906, p. 826) showing the uselessness of adrenalin, ergot, and 
astringents in general taken internally to control haemorrhage. — Ibid., 
v. 17, p. 11. 
ACIDUM TARTARICUM. 
Charles, P., proposes a modification of the method of Goldemberg 
and Geromon for the industrial determination ( u Dosage ") of tar- 
taric acid. — Bui. Soc. de chim.. Par., 1906, v. 35, pp. 171-171. 
An additional note. — Ibid., pp. 571-575. 
See also Chem. Xews, Lond., 1906, v. 93, pp. 107-108 : Ann. de 
chim. analyt., Par., 1906, v. 11, pp. 58-62. 
Tocher, J. F., gives a table for the separation of tartrates, citrates, 
and malates. — Pharm. J., Lond., 1906, v. 23, p. 87. 
Sullivan and Crampton conclude, from a large number of experi- 
ments with their test, that it is a convenient and reliable method for 
detecting tartaric acid in wines, ciders, fruit syrups, etc., and it is 
believed to be possible to adapt it to other substances as occasion may 
arise. — Am. Chem. J., 1906, v. 36, pp. 119—126. 
Kahn, Joseph I., discusses the detection of tartaric acid in the 
presence of citric acid. — Proc. Xew York Pharm. Ass., 1906. p. 205. 
Patch, E. L.. points out that in the test for sulphuric acid in tar- 
taric acid the strength of the solution, ten times that given for citric 
acid, is stated, but the amount of barium chloride and the time limit 
are omitted. — Proc. Am. Pharm. Ass., 1906, v. 51, p. 333.
