Goutal. B.. calls attention to the adulteration of orange flower 
water by a distillate from the leaves and young shoots of Citrus 
big a r radio Risso. The author, failing in being able to distinguish 
the adulteration by chemical means, has studied various concentra- 
tions by the cryoscopic method and believes, that it will be possible 
to develop a satisfactory basis for determining the purity of orange 
flower water by this means. — Bull, de pbarm. du Sud-Est, 1905, v. 10, 
pp. 217-221. 
ARGENTI NITRAS. 
Baibakow. A. A., reports observations with 16 patients and believes 
that he is justified in concluding that the administration of silver 
nitrate tends to increase the motor activities of the stomach, lessen 
the content, and. in the majority of cases, at least, increase the total 
acid content. (From Russki Wratch. 1905. Xo. 31—33.) — Biochem. 
Centralbl.. 1905. v. 4. p. 122.

ARNICA. 
Klobb. T., contributes some further notes on the phytosterol of 
arnica flowers, designated by him as arnisterin. and points out that it 
contains two OH groups, and he therefore proposes the name £t arnid- 
iol," to indicate its closer relations to the alcohols. (From Bull, des 
sc. pharm., 1905, No. 9.) — Pharm. Ztg.. Berlin. 1905, v. 50, p. 846. 
Fernald. M. L.. discusses the occurrence of the genus Arnica in 
northeastern America. — Bull. Torrey Bot. Club. 1905, v. 32, p. 557. 
y Guindal. J. M., describes some adulterants and substitutes for 
arnica root. (From Rev. Sci. de Barcelona.) — Proc. Am. Pharm. 
Ass., 1905. v. 53, p. 635. 
La Wall, Chas. H., is reported as having fotmd two samples of 
tincture of arnica containing wood alcoh ol. — Ibid. . p. 183. 
Caldwell. Paul, suggests that in making tincture of arnica the drug 
be mixed with an equal weight of powdered pumice, moistened with 
sufficient of the menstruum, macerated for twenty-four hours, and 
finally exhausted by percolation in the usual way. — Drug., Circ. & 
Chem. Gaz.. X. Y., 1905. v. 49. p. 306. 
ARSENI IODEDUM. 
Cowley and Catford. in discussing the description for arsenic 
iodide, say : 
A pharmacopoeia should give " sufficient " tests for purity. Not merely refer- 
ence to methods of preparation but the best and most complete working formula 
should be given in detail. — Pharm. J.. Lond., 1905. v. 21, p. 131. See also p. 217.
