Puckner, W. A., calls attention to the dearth in the English lan- 
guage of a systematic discussion of the many new remedies and de- 
votes the article to a discussion of the chemistry of the organic silver 
compounds. — J. Am. M. Ass., 1906, v. 47, pp. 1*258-1261. 
Wilbert, M. I., presents a formula and outlines the method for pre- 
paring a mixture containing nascent iodide of silver.— Am. J. Pharrn., 
1906, v. 78, pp. 64-68. 
Derby, G. S. (Boston M. and Surg. J., Sept. 29), compared the 
bactericidal properties of various silver preparations using the 
Staphylococcus pyogenes aureus . The results are given in the ab- 
stract. — J. Am. M. Ass., 1906, v. 47, p. 1226. 
A contributor to the “ Pharmacology ” column quotes Myles Stand- 
ish (Optha. Eec., August, 1906) to the effect that negative laboratory 
tests form a poor foundation for clinical advance. Referring to the 
experiments of Derby he thinks that clinical experience shows that 
the silver preparations have a greater bactericidal action than the 
laboratory tests would indicate. Standish concludes that the modern 
silver preparations are effective in gonorrhoeal infections of the con- 
junctiva. — Ibid. : v. 47, p. 1393. 
ARNICA. 
Hartwich, C., showed a sample of arnica adulterated with flowers 
of Taraxacum officinale. — Schweiz. Wchnschr. f. Chem. u. Pharm., 
1906, v. 44, p. 8. 
Klobb, T., reports some experimental work on the chemistry of 
arnidiol, a phytosterin obtained from Arnica montana. (Bull. Soc. 
chim., Paris, 1906, v. 25, pp. 741-744). — Biochem. Centralbl., Leipz., 
1906-7, v. 5, p. 907. 
The Ph. Brit. Committee of Reference in Pharmacy believe that 
arnica rhizome should have an ash figure. — Chem. and Drug., Loud., 
1906, v. 69, p. 863. 
Barnard, H. E., reports that 9 of 81 samples of tincture of arnica 
examined were found to contain methyl alcohol. — Rep. Indiana Bd. 
Health, 1906, p. 384. 
Chiron, Paul, (L’Art Med.) recommends arnica after any kind of 
effort or exertion, burning, stinging, tearing pains ; numb and bruised 
feeling in the affected limb. Constant change of position, as every- 
thing on which the limbs lie feels too hard. It is especially useful in 
women during confinement. — Abstr. Hahneman. Month., Phila., 1906, 
v. 41, p. 796. 
ARSENI IODIDUM. 
Coblentz, Virgil, commenting upon the impurity of the commercial 
article, says that the limits of 83 per cent [U. S. P. VIII. 82.7 per 
cent] of iodine and 16 per cent [U. S. P. VIII, 16.3 per cent] of 
arsenic, corresponding to a 99 per cent salt, are fair for all manu-
