Gonnermann, M., reports a number of experiments on the action 
of enzymes and intestinal bacteria on glucosides and alkaloids. The 
substances reported on in this series of papers are sinigrin, arbutin, 
amygdalin, sapotoxin, atropine, cocaine, morphine, and oxydimor- 
phine. — Apoth. Ztg., Berl., 1906, v. 21, pp. 976-979, 988-989, 998-999.

6. VEGETABLE DRUGS. 
Bougault, J., in a review of the new U. S. P., notes that the descrip- 
tions of vegetable drugs are very brief and limited to morphologic 
and organoleptic characters; there are no histologic characters given 
and rarely any microscopical characters for the powders. The ab- 
sence of directions for the preparation of simple powdered drugs 
seems curious to the reviewer and he wonders if they are not used 
in this form. — J. de pharm. et de chim. Par., 1906, v. 23, pp. 285, 288. 
Busby, Henry H., discusses the identification and preservation of 
drugs, points out how certain general characteristics are utilized for 
identifying drugs, and how a knowledge of these same characteristics 
with some knowledge of the composition of the drug can be utilized 
for its preservation. — Proc. Am. Pharm. Ass., 1906, v. 54, pp. 
255-259. 
Holmes, E. M., discusses the preservation of drugs and points out 
that it is not light alone which destroys color in plants and alters 
their constituents, but oxidizing enzymes in the presence of moisture. 
He calls attention to the possible use of lime as an aid in the complete 
drying of drugs and asserts that samples of flowers and leaves that 
have been on exhibition in the Museum of the Pharmaceutical So- 
ciety for upward of twenty-five years, and in the drying of which 
lime was used, still retain their original color. — Pharm. J., Lond., 
1906, v. 22, p. 127. 
Weigel, G., points out that the Ph. Ndl. devotes considerable atten- 
tion to the specification of the time of year in which certain drugs 
are to be gathered. Then, too, certain drugs like digitalis, colchi-
