1684. Kilmer, F. B. The study of drugs. Amer. Jour. Pharm. 91: 139-147. 1919. — 

 The author briefly reviews the present knowledge of several of our more common drugs as 

 belladonna, aconite, aloes, etc., pointing out the fact that very little is really known about 

 them at the present time. "As pharmacists we are most interested in its active principle. 

 What is the active principle of belladonna? The usual answer is "atropine." Is this the cor- 

 rect answer? Investigation has shown that atropine does not exist in cultivated belladonna, 

 nor indeed in belladonna when carefully handled and dried. Atropine is a product, or a 

 derivative, produced during the manipulation of the drug." — Anton Hogstad, Jr.

 of crude drugs, is touched upon, as well as the experimental work carried out by federal and 

 state governments in their endeavor to help make it a profitable enterprise. Detailed methods 

 are given for the proper handling and cultivation of belladonna, hyoscyamus, digitalis, can- 

 nabis, and stramonium. — Oliver A. Farwell.

 paying crop may generally be obtained even in localities not exceptionally favorable for its 

 growth. The paper includes a study of germination, planting, effect of fertilization, effect 

 of certain inorganic salts upon the growth and active constituents, effect of drying at differ- 

 ent temperatures upon the activity. With summary and bibliography. — Anton Hogstad, Jr.
