1606. RusBY, H. H. The H, K. Mulford Biological Expedition. Druggists Circ. 64: 

 425-426. 1920. — A biological expedition, sponsored by the H. K. Mulford Co., in charge of 

 Dr. Rusby will visit the upper Amazon valley, reaching southeastern Colombia and north- 

 western Brazil. The object is to investigate the medicinal plants of the region, but a study of 

 the insects and reptiles abounding in the region will be undertaken by specialists and the 

 fishes of the Amazon will receive especial attention. It is expected that the expedition will 

 be isolated from civilization for about 6 months. — C. M. Sterling. 



1G07. Schneider, Albert. Pharmaceutical research. Druggists Circ. 65: 163-165. 

 1921. — The author discusses research and its necessity in pharmacy. A plan for the develop- 

 ment of research in pharmacy and related subjects is presented. — C. M. Sterling. 



1608. Seel, E. Beitrage zur Kenntnis der Chemie und Pharmakologie der Aloe. [Chemis- 

 try and pharmacology of aloes.] Arch, der Pharm. 257: 212-259. 1919. — The important con- 

 stituents of aloes are given as: (1) Water-soluble crystalline aloin; (2) water-soluble amor- 

 phous aloetin; (3) resinous portion (insoluble in cold water); and (4) emodin (methyltrioxy- 

 anthraquinone or oxymethyldioxyanthraquinone). Detailed chemical analyses are given. 

 0.5-2.0 gr. of the puraloins (oxidation products of aloin) were found to give a mild purgative 

 effect in children and dogs, but this was not dependable. The reliability of emodin as a cathar- 

 tic in doses of 0.2-0.4 gr. at 3-hour intervals is confirmed. Oxyemodin is somewhat weaker, 

 0.5 gr. often being required. Like emodin it can be injected hypodermically. The only 

 important effect of oxidizing aloe constituents with sodium peroxide appears to have been the 

 purification of emodin itself. — H. G. Barbour. 



1609. Stockberger, W. W. Commercial drug growing in the United States in 1918. 

 Amer. Druggist and Pharm. Rec. 68^: 17-18. 1920. — Recent work to obtain marketable quan- 

 tities of Belladonna, Cannabis, Digitalis, Calendula, sage, and henbane is reviewed. — C. M. 



Sterling. 



1610. Stockberger, W. W. Crude drug situation in the United States. Western Druggist 

 43 : 21-24. 1921. — The author reviews the crude drug supplies in the U. S. A. at the close of the 

 World War. By way of improvement he suggests cultivation of plants in medicinal gardens, 

 and the cooperation of state schools of pharmacy, botanists, high school teachers, and county 

 agents in compiling information concerning the drug resources of the states. — C. M. Sterling. 



1611. Sw ANSON, C. O. Hydrocyanic acid in Sudan grass and its effect on cattle. Jour. 

 Amer. Soc. Agron. 13: 33-36. 1921. — Sudan grass giving a strong test for HCN was not harm- 

 ful to cattle. Liberation of HCN from Sudan grass is apparently associated with enzj'me 

 action. Slow drying causes HCN to disappear. The amount of HCN obtained was not 

 diminished when Sudan grass was made into silage. Frosted Sudan grass, when tested im- 

 mediately, gave very large amounts of HCN which rapidly disappeared when the plant wilted.

1612. Wallace, Emma Gary. Some facts concerning camphor farming. Pharm. Era 

 53: 261-262. 1 fig. 1920. — An account of recent i)lans to furnish native-grown camphor for 

 the American market is given. — C. M. Sterling. 



1613. Watermeyer, F. W. American liquid styrax. Amer. Druggist and Pharm. Rec. 

 68^: 20. 1920. — American stj'rax, obtained from Liquidambar styraciflua, has been collected 

 from large forests of trees located in Honduras. The species occurs in the southern states also, 

 but in relatively small quantities. For many purposes the American styrax is superior to
