expect to meet with gross imposition if he ventures to 

 purchase the crude drug under any of these titles, or by 

 the common name, "Jaborandi." Nor is this necessa- 

 rily due to intent of either importer or jobber, for in 

 general each dealer in this foreign drug is helpless in 

 the face of conditions that lie entirely beyond his con- 

 trol, such as collectors at a distance. In our opinion, 

 the best American authority on "Jaborandi" problems 

 from the botanical side, is Professor H. H. Rusby, 

 M. D., of the Columbia University, New York. His 

 paper on "The Pilocarpus Leaves of Commerce," pre- 

 sented to the American Pharmaceutical Association in 

 1903, and republished in the Bulletin of Pharmacy, 

 October, 1903, is invaluable. We have consulted this/ 

 freely in our study of pilocarpus. Mr. E. M. Holmes, 

 the best European authority, (see also Index Kewensis), 

 states 1 that the following species and varieties were 

 known under the name of Jaborandi as early as 1895. 

 Since that date, two other species have been added 

 (Rusby).
