THE BOTANISTS OF PHILADELPHIA. 23 



H. C. Porter and J. W. Harshberger. A list of the active 

 members of the society is given in an appendix. 



The Philadelphia College of Pharmacy has also been 

 an influential botanical centre. Several excellent botanists 

 have occupied the chair of materia medica and botany, as 

 John M. Maisch, Edson S. Bastin, Henry Kraemer and 

 Clement B. Lowe. The chemical and pharmaceutical side 

 of botany have been much emphasized, and much meri- 

 torious work has been done, both by the chemists and 

 botanists of the institution. The American Journal of 

 Pharmacy is a valuable epitome of the work accomplished. 



The late Professors Trimble and Bastin, of the faculty, 

 were actively engaged in botanical research, the former on 

 the tannins of plants, the latter on the coniferae and the 

 resins. From the College of Pharmacy many students have 

 received an inspiration for botanical study. The Herbarium 

 of the Philadelphia College of Pharmacy possesses the col- 

 lections of Elias Durand, Daniel B. Smith, Prof. John M. 

 Maisch, and that of Isaac Martindale, purchased by Messrs. 

 Smith, Kline, French and Company from the estate, as also 

 numerous contributions from botanical friends and students. 

 With a laboratory equipped for botanical and microscopical 

 study, and with such an excellent herbarium for comparison, 

 the College is enabled to give an extended course in botany. 



The Academy of Natural Sciences of Philadelphia was 

 founded March 21, 1812, by a few citizens "interested in 

 the study of the works and law^s of the Creator." From the 

 outset, the Department of Botany received a due share of 

 attention, and the first contribution to the Academy's Her- 

 barium * consisted of a collection of plants made in the 



* Torrey Bulletin VIII : 42, J. H. Redfield.
