 1768 to the chair of botan^^ in the University of Pennsyl- 

 vania. He had the advantage of studying under tlie illus- 

 trious Swede, and was said to have been a favorite pupil 

 (Linna^o ex discipulis acceptissimus). John Bartrani

 of the year 1785, Humphrey Marshall published his Arbus- 

 tum Americanum,* a description of the trees and shrubs 

 native of the United States. It is the first strictly Ameri- 

 can botanical work. In 1791 William Bartram's Travels t

 America." Two years later, in 1803, the first elementary 

 work on botany by Prof B. S. Barton, § was published in 

 Philadelphia.

 of the Forest Trees of North America (Histoire des Arbres
