 Audubon, Say, Wilson, and others. His early education, 

 until he was fifteen or sixteen years of age, was spent at

 High School at Norristown, where he finished his scholastic 

 career. Even then his interest in botany showed itself. 

 He graduated in 1884 from the Philadelphia College of 

 Pharmacy, where he attended the lectures and studied

 especially within a radius of sixty miles of the city. As
