102 HISTORY OF PHYTOPATHOLOGY 



mental studies on the life histories of several pathogenes, 

 namely, Phytophthora infestans, Entyloma Ranunculi, 

 Puccinia graminis, and the Botrytis sp. of lily. (See 

 Lindau and Sydow, 1909, 2 : 723-725.) In 1895 he 

 was made professor of botany at the University of Cam- 

 bridge, where he remained until his death in 1906 at the 

 age of fifty- two. His years at Cambridge were full of 

 activities along many lines of botany, both research and 

 teaching, and were exceptionally fruitful. His chief 

 pathologic papers during the last eleven years of his 

 life were: Disease in plants, 1 and his numerous classic 

 studies from 1899 to 1905 on parasitism as exhibited in 

 the rusts and other fungi. 2 His studies in parasitism 

 may be said to have laid the foundation for all later
