Theodore Greely White died at -his residence in Xew Yoriv 
city on July 7th, in the twenty-ninth year of Iiis age. His 
death was sudden and unexpected, and will be much regretted 
by all geologists who were acquainted with him and his work.

early education in New York city, and even while still a school- 
boy showed the deepest interest in natural science and through 
his contagious enthusiasm interested many others of his age

school of mines in 1890, and during his college vacations de- 
voted much of his time to botanical work, making a detailed 
study of the flora of Alt. Desert, Me. He received the degree 
of Ph. B. from Columbia in 1894, his graduation thesis being 
"The Geology of W^illsboro and Essex townships," N. Y. Thfs 
piece of work was really the beginning of a far larger investi- 
gation, which he took up for Iiis doctorate, viz. the study of the 
Ordovician in the Lake Champlain valley.

Columbia as a post-graduate student in geology, taking his M. 
A. degree in 1895 ^^^ ^''is Ph.D. in 1898. In 1895 ^"<^1 ^896 he
