and physics, for although he became ultimately a 

 physicist, it was his original intention to be a chemist. 



Returning to America, he became Professor pro 

 tempore of Chemistry and Physics in the University of 

 Vermont, holding this chair during the college year 

 1866-7. 



In 1868-9 he was Acting Professor of Physics 

 in Columbia College, and was then appointed Pro- 

 fessor of Physics and the Mechanical Arts at the 

 newly-opened Cornell University. 



From 1870 to 1895 he was Hazard Professor of 

 Physics in Brown University. 



Professor Blake received the degree of A. M. from 

 the University of Vermont, and that of LL.D. from 

 Brown University. 



Owing to ill-health in his family, he resigned his 

 chair in the spring of 1895. His own fatal illness, 

 however, began even before this time, his constitution 

 having been overtaxed by the continuous and confining 

 duties of his profession. His death occurred at Hamp- 

 ton, Connecticut, October first, 1895.
