work at Cambridire. He entered on his duties with enthusiasm, but the 

 willing soul found scaut support from the enfeebled body. After his 

 first course of lectures, he strove to find new health in a journey with 

 his students in Iowa ; but this resource failed him, and he returned to 

 Cambridge with mortal illness upon him, and died on the morning of 

 October 3, 1872. 



Professor Perry well represented a class of workers, unfortunately 

 few in this country, who combine the duties of pastoral teaching with 

 the prosecution of scientific researches. Had his life been prolonged, 

 he would undoubtedly have achieved a first place among those who 

 have sought to reconcile the teachings of Christianity with the record of 

 the great stone book. In his few published papers, this effort to recon- 

 cile our newly acquired knowledge with the doctrines which form the 

 essential basis of our civilization plays a large part. Here, as well as 

 in his more purely scientific writings, his great modesty, leading him 

 genei-ally to anonymous publications, makes it well-nigh impossible for 

 the writer of this memoir to prepare a catalogue of his papers. His 

 geological publications were mainly limited to the rocks of New Eng- 

 land ; but in his lectures, which were not prepared for publication, he 

 propounded certain general views of origLnality and importance. Most 

 deserving of memory among these was his theory of the origin of the 

 mica schists and other foliated rocks. These he considered to have 

 been formed by the precipitation of their components from the atmos- 

 phere, immediately after the cooling of the primeval crust to the point 

 of solidification. While the writer is not prepared to accept this vijew, 

 he must bear testimony to the ability with which Professor Perry 

 advocated it.
