b\' all who had dealings with him. Jionors came to him 

 abundantly ; he was President of both the American and the 

 l^ritish Association, as well as of the Geological Society of 

 America, and the Royal Society of Canada. 



Feeble health came to him in 1892, and soon necessitated 

 the relinquishment of his university duties. Strength never re- 

 turned to him ; but he failed gradually until on November 19, 

 1899 he passed away, leaving an untarnished name, and a 

 record which is one of the brightest. His memory will be 

 cherished as that of a conscientious man, and an unselfish 



worker in science. ♦ t t o

 tion of the talc had been attributed to the magnesian limestone 

 or intrusion of a magnesian silicate rock. Professor Peck re- 

 plied that he considered the tremolite rock to be due to the al- 

 teration of a siliceous dolomite ; the talc, possibly to the inter- 

 change of silica from the Pre-Cambrian gneisses, and magnesia 

 from the adjacent dolomite limestone. The serpentine and 

 ** viridolite " had indeed been subjected to much shearing and 

 fracture, but had been solidly recemented, so that they could 

 be quarried out in large blocks, free from cracks, sometimes of 

 twenty tons weight, in the case of the " viridolite."

 F. E. Lloyd remarked that the cells of algci^, to whose accumu-
