THE INCORPORATORS 1 59 



fessor of Natural History in Swarthmore College, in Swarth- 

 more, Pennsylvania. 



In 1 88 1 he was chosen President of the Academy of Natural 

 Sciences of Philadelphia; in 1884, Director of the Biological 

 Department of the University of Pennsylvania; and in 1886, 

 President of the Wagner Free Institute. Among the honors 

 he received at this period should be mentioned the Walker 

 Prize (which was doubled in special recognition of his services) , 

 the prize of the Royal Microscopical Society, the Lyell Medal 

 of the Royal Geological Society, and the Cuvier Medal of the 

 Academy of Sciences of Paris. 



" The bare enumeration of his published works, extensive in 

 length and in variety though it be, would give those who had 

 never seen this great naturalist no idea of the man or of the 

 source of this combination of versatility and accuracy which 

 rendered almost every observation he made directly or indi- 

 rectly an addition to science. In all that pertained to the acquisi- 

 tion of facts and to coordinating them afterwards he made of 

 himself a perfect machine in so far as he was insensible to and 

 unaffected by the ordinary passions of ambition or rivalry which 

 influence even the best scientists. He had a marvelous eye for 

 noting the minutest phenomena and appreciating the most 

 insensible dilTerences; he had an unusually retentive memory for 

 recording and keeping in order the vast fund of his observations 

 and the records of those made by others; and he was conscious 

 of the limitations of pure inductive philosophy to an extent 

 which made the conclusions reached by him safe." (Frazer.) 



During the Civil War Dr. Leidy acted as surgeon of the 

 Satterlee Hospital in Philadelphia. Leidy's name is not only 

 remembered by his remarkable contributions to anatomy, 

 paleontology, and other sciences, but in the lofty Rockies stands 

 " Mt. Leidy," named by Dr. Hayden, the distinguished explorer 

 and geologist; and " Cape Leidy," on the coast of Grinnell Land 

 is a token of the devotion of Drs. Kane and Hayes to their college 

 friend.
