ceived many honors from American and European. scientific so 
cieties. The long list of them will be found in the careful and 
admirable memoir of Dr. H. C. Chapman in the Proceedings of 
the Academy of Natural Sciences for June 30, 1891, to which I 
am indebted for the statistical information as to his early life 
given above. 
Among these honors, however, his unanimous and enthusiastic 
election as President of the Academy of Natural Sciences in 1881; 
his installation as Director of the Biological department of the 
University of Pennsylvania in 1884; his election as President of 
the Wagner Free Institute of Science; and the degree of LL. D., 
which he received from Harvard in 1886; the gift of the Walker 
prize of $500 from the Boston Society of Natural History raised 
to $1,000 as a special recognition of his great services to science; 
the prize of the Royal Microscopical Society in 1879; the Lyell 
medal by the Royal Geological Society in 1884; and the Cuvier 
medal from the Academy of Sciences in Paris in 1888 should not 
be forgotten. 
Dr. Leidy was elected a member of the National Academy of 
Science in 1884. 
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 ren- 
dered almost every observation he made directly or indirectly an 
addition to science. In all that pertained to the acquisition of 
facts and to cobrdinating 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 marvellous eye for noting 
the minutest phenomena and appreciating the most insensible dif- 
ferences; 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. It is usually said that he 
never made an enemy. This seems to be too much to say, for ene- 
mies are made by the very fact of superiority, and ne doubt this 
great man had them, but if so they were prudent enough to refrain 
from declaring themselves. He would never quarrel, and his de-
