ill various official positious ever since, and has been its President 

 since 1880. Dr. Leidy i)iiblished very extensive memoirs on verte- 

 brate paheontology, on Rhizopods (a truly magnificent quarto vol- 

 ume), on the anatomy of Insects, and especially on Entozoa and 

 Vermes generally. Indeed, nearly every branch of zoological lit- 

 erature has received valuable additions at his hands. His work is 

 so many-sided that in the broadest sense of the word, Dr. Leidy 

 may be called a Zoologist. He was an honored member of many 

 scientific societies in both hemispheres, and had received substan- 

 tial tokens of the value of his work from the Boston Society (Wal- 

 ker Prize, $1000), the Geological Society of London (Lyell Medal), 

 and other learned bodies. 



In his private relations Dr. Leidy was of a most kind and help- 

 ful disposition. He had an almost morbid dislike of contention of 

 any kind. The loss to American zoology is irreparable.
