 honorary member of the New York Academy of Sciences in 

 1898. He was also a member of the American Society of

As a result of his investigations on the development of the 

 oyster, he was appointed by the governor of Maryland to be 

 chairman of the Oyster Commission of that State; and he 

 was also made Member Protector, Classe Peche et Pissicul- 

 ture d'Exposition universelle d'Anvers ; he also received the 

 medal of the Societe d'Acclimatation of Paris for his oyster 

 work. A Challenger medal was given him for his work on the 

 Challenger Reports ; and he received a medal at the St. Louis 

 Exposition of 1904, where he gave one of the principal ad- 

 dresses. He was Lowell Lecturer in Boston in 1901 ; one of 

 the speakers at the American Museum of Natural History on 

 me occasion of the unveiling of busts of American men of 

 science during Convocation Week, 1906; and he gave one of 

 the principal addresses at the Seventh International Zoological 

 Congress in Boston, in 1907. 



For nearly twenty years he was a trustee of the Marine 

 Biological Laboratory at Woods Hole, Massachusetts; and in 

 1888 he was Scientific Director of the U. S. Fish Commission

 Chesapeake Zoological Laboratory; co-editor, with Professor 

 Martin, of the Studies from the Biological Laboratory of the 

 Johns Hopkins University ; editor of the Memoirs from the 

 Biological Laboratory, and a member of the board of editors 

 of the Journal of Experimental Zoology. 



All of these honors he prized highly, though modestly, and he 

 rarely mentioned them except in facetious vein. It was charac- 

 teristic of him, however, that he not infrequently mentioned 

 with pride the fact that he held a U. S. Inspector's Certificate, 

 licensing him as a pilot.
