212 PROCEEDINGS OF THE ACADEMY OF [1895. 



Dr. Ryder's earnestness of purpose and intense interest in his 

 studies could not fail to impress and stimulate his fellow members, 

 while his wonderful memory and obliging disposition were often 

 appealed to by them, and it was very rarely that he could not fur- 

 nish the desired information. Especially was this true of his knowl- 

 edge and recollection of scientific literature ; on many subjects he 

 could give an almost complete bibliography from memory. 



In deeply deploring the early death of Dr. Ryder, which occurred 

 at the height of his scientific vigor, the Section but voices the senti- 

 ment of the entire biological world.
