collaboration with Agassiz, published a text-book for schools 

 on the principles of zoology. He also edited the unfinished 

 work of his friend, Dr. Amos Binney, on the terrestrial air- 

 breathing mollusks of the United States. 



Dr. Gould made his greatest contribution to natural history 

 by the work done on the collection made by Captain James P. 

 Couthouy, U. S. N., when attached to the United States Explor- 

 ing Expedition. As all the notes were lost, and various restric- 

 tions were made as to the manner of doing the work, the task was 

 a perplexing one. 



Besides his papers on natural history, which number more 

 than 100, he also published medical addresses and reports, 

 which were of great value to his profession. He was President 

 of the Massachusetts Medical Society, and for several years 

 consulting physician of the Massachusetts General Hospital. 

 The church to which he belonged, and the public schools were 

 benefited by his labors. Untiring in his work he was still hoping 

 to attain better results as a physician and naturalist, when he was 

 suddenly attacked by cholera, and died on September 15, 1866.

 1824, he received his early education from his father, a teacher 

 of acknowledged merit, and entered Harvard College in 1844. 

 For a short time after graduation, he was head-master of the 

 Roxbury Latin School. Though early in his college course he 

 showed a fondness for the classics, the later years were devoted 

 largely to mathematics, and he thus laid the foundation for his 

 future work. 



In 1845 Gould went to Europe, and spent three years in 

 astronomical study at Berlin, Paris, Gottingen and other cities. 

 He received the degree of Doctor of Philosophy from the
