The progress of ornithology in the United States pre- 

 vious to 1876 is well described in a paper by J. A. Allen in 

 the American Naturalist (10, 536, 1876). A sketch of the 

 early history of conchology is given by A. W. Tryon in 

 the Journal (33, 13, 1862). 



Jeffries Wyman was the most prominent comparative 

 anatomist of this period. His work includes classic 

 papers on the anatomy and embryology of fishes, 

 amphibia, and reptiles. 



Zoology in the American Journal of Science, 

 1846-1870. 



The fifty volumes of the second series of the Journal, 

 including the years 1846 to 1870, cover approximately 

 this period of morphology and embryology. During this 

 period the Journal occupied a very important place in 

 zoological circles, for J. D. Dana was for most of this 

 period the editor-in-chief, while Louis Agassiz and Asa 

 Gray were connected with it as associate editors. More- 

 over, in 1864 one of the most promising of Agassiz 's 

 pupils, Addison E. Verrill, was called to Yale as pro- 

 fessor of zoology and was made an associate editor 

 in 1869. 



In the Journal, therefore, may be found, in its original 

 articles, together with its reports of meetings and 

 addresses and its reviews of literature, a f airly^ complete 

 account of the zoological activity of the period. The 

 most important zoological researches, both in Europe 

 and America, were reviewed in the bibliographic notices. 



The most important series of zoological articles are by 

 Dana himself. As his work on the zoophytes and crus- 

 tacea of the U. S. Exploring Expedition continued, he 

 published from time to time general summaries of ^ his 

 conclusions regarding the relationships of the various 

 groups. Included among these papers are philosophical 

 essays on general biological principles which must have
