Interest in the evolutionary theory continued to 

 increase and eventually developed into the morpholog- 

 ical and embryological studies which reached their cul- 

 mination between 1885 and 1890 under the guidance 

 of Whitman, Mark, Minot, Brooks, Kingsley, E. B. Wilson 

 and other famous zoologists of the time. In these years 

 the Journal of Morphology was established and the 

 American Morphological Society was formed. 



The morphological, embryological and paleontological 

 evidences of evolution as indicated by homologies, devel- 

 opmental stages and adaptations were the most absorb- 

 ing subjects of zoological research and discussion. 



The third series of the -Journal (1870-1895), likewise 

 including fifty volumes, embraces this period of zoologi- 

 cal activity in morphological and embryological studies, 

 culminating with the inception of the modern experimen- 

 tal methods. 



In this period also occurred the greatest progress in 

 marine systematic zoology, due to the explorations of the 

 United" States Fish Commission off the Atlantic Coast, 

 The Journal had an important share in the zoological 

 development of this period also, for A. E. Yerrill, who 

 was now an associate editor, was in charge of the collec- 

 tions of marine invertebrates. Consequently most of the 

 discoveries in this field were published in the Journal in 

 numerous original contributions by Yerrill and his asso-
