Woods Holl have provided both the opportunity ani the inspira- 

 tion for the pursuit of numerous researches. Two papers have 

 be^n published as the result of these studies: -- "The 'Jses of 

 Por-naliehyle in Animal Morphology", and "The Nerve-Cells of the 

 Shark's Brain". 



Since my appointment as an Instructor in 1^92, the Univer- 

 sity of Iowa has ^^radually advanced me to positions of larger 

 and larger responsibility, culminating in my election to the 

 Professorship of Animal Morphology and Physiology in June 1897, 

 a position which I still hold. At my urgent request, I was 

 granteJ leave of absence in September 1900 for a year of grad- 

 uate study. I have chosen to spend tnat year at the Johns 

 Hopkins University. 



I hold membership in The American Morphological Society, 

 The American Society of Matjralists, and The Iowa Academy of 

 Sciences.
