REPORT ON THE INSTRUCTION IN ZOOLOGY. 



By E. L. Mark. 



The instruction in Zoology during the Academic year 1892-93 

 has been substantially the same as that of the previous year, the 

 only exception being a change in the course in Osteology by Dr. 

 Slade, which is now conducted as a research course (Zool. 20 c). 



The accompanying table shows the number of students by classes 

 in each of the zoological courses : —

The laboratory work in Zoology 1 was under the immediate 

 supervision of Mr. H. M. Kelly, the Assistant during the previous 

 year, who had as sub-assistants Dr. H. S. Pratt, and Messrs. 

 J. H. Gerould, H. L. Jones, C. A. Kofoid, and A. G Mayer. 



The department was also fortunate in being able to retain for 

 another year the services of Mr. W. S. Nickerson as Assistant in 

 Zoology 2. The number of students in Zoology 3 necessitated the 

 employment of an assistant in that course, — Mr. W. A. Lecompte. 

 Each of the students wrote a thesis in connection with and sup- 

 plementary to the routine dissections of the course on a problem 

 in comparative anatomy. 



As usual, Dr. W. McM. Woodworth assisted in the laboratory 

 work in Zoology 4 and 5, and gave a portion of the lectures in the 

 former course. The number of students in these courses exceeded 

 the accommodations in room 2, and it was necessary to divide the 

 class for laboratory work into sections, and assign them to different
