REPORT ON THE ZOOLOGICAL LABORATORY. 



By Professor E. L. Mark. 



As no formal report since that for the year 1897-98 has 

 been printed, the present report will cover the academic years 

 1898-99 and 1899-1900. 



Owing to the absence of Professor Mark in Europe during the 

 year 1898-99, the work of the Department was to some extent 

 rearranged. Course 2 was given jointly by Doctors Parker and 

 Castle. Dr. Castle took charge of courses 4 and 5, and the duty 

 of supervising research students was shared by Doctors Daven- 

 port, Parker, and Castle. 



The numbers of students from the several classes in the various 

 courses of the Department are shown as usual in the following 

 table, to which is added for convenience of reference the number of 

 students in the corresponding courses given in Radcliffe College.
