REPORT ON THE ZOOLOGICAL LABORATORY. 



By E. L. Mark. 



During the Academic year 1907-08 the following changes have 

 taken place in the Department of Zoology. Assistant Professor 

 Castle has been promoted to a full professorship. A professorship 

 of Economic Entomology has been established and the chair has 

 been filled by the appointment of Dr. William Morton Wheeler. 

 By the assignment of an additional Austin Teaching Fellow to 

 the Department it has been possible so to arrange the work that 

 Dr. Rand will have more time for research and the opportunity 

 to offer an advanced course in a subject in which he is especially 

 interested — "Morphogenesis. The Dynamics of Development 

 and Growth." An Instructor in Entomology is also to be added 

 to the staff. The great advantage secured by these changes and 

 additions is the increased amount of time which will be given to 

 original investigations, especially by Professors Wheeler and 

 Castle. 



As in previous reports, the first of the accompanying tables 

 exhibits the number of students attending each of the courses in 

 Zoology offered during the year. The numbers printed in italics 

 refer to students in the Lawrence Scientific School and in the 

 Graduate School of Applied Science. The second table gives 

 corresponding information relative to Radcliffe College.
