REPORT ON THE ZOOLOGICAL LABORATORY. 



By E. L. Mark. 



The courses in Zoology offered for the year 1917-1918 were, 

 with the exception of those given in alternate years, the same as in 

 1916-1917, and were conducted by the same instructors; but the 

 opportunity for laboratory work in Zoology 8 was withdrawn. 

 As in the previous year, and to a greater extent, the numbers in 

 courses were affected by the war, the total number of registrations 

 in Harvard being about thirty per cent less than in 1916-1917. 



Tables I and II give the statistics regarding each of the courses 

 in Harvard and in Radcliffe College, respectively.
