Opportunities for war service prevented students who had 

 planned to spend a portion of the summer at the Bermuda Biologi- 

 cal Station from going there, so that the Resident Naturalist, 

 Dr. Crozier, and his family were the only occupants. 



The Harvard Table at the Marine Biological Laboratory, Woods 

 Hole, was occupied by a research student, studying problems in 

 experimental zoology, and the Radcliffe Table was shared by an 

 unclassified student taking the course in physiology, and a gradu- 

 ate taking the course in botany. 



The Zoological Club held twenty-two meetings, at which sixteen 

 original papers and twenty-one reviews were presented. 



Lists of the Contributions from the Zoological Laboratory and 

 from the Bermuda Biological Station for Research for the year 

 1917-1918 are given on pp. 30, 31 ; other papers by members of 

 the Department are listed under the authors' names.
