 thirds courses; Zoology 20g, under Professor Rand, one and one 

 third courses; in Radcliffe Zoology 20c, under Professor Parker,

Miss Marion Irwin, graduate student in Radcliffe College, re- 

 ceived in June the degree of Ph.D., her thesis, partly in the field 

 of botany, partly in zoology, being entitled : — Effect of electrolytes 

 and non-electrolytes on organisms in relation to sensory stimula- 

 tion and respiration. 



The exigencies of war had made it necessary late in the year 

 1917 to transfer the Bermuda Biological Station from Agar's to a 

 near by island — Dyer Island. 



At the opening of the College late in September, 1918, it was 

 decided by the Corporation that, in view of the uncertain duration 

 of the war, it would be desirable to close the Station for the time 

 being. Accordingly when the Resident Naturalist, Dr. W. J. 

 Crozier, received an offer of an Assistant Professorship in the 

 College of Medicine of the University of Illinois, the Station was 

 closed and so remained from early in November 1918, till June 

 1919, when it was reopened on Agar's Island. The Station was 

 open from 28 June to 10 September, and six persons, four of them 

 from Harvard, including the Director, were at work there during 

 most of the time. 



At the Marine Biological Laboratory, Woods Hole, the Harvard 

 Table was shared by two graduate students pursuing researches. 

 The Radcliffe Table was shared by two students of the classes of 

 1919 and 1921. 



Aid from the Humboldt Fund to the amount of $417.50 was 

 furnished to research students at the Bermuda Station and the 

 Woods Hole Laboratory, the payments falling, however, within 

 two fiscal years. 



The meetings of the Zoological Club were discontinued during 

 the first term; but during the second and third terms there were 

 thirteen meetings at which five original papers and eleven reviews 

 were presented. The average attendance was over fourteen. 



The Contributions from the Zoological Laboratory and from 

 the Bermuda Biological Station for Research for the year 1918-1919 

 are listed on p. 30-32; other papers under the authors' names.
