Professor Parker was appointed Acting Director of the Ber- 
muda Biological Station for Research for the summer of 1905. 
Besides Mr. John F. Cole, who carried on for the Station mag- 
netic observations during the months of March and April, there 
were twelve biologists enrolled. Of these, seven were University 
instructors, three in Harvard and one each in the University of 
Pennsylvania, the University of Cincinnati, Washington [State] 
University and Syracuse University. 
The conditions which necessitated retrenchment during the 
year 1903-04 still continue, and weigh heavily on the Department. 
It is proposed to amplify somewhat in the future the instruction 
in some of the courses by presenting in alternate years different 
portions of the fields now more or less completely covered each 
year. For the coming year Professor Mark’s lectures on Embry- 
ology of Vertebrates will be devoted to Organogeny (Zodlogy 6), 
leaving the Early Stages of Development (Zodlogy 5) for 
1906-07. In like manner Professor Parker’s lectures on Com- 
parative Histology will deal with Epithelial and Nervous Tissues 
in 1905-06, and with Muscular and Sustentative Tissues the 
following year. Professor Castle proposes to divide each of his 
alternating courses (Zodlogy 10 and 11) into half-courses (10a, 
106, and 11a, 116), which may be taken separately, and to change 
somewhat the ground covered. Course 11a, to be given in the 
first half of the coming year, will be devoted to Variation, 
Heredity, and the Principles of Animal Breeding. Course 114, 
in the second half-year, will deal with the Natural History of
