16 A.NNUAL REPORT OF Till. 



The lectures in Zoology 7a, lb, 1c, and 11 were given at the 

 Museum of Comparative Zoology, the laboratory and field work 

 in these courses at the Bussey Institution. Courses la and lb 

 were given by Professor Wheeler with the assistance of Mr. C. 

 T. Brues; 1c by Mr. Brues. 



The laboratory work in Zoology 1 1 was based partly on zoo- 

 logical, partly on botanical material. The course was conducted 

 jointly by Professor Castle and Assistant Professor East. 



In Zoology 14<7, conducted by Professor Parker, students were, 

 as usual, assigned topics for research or thesis work. Five wrote 

 theses. Two students not enrolled attended the lectures. 



The lectures in Zoology 17, by Assistant Professor Rand, 

 followed the same plan as the year before, but their content was 

 considerably changed, more time being given to experimental 

 embryology and less to regeneration. The results of work on 

 some of the laboratory problems will be presented for publication 

 later. 



For the first time since instruction in Zoology was offered to 

 students in Radcliffe College, the elementary courses have been 

 put in charge of a person not an instructor in Harvard. The 

 department was fortunate in securing Mr. D. W. Davis to take 

 charge of Zoology 1 and 2. Since his graduation from Harvard 

 College in 1905 Mr. Davis has been engaged in teaching, and his 

 management of these two courses has been very satisfactory. 



Professor Mark gave the lectures in Zoology 56 (Radcliffe), the 

 laboratory work being under the general supervision of Assistant 

 Professor Rand, who had as assistant Mr. S. Morgulis. 



Twenty-one graduate students and one undergraduate were 

 engaged in researches, eleven under the direction of Professor 

 Mark, four under Professor Parker, two under Professor Wheeler 

 at the Bussey Institution, three under Professor Castle extending 

 through the whole year, at the Bussey Institution, and two under 

 Assistant Professor Rand. Of these twenty-two persons, two 

 were graduate students of Radcliffe College. Three presented 

 theses for the doctor's degree, and received the degree of Ph.D. 

 The thesis of Edith X. Buckingham was on " The division of 

 labor among ants" that of Sergius Morgulis was entitled " Studies 

 of inanition in its bearing on the problem of growth," and that of 

 William A. Willard " The cranial nerves of Anolis carolinensis."
