Schools of Applied Science, and three in Radcliffe College. Three 

 were enrolled in Zoology 20b under Professor Mark, six in Zoology 

 20c under Professor Parker, four in Zoology 20d under Professor 

 Castle, five under Professor Wheeler in Zoology 20f, and two each 

 in Zoology 20e and Zoology 20g under Professor Rand. Two of 

 these fulfilled the requirements for the degree of Doctor of Phi- 

 losophy. Mr. Reynold Albrecht Spaeth, whose thesis was on The 

 physiology of the chromatophores of fishes, received the degree 

 in February; and Mr. James Watt Mavor, whose thesis was en- 

 titled Studies on Myxosporidia found in the gall bladder of 

 fishes from the eastern coast of Canada, in June. Mr. Donald 

 Walton Davis, the title of whose thesis was given in the report a 

 year ago, also received the degree in February. 



Three students, two in Harvard and one in Radcliffe, were 

 granted aid from the income of the Humboldt Fund to the amount 

 of $185.16, while pursuing work at the Bermuda Biological Station. 

 In the Bermuda Biological Station for Research there were enrolled 

 nine persons, four of whom were connected with Harvard and one 

 with Radcliffe. The Station was open from June- 6 till August 5. 



In January, Professor Parker read a paper on Adaptation 

 in animal reactions, at the Cleveland meeting of the American 

 Society of Naturalists, and in February, lectured on The Evolu- 

 tion of the nervous system, at the Vassar Brothers Institute, 

 Poughkeepsie. In May, he delivered an address entitled A bio- 

 logical forecast, at the annual banquet of the Brown University 

 chapter of the Sigma Xi Society. 



Eighteen meetings were held by the Zoological Club, at which 

 seventeen original papers and reviews of nine others were read. 

 A complete record of the attendance was not kept by the Secretary, 

 but the estimated average attendance was about twenty.
