MUSEUM OF COMPARATIVE ZOOLOGY. 29 



through the whole year, and is to be designated Zoology 9 ; it will 

 be somewhat similar to the course Geology 13 of previous years, 

 this course being discontinued. 



It is with regret that I record the resignation of Dr. W. McM. 

 Woodworth from the teaching force of the Department, to take 

 effect at the beginning of the next Academic year. I wish to 

 express the feeling of loss which we as a Department experi- 

 ence in the transference of Dr. Woodworth's energies from the 

 College to the Museum, which is hereafter to receive all his atten- 

 tion, and further, to express the hope that at some time in the 

 future a portion of his time may be again given to the work of 

 instruction. 



To provide for the work in teaching hitherto carried on by Dr. 

 Woodworth, and at the same time to relieve Dr. Parker of a 

 portion of his duties in instruction, Dr. William E. Castle has 

 been appointed Instructor in Anatomy and Embryology. Besides 

 assisting in the courses in Microscopical Anatomy and Embry- 

 ology of Vertebrates (Zoology 4 and 5), he will have charge of 

 Zoology 2. 



Dr. Davenport, in addition to the work which he has done in 

 connection with the courses under his charge and the papers pro- 

 duced in connection with them, has published Part I. of his work 

 on " Experimental Morphology." This part deals with " Effect 

 of Chemical and Physical Agents on Protoplasm," and is a book 

 of nearly 300 pages, issued by the Macmillan Company, New York, 

 1897. Part II. of this work is also nearly completed. He has 

 also published an article " On the Role of Water in Growth," as 

 Contribution No. LXXX., and, in collaboration with Mr. C. Bul- 

 lard, Contribution No. LXXIII. He has besides written for 

 " Science v a review of the works of 0. Hertwig and E. B. Wilson 

 on " The Cell," and several reviews for " L'Anne'e biologique," 

 Tom. I., as well as an article on "College Admission Require- 

 ments" for the "Harvard Graduates' Magazine," December, 1896. 



Dr. Parker has published two interesting illustrated papers : one 

 on " The Mesenteries and Siphonoglyphs in Metridium," the other 

 on " Photomechanical Changes in the Retinal Pigment Cells of 

 Palsemonetes," etc., as Contributions LXXY. and LXXVI. 



The paper on " Some Variations in the Genus Eucope," by the 

 Curator and Dr. Woodworth, has been published since my last 

 Report, and Dr. Woodworth has also published an article " On a
