in any of the courses of instruction as compared with the pre- 

 ceding year. Minor changes are noted in connection with the 

 accounts of the several courses. 



In Zoology 1, given by Professor Parker, the lectures on Evolu- 

 tionary Zoology were rewritten and illustrated by living guinea- 

 pigs and rabbits belonging to the laboratory, and reared by 

 Professor Castle. The work of students in the laboratory has 

 been facilitated by improved accommodations for storing separately 

 the material and notes of each student, and a case has been built 

 and placed in the lecture room for such illustrative material as is 

 most used in this course. By this means the janitor will be 

 spared much time hitherto employed in transporting specimens 

 from the fourth to the first floor and back again. 



The Chief Assistant in this course in Harvard College was 

 Mr. Grant Smith; the Sub- Assistants, Messrs. I. A. Field, A. D. 

 Howard, and S. 0. Mast. The Assistant in Radcliffe College was 

 Mr. J. A. Long. 



The number of lectures in Zoology 2, given by Professor Castle, 

 was slightly increased (to thirty-six). To the animals studied in 

 the laboratory was added Amphioxus, the time for this being taken 

 from the time heretofore given to the study of the frog. The 

 Chief Assistant in the course was Mr. L. J. Cole, Austin Teaching 

 Fellow, whose place was taken during his absence for a consider- 

 able part of the second half-year in Yucatan, by Mr. J. H. 

 McClellan. The Sub-Assistants were Messrs. D. W. Davis and 

 I. A. Field. 



Dr. Rand conducted, as previously, Zoology 3. The lectures were 

 substantially as in the preceding year, but in the interest of stu- 

 dents wishing to take, in the second half-year, work in Neurology 

 (Zoology 15) the lectures on the nervous system were transferred 

 from the second to the first half-year. Mr. A. P. Larrabee was 

 Assistant in the laboratory work. One student, Mr. J. L. Ulrich, 

 undertook, jointly with the instructor, the study of a special 

 problem in anatomy, the results of which will be later offered for 

 publication. Some progress has been made in increasing both the 

 demonstration material and that designed for use by students in 

 their laboratory exercises. Dr. Rand believes that the course 

 might be considerably improved by a plan which would diminish 

 slightly the number of lectures, and increase the number of con- 

 ferences, so that the correlation between laboratory exercises and 

 lectures could be made- more evident and instructive.
