8 ANNUAL REPORT OF THE 



There has been no change during the year in instructors, nor in 

 their rank, and the courses have been carried on in most cases 

 substantially as in the preceding year. The assistants in the sev- 

 eral courses are named in connection with the statements about 

 the work of the courses. 



In Zoology 1 the students have been required, as in 1901-02, to 

 concentrate their laboratory work. Professor Parker has had as 

 Chief Assistant Mr. R. S. Breed, and- as Sub-Assistants, Messrs. 

 Grant Smith, Chauncy Juday (who was early obliged to withdraw 

 from the University on account of serious sickness), and J. M. 

 Johnson. The Assistant in the course given to students of Rad- 

 cliffe College was Mr. C. W. Halm. It is proposed hereafter 

 to devote half an hour of each three-hour laboratory exercise to an 

 informal review and quiz. 



The lectures in Zoology 2, by Dr. Castle, were substantially 

 like those of previous years. The laboratory exercises were 

 somewhat changed. The flat-worm type was studied in perma- 

 nent entire preparations and in prepared sections of the ectopara- 

 site Bdelloura. By shortening somewhat the time hitherto de- 

 voted to the anatomy of the frog, it was possible to give some 

 attention to the external features of the metamorphosis of the 

 tadpole. The Chief Assistant in the course was Mr. A. W. 

 Peters, the Sub-Assistants Messrs. C. H. Lander and J. A. Long. 

 The Assistant in the course given to Radclifle students was Mr. 

 Grant Smith. 



The number of lectures in Zoology 3 was increased from sixty- 

 one, the number given in 1900-01, to sixty -six. The course was 

 attended by a larger number of students than in any previous 

 year, forty-one having been enrolled. The laboratory work was 

 with the same representatives of the classes of vertebrates as pre- 

 viously, except that the cat was dissected in place of the rabbit, 

 satisfactory arrangements having been made for procuring mate- 

 rial. Dr. Rand had as Chief Assistant Mr. F. W. Carpenter; as 

 Sub-Assistant, Mr. M. E. Stickney. The Assistant in the corre- 

 sponding Radcliffe College course was Mr. W. P. Hager. It is 

 hoped that in the future some time spent by students in the rou- 

 tine labor of preparing skeletons can be saved by providing mul- 

 tiple sets of certain of the skeletons studied. 



In Zoology 4 less attention than usual was given in the lectures 

 to bibliographic methods. In the laboratory fewer methods were 

 employed and more time given to the study of preparations of the
