advisability of making the course in Biology cover two years. 

 This would raise the character of the advanced courses in Botany 

 and Zoology, and tend to relegate them to the graduate courses. 



The course in Biology last year was attended by thirty-six 

 students (one Freshman, four Sophomores, sixteen Juniors, eight 

 Seniors, one student in the Lawrence Scientific School, one candi- 

 date for the degree of A.M., and five unmatriculated students). 

 Most of these students intend to study medicine. 



Nine hours a week are required of each student. 



The third course (Advanced Zoology) can be followed in the 

 future only by those who have passed the examinations in Biology. 

 The members of the class last year had during the preceding 

 year taken a general course in Elementary Zoology, and were 

 thus prepared to study more thoroughly certain groups of 

 animals. The early part of the year was devoted to the study of 

 the morphology of the class of Crustacea. The students being 

 few in number, it was found practicable to place the amplest 

 amount of material in their liands, and to deal with the mor- 

 phological problems with a delightful freedom from diagrams and 

 text-books. The interest shown by the students in their work 

 was attested by the fact that some of them of their own accord 

 embodied the results of their studies in original essays, which were 

 presented before the Harvard Natural History Society. 



The Radiates were next taken up in a similar way ; and the 

 last third of the year was devoted to the study of the development 

 of the chick within the egg. 



This course was taken by three Seniors, one Junior, and one 

 student of the Lawrence Scientific School, — nine hours a week 

 throughout the year. 



The fourth course consists of one lecture a week on Human 

 Physiology. It is a voluntary course, open to all students of the 

 University. About thirty students attended the lectures during 

 the last year. 



In addition to these four courses given last year, a course in 

 Entomology (with laboratory work), by Prof. H. A. Hagen, is 

 offered to graduates who are properly qualified to pursue the 

 study. This course was not given last year, having, accidentally 

 been omitted from the list of electives. 



The Museum assistants are also allowed to take students 

 specially qualified in any special department of Zoology or 

 Palaeontology. 3
