No. 4.] AGRICULTURAL COLLEGE. 187 



Department of Zoology. 



The work in this department begins in the winter term of 

 the sopliomore year, with human anatomy and physiology, 

 the study of which not only serves as an introduction to the 

 more advanced work later in this department, and in vet- 

 erinary science, but also gives the young men a knowledge 

 of the structure and uses of the ditierent organs of the human 

 body and the laws of health. In the fall and winter terms 

 the members of the junior class take zoology, which is taught 

 by means of lectures and laboratory work. In the labora- 

 tory each member of the class dissects and studies a series 

 of typical animals, making drawings of the various organs. 

 During the spring term of this year a course of lectures is 

 given on insects in general, their classification and habits 

 and the various methods of destroying those that are in- 

 jurious. There is a most excellent museum connected with 

 this department, in which are exhibited, as far as possible, 

 all the animals that occur in this Commonwealth, together 

 with such species from other parts of the world as are neces- 

 sary to give completeness, or are useful for the instruction 

 of the students. This museum furnishes specimens for illus- 

 tration in the lectures before the classes, and also for general 

 information to all visitors as well as members of the college. 



During the senior year such members of the class as elect 

 advanced entomology take a course of more technical lectures, 

 in which the following subjects relating to insects are con- 

 sidered quite at length : external and internal anatomy, em- 

 bryology, transformations, duration of life, luminosity of 

 insects, the color of insects, parasitic insects, diseases of 

 insects, number of insects in existence, geographical and 

 geological distribution, insect architecture, fertilization of 

 plants by insects, economic entomology, bee-keeping and 

 the literature of insects. The laboratory work of this year 

 consists in part of the dissection of a caterpillar, a pupa and 

 a moth, and a critical study of the external anatomy of a 

 number of each of the orders of insects, followed by the ex- 

 ercise of determining a group of insects in each order ; and, 

 finally, each student is required to prepare a thesis on some 

 insect or group of insects pertaining to the business in which 

 he intends to engage. Each member of the senior class who
