360 ENTOMOLOGICAL NEWS. [February, 



other microscopic animals, through the earthworm, clam, squid, 

 lobster, star-fish, sea-urchin, shark, frog and pigeon, to the cat, 

 are dissected, studied and drawn. Previous to the dissection of 

 any form a short lecture is given, which, supplemented by a full 

 list of laboratory guides and text-books, gives the student a 

 sufficient knowledge to enable him intelligently to study the 

 creature before him. Each man provides himself with a set of 

 dissecting instruments and note books, but all other apparatus 

 and books are owned by the laboratory. During the Winter 

 term a series of thirty lectures is given, covering the entire 

 subject of zoology, except that portion having reference to the 

 insects, which, because of their importance, are treated as a 

 separate science. The aim here is to supplement and render 

 orderly the knowledge a'lready gained through the medium of 

 the microscope and scalpel, and the lectures are abundantly 

 illustrated by the very complete museum belonging to the de- 

 partment and containing over twelve thousand specimens. 

 Collateral reading is encouraged, and occasional quizzes are 

 given as a test of the student's knowledge from all sources. 



Entomology. A course of six hours a week is offered in 

 entomology, during the Summer term, its aim being to give a 

 general knowledge of insect anatomy and physiology and a 

 systematic review of the entire group, taking as types, as far 

 as possible, those forms of economic interest to man, and at 

 the same time giving an idea of the life history of each species 

 so taken, and the means of combating it. A knowledge of in- 

 secticides and insecticide machinery and their use is given. An 

 interesting feature of the course is the collection which each 

 student makes and arranges of the more common species which 

 may be found on the college grounds and the nearby region. 

 A very full museum collection serves as an aid to identification 

 and arrangement. 



Senior Entomology. During the senior year such members 

 of this class as elect advanced entomology take a course of lec- 

 tures on the external and internal anatomy of insects and on 

 the various methods by which injurious forms are destroyed or 

 held in check. The laboratory work consists of a critical study
