and Zoology, and continued to fill that of Physiology until 1869. At that time, 

 18G9, Albert J. Cook, tlie present incumbent, a graduate of the College, was 

 appointed professor of Zoology and Entomology. 



A collection of the shells of Michigan, and of its animals and minerals, was 

 commenced by Dr. Miles, who had been the Zoologist of the geological survey 

 of the State. It has been more than doubled under the enthusiastic work of 

 Prof. Cook, and of the many students whom he has inspired with his own zeal. 



The College has on deposit numerous specimens sent us by the Smithsonian 

 Institution at Washington. It is entitled by law to sets of specimens of the 

 geological survey of the State, and many specimens have been received from 

 this source. A small annual appropriation gives a constant but too slow growth 

 to the General Museum. Its means of illustration in Geology and Compara- 

 tive Anatomy are meager. The collection of Michigan birds and animals 

 mounted approximates completeness. Tlie entomological collections are fuller, 

 there being about thirty cases of insects. A large part of the preserving and 

 mounting of animals has been done at the College by students, under the di- 

 rection of Dr. Miles or Prof. Cook, or by those who had made some special 

 study of the art. The value of the General Museum, a museum excluding 

 the collections in Botany, Chemistry, Agriculture, and other special depart- 

 ments was, Sept. 1877, $5,193.26. Five hundred dollars have been spent upon 

 it since that time. 



The Natural History Society of tlie College has a museum of its own, con- 

 taining many excellent specimens. 



The instruction given in Physiology extends through one term daily lessons. 

 Special attention is given to the comparative anatomy and physiology of domes- 

 tic animals. The students are taught to dissect animals and to study the tis- 

 sues under the microscope. 



Entomology takes a term of study with daily lessons, and Zoology and Anat- 

 omy together occupy a third term. In Entomology particular study is made 

 of insects injurious to vegetation. The students dissect and learn to make 

 accurate drawings of the peculiarities which are important in determining fam- 

 ilies and genera. 



Professor Cook has been able to secure through the graduates a corps of good 

 observers of insects and their works in various parts of the State. He is almost 

 flooded with insects and inquiries that pour in upon him regarding them through 

 the mails. The insects often come in the larva state, and have to be fed and 

 developed into the winged state before they can be described. He has given 

 many addresses, and written largely for the press regarding injurious insects. 

 In 1874 he printed a thick pamphlet on injurious insects, — the same forming a 

 part of the report of the Board of Agriculture for that year, — which was widely 

 circulated amongst farmers, as they expressed a desire for it. In 1875 the 

 army worm, in 1876 the bot-fly, the pork-worm, in 1877 the Hessian fly and the 

 insects that attack our timber and shade trees, received his attention, and his 

 winter institute lectures on them will be found in the reports of the ]3oard. In 

 other words, this department, like all the other departments of the College, 

 attempts while teaching science purely to teach its })rinciples at the same time 

 with distinct reference to agriculture, as befits an agricultural college. 



APIAKY. 



A special subdivision of the department is the Apiary. The College has a 

 separate building for the apiary, witli grounds on which grow specimens of
