EEPORT OF THE PROFESSOR OF ZOOLOGY AND ENTOMOLOGY. 



To the President of the College: 



Herewith I present a report, of the instruction given, and the progress made 

 in my department for that portion of the past College year which has expired. 



Early in the year, my assumed labors more than equaled my strength, so that 

 for more than two months I was nearly disabled from College duties, having lost 

 the use of my voice. During this time I was fortunately able to procure very 

 efficient aid, so that the course of instruction was not broken in upon. I was 

 able most of the time to carry on my other duties, some of the time, however, in 

 an indifferent manner. I also took advantage of my misfortune by taking 

 this time to visit the great Exposition at Philadelphia, and some of the leading 

 museums of the country. 



Owing to a change in the arrangement of the College terms, my instruction 

 has been such as to make the title of my professorship almost a misnomer, the 

 majority of the subjects taught not coming in my department at all. I feel 

 that in view of the increasing duties of my position as Apiarist, and Curator of 

 the Museum, and the disadvantage I labor under in giving instruction in so 

 many subjects entirely foreign to my general thought and study, — Rhetoricals, 

 Book-keeping, History and Mathematics — that some provision for a change is 

 very desirable. 



The Junior class had a course of thirteen weeks in Mechanics. The study 

 was pursued by use of text-book — Snell's Olmstead. The class made very com- 

 mendable i^rogress, the members, without exception, evincing an interest which 

 bore fruit in an excellent scholarship, and most satisfactory examination. The 

 class average was unusually high. The same progress was shown in the study 

 of Hydrostatics, Acoustics, and Optics, during the first half of the second term. 

 The class numbered thirteen. 



I can not close this part of my rej^ort without reference to the excellent man- 

 ner in which the class was conducted by Prof. Carpenter during my sickness. 



The Junior class also had a course of eight weeks in Entomology, during 

 whicli time a course of lectures was given embracing the following subjects : 

 The Anatomy, and Physiology of Insects, their Classifications ; Scientific and 

 Practical Apiculture, and Economic Entomology. In the pursuit of the last 

 two subjects we were aided very much by the use of my ]\Ianual of Apiculture, 

 and my pamphlet on the Injurious Insects of Michigan. 



The members of the class collected and bred insects, that they might the 

 better observe their transformations, and also performed more laboratory work 

 than usual. They dissected, to determine accurately the anatomy of insects. 

 They not only examined under the microscope those portions used in classifica- 

 tion, but also dissected out and carefully examined the digestive, circulatory, re- 

 spiratory, nervous, and reproductory organs. The results of their laboratory 

 work were shown by figures carefully drawn on the black-board and explained 

 to the class. 



During the instruction in Apiculture, the students witnessed all the manipu- 

 lations, such as forming nuclei, dividing colonies, introducing queens, extract- 

 ing, etc., and such as desired — nearly all — actually took part in the operations
