All these students have been taught the outlines of Zoology, 

 by the study of typical forms from the most important groups 

 of animals. Those who were fitted for more advanced study, 

 have been put in the way of making special investigations. 



Instruction in my department in microscopy, under the super- 

 intendence of Mr. Tuttle, has also been provided for beginners 

 and for advanced students. This teaching extends over one- 

 half of the year, and enables the student to become master of 

 the practical detail of microscopic work, so far as is required in 

 all ordinary investigations. 



A course of elementary instruction in the study of insecfs has 

 been given by Mr. Edward Burgess, who has acted as college 

 instructor in this branch. 



The following courses of lectures have been given as a part 

 of the above-mentioned instruction : — 



A course of about one hundred lectures on Zoology, by Mr. 

 Shaler. 



A course of lectures on Palaeontology, by Mr. Shaler. 



A course of Readings, with commentary, intended as an intro- 

 duction to the history of modern Zoological opinions, by Mr. 

 Shaler. 



A course of lectures on the use of the Microscope, by Mr. 

 Tuttle. 



A course on Entomology, by Mr. Burgess. 



I am also indebted to Dr. Hagen, Dr. Maack, and Mr. A. R. 

 Crandall, for assistance given to particular students in the prose- 

 cution of especial parts of their work. 



During the summer an excursion of two months duration was 

 made, from Cambridge to the James River, in Virginia. Stu- 

 dents in the Zoological department were allowed to join this 

 expedition, in which opportunities were afibrded for becoming 

 familiar with palaeontological and zoological work, as conducted 

 in the field. 



Report of J. B. Perry, on the Palceontological Collection. 

 The earlier portion of the year was mainly devoted to the 

 re-organization of the Museum library. Attention to this in- 

 terrupted, of course, my more special work, viz., the systematic 

 arrangement of the Tertis^ry Gasteropods.
