REPORT ON OSTEOLOGY. 



By D. D. Slade. 



This department has received no important additions since the 

 last annual report. 



The collections remain in excellent condition, and have re- 

 ceived neither damage nor loss. 



Several specimens have been received for identification, and 

 two small collections from different sources, which were offered 

 during the vacation, have not yet been determined. 



Instruction by means of lectures, examinations, and laboratory 

 work has been given during the academical year to five students, 

 three of whom were undergraduates, one was a Graduate, and 

 one a Lawrence Scientific Student. The work performed by 

 them has been generally satisfactory. 



The Assistant hopes to make the course of instruction during 

 the coming year one in which research will receive more atten- 

 tion than heretofore. 



The following papers have been published by me during the 

 past year : — 



Osteological Notes. The Jugal Arch in the Order Insectivora. Science, 

 Vol. XIX. p. 203. 



Osteological Notes. The Jugal Arch in the Order Rodentia. Science, 

 Vol. XX. p. 46. 



Some of the orders in the collection of disarticulated skeletons 

 are still sadly deficient in specimens, — a want which can only 

 be supplied through the generosity of some patron who under- 

 stands the importance of this department to the scientific 

 student.
