REPORT ON THE OSTEOLOGICAL DEPARTMENT. 



By D. D. Slade. 



Several valuable additions have been made to the collection 

 since the last Report. Among the articulated skeletons, mention 

 should be made of the fine specimens of Balaena cisarctica, Phy- 

 seter macrocephalus, and Monodon monoceros, all of which have 

 been suspended in the main Exhibition Hall. The extreme rarity 

 of the Chlamydophoridse among the Edentata renders the recent 

 possession of C. truncatus a most valuable acquisition. The dis- 

 articulated skeletons also comprise several of much interest to the 

 scientist and student. The entire collection is in good order and 

 preservation, and, while extremely valuable, is still sadly deficient 

 in many of the orders. Attempts have been made by the Assist- 

 ant, during the last few months, to induce some of the wealthy 

 friends of the University to contribute to a fund for the care and 

 increase of the collection, than which none can be more useful 

 and important in the pursuit of a scientific education. Although 

 not so successful as he could wish, perseverance may produce good 

 results in the near future. 



Instruction has been given in Comparative Osteology during the 

 past year by means of lectures, laboratory work, and by frequent 

 examinations. The course has been attended by three Seniors and 

 by one Junior. 



While this course, Zoology 10, is usually selected by those who 

 have the medical profession in view, it presents rare opportunities 

 for special study and research, both to the graduate and under- 

 graduate. 



The following papers have been published during the year : — 



The Significance of the Jugal Arch. Science, Vol. XVI. p. 332. 



The Jugal Arch in the Primates. Science, Vol. XVII. p. 317, and Vol. 

 XVIII. p. 53. 



On the Genus Chlamydophorus. American Naturalist, June, 1891, 

 p. 540.
