REPORT ON THE OSTEOLOGICAL DEPARTMENT. 



By D. D. Sladb. 



The collection has received no additions during the past year, 

 although such would be very desirable, especially in the orders 

 of the Insectivora and Cheiroptera. It has been consulted by 

 gentlemen connected with the other departments of the Univer- 

 sity for the purposes of special study and comparison. Occasional 

 specimens have been brought in by strangers for determination. 



The entire collection is in good condition, and has received no 

 material damage by its use for illustration and study. No speci- 

 mens have been lost. 



A paper in Science, July 25, 1890, on " The Absence of the 

 Patella in Marsupials," has been published ; also nearly ready 

 for publication, u The Significance of the Zugal Arch in the 

 Mammalia."
