birds. The collection of mounted skeletons has been further 

 increased by the return of materials sent to Prof. Ward for 

 preparation. Mr. Kappeler has also added many fine casts 

 of rare or unique specimens of extinct mammals. To the 

 series of casts have been added by purchase casts of the 

 Glyptodon, of the remains of Sivatherium, of various species 

 of JElejphas, Mastodon, Rhinoceros, Bos, Castoroides. etc. 



A portion of the cases in the large exhibition room having

 of mammals has been commenced, and in a few weeks will 

 doubtless be completed as far as our present limited space 

 will allow.
