442 PROCEEDINGS OF THE ACADEMY OP [1879. 



Mr. Spencer Trotter has also been engaged in the arrangement 

 of the birds. 



The collection of vertebrate fossils from the New Jersey cretace- 

 ous and tertiary marls, which are very liable to decomposition from 

 exposure to the air, have been treated so as to preserve them, and 

 the} r have been arranged and labeled. 



Most of the specimens received during the year have been 

 placed in their proper positions in the various collections. 



The most important addition to the Museum during the year, 

 consists of the Archaeological collection belonging: to the Aineri- 

 can Philosophical Society, deposited with the Academy by reso- 

 lution of Nov. 16, 18*17. The collection mainly consists of the 

 Poinsett collection of Mexican antiquities and many Peruvian 

 and other American antiquities. The Academy is indebted to 

 Mr. William S. Vaux, for defraying the expense of adapting one 

 of the entresol rooms to the proper exhibition of the collection.
