1865.] SENATE— No. 96. 15 



continued the exchanges which had previously been established, 

 and through Professors Redtenbacher, Steenstrup, Kaup, 

 Krauss, Fraas, and Mr. Thomas J. Moore, many valuable 

 acquisitions have been made by the Museum. In order to 

 simplify the exchanges somewhat, we have also had the 

 assistance of several dealers in Natural History specimens, 

 who have invariably made prompt returns to the Museum. 

 Mr. J. G. Salmin, of Hamburg, particularly, has secured for 

 us many of the more common species of European animals. 



In addition to the public museums, intercourse has not been 

 neglected with private individuals, in order that we might 

 participate in the results of their investigations, and colonial 

 museums, where the treasures accumulated during the first 

 scientific explorations of their respective countries have been 

 deposited, have answered our application for exchanges in the 

 most liberal manner. I mention particularly Mr. Layard, of 

 the South African Museum, Professor McCoy, Dr. Haast, 

 Henry Edwards, W. Theobald, Jr., Mr. Rigacci, the Marquis 

 de Folin, Professor MichekofT, Mr. Parreys, Mr. Elizalde, Count 

 de Kornis, Professors Geyenbaur, Capellini, Gastaldi, Marcus, 

 Blanchet, Chavannes, and many others. 



The Museum is also indebted to private individuals for the 

 acquisition of valuable collections, the expenses of which were 

 principally defrayed by the Gray Fund. Among these are the 

 collections made by Professor Marcou, in the United States. 

 Mr. Rich has been engaged in obtaining specimens for the 

 Jardin des Plantes, as well as completing the collection of our 

 common wild animals. Mr. A. Garret has sent a valuable 

 collection from the Society Islands, collected with the greatest 

 care. Mr. Cooke has continued to send specimens from Zanzi- 

 bar. Mr. Anthony has also examined many collections in the 

 Northern States, with a view to supplying the deficienccs of 

 the Museum. Captain N. E. Atwood has rendered great 

 assistance in procuring Fishes from Provincetown. During 

 the vacations the students of the Museum have generally col- 

 lected largely while engaged in explorations in the fields, and 

 I must mention particularly the extensive collection of fossils 

 made in the West by Mr. 0. St. John, especially in Indiana 

 and Ohio. The collections made in Nova Scotia by Mr. C. F.
