1867.] 177 [Annual Report. 



Hayden in the " Mauvaises Terres " of Nebraska, fomiecT the 

 most vakiable accession ; they consisted principally of re- 

 mains of turtles and skulls of mammals; for the identifica- 

 tion of the species we are indebted to the kindness of Dr. 

 Leidy. The department is under obligations to the Acad- 

 emy of Natural Sciences of Philadelphia, as well as to the 

 following persons for donations : Drs. C. T. Jackson, F. V. Hay- 

 den, H. C. Perkins, and J. Wyman, and Messrs. C. G. Bush, 

 H. Davis, B. F. Mudge, S. H. Scudder, James G. Swan and 

 JosejDh Wagner. 



The department of Geology has been recently separated, 

 as in former times, from the department of Palseontology ; 

 a room has been furnished, and preparations made for ex- 

 hibiting specimens of rocks, building stones, models of sur- 

 face geology, and whatever may tend to illustrate the depart- 

 ment. This room will soon be opened, but series of owv 

 most common rocks are still much needed. A large geo- 

 logical map of this and the neighboring States, geological 

 sections, models of mines or of strata, views and photographs 

 of scenery exhibiting remarkable geological formations are 

 most desirable. Printed circulars have been sent to all the 

 principal quarries of Vermont, and to the architects and stone 

 dealers in this city, inviting donations of sj^ecimens of build- 

 ing stone. A valuable gift has been received from the Cura- 

 tor, in the large collection of volcanic minerals, made by 

 himself, in 1864-5, in the Hawaiian Islands. It comprises 

 many hundred specimens, and forms the most complete 

 collection of the kind ever brought from that locality. It 

 has been recently unpacked and, in great part, labelled and 

 arranged for exhibition. The collection has received dona- 

 tions from Drs. A. C. Garratt and F. V. Playden, and from 

 Messrs. H. A. Lawrence, F. G. Sanborn and G. B. Towle. 



The condition of the Mincralogical cabinet is very good ; 

 the specimens are all labelled and well arranged for exhibi- 

 tion. Considerable work has been expended upon them by 

 the Curator, and small but valuable donations of ores and 

 other minerals have been received from Drs. C. T. Jackson,
