56 REPORT OF NATIONAL MUSEUM, 1918. 



Through the interest of Mr. Victor C. Heikes and Mr. F. L. Hess, 

 a specimen showing crystals of tetrahedrite embedded in quartz, 

 from Park City, Utah, and one of galena with crystals of anglesite, 

 from the Eagle and Blue Bell Mine, Tintic District, Utah, were 

 presented by Mr. W. A. Wilson and Mr. W. H. Parker, Salt Lake 

 City, respectively. 



The collections were further enriched by the purchase of 72 cut 

 and polished gem stones of variscite, IT opalized shells from the Cre- 

 taceous of South Australia ; a large galena crystal from Illinois and 

 beryl from Siberia ; an unusually large cluster of milky quartz crys- 

 tals, four crystals of selenite, and two large pyrites. 



By exchanges, 11 specimens of minerals were obtained from 

 Ward's Natural Science Establishment, and four from the Public 

 Museum of the City of Milwaukee. These were principally from 

 foreign localities and represented species or varieties not previously 

 contained in the collections. 



Four types of minerals were presented by Dr. Henry S. Wash- 

 ington, Geophysical Laboratory, Washington City; 20 from Cali- 

 fornia, representing material described by the donor, Prof. A. S. 

 Eakle, University of California, Berkeley, California; and a col- 

 lection of 25 or more specimens, largely described material, by Dr. 

 W. F. Hillebrand, Bureau of Standards, Washington. 



Through Dr. W. T. Lee, of the United States Geological Survey, 

 22 specimens of aragonite crystals, from Amarillo, Texas, were given 

 by Mr. G. D. Bowie of that city. 



About 200 pounds each of amblygonite and spodumene, to be used 

 largely in the preparation of school collections, and a number of in- 

 teresting minerals from near Keystone, South Dakota, were collected 

 for the Museum by Dr. Edgar T. Wherry. 



A miscellaneous collection was transferred from the United States 

 Naval Academy, Annapolis, Maryland, late in the fiscal year. As 

 this has not been unpacked, nothing can be said as yet as to its value. 



In petrology but one described set was transferred by the United 

 States Geological Survey within the year — that illustrating the geol- 

 ogy and ore deposits of the Tintic District, Utah, to be published 

 as a Professional Paper (107) of the Survey, by Prof. Waldemar 

 Lindgren and Dr. G. F. Loughlin. An interesting series of rocks, 

 collected in the Orient by Dr. J. P. Iddings in 1910, and held by him 

 for study since that time, has now been formalty turned over to the 

 division. 



Owing to the fact that the division was without a head from the 

 resignation of the assistant curator last autumn to the end of the 

 fiscal year, practically no advance work was done on the reserve and 

 duplicate collections.
