REPORT OF NATIONAL MUSEUM, 1914. 117 



paleontolog}^, 11,041; vertebrate paleontology, 1,130; and paleo- 

 botany, 571. There were also received for examination and report 

 546 lots of specimens, of which 217 were geological, 280 mineralogical, 

 and 49 fossils, and it is interesting to note that in the material sent 

 for this purpose there has been a great increase in the proportional 

 amount supposed to contain radioactive minerals. While the Mu- 

 seum has not the means for making detailed analyses of specimens, 

 simple determinations are generally sufficient to decide their nature 

 and general value and of all of the specimens received in this con- 

 nection during last year only 27 were of any interest either to science 

 or to the Museum. 



Systematic and ayflied geology. — The Koyal Ontario Museiun of 

 Mineralogy, of Toronto, Canada, transmitted as an exchange a series 

 of rocks and ores illustrating the geology and petrology of the Sud- 

 bury nickel region and the Cobalt mining district, including some 

 exceptionally good exhibition examples of native silver in gangue 

 and of nickel-cobalt minerals. The American Vanadium Co., of 

 Pittsburgh, Pa., presented a suite of the recently described Peruvian 

 minerals quisqueite, patronite, and other forms. A gift from the 

 Mason Valley Mines Co., of Mason, Nev., through Mr. Victor C. 

 Heikes, consisted of a large specimen of native copper, weighing 

 some 200 pounds and forming an attractive addition to the recently 

 installed exhibition of this metal. Two sections of the trunk of a 

 fossil tree impregnated with carnotite, quite unusual in character 

 and important for display, were obtained from Grand Junction, 

 Colo., by purchase. Also worthy of mention are the following gifts : 

 From Mr. Charles H. Hussey, Mr. M. S. Duffield, and Mr. F. L. 

 Woods, of Ogden, Utah, a piece of a 6-inch quartz vein, weighing 

 over 100 pounds and containing an abundant development of blade- 

 like crystals of tungsten ore; and from the Maine Feldspar Co., of 

 Brunswick, Me., large specimens of pegmatite well illustrating the 

 phenomenon of graphic intergrowth of quartz and feldspar, and 

 many hand specimens of feldspar of the grade used in the manu- 

 facture of pottery. 



Among the additions to the building stone exhibit were a slab of 

 dark Mohegan granite, measuring 32 by 32 by 3 inches thick, and 

 two 5-inch cubes, from Peekskill, N. Y., presented by the Mohegan 

 Granite Co. ; and two large slabs, measuring 78 by 20 inches, of " Mar 

 Villa " marble from the quarries of the Beaver Dam Marble Co., at 

 Cockeysville, Md. A number of slabs of marbles which had been 

 submitted in connection with the competition for the Lincoln 

 Memorial in Washington were contributed by the Amicalola Marble 

 Co., of Ball Ground, Ga. ; the Lee Marble Works, of Lee, Mass. ; Wm. 

 Bradley & Son, of Long Island City, N. Y.; the Colorado Yule
