pieces of the kSmithfield, Seelasgen, Thuncla, Coahuila, Canon Diablo, 

 Trenton, JNejed, Santa Rosa, Descubridora, Roeburne, Youndegin, 

 Miikerop, Arispe, and Costilla Peak irons, and Estacado stone, as 

 well as a quantity of fragments of the Bjurbole and Ochansk stones. 



Tliirteen additional accessions of meteorites, mostly new to the 

 collections, are recorded, received chiefly through exchanges, although 

 two purchases, three gifts, and one transfer are included. Among 

 the iron meteorites especial mention may be made of the peculiar 

 dumb-bell shaped mass from Savannah, Tennessee, an etched surface 

 of which shows evidence of fracturing and recementing, received 

 from the State Geological Survey of Tennessee as an exchange; a 

 smaller mass from Somerset County, Pennsylvania, showing faulting, 

 received as a gift through R. W. Stone, Assistant State Geologist of 

 Pennsylvania; and a small, complete, but very much oxidized and 

 irregular form found by Dr. J. W. Fewkes of the Bureau of Eth- 

 nology in the ruin of the Pipe Shrine House, in the Mesa Verde 

 ISational Park. A 320-gram piece of an iron from McDowell County, 

 iSiorth Carolina, was donated by the North Carolina State Museum, 

 and examples of two stones, one Garraf and the other Molina, 

 Spain, were acquired by exchanges, the former from the Museum 

 National d'Histoire Naturelle, Paris, France, and the latter from 

 Prof. C. Wendler, Chene-Bourg, near Geneva, Switzerland. By pur- 

 chase were obtained a mass weighing 15 J pounds (6.93 kilogr.) of 

 meteoric iron from Glasgow, Barren Co.,Ky.,and a fragment weigh- 

 ing 810 grams of an iron from Dungannon, Scott Co., Va. Other 

 accessions, while of value for study purposes, need no special 

 mention. 



A remarkabl}^ fine septarian nodule from Milam, West Virginia, 

 was purchased, and five slabs of marble, 24 by 59 inches, including 

 York Fossil, Westfield Green, Sonora, Napoleon Gray, and Welling- 

 ton Cream, were donated by the Tompkins-Kiel Marble Company, 

 New York City, for exhibition purposes. 



Through the continued activities of Victor C. Heikes of the U. S. 

 Geological Survey, located at Salt Lake City, have been acquired 

 some of the most interesting of the recent additions to the economic 

 collections. Groups of large, etched cubic crystals of fluorite, of deli- 

 cate purple color, from the Wildcat Mountains, Tooele County, Utah, 

 are the first representatives of this material from that state. The 

 material is not of optical quality, but closely resembles that from well 

 known localities in the upper Mississippi Valley. From the Tintic 

 Standard Mining Company, Dividend, Utah, he secured examples of 

 a remarkably pure massive ash-gray anglesite, showmg a peculiar 

 diffusion banded structure and containing ramifying cavities filled 

 with an unusual new silver mineral to which the name argento-
