REPORT OF NATIONAL MUSEUM, 1922. 77 



through S. R. Capps, of the United States Geological Survey, 

 represents the second meteorite thus far reported from the Territory. 

 By purchase were obtained examples of Bremervorde, Germany, 

 Nerft, Russia, and Toubil, Siberia, falls. 



Various dealers in building materials have donated samples of 

 their products in the form of 4-inch cubes or large slabs for wall 

 panels. These are the Beaver Dam Marble Co., Milford Pink- 

 Victoria White Granite Co., Presbrey-Leland Co. (Inc.), and Tomp- 

 kins-Kiel Co., the last named having been particularly generous. 



The study series of minerals has benefited materially through ex- 

 changes. First among these are minerals and rocks from Greenland, 

 valuable in that they are practically all examples of type minerals 

 described in Prof. O. B. Boggild's classic monograph on the minerals 

 of Greenland, from whom they were obtained. Unusual Italian 

 minerals, needed to fill gaps in the systematic series, were likewise 

 obtained from Prof. Alberto Pelloux, Genoa, Italy. Four specimens 

 of datolites from Westfield, Mass., including three type crystals 

 showing new forms, described by Earl V. Shannon, were secured by 

 exchange from Ward's Natural Science Establishment. 



Three important exhibition specimens are included among the 

 gifts of this year: (1) A large cluster of colemanite from Inyo 

 County, Calif., probably the finest thus far known, donated by W. S. 

 Russell, Los Angeles; (2) an unusually showy and attractive speci- 

 men of cuprite showing sharp, deep-red crystals on native copper, 

 from the Ray Consolidated Mines, Ariz., given by Dr. R. O. Hall, 

 San Jose, Calif.; and (3) a zoned rhodonite of unusual form, with 

 yellow axinite, from Franklin Furnace, N. J., gift of Col. Washing- 

 ton A. Roebling, Trenton. This last will become an object of special 

 research by Messrs. Larsen and Shannon. 



A collection, including ptilolite and associations of unusual interest, 

 was received as a gift from C. L. Kirtley, Challis, Idaho. These 

 are much larger and finer than those from any previously known 

 locality. Another gift, consisting of eight specimens of pucherite 

 from Brazil, is representative of the first occurrence of this rare 

 bismuth-vanadium mineral in crystallized form in America. The 

 material was presented by J. E. Carney, jr., through F. L. Hess. 



The various transfers from the United States Geological Survey 

 comprise chiefly type minerals, notably original or analyzed speci- 

 mens of brannerite, bementite, gillespite, and magnesioludwigite. 

 A section of mica from Spruce Pine, N. C, with an included garnet 

 crystal, received from the same source, is worthy of mention and 

 will be placed on exhibition. 



By purchase were obtained (1) a series showing the effect of 

 radium rays on the color of minerals, prepared by Prof. C. Doelter, 

 Vienna, Austria; (2) examples of nesquehonite, demantoid garnet,
