REPORT OF NATIONAL MUSEUM, 1921. 83 
precious opal from Nevada, a suite of rare sulphosalts from the Bin- 
nenthal, Switzerland, and miscellaneous minerals, chiefly from for- 
eign sources, were obtained through exchange with Ward’s Natural 
Science Establishment. In a lke manner were added a number of 
Italian minerals, received from Prof. Alberto Pelloux, Genoa; mis- 
cellaneous minerals from California, including some rare sulphates 
and an attractive exhibition specimen of beautifully crystallized 
pink halite from Searles Lake, received from Mr. M. Vonsen, Peta- 
luma, Calif.; interesting lead and vanadium minerals sent by Mr. 
C. A. Heberlein, Supai, Ariz.; and a collection of the unusual zeo- 
lites from North Table Mountain, near Golden, Colo., received from 
the School of Mines at Golden. 
The Rainbow Ridge Mining Co., through Mr. Archie Rice, New 
York City, presented a suite of precious opal from their mines in 
Humboldt County, Nev. These show the variations in the coloring 
of the opal, ranging from the very dark or “black” opal to the 
palest opalescent tints. .The collection forms a part of an exhibit 
composed entirely of opals in the matrix. 
Additional accessions of note include the following gifts: Rare 
copper minerals from Chuquicamata, Chile, presented by Guggen- 
heim Bros., New York City; exceptional specimens of wolframite, 
by J. F. Aguilar Revoredo, Oruro, Bolivia, and of the rare mineral 
hewettite, by A. O. Egbert, Prescott, Ariz.; sphenomanganite and 
catoptrite from Sweden, new to the collections, by Col. W. A. Roe- 
bling, Trenton, N. J.; inyoite from New Brunswick, by E. J. Arm- 
strong, Erie, Pa.; a large specimen of bismuthinite, by W. H. Wey- 
her, Alta, Utah, and an exceptional specimen of sphalerite, by C. H. 
Short, Salt Lake City, both obtained through the efforts of Mr. Vic- 
tor C. Heikes; a large group of fluorspar crystals, by the Diamond 
Fluorspar Co., Karbers Ridge, Ill.; described specimens of augite 
and apthitalite, by Dr. Henry S. Washington; and several examples 
of semiprecious stones, by F. M. Myrick, Johannesburg, Calif. 
A most important addition to the collection of gems and gem 
minerals was afforded by the acquisition, through the Frances Lea 
Chamberlain fund, of 56 cut and uncut tourmalines from Mesa 
Grande, Calif. The cut forms include both cabochons and facetted 
stones and show the rich variety of coloring characteristic of this 
mineral; the crystals are of varying sizes, showing two to three 
colors in each example. Through the same means were secured 9 
cabochons of chrysoprase; 6 blue zircons from: Queensland, Aus- 
tralia; 4 carved jades; 2 cabochons of Persian turquoise; 2 cut gems 
each of Madagascar orthoclase and wernerite; 1 Australian opal 
carved in the form of a pansy blossom; 4 blue and yellow Australian 
sapphires; and an Australian opal, cut cabochon, weighing 31.9
