76 EEPORT OF NATIONAL MUSEUM, 1922. 



Other gifts to be noted are a series of iron carbonate (sphaerosid- 

 erite) and associated minerals from vesicles in the basalt of Co- 

 lumbia Eiver at Spokane, Wash., presented by Henry Fair, Spokane; 

 examples of the diamond-bearing rock from the Ozark Diamond 

 Mine, Pike County, Ark., received from Austin Q. Millar, Murfrees- 

 boro, Ark. ; and a fragment from a mass of metallic zinc from Lin- 

 chow, China, donated by Dr. J. Morgan Clements, is interesting his- 

 torically as dating back to the Ming dynasty. It is reported that 

 GOO piculs (over 80,000 pounds) of this metal, found buried in a cave, 

 were sent to England in 1916. 



Type collections from Round Mountain, Nev., and the Tintic 

 district, Utah, illustrating publications of the United States Geolog- 

 ical Survey, and a series of volcanic products showing some of the 

 phenomena connected with the recent eruptions of Lassen Peak, 

 Calif., as observed by Dr. J. S. Diller, of the survey staff, are the 

 chief materials transferred by that organization. 



Asbestiform crocidolite, amosite, and chrysotile — materials now 

 being commercially utilized and of value for study and comparison — - 

 were received by exchange with the Geological Survey, Pretoria, 

 Union of South Africa, and an interesting series illustrating the 

 mode of weathering of a dense, acid, porphyritic rock, was collected 

 by the head curator from Mount Kineo, Moosehead Lake, Me. 



The most notable addition to the meteorite collection is the magni- 

 ficent mass of iron from Owens Valley, Calif., gift of Lincoln Ells- 

 worth, New York City, and referred to in my last report. It will be 

 recalled that this iron, as found, weighed 475 pounds and that from 

 it was cut a portion weighing 78 pounds, which Mr. Ellsworth re- 

 tained for his own cabinet, generously donating to the national col- 

 lections the larger portion together with the ebony base upon which 

 it rests. A number of examples of falls and finds either new to the 

 collection or hitherto poorly represented were acquired by exchanges. 

 From the Museum d'Histoire Naturelle, Paris, were obtained ex- 

 amples of the rare iron-rich olivine stone that fell in 1815 in Chas- 

 signy, France, and the black chondrite of Sevrukovo, Russia; from 

 Ward's Natural Science Establishment, samples of the Rosario, Hon- 

 duras, and Arlington, Minn., irons and the stone of Chantonnay, 

 France; from Prof. Arthur B. Bibbins, an irregular slice of the iron 

 from Odessa, Ector County, Tex. ; and from Prof. Donald W. Davis, 

 an oval section of a stone from Sharps, Richmond County, Va. Also 

 by exchanges were acquired a complete individual of the Toluca iron, 

 weighing 1,495 grams, sent hj the National Museum of Mexico, and 

 a 48-gram slice of the Chmautla, Guatemala, iron, from Col. Wash- 

 ington A. Roebling. Approximately 320 grams of a pallasite, found 

 in June, 1921, near Cold Bay on the Alaskan Peninsula, and acquired
