REPORT OF XATIOXAL MTTSEUM, 1920. 103 



ment, Eocliester, Xew York ; samples of three stones, Appley Bridge, 

 Mornans, and OjSji, from the British ^fusenm (Xatiiral History), 

 London; some 2,500 grams of fragmental material from the Bjiir- 

 bole, Finland, stone, from the Geological Commission of Finland: 

 and a fragment of the Port Orford, Oregon, pallasite, from the 

 Boston Society of Natural History. The last, while very small, 

 weighing but 25 grams, is interesting historically, having been taken 

 from a large mass some 5 feet in diameter in 1856 by Capt. John 

 Evans, a Government geologist, t\'hile making explorations in Ore- 

 gon, and supposed by him to be iron ore. Its meteoric nature was 

 determined by Dr. C. T. Jackson, and an unsuccessful attempt was 

 apparently made to locate it for the Smithsonian Institution, but 

 wdiich failed owing to the death of Captain Evans. The single 

 small specimen w-as lost to sight until some years ago when it w^as 

 located among the collections of the Boston Society of Natural His- 

 tory and has now been secured for the Museum, where it doubtless 

 should have come originally. With the help of Captain Evans's 

 original manuscript, it has been possible to locate with considerable 

 certainty the locality of the mountain from which it was obtained, 

 antl it is hoped that means will be found for undertaking an explora- 

 tion for this interesting object with the idea of securing the entire 

 mass for the Museum. 



The gem collection has received but few additions. Among these 

 are a bracelet of amber of peculiar color, purchased through the 

 Frances Lea Chamberlain fund; a series of garnets and peridots 

 in the rough from the Navajo Reservation, Arizona, presented 

 by Mr. Frank Springer; and several hundred small seed pearls 

 from Panama and five " fairy stones," gifts of Mr. H. P. Petersen. 



An excellent series of crystallized native copper and silver with 

 a number of miscellaneous minerals from the Lake Suj^erior region, 

 was acquired by purchase and gift from Mrs. James Merton, Chevy 

 Chase, District of Columbia. Other materials that need to be noted 

 on account of their unusual character or for having been made the 

 subject of special research include a sample of lead-bismuth ore 

 sent by Mr. Tim McCarthy-, Wickes, Montana, which proved to be 

 a new mineral described under the name hismutoplagionite by Mr. 

 Earl V. Shannon; sillimanite, variety- bucholzite, from Russell, and 

 gedrite from Chesterfield. Massachusetts, presented and described 

 by Mr. Shannon; laumontite from Lewis and Clark County. Mon- 

 tana, representing an unusual occurrence, presented by Mr. Charles 

 P. Farnquist, Spokane, Washington, and fragments representing 

 tlie first American occurrence of the mineral boussingaultite, from 

 California, gift of Charles W. Fletcher, Los Angeles, also de- 

 scribed by Mr. Shannon in association with Mr. E. S. Larsen. A 

 crystal of manganotantalite from Amelia, Virginia, gift of Mr.
