GEOLOGY AND MINERALOGY. 



Andersen, Olaf. Aventurine labra- 

 dorite from California. 



Amer. Mineralogist, 2, 

 No. 7, July, 1917, 

 p. 91. 

 Describes material in the 

 Museum mineral collection from 

 Modoc County, Cal., considered 

 unusual in owing its aventurine 

 character to inclusions of me- 

 tallic copper. 

 Beard, R. E. (See under Thomas L. 



Watson. ) 

 Brown, Glen V. The composition of 

 seleniferous sulfur. 



Amer. Mineralogist, 2, 

 No. 9, Sept., 1917, 

 pp. 116, 117. 

 Establishes by analyses of a 

 number of specimens the ap- 

 propriateness of regarding the 

 previously called selensulfur as 

 a variety rather than a species, 

 and suggests calling it selenif- 

 erous sulfur. The work is 

 based partly on Museum ma- 

 terial. 



Eakle, Arthur S. Minerals associ- 

 ated with the crystalline limestone 

 at Crestmore, Riverside County, Cal. 

 Univ. California Pub., 

 Bull. Dep. Geol., 10, 

 No. 19, Oct. 17, 

 1917, pp. 327-360, 

 pis. 21-24. 

 Upwards of 50 minerals from 

 an isolated mass of granodio- 

 rite with a capping of crystal- 

 line limestone at Crestmore, 

 Riverside County, Cal., are here 

 described, including two new 

 species, crestmoreite and river- 

 sideite. Many analyses are 

 given and a photograph of the 

 district appended. Much of the 

 determinative work in connec- 

 tion with this paper was done 

 in the chemical laboratory in 

 the National Museum during 

 the winter of 1916-17, and 

 fragments of a number of the 

 described specimens are in the 

 Museum's collection.
