Orthoclase as Gangite Mineral in a fissure Vein. By Waldemak 
LiNDGREN. {Am. J. Sci., isj, ^18-420.) 
After noting the rather sparing occurrence of the feldspars in true 
veins, the author describes a silver-gold vein near Silver City, Idaho, 
having a gangue of tjuartz and orthoclase. The orthoclase is of the 
variety adularia, and the evidence of its aqueous origin is followed by 
an analysis yielding SiO^, 66.28; Al-.Os, 17.93; K-O, 15.12; Na,0, 0.25; 
undet., 0.42; total, 100.00. vv. o. c. 
Notes on Rocks 'a)id Minerals ftoni California. By H. W. Turnek. 
(Atn. J. Set., /js, ^21-428.) 
This paper describes: i. a peculiar quartz-amphibole dioryte, with 
very complete analysis of the dioryte and its component amphibole; 
2. a new amphibole-pyroxene rock from Mariposa county; 3. a quartz- 
alunite, with an analysis of the alunite, which occurs as an efflores- 
cence; 4, zircon from gravels; 5, molybdenite from several localkties; 
6, tellurium, selenium and nickel in gold ores; 7. carboriaceous ma- 
terial in quartz from gold veins east of the Mother lode; 8. berthierite 
from Tuolumne county. w. o. c. 
Mineralogical Notes on AntJiophyllite, Enstatite and Beryl {Emerald] 
from North Carolina. By J. H. Pratt. {Am. J. Set., /jj, 42Q-4J2.) 
The anthophyllite and enstatite are from the great dunyte dikes of 
Western North Carolina ; and two analyses of each are given. The 
emerald is from vein of pegmatyte in Mitchell county, and was not 
analyzed. • w. o. c. 
The Jerome {Kansas) Meteorite. By Henry S. Washington. {.Im. 
J. Sei., 133, 4-t7-454-) 
This meteorite, about 65 pounds in weight, is a deeply oxidized 
mass, made up of numerous chondrules of bronzite and olivine, with 
fragmental crystals of these minerals and pyroxene, and small angu- 
lar masses of nickel-iron (4.3 per cent.). No troilite was recognized, 
but the analysis indicates that it was originally present to the extent 
of 5.2 per cent. An approximate chemical analysis and an analysis of 
the nickel iron, which contains 10.01 per cent, of nickel, are followed 
by exhaustive analyses of both the soluble and insoluble portions; and 
from these analytic data the mineralogical composition is calculated, 
the chief constituents, in order of abundance, being olivine, bronzite. 
limonite (secondary), oligoclase, troilite, pyroxene, nickel-iron and 
orthoclase. w. o. c 
On the Origin of the Corundum associated luith the Peridotytes in 
North Carolina. By J. H. Prati'. {Am. J. Sei., 136, ./g-6j.} 
The peridotyte (dunyte or olivine rock) is a basic, magnesian, plu- 
tonic rock forming lenticular dikes and bosses in gneiss, and the 
corundum is invariably found on tlir borders of these masses, between
