sian locality ; but at Magnet Cove the cubical form is exceptional in 
the magnetite crystals, that prevailing being the octahedron, with the 
faces of the cube more or less developed. 
Wavellite, from a new locality in Arkansas. It occurs not only on 
sandstone, but coating crystals of transparent quartz in small green 
radiations, closely resembling a prehnite. Limonite is associated with 
it, coating the quartz in the same way, and appears to be the result of 
alteration of the wavellite. The large and perfect spheres of the 
latter show a lighter color on fracture, which distinguish it from the 
form which is found in Montgomery County. 
Spherostilbite and chabazite, from Tyringham, Berkshire County, 
Mass. They are found in a vein of pyroxene, attached to mica. The 
chabazite is white, resembles very closely that of Aussig, Bohemia, 
and occurs in crystals from one-eighth to one-quarter of an inch in 
length, associated with spherostilbite. The latter is found in beauti- 
ful isolated spheres up to one-quarter of an inch in diameter, in one 
case coating a hexagonal crystal of dark gray mica, and rivals any 
found elsewhere in this country. Isolated crystals of the mineral are 
rare. 
Iron Garnet, from Russell, Mass. These crystals are remarkably 
well defined, of a dull brownish black color, usually trapehedrons with 
the faces of the rhombic dodecahedron slightly developed. They were 
found in a vein between coarsely crystallized mica and feldspar, with 
the interstices filled with quartz. They vary in size from one-quarter 
to three and one-quarter inches, and are found in beautiful groups 
which sometimes contain from fifty to one hundred and fifty perfect 
crystals. 
November 5, 1883. 
REGULAR BUSINESS MEETING. 
The President, Dr. J. S. NEWBERRY, in the Chair. 
Twenty-eight persons present. 
Dr. ANTONIO DI GREGORIO, of Havana, Cuba, was elected Cor- 
responding Member, and several of his published papers were 
presented to the Academy. 
Dr. B. N. Martin exhibited specimens of copper ore, from the 
vein recently opened at Bloomfield, N. J., one foot and a half in 
width, containing twenty-seven per cent. of copper, and crossing 
a bed of shale impregnated with copper. 
The PRESIDENT remarked that a large quantity of copper was 
ontained in the rocks of the Triassic formation, although no pay-
