Report on the Shallca, fyc. Meteorites. 
American Association for the advancement of Science (New Haven, 
August, 1850). The fall took place at 25° 57' North Latitude, and 
80° 50' E. Long. One of the stones had a weight of 22 lb. Professor 
Shepard saw in 1849, a stone of 2 lb. in possession of Mr. Thomas 
MacPherson Grant of Edinburgh, from whom he obtained a frag- 
ment of it. The learned Professor describes it, as being fine-grained, 
trachytoid, and resembling the meteorites of Poltawa (March 12th, 
1811) and of Cashin in Maine (May 20th, 1848), (See Silliman's 
American Journal, 11 Ser. Vol. XI. p. 367 . — Edinburgh Phil. Journal, 
Vol. VIII. October, 1852, p. 245. Poggendorff's Annalen ; Pogus- 
lawslcy's Zehenter Naclitrage &c., Supplement Vol. IV. p. 22, 1854). 
The fundamental substance of the Futtehpore meteorite is of a 
light-ash grey, fine-grained, with dispersed yellowish brown rust-like 
spots on the broken surfaces. Lamella; of iron pyrites run through 
the substance like as many miniature veins ; some of them being 
made visible by fracture ; they are reddish, brass yellow like magne- 
tic iron pyrites. When ground and polished, the surface shews 
numerous particles of metallic iron of different sizes ; the largest of 
them being 1)'" in length and 1'" in breadth. Crevices or fissures 
now filled up with solid matter,' intersecting each other under dis- 
tinct angles, run through the substance in various directions ; some 
capillary fissures are filled with the dark-coloured substance of the 
crust ; others of equal tenuity probably with metallic iron or mag- 
netic pyrites. These fissures run on the whole surface laid bare by 
cutting the stone through a length of above 2 inches ; and through 
the whole thickness of the stone. They shew intersections, junctions, 
derangements, just as metalliferous veins shew on an infinitely larger 
scale. Metallic particles have occasionally a section of 3"' in length. 
The abovemontioned rust-like spots appear on the sections, in 
an isolated situation, generally spreading along the sections of 
fissures or surrounding metallic particles. The substance in itself 
soft and friable, includes in some places larger or smaller globules 
made visible by section. One of these globules, about 1^" in 
diameter, greyish white, compact, includes laterally a small quantity 
of iron, surrounded witli a yellowish brown spot, not continuing into 
the surrounding soft substance, which, however, shews plenty of 
similar spots. Other globules, opaque when cut through, seem to be
