Report on the ShalJca, Sfc. Meteorites. 
proportion, are spread through the darker and lighter stony sub- 
stances. As in other meteorites of the same category, iron particles 
accumulate occasionally around the included globules, as in some 
amygdaloid rocks, green earth (decomposed angite) accumulates 
around the included minerals, or in the cavities left after their decom- 
position. It may he inferred from this remarkable fact, that during 
the gradual solidification of the meteorite when the globules were 
already included in the fundamental substance, the iron particles, dis- 
persed in it, underwent a change of place. Similar phenomena ob- 
servable in our terrestrial rocks may he conveniently explained by 
supposing the existence of subterranean solvents, either water, or 
compounds of chlorine, fluor, and sulphur, assisted in greater depths 
by the increasing internal heat. With reference to meteorites, it may 
he sufficient here to state this curious fact, recommending it earnest- 
ly to further investigation. 
The crust is dark greyish-black, in some places with a slight indi- 
cation of beginning brightness ; and very thin. No indication of 
the direction followed by the stone in its flight, or its downfall is to 
* 
be found on it, as we have before us but a fragment, although pro- 
bably the most considerable, of an entire stone. The portions, how- 
ever, probably answering to the anterior and posterior sides of the 
stone, bear rounded shallow impressions. Specific weight at a tem- 
perature of 17° B. = 3.792. 
The specimen kindly transmitted by the Asiatic Society of Bengal 
has been cut into two pieces of 4 oz. and lfoz., ready to be delivered 
to the Imperial Museum. Both these specimens shew more of the 
crust than of the interior substance, and are perfectly polished on a 
surface of about two square inches.

No specimens of this meteorite have hitherto found their way to 
Europe, nor is it mentioned, either in Mr. Greg's accurate essay 
(with MSS. supplements from the author to June 1S59) nor in Prof. 
Shepard’s index, (continued in MS. to November 1859) nor in Dr. 0. 
Buchover’s book on igneous meteors 1859, nor in any other European 
book or periodical. The only notices at present known, exist in the 
Journal of the Asiatic Society of Bengal (Vol. NXI1I. p. 736, 1354 
— Vol. XXIY. p. 247, 1855— and Vol. XXV. p. 169, 1856.) The
