The quantity was far too small to encourage a search for cobalt and other metals. 
Besides the nickeliferous iron, which is disseminated very sparsely, and in particles 
singularly unequal as regards their size and distribution, and with which troilite is asso- 
ciated in very small quantity, chromite is present as a constituent of small but appre- 
ciable amount. 
The crystals of this mineral are distinct, and sometimes present minute brilliant faces 
and good angles for measurement. One of these gave the solid angle of a regular 
octahedron. 
XI. On the Mane gaum Meteorite of 1843. 
Of the circumstances attending the fall of the Manegaum meteorite, and of its ap- 
pearance as seen in section in the microscope, I gave some account in the Philosophical 
Magazine of 1863. 
I was precluded at that time from making chemical analyses at the British Museum, 
and was unable to investigate with any precision the nature of this stone, which is one 
of those that, in the well-defined character of a chief ingredient, offers considerable 
advantages for the inquiry on which I am engaged. 
The meteorite fell on the 29th of June*, 1843, at Manegaum in Khandeish, at half 
past three o’clock p.m. A very small part of it was preserved ; and of this a little fragment 
was sent to the British Museum, as one among many valuable contributions of the kind 
from the Asiatic Society of Bengal. 
* The date usually assigned to this fall, viz. the 16th of July, is erroneous. The true day of the fall is given, 
in the Mahratta account of it, as the third day of the month Asarh sudi, on Thui'sday. I am indebted to General 
Cunnivguaji for the identification of this date with the 29th of June, 1843. [For the account see Journal As. 
Soc. Bengal, vol. xiii. p. 880.]
