the fragment preserved in the collection of the Asiatic Society 

 of Bengal, and was included among the specimens presented 

 to the Museum by that Society. 



The crust is very black and dull in lustre ; it is thick and 

 somewhat foliated. The portion retained by the Society exhibits 

 this crust on three of its sides. 



The ground-mass of this aerolite consists of a nearly white 

 mineral highly charged with spherules of greenish-yellow olivine 

 (the waxy mineral) , in some cases very dark in hue, and pre- 

 senting under the microscope the characteristics of that mineral 

 as exhibited in other aerolites. 



It is not sufficiently compact to take a polish. 



There is less iron apparent than is the case in Nellore, though 

 more than in Durala ; and it is in rather large grains. 



The meteorite is somewhat stained by patches of rust round 

 the iron granules ; the result, no doubt, of its porous and loosely 

 aggregated character. 



There is a good deal of meteoric pyrites, somewhat crystalline 

 and generally in association with the iron. 



By reflected light in the microscope a white opake flocculent 

 mineral is seen in some little quantity, rarely clouding the other 

 minerals present as it does in Bishopville, Mallaigaum, &c, but 

 usually in fragments and small nodules (as in Borkut, Seres, and 

 some other aerolites) intermixed with the other materials of the 

 stone.

15. Mhow. 



The village of Mhow (or Mow) stands on the right bank of 

 the Tons, an arm of the Gogra. It is about 37 miles north of 

 Ghazeepiir, and 30 miles south-east of Azimqur, and 57 miles 

 south-east of Goruckpur, lat. 25° 54', long. 83° 37'. Five miles 

 from this village, at 3 o'clock in the day, on February 27, 1827, 

 an aerolitic shower fell from a serene sky. The largest stone 

 recorded weighed 3 lbs. Fragments were picked up four or five 

 miles apart, one of which broke a tree, and another wounded a 

 man. The fall was accompanied by noises like the roar of ord- 

 nance. 



The fragment preserved in the collection of the iVsiatic Society 

 at Calcutta weighed 12| ounces, and for a portion of that speci- 

 men the National Museum is indebted to the liberality of that 

 important Society. 



The specimen exhibited in the Museum weighs BJ ozs. The 

 original specimen, when entire, was of a peculiar form. Rudely 

 four-sided and somewhat pyramidal, it presented a curved shape, 

 so as to look like a fragment splintered from a shell or a hollow
