though it is very difficult to form without these illustrations a cor- 
rect idea of the appearance and structure of this meteorite, we will give 
the following abstracts 
It was found in 1854 on the right bank of the river Volga in the 
steppes of the Kalmucs, 30 miles (German) from Sarepta in the district of 
Zarizin, - Saratow in Russia. Its original weight was 32lbs. 58 —

It is a compact iron mass, pretty rich in nickel, rounded at the edges, 
and entirely free from olivine or any dhe oreign substances. The gh 
repta meteorite is one of the most remarkable and peculiar known; a 
most characteristic difference, distinguishing its two sides, can readily ‘be 
again ed. The front side has the form of a genty sloping arch, similar

m all these data there seems to be no doubt that the position here

siaeene iron aes not appear to have been very long exposed to 
the atmospheric influences, its surface being hard!y acted upon by rust. 
It presents in its structure many analogies with that of Arva. The 
schreibersite in the figures upon the plates of the Sarepta iron does not 
show any interruption in its direction, although it does not penetrate them 
uniformly. The meteoric iron immediately adjoining the schreibersite 
shows distinctly fine characteristic strie and hatchings, most plainly in 
the darkest portio ;
