. On the Meteorite of Mamboum, Bengal ; Mr. Haip1ncEr.— 
ms meteorite fell 130 miles acithead of pach on the 22d of De- 
a nut, near : 
base of the stone is ash-gray and is distinctly brecciform in structure, 
without rounded granules. Monosulphuret of iron is abundant in it, 
theugh only in minute particles; grains of metallic iron are less numer- 
ous. The spi gravity is 3-424.—Ber. Wien. Ak kad., Sept. 21, 1864. 
ew Asteroid.—Another small planet was discovered April 26th 
by d e Ganjaes at Naples. It was equal in brightness to a star of the 
10th magnitude.

pressure at the outer extremity. The wena Sci soda the 
author daoate furrows or fractures of a similar kind, and in ases 
the material was divided into small separate lamell. The evenly bean 
structure of the cylinder of ice shows that the origin of these fractures is 
subsequent to the first formation of the cylinder. 
For a block of the dimensions employed i in the experiments the pres- 
sure required for the flow of the ice is 10,000 ep reign while for lead 
it is 50,000 kilograms, These pressures correspond, for the square centi-
