18 Notice of Prof. Clark’s Thesis on Metallic Meteorites. 
Rammelsberg infers from his analysis that the pyrites is a 
simple sulphuret, Fe 8. Its composition is, 
Sulphur, - - - - 28°155 
Tron, - - - - 65°816 
Nickel, - - - - 1-371 
Cobalt, - - - - 1371

The insoluble portion after the separation of the silica and 
carbon, contains, according to Rammelsberg,

27, Hauptmannsdorf, near Braunau in Bohemia. Fell July 
14th, 1847. Described by Beinert in 1847. At break of day, 
the inhabitants of Braunau and vicinity were startled by a vio-’ 
lent, roaring sound, which continued for some minutes. A small, 
black cloud was observed over the village, which suddenly 
glowed as if on fire, and sent out flashes of light in all direction. 
Two fireballs fell from the cloud attended by two explosions, 
like the report of cannon. It having been reported that lightning 
had struck in a neighboring field, the place was visited, and a 
metallic mass found, which had buried itself to the depth of three 
feet in the earth, and which six hours after the fall was so warm, 
that it was impossible to bear the hand upon it. It was subse-

nau had been struck, and that another fragment of the meteor 
had broken through the roof, passed through the chamber in 
which persons were sleeping and buried itself in the side of the 
house. ‘The larger mass weighed 42 lbs. 3 oz. (Austrian), the 
smaller, 30 lbs. 8 oz. The former was cut up for furnishing spe- 
cimens to cabinets, the latter is still entire, and in the possession 
of the abbot of the monastery of Braunau. he larger fragment 
had the form of an irregular rhomboid; while the smaller re- 
sembles a huge oyster shell. Both were covered with more or 
less regular hexagonal concavities. ‘The color is iron-gray, 
in the concavities, reddish brown, from a small quantity of me-
