after the plan of Burden's, of two double cones, one hundred feet 

 long, with the engine between them, which with the boiler presents 

 some improvements. 



M. Cave, a mechanical engineer, has also constructed a double 

 boat, for the navigation of the canal of Somme. It differs from the 

 preceding in being open at the surface covered with a flooring and 

 has two keels and two helms. 



A similar boat has been constructed for the navigation of the 

 Loire, between Nantes and Anders. — Bui. Soc. Enc. rind. Nat. 





19. Meteorites. (O. P. H.)— On the 8th of June, 1834, a stone 

 fell at Charwallas, a village twenty three coss. (thirty nine three 

 fourth miles) west of Hissar, near Delhi, Hindoostan. At about 8 

 o'clock in the morning, the sky was cloudy, and the weather gusty, 

 or approaching to a north wester, but no rain, — very loud thunder, 

 similar to constant discharges of heavy artillery was heard for about 

 half an hour before it fell, and in the direction with the wind, to a 

 great distance. When the stone fell, it was accompanied by a trem- 

 bling noise, similar to a running fire of guns. It fell in the jungle 

 close to a pelec or herdsman, who was out with his cattle. The 

 original weight of the stone was twelve seers — but it was broken in- 

 to fragments by visitors, and scattered. It bore the usual external 

 appearances of meteoric stones. Sp. gr. 3.6, and affects a mag-

20. Fall of a Meteorite in Moravia. (O. P. H.) — x\t a quarter 

 past six, P. M., on the 25th of Nov., 1833, M. Reichenbach wit- 

 nessed the fall of a meteoric stone, accompanied by a brilliant light, 

 and a noise like thunder, in the neighborhood of Blansko, in Mora-: 

 via. The county was woody, and the larger mass could not there- 

 fore be discovered ; but he succeeded in finding some fragments, 

 weighing about half a pound, which resemble the stones that fell at 

 Benares, L'Aigle, Berlongville, fcc, so closely, that they cannot be 

 distinguished from them. According to Berzelius, in one hundred 

 parts, there are 17.15 of meteoric iron, separable by the magnet, 

 containing small quantities of nickel, cobalt, tin, copper, sulphur and 

 phosphorus — 42.67 silicate of magnesia and protoxide of iron, in 

 which the silica and base contain equal quantities of oxygen, to- 

 gether with some sulphuret of iron — 39.43 silicate of magnesia and
