Página 280 - On the southward side they rise abruptly from the extensive plain of Berar, the average height of which is one thousand feet above the level of the sea, and tower above it to the height of two and three thousand feet. The descent to the bed of the Tapti is equally rapid, although the northern is less elevated than the southern side of the range. The outline of the land is generally flat, but much broken by ravines and by groupes of flattened summits, and isolated conoidal frustra. The summitsand...

Mr. Murray had previously told us, that " when a stick of excited sealing-wax is brought near the thread of suspension, it is evidently repelled ; consequently, the electricity of the thread is of a negative character," while " an excited glass tube brought uear, seemed to attract the thread, and with it, the aeronautic spiderf.
Página 460 - In Derbyshire the beds of metalliferous limestone, are separated by beds of basaltic rock called toadstone*. When a vein of lead is worked through the first limestone down to the toadstone, it ceases to contain any ore, and often entirely disappears : on sinking through the toadstone to the second limestone, the ore is found again, but is cut off by a lower bed of toadstone, under which it appears again in the third limestone. In strong veins, particles of lead occur in the toadstone, but in very...
Página 280 - Wernerian would not hesitate in pronouncing them to be of the " newest floctz-trap formation," aHuttonian would call them " overlying rocks, "and a modern geologist would pronounce, that they owed their origin to sub-marine volcanoes. I shall not give them any other name, than the general one of trap-rocks ; but proceed to describe them, and state with diffidence the inferences which, I think, obviously present themselves on an attentive study of their phenomena.

When a .conductor is brought near the thread by which it suspends itself, but, above all, to the flocculi or balls, they are considerably deflected from the perpendicular, and the horizontal fibre is attracted by the point : when a stick of excited sealing-wax was brought near the thread of suspension, it seemed to be repelled;...
