Abstract
The area, the geological features of which it is purposed to attempt a description of, so far as known, comprises peninsular India from Bombay on the west, and Ganjam on the east coast, to Cape Comorin, lying between the 8th and 20th degrees of north latitude. Its northern limit is skirted by the Sub-Vindhyan ranges, and the plains of Central India; while the remaining sides are washed by the ocean, and lie within the 72nd and 86th degrees of east longitude.
