. Edinburgh New Philosophical Journal . upper mounds a and b, Fig. 4, have this shape. Sometimes the two extremities are high, and the middle low; but in passing over the ground, it is easy to discover that since the materials were deposited, the surface has been much altered by the de- nuding action of the river itself, and the various streamlets which flow down from the western ridge after heavy rains. No section can give a correct idea of the whole deposit; and as one along the middle must have been to a great extent ima- ginary, I have thought it my best course to sketch in Fig. 4, Fig. 4.
