Abstract
It would appear that, in order to explain all the phænomena of the denudation and the post-tertiary or pleistocene accumulations of the district, it is necessary to suppose the following vertical movements of the land:— A first elevation ; dating, perhaps, as far back as the commencement of the Tertiary epoch, during which the more marked physical features were produced, accompanied with an enormous destruction of Secondary rocks. This was followed by a submersion , which appears to have been only partial, during which the Northern Drift, with ice-transported boulders, was spread over the area under water. Next, a second elevation ; towards the close of which the estuarine mammaliferous gravels were formed along the valleys, and round the flanks of the hills. During this latter elevation the relative positions of land and sea occurred which have been described above, the period finally terminating with the introduction of the present physical features of the country.
