Extract

The remarkable conglomerate, called nagelflue, which fringes a considerable extent of the northern district of the Swiss Alps, and in places forms almost mountain masses rising some 5000 feet above the sea, has already received much attention from geologists. One might then fear to handle a subject almost as well worn as its pebbles. Still there are one or two points to which in the present state of our knowledge it may be worth while to call attention.

page 514 note 1 In some very valuable remarks made after the reading of this paper, Mr. W, T. Blanford, F.R.S., referred to a series of conglomerates (which he considered of Pliocene age) largely developed in the Upper Siwalik in the north-west of India, on the flanks of the Himalayas, and west of the Indus in the Punjab and Sind (described as he informs me by Mr. Medlicott in the Manual of Geology of India, vol. ii. pp. 466, 525, 532, 541, and 570). These he compared with the gravel slopes along the base of the Himalayas (vol. i. p. 403), expressing the opinion that all ofthem, with the nagelflue, were very probably the results of subaerial fluviatile action.
