Abstract
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.
