Leopold von buch, who in the beginning of this century travelled through Norway as far as the North Cape, was the first who wrote about the geology of the northern part of the country (Reise durch Norwegen und Lapland, Berlin, 1810). Some years later the natural conditions of the country were examined by Vargas Bedemar. On this voyage he went as far as Varanger, and has recorded the result of his inquiries in his work “Reise nach dem hohen Norden, Frankfurth-a.-Main, 1819.” Furthermore R. Everest, who travelled through Norway to the North Cape in the years, between 1825 and 1830, has collected various notices on the mountain structure of the countries in his work entitled “Journey through Norway.”

When I commenced these notes at the beginning of this year, I expressed a regret that “I cannot include the Aptien and Neocomian species, but the collections at present open to me are too meagre to give anything like a complete account of them.

Greg, and likewise Heddle, found cavities in certain portions of this iron, some of the size of a pea, which are filled with metallic lead; this is the only instance where that element has been met with in a meteorite. Dr. Lawrence Smith has recently examined several specimens cut from the original mass, and is of opinion that the lead is altogether foreign to the iron, being doubtless derived from material with which the block was probably treated by the original discoverers for the purpose of extracting some noble metal from it. The lead, he finds, occurs only in cavities near the surface of the mass, which have channels of more or less size leading to the surface. In pieces of the iron detached from the interior of the block and free from fissures no lead could be discovered.

Mr. R. Mallet’s paper on this subject, of which an abstract appears in the Proceedings of the Royal Society, as read January 21, 1875, lays claim to a certain amount of originality in the views propounded by him, to which, as well as to the correctness of some portion of them, exception must be taken; though it may be that the conciseness of an abstract will to some extent account for what appears imperfect in its reasoning.
