V.—Geology of the Channel Islands

Extract

In the most extended view, the Channel Islands may be regarded as fragments and relics of the Eastern or European coast of the Atlantic, reckoning from the North Cape to Cape St. Vincent, and including the Western shores of Scotland and Ireland, and the promontories of Pembrokeshire and Cornwall. They are excellent illustrations, says Professor Ansted, “of those spurs and tongues of porphyritic rock, of which almost all the promontories of the Atlantic coast of Europe consist.” Very small and insignificant specks indeed they seem in such a length of coast, stretching from lat. 37° to 72°, or upwards of 2000 miles; but there is a charm in such wide horizons, and it is a very allowable indulgence so to connect the little with the great, and to consider the position of such little specks in relation to the geography of Europe; one might almost as well say, of the world at large.
