During the past year I had the pleasure of spending some weeks on the north coast of Cornwall, south of the Camel, examining the rocks exposed in the cliffs and on the foreshores of the various coves, some of which I had not previously visited. A part of my notes were communicated to the Annual Meeting of the Royal Geological Society of Cornwall last November, and with the permission of the Society I propose to reproduce these and additional observations obtained since, with the view more particularly of calling attention to some of the fossils which, though fragmentary, appear to me to yield not unimportant evidence on the stratigraphical horizon of the rocks along certain parts of the coast.
