Inworking for the first of our papers—as willbe seen from the remarks and quotationsin the final one *—we fear that we ratherslurred over this locality, as it had already received so much result is a useful warning to geologists not to neglect evena locus classicus when new methods of investigation have beendevised, or the point of view has been materially altered.

NORTH-WEST REGION OF CHARNWOOD FOREST. 93 however, plead in excuse that some of the most important evidencewas disclosed by quarrying subsequent to our visits, and that it isonly during the winter and early spring that the hill itself can bereadily examined, as it is so much overgrown during the rest ofthe year by brushwood and coarse herbage. On the last occasion a dyke of granite, some 4 feet wide, was ex-posed, running from the top almost to the bottom of the north-western wall of the pit, where it was still concealed by the micaceousrock. There was also another mass, not so well exposed, in wall, and the end of a vein just showed itself in the wallbetween these. We are certain that these junctions were concealedat our visits prior to 1877, and the great dyke was not visible evena year or two later than that date. We were able to examinecarefully the knoll at the back of the pit, and found several smalllow^ outcrop
