Being unable to proceed further with this work, I venture to put forward the results of my observations, in the hope that they may be of use to those who continue the study of these rocks. I should like, at the outset, to say how greatly indebted I am to Mr. Marr for all the help that he has given me; he has not only placed at my disposal his own maps of the area and the details of his own observations, but has always been ready with encouragement and advice.

The Volcanic Series runs in a broad belt, 12 or 13 miles wide, across Cumberland and Westmorland. In order to become acquainted with the various features of the garnetiferous rocks, I have attempted to cover some 130 square miles of ground ; and as the greater part of this area has only been visited once, I feel some diffidence in drawing any conclusions from so hurried a survey. Perhaps the most interesting of these garnet-bearing rocks are those which occur as dykes and sills intrusive in the Volcanic Series. They are chiefly to be found in the central part of
