I Quite agree with Mr. Goodchild's statement in the July Number of the Geol. Mag. that the stratigraphy of some of the areas in which the Coniston Limestone Series is developed “presents very considerable difficulties,” so much so that in the areas of Cross Fell and Settle portions of the “country might be described as consisting of a gigantic fault-breccia,” and that it is necessary “to go over a large part of this faulted area again and again” in order to interpret its structure. I do not know whether Mr. Goodchild would class me amongst the “less fortunate” ones who have not been over the ground again and again; possibly I have not devoted the amount of time which he has been able to give to the study of the rocks of the Cross Fell Inlier, but it must be remembered that Prof. Nicholson, with whom I had the pleasure of working at this inlier, has returned to the ground again and again during a long course of years, whilst more recently, he and I have devoted several vacations to its study, and we have carefully compared the beds and their fossils with those of adjoining and more distant areas.
