Vol. 51.] CRUSH-CONGLOMERATES OF THE ISLE OF MAN. 599 Mr. E. T. Newton thought that there was some doubt as to theso-called trilobite being really organic. Mr. Marr observed that though somewhat similar results ofdifferential movement had been previously described, the greatinterest of this case described by the Author was the extensiveoccurrence of thick masses of a rock simulating a sedimentary con-glomerate over wide areas. He believed that many similar rockshad been mistaken for true sedimentary conglomerates in otherareas. He noted the discovery by Mr. Harker and himself of rockshaving some resemblance to those described by Mr. Lamplugh,amongst the Ordovician rocks of Lakeland. The resemblance, how-ever, was only a general one. Mr. Watts, in reply to Dr. Hicks, pointed out that the two chiefreasons for bringing forward this paper were : (1) that the con-glomerate occurred over a wide area, and
