In the middle of the extensive plain which is bounded by the slopes of Bovey, are the potteries of Mr. Divett, for which fuel was formerly supplied by the lignite excavated there. In order to obtain this lignite a deep cutting has been made, and a sort of small ravine formed, on the sides of which the stratification is exposed. The surface-covering consists of a light-coloured quartzose sand, which contains here and there considerable beds of white clay. By the plants contained in it this formation is assigned to the Diluvium. Immediately under it come the beds of clay and lignite described by Mr. Pengelly in the foregoing paper, which are all referable to one formation, as several kinds of plants are common to the different beds. The Sequoia Couttsiœ and Pecopteris lignitum occur in the 7th, 17th, 26th, 40th, and 63rd beds. Carpolithes Websteri is certainly found in the greatest abundance in the 54th bed, yet occurs also, though very rarely, in the 25th bed; Cinnamomum Scheuchz and C. lanceolatum in the 17th and 26th. The formation to which these strata belong is far older than that of the overlying white clay; the plants found in the former prove them to belong unquestionably to the Miocene period, and accordingly we must treat of them separately.
