tofore expi'essed by one of us on this point ^ and classing these 

 "Tea-green marls" also as Keuper. 



In the smaller pit a few more feet of Lias are shown than in 

 the larger one. Resting on the Rhajtic Shales, of which some 

 16 or 17 feet are here exposed, and sharply defined therefrom, 

 come a few thin bands of alternating fine and coarse-grained flaggy 

 limestones and fissile shales, 1' %" in thickness, containing Am. 

 planorbis, Grypliea arcuata, Ostrea Liassica, Lima gigantea, Pecten sp., 

 Serpula sp., the coarser seams being entirely made up of shell- 

 fragments, joints of Pentacrhms psilonota, and the plates and spines 

 of Cidaris Edwardsii. Above the limestone there are exposed in this 

 pit about 7 feet of thinly-laminated blue shales. 



The dip of the rocks is about 2° in a north-east direction. A small 

 fault with downthrow on the east crosses the larger pit near the 

 foot of the tramway. 



The Boulder-clay rests in a cavity worn out of the Lower Lias 

 and Upper Eha3tic shales. It consists mainly of recomposed Keuper 

 Marl and contains boulders of quartzite slate and granite, Keuper 

 sandstone, Eh^etic and Lias limestone — beautifully smoothed and 

 striated — also ironstone nodules, and an occasional chalk flint. As 

 is usual in this district, the Boulder-clay contains pockets of 

 ferruginous pebbly sand. 



At the brick-yard the whole of the different clays are worked up 

 together, viz. Boulder-clay, Upper and Lower Eha^tic Shales and 

 Keuper Tea-green and Eed Marls, the coarser fragments of the 

 Boulder-clay, and the Eheetic and Lias limestone having been 

 previously picked out. This combination -clay is manufactured into 

 bricks, drain-pipes, tiles and ornamental pottery. 



Mr. Healey, to whom we are indebted for every facility for 

 examining the above sections, informs us that it is probable that 

 before very long the smaller pit will be deepened. If so, they will 

 strike into the Paper Shales, and give geologists another fine section 

 of these interesting: rocks.

 rjlHE announcement in 1862^ of the discovery of a nearly entire 

 _L skeleton of a most remarkable long-tailed Bird, clothed with 

 feathers, in the Lithographic Stone of Pappenheim in Bavaria, named 

 by Prof. Owen Archceopteryx macrura, produced a most profound 

 sensation amongst biologists generally. A single feather had, it is 

 true, been already discovered in this formation in 1860, and named by
