tracts, which is inferred to have been deposited at the close of the 

 glacial period. The origin of this bed and of the clay-with-flints is 

 treated of, W. W.

 around Bristol, and describes the eruptive rocks of the Tortworth

 The tract described is the central part of the Yale of York. The 

 general dip is N.E. ; but the Palaeozoic rocks in the west are thrown 

 into folds striking N.E. and S.W. The formations described are : — Yore- 

 dale Bocks (shales with limestone and sandstone) ; Millstone Grit (stone 

 and shale), in which coal has been worked ; Permian, in four some- 

 what unconformable divisions — the Lower Marl (marly sandstone), 

 Quick Sand, Lower Limestone, about 175 feet thick, and the Upper 

 Limestone ; Trias (Bunter Sandstone and Keuper Sandstone and Marl) ; 

 Lias. The Post-Pliocene deposits, which "have more influenced the 

 physical structure of the country and the nature of its soil than the 

 rock formations previously described," are then noticed under the fol- 

 lowing heads : — Glacial (Local Drift, Erratic Drift, Middle Sands and 

 Gravel, Moraines, Esker Drift) ; Post- Glacial (Estuarine beds, Warp 

 Clay, Lacustrine Deposits, AUuvium and Eiver Terraces). In conclu- 

 sion the "■ Physical Structure " is described at some length. There 

 are short lists of Eossils from the Millstone Grit, from the Magnesian 

 Limestone, and from the Estuarine beds, and details of a bore-hole at 

 Bog Lane, Harrogate. W. W.

An account of the literature of the subject is first given ; and then 

 the geological formations are described, in ascending order, beginning 

 with the Chalk, the places where it crops out being noticed, and also 

 the various depths at which it has been found in wells. The Reading 

 Beds and London Clay follow next, and many sections are named. The 

 *' Box Stone Deposit " is then described : it underlies the Crag, and is 

 characterized by containing many large flints, foreign boulders, and
