Traces the occurrence of the New Eed Sandstone from Ripon, until 
it gradually thins out to a very thin flaggy atone near Conisborough, 
and at Nottingham dies away altogether. He " has no hesitation in 
affirming that the well-known picturesque ' Plumpton Rocks,' near 
Harrogate, are identical with the Quartz Conglomerates of Germany, 
whether as regards their ingredients, colour, false-bedding, or massive 
stratification." He entirely disagrees with Mr. E. Howse and Mr. 
E. W. Binney.

Describes numerous sections, from Barwick-in-Elmete, East of Leeds, 
northwards, showing, in some cases, the strata underlying the Permian 
Limestone to consist of Shales, and in others of various Grit Rocks, and 
that in every instance they are not deposited conformably to the Lime- 
stone, and concludes, " that along the base of the Magnesian Limestone, 
from Garforth, East of Leeds, to Knaresborough, striking across partly 
Coal-measures and partly Millstone-grit, there is no such thing as 
* Lower Red Sandstone,' or 'Rothliegende,' but that any red or purple 
Shales, Sandstones, or Grit, occurring along this line, are simply Coal- 
measures or Millstone-grit beds, as the case may be, which have been 
coloured through the agency of the overlying Limestone."

Disagrees with the authors in their classification of the New Red 
Sandstone, and says : " When it is seen following the course of the 
Magnesian Limestone, from where the Coal-measures lie comparatively 
flat in North Durham, and passing into Yorkshire with the Magnesian 
Limestone, and there seen with it, resting sometimes on Coal-measures 
(Pontefract, Pebbley Dam, &c.), and sometimes on Millstone Grit 
(Bjiaresborough, Bramham Park, &c.), and in some cases actually passing 
up gradually into the overlying Magnesian Limestone so as to render 
their exact separation impossible (Knaresborough), it is my opinion 
that the physical evidence quite suffices to show that the most appro- 
priate classification for this Sandstone is with the Permian, and not with 
the Carboniferous Rocks."
