#69 Mr. Farey’s Notes on Mr. Bakewell’s Geology.

than to suppose, with the Huttonians, that the 
Granite has been * forced through the more su- 
perficial covering of the Globe ;” when after all, 
the Granite may perhaps be comparatively an incon- 
siderable nodule or crystallized mass (Rep.1. 153)» 
in a Stratum, of far greater magnitude and ex- 
tent, see my Note on page 43. 
67, 1, 10, over coal *,—* What reasons, except his new 
«¢ Anglo-German” theory of formations, has Mr. 
B. adduced, to show, that the Coal-measures of 
the Ashby-de-la-Zouch Coal-field do not pass 
under his ‘ primary” (or ‘* Transition”) tract 
ealled Charnwood Forest? see my note on page 
285.—At page 286 Mr. B. admits. that the Red 
Mar! (under his new denomination of Sazdstone), 
occupies a space, in horizontal strata between the 
Coal-measures and the coarse Slate, and says, the 
Sandstone is evidently of ‘ posterior formation to 
the coal strata,””) or in plain English I should say, 
lies upon them ; but which Mr. B. was not likely, 
to say, wishing for another purpose, to represent 
this same Red Marl (or Sand-stone) as identical 
with IstGrit and Limestone Shale (or Sandstone), 
and underlying all the great Derbyshire and York \ 
shire Coal Series, see my 2d Letter (p. 103). 
The coals rising up where they terminate 
against the horizontal Marl, as Mr. B. men- 
tions, is consistent with the Fault which I 
have represented in my Map Rep. i. p. 97 and 
mentioned p. 174: and though Mr. B. may have 
attempted to invalidate this Fault, in another part 
of its course, at page 267, by saying, “on the 
south-west they (the Coal-measures) are covered 
by a thick bed of coarse breccia and gravel, which 
separates them from the coal-fields at Polesworth 
and Bedworth inWarwickshire ;” his statement is 
clearly unfounded ; for between these two Coale 
fields, several miles wide of as perfect Red Marl 
occurs, in horizontal strata (with occasional grit- 
stone beds in them), as in any part of England, 
as my Map shows, Rep. i. 97, instead of Breccia 
and Gravel!. I have shown and mentioned a 
small tract of Gravel Rock ? in Over Seal (Rep. i. 
142), which Mr. B. may perhaps have seen, and 
thus been induced to make this general and very 
unfounded assertion,
