Mr. Farey’s Notes on Mr. Bakewell’s Geology. 255 
[P.259] might have introduced his name, as hinted in my|stLetter, 
vol, xlii. p. 58, as well as noticed the laudable endeavours 
towards ascertaining the order und thicknesses of the strata, 
by your able correspondent Mr. Dayid Mushet, P. M. vol. 
xl. p. 50, and even by the Rev. Mr. Mitchell, Rep. i. 
109 N. and P. M. xxxvii. p. 175 N, and xxxix. p. 94 N. 
In one point of view, we have all reason to be thankful to 
Mr. B, that our Names have not been coupled with such 
very erroneous statements, as are made in the following 
pages, and at p. 283, by Mr. B, as to the ‘¢ strata containing 
Coal” (beneath the Lias and upper Red Mar!) being only 700 
yards beneath London !, and not deeper at Woburn, than 
some of the Newcastle Coal-pits!!. See the article Coat 
in Dr. Rees’s Cyclopedia, written in 1805, where this sub- 
ject has been considered. 
262, 1. 9, their known limits *.—* Here, and at page 284, is 
as bold an attempt to set up wild theory against just in- 
ferences, from undeniable and unvarying facts, respecting 
England at least, as ever was made :—all experienced Coal- 
miners know, that seams of Coal, or other strata, ‘* never 
go out to the deep,”’ or never terminate in the direction of 
their dip ; except sometimes suddenly against a fault, and 
are then only thrown up or down, and are not “ cut off,” 
incomprehensibly, see a note on this subject in my 2d Let- 
ter, vol. xlii. p. 105. In one page we are recommended 
to expend the national Treasures, in search of objects, which 
in the next we are told do not exist,—perhaps a sly hit was 
here intended, at several wise ministerial expenditures, 
within the last 20 years. 
263, 1.8, strata under chalk *.—* In one sense, this is un- 
doubtedly true, of English Fullers’ Earth, owing to the 
Chalk being almost at the top of cur Series, but not in that 
here intended, in alluding to the Surry and Bedfordshire 
Fullers’ Earth, because Red Marl produces a sort of this 
Earth, in different places, as at Brathwell, Rep. i. 465, and 
P.M. xxxix. p. 105, near Nottingham, &c. The neighbour- 
hood of Bath also produces this Earth, if I mistake not, &c. 
1. 24, with fossil wood+.—t+ The wood and animal re- 
mains here alluded to, I think, are found in the stratified 
blue Clay of Highgate, Hyde-Park, Brentford, &c.; but 
the large animal Bones were in the alluvium upon this clay, 
see my Notes on pages 16, 181, 258, &e. 
264, 1. 19, found east of it*.—* Query, see my Ist Letter, 
xlii. 57. 
265, 1. 22, expansion of the Basalt*.—* Except the large 
Whin-dyke across a very high part of these Moors, where
