166 Mr. Farey’s Reply to Mr. Bakewell’s Letter. 
on here to add, that such a familiar and simple illustration 
as this, is so defective, as to be unworthy of the science, 
and of the pages whereim Mr. B. has placed it. “i 
Mr. B. says at p. 123, speaking of Nottingham, that he 
understands me to maintain, that “the sand rock which 
rises from the vale-of the Trent, owes its elevation to this 
fault,” (see also p. 212, of his Geology), whereas no in- 
ference more contrary to all that I have said, could have 
been made :—in Rep. i. 132, I have mentioned Nottingham 
to be seated on Gravel Rock or concreted Gravel (the ** sand 
rock’’of Mr. B.) lieing on the horizontal Red Marl, here but 
little if at all deranged by the fault, as above mentioned herein; 
in Rep. i. 469, I have represented the vale of the Trent to be 
excavated in this Red Marl, and at p. 132, I have spoken 
of the probability, that the parts torn from the southern 
end of the forest mass of Gravel (not by the fault, but by 
the external force which excavated the valley) have been 
scattered up this valley, across Derbyshire, into Stafford- 
shire. 
Is it mot rather extraordinary, under this mistaken im- 
pression hy Mr. B. that Nottingham, at the commencement 
of the Fault, should be the only place which he is able ta 
refer to? (p. 123), as having been explored by him, in 
searclfof a phenomenon, stretching across all Derbyshtre, 
and of which he says, p. 122, that I had traced its course 
with such minuteness, in my Map of Derbyshire! 
Mr. B. has uo right to dictate to ine the number of words 
or of pages, in which I shall reply to Ais attacks on my 
Geological facts and deductions, which notwithstanding 
what he has «aid in p. 123, commenced in &is Leetures at 
Manchester, if not earlier, as appears from the Letter of a 
friend in that Town, now before me, dated November 8, 
1811 (not five months after my first volume appeared) ; and 
from various other quarters in the mean time, have I been 
informed, that, what Mr. B. conceived to be “ faulis ” in 
my work, he held up thus unfairly, in caricature, to the 
censure of incompetent judges, as a great part of his au- 
diences necessarily must be, while a great portion of the 
facts published by me, were detailed by lim, as the results 
purely of his own investigations *. 
That these were the features of Mr. B’s unfair verbal 
* Mr. B’s “ Advertisement” stitehed in your 183d Number, intimates, 
that the facts illustrative of the principles laid down in his “Introduction to 
Geology,” are exclusively “‘ drawn from different parts of England and 
Wales, which the author has examined,” and “the most important observa- 
tions and recent discoveries of eminent Geologists on the Continent !”
