in our last Number, &'c. viz. on the great Derbyshire 
Fault.— Mr, B’s Lectures.—Staze-coach Geology.—The 
great Southern Denudation.—Limestone resting on Slate. 
—The great Limestone Fault, &c. 
To Mr. Tilloch. 
Six,—Herewrre I have sent the third * of six letters 
addressed to you, containing my reply to Mr. Bakewell, 
and Nofes on his Geology, which were written in July last, 
according to their dates, but which Letters I shall continue 
sending sing!y,.as your work proceeds, in order that I may. 
interline on their opposite blank pages, such further re+ ‘ 
ferences or remarks as may from time to time occur to mes 
Mr. Bakewell’s second letter, inserted at page 121, 
seems to call for several remarks, which had better be made 
here, than by the interlineations above alluded to. 
The conclusion of my first Letter (p. 59) sufficiently in- 
dicated, that a full answer to Mr. B. on the great Derbyshire 
Fault and other points at issue, was in train, to have 
spared him the trouble of a repetition of his Queries so 
vauritingly addressed to me in your work. On the prin- 
cipal subject of which queries, I had certainly no need of 
twelve months (p. 122) to answer Mr. B., by saying, in 
four words, Read the Derly. Report, as I might have done, 
because there, very clear answers to his queries were already 
printed, see p. 106 herein. 
Those who have examined my Map, Plate I. in your 
xxxixth vol. or my Report, vol. i. must be fully aware, 
that I have spoken of three great faults, by the names of 
the ‘ Derbyshire,’ the «* Limestone, ”’ and the “ Zigzag ”’ 
Faults; yet Mr. B. so often speaks of them in the singular 
(p. 193, J]. 22 and 23, &c.) and confounds his objections to 
them together, that all the attention which I had been able 
to bestow on his letter and book, was not sufficient to 
guard me from errors, in p. 103, lines !7 and 25, in men- 
tioning éwo faults instead of three, and in page 112, in, 
saying, that ore of them, ‘‘ the great Limestone fault,” had 
escaped Mr. B’s open attack ; because I now discover, that 
he alluded to this Fault in vol. x], near the bottom of p. 45, 
(although not before named), and near the bottom of p. 124 
herein. 
'* Want of room obliges me to defer till next number the Letter referred 
to by Mr. Farey, commencing the series of Notes on Mr. Bakewell’s Geo- 
logy.—A. T. sey ;
