116 Slate, &c. in Charnwood Forest is not stratified. 
(on a subject that I had not introduced), and in different 
parts of the Geology, had given me reason to hope, that T 
should, from a perusal of the whole, add greatly to my stock 
of knowledge, of the interesting district called Charnwood 
Forest: the first tract which I examined in my Survey, 
containing substances which I had not any where previously” 
seen ‘in situ,” and yet hurried greatly, compared with 
any parts of Derbyshire; my expectations have however’ 
been much disappointed. 
Respecting the stratification of the slate, 1 had thought: 
that it might have been easy for Mr. B. to have added in 
this postscript, the range and dip, (as to direction at least) 
af Rocks ‘* most distinctly stratified ;” but at page 288, of 
the Geology, the contrary of this appears, after an awkward 
sort of introduction, in the following words: ‘* but I am 
persuaded that what resembles stratification 1s the result of 
crystallization on the mountain mass, by whieh it has se- 
parated into thick tables or plates, that are of limited ex- 
tent, or wedge-shaped*.”” Which nowise differs in mean- 
ing, from what I had originally stated, Report 1. 155; and 
common candour might have dictated an additional remark 
from Mr. B. or a note, stating, that the cbservations of a 
previous writer had been too hastily objected to on this 
head. 
As further proofs of Mr. B’s confusion on this same 
subject, it may be proper to notice, that in his postscript he 
says, the stratification of the slate is ** in an opposite al- 
rection to. the slaty cleavage ;’’ at page 87 of Geology he 
says: the slaty laming make an angle of sixty degr ees with 
the principal seam by which the rock is divided ;” and yet, at 
p- 288, we read, ¢* the slaty cleavage of the stone is nearly 
at right angles with the direction of the beds.” Such are 
the eonsequences, of precipitancy, and the want of a little 
straight-forward candour and liberality, towards others en- 
gaged i in the same pursuit. 
Notwithstanding all that «*T have been compelled ” 
say in this and my Ist Letter, in condemnation of parti 
cular parts of Mr. Bakewell’s ‘* Introduction to Geology,” 
it nevertheless contains much that I wish greatly to recom- 
mend to the notice of Geological Students, and on that 
account I shall in future Letters send you, a series of Notes, 
remarks, and references in the order of its pages, and am, 
Sir, your obedient servant, 
Upper Crown-street, Westminster, Joun FAreEy Sen, 
2\st July, 1813.
