Mr. Farey’s Notes on Mr. Bakewell’s Geology. 125 
[P.200] vast beds of Till, S of the Ochills (WernerianTrans. i, 48 1) 
appear also, other instances to show, that the skirts of 
Mountains and mountainous countries, are less commonly, 
strewed with the worn fragments of their own Rocks, than 
seems here by Mr. B. and is very generally, assumed, by 
Geological writers. 
201, 1. 18, by other processes *.—* Why may not there be 
vast regular strata of Sand? 1 have met with nothing to 
contradict such a conclusion ; but much to confirm it, see 
my Note on p. 60. 
202, 1. 10, classed with alluvial products*.—~ * Very. few 
Breccias or Conglomerates, will perhaps, come ‘into this 
Class, see my Notes on pages 44 and 50. In Anglesea, I 
haye lately had the opportunity, rather unexpectedly, of 
seeing a conglomerate Mass or Rock, such as I had not 
previously noticed, in examining, what I conceive to be the 
same series of Strata, in the Great Forest of Brecon, and 
other parts of the edges of the great Seuth-Wales Coal-basin 
or Trough, and of those of the Forest of Dean and of the 
Clee- Hills. 
This Anglesea conglomerate I first observed, at the SW 
corner of a very poor common, called Rhos-mirch, 3m. 
NE of Llangefni Town, from which a new Road is about 
to be made, under Mr. Maughan, the Commissioner for the 
Inclosure, across this common, There is a quarry open in 
this Rock, from whence a Cottage has lately been bvilt, just 
by it, and this stone is used also in several other Buildings

stratum, wuderlicing the red mottled Clay, as is stated, at the top of page 
396. 
In p. 482, the description is given, of a patch of alluvial chalky clay, 
resting on a detached hummock of hard Chalk and green Sand, in the 
Chalk-marl district, near Foxton, in Cambridgeshire, “ situated do the west 
of the great range of Chalk ;” and yet the writer would persuade us, that 
the numerous pieces of worn Chalk and Flints in this Clay patch were 
Jodged there, by “ an ancient current, the course of which was from West 
to East !.” : 
It may perhaps be doubted, whether this Gentleman is possessed of the 
means of knowing certainly, the organic remains older than the Chalk, from 
other reliquia? or, that he can show, that no such: shelly Limestone Strata, 
and Rocks of Greenstone, ashe alludes to, occur in Europe, ¢o the South-east 
of Cambridgeshire?—~on failing in which showings, Mr. Smith’s and my 
multiplied observations, as to the removal of known alluvia from SE to NW, 
will stand unaffected, by this pretended case to the contrary. This is a 
subject, which I believe Mr, Bakewell has overlooked, see my Note on 
page 52,
