32. Mr. Farey’s Notes on Mr. Bakewell’s Geology. 
[P.172] ofaconcentric or nodular formation, and contradict 
the supposition, of their being rounded masses of flint, 
chert, or any other stone: a small shell, proves the 
nucleus of one of the Nodules: in great numbers, 
the figures or stripes, curved, fortification-shaped, &c. 
are very beautiful, and the colours quite equal to most 
of those which are washed out of the alluvial red Clay 
on the shore near Whitby in York NR. and are col- 
lected from the beach with such avidity, by the Cu- 
rious, many of whom are not aware, that they might 
find such at their own doors, near London. Mr. 
Sowerby’s collection has long been rich, I believe, in 
these smal] nodular masses, of the London Clay strata.

Gypsum, containing Bones, which | have seen, corre-

being earthy and slightly granular; intermediary in 
structure between Chalk and soft Oalite Limestone.

Clay, on the Marle or Gypsum and not i the Red 
Marle, here or elsewhere, see Rep. i. 136 and 149,

ter, p. 105. 
176, 1.3, The Geological situation *.—* On first reading 
the paragraph which thus commences, and Mr. B’s 
Note thereon, below, I could not help thinking, that 
he was attempting a hoax, on the *‘ well educated geo- 
gnosts,”’ and I was unwilling to suppose, that he was 
himself serious, in adding to the extreme confusion on 
this head, with which he charges *¢ the disciples of 
Werner” in his note on page 174; the point is how- 
ever of too much importance, as to the real succession 
of the strata in England, to be thus dismissed, and I 
will quote Mr. B’s passage, with such references or ex- 
planations in [ ] as appear to me necessary, viz. 
«¢ The Geological situation of the Derbyshire gyp- 
sum may be represented, as situated in the upper se- 
condary strata, separated [below] from the mountain 
lime (i. e. fransition L. p. 92, 93, Map p. 255 &c.], by 
intervening coal districts on one side, aud [above]
