Farey’s Notes on Mr. Bakewell’s Geology. 361 
to me, to approach very nearly to the nature of 
statuary Marble. If 1 misiake not, allthe masses 
of white granular Marble, or of Breccia Marble, 
which i have yet had the opportunity of examin- 
ing, in situ, belonged to Dykes or Veins, and did 
not form strata, see Rep. i. 413 and 414, and my 
Note on p, 73. 
4, neyer visited *,—* Has Mr. B. examined any 
active volcano?, before he ventured to describe 
England as a volcanic Country, p. 306, 307, &c. 
and to affright our ancient Ladies, with the im- 
pending fate of the Matrons of Pompeii and Her- 
culaneum, by the sudden activity of the dormant 
Volcanos, which occasion (he says) the hot waters 
of Bath, Bristol, Matiock, Buxton, &c.!! 
20, basaltic rocks *.—* If such Rocks differ in no 
essential particulars from other regular strata, as 
Mr. Williams, a practical Collier in the very vici- 
nity of Edinburgh concluded, Min. King. 2d Edit, 
i. 66 and 123, &c., and as I maintain, aiter a 
more extended examination; the second inunda- 
tion of the Wernerian theory, here alluded to, ap- 
pears equally unnecessary and ‘‘ imaginary,” with 
the subterraneous Volcanos of Mr, Whitehurst, or 
the submarine ones of Mr. Bakewell, P. M. xl. 
p- 47, and Geology, p. 93 and 122. 
18, partial formations *.—* See my’ Notes on 
p- 116, p. 98, &c. 
8, interior parts are columnar*.—* The reverse 
of this is generally, if not universally true, and 
the owisides of Basaltic hills are often locally co- 
Jumnar, where their interior has been proved to be 
homogeneous and solid, as Mr, Williams has truly 
stated Min. Kin. 2d Edit. i. 67, 68,&c.and M. De 
Luc’s Geo. Trav. in France, it. 240: When I 
viewed the curious horjzontal Basaltic columns 
in Powk-hill, in 1808, and the compact basaltic 
stratum (or ‘ Greenstone’) in Birchhill Colliery, 
near and ‘‘in the deep of it,” NW of Walsall, 
Staff. I concluded them to be parts of the same 
regular stratum, and with the lamellar and de- 
composing Basalt also, in Daisey-hill, near to the 
Colliery, and the perusal of page 392 in your 
xlth vol. has not in the least altered this opinion, 
sce my Note on p. 315. I have been told, that 
regular Basaltic strata occur also in the Bedworth 
Coul-
