1853.] BELL BORING AT KOTAH, DECCAN, 351 



Around the edge the blocks of nummulitic hmestone (or conglomerate 

 of pebbles of such rock) were hardly disjointed from the nearly level 

 surface-stratum. Higher up the blocks became more dislocated and 

 discoloured as by fire ; a little higher they were more or less fused, 

 and at the top of the heaps had often the appearance of vitrified slag. 



The water of the warm springs in the Sehwan Hills has generally 

 a trace of sulphate of lime ; sometimes, indeed, is highly impregnated 

 with it. 



Some months ago I forwarded through the Bombay Secretariate 

 a box of specimens of the sulphurous earth found in some localities 

 near Kurachee. It is not, I expect, pure enough to ])e worked 

 economically.

7. Further Account of the Boring at Kotah, Deccan ; a7icl a 

 notice of an IcHTHYOLiTEy?'om that place. By Dr. T. L. Bell,

[Communicated by Col. Sykes, F.R.S., F.G.S.] 

 [Abstract.] 

 In the August number of the Quarterly Journal of the Society for 

 1852 (vol. viii. p. 230) is an account of the boring lately made at 

 Kotah *, in the Deccan, in the search for coal ; and at page 2/2 of 

 the seventh volume of the Journal is an account of the fossil fish 

 {Lepidotus Beccanensis) from the bituminous shale met with in the 

 boring. In the present communication Dr. Bell states that, on ac- 

 count of the washing in of the soil, it was found necessary to make 

 a new bore. After taking precautionary measures, by constructing 

 a wooden shaft through the alluvium, the boring was carried through 

 the 27 feet of limestones, shales, &c. that were penetrated the pre- 

 vious year (1851), and a further depth of 64 feet 1 1 inches attained. 

 This consisted of 



ft. in. 



Limestone 23 



Blue clay 7 6

Shale and clay 1 9 



Limestone (more compact and crystalline) 1 8 



Blue clay and shale 12

* The position of Kotah is indicated at p. 272, vol. vii., but the following note 

 gives it with greater definiteness : — Kotah is situated close to the confluence of 

 the Godavery and what Arrowsmith, in the edition of his map in 1840, terms 

 the Wandah, but which in this part of its course, — that is, just before its junction 

 with the Godavery, — should properly be called the Pranheeta. Kotah is on the 

 left bank of the river, and nearly in the same latitude with Chinnoor. [General 

 Fraser, in Letter to Col. Sykes, F.G.S.] A Map of this district will be found in 

 the Transact. Geol. Soc. 2nd ser. vol. v. part 3. pi. 46; and remarks on the lime- 

 stone of the vicinity, ibid. p. 568.
