of the Chalk-marl over an extensive tract of country, ly mere at- 

 tention to its Fossils," but for reasons best known to himself, Mr. 

 G. omits here, the reference, to the work to whicli he alhides, in 

 making this important assertion. After reading through all Dr. 

 Lister's Papers in the Phil. Trans., without discovering any such 

 thing, I was induced to look into his Work entitled " Historiae 

 Animaliuni Angliae," wherein, at p. 228, at the endof the descrip- 

 tion of the small Belemnite, engraven in his 32d title or figure, are 

 these words, viz. " Locus'. Huiic lapidem plurimis in locis apud 

 DOS quam copiosissime inveni: at perpetuo in terra, rubra ferrea, 

 sive ea mollior gleba, sive saxea sit. In all the Cliff's, as you 

 ascend the Yorkshire and Lincolnshire Wooldes for above 100 

 7niles in compas : as at Spiton, Lawnsborough, Castour,Tedford, 

 Calkwell :" which doubtless is the passage, to which Mr. G. al- 

 ludes, and the first part of which, a learned naturalist of my ac- 

 quaintance*, renders thus, viz. " This stone is found very abun- 

 dantly in many places amongst us, in a red ferruginous Earth, 

 either in softer or in more stony masses. In all the CHffs," &c. as 

 above. 



On which, I beg to ask Mr. Greenough, how he can make out, 

 that the red ferruginous Earth, here alluded to by Dr. Lister, at 

 Specton Cliff, Londsborough, Caistor, Cawkwell, and Tetford (as 

 the places are now called), is the iv/iifish, or hlueish or greenish- 

 gray "Chalk-Marl "f, rather than the " Brick-earth ?" or mica- 

 ceous blue Marl (exposed and oxidated) p. 13, of Smith's "Strata 

 Identified," wherein such small Belemnites, are found, and de- 

 scribed. And next, I will take the liberty of saying, that Dr. Lis- 

 ter does not appear to me, either to have accomplished, or to have 

 had in view, the tracing or following of any particular Stratum, 

 by means of these small Belemnites, by reason that he never men- 

 tions the same, or speaks of its relation to the Chalk Strata near 

 adjacent and above it in the Series ; but intended merely to ex- 

 plain more particularly, by the mention of Cliffs at the edge of 

 the Wold Mills, the situations in which he had found these Be- 

 lemnites. It is however, a singular circumstance, that this pas- 

 sage, and this only, should be given in English, in Dr. Lister's Latin 



• At my request, the same kind friend, looked carefully througli all this 

 work of Dr. Lister's, in order to inform me, whether theie are any other 

 passajres therein, favourable in any way to the assertions Mr. Greenoufrh has 

 made, regardin;^ Dr. Lister's knowledge and use of Fossil Shells, in traciriff or 

 Jollowinii Strata, by their means ? : and liis answer is, " It does not appear 

 that Dr. Lister, eillier traced the Strata by the Shells, or tlie Shells by the 

 Strata ; it also appears, that he often confounded several Species under one 

 Title."

 pears to have dropped, and included thij Stratum in the " Cirecn Sand," of 

 his Map and I'u))lieations.
