Coprolites from the Gault at Folkstone.

There was, I believe, only one coinage of farthings in the last 

 reign, namely, that of 1822, and supposing that the full term 

 of 13 years had been occupied in forming the mass, it is a 

 curious fact; but I conceive half that time would be as much 

 as we could fairly allow. Might not indestructible garden 

 walks be formed by mixing small fragments of iron and com- 

 mon salt with the gravel? — S. Woodward. Norwich, Nov.

Art. XVII. Queries and Answers. 



What are those Bodies, some circular, some oval {fig. 13.), 



which are to be found in 

 the Gault at Folkstone ? — 

 They are not unlike 

 the coprolites figured in 

 the Geological Society's 

 Transactions, discovered 

 by Dr. Buckland in the 

 oolitic group, and some 

 of them have the appear- 

 ance of containing undi- 

 gested remains, which is the case with those of Dr. Buckland's 

 communication ; of this sort is b, of which I have sent a 

 sketch above, the prominence marked (a) resembling part of 

 a limb of a crustaceous animal. They are covered with 

 furrows and small punctures, and are of a light-yellowish clay 

 colour, internally black, very heavy, and difficult to break. 

 They are in great numbers, and of all sizes. The four 

 sketched above seem to me characteristic of all the speci- 

 mens I observed. Query : Have coprolites been yet men- 

 tioned as found in the gault ? and, if they be coprolites, to 

 what animals can they have belonged ? to fish ? or to the 

 few Reptilia yet discovered in the cetaceous group ? — H. 

 Hastings, 1834. 



[The reply to enquiry made subsequently to the receipt of 

 this communication is, that the bodies have been long 

 known; and that Dr. Fitton will allude to them in his forth- 

 coming memoir on the greensand.]
