8. Thin band of highly fetid, finely laminated, whitish grey 



marlstone. This bed contained the fossil fox. The fissile 

 nature of this stone has occasioned it to split into two slabs 

 with such uneven surfaces, that characteristic portions of 

 the bones or impressions of them are seen in each. The 

 slab containing the more perfect portion of the animal has 

 been selected by Mr. Mantell for his operations of clearing 

 away the surrounding rock. It is worthy of remark, that 

 the fox and the great tortoise present themselves in their 

 fossil state in such an undisturbed position, that we may 

 suppose them to have scarcely moved after they sunk down 

 amidst the fine silt and mud of the ancient lake, with which 

 their bones have since become partially mineralized. In 

 this layer also occur other organic remains, among which 

 are fishes of great size, one of which in a very perfect state 

 had just been found previous to my first visit, and resembled 

 a large pike 5 



9. Two or three fine layers of marlstone, differing very little from Nos. 7. and 8. 



and containing leaves , 10 



10. Great building stone of granular texture; it resembles somewhat No. 4. but is 



harder, and is considered the best building stone of the quarry. In its less 

 adherent parts shells of Anodoiita Ijuvateri are disseminated, with their 

 "nacre" well preserved; and fishes are also found between the lamiuce of 

 division 4 g 



1 1 . Finely laminated, white, slaty marlstones, resembling Nos. 7. 8. and 9. in slabs 



of three to six inches each, and containing fishes, plants, Anodonta, &c., 2

Here the work was stopped by water, in the autumns of 1828 and 1829, 

 owing to the wetness of those seasons ; but in dry weather several inferior, 

 slaty layers are to be seen, and beneath them the micaceous sandstone or 

 molasse. 



The adjoining quarry, which is to the north-west of the preceding, consists 

 of beds of rather a more arenaceous texture, and of a darker colour than those 

 just described. These beds contain plants and fishes, and a great number of 

 Anodonta Lavatcri, but none of the insects which characterize the more 

 finely laminated layers of the middle and lower beds. 



All the strata are nearly horizontal, having only a very slight inclination of 

 two or three degrees to the south ; and hence it may be inferred, that the
