Mr. Webster on the Strata of Hastings, in Sussex. 35 



casts of a small bivalve, which occur rather abundantly, but which are gene- 

 rally in too imperfect a state to enable the naturalist to decide to what species 

 they belong" ; together with a few casts of an univalve resembling those found 

 in the Petworth and Purbeck marbles, and which have usually been consi- 

 dered as fresh- water shells, perhaps Paludinae. These fossils are sometimes 

 also found in the sandstone not calciferous. 



Besides the vegetable remains which I have already mentioned as so plen- 

 tiful in the lower beds of sandstone and shaly clay, portions of the silicified 

 stems of monocotyledonous plants are frequently found in these cliffs, of a cha- 

 racter that deserves well the attention of the botanist. All the pieces I have 

 seen (and they are often found on the beach) are somewhat flattened, and 

 have longitudinal cavities of two kinds, which evidently belong to the structure 

 of the plant : the first small, sinuous, and communicating with each other ; the 

 second much larger, but frequently compressed. Both are lined with beauti- 

 ful minute and transparent crystals of pyramidal quartz, the colour of the whole 

 being blackish brown. 



In masses of the rock that have fallen from the East Cliff, I found, in 1812, 

 numerous fragments of the ribs of large Saurian animals, one of which I placed 

 in the collection of the Geological Society: but I am indebted to the liberality 

 of George Cumberland, Esq., for the use of the following drawings of organic 

 remains found by him in these cliffs. 



Fig. 5. Plate VI. represents several teeth in a portion of a jaw. They are 

 conical and polished. I have not been able to ascertain to what animal they 

 belong, but they have considerable analogy to those of the Lizard tribe. 



Fig. 6. represents the same teeth magnified. The upper part (seen again at 

 fig. 7.), may be easily detached, and seems like a capping of a transparent sub- 

 stance. It is proper to add that I found the same kind of teeth in the Pur- 

 beck beds at Swanwich.

Fig. 9. Plate VI. The dorsal fin of a fish. 



Fig. 10. Plate VI. Bone of a bird. 



Fig. 11. Plate VI. Scales offish : — these are highly polished. 



I may mention here (although it is evidently postdiluvian) the remains of 

 what is usually called a submarine forest, which is to be seen at low water be- 

 tween White Rock and the West Cliff. Numerous trunks of trees lie flat, 

 the wood partly black and partly of the natural colour : they are accompanied 

 by great quantities of hazel-nuts. 



From the character of the calciferous mammillary rock above described, and 

 its organic remains, connected with the geography of the country, I have no
