those of the ox and sheep, or, at any rate, to have been subjected to 

 different conditions as regards exposure &c. 



4. Incerta. — The other remains from this level are eighteen or 

 twenty broken and rolled fragments of long and flat bones of some 

 large animal or animals, not improbably Elephant, Ehinoceros, or 

 Hippopotamus. Most of them are too imperfect to allow of correct 

 determination ; and allare extremely friable, loaded with manganous 

 oxide, and apparently retain very little animal matter, since they 

 neither blacken nor smell when burnt. As they are, as above said, 

 much rolled, it may be presumed that they may have formed part 

 of a previous deposit. But amongst these remains is a large portion 

 of an elephant's molar, which will be referred to subsequently. 



II. MiD-TEEEACE GkAVEL. 



The remains from the Mid-terrace Gravel, with one or two excep- 

 tions, all present characters of great antiquity. They are all highly 

 dendritic, and adhere strongly to the tongue. They vary, however, 

 a good deal in colour, many being white and chalky, except where 

 stained with manganous oxide, whilst others are highly ferruginous. 

 They present no evidence of their having been water-worn or rolled ; 

 and from the circumstance that several portions of the same skeleton 

 have occurred at no great distance apart, it would seem probable 

 that the carcasses of the animals had been deposited more or less 

 entire not very far from the locality in which the bones were found, 

 viz. a bight of the ancient river. 



The bones of decidedly recent origin (five or six in number) belong 

 to the Horse (of which a nearly entire skeleton was found in one 

 of the pits) and Ox, the latter species being represented by the 

 proximal end of a liumeriis, whose shaft has been chopped across ; 

 most probably an old marrow-bone. 



The really fossil bones belong to the following species : — 



I. Peeissodacttla. 



1. Rhinoceros hemitoechus. 



2. Equus cahallus. 



II. Aetiodacxyla. 



3. Hippopotamus major. 



4. Bos taurus {primigenius^. 



5. Bison priscus. 



6. Cerviis clactoniensis (Browni). 



7. elaphus. 



8. tarandus. 



III. Caenivoea. 



9. Ursus ferox priscus ? ( C7^ priscus). 

 TV. Peoboscidea. 



10. Elephas prhnigenius. 



1. Mhinoceros hemitoecJius. — The only distinguishable relic of Hki- 

 noceros is a nearly entire left ulna, whose form and dimensions agree 

 precisely with those of Rhinoceros hemitoechus from the ILford gravel, of
