Animal remains are rather abundant in these deposits ; a 

 good collection being in the possession of Mr. Grantham, of 

 Crayford. In which are the following: —

teeth, tusk, &c. Lion? Ditto and jaw, &c. 



Irish Elk ? Horn. Horse ; Various bones.

The mammaliferous deposit at Grays has been described in 

 Loudon's 'Mag. Nat. Hist.' for 1836, as also that at Copford 

 by Mr. Brown, and at Stutton by Mr. Wood, in the same 

 work for 1834. 



Fossil bones are found off the coast of Walton and Har- 

 wich ; and on the Kentish side are constantly being dredged 

 up at Hearne Bay : they occur also in the same county along 

 the valleys of the Stour and Medway.* 



The mineral character of the deposit at the various locali- 

 ties, especially where containing shells, is very similar. The 

 bones, though dispersed through the whole, are more nume- 

 rous in the bed of sand, which is either interstratified with, 

 or underlies the brick-earth. This bed of sand is also of con- 

 stant occurrence in other places yielding brick-earth along the 

 valley where mammalian remains have not yet been noticed.
