red crag. These mammaliferous beds have been proved by 

 Mr. Lyell to be older than the fluvio-marine or Norwich 

 crag, in which remains of the Mastodon, Rhinoceros and 

 Horse have been discovered ; and still older than the fresh- 

 water Pleistocene deposits from which the remains of the 

 Mammoth, Rhinoceros, &c., are obtained in such abundance. 

 I have met with some satisfactory instances of the asso- 

 ciation of fossil remains of a species of 

 Hog with those of the Mammoth in the 

 newer pliocene freshwater formations of 

 England. 



In the collection of Mr. Wickham 

 Flower there are good specimens of the 

 teeth of the Hog (molars, and a long and 

 sharp tusk), which were taken from the 

 brick-earth at Grays in Essex, twenty 

 feet below the present surface ; these 

 teeth were associated with teeth and bones

Hog ; nat. size. of a Deer, and portions of dark charred 

 wood. Mr. Brown of Stanway has likewise some fossil 

 remains of a young specimen of Sus from the freshwater 

 deposits at Grays, which contained remains of the Mam- 

 moth and Rhinoceros.
