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, &e., are obtained in such abundance. 
I have met with some satisfactory instances of the asso- 
Fig. 174. ciation of fossil remains of a species of 
Hog with those of the Mammoth im 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 
Last lower molar, 
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.
