FOSSIL HORSE. 



391 



John Thompson, Esq., of Belfast. In sinking a well near 

 Downpatrick, in the county of Down, two teeth were 

 found in a stratum of gravel far below the present surface. 

 A tooth was found at Newry under similar circumstances. 

 In the county of Antrim teeth of the Horse have been 

 found four feet below the surface in drift gravel near 

 Belfast, and at the bottom of a turf-bog near Brough- 

 shane. 



The more common species of fossil Horse from the drift 

 formations and ossiferous caverns, which differs from the 

 existing domestic Horse in its larger proportional head and 

 jaws, resembling in that respect the Wild Horse, but 

 apparently differing in the transversely narrower form of 

 certain molar teeth, may continue to be conveniently 

 indicated by the name of Equus fossilis, the Latin synonyme 

 of the ' cheval fossile ' of Cuvier.
