FOUND IN THE RED CLAY AT STOCKTON. 237 
larger teeth, but of the smaller one, it is only one inch in both 
diameters. 
I also exhibit, for the sake of comparison, three more teeth of 
a Horse, which I found in a sandy field called Newton Heads, 
at Norton, near Stockton, on November 5th, last, where a deep 
hole had been dug; and close to the same spot, in another hole, 
upon the same day, a fragment of a human skull. As many 
human bones have been discovered during many years past in 
the same field—which is mentioned in a paper I read to the 
sub-section ‘‘ Ethnology” of the British Association at Swansea, 
in 1848, and recorded in the Report of that year, it is supposed, 
according to local history, that a battle had taken place there 
some centuries ago; if so, the horse was probably there interred 
with his slain rider. 
These teeth do not exceed two anda half inches in length, and 
the grinding surface in all is one inch, in both of their diameters. 
And it will be seen that the external conditions of the teeth 
are very different; in the Stockton specimens they have a harder 
and a highly polished surface, which is wanting in the Norton 
teeth. 
Again, I have brought two molar teeth of the existing ordi- 
nary horse, from which it will be noticed that the long diameter 
of the grinding surface in both, is one and one-eighth inches, and 
the short diameters are seven-eighths and six-eighths—but their 
lengths are three inches, and two and three-fourths inches 
respectively. 
In the Fossil room of the British Museum I saw very recently 
some teeth of the Hquus fossilis, which corresponded apparently 
with the three Stockton specimens in their size, colour, and 
glazed appearance. 
Specimens of the Stockton fossil teeth, and of the Norton 
(Newton Heads), more modern teeth, are now deposited in the 
Museum of the Natural History Society, Newcastle.
