nidations of gravel, clay, sand, &c. Associated with the 
remains discovered in the parish of Burfield, in Wor- 
cestershire, my friend Mr. Strickland found a number of 
shells, of which he determined twenty-four species (five 
terrestial and nineteen fresh water) ; of these only three 
appeared to be extinct species ; all the others are now 
existing, and indigenous to Britain, a proof sufficient, if no 
others could be cited, that this quadruped was associated 
with them in life as well as after death, and not brought 
from tropical regions, as also of the comparatively recent 
date of the animal's destruction. Sir C. Lyell, in alluding 
to this discovery, observes, — " The Hippopotamus is now 
only met with in rivers where the temperature of the water 
is warm and nearly uniform ; but the great fossil species 
certainly inhabited England when the testacea of our country 
were nearly the same as those now existing, and when the 
climate cannot be supposed to have been very hot." 
In Yorkshire, the bones of the Hippopotamus have been 
found in only three localities, — in the cave at Kirkdale, near 
Pickering, where six molar teeth and a few fragments of 
incisors and canine teeth were discovered ; at Overton, near 
York, a single molar tooth ; and in the present instance, 
which is the first on record in the West Riding ; and it is an 
interesting circumstance, as I have already stated, that these 
remains indicate the quadrupeds to have been of different 
ages — both mature and immature, and especially when taken 
in connexion with those from the Kirkdale Cave, afford pre- 
sumptive evidence of the aboriginal nature of the animals, 
which would not have been so satisfactory if only a fragment 
or two of a single individual had been discovered, as these 
might have been drifted from a neighbouring county or 
distant region, which is not so probable when both old and 
young individuals are found associated in different parts of 
the same county, and under different circumstances. Dr. 
Buckland figures two permanent molar teeth of a young
