LARGE FOSSIL HIPPOPOTAMUS. 401 
ganic remains from Chatham, any more than those from 
Chartham, having appertained to a ‘“‘river or sea bred 
creature.” The genus of land-quadrupeds, to which these 
fossils actually belonged, is nevertheless, at the present 
day, as much confined to the tropics as is the Hippo- 
potamus. 
No long time elapsed before true Hippopotamic remains 
were discovered in the same deposits which had yielded 
the bones and teeth of Rhinoceroses, It was most proba- 
bly from fresh-water marl that the entire skull of the Hip- 
popotamus was obtained, which is stated in Lee’s ‘ Natural 
History of Lancashire’ to have been found in that county 
under a peat-bog, and from which work Dr. Buckland 
has copied the figure given in plate xxii, fig. 5 of the 
‘Reliquie Diluviane.’ From the indication of the second 
premolar in this figure we may, I think, discern the 
greater separation of that tooth from the third premolar, 
which forms one of the marks of distinction between the 
fossil and recent Hippopotamus. 
Mr. Parkinson, in the third volume of his ‘ Organic 
Remains,’ 4to., 1811, p. 375, treating of the Hippopo- 
tamus, says, “In my visits to Walton, in Essex, I have 
been successful in obtaining some remains of this animal.” 
These fossils are now in the Museum of the Royal Col- 
lege of Surgeons, and are referable to the extinct species 
subsequently determined by Cuvier in the second edition 
of the ‘Ossemens Fossiles, under the name of Hippopo- 
tamus major. The first specimen, cited by Mr. Parkin- 
son as “an incisor of the right side of the lower jaw,” 
is the great median incisor, which, when entire, must 
have been eighteen inches in length. It has lost much 
of its original animal matter, and is considerably decom- 
posed. This tooth may be distinguished from the straight
