the Head of an Hippopotamus, takes occafion thence for a 
Difcourfe, wherein he endeavours to prove, That all the 
low Ground from the Eaft-Kentijh ftiore, to Romney-Marjh, 
was once under Water, and an Arm of the Sea. Publifhed, 
fince his Death, by his Brother Mr. John Somner : in whofe 
Ground thefe Bones were dig'd up $ and by whom they 
were beftowed upon this Mufieum. 
This Jaw-Bone, is only part of the far Cheek 3 about 
fifteen inches long, and feven where deepeft : yet part of 
both the ends, and the Sockets of the Teeth are broken off* 
The Orbit of the Eye, neither fo round, nor fo big, as in 
the Hippopotamus : yet the Teeth far bigger. For the bigeft 
Grinder in the Head of the Hippopotamus here preferv'd, is 
lefs than fix inches about : one of thcfe, near eight. And 
'tis much, if they belonged to that Animal, that none of 
the long Cutters which grow before (as is reprefented in 
Tab. 1 .) fhould be found with them. 
Befides, in that Skull of the faid Animal, the Orbits of the 
Eye ftand fo high, and the Forehead lies fo low, that it looks 
like a Valley between two Hills : whereas in this Bone, the 
Forehead evidently (lands higher than the Eye. The Knob 
alfo at the Corner of the Eye in this Bone, is fix times as 
big, as in the faid Skull. Although this perhaps, as well as 
the tuberoufnefs of the Bone in fome places, may be the 
effect of its lying fo long under ground 5 as if it were there- 
by a little fwell'd in thofe places : for they are more rare 
and foft, than the other,and the whole Bone, than the Skull 
of any grown Animal not bury'd. Confidering all toge- 
ther, it feems to me more likely to belong to a Rhinoceros, 
for the being whereof in this Country, we have as much 
ground to fuppofe it, as of the Hippopotamus. See Wormiuss
