The mammoth was not the only giant that inhabited England in the
Pliocene or Upper Tertiary period. We had also here the _Rhinoceros
tichorrhinus_, or “strongly walled about the nose,” remains of which
have been discovered in enormous quantities in the brickfields about
London. Pallas describes an entire specimen of this creature, which was
found near Yakutsk, the coldest town on the globe. Another rhinoceros,
_leptorrhinus_ (fine nose), dwelt with the elephant of Southern Europe.
In Siberia has been discovered the Elaimotherium, forming a link
between the rhinoceros and the horse.
In the days of the mammoth, we had also in England a Hippopotamus,
rather larger than the species which now inhabits the Nile. Of our
British hippopotamus some remains were dug up by the workmen in
preparing the foundations of the New Junior United Service Club-house,
in Regent-street.
