and Hippopotamus, have been found in coarse gravelly drift 
with overlying marl and clay in the valley of the Severn, at 
Fleet’s bank near Sandlin. Marine shells occur in the 
coarse drift, and freshwater shells in the superficial fluvia- 
tile deposits. 
Mr. Strickland found remains of the Mammoth associat- 
ed with Hippopotamus, Urus, &c., in the valley of the 
Avon, in apparently a local fluviatile drift, containing land 
and freshwater shells: this geologist supposes that after 
those parts of Worcestershire and Warwickshire had been 
long under the sea, an elevation of some hundred feet con- 
verted them into dry land, and that a river or chain of lakes 
then descending from the north-east, re-arranged much of 
the gravel of the great northern glacial drift, disposing it in 
thin strata and imbedding in it the shells of mollusks and 
the bones of the extinct quadrupeds.* 
In the centre of England, Dr. Buckland notices the oe- 
currence of the Mammoth at Trentham in Staffordshire, in 
different parts of Northamptonshire, and at Newnham and 
Lawford, near Rugby in Warwickshire; there the Mam- 
moth’s bones lay by the side of those of the Rhinoceros and 
Hyeena. 
Mammoth-fossils occur at Middleton in the Yorkshire 
Wolds, in Brandsburton gravel-hills, and at Overton near 
York. Remains of the Mammoth are noticed by the Rev. 
Vernon Harcourt, F.R.S. and Professor Phillips, as haying 
been found associated with the great Cave Tiger, Rhino- 
ceros, Aurochs, Deer, &e., in blue marl, beneath strata of 
gravel and sand at Bielbecks, near North Cliff, Yorkshire. 
Tusks of the Mammoth, valuable from the condition of the 
ivory, have been discovered at Atwick, near Hornsea,in the 
same county.
