258 I'ROBOSCIDIA. 



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 oc- 

 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 

 Hyaena. 



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 having 

 been found associated with the great Cave Tiger, Rhino- 

 ceros, Aurochs, Deer, &c., 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.
