WALTON : SOME NEW SECTIONS IN THE HESSLE GRAVELS. 403 
Both the chalk and flint are sharp and angular ; they show hardly any 
signs of the action of water; such roundings of the edges as is seen on 
the soft chalk fragments might easily be accounted for by the perco- 
lation of water from the surface. These facts seem to indicate that 
these gravels were formed in some other way than under water, and 
are in this respect, and also in the absence of foreign boulders, quite 
different from any of the other gravels of South-east Yorkshire. 
Mammalian Remains. 
Mammalian bones have been found in these pits in the gravel. 
Most of them have been found in the bed of clayey gravel and sand, 
just below the principal stratum of sand and at a depth of 20-24 feet 
from the surface. They were not all together, but were scattered over 
the whole length of the pit. They have been examined by Mr. 
Platnauer, of York Museum, who refers them to the horse, Equus 
caballus, and the ox. There are not many places where mammalian 
bones are found in gravel and covered by boulder clay, their exact 
record is therefore a matter of some importance. 
The following table shows what bones have been found and the 
particulars.
