of the horse may represent a Pleistocene variety, but the 
parts discovered are not sufficient to make the identifica- 
tion certain. 
The corresponding terrace on the opposite or eastern 
side of the Medway valley, a counterpart of the Hailing 
terrace, yields abundant remains of Pleistocene animals 
(fig, 30A). In the opinion of Mr A. S. Kennard, who 
must be regarded as one of our highest authorities 
on the age and nature of English valley deposits, 
the brick earths of the Hailing terrace do belong to the 
Pleistocene period. All the evidence, then, if not 
definitely proving, at least gives us a very high degree 
of assurance in regarding the Hailing man as of the 
Aurignacian age. 
In our survey of Neolithic man in England, the Tilbury 
skeleton represented the most remote in point of time. 
That skeleton lay 34 feet beneath the submerged marsh 
surface in the adjoining Thames valley. The Hailing 
man lay in a deposit of brick earth which rises 7 feet 
above the level of the marshy floor of the Medway. What 
were the changes which occurred in the neighbouring 
valleys of the Medway and Thames between the time of 
the Tilbury and Hailing men ? In the first place, we 
must examine, as Mr W. H. Cook and Mr J. A. 
Bullbrook have done,^ the nature and formation of the 
Hailing terrace. We have already seen that there are at 
least nine distinct strata in the terrace. Each of these 
denotes a phase in the action of the Medway — its condition 
of flood, the nature of the debris it was scouring off the 
face of the Weald and depositing on its bank at Hailing. 
It is also apparent that in order to have the strata deposited 
one above the other, either the waters of the Medway 
came down in greater and greater volume, or, as is more 
likely to have been the case, the land was sinking at the 
time the terrace was being formed. There was then in 
operation a process of submergence, with filling up of the 
valley. The subsidence could not have been continuous, 
for under the fourth deposit from the top is the old land
