2 14 THE ANTIQUITY OF MAN 
lOO-foot terrace, M, Rutot recognises deposits which 
belong to the very beginning of the Pleistocene period. 
The deepest stratum of the terrace ^ may thus be older 
than the chalky boulder clay. But the upper strata of 
the terrace are certainly more recent than the chalky 
boulder clay, for in and under that deposit Mr Reid 
Moir has discovered worked flints which belong to a 
much more primitive culture than the Chellean — more 
primitive than even the Strepyan, which preceded the 
Chellean. There can be no doubt, therefore, that human 
remains lying in or under a bed of undisturbed, chalky 
boulder clay belong to a much earlier phase of the 
Pleistocene period than any yet discovered in the loo- 
foot terrace. 
The circumstances attending the finding of a human 
skeleton under a stratum of chalky boulder clay I will 
give in the words of the discoverer, Mr J. Reid Moir:"^ — 
" About a mile to the north of Ipswich, on the 
estate of Mrs W. N. Fonnereau, is situated the 
brickfield of Messrs Bolton and Laughlin, which is 
famous to geologists for the various deposits which 
have been exposed by the excavation of the London 
clay for brickmaking. These deposits, which are 
given in descending order, are : — 
Chalky boulder clay. 
Middle glacial sand and gravel. 
Decalcified red crag. 
London clay. 
Woolwich and Reading beds. 
" This brickfield is about ten minutes' walk from 
my house, and for the past six years I have been in 
the habit of visiting it on an average three times a 
week, and searching for flint implements in the beds 
above the London clay. It will thus be seen that 1
