the Acheulean period occurred long after the time of the 
major glaciation ; a valley had been cut to a depth of at 
least 50 feet and filled up again. In the interval between 
the formation of the boulder clay and the brick earth the 
climate had changed at least twice. We have seen, from 
the formation of the 100-foot terrace, that the Acheulean 
period is very remote from our day ; at Hoxne we see 
that the major glaciation was equally distant from the 
Acheulean period. 
Returning now to the pit at Bury St Edmunds, we

cannot have any doubt that the brick earth, in which the 
fragment of skull was found, is of the same age and 
formed in the same way as the brick earth at Hoxne 
(fig. 60). They are dated by the later type of Acheulean 
implements. The fragment itself, which is preserved in 
the Moyses Hall Museum at Bury St Edmunds, still 
shows, in its interstices, particles of red brick earth. It 
is stained a light reddish-brown. When struck, it has 
the resonance of porcelain. The freshly fractured surface 
has the colour of chalk, except that the spaces in the 
bone are tinged from the brick earth. The edges of 
the fragment are brown and rounded. It is evident.
