RELICS OF MAN 25 



in this Drift in other situations, but the above are 

 enough for the general argument. 



Human remains are exceedingly rare, but stone 

 implements fashioned by Palaeolithic Man have been 

 discovered in several places. One of the best in- 

 stances is the flint implement of the lance-head 

 Amiens type found at Portslade, near Brighton, at 

 a depth of 15 feet from the surface in a bed the 

 equivalent of the Brighton Elephant Bed. It is now 

 in the Brighton Museum. 



The Ossiferous Fissures. Another form under 

 which the Eubble-drift occurs is that of a breccia 

 in rock-fissures. This breccia occasionally contains 

 Mammalian remains, whence the term of " Ossiferous 

 Fissures." These fissures or rents have been filled up 

 to the level of the ground with angular fragments of 

 the adjacent rocks embedded in a red earth or clay, 

 often cemented by calcite. In England they are 

 common only in the limestone rocks of the neighbour- 

 hood of Plymouth. The fissures are of variable width, 

 are sometimes vertical, and at other times inclined at 

 various angles, and the sides are rough and irregular. 

 The rock fragments, which are angular and sharp, are 

 of all sizes. The bones are rarely perfect, and are 

 often broken into innumerable fragments. No skeleton 

 is found entire. 1 The separate bones, in fact, have been 

 dispersed in the most irregular manner, and without 

 any bearing to their relative position in the skeleton. 



1 Judging however from the occasional position of the bones, 

 it would seem that entire limbs with the ligament attached were 

 sometimes washed in.
