 pits and of accumulations of chips heaped up around them.* Many of 

 the specimens closely resemble in shajie and size the " hatchets " of the 

 European drift, which occur associated with the remains of extinct ani- 

 mals (Fig. 53 represents a common form. The original belonged to a 

 regular deposit of about fifteen hundred specimens, which was discovered
