remains of extinct Mammals, themselves bear evidence of an 

 exceedingly barbarous condition of the human species. Post- 

 Pliocene or " Palaeolithic " Man was clearly unacquainted with 

 the use of any of the metals. Not only so, but the workman-

 later tribes, who were also ignorant of the metals, and who 

 also used nothing but weapons and tools of stone.

 Pliocene period that the palaeontologist proper has to deal. 

 When we enter the " Recent " period, in which the remains of 

 Man are associated with those of existing species of Mammals, 

 we pass out of the region of pure palaeontology into the do- 

 main of the Archaeologist and the Ethnologist.
