of the peridotiles, and even from petrological literature, 

 unless it be retained for this remarkable type of breccia. 

 Boulders, such as we have described, might be expected 

 to occur at the base of the sedimentary series, in proximity 

 to a crystalline floor. The Karoo beds in South Africa, 

 as is well known, are underlain in many places by a coarse 

 conglomerate of considerable thickness and great extent, 

 called the Dwyka conglomerate, which is supposed to be 

 Permian or Permo-carboniferous in age. It crops out 

 from beneath the Karoo beds at no great distance from 

 the diamond-bearing district, and very probably extends 

 beneath it. If this deposit has supplied the boulders, the 

 date of the genesis of the diamond is carried back, at the 

 very least, to Paheozoic ages, and possibly to a still earlier 

 era in the earth's history.
