inhabitants of the present steppes beyond the 

 Volga. 1 



* Their existence was now and again endangered 

 by a few isolated lions, also by wolves, whereas 

 hyenas (remains of which are not unfrequently 

 met with at Westeregeln) probably seized only the 

 carcases and scarcely ventured to attack the live 

 horses. 



' The worst enemy of the Diluvial horse was 

 man. We know by numberless investigations, that 

 the human inhabitants of Central and Western 

 Europe in those days lived almost entirely upon 

 the hunting of horses ; the bones and teeth very 

 probably the skins, hair, and sinews also were made 

 use of iii a variety of ways.' Nehring, whom we 

 have been quoting, goes on to say how all this was 

 done, what proofs we have of the occasional visit 

 of nomadic tribes to certain localities, and how a 

 regular system of breeding arose gradually from 

 single attempts, and then adds : 



* Those of my readers who are accessible to 

 scientific proofs will, I hope, find my detailed com- 

 parisons sufficient to convince them that an essen- 

 tial portion of our so-called heavy (common) horses 

 must be traced back to the heavy, thick-boned 

 Diluvial horse.'
