 Europe, as far to the north-west as Yorkshire. Its bones 

 and teeth, found in northern Siberia and in Eschscholtz 

 Bay, and other localities in North America, prove that in 

 former times the herds, now rapidly being destroyed by

 zone, the most important is the grisly bear (Fig. 20), 

 the fossil remains of which, according to Professor Busk, 

 are met with from Gibraltar, in the south-west, as far 

 to the north as Britain and Belgium. At the present 

 time the brown and grisly bears inhabit the same regions 

 in North America, and we need therefore feel no surprise 

 that they should be found together in the Pleistocene
