BOS LONGIFRONS 



HAVING driven off Bos primigenius, we ought now 

 to follow up the wild white bull that led us off 

 the scent ; but it will be more convenient to leave 

 him alone for the present and pick him up again 

 in his proper place. 



We are told by those who collect and con- 

 sider the records of the past the geologist, the 

 archaeologist, and the historian that the animals 

 that have lived in Britain and Western Europe 

 at one time and another have all migrated thither 

 from the East. Bos primigenius, who was one of 

 the early arrivals, came westward just before the 

 Pleistocene, or Glacial period "a prolonged 

 period of cold broken up by shorter periods of 

 milder climate " x and he lived through that 

 period and several sections of the next, in whose 

 elucidation the geologist and the archaeologist 

 combine. 



The earliest signs of man appear about the 

 beginning of this next period, which is conveni- 

 ently broken into sections or ages marked off
