 started in life in a small way, and the first of 

 the line, the Hyracotherium, was " a little an-

 he scampered over Tertiary rocks," in the age 

 called Eocene, because it was the morning of 

 life for the great group of mammals whose cul-

 creature, apparently far less likely to succeed 

 in life's race than his bulky competitors, and
