tity of available energy, or available energy 

 at a much higher potential, than existed in 

 any of its ancestors at the same age, two 

 or three generations previously. For example, 

 a horse is capable of trotting very much faster 

 than any ancestor, a cow is capable of pro- 

 ducing a greater quantity of milk in a given 

 time than either granddam, and a man has 

 mental capabilities far beyond those of the 

 parents of either his father or his mother. 

 Or, to be more specific, take a modern trotting 

 horse which is able to trot a mile in Jess than 

 2 : 10. That horse had two parents, four 

 grandparents, and eight great-grandparents. 

 As far as "blood" is concerned, that horse is 

 a composite of those great-grandparents, and 

 he is largely such as far as his physical struc- 

 ture is concerned. But his available energy, 

 at say five years of age, is not similarly a 

 composite or average of the energy of his 

 great-grandparents at the same age. Not 

 only is his available energy greater than the 

 average of those ancestors, but it is greater 

 than that of any one of them.
