that there was necessarily an accumulation 

 of energy by the parents to produce a 2 : 10 

 trotter, as those parents may have worked 

 only enough to have preserved from dissipa- 

 tion that which they inherited, and that 

 inheritance may have been enough to have 

 furnished a foundation upon which 2 : io 

 quality could be built. What cannot exist, 

 however, is an animal of 2 : io quality com- 

 ing from parents and grandparents which 

 permitted more energy to dissipate than they 

 accumulated up to the time they reproduced. 

 To assume that such an animal as that could 

 exist is to assume that energy can be con- 

 centrated without the performance of work 

 to produce such concentration, and to find 

 such an animal would be to overthrow the 

 established doctrine of energy. 



The term "2 : 10 trotter" is used to repre- 

 sent an animal with an unusual quantity of 

 energy at a high potential, and not either 

 alone. A large animal may have a large 

 amount of energy by reason of its bulk, and 

 not much be available for work because of
