Energy in Animals 51 



will be very similar to those constructed for 

 heat and electricity. While we do not have 

 formulas for the rate of concentration and 

 dissipation of energy which we can apply 

 to the different animals in a pedigree, still, 

 by observing the principles involved and 

 taking cases so pronounced and so well re- 

 corded that there is no excuse for overlook- 

 ing what occurred, we can determine the 

 main facts of how energy is accumulated 

 through the generations. 



In applying these principles to the animals 

 in the pedigree of a trotter for the purpose of 

 determining whether energy accumulated in 

 a previous generation is transmitted to the 

 next, we look first into the dynamic condi- 

 tion of the sire. We estimate the volume and 

 potential of his energy from the work he did. 

 If the trotter is a stallion, we look at the 

 dynamic condition of the sire as it existed 

 a short time before reproduction. If the 

 trotter is a mare or gelding, we look at the 

 condition as it existed in the sire at three 

 years of age. In determining this dynamic
