74 TRICILOLOGIA MAMMALIUM ; 
This is in accordance with the general laws of hybridisin, where the offsprings some- 
times hold an imperfect intermediate place between both species, and at others they pre- 
ponderate to one side. Where the progeny hold an intermediate place and they are bred 
together only, they gradually become less and less capable of reproduction, and after a few 
generations the race runs out. Where the constitutional energy of one parent outweighs 
that of the other, or the progeny is bred towards one side only, they pass over to that side, 
and the race becomes apparently extinct.
