For such we have devised a way of preserving the breeds pure by means of pedigrees, recorded in studbooks, herdbooks, or other publica- tions. Along with the pedigrees, for some breeds we record the excellencies of the individual animal thus registered ; and we have also devised ideal " scales of points " of especial excellence to be recorded.
