The deduction which the compiler of these statistics reached was that 
the same law which governs in thoroughbred horses and in the trotting 
family ruled in dogs: that there is one supreme sire-power source, and but a 
few dam-power sources, the proof of the latter conclusion being that of the 
thirty dogs named in these tables nineteen trace back to six bitches— 
Merry Fan, Old Hall Vera, Pepita, Parbold Dolly, Sweet Lassie, and 
Ruby III. Astrologer traces to the dam of Charlemagne, and Wellesbourne 
Councillor to a sister to General Trefoil.
