What a strange anomaly it would be if a directly opposite rule were to prevail when we go down one step lower in the series, namely to the individuals of the same species, and these had not been, at least at first, confined to some one region!
Zein anomalia arraroa litzatekeen, seriean maila bat beherago egin eta espezie bereko banakoetara iristean, alderantzizko araua nagusi izatea eta banako horiek, hasieran bederen, eskualde bakar batera mugaturik ez direla egon aurkitzea!
