eminently fitted for, as they carried it out with
consummate skill and success, which the sale
in 1819 demonstrated. They seemed to have
intuitively grasped the physiological law enun-
ciated by Darwin a hundred years after, “that
given an equal amount of pureness of blood, the
male animal possesses a greater amount of ac-
cumulated variation in a given direction than
the female.”

“These variations afe at first artificial, but
after accumulating them for a length of time


they become typified, and constitute a distinct
variety or breed.”

It is remarkable that the elder B. Tomkins
first observed the variation in the direction he
desired in two females, and he and his son
afterwards conserved it more particularly in the
males.
