By way of confirma­tion of the view that this is the modus operandi one has only to point to the other seven regions shown in Figs. [49] and [50], in which the connec­tion between the pressure of harness and the produc­tion of a new pattern is beyond all doubt one of cause and effect.

Fig. 55.—Brown cart horse, examined 25th October, 1914. Whorl, feather­ing and crest (W F C) in middle line of under surface of neck begin­ning under­neath collar and proceed­ing ver­tic­al­ly up­wards for six inches.

Fig. 56.—Bright bay pony, examined 29th October, 1914. Very mus­cu­lar neck. On under surface on each side a wide curv­ing stream of hair pass­ing towards middle line and join­ing in a cen­tral upward stream end­ing above in a tuft (T).

The Proof of Transmission of Pattern.

Third.—To show that the effects produced by pressure in one genera­tion are sometimes inherited by its descendants it is necessary to examine a few examples of young horses who have never borne the yoke as yet.
