(SeeFever, Part X.) The period of active congestion which ushers in the secretion of milk proper does not lastover two days when the woman nurses her child, and somewhat longer whenshe does not. In the latter case, when there is no demand for its secretionthe milk gradually assumes the character of the original colostrum, andfinally disappears altogether. The emptying of the breast in lactation isbrought about as follows: The infant first causes an erection of the nipple sothat the first milk that enters the sinuses of the excretory duct is abstractedby the pressure and suction of its lips. The vis a iergo is then brought intoplay through reflex stimulation of the gland by the act of suction, so that an. v^t\;0/fa!(«l» ffy V.!i ^M j ^^ Fig. 914.—Regenerating Mucous Membrane ofTHE Uterus on the Sixth Day of the Puer-perium.

In a few moments after the appli-cation of the child a pain is felt in the breast and the milk is then seen tojet forth. This may often be observed simultaneously in the opposite breast,and even in both glands quite independently of the act of suction, from themer
