A System of midwifery : including the diseases of pregnancy and the puerperal state . quently. aspasmodic contraction takes place independently of any special excite-ment, the result being the involuntary expulsion and loss of the well-known sympathy which subsists between the glands and otherorgans, such as the stomach and uterus, may give rise to similar phe-nomena : while that which exists between the breasts of eaeli side oftenresults in the spasmodic emptying of one gland while the child is atthe other. The lacteal vessels are lined throughout by a mucous membrane,continuous at the nipple with the common integument, and which isinvested by a tessellated epithelium. They are accompanied in theirwhole course by numerous lymphatics, which are connected intimatelywith those of the axilla and other neighboring parts. These lym-phatics are believed to take up the watery portion of the milk, and it issupposed to be by their action that frictions are beneficial in eases wherewe w isb to diminish or arrest the secretion of milk.

In the latter months of preg-nancy, the pressure of the gravid uterus tends, as Mr. Nunn has | ointedout, to increase from mechanical causes the quantity of blood in thesevessels, and thus to promote the secretion of the gland.
