patient against this occurrence: in most cases it will be sufficient to keep the room moderately cool, and ensure a due degree of ventilation; but where the uterus has shown a disposition to relax, we know of nothing which guards the patient so effectually against hæmorrhage after labour, and enables us to leave her with so much confidence, as putting the child to her breast. The sympathetic connexion between the breast and the uterus is now well known; nor are there any means so certain of producing permanent uterine contraction as this natural act: it is a duty which nature instinctively prompts the mother to perform, not only for the preservation of her child, but for the safety of herself. We, therefore, make it a rule, whenever the patient intends to suckle her child (a duty which is performed more frequently now than it was a few years ago,) to have it put to the breast before quitting the house: the first excitement of the mother's feelings towards her offspring is a favourable moment for the performance of this act, the erectile tissue of the nipple becomes turgid, the child takes the breast with ease, and the effect upon the uterus is not less certain than complete; even if the child sucks fairly well for only five minutes we feel satisfied, for we cannot call to mind a single case of hæmorrhage after the effects of this operation. _Lactation._ When the wet clothing has been removed, and fresh linen substituted, the patient should be left to enjoy perfect quiet both of body and mind, in order that she may have some sleep, for "the refreshment of sleep seems to be the most powerful natural means of inducing full contraction of the uterus."[72] After this, the child should be placed at her side, in order that it may enjoy the warmth of her body, and make another trial of taking the breast. That new-born animals are not able to maintain a sufficient degree of warmth, is seen by the care with which a bird shelters her young beneath her wings, and by the manner in which kittens, puppies, &c. crawl close to the mother's abdomen to enjoy that degree of heat which of themselves they are unable to produce. Dr. Edwards has shown that the animal heat of a new-born infant is several degrees below that of the adult: the mother's breast is, therefore, the natural place for it, where it can not only enjoy the necessary warmth, but take that nourishment which has been destined for its support at this early period. A child is capable of sucking the moment it is born; indeed, we would say, better at this moment than later, for the power of instinct in it is fully as great as in other animals; whereas, if not put to the breast soon after birth, but fed instead, it quickly loses it. A vigorous healthy child immediately seeks its mother's breast, and if it does not find it, sucks at every thing which touches its mouth, even its own little hand or finger when presented to it: so strong is this instinct, that, on
