If this deficiency exist from the earliest weeks after delivery, and it is not quickly remedied by the means presently to be pointed out, a wet-nurse must be obtained. It will be of no avail partially to nurse, and partially to feed the infant at this period and under such circumstances, for if it is not soon lost, it will only live for a few months, or a year at most, and be an object of the greatest anxiety and grief to its parent. This condition arises from the unwholesomeness of the mother's milk, united with the artificial food; for when the milk is deficient from the first, and continues so notwithstanding the means used for its increase, it is invariably unhealthy in its quality. This deficiency, however, may exist, and even at a very early period after delivery, and yet be removed. This, however, is not to be accomplished by the means too frequently resorted to; for it is the custom with many, two or three weeks after their confinement, if the supply of nourishment for the infant is scanty, to partake largely of malt liquor for its increase. Sooner or later this will be found injurious to the constitution of the mother: but how, then, is this deficiency to be obviated? Let the nurse keep but in good health, and this point gained, the milk, both as to quantity and quality, will be as ample, nutritious, and good, as can be produced by the individual. I would recommend a plain, generous, and nutritious diet; not one description of food exclusively, but, as is natural, a wholesome, mixed, animal, and vegetable diet, with or without wine or malt liquor, according to former habit; and, occasionally, where malt liquor has never been previously taken, a pint of good sound ale may be taken daily with advantage, if it agree with the stomach. Regular exercise in the open air is of the greatest importance, as it has an extraordinary influence in promoting the secretion of healthy milk. Early after leaving the lying-in room, carriage exercise, where it can be obtained, is to be preferred, to be exchanged, in a week or so, for horse exercise, or the daily walk. The tepid, or cold salt-water shower bath, should be used every morning; but if it cannot be borne, sponging the body withsalt-water must be substituted. By adopting with perseverance the foregoing plan, a breast of milk will be obtained as ample in quantity, and good in quality, as the constitution of the parent can produce, as the following case proves:
