In the treatment of a scanty formation of milk, one of the best measures which can be resorted to is the frequent application of the child to the breast. In addition, the flow may be increased by milking the breasts by means of the thumb and finger, suction through a tobacco-pipe, or the breast-pump, or by the use of another infant. Friction of the breasts, and forcible drawing upon the nipples, will make them sore, and so irritate them as to defeat the object in view. A change of scene, fresh air, and outdoor exercise, attention to personal cleanliness, and the improvement of the general health, all increase the quantity, and produce a favourable effect upon the quality, of the milk. A sojourn at the sea-side often promotes an abundant secretion of milk. The diet should be regulated by the condition of the constitution. By those who are weak and pale, a large proportion of meat is required. On the contrary, those who are full-blooded and corpulent should restrict the amount of their animal food, and take more exercise in the open air. Oatmeal gruel enjoys a reputation for increasing the flow of milk. A basin of it sometimes produces an immediate effect. The same is true of cow's milk. Porter or ale once or twice a day, in those with reduced systems and impaired digestion and appetite, will be found useful. Anise, fennel, and caraway-seeds, given in soup, act sometimes as stimulants upon the secretion of milk. The application of a poultice made from the pulverized leaves of the castor-oil plant is a most efficient remedy when milk fails to make its appearance in the breast in sufficient quantity after confinement. WET-NURSING BY VIRGINS, AGED WOMEN, AND MEN. As a rule, the secretion of milk is limited to one sex, and in that is confined to a short period after childbirth. But there are many cases on record of the flowing of milk in women not recently mothers, in girls before the age of puberty, in aged women, and even in individuals of the male sex. In such instances, the secretion is induced by the combined influence, acting through the nervous system, of a strong desire for its occurrence, of a fixed attention towards the mammary glands, and of suction from the nipples.
