This over-abundant supply may be moderated and the quality improved by diminishing the quantity of drink, and by the use of preparations of iron. Fifteen drops of the muriatic tincture of iron, taken three times a day in a little sweetened water, through a glass tube, will be useful. It will lessen the amount of the milk, and make it richer. So soon as these objects are accomplished, the medicine should be discontinued; as, if taken too long, it may so much diminish the milk as to necessitate weaning. The application of a cloth, wrung out in cold water, around the nipples is also of value. It is to be removed so soon as it becomes warm, and reapplied. In those cases in which the trouble seems to be not so much an over-supply as an inability to retain the milk, the administration of tonics addressed to the nervous system, and the local use of astringents and of collodion around the nipples, will overcome the difficulty; but these remedies can only be employed successfully by the physician. And to him alone should be entrusted the use of those medicines which directly diminish the amount of milk secreted within the breasts. The expedients we have mentioned are the only ones which can be safely employed by the mother herself in this annoying affection. SCANTINESS OF MILK. Some mothers have habitually an insufficiency of milk. They are most numerous in large cities, and among working women whose daily occupations require a separation from the infant. Indigestion, and the want of a proper amount of nourishing food, cause a diminution in the quantity of milk. So also do over-feeding and gormandizing. Age lessens the secretion of milk, as has been already mentioned. Those who first bear children late in life, have less milk for them than they who begin earlier. In some cases want of milk in the breasts seems to be due to its reabsorption. In such instances it may make its appearance at distant parts. Thus, a case has been recorded of the coughing up of milk following sudden arrest of the secretion, and others in which it presented itself as an exudation in the groins.
