Sickness, indeed, is not always a solitary symptom unattended by other evidences of disordered digestion, but is sometimes associated with signs of its general impairment, and this may be so serious as to lead to great loss of flesh, and even to end in endangering life. In many instances, however, the child does not lose much flesh though it digests ill, and its symptoms would be troublesome rather than alarming, if it were not that they are often the signs of an unhealthy constitution, out of which in the course of a few months consumption is not infrequently developed. Long-continued indigestion in the infant always warrants anxiety on the part of the parent. In some of these cases there is complete loss of appetite, the infant caring neither for the breast nor for any other food. It loses the look of health and grows pale and languid, though it may not have any special disorder either of the stomach or of the bowels. It sucks but seldom and is soon satisfied, and even of the small quantity taken, a portion is often regurgitated almost immediately. This state of things is sometimes brought on by a mother's over-anxious care, who, fearful of her infant taking cold, keeps it in a room too hot or too imperfectly ventilated. It follows, also, in delicate infants on attacks of catarrh or of diarrh[oe]a, but it is then for the most part a passing evil which time will cure. In the majority of cases, however, the loss of appetite is associated with evidence of the stomach's inability to digest even the small quantity of food taken, and the bowels are irregular in their action, as well as unhealthy in their secretion. Loss of appetite, too, though a frequent is by no means a constant attendant on infantile indigestion, but is replaced sometimes by an unnatural craving, in which the child never seems so comfortable as when sucking. It sucks much, but the milk evidently does not sit well upon the stomach; for soon after sucking, the child begins to cry and appears to be in much pain until it has vomited. The rejection of the milk is followed by immediate relief; but at the same time by the desire for more food, and the child often can be pacified only by allowing it to suck again. In other cases vomiting is of much less frequent occurrence, and there is neither craving desire for food, nor much pain after sucking; but the infant is distressed by frequent acid or offensive eructations; its breath has a sour or nauseous smell, and its evacuations have a most f[oe]tid odour. The condition of the bowels that exists in connection with these different forms of indigestion is variable. In cases of simple loss of appetite, the debility of the stomach is participated in by the intestines, and constipation is of frequent occurrence, though the evacuations do not always appear unhealthy. In other instances in which the desire for food still continues, the bowels may act with due regularity, but the motions may have a very unnatural appearance. If the
