Two cautions, however, have to be borne in mind with reference to both of these indications of disease. The first is, that the glands in the groin may be enlarged from mere irritation, independent of actual disease communicated to them from the glands inside. If, however, you find the glands at the corner of the lower jaw and those on either side of the neck enlarged too, you are then driven to the conclusion that the glands in the groin are enlarged not from mere local irritation, but from general disease, and that consumption is its cause.

Again, the superficial veins of the belly may be enlarged from any cause which interferes with the proper circulation through the vessels inside. Hence they are often enlarged in grown people in dropsy, and hence too in infants and young children from flatulent distension of the bowels. But in this case the other signs of consumption are wanting; the emaciation, the cough, the increase of evening temperature, and the enlargement of the glands, are all absent.

Sometimes we meet with instances where the child does not digest its food, does not thrive, does not gain flesh, never passes healthy evacuations, at length wastes, loses strength, and dies, without having had any of the signs which I have pointed out as indicative of consumptive disease, and in fact without having suffered from it. Now, these cases are connected with imperfect performance of the function of the liver, and sometimes with an imperfection of its structure. Before birth the functions of the liver are not called into action in the same way nor to the same degree as afterwards, and its structure differs in this respect that it contains a larger amount of fat and a smaller proportion of bile-secreting cells than afterwards. It sometimes happens from causes which we do not understand that the liver structure not only does not undergo that higher development which should take place, but that the fat cells increase at the expense of the bile cells. In these circumstances the food is ill-digested and the health is much impaired, and at last wasting takes place to as great a degree as in the case of consumption, only there are no cough, no glandular enlargement, no big superficial veins, no increased temperature, while on a careful examination the doctor will seldom fail to find the rounded edge of the enlarged liver coming lower down than natural. In these cases too there is a disposition to convulsive affections, and to that peculiar form of convulsion called spasmodic croup, concerning which I shall have something to say later on.

In its less serious form this is both a more frequent and a less grave condition than consumption, and its existence explains to a great degree those cases in which young children have failed to be nourished by the milk food which commonly suits their tender age, but have improved on beef-tea, raw meat or its juice, and food entirely destitute of saccharine matter.

In cases where there is reason to apprehend consumptive disease, the skill and resources of the doctor will often be heavily taxed to meet each difficulty as it arises. A good wet-nurse, or, in default of her, asses' milk, with the addition of cream to supply the butter in which the asses' milk is deficient, a couple of teaspoonfuls of raw meat juice in the course of every twenty-four hours, much care in the introduction of farinaceous substances into the diet, and cod-liver oil twice a day, beginning with ten drops and gradually increasing the dose to a teaspoonful, are all that the mother herself can do. When the cod-liver oil is not borne by the stomach, or when—which, however, is not often the case—the child refuses to take it, glycerine may be substituted for it, though it must be owned that it is a very poor and inefficient substitute. The inunction of cod-liver oil is in any case not to be had recourse to; it makes the child unpleasant to itself and loathsome to others, while the power of the skin to absorb oily matters is far too limited to be worth taking into account.

Vomiting, though by no means a prominent symptom of either of the two very grave conditions of which I have been speaking just now, is yet a very common attendant on all disorders of digestion in early life. It is indeed much more frequent in the infant than in the adult, and the greater irritability of the stomach continues even after the first few months of existence are past, and does not completely cease during the early years of childhood. In every case of vomiting in childhood, therefore, the first question to set at rest is whether it depends on disorder of the digestive system, or whether it heralds the onset of one of the eruptive fevers, or of inflammation of the chest, or of affection of the brain; and in determining this all the directions given when I was speaking of the general symptoms of disease are to be carefully studied. Vomiting often accompanies infantile diarrhœa, even when the food taken cannot be regarded as its occasion; and now and then the stomach, with no obvious exciting cause, suddenly becomes too irritable to retain any food, and this indeed may be the case even though attended by few or no other indications of intestinal disorder. The child in such cases seems still anxious for the breast; but so great is the irritability of the stomach that the milk is either thrown up unchanged immediately after it has been swallowed, or it is retained only for a few minutes, and is then rejected in a curdled state; while each application of the child to the breast is followed by the same result. It will generally be found, when this accident takes place in the previously healthy child of a healthy mother, that it has been occasioned by some act of indiscretion on the part of its mother or nurse. She perhaps has been absent from her nursling longer than usual, and returning tired from a long walk or from some fatiguing occupation, has at once offered it the breast, and allowed it to suck abundantly; or the infant has been roused from sleep before its customary hour, or it has been over-excited or over-wearied at play, or in hot weather has been carried about in the sun without proper protection from its rays.

The infant in whom from any of these causes vomiting has come on, must at once be taken from the breast, and for a couple of hours neither food nor medicine should be given to it. It may then be offered a teaspoonful of cold water; and should the stomach retain this, one or two spoonfuls may be given in the course of the next half-hour. If this is not rejected, a little isinglass may be dissolved in the water, which must still be given by a teaspoonful at a time, frequently repeated; or cold barley-water may be given in the same manner. In eight or ten hours, if no return of vomiting takes place, the experiment may be tried of giving the child its mother's milk, or cows' milk diluted with water, in small quantities from a teaspoon. If the food thus given does not occasion sickness, the infant may in from twelve to twenty-four hours be restored to the breast: with the precaution, however, of allowing it to suck only very small quantities at a time, lest, the stomach being overloaded, the vomiting should again be produced.

In many instances when the sickness has arisen from some accidental cause, such as those above referred to, the adoption of these precautions will suffice to restore the child's health. If, however, other signs of disorder of the stomach or bowels have preceded the sickness, or are associated with it, medicine cannot be wholly dispensed with, and the advice of the doctor must be sought for. Very likely in addition to directing the rules above laid down to be attended to, he may lay a tiny dose of calomel, as a quarter, half or a whole grain on the tongue, which often has a wonderful influence in arresting sickness; while he may further put a small poultice not much bigger than a crown piece, made half of mustard, half of flour, on the pit of the stomach for a few minutes, and may give the child a little saline, with a grain or two of carbonate of soda, and perhaps a drop of prussic acid. These, however, are not remedies to be employed by the mother, but must be prescribed, and their effect watched by the medical attendant.

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 diarrhœa, 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 fœtid 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 child is brought up entirely at the breast, the motions are usually liquid, of a very pale yellow colour, often extremely offensive, and contain shreds of curdled milk, which not having been digested within the stomach, pass unchanged through the whole track of the bowels. In many instances, however, the infant having been observed not to thrive at the breast, arrowroot or other farinaceous food is given to it, which the stomach is wholly unable to digest, and which gives to the motions the appearance of putty or pipe-clay, besmeared more or less abundantly with slime or mucus. The evacuations are often parti-coloured, and sometimes one or two unhealthy motions are followed by others which appear perfectly natural; while attacks of diarrhœa often come on, and the matters discharged are then watery, of a dark dirty green colour, and exceedingly offensive.
