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 diarrh[oe]a, 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,
