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.
