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 diarrh[oe]a often come on, and the matters discharged are then watery, of a dark dirty green colour, and exceedingly offensive. Children, like grown persons suffering from indigestion, often continue, as I have already said, to keep up their flesh much better than could be expected, and in many cases grow up to be strong and healthy. Still the condition is one that not merely entails much suffering on the infant, but by its continuance seriously impairs the health, and tends to develop the seeds of any constitutional predisposition to consumptive disease. In these cases there are many respects in which the mother can most efficiently second the doctor. All causes unfavourable to health must be examined into, and as far as possible removed. It must be seen that the nursery is well ventilated, and that its temperature is not too high; while it will often be found that no remedy is half so efficacious as change of air. Next, it must not be forgotten that the regurgitation of the food is due in great measure to the weakness and consequent irritability of the stomach, and care must therefore be taken not to overload it. If these two points are attended to, benefit may then be looked for from the employment of tonics, and as the general health improves the constipated condition of the bowels, so usual in these cases, will by degrees disappear; while if aperients are needed those simple remedies only should be employed of which I spoke in the first part of this book, and the use of mercurials is not to be resorted to without distinct medical order.
