In the human subject the process of teething begins late, between the seventh and the ninth month, and goes on slowly: the first grinding teeth are seldom cut before the beginning of the second year, and teething is not finished until after its end. Until teething has begun the child ought to live exclusively on the food which nature provides; for until that time the internal organs have not become fitted to digest other sustenance, and the infant deprived of this too often languishes and dies. To get from other food the necessary amount of nourishment, that food has to be taken in larger quantities, and, from the difficulty in digesting it, needs to remain longer in the stomach than the mother's milk. One of the results of the indigestibility of the food is that the child is often sick, the stomach getting rid of a part of that food which it is unable to turn to any useful purpose; and so far well. But the innutritious substances do not relieve the sense of hunger. The child cries in discomfort, and more is given to it, and by degrees the over-distended stomach becomes permanently dilated, and holds a larger quantity than it was originally meant to contain. The undigested mass passes into a state of fermentation, and the infant's breath becomes sour and offensive, it suffers from wind and acid eructations, and nurses sometimes express surprise that the child does not thrive since it is always hungry. While some of the food is got rid of by vomiting, some passes into the intestines, and there becomes putrid, as the horribly offensive evacuations prove. They come away, large and solid and white, for the secretion of the bile is inadequate to complete that second digestion which should take place in the intestines; or else the irritation which they excite occasions diarrh[oe]a--a green putty-like matter comes away mixed with a profuse watery discharge. What wonder is it that in such circumstances the body should waste most rapidly; for it is forced from its own tissues to supply those elements essential to the maintenance of life, which its food contains in far too scanty a proportion. Every organ of the body contributes to the general support, and life is thus prolonged, if no kind disease curtail it, until each member has furnished all that it can spare, and then death takes place from starvation, its approach having been slower, but the suffering which preceded it not therefore less, than if all food had been withheld. Do not suppose that in this description I have been painting too dark a picture, or that children who die thus have been exceptionally weak, and so under the acknowledged difficulties of hand-feeding at length became consumptive. They do not die of consumption, and in a large number of instances their bodies show no trace of consumptive disease, but present appearances characteristic of this condition of starvation, and of this only.
