Now and then infants are born with consumptive disease. In that case the lungs are always affected; and the symptoms of fever, cough, and wasting usually show themselves within the first three or four months, and the infants almost invariably die within the year. Now and then, however, an infant thus affected may continue apparently in good health for a few months, and then be suddenly attacked by symptoms of acute inflammation or of severe bronchitis which prove rapidly fatal; and it may be found after death that the acute attack destroyed life because the lungs were already the seat of extensive consumptive disease. No infant in whose mother's family a predisposition to consumption exists ought to be nursed by its mother, but by a healthy wet nurse; or, if that is impossible, it should be brought up on a milk diet, with but a small admixture of farinaceous food. There is a form of very rapid, or so-called galloping consumption, which is seldom observed before the age of seven years; generally two or three years later. Its symptoms so closely resemble those of typhoid fever, that it may readily be mistaken for it. I refer to it in order to say that the doctor who mistakes the one for the other can scarcely be regarded as blameworthy; and the mistake is of the less importance since the treatment applicable to the one case would do no harm in the other. I have already noticed the connection between water on the brain and consumption. It is indeed nothing else than inflammation excited by the presence of the deposit of consumptive matter in the brain or its membranes.
