If the precautions herein detailed were properly carried out, for even a few months, malaria would practically cease to exist wherever this was done, and would not recur unless individuals from other places suffering from the disease were to come into the districts where the Anopheles mosquito is present, and so give it to the gnats--to be by them recommunicated to humanity. TUBERCULOSIS. Of all the enemies of mankind, tuberculosis, in its various forms, takes the first rank. Of protean manifestations, occurring in almost every part of the body and producing diseases of the brain, of the nerves, of the bones, of the skin, and of all of the internal organs--pre-eminent is the terrible malady we call consumption, which is tuberculosis of the lungs. It has been estimated that one-seventh of all the people born into the world die as a result of this malady in some one of its various forms, and it is probable that one person out of every three dying between the ages of fifteen and sixty years, succumb to this disease. As a result of the labors of thousands of patient, self-sacrificing investigators--many of the most distinguished of whom have died of this disease while carrying on their work--the peculiarities of this affection are now fairly well understood, and if we were to apply the knowledge which we now possess in our attempts to free ourselves from its ravages, there is no question but that within a comparatively short period of time the disease would practically cease to exist.
