Abstract
THE discovery by Ross of the mosquito cycle made it possible for the first time to explain a host of facts in the epidemiology of malaria which otherwise were entirely inexplicable. It very soon became evident that malaria, instead of being contracted from man's general surroundings in Nature, as up to then had been supposed, was merely a special case of a man-to-man infectious disease, differing only from other infectious diseases in that an intermediate insect host was required for its transmission. That the insect host was a necessary factor did not at first presuppose any very complicated relationship in this respect. If there was no vector there would naturally be no malaria ; but other things being equal, the amount of malaria might be expected to be in proportion to the numerical prevalence of the incriminated insect.
