The very brilliant results that have been obtained in certain parts of the world in the eradication of malaria by consistent campaigns against the mosquito are probably the direct result of the fact that another campaign, of equal promise, has been sadly neglected in other parts, where, by reason of soil conditions, we cannot expect to be able to eradicate, or even materially to reduce, the anopheles. I refer to the possibilities of a campaign against the sexual forms of the plasmodia in man.
The question arises, are we content to wait for the development of certain of our agricultural lands before ridding ourselves of a disease the economic loss from which is so tremendous, and a loss which, in addition to the heavy penalties imposed by death and depreciation of earning power, is actually in itself a heavy barrier to the development of these lands?
