My duties as editor of this volume have been in one respect slight, in another more arduous. For, on the one hand, I have thought it best to leave almost unchanged Prof. Mannaberg's very comprehensive...

Our knowledge of the etiology of malaria has been enriched to such an extent in the last ten years that we may consider the disease among those the etiology of which is best known. Among the etiol...

A further fact, showing the effect of heat, is that malarial epidemics occurring about disease foci are more severe in warm than in cool summers. Moreover, during especially hot summers malaria break...

The importance of swamps in the origin of malaria has been proved many times by the disappearance of the disease on draining them. Still there are numerous examples of swamps which, on account of ...

The suspicion that malaria was caused by a living contagium has been entertained from the most ancient times and repeatedly expressed by even the oldest writers (Vitruvius, Varro, Columella). Lanc...

The malarial parasites are unicellular organisms whose cycle of development from beginning to end takes place within the reel blood corpuscles. They are, therefore, parasites (cytozoa) of the erythroc...
