quotidianaestivo-autumnal fever is characterized by a febrile paroxysm occurring everytwenty-four hours, corresponding to the sporulation of Plasmodium falciparumquotidianum. Otherwise it varies but slightly in its symptomatology fromthe tertian type. As in the latter form, the three stages described may generallybe observed, but in the quotidian type the chilly sensations are more severeand there is often a distinct chill. Sweating is also more pronounced, but isnot so marked as in the simple tertian and quartan fevers. The temperaturecurve is entirely different. It consists in the abrupt rise of the temperature to103° F. or more, succeeded by as abrupt a fall. The attack lasts, as a rule, onlyabout eight or ten hours. The temperature curve seldom remains regularfor long at a time, for the attacks tend to run into one another, thus giving riseto more or less continuous fever. This is especially true of the perniciousattacks. (Chart 5.) THE SYMPTOMATOLOGY OF THE MALARIAL FEVERS, 183

(^ 184 THE SYMPTOMATOLOGY OF THE MALARIAL FEVERS. To one who has studied aestivo-autumnal malarial infections in regionswhere they are endemic and who has been so fortuate as to observe suchinfections uninfluenced by treatment or other complicating factors, the greatdifference in the temperature curves of the tertian and quotidian type is alonesufficient to distinguish them, and when we add to this difference the variationin the morphology and developmental history of the two plasmodia concerned,we must admit that aestivo-autumnal malaria is caused by two species of plas-modia, as first described by Marchiafava and Bignami. Analysis of the Symptoms of Malarial Infections.—It will be ofinterest and value to consider more in detail the symptoms observed in thevarious types of malarial infection. The Temperature Curves—I have already spoken of the temperaturecurves exhibited by malarial infections, and, while in uncomplicated cases adiagnosis of the type of infection might be arrived
