Thiscurve is simulated only by simple tertian fever with subintrantattacks, which is uncommon. Unfortunately this typicsequence is far from constant; the modifications are verynumerous and are too irregular to analyze. The symptoms of the hot stage are more pronounced than inthe infections previously described. The headache and back-ache are worse, the general depression is more profound, stuporand delirium may appear, and pernicious symptoms may the short interval the patient does not regain his ease. 57.—Quotidian estivo-autumnal malar as in the simple intermittent fevers, but the aching and pros-tration continue, and he may be unaware that the fever hasleft. Quotidian.—The quotidian estivo-autumnal fever is moreregular in its course than the tertian, especially at first, thoughthere is nothing characteristic in the temperature curve, whichmay closely resemble a double tertian or a triple it is apt to lose some of its regularity by anticipationor by lengthening of the paroxysms, whose average durationis from six to ten hours. The chill is rather more constant CLINICAL HISTORY I93 than in the tertian, otherwise the symptoms are identical, thepatient not regaining strength from one paroxysm to the interval the temperature is prone to sink, even as lowas to 95° F. Mixed Infections.—Infections with two or more species ofthe malarial parasite are known as mixed or combined infec-tions. The most frequent combination is of s
