The malarial fevers, haemoglobinuric fever and the blood protozoa of man . ry numerous quotidian aestivo-autumnal and pigmented forms were common, and upon one occasion twosegmenting forms were observed in the peripheral blood. The organismsappeared to be most numerous during the latter portion of the ring-forms were very minute, indistinct in outline, and actively pigmented forms were circular or oval in shape, and contained one or twonearly black pigment dots. The segmenting forms were intracorpuscular andin one instance the segments numbered six, in the other eight. Numerouscorpuscles showed double or triple infection. Treatment.—Quinine grm. every four hours. The temperature chart in this case shows an unusually high range of feverfor a quotidian aestivo-autumnal infection, but is not otherwise resembles, even more closely than that of Case I, an ordinary double tertianchart, and it would obviously be impossible to make a diagnosis of the type of 198 THE AESTIVO-AUTUMNAL MALARIAL THE AESTIVO-AUTUMNAL MALARIAL FEVERS. 199 infection in this case without the aid of the microscope, and this case well il-lustrates the importance of a microscopical examination of the blood in thediagnosis of malaria. The prompt subsidence of so pronounced an infectionunder large, repeated doses of quinine is worthy of attention. Case III. Chart 8.—C. T. The history in his case is briefly as follows:The patient had never been in the tropics and his malaria was contracted atFortress Monroe, Va. His illness began with a slight chill, nausea, vomiting,and severe headache and backache. He has slight epistaxis and complained ofsome abdominal tenderness. His temperature reached ° after the chill. Physical examination showed an enlarged spleen, general abdominaltenderness, hot, dry skin, flushed face, injected conjunctivae, and a pointed,tremulous tongue thickly coated with a white fur; the pulse was full, an
