This paroxysm wassucceeded by three others, all accompanied by chilly feelings, severe headacheand backache, nausea, and great nervous prostration. Physical Examination.—Patient somewhat emaciated; skin yellowish;mucous membranes pale; cheeks flushed; eyes bright; tongue broad andcoated; heart and lungs normal; abdomen rather tender; spleen slightly enlarged;bowels constipated; marked mental depression and general debility. Examination or the Blood.—The blood was examined at frequentintervals and numerous ring-forms, pigmented rings, and larger pigmentedforms of the tertian aestivo-autumnal plasmodium were found. No segmentingforms were observed. The ring-forms were larger than those of the quotidian 2o6 THE AESTIVO-AUTUMNAL MALARIAL h THE AESTIVO-AUTUMNAL MALARIAL lEVEES. 2C7 aestivo-autumnal plasmodium, being about one-fourth the size of the infectedred cell, irregular in shape, most of them presenting an enlargement at someportion of the periphery, thus causing the so-called signet-ring were refractive and sharply outlined, with clear protoplasm, and havinga sluggish amoeboid motion. The ring-form was sometimes lost during themovement of the organism, a clear, circular, hyaline disk resulting. The infectedred corpuscles, while more greenish in color than the uninfected cells, was notnearly as much altered in appearance as in the quotidian infections, and wasseldom crenated. The pigmented rings and larger pigmented bodies were present in smallnumbers. The rings showed a few fine pigment granules, generally inthe dilated portion of the ring, and these granules were often in rather rapidmotion. These pigmented rings still sh
