    were examined. The red corpuscles showed nothing abnormal in size or shape; no poikilocytosis. The leucocytes appeared to be about normal in number. The differential count of 1000 leucocytes showed: Lymphocytes 11.3 per cent. Large mononuclear leucocytes 11. Transitional forms 3 Multinuclear neutrophils 73.2 Eosinophils 4.2 December 19th, ninth day of the disease.—Red corpuscles, 4,092,- 000 ; colorless corpuscles, 5,500. December 26th, sixteenth day of the disease.—Red corpuscles, 2,226,000; colorless corpuscles, 6,800. January 6th, twenty-seventh day.—Red corpuscles, 1,426,000; colorless corpuscles, 8,000; haemoglobin, 24 per cent. Dried and stained specimens showed a marked pallor of the red corpuscles and considerable difference in size, though there was no great poikilocy- tosis. A few nucleated red corpuscles (normoblasts) were found. While making a differential count of 1000 leucocytes two normo- blasts were seen. The differential count of 1000 leucocytes showed : Lymphocytes 18.1 per cent. Large mononuclear leucocytes 22.4 Transitional forms 4.5 Multinuclear neutrophiles 53.1 Eosinophils 1.9 A large number of mononuclear leucocytes with almost transpa- rent protoplasm were noticed here as in the specimens of blood in Case I. Specimens stained with eosin and methylene blue showed considerable numbers of red corpuscles taking a diffuse stain, degen- erate forms (Ehrlich), polychromatophilic corpuscles (Gabrit- chewsky(4D>). January 14th, thirty-fifth day.—Red corpuscles, 1,352,666; color- less corpuscles, 6,500; haemoglobin, 27.5 per cent. January 24th, forty-fifth day.—Red corpuscles, 1,648,666; color- less corpuscles, 7,000; haemoglobin, 28 per cent. Stained specimens showed, as in the last specimen, a considerable difference in the size of individual red corpuscles; no great poikilocytosis. Numerous
