The study of the anæmia in chicks produced byP. gallinaceum shows the following characteristics. They are: (1) a slightly lowered colour index, (2) Hyperplasia of the bone marrow corresponding with a drop in the red cell count, (3) and slightly raised mean red cell area.
Small late erythroblasts which are spherical occur in the peripheral blood when the maximum strain is placed on the hæmopoietic tissues and the normal elliptical erythrocytes are found in the peripheral blood as the bird recovers from the acute infection.
It is interesting to note that the rapid reduction in the number of parasites following the peak of the parasitæmia may be related to the character of the parasites apparently preferring the erythrocytes to the erythroblasts.
