From many other studies besides his own, the author concludes that kala-azar is characterized by a diminution of hemoglobin concentration, which in the majority of instances is 30 to 50 per cent. Other important symptoms are a reduction in number of red cells to 2,000,000 to 3,000,000, with a Price-Jones curve of 6.70 to 8.40 microns and a leukopenia of 2,000 to 5,000 cells. Erythroblasts average from 20 to 40 per cent and myelocytes from 11 to 20 per cent. While the thrombocytes are approximately 100,000, the hemorrhagic disturbances so often seen are usually accompanied with granulocytopenia.
There is an extensive bibliography, and, although written in Portuguese, the book is easily understandable to those interested in this subject.
