Her...e it is seen that the smallest quantit}^ of blood to give a positive result was 5 drops, or 0.3375 c. c, and that this result was obtained only once out of three trials. Assuming 6,000,000 red cells and 10,000 leucocytes per cubic millimeter, we find as a possible proportion one trypanosome for 2,022,000,000 red cells and 3,370,000 whites. Hence to find the trypanosome in the circulating blood would be merely a piece of good fortune. Further, culture 444, containing 9 c. c. of blood, was negative, yet this amount of blood contains 90,000,000 leucocytes.
