To obtain interme-diate values, colored riders are used, each representing and 5 per cent.,of hemoglobin when used with the disks from 70 to 120, but twice these valuesif used with the disks from 10 to 60. The blood is taken in a capillary pipet similar to that of von Fleischl,holding 5 cmm. of blood. The diluting chamber has a white backgroundof plaster of Paris and, when filled with distilled water in which one pipetfulof blood has been dissolved, yields a solution of i per cent. When filled thecell is covered with a blue glass cover. Method. The pipet is filled
