Abstract
IN a previous communication1 mention was made of a device for rapidly and accurately reading the relative length of the packed red-cell column in the ungraduated capillary tubes used in the Guest and Siler2 microhematocrit technic. The purpose of this communication is to describe this device in greater detail.The usual methods for measuring hematocrit levels in ungraduated capillary tubes consist either of laying the tube on a ruler and converting the measured lengths of the plasma and packed cell columns to hematocrit percentage by simple computation or of placing the tube against a specially prepared scale of divergent lines. . . .
