Thus, a dilute solution of toluidine blue i8 blue. Cell nudei and certain basophilic components of the cytoplasm are stained in this color. A number of other histological elements are stained red by toluidine blue. The laNer is the metachromatic color of the dye. Both extremes of color, as well as intermediate hues, may prevail in the same histological pre- paration.
