As said, the triple-stain is the only one really necessary for thepractitioner, and familiarity with one stain and the ready recogni-tion of the bodies differentiated by it is far more useful than doubtfulversatility or questionable proficiency. Malarial Organisms. These parasites are readily recognized inwet specimens by careful focusing, or th4y may be stained for per-manent preparations.

EXAMINATION OP THE BLOOD 249 of the class which grows in the blood and is therefore called h£ema-tozoon. This particular species is named in honor of its discoverer,Plasmodium malarice of Lavaran. The most- common form of thePlasmodium is found enclosed in the red blood corpuscle. It is a pale,segmented, mulberry-like body, surrounding a mass of pigment. Ifa little solution of gentian violet or fuehsin be added to the wetpreparation, the stain will impart itself to each of the fifteen ortwenty separate segments, differentiating a Seep-tinted, central nu-cleolus from the surrounding protoplasm of lighter stain. Some ofthese same bodies may be found apparently free from the corpusclewhich encapsulated them. The free bodies may be entire or in variousstages of disinteg
