Plate for heating blood preparations. A, copper plate; C, blood preparations; F, iiipuil. end of 15 minutes a glass rod which has been dipped into water be passed over the plate, beginning at the end away from the flame, a })lace is reached where the water begins to ])oil; this region of the copper plate is looked upon as having a temperature of 100° C; it is represented by a dotted line in the diagram. The blood prei)arations (C) are placed on the plate (blood side up) Ijetween the flame and this imaginary line (nearer the latter), and heated for a time varying with the stain to be used. The l)lood of any vertel>rate may l>e spread and fixed as above directed. When desired to make preparations from fish, am[)hil)ian, or reptilian blood, the blood is most easily obtained from the heart. This, after exposure, is nipped with a pair of scissors, a small drop of the flowing blood is picked up on the end of a clean glass rod, quickly transferred to cover glass, and spread in the usual way, Bird's blood is readily obtained from one of the toes, which, after anassthetizing the animal, may be cut or partially amputated; a small drop is taken from the flowing blood, and spread. Preparations of red bone marrow, of the .spleen, or oilympli (jJ((nds may also be prepared after this method. Very small pieces of the tissue are })laced between two.
