The apparatus1 described here is offered for those who may possibly find it of some value, as we have, in the performance of transfusions and the administration of fluids in considerable quantity, by gravity, and in cases in which it is desirable to maintain the injection material at a more or less elevated and even temperature. The apparatus consists of a metal tank which surrounds the glass cylinder, except for a narrow slot at the front. Water at the required temperature is poured into the tank, and the temperature may be maintained or altered by draining the tank through the stopcock at the bottom and refilling. The slot at the front permits the mounting or dismounting of the cylinder and its contents at any time, even during the operation, with the tube and needle attached, and also provides for ready observation of the fluid within the cylinder at all times.
