The advantages of blood storage are stressed. Its greatest advantage is the saving of time, which may be a very important factor in an urgent case. A satisfactory method of blood preservation is described. While the preservation time of the oldest blood so far administered was thirty-five days, present indications are that this time may be considerably extended. It requires emphasis,'as previously stated, that the period during which preserved blood remains in a state suitable for transfusion is not a constant one, but varies with the method of preservation. With many of the methods in use this period is limited to about two weeks; but this time may be considerably extended by the method given here. The results in the first fifty cases transfused with preserved blood are compared with fresh blood transfusions. No essential differences were noted.
