EXPERIMENTS TO DEVELOP A MORE WIDELY USEFUL METHOD OF BLOOD-TRANSFUSION

In the present discussion a comprehensive review of all methods of transfusing human blood would lead us too far from our immediate subject. It will therefore be expedient to dismiss briefly and with very general consideration those methods of transfusion which involve the direct anastomosis of blood-vessels and not to attempt to estimate their relative merits. For a detailed discussion of the difficulties and limitations of this class of operation the reader is referred to the notable work of Crile published in 1909. Since the introduction of Crile's method, other ingenious devices have been contrived to facilitate the accomplishment of transfusion by an end-to-end junction of the blood-vessels, and there have been numerous accounts of the success of these operations. Less notice, however, has been given of the failures which from time to time have occurred. From a study of the literature, and from the personal
