To the various kinds of transfusion must now be added this form, originally proposed by Ponfick. With antiseptic precautions, a trocar with canula is passed through the abdominal walls in the linea alba. A flexible tube, with a glass funnel attached, is then connected with the canula—the trocar being withdrawn —and defibrinated blood is poured into the cavity. Excellent results follow this practice, which the researches of Bizzozero and Golgi have shown to be based on sound physiology. This method has been used successfully by Von Kaczorowski and others in the various maladies in which the other modes of transfusion have been employed. Some adverse reports have, however, been made. Peritonitis has been caused by the procedure, but in these cases the subjects operated on may have been unsuitable ones. On the whole, peritoneal transfusion, which at one time promised to be a valuable measure, must be regarded as still subjudice—if, indeed, its utility is not questionable.

Dr. Joseph W. Howe, of New York, who has made many valuable observations on transfusion, in a recent issue of the "New York Medical Journal" (February 3, 1883), announces that no other expedient can be properly substituted for the intra-venous injection of blood. When life is endangered by haemorrhage, Dr. Howe holds that it is not advisable to wait for intestinal or peritoneal absorption, but that intra-venous transfusion should be practiced without delay
