A fuller account of the technique employed and a more exact 

 description of the cutaneous lesions observed, of the possible value 

 of red blood cell mixtures, i. e., of suspensions of the mixed red 

 blood cells of several individuals, of the possible value of some 

 animal red blood cells for injection purposes, of the significance 

 of the persistence or disappearance of the reaction after an opera- 

 tion, and many other aspects of the subject will be discussed in a 

 future communication. The number of injections thus far given 

 is far too small to allow of positive conclusions as to the reliability 

 of this method for diagnostic purposes. The results obtained thus 

 far have been striking. The purpose of this preliminary report is 

 to call attention to the fact that it is possible to cause a local 

 hemolysis in the living body by the subcutaneous injection of 

 washed normal human red blood cells, and that in patients with 

 malignant disease, especially carcinoma, a characteristic and easily 

 recognizable local skin lesion is caused by this injection.
