422 THE QUESTION OF IMMUNITY AND ANTITOXINS 



by dry heat. When the patient bitten by the rabid animal is 

 prepared, 3 c.c. of this broth emulsion of spinal cord are inoculated by 

 means of a hypodermic needle (under aseptic precautions) into the 

 flanks or abdominal wall. On the following day the patient returns 

 for an inoculation of a cord of the thirteenth day, and so on until a 

 rabid cord emulsion of the first three days has been inoculated. As a 

 matter of practice, the dosage depends upon the three recognised 

 classes of bites, viz. (1) bites through clothing (least severe); (2) 

 bites on the bare skin of the hand ; (3) bites upon the face or head, 

 most severe owing to the vascularity of these parts. An example of 

 each, which the writer was permitted to take in the Pasteur Institute, 

 may be here added to illustrate the usual practice.
