Results. According to reliable statistics, the mortality of rabies 

 without the Pasteur treatment is about 16 per cent.; with the treat- 

 ment the average mortality is about 0.46 per cent. The mortality of 

 those bitten about the face or head is about 1.25 per cent.; of those 

 bitten on the hand, 0.75 per cent. ; of those bitten on other parts of the 

 body, a little over 0.25 to 1 per cent. In the Pasteur Institute of Paris 

 only such persons are treated as have been lacerated, so that the virus 

 has gained entry into the wounds. Viala 1 reports that during the year 

 1915 as many as 654 persons were treated, with a single death. Taking 

 into consideration only those cases in which the diagnosis of rabies 

 has been confirmed in the animal by a competent examiner, the mortality 

 of the cases treated at the Pasteur Institute in Paris for the past ten 

 years, and covering the treatment of nearly 6000 persons, is only 0.6 per 

 cent., which, compared to the average mortality of 16 per cent, without 

 vaccine treatment, speaks most favorably for the value of Pasteur's 

 antirabic immunization.
