on the face or head was 1.25 per cent, of those bitten on 

 the hand; it was 0.75 of 1 per cent, of those bitten 

 on other parts of the body, a little over 0.25 of 1 per 

 cent. As a rule, only those persons are treated who 

 have been bitten on the face or hands or whose clothes 

 have been lacerated, so that the virus has passed into 

 the wounds. Ordinarily, a certificate from a physician 

 or a veterinarian that the animal was rabid is required 

 before vaccination; but if the animal cannot be found 

 or the wounds are severe vaccination is performed with- 

 out it. Taking only the cases in which rabies has been 

 confirmed in the animal by a veterinary surgeon, the 

 mortality of the cases treated at the Pasteur Institute 

 in Paris is only 0.6 per cent. a proof, it would seem, 

 of the trustworthiness of the statistics. In view of this 

 fact there can no longer be any doubt of the value of 

 Pasteur's antirabic treatment. It has been stated by 

 some that the percentage of persons killed by the bites 

 of rabid animals is inconsiderable; but according to the 

 reliable statistics of Leblanc, from 1878 to 1883, out 

 of 515 persons bitten in Paris 83 died of hydrophobia, 

 a mortality of 16 per cent.; most authorities place the 

 mortality at a much higher figure. Extensive bites 

 on the face and head are considered to be particularly 

 dangerous ; the mortality of these is said to be at least 

 80 per cent. The bites of wolves seem to be more fatal 

 than the bites of dogs or other animals; the mortality 

 of these, in spite of the most intensive treatment, is 

 stated to be still 10 per cent., as against a previous 

 mortality, without specific treatment, of 40 to 60 

 per cent. But even Pasteur's antirabic treatment 

 appears to be unavailable when symptoms of the dis- 

 ease have manifested themselves. Our results in the
