treated, in 1886, was 2,671 : of whom 25 died 

 = 0*94 per cent. 



It is to be noted, that the full advantage of the 

 treatment is gained not immediately, on the last 

 day of the treatment, but a fortnight later. That 

 is to say, if the last dose of protective cord were 

 given on the last day of a month, the patient would 

 not attain the highest degree of immunity until the 

 middle of the next month. This belief is supported 

 not only by experiments on animals, but by 

 observations on man. Therefore, at the Pasteur 

 Institutes, if the disease flares up within 15 days 

 after the last day of treatment, the case is reckoned 

 as one of those cases where the treatment was 

 begun too late : and is not included in the general 

 table of results, but is mentioned separately. The 

 number of these incompleted cases is not enough 

 to touch the fact that Pasteur's method brought 

 down the death-rate, in 1886, to 1 per cent., and 

 has kept it, from then to now, at 1 per cent., or less 

 than 1 per cent. Bernstein, with great industry, 

 has compiled the results obtained by 40 Anti- 

 rabic Institutes over a period of 18 years. The total 

 number of persons treated was 1 04,347. Of these, 

 560 died, 14 or more days after treatment =0*5 4 per 

 cent. If we add the cases which died during the 

 first fortnight after treatment, the mortality, still, 

 is only 0*73 per cent. (Remlinger, Bibliotheque de
