nied by a general reaction, proportioned to the intensity of the local action, 

 and complicated with gangrenous accidents which may cause the death of 

 others. 



Ill tlic experiment made by the Committee, inoculation has 

 proved benignant in its effects, in Gl out of a 100 of the inoc- 

 ulated subjects ; grave and complicated with gangrenous acci- 

 dents, in 38 ; mortal, in 11 ; 88 subjects out of a 100 have 

 consequently recovered their health after inoculation — 61 with-

 organism of the greatest number of animals on whom it is practiced 

 with an immunity which protects them against the contagion of the 

 disease for a period of time remaining to be determined, but which the 

 experiments detailed above do not show to be less than six months. 



The following table presents to the eye the calculated results 

 afforded by the two sets of experiments on inoculation and 

 cohabitation instituted by the Committee : — 



The first fact which strikes us in this table is, that inocula-

 designed to prevent. Besides we must take into consideration
