TABLE XVII. 



(c) — The Choleraic material introd^iced having become Putrid. 



The positive results recorded in the foregoing Table (No. XVII) are not so 

 numerous as were the results obtained in our previous experiments with putrid material, 

 or in those now recorded on perfectly fresh choleraic material. This, possibly, is owing 

 to the comparatively few experiments that have been undertaken on this occasion. Of 

 t he eight animals experimented upon, only one was materially affected, and it so happens 

 h at in that case the material introduced had been subjected to a temperature of 

 2l2°F. a few minutes previous to being injected. 



To sum up the results recorded in the tables of this section, showing the effect 

 of the injection of choleraic alvine discharges into the veins of animals (Tables XV — 

 XVII), it may be stated that of the thirty-six observations tabulated, fifteen yielded 

 positive results, or somewhat less than 42 per cent. In nineteen experiments the 

 material was not subjected to heat, and in seventeen cases the material had been 

 heated up to 212°; the mortality from the former proved to be 36'8 per cent., and
