previous report, in which perfectly fresh solutions of alvine discharges had been prepared. 

 Of these eight, one died ; but of the four previously recorded, not one. Consequently, 

 the mortality from the introduction of such a material (excluding of course such accidents 

 as embolism, etc.) may be referred to as averaging about 8 per cent. The mortality 

 resulting from the introduction of putrid material is, however, as we have previously 

 shown, considerably higher ; for out of seventeen animals thus treated, six died apparently 

 from the toxic influence of the solution introduced : thus yielding a mortality of 

 something like 35 per cent. — the period most fatal being when the material was from 

 three to four days old.

Showing, however, the fallacy of being entirely guided by averages in matters 

 of this nature, and apparently exemplifying the idiosyncrasies of animals in their 

 susceptibility to septic influences, are the facts that the mortality resulting from the 

 introduction of boiled solutions of fresh alvine discharges was greater than was yielded 

 when the same material was unboiled, and that the same fluid in some cases produced 

 a result, but in others did not. This appears to be the interpretation of the results 

 shown in the table given on the next page : — 



* With reference to the high temperature frequently recorded in apparently healthy dogs, it should be borne 

 in mind that this is probably owing to the high temperature of the fermenting fiscal matter in the rectum — the 

 rectum should therefore, when possible, not be selected for the application of the thermometer. 



t The result of subsequent microscopical examinations of the organs and tissues of this and of other animals 

 arc referred to under separate headings.
