the blood are the ones which form the pus corpuscles, by a pure 
and simple transformation of the former into the latter. But in 
sciences of observation , so-called, the illusion is so easy, that one 
remains satisfied with the observation. 
There remains one point which deserves the attention of the 
surgeon: this is the effects of our microbe, generator of pus, 
when associated with the septic vibrio. Nothing easier than to 
suppose, so to say, two distinct diseases and to produce what 
might be called a septiccemic purulent infection or a purulent 
septicoemia. While the microbe generator of pus forms, when 
alone, a white, thick pus, slightly yellow or blueish, odorless, 
diffused or surrounded with what is called a pyogenic membrane , 
and without danger if specially localized under the cellular tissue, 
ready, we might say, to be promptly resorbed; the smallest abscess, 
on the contrary, that is produced by this microbe associated with 
the septic vibrio, assumes a gangrenous, putrid and greenish 
aspect, and seems infiltrated in the softened tissues. In this case 
the microbe generator of the pus, mixed up with the septic 
vibrio, penetrates with it in all the tissues; even the muscles 
become inflamed, full of serosity, showing sometimes pus cor¬ 
puscles here and there, and seemed to be filled with two different 
organisms. 
By an analogous method the effects of the carbuncular 
bacteridie and of the microbe can be combined, and thus two 
different maladies be superposed, viz: a purulent anthrax or a 
carbuncular purulent infection. However, one must not ex¬ 
aggerate the predominancy of the actions of the new microbe 
over that of the bacteridie; if the microbe is mixed to the 
bacteridie in sufficient proportion, it may destroy it entirely— 
that is, prevents its multiplication in the body. Anthrax then 
does not appear, and the trouble, remaining all local, is only an 
abscess of easy cure. The microbe generator of pus and the 
septic vibrio being both anaerobic, we understand how one—the 
septic—would be interfered by the other. Nutritive elements, 
solid or liquid, are always plenty in the organism for so small 
beings; but the carbuncular bacteridie is exclusively aerobic, and 
the proportion of oxygen in every point of the body is limited
