In accordance with all these researches we may conclude, that 
by far the majority (on the average nearly 99°/,) of the thousands 
of miiliards of microscopically countable bacteria, excreted in 24 hours 
with the faeces, by a healthy, full-grown individual, are no more able 
to multiply; hence, these bacteria must be either dead, or at least 
so much attenuated that they can no more perform this important 
vital function. 
Between these two alternatives it is not difficult to make a 
choice. We see namely (Tables V, VI and VII), that the total 
number of bacteria in the faeces, kept at body-temperature, decreases 
regularly with great rapidity, which can only be explained by the 
decomposing and vanishing of dead organisms; in fact, in these 
faeces, too, the number of bacteria showing post-mortal alterations 
is seen steadily to increase. Ì) 
There is no risk in venturing to assume, that the same circum- 
stances, which in most faeces out of the human body cause the 
number of living bacteria to decrease, respectively prevent their 
multiplication, that these same circumstances also have their part in 
the death of that enormous nuinber in the faeces, whilst these are 
still enclosed in the intestinal canal; future researches will have 
to throw more light on this point. 
The results of the foregoing researches are in brief as follows: 
1st By a healthy, full-grown individual are excreted in 24 hours 
with the faeces a much greater number of bacteria than was hitherto 
known (on the average 8800 milliards, occupying 0,31 pCt. of the 
solid substance of the faeces) 
ond By far the greater majority of these bacteria have died (on 
the average nearly 99 pCt.), only a small percentage are living (on 
the average above 1 pCt.). 
3rd In most faeces anti-bacterial actions may be observed, which, 
out of the human body, at 37° C., often diminish the number of 
living germs, or at least prevent their (vigorous) increase.
