power of the large intestine is, under the given circumstances, not 
inferior to that of the small intestine. 
I say: “the resorptivepower,” by which I do not mean, of 
course, that in normal life the large intestine resorbs as much, per 
unit, of the surface of the mucous membrane, as the small intestine. 
Nor is that the case. For the fat is supplied to the small intestine 
in a pulpy, sometimes almost liquid mass, whereas the large intestine 
must absorb the fat from a more solid condition, which is, of 
course, done with less facility. Moreover, on reaching the large 
intestine, the contents have already rejected the greater part of 
the fat, and consequently what, in normal life, the large intestine 
absorbs in fat will amount to less than what the small intestine 
resorbs. 
What our experiments teach us is this: that when the lipanine- 
soap-emulsion is supplied to the unit of the surface of the mucous 
membrane, an almost equal quantity of fat is resorbed. 
sesides in detached pieces of the intestine, we have now also 
studied the resorption of fat in a fistula of the large intestine. In 
somewhat over a day we saw from a lipanine-soap-emulsion about 
10 gram of fat arrive at resorption in 12 hours. 
If we consider that this quantity is about the same that PLANTENGA 
in the course of twenty-four hours could bring in maximo to 
resorption in a human being whose large intestine possesses a much 
larger surface of mucous membrane than that of the dog, it then 
becomes highly probable that also in man, if we also employ 
lipanine-soap-emulsions we shall be able to bring about a much more 
considerable resorption of fat than we have hitherto obtained with 
other emulsions. 
The emulsion with soap solution yields another practical advan- 
tage, viz. that resorbed soap contributes as such to the absorption 
of fat, for, as we have seen, the soap is converted into fat. 
From a practical point of view it would be of importance system- 
atically to examine what will be the most favorable proportion of 
lipanine and soap-solution, and also what concentration must be 
given to the soap-solution in order to make the resorption as great 
as possible. We shall have further to discover how much the extent 
of the resorption depends on the volume of injected emulsion and, 
therefore also on the respective times of injection. 
We have, however, not pursued the subject further in this direction.
