they were only two in number, and, from more than one point of 
view, they are questionable. 
If we consider that, as yet, no hypothesis even has been formed 
as to the way in which the fat is resorbed in the large intestine, 
an investigation of this subject will not be deemed superfluous. 
In the first place we wish to know with certainty whether the 
Jarge intestine is indeed able to resorb fat. 
I. Does the large intestine possess the power of resorbing fat? 
A loop is taken out of the large intestine of a dog in a state of 
narcosis, is cleaned out inside, and by means of strings tied round it 
is divided into three equal parts a, b and c. An emulsion of lipanine 
(olive oil with 6.4°/, of oleic acid) in a solution Nag COs of 1/9°/, 
is then introduced into the middle part b; nothing is introduced 
into the exterior parts a and c. The intestine is then replaced, the 
central cavity closed, and four hours later the intestine is removed 
and by administering more chloroform the animal is killed. 
The mucosa of the central part bh, which contains no more fluid 
is prepared and cut into small pieces. As a means of control the 
mucosae of the two outer pieces are also cut into small pieces, 
placed in two small receptacles, and as much emulsion added as 
was injected into b at the beginning of the experiment. The fat in 
the three receptacles is then with the utmost precaution determined.

§ pCts. lipanine emulsion in Na, CO, of ‘/2%/9 is injected. Four hours later 
the intestine is eliminated. Isolation of the mucosae, cutting into pieces. To 
the mass a and e 12.5 ce of the emulsion is added. After it has been dried. 
the extract of ether yields the following results: 
Ether residu of intestine a (mucosa + emulsion) = 0.635 Gr.

Mean ... =0.649 Gr. 
Ether residu of intestine 4 (mucosa + not resorbed fat == 0.499 Gr. 
This proves that 0.649—0.499 = 0.150 Gr. of fat has been absorbed out 
of the intestine 4 during these four hours. 
Another experiment on another animal resulted in a resorption 
of @.482 or. of fat in four hours. 
These two experiments and many others of which we shall speak
