of the villi in its motion, causes the little fatglobules, already in a 
state of thorough division, to pass into the shape of dust. Surely this 
lymph-current works slowly, but it should be considered, that the 
time at its disposal is not short; 30 hours after a rich meal has 
been taken the chyle still carries away fat. 
As is. well known COHNSTEIN and Mricnaëris have pointed out 
in two interesting publications !), that, when blood has been mixed 
with chyle-fat and air is then carried through the mixture, the fat 
disappears, and a combination dissoluble in water takes its place. We 
were interested to know, when blood is mixed with our artificial chyle 
(dust-shaped emulsion of lipanine in ascites-liquid) and a current of 
air was made to pass through, whether a disappearance of fat would 
likewise be observed, 
To this purpose 240 ce. of the ascites-liquid with 15 cc. lipanine 
were shaken for 1%, hour. After centrifugalizing, the undermost of 
the two layers is removed, which contains the fat exclusively in 
dust-form. 
Of the artificial chyle attained in this manner: 
(1) 75 ee. was mixed with 25 ee. horse-blood rich in erythroeytes *). For 
23 hours a current of air is allowed to pass through under a temperature 
of '=,)6° 0. 
(2) 75 ce. of the artifical chyle are mixed with 25 cc. blood. No current of 
air is allowed to pass through. 
The liquids (2) are mixed just before drying takes place. 
At tne same time exactly the same experiments are performed 
with dust-shaped lipanine-serwm-emulsion, consequently : 
(3) 75 ee. of a dust-shaped lipanine-serum-emulsion are mixed with 25 ec. 
horse-blood, and through this mixture air is allowed to pass through for 23 
hours (the same current of air as under (1). 
(4) 75 ee. of the dust-shaped lipanine-serum-emulsion are mixed with 25 cc. 
of blood. No current of air passes through. 
The liquids (4) are mixed just before drying takes place. 
(1), (2), (8) and (4) are placed into two small receptacles, mixed with 20 gr. 
of pure sand and being stirred, dried in a temperature of 80°. After having been 
pulveriged, extraction with ether, free of water, in a Soxhlet apparatus for 48 
hours.

*) Such blood is obtained by leaving defibrinated horse-blood to itself and by 
pipetting off the serum after the red blood-corpuscles have settled down.
