(2) 75 ce. of the dust-shaped lipanine-ascites-emulsion are mixed with 25 ec. 
ox-blood, although not before a current of air has been led through the mix- 
ture (1) during 12'/. hours. After intermixing, the liquid is treated at the same 
time and in the same way as in (1). Only here, as has been mentioned, no air 
is allowed to pass through. Ether-extract 0.186 gr. 
(3) 75 cc. of the dust-shaped lipanine-ascites-emulsion produce an ether-extract 
of 0.219 er. 
(4) 75 ec. of dust-shaped lipanine-serum-emulsion are mixed with 25 cc. ox- 
blood. Current of air for 121, hours. Dried with sand, extracted with ether. 
Kther-extract 0.359 er. 
(5) The same as experiment (4), however without the current of air. Ether- 
extract 0.364 gr, 
(6) 75 cc. of the dust-shaped lipanine-serum-emulsion. Ether-extract 0.369 er. 
It appears from (1) and (2), that in passing air through the mixture 
of blood and dust-shaped lipanine-ascites-emulsion (artifical chyle), 
fat disappears. 
On comparing (2) with (3) it appears that also when a current 
of air is not passed through, a httle fat is analysed. As the 
experiments of COUNSTEIN and MricHaërrs have pointed out, and we 
have been able to confirm, this transformation takes place in conse- 
quence of the drying of the emulsion in presence of blood and air. 
It appears from (4) and (5), that the passage of air through the 
mixture of dust-shaped lipanine-serum-emulsion and blood, causes 
no transformation of fat, which is confirmed by the result of (6). 
Two repetitions of the experiment. 
Ox-blood was now again taken; duration of the passage of air 
28 and 18 hours. Room-temperature. 
(1) 75 ee. dust-shaped lipanine-ascites-emulsion + 25 cc. ox-blood. Passage 
of a current of air through the mixture for 18 hours. After that dried with sand 
and extracted with ether. Ether-extract in the two experiments 0.215 Gr. and 0.114 Gr. 
(2) 75 ee. of the dust-shaped lipanine-ascites-emulsion are mixed with 25 ce. 
ox-blood, after air has been conducted through the former mixture for 18 hours; 
after mixture the whole mass is treated instantaneously, consequently at the same 
time with (1), for the determination of fat. This experiment is therefore similar 
to (1); with the exception that no air is conducted through. Ether-extract 0.498 
and 0.288 Gr. 
(8) 75 ee. of the dust-shaped lipanine-ascites-emulsion give from 0.562 and 
0.315 Gr. 
(4) 75 ee. of the dust-shaped lipanine-serum-emulsion are mixed with 25 ce. 
oxen-blood. Passage of air for 18 hours. Drying with sand, extraction by means 
of ether, free of water. Ether-extract 0.401 and 0.512 Gr. 
(5) Same experiment (4), but without passage of air. Ether-extract 0.394 and 
0.321 Gr. 
(6) Passage of air through 75 ce. of the dust-shaped lipanine-ascites-emulsion. 
Ether-extract 0.567 Gr,
