1903.] Fats accompanying Absorption from the Intestine. 149 



The olein found in this experiment arises from the fat present in the pig's 

 pancreas (compare Experiment 7). The amount in No. 4 is less indeed than in 

 Nos. 1, 2, and 3, but tliis is most probably due to the protective action of the soap 

 present which is attacked by the active substance of the gland. 



JExpt. 7. Clear pancreatic extract (pig) m 0*75 per cent, saline, 1 of gland to 

 7 of saline ; period of extraction = 23 hours ; period of digestion = 16 hours : 



Expt. 8. Abdominal lymphatic cells (pig) in 0*75 per cent, saline, 1 of gland to 

 7 of saline ; period of digestion = 15 hours : 



Expt. 9. Clear extract of abdominal lymphatic gland cells (pig) in 0*75 per
