The olein found in this experiment arises from the fat present in the pig's 
pancreas (compare Experiment 7) ; it is true that the amount in the control, No. 4, is 
somewhat less than that present in the other three, but this is probably due in great 
part to the protective action of the soap present in Nos. 1, 2, and 3, which is attacked
