to be rendered an emulsion of, required to be submitted to the 
action of upwards of three pints of pancreatic fluid. 
2. The secretion, instead of being continuous and regular, 
manifests irregularities which give it an intermittent type. If 
at one moment it is very abundant, at another it lessens and 
soon becomes inconsiderable, or ceases altogether to resume a 
progressive augmentation of action, which, after having lasted 
for a certain while, is anew succeeded by falling off. 
3. The most energetic periods of secretion correspond with 
the termination of rumination and the moment succeeding it. 
They are likewise in unison with the feeding hours of the animal. 
4. The secreted fluid exhibits complete emulsive properties 
only at its incipient secretions. Then it is thick and viscous, 
and contains a large proportion of the albuminoid principle, and 
with one part of olive oil to three parts of it (the pancreatic fluid) 
forms a perfect emulsion, unchangeably homogeneous. 
5. The fluid obtained an hour-and-a-half only after the estab- 
lishment of the pancreatic fistula is less albuminous, and incapable 
of being formed into an homogeneous emulsion, although the 
proportion of it in the mixture be augmented to double or triple 
what it was in the former mixture. After this, these properties 
grow weaker according as the secretion becomes more aqueous, 
though it never loses them altogether at any period of the ex- 
perimentation. 
6. As a consequence of its contact with oil, the pancreatic 
fluid, which is always alkaline, turns to acid along with the rest 
of the mixture. This property it preserves at every stage of 
the experimentation, and equally so at the ordinary temperature 
as at that of the body of the animal; the only variation being 
that the acidity of the emulsion becomes developed quicker and 
more surely in proportion as the fluid itself is more albuminous 
and its temperature is higher. 
M. Colin’s paper, of which the preceding contains the sub- 
stance, has been put into the hands of a committee, composed of 
MM. Magendie, Flourens, and Boussingault.
