And do not other equally important changes take place? This € admit ofa very perfect investigation. * The constant agitation whichis maintained in the intestines, preserves the chyle in a state of perfect admixture with the other fluids, until absorption has taken place. By standing at rest, the separation, mentioned above, is evident and perfect. i But I am disposed to think, with Professor Dover son, and others, that the use 6f the mucus is to lu- bricate the internal coat of theimtestings, and, per- haps, to dilute their contents. It has been suggested that digestion can be per- at in the duodenum and lower bowels, when the _ food has eer ‘submitted to the action of the sto- npn its fluids. ~ dn two experiments by Macen- 5 e failed, and the other was attended with par- tial success. Too much reliance ought not to be _ placed on experiments, that require such severe and cruel vivisections, as were resorted to in these cases. It is possible, as-suggested by Dunexison, that the Soreseatl of crude aliment in the duodenum, may ex- cite the discharge of gastric Juice im the stomach, its expulsion into the duodenum, and its consequent ac- tion on the food, before it is affected by the bile and pancreatic juice.
