Result of Experiments withCastor-Oil.—It stimulates the in-testinal glands, but not the liver. It lowers the bile-secretion, probablyindirectly, owing to its action on the intestinal glands. The appearance of theintestinal mucous membrane was in complete harmony with the belief thatcastor-oil is an exceedingly bland purgative. VOL. XXIX.
