An ass had a pint of infusion of rhubarb given to it in the evening; the same dose was repeated at six o'clock the next morning, and again at nine o'clock, and at twelve. At two o'clock the animal was pithed, and two ounces of blood were taken from the splenic vein, two from the vein of the colon, and two from the inferior cava, in the lower part of the loins.

In the stomach and duodenum the rhubarb was found in large quantities; but none was met with in the coecum. The urine was impregnated with rhubarb, the orange tint upon the application of the alkali being very distinct. At the end of twenty hours, the serum of the blood and the urine corresponded exactly with that of the tincture in the former experiments, but was in a less degree of intensity. From these experiments it is evident, that the rhubarb passes from the circulation into the fluid contained in the cells of the spleen, and the urine; and in those made upon the dog, into the bile in the gall-bladder.
