    pighian tuft and capsule seemed to be filled with colored mate- rial, which could be traced along the tube, gradually becoming lighter in its progress downwards. In some of these animals the urine in the ureters, above the ligatures, was of a slightly blue color. No. 8. On the same day I injected a solution of the ferro- cyanide of potassium into the stomach and duodenum of a large cat, and then placed a ligature above the opening which had been made into the intestine in order to inject the solution. About ten inches below this point I made another opening into the intestine, and injected downwards into the jejunum and ileum a weak solution of sulphate of iron. A ligature was placed just below this opening, so that the contents of the intestine could not escape. The two solutions were thus separated from each other by ten inches of intestine which contained none of the solution. Ligatures had previously been placed on the ureters. This experiment was performed at 3 p.m. on Saturday, and the animal was found dead on Monday morning, so that it is not known how long she lived after the operation. The Malpighian bodies and uriniferous tubes were of a dark blue color, showing that Prussian blue had been formed in the course of the circulation, and had passed through the Mal- pighian bodies and uriniferous tubes. The urine was of a slightly blue color. No. 9. I may also state that I have injected a mixture of Prussian blue and water into the stomach and intestines of a cat, and have found the Malpighian bodies and tubes of a dark blue color; but I regret to say that I have lost the notes of the experiment, although the specimen of the kidney is still in my possession. No. 10. December 24, at 4 p.m., I tied the ureters of a small dog and injected a solution of madder into the stomach and intestines. This dog was found dead on the 26th. The Malpighian bodies were of a brilliant red color, exhibiting a most beautiful appearance. The tubes were dark red and some of them very darkly colored. Thin sections of the kidney were placed under the microscope, and then touched with a drop of solution of caustic soda or ammonia, when the Mai-
