    hips, with partial paralysis of lower extremities. Has had this trouble for the last three years. Pains at times very severe. Takes morphine hypodermically to relieve suffering. Has severe oxalaemia and cystinasmia. - ^ Placed the fresh blood in a clean glass-stoppered bottle, and set aside at a te^iperature ranging from 6o° to 75° Fahrenheit. Had a healthy appearance, save that it was rich in fibrin, and contained granules of cystine and oxalate of lime, also spores of the Zymotosis regularis. A drop freshly drawn and placed between the slides of the microscope and allowed to stand for twenty-four I hours, afforded no cholesterine crystals. I October 12.—The bottle of blood was well shaken, I and a drop placed between the slides of the microscope. This was done at i p. m. At 4 p. m., three hours after, crystals of cholesterine had begun to appear all around inside the edges of the thin glass. The Z. regularis was rapidly developing into filaments. Blood in bottle, which, when first drawn, was of a beautiful, clear red color, now had a bluish purple tinge. Coloring matter of the discs partially escaped and dis- solved in the serum. The fact that no cholesterine crystallizes in the freshly drawn healthy blood, while it does crystallize under similar circumstances, in the same blood, after 1 it has stood for two or three days in clean, tightly ,|p corked glass-stoppered bottles, and the coloring matter of the discs partially escaped and dissolved in the serum, is interesting, and demonstrates the fact that the choles- terine is held by the blood disc in the freshly drawn
