1. For uric acid in excess; Boil the upper strata of urine in a test-tube and add a few drops of 4 per cent. acetic acid; at the end of 3 or 4 hours the uric acid will crystallize out just below the surface of the urine. 2. For indicanuria: Shake together 10 c.c. urine, 10 c.c. hydrochloric acid, and 5 drops 0.5 per cent. solution potassium permanganate; then add 5 c.c. chloroform and shake; the presence of indican will be indicated by a purple coloration followed by a deposit of blue pigment.
