These substancesare (1) albumin; (2) blood; (3) grape-sugar; (4) pus and tube-casts; (5) bile. (1) Albumin is present in various conditions mentionedunder Albuminuria, and may be recognized by the followingtests: (a) Boiling, after the addition of a few drops of acid, producesa copious white cloud of coagulated albumin. (b) Hellers test.—Place some strong nitric acid in the bot-tom of a test-tube, and carefully pour in urine above it. If theurine contains albumin, a dense white line forms where the twofluids meet. (c) Picric acid.—^Drop some strong solution of picric acid intoa test-tube containing urine. If albumin is present each dropcarries down a white cloud of coagulated albumin.

A similar result isgiven, however, by the urine of patients who have been takingiodide of potassium, so that for absolute certainty a drop of theurine must be examined under the microscope to find if blood-cells are actually present.
