Acetone may be recognized in urine bydirect testing, but it is, as a rule, better to look for it inthe distillate. A number of tests have been devised forits recognition ; the best of these are the four following :The iodoform test (Liebens) depends on the fact thatacetone readily unites with iodine in an alkaline solution,giving rise to iodoform. Alcohol reacts in the sameway, but only after some time, or when the mixture isgently warmed. To perform the test, a little urine in atest-tube is made strongly alkaline with caustic potash, anda solution of iodine in iodide of potassium is dropped intill the iodine color just disappears on shaking. If ace-tone be present the urine will assume at once a paleyellow turbidity, and gradually deposit iodoform in fine. SCMTZEfi
