In persons who practise masturbation there is sometimes a large quan- tity of indican found in the urine, and even the emissions of these persons, when dried on their linen, show spots which are bordered with a marked indigo blue or violet color. After ex- cesses in venery, as after sexual excitement in general, we find large quantities of indican in the urine. This is also a common occurrence in nervous and hysterical women. It is well known that in diseases of the central nervous system, especially in cerebro-spinal meningitis, very large quantities of indican are found in the urine (Oppolzer). Indican is usually present in the urine in solution, yet not infrequently indigo is also found in blue and bluish-black scales and flakes in the urinary sediment. In the nitric acid test for albumen the presence of a large amount of indican is shown by a narrow blue or bluish zone resting on the ring of brown coloring matter on the border between the col- orless nitric acid and the urine. If this bluish zone is distinctly seen, a beautiful separation of indigo may be obtained by the Jaffe test. Jaife's test is performed in the following man- ner : about ten cubic centimetres of urine and an equal quantity of strong hydrochloric acid are mixed together, and to the mixture are added one or two drops of a cold saturated
