Although phenol is not an ingredient of human urine, as such, yet Stadeler extracted it from human urine, as also from the urine of the horse and the cow. Quite recently Baumann1 has established the presence of phenol-sulphuric acid in horses' urine, and he found the same compound in the urine of persons who had been treated medicinally with phenol. There seems also to exist, both in blood and urine, another compound, as yet unisolated, which may yield phenol. In the same manner cresol, C7H80, while it is not a normal ingredient of human urine, may be obtained as an educt therefrom under certain circumstances. The Colouring Matters of Urine. Under the name of urobiline Jafi has described2 a colouring matter which he first observed in the urine of fever patients. Although afterwards detected in all specimens of urine, it seems to be produced therefrom only by standing, and not as an original constituent. It has never been isolated nor analysed, but merely diagnosed spectroscopically, and named under the assumption of some connection possessed by it with a biliary colouring principle. The subject has attracted other workers, but the results obtained have only been productive of new incongruous names and considerable dissension. It will therefore be passed over without further comment. 1 Pfluger'a Archiv. 13 (1876) 2 and 7. Arch. Pathd. Antct. 47, 405. Omichyl-oxide was the name given by Scharlingl to a principle which he extracted from urine as follows: --The urine was concentrated by freezing and removal of the ice, and extraction of the concentrated solution with ether. By distillation of the ether extract, and washing of the residue with water, urea was removed, and the colouring matter remained behind. Scharl...
