This extractive is soluble in alcohol, butnot in ether ; it seems to have a great tendency to absorb fouradditional equivalents of oxygen (C3SH27N032 = oxurianine),but without suffering any change in its physical is probably a glucoside, for by the action of acids ityields a brown powder, insoluble in water (uromelanine), audthe filtered liquid reduces the cupro-potassic test like grapesugar. Urian and urianine are both decomposed when heated forsome time in the water-bath, giving products which are in-soluble in water. Watery solutions of both become severalshades darker when
