as small scales, -which melt at 53° 0. It is tolerably soluble in hot and less soluble in cold water ; readily soluble in alcohol, ether, chloroform, benzol, and petroleum ether. It forms a combination with picric acid, consisting of red needles, which are decomposed on heating with caustic soda, but pass over without decomposition when distilled with ammonia. Indol has a peculiar excrementitious odor. Skatol crystallizes in small plates, which melt at 95° 0. It is less soluble in water than in...dol, but in the presence of steam it distils readily. It is readily soluble in alcohol, ether, chloroform, and benzol. With picric acid it forms a crystalline compound, which does not decompose on being heated with caustic soda, but passes unchanged into the distil- late. It has an intense fetid odor.
