You know the indols, the phenols, and the amins are produced both by putrefactive bacteria and by the process of metabolism, the burning up of the tissues in the process of utilizing the energy that means life. But under normal circumstances, the amins are not present in the blood in any such quantities as I have discovered by this new method of diffusion."
Heated with bromine water to 120°C. it decomposes into bromoform, carbon dioxide, nitrogen, and pyridine. Turning now to the non-volatile and oxygenized bases, we take up first the opium alkaloids. Morphine, C H NO , is a tertiary amine, and appears to contain a hydroxyl group like phenols, to which class of bodies it has some analogies, as is shown in its reaction with ferric chloride.
The oxygen is taken up by the iron to give oxide of iron, and benzene is obtained, thus: C H OH gives O and C H . But there is another hydrocarbon called naphthalene, C H , and this forms not one, but two phenols.
