The formation ofcarbazol from thiodiphenylamine by the action of copper fur-nishes some proof in support of the formula given above; but asthis is the only reaction clearly tending to show that carbazol is adi-ortho derivative of diphenyl, and therefore that it contains thepyrrol ring, further evidence in the same direction appearsdesirable. In making the experiments which led up to the facts here*recorded, I hoped to find points of resemblance between carbazoland pyrrol for which the ^NH group alone, independent of thepyrrol ring, would not account, and thus to confirm indirectly theabove formula of carbazol. Runge, the discoverer of pyrrol, observ
