1. Introduction. It has been shown lately' that a hydroxyl group in the triarylcarbinols, particularly in the p-position to the central carbon atom, increases greatly the tendency of the compound towards tautomerization. Triphenylcarbinol is known only in one, the colorless, state; its p-hydroxy derivative, however, has been obtained2 in two distinct forms, the colorless and the colored, separable from each other and either readily changeable into the other merely by choice of suitable solvent. The distinctive behavior of these two carbinols is best explained, as has been shown, by assigning to them the two constitutions, respectively
