Summary. I. The specific reaction rate for the change of cinchonine to cinchotoxine by the catalytic action of acetic acid in large excess has been determined for two concentrations of acetic acid. 2. The reaction has been found to be monomolecular with respect to the alkaloid, and the catalysis has been found to be monomolecular with respect to undissociated acetic acid.
