The initial object of this research was the elaboration of an exact polariscopic method for the analytical determination of malic acid. The results, however, turned out to have a wider interest. A number of years ago, Walden called attention to the fact that uranyl salts enhance in a remarkable degree the optical rotation of optically active organic compounds of certain classes, particularly of polybasic oxyacids of the aliphatic series. This enhancement does not extend to carbohydrates in a degree sufficient to interfere appreciably, according to observations of Grossmann and others. Yoder has laid the foundation of an analytical method based on the facts alluded to.
