The local anesthetic action of a series of aryl-urethane compounds has been tested. All compounds appeared to possess anesthetic activity greater than that of cocaine hydrochloride, this difference being most marked in the case of the compounds with the longer substituted alkyl groups. A correlation was shown to exist between the duration of effect and the length of the substituted alkyl group in each of the two series.
