The purpose of this investigation has been to determine the sense receptors of pressure and vibration by means of cutaneous excision. The receptors involved in the mediation of pressure sensitivity have long been subject to speculation. The nature of the processes underlying the perception of vibration has been the subject of controversy for the last four decades. Vibration sense has been variously considered as mediated by the bones and periosteum and as a function of the tactual end organs responsible for "contact" and "pressure" sensibility, and some writers have even included a special "vibratory sense" as the sensory mechanism responsible for the perception of this modality. A summary of the work on vibratory sensibility is largely history of this controversy and has been presented in a recent review by Geldard.1 Of the several views as to the nature of vibratory sensitivity growing out of the studies of physiologists, psychologists
