Abstract

In a recent paper (Bazett, McGlone and Brocklehurst1), data were reported of the temperature changes that accompany temperature sensations, and it was pointed out that inferences as to the mode of stimulation were unwarranted until the end-organs were more surely identified and their depth established. In that work the skin of the forearm was employed; in the present work the prepuce has been selected, since histologic study of fresh tissue removed at circumcision is possible. The prepuce has the additional advantage that a fold of two layers of skin may be obtained, which is less than 2 mm. thick. Consequently, the rate of penetration of heat may be measured and yet the abnormalities introduced by buried thermocouples be avoided. It is proposed in this paper to present physiologic evidence with a brief account of anatomic data. A more detailed account of the anatomic structures demonstrable in the prepuce will
