In the following experiments the electrical skin resistance of a large number of new-born infants was measured and was found to be consistently much higher than that present in adults, except under unusual or pathologic conditions. The reasons for making these observations and the significance that they may have, not alone for the general understanding of skin resistance phenomena, but as well for the understanding of the physiology and neurology of the new-born infant, will be discussed.
For this purpose it is necessary to review briefly my previous observations made on the electrical skin resistance of adults with relation to various physiologic mental factors.
In these experiments, which were made chiefly on psychiatric patients, the resistance which is offered by the body to the passage of a very small constant galvanic current was measured. In keeping with earlier observations, it was found that practically all of the resistance offered to
