Abstract
The foot pads of the cat were used as experimental material and electrical stimulation applied with standard methodology. In the absence of reabsorption, after 2, 4, or 6 minutes at 12 per minute stimulation frequency, no sweating occurred. On the assumption that the sweat formed per secretomotor impulse volley is constant, this would indicate that the secretory and reabsorptive actions of the glands come into balance when the secretory action is proceeding at some 1.65% of capacity, i.e., the secretory power of the sweat glands is about 60 times greater than their reabsorptive power. As the frequency of test stimulation is lowered from that which is maximally effective, the amount of sweat produced declines. By this fact rather than latency of sweating, the average glands come into secretory-reabsorptive balance at somewhat higher frequencies than do the most powerful glands.
