From experiments it is clear that nervous influences alone, in the absence ol any vascular changes, or in the total depriva- tion of blood, suflBce to induce the secretion of perspiration. If the central stump of the divided sciatic be stimulated, sweating of the other limbs follows, showing that perspiration may be a reflex act It is found that stimulation of the peripheral end of the divided cervical sympathetic leads to sweating on the cor- responding side of the face. Sweating during dyspnoea and from fear, when cutane- ous surfaces are pale, as well as in the dying animal, shows also the independent influence over the sudorific glands of the nerv- ous system. Heat induces sweating hj acting both reflexly and directly on the sweat-centers we may suppose. Unilateral sweating is known as a pathological as well as experimental phenomenon. Perspiration may be either increased or dimin- ished in paralysed limbs, according to circumstances. It is possible that there is a paralytic secretion of sweat as of saliva. The subject is very intricate, and wUl be referred to again qa account of the light it throws on metabdio proc
