ivity of the heart, but by raising thetemperature of the blood, and thereby stimulating the sweatcenters. The temperature may be raised by violent exerciseto 104° F. 6. Percussion and friction. 7. Certain drugs. 8. Stimulation of the secretory nerves by electricity orother means. Physiological experimentation has shown that there arespecial sweat centers and nerves. The sweat nerves of thehind leg of a cat lie in the sciatic nerve. Stimulation ofthis nerve has caused sweating in the sole of the foot, ofa cat forty-five minutes after death. Mustard held in oneside of the mouth will cause perspiration of the skin ofthe face of the same side. The centers of the sweat nervesfor the palms lie in that portion of the cord that gives originto the brachial plexus. Stimulation of the cervical sympa-thetic of one side causes sweating of the face and arm of thecorresponding side. The small blood-vessels are usually dilated in conjunctionwith sweating through excitement of the vasodilator nerves;

ANATOMY AND PHYSIOLOGY IN RELATION TO HYDROTHERAPY. 65 but sweating may occur with a pale skin,— the result of fear,pain, collapse, shock, or the death-agony. Stimulation of a motor nerve causes sweating of the skinover the muscles supplied by the nerve, and of the same areaof the opposite side of the body, and independently of anychange in the circulation. 9. Mental excitement, as in hysteria and neurasthenia,often giv^s rise to sweating, especially of the head, palms,and soles, and sometimes of only one side of the face. 10. Profuse perspiration occurs as a symptom in certaindiseases, as intermittent malarial fever, phthisis, and acuterheumatism. 11. The appearance of sensible perspiration is encouragedby a moist, warm atmosphere, in consequence of the lessenedrapidity of evaporation. Perspiration is decreased by — 102 1. Cold. 2.
