    Such vibrations are almost exclusively given on nerves or veins and lymphatics. 1. Effect on the nerves. Stimulatory. These vibra- tions are therefore employed directly, a) To raise the nerve functionability, b) To induce a sensory effect, c) To induce a motor effect, d) To induce a secretory effect, e) To induce a vasomotor effect, and indirectly to produce a vast number of reflex effects. These results appear te be the same whether the vibration is towards the heart or away from it. 2. Effect on the veins. The venous return is has- tened, and the vein, if dilated, may be caused to contract. '3. Effect on the lymphatics. Centripetal running vibrations cause increase in the flow and in the absorp- tion by the lymphatics. Centrifugal ones have exactly the opposite effect, and therefore of immense value in the treatment of blood poisoning, i. e., when it is de- sired to prevent the absorption of the poisinous pro- ducts ; by gradually bringing the latter back to their starting point it is possible to remove them from the body by then expressing them through any opening in the skin, e. g.f an ulcer, wound, or other centre of in- fection. IV. Effects of running vibrations given with fine or medium strength. These have the same effect as the last group (though much less marked) and would be used over extremely painful areas. V. Effects of suction vibrations. The latter vibra- tions are used around abscesses and ulcers and similar conditions to prevent absorption of the products, and in the case of abscesses to enable them to come sooner to a head. After the abscess has opened, the manipu-
