An international system of electro-therapeutics : for students, general practitioners, and specialists . ^The two lower axles, TFand PF^, each <MiYvy a large pulley, R and R^^and a toothed wheel; the large pulleys, R and i?i, are respectively unitedby means of straps to the superior pulleys, r and r^. The axle, TF,moreover, carries the handle, k. This whole arrangement allowsthe two cylinders to be turned in the reversed direction, when thehandle rotates only in one direction. The wooden frame carries,besides, two uprights, the lower parts of which are made of glass and theupper of metal; they terminate in the metallic knobs, m and n. In themiddle of these supports are two metallic knobs, Sk and ^f^^, each carryinga collecting comb in close proximity to the external cylinder; whilst onemetal double comb, sk sk^, inclosed in the small cylinder, is carried bythe fixed axle, e f. In the ballsm and n are the conductors, A^ and A^^. Fig. 5. which can be moved to and fro horizontally. The turning of the handle,k^ brings about the rotation of the outer cylinder, T, through the trans-mission of movement by means of the pulleys R and r ; whilst at the sametime, in consequence of the turning of the toothed wheel, the axle TFjrotates in an opposite direction, and this motion carries the small cylinder,Ti, over by means of the pulleys R^ and r?^^. If the knobs of the con-ductors are brought near each other so as to come into contact, when thehandle is turned in any direction it suffices to touch the surface of theexternal cylinder with a piece of hard caoutchouc, which has been slightlyrubbed on the clothes, either above or below the middle of the drum(corresponding with the middle of the inner vertical double comb). Thisexciting or charging of the machine is manifested by a whizzing the motion be stopped, the electric charge of the cylinders lasts forseveral hours. If the handle be turned in the opposite dir
