An international system of electro-therapeutics : for students, general practitioners, and specialists . Fig. 85. first time, find it possible to divide faradism into at least three distinctdoses, and place the current under comprehensive control. I know of no electrical appliance capable of attaining such the interrupters and vibrators—barring none, for I had the good for-tune to make comparative tests of a dozen or more of the best ones—have a limit which in no instance exceeds 10,000 interruptions perminute. This is from accurate measurement. A not less desirable feature of m) apparatus is the fact that all theplugs and movable switches—in fact, everj^thing governing the working ofthe apparatus—are before the operator, spread out upon a table, just asgood as the telegraphers switch-board and instruments are arranged. A~294 The Eiigelmann coil, too, is constructed with a movable core and bobbinslide, whicli graduates the rise and fall of the energy of the current as tobe least appreciable to tlie patient; and, so, violent shocks, the disadvan-tages of which we are aware, are avoided. In other respects the faradicdivision of the apparatus is built on the most accepted principles. The galvanic current is governed from the right side of the we have the pole-changer, the mil-am-meter, and the resistancemeasuring apparatus, of which I will say a word in explanation. Theknown resistance of a dozen coils, each governed by a movable shunt,is given. Thus, if the resistance of a patient or a part, as is so essential in thoughtful treatment bymeans of electrical energy,is to be calculated, the partis placed into the circuit andthe current as it flowsthrough is read upon themeter. The rheostat isnext thrown in, and thepart or patient cut out ofthe circuit. The knownresistance coils are then thrown into th
