A manual of practical medical electricity : the Röntgen rays and Finsen light . rent supplied to the lamps be a continuousdirect one, it can, by being passed through suitablerheostats, be used for galvanization, for working an induc-tion coil, and for light and cautery. If the current be an alternating one, it can be passedthrough a transformer, and, galvanization excepted, canbe used for the same purposes. Apparatus for use with Direct Currents from the Main. A leading principle must be never to place the patientin direct series with the mains, no matter how great theintercalated resistance.

A leading principle must be never to place the patientin direct series with the mains, no matter how great theintercalated resistance. The wires that pass to the patientshould form part of a branch circuit or shunt to the maincircuit (see p. 87). The main wires should be connected together througha coil of resistance wire and a lamp of a resistance suffi-cient to reduce the current to manageable dimensions,and then a little of this current should be tapped off foruse with a patient by a branch wire. Under these circumstances no possible danger or riskto the patient can be occasioned. Faradic Electricity 123. Fig. 74.— Portahle Switch-board. AdjustableRheostat J Connection Iwith main I
