Another use to which the alternating current may be subjected is to lightdiagnostic lamps. Perhaps this matter may seem a verj^ simple one to dwellupon at first thought, but upon further, consideration the complexity of thesubject will be appreciated. There isfrequent call for a wall plate or otherpiece of apparatus which will combine acurrent for diagnostic lamps among otherfeatures; this is an easy matter to arrange,regardless of whether the plate is to beused with either direct or alternating cur-rent; but especial stress should be laidupon the fact that a seperate contrivance,such as a large, heavy current graphiterheostat will prove more suitable to thepurpose. Another manner of using thealternating current to light small lampsis by using series lamps in connection toregulate the flow of current. A number of diagnostic lamp sets are on the. THE GUIDE 65 market which embody this principle, among which will be found a veryunique one, in that the small lamp is absolutely guarded against an excessof current; which may be accidentally encountered when used with a wallplate or other controller. What is a motor-generator^ and its use? Another method of utilizing the alternating current in electro-therapy,although in a rather indirect manner, is by transforming it to a direct cur-rent which may be employed in producing galvanic effects; a motor-dynamooutfit, so styled, is used for this purpose. The process of transforming thecurrent really amounts to developing power by passing the alternating cur-rent through a small alternating current motor; the shaft of this motor iseither geared or connected directly with the shaft of a small direct current
