let ray applications. I cannot, however, endorse such views.To me it does not seem plausible that any one machine can give all of thesevarious currents with equal degrees of satisfaction. For heavy work andto meet the exigencies of the Eontgenologist, I believe that specialapparatus adapted for each particular purpose is indispensable for theaccomplishment of the best possible results. B. Installation. It remains to give a brief resume of the arrangement and manage-ment of the different parts concerned in the production of a skiagraph.The first essential is to determine the nature of the current available. THE EONTGEN EAY APPAEATUS. 195 The coil cau be energized by an accumulator or by the continuous oralternating cm-rent from the street supply. In the latter instance thetransformer is necessary to reduce the enormous voltage. Some place thecoil upon the table ; my own preference is to rest it upon a shelf attachedto the wall, thus space is saved and the operator is kept away from the

The latter method is prevalent in Germany. The con-trolling apparatus (the interrupter, rheostat, switch-board, etc.) shouldbe within easy reach. After installing the coil, the source of current canbe connected with it by the use of the switch-board. The switch-boardis provided with several binding posts, the latter being connected with 196 ELECTEO-THEEAPEUTICS.
