Fig. 23 shows the patient connected to the positive side of themachine, and he becomes positive by having the electrons with-drawn from him by the action of the machine in making theprime conductor positive, and, since it is in metallic contact withthe patient M, he will be made positive by conduction. In eithercase the patient M must be insulated by placing him on a plat-form P. (3) Indirect Sparks.—The arrangement for the indirect sparkis the same as for the static spray, with the exception that in theindirect spark the electrode is a ball instead of a point. Figs. 24 ELECTROSTATICS 55 and 25 show the arrangement of the machine, electrode, and patientfor the indirect static spark, negative and positive. A good-sizedspark will pass between the patient M and the electrode E. Like
