VIII. PRACTICAL APPLICATION OF THE RAYS The proper management of Eontgen ray work involves attentionto a number of details. It can be acquired only by a carefulstudy of the various parts of the apparatus and also of methods;unless these be mastered the operator may produce nothing butpoor results, and may speedily ruin the best and most costlycoil. In the following description an attempt has been madeto describe the process in a systematic manner, much as itwould be carried out in actual practice :

If the condenser be con-nected to the coil by means of wires fastened to binding screwson the base of the coil, see that the wires are firmly screweddown. Place the discharging-points of the coil opposite eachother, about h inch apart. The source of supply of the electric current having been testedas already described (p. 24), one end of a piece of thick, well-insulated copper wire, No. 12 B.G., should be firmly fixed inthe + terminal of the battery, and the other end securely fastenedto the binding screw on the coil; a second piece of wire shouldbe similarly fixed on the - terminal of the battery, and led tothe other binding screw on the coi
