lack and then in a yellow en-velope. This, however, must be done in a dark room, using only a goodruby light through which no white light will be admitted. In placing the plates in the envelopes, the film side must be towardthe front of the envelope so that the fold is closed on the glass side of Electro-Medicine, Electro-Surgery and Radiology 115 the plate. The glass side and the film side of the plate may be distin-guished, holding the plate at an angle toward the ruby light. The glassside reflects brightly and the film side is dull. If there is no light used,the surface is tested with the wet finger—the glass side slips and the filmside sticks. After placing the plate in the black envelope, this (envelopecontaining plate) is then placed into the yellow envelope in the sameway as in the black, placing the fold of the black envelope at the bottomof the yellow, so as to prevent the leakage of light through the folds.The plates enclosed in this manner may then be handled in daylight.

For the reason that black envelopes contain a certain amount of sod-ium hyposulphite, which causes deterioration of the film if the plates re-main in them for several days, it is advisable to place the plates in theenvelopes only a few days before they are used. The plates should be kept in the dark room or a safe and should notbe removed until the machine has been adjusted and the degree ofvacuum of the tube has been established. When the penetration of thetube has been established, the plate is placed film side toward the target(of the tube) on the table; the part to be radiographed is resting on theplate or is brought into as close contact with it as possible and the tubesome distance above, so that the target is directly over the center ofthe part to be radiographed. 116 Anthony Matijaca THE DISTANCE from the target to the plate is usually from 16 to 24inches, but the shorter the distance, the greater will be the magnificationof the image on
