A system of instruction in X-ray methods and medical uses of light, hot-air, vibration and high-frequency currents : a pictorial system of teaching by clinical instruction plates with explanatory text : a series of photographic clinics in standard uses of scientific therapeutic apparatus for surgical and medical practitioners : prepared especially for the post-graduate home study of surgeons, general physicians, dentists, dermatologists and specialists in the treatment of chronic diseases, and sanitarium practice . Kieder in their one-secondradiographs of the thorax (and which is useful from the feet to thehead), proceed as follows: In a convenient part of the operating-roomerect two narrow vertical runners sixteen inches apart, in the groovesof which will slide like a sledge the feet of a wooden frame with afront board 14 x 17 inches in size. On this front board tack a plateof smooth sheet-brass one-sixteenth of an inch thick to serve as ametallic backing for all plates exposed. On each side of the movable 54 STUDIES m X-EAY DIAGNOSIS frame arrange a strap or means of steadying the part exposed in closecontact witli tlie film. On each side of the front of this frame arrangean adjustable piece to i^tain any size plate from 14 x IT down to8 X 10, with a narrow ledge below to complete the holder. Fromthe centre of the plate-carrier run a cord over a pulley in the topcross-bar of the apparatus with a counterpoise weight at the end soas to balance the exposing frame at any desired height to which it. Fig. 4.—Sliding frame plate-holder for exposures of the thorax by Von Ziemssens method described in text. is moved. Add a set-screw to fix it in position when localized for thepatient. From the most convenient side of the frame build out apermanent rigid arm for a tube-holder which will retain a fixed focusof the anode at right-angles with the exact centre of the frame andtwenty inches from the plate, so that all plates exposed mil be auto-matically centred without furt
