Text Appearing Before Image:

ratus can be disputed by another expertusing another apparatus; and the critic fortified by theory and in-trenched in confident ignorance can lay down still different rules forthe beginner. With the same apparatus the expert can produce twonegatives of good appearance, one with twenty seconds exposure andthe other with twenty minutes. But just as we have advanced fromthe minutes of Daguerre and of ambrotypes to the quick photographyof to-day so we will learn to regard X-ray exposures of minutes asthe crude necessity of pioneer work. At present few men seem toobject to two minutes as an ordinary exposure, but there are advan-tages in two seconds which will make two minutes obsolete as soonas plate-makers can mix an emulsion sufficiently rapid to X-rays.While many are not yet awake to the need of reducing these ex-posures to the plane of modern portrait photography, yet others ap-preciate the gain and are striving to bring it about through films ofnew composition unaffected by daylight.

Plate 37.—Inspection of lunss posteriorly. Sit the patient on a chair higher than theone to be occupied by yourself. Level the tube as shown in this instruction plate. Have thepatient raise both arms to remove the scapula from shading the pulmonary tissues, makeclose contact with the screen (or fluoroscope) in the axis of the rays at the standard distancefrom the tube, as here shown. The next step is to sit down comfortably in a chair that willbring the eyes easily on a level with the field to be examined, throw a black cloth over theoperators head and shoulders of the patient to enclose the open screen in darkness, and pro-ceed with the examination as taught in the text. The operator has a choice of using a regularfluoroscope, or the screen taken from the box as here illustrated, or a larger mounted screenfixed on a standard. The(^latter is shown in plate illustrating the Skiameter.
