ow on what do these shadows depend? Are they dueto tubercular consolidation or to patches of congestion of caseationor pleural adhesions or what? I have endeavored to answer thesequestions in the following way. On the screen before you is theskiagram of a tuberculous lung; nearly the whole of the upper lobewas caseous and breaking down. So we see that caseation throws avery dense shadow. The shadow, lower down, caused by gray andyellow tubercle, is nothing like so dense; still, as it might be said thatsome of this shadow is due to blood congestion round the tubercularconsolidation, I performed the following experiment: The lungs froma case of pulmonary tuberculosis were taken; one was soaked inwater for some hours to break up the blood-corpuscles, the vesselswashed out until the water came away colorless. Both lungs werethen skiagraphed, and I think you will agree with me that there islittle or no difference between them. Again, it has been asserted that the blood next to the bones is

Pl-ATE 145.—This Instruction Plate shows the Authors Examining Frame turned sidewaysand adjusted to an inspection of the chest, either back or front positions being equally engagedin the axis of the rays, which the frame holds fixed while the patient is shifted to bring suc-cessive fields and areas into the constant line of non-distortion. Letters A A in the intersect-ing angle of front and rear markers indicate the axis of the rays from the anode to the fluoro-scopic screen. Simply level the frame, insert the patient, clamp on the screen and light upthe tube and inspect the parts as taught. The photograph shows the patients right armthrown over the frame to get the shadow of the scapula out of the way, and the operator justready to place the fiuoroscope and begin the examination. The position of the camera failedto show the anode focus in exact line with the A A of the markers, but the plate suffices toteach the method.
