Hadthe focus-tube been available in that instance, there can be littledoubt that the early invasion of the left lung could have beenequally well demonstrated. An x-ray photograph of the lungs, then,may afford valuable confirmatory evidence when combined with theinjection of tuberculin for diagnostic purposes. In one case the author was enabled to obtain a record of individualgrey miliary tubercles in the lungs of an infant that died from acutetuberculosis. The original radiogram was shown at the Portsmouthmeeting of the British Medical Association. Unfortunately mostof the sharp detail of the original is lost in the reproduction shownhere by the courtesy of the Hospital (see Fig. 163). One of the most constant and significant signs is the limitedexcursion of the diaphragm. Tubercular shadows, if the disease be

Where there is consolidation, how-ever, the shadows are more or less patchy, and darker than the ribs.In pleurisy the shadow is dark but uniform. The heart, it shouldbe borne in mind, may be drawn towards the affected side by thecontraction of the lung and its lessened expansion. The localization of diseased areas in the lung is now broughtwithin the reach of the surgeon, who has hitherto been hamperedin his attempts at lung surgery by the often misleading nature ofphysical signs. Supposing a shadow to be fairly defined, its exactposition could of course be ascertained by the ordinary methods ofstereoscopy and localization. The altered density of tissue may showin various degrees from a slight haziness to a dark shadow; whenextremely dark it may be due to pleuritic thickening and ad-hesions. In tuberculous c
