ENLARGED GLANDS 2>2>7 The reader must imagine the patient with all these lines drawn onhis skin (they are, of course, readily removed with a little alcohol), inorder to appreciate how the examinations made from different sides con-firmed each other, and gave an exact indication of the size, position, andmovement of the dark mass. The X-ray photograph (Fig. 193) was taken somewhat later than thetracings; it shows the rounded border of the dark new growth, andbelow the growth the Hghter pulmonary area crossed by the ribs onboth the anterior and posterior wall of the chest; Hkewise in its lowerportion the outline of the diaphragm and the liver. I have had only a. Fig. 193. Daniel M. Radiograph taken with plate on front of chest and tube behind the curved outline of the dark mass above the light area corresponds to the outline seen on thefluorescent screen (Fig. 192, page 336). Below the light area, which is crossed by the ribs on front andback of thorax, is seen a portion of the diaphragm. (About one-third size of original.) portion of the outline of the new growth reproduced in the cut, for ifthe whole had been included a greater reduction of scale would havebeen necessary than was advisable. The striking features of this case are, first, the fact that so large amass in the thorax should give such slight physical signs; and, second,the readiness with which its outlines, position, and movement could befollowed on the fluorescent screen. The well-defined, rounded outline of the mass suggest
