Early-experiments upon gall-stones have been reported by Neisser, Goodspeed,and Cattell.^ A fluoroscopic examination for biliary calculi is thoroughly unsatis-factory, and until a skiagram is taken no absolute diagnosis should berendered. The method I employ is as follows : The patient rests uponthe table (upon his back) with the head-end raised and the foot-end ^ For full report of this case see Hemmeter, Diseases of the Intestines, vol. Medical News, Feb. 15, Fig. 1S9A.—Stomach and Intestines.—The patient stands in the opening of the table against itsupright portion. Plate 14 in. x 17 in. (35x43 cm.) Kidneys (floating), spleen and diaphragm mayalso be thus radiographed.
