Apeculiarity such as that of double high division of the brachialartery was well shown. In a later issue of the same journal (January 20, 1897), published some further illustrations obtained in asimilar way. They showed the arteries about the knee and theankle joint. The small muscular twigs and other minute brancheswere reproduced with the utmost fidelity. There can be no doubt that this method may now and thenafford a valuable means of showing in a graphic manner the.

As an instance of the latter, a perfect picture couldbe obtained of circulation by anastomoses, say, in a case whereduring life the femoral artery had been tied for aneurism, or in thestump of an amputated limb. Dr. Clendinnen adds that in one case he obtained from theliving body a good record of the popliteal artery. This observa-tion is valuable, and perhaps points to the time when a fullerknowledge of conditions in relation to results will bring the blood-vessels under command of the Kontgen-ray worker. MEDICAL AND SURGICAL APPLICATIONS 411 At a meeting of the Biological Society of Paris, June 11, 1898,M. Turbert* showed two radiograms, the first of which, taken froma dead body, showed clearly the radial and ulnar arteries : and thecourse of these arteries could be followed even where their radio-graphic
