Since the employment of the intralaryn-geal applications in this case, the writer hashad the opportunity of using the radivmi cap-sule in an advanced case of carcinoma of thelarynx, where a tracheotomv had been per-formed for the relief of obstruction tobreathing. In this case, it was difficult to in-troduce the bougie through the tracheotomyopening up into the larynx. Acordingly, thetracheotonn- tube was reinserted with thetracheal end pointing upward, this permittingthe bougie to pass upward into the larynx. This procedure had to be performed expe-ditiously, inasmuch as the patients respira-tions were, of necessity, cut off. While the observations on the effect of thetreatment of carcinoma by the radium cap-sule are as vet incomplete, the fact remainsthat it is perfectly feasible to retain in thisway anv desired cpiantity of radium in inti-mate contact with the diseased tissue for anylength of time 1.

OBSERVATIONS ON THE BEHAVIOR OF THE NORMALPYLORIC SPHINCTER IN MAN* By C. W. McCLURE, , and L. REYNOLDS, BOSTON, MASSACHUSETTS Tf XPERIMENTAL studies on the physi--- ological factors influencing the motorfunctions of the gastro-intestinal tract andthe relation of these motor phenomena to thedigestion and absorption of food productshave been largely carried out on animals. Butthe results obtained from such studies can beapplied only in a general way to the phys
