On Monday evening last, a man named William Dempster, a juggler of inferior dexterity while exhibiting his tricks in a public house in Botchergate, kept by a person named Purdy, actually accomplished the sad reality of one of those feats, with the semblance only of which he intended to amuse his audience. Having introduced into his throat a common table knife which he was intending to swallow, he accidentally slipped his hold, and the knife passed into his stomach. An alarm was immediately given, and surgical aid procured, but the knife had passed beyond the reach of instruments, and now remains in his stomach. He has since been attended by most of the medical gentlemen of this city; and we understand that no very alarming symptoms have yet appeared, and that it is possible he may exist a considerable time, even in this awkward state. His sufferings at first were very severe, but he is now, when not in motion, comparatively easy. The knife is 9 1/2 inches long, 1 inch broad in the blade, round pointed, and a handle of bone, and may generally be distinctly felt by applying the finger to the unfortunate man's belly; but occasionally, however, from change of its situation it is not perceptible. A brief notice of the analogous case of John Cumming, an American sailor, may not be unacceptable to our readers. About the year 1799 he, in imitation of some jugglers whose exhibition he had then witnessed, in an hour of intoxication, swallowed four clasp knives such as sailors commonly use; all of which passed from him in a few days without much inconvenience. Six years afterward, he swallowed FOURTEEN knives of different sizes; by these, however, he was much disordered, but recovered; and again, in a paroxysm of intoxication, he actually swallowed SEVENTEEN, of the effects of which he died in March, 1809. On dissection, fourteen knife blades were found remaining in his stomach, and the back spring of one penetrating through the bowel, seemed the immediate cause of his death. Several women have adopted the profession of sword-swallowing, and some have won much more than a passing fame. Notable among these is Mlle. Edith Clifford, who is, perhaps, the most generously endowed. Possessed of more than ordinary personal charms, a refined taste for dressing both herself and her stage, and an unswerving devotion to her art, she has perfected an act that has found favor even in the Royal Courts of Europe. Mlle. Clifford was born in London in 1884 and began swallowing the blades when only 15 years of age. During the foreign tour of the Barnum & Bailey show she joined that Organization in Vienna, 1901, and remained with it for five years, and now, after eighteen years of service, she stands well up among the stars. She has swallowed a 26-inch blade, but the physicians advise her not to indulge her appetite for such luxuries often, as it is quite dangerous. Blades of 18 or 20 inches give her no trouble whatever.
