The international encyclopaedia of surgery; a systematic treatise on the theory and practice of surgery . edles, iron-wires, etc. They may easily be extemporized frompieces of telegraph wire by rolling up one end into a spiral form, filingthe other end to a point, and push-ing it into a piece of wood to serveas a handle. (Fig. 411.) In applying the cautery forhemorrhage, care must be takenthat the iron is heated only to adull red color; for, should it beraised to a bright red or whiteheat, it may defeat its own purposeby destroying the artery too exten-sively, or by bringing away theeschar stuck fast to the iron, thusleaving the vessel unclosed. Whenpracticable, the heated iron should be passed through a glass tube down to thebleeding orifice, in order to shield the surrounding parts from injury. Thelate Dr. George ]McClellan, of Philadelphia, in this way, introduced red hotwires of the largest size down the throat and up the nostrils, to check thehemorrhage from bleeding vascular tumors, with perfect safety. Fig. 412. Cautery-irons improvised from telegraph wire, afterBrandis. (Esmarch.). Tiemanns thermo-cautery apparatus. The thermo-cautery instrument is a very ingenious and useful contrivance,introduced by Paquelin, by which the cauterize) or platinum point may veryquickly be raised to a bright red or even a white heat, and may have the samedegree of heat kept up for any length of time without any difficulty is peculiarly well adapted for operative procedures in the mouth, vao-ina,and rectum. By attaching a blade to it, incisions that are bloodless may bemade, and with an ecraseur of platinum wire, tumors may be removed in abloodless manner also. In preparing the instrument for use (Fig. 412), the button-screw cap is tobe removed from the receiver, and benzine or gasoline is to be poured intoit until the wool which it contains is saturated with the liquid, but no morethan that. On replacing the cap, the receiver itself may be suspended froma button-ho
