This very simple andobvious mode of arresting the circulation through arteries, w^as employedlong since by Guattani and others, and with some degree of success ; butfrom the imperfect and often violent manner in which it was applied, itmore frequently failed than succeeded, and often caused considerablemischief. During the last six years, however, it has been revived by theDublin surgeons, Hutton, Cusack, and Bellingham, and has been ren-dered so safe, painless, and speedy a remedy, that it ought to supersede26 302 ANEURISM. Fig. the ligature in popliteal aneurism, and in fact in any case whatever inwhich it can be applied. It has been proved that it is not necessary com-pletely to obstruct the circulation of the artery at the point coraj)ressed,still less to excite the adhesive inflammation there so as to obliterate it;in fact, that a very feeble circulation through the aneurisraal sac is advan-tageous. It is found on dissection of cases treated in this manner, thatthe artery is obliterated at the site of the aneurism. The instrument employed to cause the pressure, may be either Signo-ronis tourniquet, (shown in tlie adjoining sketch,) an aVc of steel, with a joint in the middle, and a screwby whii-h the extremities of theinstrument are pressed toge-ther ;—or else a solid clamp ofsteel, having a wooden splintat one end, and a pad with ascrew at the other. By meansof either of these instruments itis evident that the pressure isconfined to two points only ofth
