In large wounds when important vessels are divided, we shouldinvariably apply a ligature to both the cardiac and distal orifices,for if this precaution be neglected, as soon as the collateral circula-tion is established, bleeding from the distal orifice will certainly takeplace. The same rule holds good when an artery (that is, a largeone) is merely wounded or punctured. A ligature in such casesshould be applied both above and below the solution of it was the practice to divide the vessel between them, butthis is unnecessary. When the vessel is small, however, we mayoften save time and trouble by merely cutting it entirely across, sothat the natural hemostatic process may take place in each extremity. Fie. [Diagram of Anastomosing Circulation.] In oblique wounds the vessels are divided in such a manner thatit is often difficult to apply the ligature properly, but we shouldalways draw the orifice well out from the surrounding tissues, andtie above the oblique wound in the artery. It is well known that in lacerated wounds, even when large vesselsare wounded, the hemorrhage is comparatively trifling,—and when aninexperienced surgeon is called to such a ease, and finds the arterieslying flaccid and pouring out no blood, he is disposed to trust to theefforts of nature alone, and leaves the vessels unsecured by ligatureor any other means. But although nature is occasionally competent tothe task, the practice of leaving the matter entirely to her, is fraughtwith danger; for as soon as reaction takes place, the partially para-lyzed vessels acquire a portion of their wonted energy, and oftenbleed profu
