    ihe external undivided. And it is in consequence of this fact, that the circular ligature, especially when small twine is used, as being the most proper for easi- ly rupturing the two internal coats of the artery, is considered as the best qualified for producing the most speedy and firm closure and obliteration of the arterial tube. But from this very fact, the rupture of the two internal coats, with regard to which there can be no doubt, it is most evident, that, at the first instant after the operation, the whole impulse of the circulation is supported merely by the external cellu- lar coat of the artery. Nature, adds this author, comes to the assistance of art. There is first form- ed within the cavity and on the orifice of the artery the clot of blood, which, during the first minutes after the operation, resists the impetus of the blood; then the adhesive inflammation ensues in all the three coats of the artery, in consequence of which a con- siderable quantity of coagulable lymph is effused without and within the artery, and also between the layers of these coats; then a portion of this lymph is employed in cementing together the edges of the divided internal coats, and in agglutinating firmly the coagulum to the internal parietes of the arterial canal; the other portion of coagulable lymph serves to thicken the coats of the artery, as well as to glue its external surface to the cellular substance, and to the muscles from which it had been detached. The rupture of the internal and middle coats of the artery occasioned by the ligature, according to this author, far from being a circumstance unfavourable to the speedy and firm union and complete closure of the artery, is rather, in his opinion, most favour- able, in so far as the internal wound made in the ar- tery, like a strong stimulus, accelerates over the
