Dr. Thomson says,* that in some experiments which he made on brute animals, (he does not say what animals these were,) he found a distinct layer of this coagulable lymph covering the wounds he had made, in less than four hours after they had been inflicted. Sir A. Cooper states six hours to be the time which, in dogs, intervenes between the infliction of the wound and the exudation of lymph. This period would seem, how- ever, to be aflPected by the nature and habits of the animal, which is the subject of our experiment; for in man it is considered, that a somewhat longer interval must elapse, even in favourable circumstances where the constitution is good, and the parts brought soon into contact and excluded from the air, before lymph is poured out upon the surfaces of the wound. Sir C. Bell states, in his Lectures on Sur- gery in the Edinburgh University, that in about seven hours after the infliction of the wound, the coagulable lymph is effused. But perhaps even a longer period than this will be nearer the true average. Sir A. Cooperf men- tions, that in twelve hours the edges of a wound will be firmly glued together; and if we allow a short time to elapse between the effusion of lymph and the agglutination of the parts, about ten hours may be regarded as the period which • Op.
