    Ccau carry on two operations at the same time, for whilst the separation is proceeding by the absorbents, the parts are forming themselves for suppuration. An abscess, during the time pus is accumulating, will make its way from the deeper parts to the sur- face of the body by absorption of the overlying integument ; and numerous small blood-vessels have their continuity interrupted without bleeding. In ulcers the natural texture is eroded or ab- sorbed, and here numerous cells flow away in the discharge. Blood-vessels, too, are frequently divided by ulceration without any loss of blood. In both abscess and ulceration there is evidence of two simultaneous operations—first, cell-growth,— and secondly, absorption or disintegration of the vascular-tissue without haemorrhage. Appearances are ver}^ different in an abscess as compared with an ulcer—because, in the former, the new matter, the new-growth, pus, being confined, its accumulation causes swelling, and this hides from view the loss of the existing texture by absorption, whilst, in the latter, an ulcer, the new matter having a free dis- charge, the loss or disintegration of the existing texture is the most prominent feature. Truncate an abscess or pustule, allow the pus to escape, and an ulcer with a soft pyogenic surface, or with granu-
