Practical pathology; a manual for students and practitioners . g from the capsule into the substanceof the tumour, forming spaces (cs.) lined with flattenednucleated cells (e.), and containing, apparently, n<nhing butblood—coloured {) and colourless (/.)—corpuscles. may be seen shining through the capsule as a purple or dark claretcoloured patch. The patch may be single, and about a third of aninch in diameter ; or the growth may appear to be multiple. At thesite of the tumour there is a slight depression, in which there is a 298 THE LIVER mass which has the appearance of an extravasation of blood sharplydefined from the surrounding tissues, though it can be partiallyinjected from any of the vessels of the liver. On making a sectionjafter hardening a piece of the liver (§ 62 or 63) containing such anangioma, the tumour is seen to be rounded or wedge-shaped; it issharply marked off from the liver tissue, at first sight appearing littlemore than a mass of coagulated blood.

The bandsform a network, the spaces or meshes of which communicate withone another. In these spaces, under this power, a granular greenishmass (red blood corpuscles) is seen, with here and there a small pinkdot (a leucocyte). This blood fills the cavernous spaces
