It is almost always accompanied by a considerable diminution of size; the granulations and the atrophy generally commence at the edges, and the latter attains its extreme development at this point; the edges consequently appear very much thinned, and at last form a mere seam, consisting of cellulo-fibrous tissue, which is contained between two condensed laminae of peritoneum, and reflected over the convexity, or inverted into the concavity of the liver.
