This occurs in two distinct forms. We have already become acquainted with one in the shape of adipose deposition, or infiltration of the hepatic tissue with free fatty matter; the second is very unusual, and appears as a lipomatous morbid growth of a rounded or lobulated form, and rarely larger than a pea.

3. Cavernous Tissue

This is remarkable from its frequent occurrence in the liver. It resembles the tissue of the corpora cavernosa, and is commonly found in the peripheral substance of the liver only; from its dark-blue color it shines through the peritoneum, and the affection is therefore recognized on the external examination of the organ. It varies in size, from that of a hemp-seed or pea to that of a hen's egg, and more; is generally irregular in form, and its cells contain a large quantity of dark blood; a connection may be always traced between the latter and some larger portal vessel. According to the amount of blood contained in the compartments, these are found in the dead subject projecting beyond the surface of the liver, or collapsed and sunk. Sometimes they are single, sometimes numerous.
