Each lobule is a small irregular or polygonal area, measuring from ^§-th t0 iVth of an inch in diameter, or 1 to 2 mm., with a partial covering of fine connective tissue, forming a delicate stroma. In the adult, the liver weighs from 3 to Z\ pounds, or about -^th of the body weight, and it is somewhat heavier in the male than in the female, its weight in the former being from 50 to 55 ounces and in the latter 43 to 48 ounces. The ratio to the body weight is the same in both sexes. In the foetus and child it is relatively very large and heavy. At birth it occupies the greater part of the abdominal cavity, and constitutes from ^th to TVth of the body weight. In the young foetus the ratio is even larger. Tlie average size of the liver may be briefly expressed as follows :—It measures in tbe trans- verse direction about seven inches (17*5 cm.); in tbe vertical, six to seven inches (15 to 17 "5 cm.); and in the antero-posterior, on the right side where greatest, about six inches (15 cm.).

The liver is capable of being greatly distended by fluid forced into its blood-vessels. Its surface then becomes tense, and the consistence of the whole organ becomes much firmer. Shape.—If the liver is hardened in situ and then removed from the body, it will be found to present a form which is fairly constant, but which is modified by the shape and size of the adjacent viscera, and hence shows minor variations in different individuals. If the liver has not been hardened, it does not retain, after removal, the shape and form which it had when it lay in the abdomen, but tend
