The sub- stance of each acinus — the tissue. Fig. 223.—From a Lobule of the Liver of Rabbit, in Avhicli blood-and bile-vessels had been injected, more highlv magnified than in Fig. 222. (Atlas.) b, Bile capillaries between the liver cells, which are well shown as nucleated polj'gonal cells, each with a distinct reticulum ; c, capillary blood-vessels. between the capillary blood-vessels—is composed of uniform polygonal protoplasmic epithelial cells, of about jQ^j-yth of an inch in diameter ; these are the liver cells. Owing to the peculiar, more or less radiating, arrangement of the capillaries, the liver cells appear to form columns or cylinders, also more or less radiating from the periphery towards the centre of the acinus. The cells contain particles of glycogen in various amounts. According to Brunton and Delepine, the amount gradually increases in the rabbit's liver after a meal, and reaches its maximum between the third and eighth hour. They also contain pigment granules, which, being derived from the disintegration of haemoglobin in the spleen, include.
