This obstruction is sometimes quite marked andaccompanied by a genuine catarrhal jaundice, with discolorationof the entire body, due to the absorption of coloring-matter fromthe bile and deposit over the entire carcass. If an examination be made of a stained section of the liver underthe microscope it shows changes here very similar to those whichwere found in the spleen, but not nearly so well marked or individual liver cell is markedly swollen and stains poorlywith the laboratory stains. The nucleus of the cell is often frag-mented, and quite a number of cells are found in each lobule whichshow complete destruction. The blood-vessels at the center of.

White.) and around the margin of the lobule are dilated and filled withblood, with here and there a blood-clot or thrombus seen in theblood-vessel. In some of the cases with high fever there is, in addition tothis parenchymatous degeneration, a well-pronounced fatty de-generation of the liver. In these cases fat-droplets appear withinthe cell, and the entire appearance of the liver is greasy and yel-lowish, the cut surface often dripping an oily, fat-like fluid whencut across with the knife. Changes in Kidneys.—It is in these organs that we find thegreatest uniformity of lesions and the most constant presence ofchanges typical of the disease.
