It seems to have done its work by destroying the mucous membrane and to have left the field for miscellaneous bacteria. Other portions of the digestive tract are not affected. The secondary lesions are found in the liver, although in some cases they do not appear. The organ itself is enlarged to probably twice the normal size. Over the surface are distributed roundish, discolored spots, distinctly demarcated from the sur- rounding tissue. These may be distributed uniformly over the whole surface of the liver or they may be limited in number to a few. They vary from 3 to 15 mm. 'Al diameter. Several types of these spots appear corres- ponding to different conditions of the diseased tissue. We have in the early, most active disease process sharply defined circular areas of a lemon yellow, or a neutral gray or of an ochre yellow color. The spot is not homogeneous in structure, but made up of a delicate network of grayish yellow, dead tissue. In nother class of spots there is a mottled brownish color which contrasts only slightly with the surround- ing liver tissue by its darker color. It may contain a central yellow nucleus of dead tissue and a narrow outer border of the same character, or the border may be a dark brownish circular line. The entire spot has an indistinct ap- pearance and is flattened or Fig. 73. liver showing necrotic foci. even slightly depressed below the surface. In some cases they are uniformly whitish and shade off somewhat gradually into.
