72 DISEASES OF THE HOG. 



but sooner or later the structure of the liver be- 

 comes impaired. 



Atrophy. This is exactly the reverse of hyper- 

 trophy and very soon deranges the system, causing 

 death. 



Induration. The liver often acquires an in- 

 crease in its density and hardness from depositions 

 or new formations in its substance. 



Softening. This is often the result of inflamma- 

 tory action, but it may also occur without this 

 cause. 



Fatty liver. This is an adipose degeneration of 

 the liA^er, which usually increases in size. The 

 weight is not increased in a degree corresponding 

 to the enlargement. The characteristic hue of 

 fatty liver is a pale yellow or cream color, diversi- 

 fied by brownish, orange or reddish spots. It is 

 softer than a healthy liver. When cut it has a 

 brownish or pale yellow color, which is usually 

 modified by innumerable red spots. It has a 

 greasy feeling between the fingers. 



Waxy liver. Pathologists now believe it to be 

 the result of a peculiar degeneration or deposition 

 having no resemblance whatever to fatty matter. 

 The liver is much enlarged and at the same time 

 denser than in health. It is usually of a pale or 

 fawn color, but sometimes red from congestion. 

 It is tough in texture, and when cut presents a uni- 

 form compact, smooth, somewhat shining or trans- 

 lucent surface, pale or yellow, and not unlike the 

 rind of bacon or yellow wax. (Wood.)
