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 liver, 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.)
