THE MICROSCOPIST. 



The " fatty liver," as it is called, is due to infiltration. 

 The ingestion of fatty aliments is followed by temporary 

 accumulation of fat in the portal blood, which is apt to be 

 deposited in the portal capillaries of the liver, which is 

 gradually conveyed to the central or hepatic capillaries of 

 the lobules, and thus to the general circulation. In mor- 

 bid conditions, as in tuberculosis and heart disease, we 

 find the morbidly fatty liver first infiltrated in the portal 

 zone as in Fig. 200.

In more advanced cases all the liver-cells become filled 

 and the bounds of the acini are effaced. Fat may occur 

 in the liver in connection with general obesity, or from a 

 failure of the oxygenating power of the blood, in which 

 case there may be general emaciation. 



5. Albuminous Infiltration. 



Albuminous infiltration, or cloudy swelling, consists in 

 filling the tissues with molecular albumen. It is regarded 

 by Yirchow as a nutritive irritation, or an incitation of
