FATTY LIVER. 699 



cised, it seems often associated witli periodical attacks of 

 hepatic congestion, and where the organ acquires considerable 

 dimensions it seems largely operative in favouring extravasa- 

 tions and ruptures. 



Its existence, although not absolutely determined, may often 

 be suspected from the defective manner in which the liver 

 performs its functions, from the history of the animal, and 

 from the recurrence of what are apparently congestive attacks. 

 It is only likely to prove of serious moment when the invasion 

 of the cell-structures with fatty material is such that their 

 normal powers are considerably interfered with. 



The management of such instances of alteration of structure 

 must proceed upon attempts to remove the causes which are 

 most hkely to operate in this abnormal development and depo- 

 sition of fat. For this object it will be needful to enforce more 

 natural conditions of dietary and location, with a some what more 

 active life, and, if need be, by the exhibition of saline aperients. 



III. Albuminoid or Lardaceous Liver. 



This condition, known also as amyloid liver, often enough 

 seen in making after-death examinations of the horse, although 

 we may not be able with sufficient accuracy to distinguish the 

 clinical phenomena which accompany it, and to differentiate 

 these from other indications of structural change of the sohd 

 organs of the abdomen, may yet not be confounded in these 

 examinations with the altered condition of the same parts 

 just spoken of. As in the state of fatty change, the viscus 

 may or may not be enlarged ; but when it is so, the enlarge- 

 ment may be distinguished from the increase in bulk of the 

 fatty by its increased specific gravity. The colour may not 

 be so markedly different, but the consistence is distinctive. 

 In this albuminoid change the gland possesses much resisting 

 power, is not easily broken down, and when cut with a knife 

 feels firm, while the cut surface is rather glistening and dry. 

 The adventitious material deposited, probably appears first 

 around the minute radicles of the hepatic and portal vessels, 

 encroaching upon the cell-elements of the lobules, amongst 

 which, at first, they may still be distinguished. Its true 

 chemical characters are not well made out. 



This condition, although invading the whole or greater por-
