particularly upon the loss of appetite and the immediate 
prostration, gradually increasing to a fatal termination. In 
our post-mortem examination we noticed extensive disease 
of lungs, with fatty degeneration of liver, sufficient to account 
for the frequent non-success of the treatment. 
The important question refers to the diagnosis of such a 
state of parts; so far as the liver is concerned, we take 
for granted that the existence of previous disease will be 
admitted; enlargement with fatty degeneration are not pro¬ 
duced in the course of the ten days or fortnight of the 
animaFs illness, during whicli he scarcely feeds at all. How 
long such organic affection has existed it may be impossible 
to conjecture, unless the whole of the animal’s previous 
historv were before the examiner, who would then be in a 
position to point out what kind of food, given at a par¬

Fat elements in some form, either starch, or sugar, or oils,

known to act in the production of such a condition; of this
