CH. I.] ULCERS AND TUMOURS ON THE LIVER. 283 



mours on its fine surface, as well as with ulcers or 

 schirrus, which are all the effects of an evil state 

 of the blood, of over action, and probably of acci- 

 dents from external injuries, communicated by the 

 kidneys. 



We can easily conceive that the thin parts of 

 this large viscus may be diseased, and even inflamed, 

 without causing derangement of the biliary function, 

 further than increasing its action, and by thinning 

 the blood over much, it obtains more bile. The 

 animal then waxeth thin, though devouring his 

 food as usual for a while ; and we may ascertain 

 when this evil has begun by the state of his dung, 

 principally as to colour, which will then be of a 

 much deeper hue. As pale clung is a symptom of 

 suppressed bile, so is deep colour an indication of 

 a superabundance, that is caused by over action, 

 which is itself occasioned by the heat of the liver, 

 from some cause or other. One of these causes may 

 be " inflammation of the kidneys ;" or, it may be 

 occasioned by idcer ; and we set about ascertain- 

 ing which, according to the instructions set down 

 at page 185. In the latter case give the alte- 

 rative balls, the same as for inflamed liver, at page 

 280, according to the circumstances there discri- 

 minated ; but it never happens that a scouring is of 

 a dark colour, and a strong purgative would not 

 be required in this case, though the bowels should 

 be kept moderately open. When there is reason to 

 apprehend that the adhesion of the ulcer to the 

 intestines has taken place, as described at page 149 3
