CHAP. I.] BLOODY URINE AND SUPPRESSION. 287 



treat it as such, and nothing else — nor by any 

 other name. If the pain and tension cannot thus 

 be ascertained, then " bloody urine" is caused by 

 obstruction in the liver. Another symptom that 

 may be relied upon is a stiffness of the hind leg on 

 that side which may be attacked first ; afterwards, 

 when both kidneys are affected, the animal becomes 

 stiff of both legs. This symptom does not occur in 

 " inflammation of the bladder" (i. e. its neck), and is a 

 good distinctive mark to go by, when we may be la- 

 bouring under doubt as to some other point of resem- 

 blance between the two diseases. In all stages of this 

 disorder, the horse stands as if he wanted to stale ; 

 straddling, and making the most exertion when he 

 voids the least urine (then always bloody), which 

 shows the destructive tendency of these efforts on 

 the gland itself. The consequences are, that the 

 kidneys waste away, and the disease communicates 

 to the bladder, until the final ruin — mortification 

 ensues. The practitioner, in this case, will not 

 fail to look at what is said respecting " stone and 

 other calctdi," zl few pages farther onward. In all 

 cases of constipation, turbid urine prevails, and that 

 obstruction being removed this symptom abates of 

 course. See Constipation page 183. 



" Suppression of urine" is also a sure indica- 

 tion of the genuine inflammation of the kidneys ; 

 that is to say, the capacity of secreting it is nearly 

 extinct, or it is performed with exceeding great 

 difficulty, pain, and danger. Whereas, in affections 

 of the bladder, the secretory function is not lost by
