cases this form of derangement is attended with irritation of 

 the kidneys or the bladder, and is made manifest by the frequent 

 attempts of the patient to urinate. The dung in the majority 

 of cases will be scanty ; at times nearly black, . and at other 

 times clay-coloured, and in hardness and form not unlike those 

 balls of wax used by shoemakers. 



If the affection has existed for some time, the patient loses 

 flesh, becomes weak, and is readily fatigued. In other cases 

 the animal is affected with a loud, dry, sounding cough. The 

 dung occasionally contains a few small worms. 



In the more severe forms of Indigestion the hair will peel 

 away in patches from various parts of the body. The general 

 movements of the animal will be listless and indifferent ; the 

 appetite bad; and the mucous membrane of the mouth dis- 

 agreeable, pasty, and covered with minute yeUow-coloured 

 spots.
