Treatment. As some mares refuse to make their water in har- 

 ness, they should be unhitched at suitable times for such pur- 

 poses. In all cases, take the animal out of the harness, spread 

 clean hay or straw beneath the belly, or turn the patient out on 

 the dung heap. Some accomplish the act by slow whistling, 

 others by pouring water from one vessel into another with a 

 dribbling noise. 



PARALYSIS OF THE BLADDKI!. 



Causes. It is associated with diseases of the .spinal cord, 

 broken back, where there is palsy of the tail and of the hind 

 limbs. 



Symptoms. When the neck of the bladder is affected, there is 

 constant dribbling of urine, which runs down the inside of the 

 thighs. When the neck is not affected, the urine is retained until 

 the bladder is very full, when it may be forced out with a gush. 

 This, however, does not entirely empty it, as it may still remain 

 half-full 



Treatment. Gentle pressure with the oiled hand, well in- 

 serted into the rectum, may force it out, but it is better to use 

 the catheter (Fig. 14) to draw the urine off. Give the fol- 

 lowing: 



Saltpetre 2 ounces. 



Iodide of potassium 1 J ounces. 



Powdered nux vomica 1^ ounces. 



Mix into twelve powders, and give one morning and 

 night in damp feed.
