hot water rugs to the loins. Feed on sloppy food, and keep the patient 

 perfectly quiet. 



If the animal recovers, he had better be fed ici the butcher, for the 

 trouble is liable to recur, and unremitting care woiildi be required to guard 

 against the effect of storms, extremes of tcmperatme, etc. 



II. Retention of the Urine, or Dysuria. 



Cause. — It may be brought on by eating acrid herbs, causing inflamma- 

 tion of the urinary organs, irritability and spasms of the neck of the 

 bladder. Most commonly, however, it is a symptom of some other dis- 

 ease, the pressure upon the neck of the bladder resulting from inversion 

 of the rectum, calculi, or other visceral trouble. 



How to know it. — Frequent but ineffectual attempts to pass the urine, 

 straining, and colicky pains ; the hind legs arc raised and moved about 

 restlessly, and the animal looks around towards the flank. 



What to do. — Give hot water injections by the rectum, (and in the 

 female by the vagina also) ; add to the injection one ounce of opium, or 

 three drachms of fluid extract of belladonna. Repeat these in fifteen min- 

 utes. If there is still no relief, the urine must be drawn off with a 

 catheter. With the female this is very easily done, the catheter being 

 inserted through the opening to the bladder, Avhich will be found on the 

 floor of the vagina, and about three inches from the external orifice. 

 With the male it is a far more serious operation, and, unfortunately, 

 retention of the urhie is far more common in the male than in the female, 

 owing to the peculiar formation of the urethra, a slight pressure on one

of the curves being sufficient to cause the difficulty. The operation nec- 

 essary to draw off the urine from the ox will be found described in the 

 chapter on operations. After using the catheter, give the injections pre- 

 scribed above, with a light diet and some linseed tea. for a few days.
