HORSES. 



135 



Symptoms. Frequency of staling; mingling of mu- 

 cus, or pus, or blood, with the urine ; a slight additional 

 heat felt when the hand is introduced into the rectum 

 and rests on the bladder, and the acute pain which that 

 pressure occasions, as shown by the shrinking of the 

 animal. 



Remedy. Sweat freely, rub dry, and give aloes as 

 physic ; only a mild dose, as the lower intestmes sym- 

 pathize with the sensitive state of the bladder. Give a 

 plenty of linseed tea. Give mild and warm injections, 

 such as water, or herb tea, as these come near the blad- 

 der, and serve as fomentations. In England, linseed tea 

 is injected into the bladder by means of Reed's catheter. 

 In case of mares, this may be done with a more simple 

 apparatus. 



INFLAMMATION OF THE NECK OF THE BLADDER. 



In this disease, there is a spasm of the sphincter muscle 

 at the neck of the bladder, closing the orifice, so that 

 little or no urine can pass. To determine whether there 

 is a difficulty in staling, from inflammation of the neck 

 of the bladder, or a suppression of urine from diseased 

 kidneys, the hand, well oiled, should be introduced into 

 the rectum. If there is inflammation of the kidneys, the 

 bladder can scarcely be felt under the gut ; but if the 

 neck of the bladder is inflamed, the bladder will be full, 

 and this will be evident from the protrusion upon the gut. 



Causes. A severe cold, irritability of the bladder gen- 

 erally, a stone pressing on or near the neck of the blad- 

 der, gravel passing through and injuring the urethra, or 

 the cruel and worse than savage custom of injecting into 

 mares a tincture or infusion of cantharides, or other pow- 

 erful stimulant, to hasten the periodical heat. Some- 

 times driving the horse long, without an opportunity to 

 stale, causes a spasm in the neck of the bladder, and is 

 unattended with inflammation. 



SyaiPTOMS. At first there -will be frequent discharges 

 of urine, then a gradual decrease, both in the quantity 

 and the size of the stream, and at length a total cessation. 

 The extended bladder can be plainly felt under the hand 

 in the rectum, rather tender and painful, but not hot.
