generated in the system by the use of food of a heating 

 nature, forming a chemical compound of an acrid quality 

 of urine ; stone in the bladder will also produce this 

 disease. Some persons are so absurd as to administer 

 the tincture of cantharides by way of hastening the 

 season of horsing the mare, which is almost certain to 

 inflame the neck of the bladder. Some practical men 

 advocate bleeding until the animal faints for this com- 

 plaint, which they say will cure it at once, but should 

 this not be done, the following should be given every 

 three hours : —Powdered opium one drachm, linseed-meal 

 three drachms, made into a ball or given in a drink. In 

 cases of mares being afflicted, the water can be drawn off 

 easily with the catheter, which would give great relief, 

 but with the horse it is difficult to pass the catheter, and 

 should not be attempted by anyone who is not a practical 

 man. Strong blisters should be applied at the same time. 

 In cases of stone in the bladder, we have no well-defined 

 symptoms, but the irregularity of the discharge of 

 urine with the occasional suppression of it, and fits 

 resembling spasmodic colic, are symptoms which 

 attend this disease and may lead us to suspect that 

 stone exists. To ascertain if it is really stone which 

 produces these symptoms, the horse should be thrown 

 on its back and the hand forced up the rectum, when 

 the stone may be easily felt, and if it is large then an 

 operation is necessary, which can only be performed by 

 a clever practical veterinary surgeon, but if the stone or 

 stones are small, they may be carried away with diuretics ; 

 the best in cases of gravel is carbonate of potass and 

 digitalis ; three drachms of potass and one drachm of 

 digitalis may be given three times a day.
