tlm tea. Soon the inflammatory symptoms will subside, the patient 

 will manifest some relief from pain, and the color of the urine will 

 change, become lighter and thicker in consistence. We then dis- 

 continue the above treatment, and administer one ounce of fluid* 

 extract of buchu, morning and evening. This treatment, aided by 

 rest and good nursing, usually completes the cure. 



Should it be suspected that the animal has a fit of pain, caused 

 t bv the "gravel," or passage or presence of urinary calculi, then 

 two irachms of muriatic acid should be mixed in the ordinary 

 drink, every time the animal is watered. He should also have a 

 email quantity of powdered slippery -elm or flaxseed mixed with 

 the food. Horses the subjects of urinary calculi pass urine which, 

 on being caught in an earthen vessel, deposits phosphates and other 

 earthy matter. When this occurs, and the animal has a fit of pain 

 Dr gravel, we may infer, in the absence of more positive proof, that 

 urinary calculi are present in some portion of the urinary apparatus. 



Inflammation of the Bladder (Cystitis). 



The principal symptom of inflammation of the bladder is fre- 

 quent urination, accompanied by straining and pain. Sometimes 

 the urine dribbles away, involuntarily or not, as the case may be. 

 It appears that the least distension of the bladder causes pain; 

 hence the effort to keep it empty. The urine is usually high- 

 colored, or, rather, of a dull red color. The animal stands with 

 his hind limbs widely separated. The treatment is precisely the 

 same as that just recommended for inflammation of the kidneys. 



Stone in the Bladder. 



One very remarkable symptom attending the presence of calcu- 

 lus, or stone in the bladder, is, that after the urine is voided there 

 comes a painful sensation, which causes the horse to groan. This 

 is caused by the walls of the bladder coming forcibly in contact 

 with the calculus, which is now a foreign body. Occasionally the 

 horse is urinating a full stream, when, all at once, the stream is 

 suddenly arrested, the animal still straining until urination again 

 commences. This is a pretty sure sign of stone in the bladder. 

 Stones that have been taken from the bladder, after death, present 

 a highly -polished surface; hence they do not produce that amount
