THE URINARY SYSTEM 417 



parturition. The most prominent symptoms are that the animal 

 continually passes small quantities of urine, and has colicky pains. 

 Treatment — Externally. — Hot applications should be applied to the 

 loins according to the rules laid down for inflammation of the kidneys 

 (par. 717). Internally. — Sedative medicine should be given : for the 

 horse and cow, from 2 to 4 ounces of laudanum, with 15 to 25 ounces 

 of linseed oil ; for the sheep, 2 to 4 drachms of laudanum, in from 

 5 to 10 ounces of linseed oil. Warm water injections should also be 

 given by the rectum. 



724. Abscess in the Bladder is the formation of pus, or matter, 

 in the bladder, and sometimes occurs in the cow from injury done 

 to that organ in difficult cases of calving, more particularly if there 

 has been a breech presentation. Symptoms. — The symptoms are 

 continual paining and straining, with dribbling of urine. On ex- 

 amination (by the rectum), a swelling is felt, and on further examina- 

 tion (by the vagina), it is found to be in the bladder. The neck of 

 the bladder is usually very relaxed, so much so that the fingers can 

 be readily passed through it, and the abscess can be felt with the 

 tips of the fingers of the left hand, aided by the right hand in the 

 rectum. The operation for the liberation of the pus is rather tedious : 

 first, the catheter is passed into the bladder, to act as a director for 

 the insertion of a cannula ; the catheter is next withdrawn, and a trocar 

 introduced into the cannula, which is pressed into the abscess ; then 

 the trocar is withdrawn, and the matter escapes by the cannula ; while 

 pressing the abscess with the right hand in the rectum greatly helps 

 the removal of the matter. The operation being completed, the 

 bladder is washed out with tepid water and a small quantity of 

 tincture of iron. Should any constitutional disturbance arise, it 

 must be combated with fever medicine, and if necessary, hot water 

 blankets or porridge poultices can be applied to the loins {see Inflam- 

 mation of the Kidney , par. 717) 



725. — Calculi, or Stones, are occasionally found in the bladder, 

 urethra, and kidney ; they may form in the kidneys and pass down 

 the ureters into the bladder, or they may accumulate in the bladder 



itself. One or more stones may be found sticking in the neck of the
