DISEASES OP THE HOG. 203 



old. These deposits may form in the kidneys and 

 pass along the ureters to the bladder and out 

 through the urethra without causing any great 

 inconvenience, but should they stick and block up 

 the tubes they would cause very great trouble. 

 The symptoms would be irritation and retention 

 of urine; small stones may remain for a long time 

 in the bladder without causing any very great dis- 

 turbance; if such should be suspected the animal 

 should be fed for the market. I have met with a 

 few cases of prepucial calculi in the castrated hog, 

 caused by the urine running over the anterior part 

 of the prepuce, leaving a deposit of lithic acid 

 gravel, causing irritation and swelling of the pre- 

 puce (sheath), causing considerable disturbance to 

 the animal, such as loss of flesh and some stiffness. 

 The swelling of the prepuce and some stiffness 

 attracts the attention of the owner and an exam- 

 ination of the parts will reveal the nature of the 

 trouble. 



Treatment: Cast the hog on its side and remove 

 all the deposit with the fingers or a pair of forceps. 

 When this is accomplished it will be found that the 

 lining of the sheath is red and sore. After it has been 

 well washed and dried, mix one ounce glycerine, 

 one ounce water and thirty grains of tannic acid; 

 a little of this should be applied once a day until 

 the soreness and swelling have disappeared. 

 After it is cleaned out and dressed the animal will 

 be much relieved.
