ENLARGED TESTICLES. 



This condition is occasionally met with in the stallion, and the 

 testicle may enlarge to three or four times its natural size. It 

 may be due to a chronic inflammation, and may increase in size 

 very slowly. When this affection is recognized, the only success- 

 ful treatment is castration. 



PARAPHYMOSIS. 



By paraphymosis is understood protrusion of the penis without 

 power to retract it. It is caused by injuries directly or indirectly 

 received. Stallions suffer more frequently than geldings. Too 

 frequent service is often the cause, and we have seen it caused 

 by large stallions injuring the penis by serving small mares. 



Symptoms. The penis protrudes from the sheath and is much 

 swollen, and may or may not be very painful to the animal. 



Treatment. If taken in time it can generally be treated suc- 

 cessfully. If swollen to any considerable extent the penis should 

 be lightly scarified by cutting several small holes into it with a 

 sharp knife, to let some of the blood and serum ooze out. After 

 scarifying, bathe it nicely with warm water for an hour at a 

 time, and then a solution of alum water applied. The penis 

 should be supported by a bandage. Give one pint of raw linseed 

 oil as a drench, and give one dram of nitrate of 'potash morning 

 and night in damp feed. Feed plenty of bran mashes and no 

 corn. If it is caused by too frequent service, give one dram of 

 nux vomica every night for two or three weeks. If the case is 

 too far advanced before treatment is begun and mortification 

 sets in, the penis should be amputated (cut off), and the ecrasure 

 is the best instrument for the operation. (See Fig. 41.)
