474 THE PRACTICE OF VETERINARY MEDICINE. 



If due to constriction of the prepuce, the latter may be sht 

 with a pair of scissors. Scarification may in many cases be 

 all that is necessary. If due to debility, feed well, and give 

 tonics, etc. 



Penis. — In connection with the penis — usually in con- 

 nection with the glans penis — growths of various kinds may 

 occur : some of them malignant in character. These are 

 most frequently met with amongst geldings, and are caused 

 by filth, bad care, debility, etc. In many cases an offensive 

 discharge takes place. 



Treatment. — Such growths should always be removed with 

 the knife. The wound thus made should be cauterized, 

 using argenti nitras, etc., until it becomes evident that 

 there is no probability of new growths springing up. 



Warts. — AVarts are the same when existing on, or in the 

 neighbourhood of the penis, as when existing on other parts

 midable operation, but is necessary sometimes. Cast the 

 patient, draw out the penis, and remove as much of the 

 organ as may be necessary, either with the knife, or the 

 ecraseur. If the former instrument be used, the operator 

 must ligate the bloodvessels to prevent undue haemorrhage ; 

 he should also pass the catheter before operating, and keep 

 it there a week or so, to prevent closing of the urethra by 

 cicatrization. Astringents, cooling lotions, and a laxative 

 diet will be all that are required. 



Penis, Excoriation of — Excoriation of the penis may be 

 caused by direct injury, such as may be sustained by a 

 large horse whilst covering a small mare, especially a mare 

 that has never been served before. It ma}' also be caused 

 by putting a horse to a mare too soon after foaling — the 

 mare having an irritant or putrid discharge from the
