margins of the wouiid have become insensible they mil 

 not contract and heal. Eetum the protrusion, throwing 

 the animal on its back and quieting with opium, ether or 

 chloral if necessary. Then cover the opening with pads 

 and cover with a strong sheet wound round the abdomen 

 and laced tightly along the back. Keep the sheet in posi- 

 tion by bands carried from its anterior border to a collar 

 round the neck. Adjust and pad it carefully day by day 

 until all swelling and tenderness subside. 



Vaginal Hernia must be treated like eversion of the va- 

 gina. 



EVEESION OP THE EECTUM. 



The rectum protrudes naturally in passing dung but re- 

 turns immediately. If it remains and swells it demands 

 interference. Poorly-kept animals (dogs, pigs,) are hable 

 and it may be caused ia all from violent straiaing in work, 

 parturition, constipation, diarrhoea or dysentery. The 

 protrusion may be confined to a mucous fold at one side 

 of the anus or the entire gut may protrude to the length 

 of several feet. If recent it is httle altered, but if old, is 

 red, thick, softened or even ulcerated. The protrusion 

 must be emptied, cleaned and returned, the oiled finger or 

 arm (according to size)'being introduced into the gut and 

 through the constriction of the anus and. the other hand 

 used to strip it oS from this. The head of the patient 

 should be turned downhill and straining prevented by 

 pinching the back. In small animals with old protrusions 

 the part may have to be cut off close to the anus and a 

 few stitches passed through the edges to keep them in ap- 

 position. When returned a truss should be applied as for 

 everted uterus or vagina and a spare, laxative diet allowed, 

 nourishing or not according to the needs of the patient. 



PILES. 



These are dilatation of the veins on the inner and outer 

 sides of the anus, with exudation and fibrous thickening
