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

 passed through the edges to keep them in apposition. When 

 returned a truss should, be appHed 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 dilatations of the veins on the inner and outer sides 

 of the anus, with exudation and fibrous thickening of the sur 

 .rounding connective tissue to form rounded swellings. They 

 ,ire reported in all domestic animals, but are especially commor, 

 in dogs. Melanotic tumours in horses are often confounded 

 with them. They are generally connected with torpid, inactive 

 liver, and an aggravated costiveness, straining, and the presence 

 of irritants in the large intestines. Dogs draw the anus along 

 the ground as in intestinal worms, pass hardened, blood- 

 streaked dung, with much straining, pain, and sharp cries, and 

 present around the anus bluish tumours which bleed freely if 

 wounded, and are connected with the terminal end of the guV 

 that hangs out through the opening. The general health rarely 

 suffers much. In other animals there is itching, switching, and 

 rubbing of the tail, with the characteristic tumours, and much 

 straining and difficulty in passing dung. Treat by mild laxa- 

 tives (sulphate of soda and common salt, 3 ozs. daily for the 

 large and 20 to 30 grains for the small quadrupeds ; or podo- 

 phyllin in one-fifth the usual doses, diily). Give moderately 

 of laxative, easily digested food, and maintain tone by bitters 

 (nux vomica). Locally bathe with tepid solutions of opium, 

 stramonium, and astringents (sugar of lead, alum, tannin, sul- 

 phurous acid, benzoated oxide of zinc ointment). Check 

 bleeding by solutions of sulphate of iron or matico. It is 

 sometimes necessary to remove with the ligature.
