of the surrouiiding connective tissue to form rounded 

 swelliags. They are reported in all domestic animals but 

 are especially common in dogs. Melanotic tumors in 

 horses are often confounded with them. They are gener- 

 ally connected with torpid, inactive liver and an aggra- 

 vated 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 tumors which bleed 

 freely if woimded and are connected with the terminal end 

 of the gut that hangs out through the opening. The gen- 

 eral health rarely suffers much. In other animals there 

 is itching, switching and rubbing of the tail with the char- 

 acteristic tumors and much straining and difficulty in pass- 

 ing dung. Treat by mild laxatives (sulphate of soda and 

 common salt, 3 ozs. daily for the large and 20 to 30 grains 

 for the smaU quadrupeds ; or podophyllin in one-fifth the 

 usual doses, daily). Give moderately of laxative, easily- 

 digested food and maintain tone by bitters (nux vomica). 

 Locally bathe -nath tepid solutions of opium, stramonium 

 and astringents (sugar of lead, alum, tannin, sulphurous 

 acid, benzoated oxide of zinc ointment) . Check bleeding by 

 solutions of sulphate of iron or matico. It is sometimes 

 necessary to remove with the Kgature. 



FISTULA IN ANUS. 



This is a communication between a suppurating sore and 

 the terminal part of the rectum. There are usually two 

 openings, one into the gut and the other close beside the 

 anus. The rational treatment is to remove any foreign 

 body or other cause of irritation and then passing an india 

 rubber cord through the canal, to bring the end from the 

 internal wound out through the anus and, stretching the 

 iTibber, to tie both together after which by its elasticity it 

 slowly cuts its way through, while the wound steadily 

 heals behind.
