ization, while actinomycotic ulcers are treated witli iodide of

 Do ulcers play an important role in veterinary surgery ? 



They do not. Most of them yield readily to treatment, 

 excepting, of course, some of the specific ones, as those follow- 

 ing the breaking down of malignant growths (carcinoma), 

 farcy (its treatment is illegal) . 



Name the more important and more frequently met with ulcers 

 of the domesticated animals. 



In the dog, ulceration of the tip of the ear, cornea (dis- 

 temper), tip of the tail, stomatitis ulcerosa (tooth disease), 

 carcinomatous ulcer. 



In the horse, ulcers about the lower extremities, de- 

 cubitus (bedsores), carcinomatous ulcers, ulcers in the regians 

 exposed to harness pressure. 



Give the treatment of the healthy, indolent, fungous and 

 phagedenic ulcer. 



Healthy ulcer : Allow rest to the affected part. In case 

 disintegration is evident, hasten the separation of the dead 

 tissues by warm antiseptic poultices. As soon as healthy 

 granulations are obtained after removal of the slough most 

 any kind of dressing will heal a simple ulcer, as dusting the 

 parts with tannoform, tannic acid and iodoform (3:1), etc. 



Indolent ulcer : Healing can only occur by the produc- 

 tion of granulations, to be brought about by creating hy- • 

 perssmia. Soak the indurated edges for forty-eight hours by 

 a warm alkaline antiseptic poultice . Then incise the edges at 

 a right angle and dress antiseptically. These incisions favor 

 contraction and granulations will sprout in them. After two 

 days curette the whole ulcer until the parts bleed and sound
