THE MODERN HOUSE DOCTOR. 347 



having here and there deep gangrenous ulcerations. Thus did 

 the disease progress (apparently unchecked by medical treatment, 

 which had often proved successful) until the eleventh day from 

 the time of the injury, when, on making an effort to get up, a 

 complete separation of hoof from foot took place. Mr. D. im- 

 mediately ordered the animal to be put out of his misery, and 

 he was accordingly destroyed. This disease we have termed 

 inflammatory gangrene ; and although it rarely runs so rapid a 

 course, or attains so malignant a type, it is the one commonly 

 known as foot rot. 



Ordinarily, and in other than the cold season, puncture of the 

 foot, by nail or otherwise, is followed by healthy suppuration 

 and discharge, and the parts resume very nearly their original 

 condition ; but in the case just alluded to, the suppuration was 

 from the first unhealthy, and attended with a positive loss of 

 laminal continuity, ulceration, and gangrene. 



Treatment. — It is useless to lay down any particular plan of 

 treatment, for that must depend on the nature, stage, and inten- 

 sity of the disease. The principal local remedies are, — 



1. Antiseptics. — Pyroligneous acid, charcoal, chloride of soda, 

 and lime. 



2. Astringents. — Tincture of muriate of iron, sulphate of zinc 

 and of iron, bayberry bark, gum catechu. 



3. Remedies to relieve Pain. — Chloroform, sulphuric ether, 

 tincture of Indian hemp, infusion of hops or poppy heads. 



4. Constitutional Remedies. — Tonics and alteratives. (See 

 Medicinal Preparations.) In cases that indicate poultices, substi- 

 tute fir balsam. 



CORNS. 



Corns generally make their appearance in the inner heel, 

 within the bar and crust, at or near their junction. We find 

 that a great number of horses are afflicted in this way ; and it is 

 supposed that an imperfect system of shoeing has more to do 

 with the production of corn than any thing else. The following 

 article from White's Dictionary may possibly furnish the reader 

 a better idea of the nature and treatment of corns than the au- 

 thor of this work can give : —
