108 NOx\-SPECIFIC OR GENERAL DISEASES 



probably occurring through some abrasion or small wound in 

 the skin. 



The local symptoms are swelling, tenderness and lameness 

 in the affected limb. The animal may refuse to support its 

 weight on the atlected limb. The lymphatic glands in the region 

 are swollen, and the swelling of the limb pits on pressure. In 

 the chronic form of the disease, the regions of the cannon and 

 foot remain permanently enlarged, and the swelling is more 

 firm than it is in the acute fonn (Fig. 24). 



The general symptoms are high body temperature, rapid 

 pulse and the partial or complete loss of appetite. 



The following treatment is recommended: Exercise is indi- 

 cated in cases that are not sufficiently advanced to cause severe 

 lameness, or inability to use the limb; rest and the application 

 of woollen bandages wrung out of a hot water solution of liquor 

 cresolis compound are recommended; Epsom salts in one-half 

 pound doses may be given and repeated in two or three days ; a 

 very light diet of soft feed should be given; liniments should 

 not be applied until the soreness in the limb has subsided; 

 iodide of potassium may be given twice daily with the feed.
