Diseases of the Foot 481 



BtiTictures that aggravated affection of the sldn of the 

 heel in which red fungous growths appear. It may be 

 preceded by thrush and is due to the same general causes, 

 though it is also attributed to a parasitic fungus. It is 

 especially common in coarse lymphatic subjects. 



Symptoms. A rapid growth, from the frog or sole or 

 both, of a soft, unhealthy, spongy horn, the tubes of which 

 are unnatui'ally large, open and wanting in cohesion, so 

 that they often stand apart from each other, and have the 

 appearance rather of a fleshy material than of horn. If 

 cut down it may grow up to the same level in twenty-four 

 hours, and the enlarged viUi are reached and bleed long 

 before this would have happened in healthy horn. As in 

 thrush there is a most offensive discharge, and the disease 

 is very obstinate to treat. 



Treatment. Cut down the fungous horn till blood 

 comes, and the adjacent horn to the same level. Then 

 cover with tow soaked in tincture of muriate of iron and 

 apply firm pressure by slips of wood placed side by side 

 with one end of each resting above the web of the shoe 

 at the toe, and the other on a slip extending across the 

 bulbs of the frog and resting above the heels of the shoe. 

 This must be removed and the dressiug renewed at least 

 once in twenty-four hours. Should the course of improve- 

 ment seem lagging, change the dressiag for carboUc acid, 

 chromic acid, the mineral acids, sulphate of copper or 

 iroD, chloride of zinc, quicklime, chloride of antimony or 

 other caustic, resort being had to a new one in every 

 instance as the former seems to lose its effect. The re- 

 moval of the entire sole is essential to recovery in some 

 fjases.
