Causes.— They are very often the result of keeping horses 

 standing in damp or filthy stables. Clipping the hair from off the 

 legs is regarded as a very serious cause of scratches, as it leaves 

 the skin so bare that it cannot as readily resist the effects of ir- 

 ritants of any kind as when protected by its natural covering; but 

 the" most common cause is the habit of washing the legs with cold 

 water, and not drying them thoroughly afterward. The sebaceous 

 glands in the hollow of the pasterns become inflamed, their secre- 

 tion is increased, the skin cracks, and discharges an ichorous matter. 



Symptoms. — They usually cause lameness, more or less severe, 

 according to the severity of the attack, always most painful for 

 the first few steps. The hollows of the pasterns are swollen, red.
