Under this name Sotsevich describes an infectious disease of the 

 horse, which prevails in the Don province, and especially on rich, 

 low, damp lands. Before the appearance of any local lesion, the 

 horse goes very lame on one limb. Afterward there appears., 

 usually on the coronet or pastern, an area on which the hairs 

 stand erect, with elevation of the epidermis and the formation of 

 vesicles as large as barley corns, filled with a yellowish white 

 liquid and later with pus. Gangrene follows, extending from the 

 skin to the subcutaneous connective tissue, aponeurosis and ten- 

 dons, and forming large sores, one to two inches in diameter and 

 discharging an abundant yellow, foetid pus. The adjacent skin 

 takes on a yellow tint and sheds its hair and epidermis. The dis- 

 ease may extend into the interphalangean joints or under the 

 hoof, leading to offensive fistulse or evulsion of the hoof. If it 

 extends to the higher parts of the limb it becomes less destructive.
