unthrifty aspect : if lie stands for a few hours in the stable the 

 limbs (particularly the hind ones) swell considerably. The skin 

 of the heels will crack, and lameness will ensue ; and from 

 these cracks will exude an offensive, greasy discharge. If

 luded to as being present in the ulcerative stage, become 

 lost, and in their place the fleshy growths become not only 

 larger, but more numerous ; while, from their surface arise 

 innumerable points of a bright red colour, which readily
