 is obstructed, and active inflammation is set up, that there must 

 not only be great local but general disturbance, and that it is of 

 the greatest importance to relieve this as quickly as possible, if re- 

 sults would be prevented, which would destroy the health and 

 mobility of the foot. The inflammation is primarily limited to 



1. Transverse section 

 of the hoof. 



2. Horny laminae. 



3. Vascular laminae. 



4. 5. Small cells be-

 the old practitioners. I include it mainly because I know of its 

 effectiveness from personal experience. If the case can be treated 

 as soon as the disease begins to develop, bleed from the neck vein 

 from four to ten quarts, according to the size and condition 

 of the horse ; that is, if the horse is large and fat, and 

 consequently full of blood, and the attack severe, then the larger 

 quantity mentioned may be taken. Afterward give a purgative
