three quarters of an inch at 

 the pyramidal process.or front 

 of the joint. Fig. ?80 is a 

 bottom view of the same kind 

 of bone, and was obtained of 

 the Columbia Veterinary Col- 

 lege. Being engraved from 

 a photograph, it did not Work 

 up so well. Instead of being 

 flat, as it appears, the outer 

 edges were bent upward over 

 a quarter of an inch, with the 

 edges ragged and broken. 



I include also a specimen 

 showing effect of inflamma- 

 tion' by the pressure of the 

 toe-calk and excessive rasp- 

 ing of the wall. These re- 

 markable changes of structure in the foot generally, especially in 

 the pedal bone, when compared with that in a state of health, we. 

 see to be very great, and explain the destructive effect of inflam- 

 mation when allowed to con- 

 tinue for any 1 length of time. 

 Reference can also be made to 

 the many interesting speci- 

 mens following the section on 

 " Navicular-Joint Lameness " 

 showing this. Many of these 

 specimens will show not only 

 the navicular, but the outer 

 edge of the pedal, bone to be 

 fractured. 



In some extreme cases where 

 inflammation runs high,' and is. 

 allowed to continue very long, 

 this separation of the wall from 

 the internal structure may be 

 continued so far as to cause 

 ulceration of the coronet and 

 loss of the entire hoof ; but this is rare. 



There is no cure for chronic founder. All that can be done is

of Form in Pedal Bone,— the Effect ol 



Inflammation.
