INFLAMMATION OF THE PODOPHYLLOUS MEMBKANE. 137 



hoof, most evident in purulent cellulitis of the plantar 

 cushion. Forward pointing and weighting the heels, chiefly 

 or exclusively, suggests disease in the anterior half, particu- 

 larly the region of the toe of the hoof, as in founder (see 

 fig. 25). Swelling in the hollow of the heels or the coronet 

 and along the course of the flexor teudons is, as already 

 stated, of value in coming to a conclusion. (See page ).

Palpation. — The hoof-tester or the hammer reveals painful 

 spots, which, when cat out with the searching knife, are 

 found to be either red or black, occasionally yellow, and 

 matter, either thin, of gray or black color, or thick and 

 yellowish. One may detect separation of the sole from the 

 wall, or even of the wall from the laminae. The trace of a 

 misdirected nail or a foreign body, as a nail, etc., is found. 

 Increase of temperature in certain regions, as the toe.
