or discolored pieces of the fatty cushion or the tendon still 

 remain, remove these with scissors, scalpel or curette. 

 Curette away all the cartilage from the inferior surface of 

 the navicular bone and remove any necrotic or inflamed,, 

 softened portions of the bone. In extensive necrosis of the 

 suspensory ligaipents of the heel and of the ligaments ex- 

 tending from the fetlock joint to the lateral cartilages, the 

 necrotic portions as well as the neighboring fatty cushion 

 with its numerous elastic fibres, must be resected. Incase 

 of purulent areas extending along the tendon and opening 

 above in the heel, draw through the tract a large strip of 

 gauze thoroughly saturated with tincture of iodine and 

 allow it to remain. If the suppurating area extends well 

 up into the heel without an opening, incise from above and 

 handle as preceding. Dress the wound as advised for 

 the quittor operation on page 164. In the absence of fever 

 the bandage remains in position for 12 to 15 days.

 ligature and after disinfecting the claws, rasp away the horn 

 on the lateral side of the diseased claw, especially at the 

 posterior part of it, until the horny wall becomes so thin 

 that it can readily be pressed in with the fingers. Anaes- 

 thetize. The corono-pedal articulation can be felt, about 

 3 cm. below the coronary band, by grasping the claw with 

 the left hand in such a manner that the thumb rests upon
