PLATE XIII. 



LAMINITIS OR FEVER IN THE FEET. 



A longitudinal section has, in this Plate, been made of the near fore foot, 

 from the fetlock downwards, of the Colonel's old charger, whose case is 

 given in detail at page 421. 

 It will be observed that the coffin-bone (a), which, had it been in its normal 

 or natural position would have lain slanting parallel to, as well as in 

 close apposition with, the wall of the hoof (&, c), has its toe (d), instead 

 of heing advanced to c, descending and resting upon the middle of the 

 sole, which, from the pressure of it, has bulged (at d), or, as farriers say, 

 become pumice. For the further explanation of this, turn to page 424. 

 The dislocation or tilting of the coffin-bone upon the sole, necessarily causes 

 a space within the foot between it and the wall of the hoof (e,/). This, 

 we find, becomes filled up with a sort of callus, which in the course of time 

 undergoes a gradual transformation into horny substance : as is intended 

 to be shewn by the yellow tint the drawing exhibits in the middle por- 

 tions of the callus.

h, Section of the coronet bone.
