Number 16. This cut shows the position of the 

 bones in forming the faulty articulation caused by an 

 extremely deep heel— yet with a little more depth at 

 front of foot than is proper— and showing that the 

 angle was kept pretty true until it came to the joint 

 formed by the cannon and the upper pastern bone. 

 At this point the proper angle was lost and the result 

 is a case of " Knee Sprung." This is one of the three 

 different causes that will be shown here for a '' Knee 

 Sprung" formation. As said before, just which way 

 the cant of the misplaced bones slant can be noticed 

 from the positions of any of the joints that " are out 

 of whack." Putting this foot back to its proper 

 proportions so that the articulation can be made to be 

 smooth and frictionless, as it can, will give nature 

 a chance to remedy the faulty action and the leg will 

 come back to its normal condition again. The author 

 has straightened badly "Knee Sprung" legs on 

 horses as old as 15 to 17 years, and had them keep 

 strong and straight in their limbs, and it can be 

 learned from these pages how easily it is of accom- 

 plishment. 



Number 17. Exhibits another form of foot found 

 on the " knee sprung " animal. The raising of the 

 front of the pedal bone gives a backward cant to the 

 smaller pastern, or coronary bone, which causes an 

 improper articulation all through the succeeding 

 joints to the knee, and it (the knee) will be uncom- 

 fortable in its action also. The pedal bone is thrown 

 out of position by the unwarranted depth of the front 

 of the foot in proportion to the depth of the heels. 

 Also number 22 is still another form; the toe is not 

 deep enough in comparison to the great depth at the 

 heels and the first articulation is seriously incorrect, 

 creating trouble through the succeeding ones. The 

 ankle joint in this case is quite likely, also, to be 

 seriously involved. 



These illustrations, like that also of No. 20, are 

 given to show that the improper position of the pedal 

 bone is productive of many and varied faulty articula- 

 tions, and that the effect of such on the first and suc- 

 ceeding articulations, is not the same in all cases.
