PECULIARITIES OF ACTION. 9 



A horse suffering from navicular disease goes uphill sounder than 

 he G^oes down ; the reverse is the case in laminitis. 



When an animal is lame behind, the disease is generally in the 

 hock ; when in front, in the feet of cart-horses, and in the ligaments, 

 tendons, or cannon bones of those which are used for fast work. 



When a horse goes lame on a fore leg without any perceptible 

 cause, and wears away the toe of the shoe, we may suspect that 

 foot of navicular disease. But if he goes on the heel, the pro- 

 bability is that he has either laminitis or ringbone. If the lame- 

 ness is behind and the toe becomes worn, we shall generally find 

 that it is due to spavin. 



Side-bones are chiefly confined to cart-horses, sore shins to race- 

 horses, and navicular disease to cab and carriage horses. Navicular 

 disease and occult spavin are rarely found in horses under seven 

 years of age. 



METHOD OF FINDING OUT WHETHER THE SEAT OF 

 LAMENESS IS OR IS NOT ABOVE THE FETLOCK.— Use 

 cocoaine in the manner described on page 608.
