152 THE STOCK owner's ADVISER, 



■while running, suddenly falters and pulls dead lame. Soon there 

 will be great heat around the coronet, and great pain manifested. 

 The animal is unable to mark the limb. Xothing can be done 

 except to rest the animal and endeavor to combat inflammation. 

 It is frequently an act of mercy to destroy the animal. 



NAVICULAR. 



The na\acular bone may be fractured in two ways — first, by 

 direct jouncture, as when a nail penetrates the frog; secondly, 

 when it has been nearly worn through by caries or chronic navi- 

 cular disease. Fracture of the navicular bone is hard to diag- 

 nose. The history of the case must be taken into account. When 

 the bone is punctured by a nail, and broken, the discharge will 

 be of a bloody nature, giving it a dirty red hue and fetid odor. 

 When the fracture is caused by chronic navicular disease, the 

 horse is generally found to have been lame for some time, but 

 serviceable. All at once he becomes helplessly lame and unfit 

 for further use. This form of fracture oceups very often after 

 the operation of neurotomy, both tendon and bone giving way, 

 and the fetlock coming to the ground. Inflammation and suppu- 

 ration are the results ere reunion may take place. 



BROKEN RIBS. 



The causes are direct violence, such as kicks from other 

 horses and blows. In simple fracture there are no symptoms pre- 

 sented and no treatment necessary. The compound fracture is 

 the only kind that generally comes under our notice. The rib 

 may penetrate the lung and cause jmeumonia. 



Treatment. — To find out whether the lung is punctured, and 

 if the fragment or fragments of bone are displaced, and to re- 

 place them in their j)roper position. All this may be done by 

 introducing the finger into the wound and by converting the 

 compound into a simple fracture, closing the external opening 

 by a good, stiff plaster — the Burgundy or common pitch will do 

 ve^y well- A broad bandage may be applied around the body.
