THE HORSE, ITS DISEASES. 493 



If taken in time, and treated in this way, the healing may take place 

 without deformity. 



When once the bony excrescence has established itself, no one but % 

 wilful veterinary surgeon should be entrusted with its removal. 



IX. Swellings by Pressure of the Bridle. 



These, as the designation indicates, are swellings, sometimes sores, and 

 occasionally, when of old standing, callous lumps, made by the pressure 

 or rubbing of the bridle upon that little prominence on the neck just 

 below and back of the root of the ear. If the swelling is simple and 

 recent, remove by saturating it with the camphorated corrosive sublimate 

 (No. 2) and drying in with a hot flat iron, held close without touching. 

 This must be attended to once a day, and the bridle must be kept off 

 during treatment. If there is a sore without fungous growth (proud flfesh) 

 the same treatment will be found effective. 



If the tumor is of old standing and fungous, the proud flesh must b« 

 burned away with lunar caustic. If it is old and horny, resort must be 

 had to the knife, after which the wound may be healed by a dressing of 

 simple cerate, -or of any of the unctuous oils. 



X. Sore Nose. 



The nose sometimes becomes sore from long-continued purulent dis- 

 charges, from any irritating substance introduced, but generally from 

 grazing near some irritating weed or vine. Jamestown weed will often 

 poison the noses of horses, yet the leaves, buds and pods are eaten with 

 impunity. So-called *' sneeze weed " will also irritate the nose and cause 

 it to become sore. As a rule rubbing the nose with mercurial ointment 

 in which equal parts of sulphur and lard has been intimately mixed will 

 effect a cure. Apply with a mop, if out of reach of the hand, to be 

 rubbed in as well as may be possible. 



XI, Roaring and High-blowing. 



This is when a horse emits any unnatural noise in traveling, whether he 

 simply be thick winded, or emits the peculiar noise when hard urged, or 

 the sharp sound denominated whistling and piping, similar to roaring, 

 but a more confirmed type, occasioned by a strong closing of the rima 

 glottidis. Whistlers are simply chronic or confirmed roarers, and roaring 

 precedes whistling. Both impediments to breathing are produced by 

 atrophy or wasting or degeneration of the muscles whose office it is to 

 dilate the larynx. 



Thick wind is from an inflamed and thickened condition of the smaller
