08 THE DISEASES OF THE HORSE. 



or animal poisons, especially those of overcrowded stables, 

 &c, are believed to be predisposing causes of glanders. 



The discharge from the nostrils caused by caries of the 

 nasal bones and the roots of the upper molar teeth (the 

 back molars), is sometimes mistaken for glanders. This 

 need not be if the following facts are noted : In glanders 

 the discharge, at first, is never fetid ; in caries it is always 

 fetid. In glanders, however, the discharge becomes very 

 offensive in the course of time. The latter fact is very 

 valuable in a diagnostic point of view. 



When described as distinct diseases, glanders is said to 

 affect the nasal membrane, farcy the skin. 



Remedy. — Dress farcy buds with mercuric iodide oint- 

 ment or stick of silver nitrate. Sodium hyposulphite ; 

 iron and copper sulphates ; arsenic internally. Liberal 

 diet; exercise desirable, except in acute cases. Isolate 

 from healthy animals ; disinfect. Treatment only pallia- 

 tive. Better slaughter. (For doses, see pages 13 to 29.) 



OSTEOPOROSIS (HARDENING), 



Consists in the excessive development of the tissues 

 which occupy the canals and cells of bones, while at the 

 same time the actual quantity of bony matter remains 

 unaltered. (Rokitansky.) From perverted nutrition the 

 bones are thus swollen and brittle. The cartilaginous 

 tissues, and even the teeth, undergo similar degeneration. 

 The disease occurs in horses, cattle, and sheep. 



Incurable. Prevention consists in furnishing food con- 

 taining a proper proportion of all the elements of nutrition. 



FLYBLOW (Magots from), 



If neglected, may result in death. Sheep suffer more 

 perhaps than horses. 



Remedy. — Turpentine; tar oil; corrosive sublimate 

 solution.
