CONDITION. 247 



extremely useful. The stable should be well 

 ventilated, but not cold ; regular exercise \\ ill 

 also be verv beneficial, and should never be 

 omitted. It should be understood, however, that, 

 although exercise tends to promote strength^ 

 if carried beyond the cininial's power, it be- 

 comes a cause of debility : it is highly neces- 

 sary, therefore, when a horse is in a state of 

 weakness, to take care that his exercise is but 

 moderate. 



Worms in the stomach and bowels are a 

 frequent cause of leanness and debility in 

 horses; and while they exist, every exertion to 

 promote condition will be ineffectual. (See 

 Worms.) A defect in the organs of respiration 

 will also produce weakness and emaciation. 



If the blood be not duly supplied with that 

 vivifying principle, which is derived from the 

 air by breathing, a greater or less degree of 

 debility must be the consequence; hence a 

 want of tone is always observable jn the sto- 

 mach and bowels of broken winded horses, as 

 well as a deficiency in the muscular power in 

 o-eneral. The same evils will result from 

 keeping a horse in too close a stable, where 

 the air does not contain the usual proportion o? 

 this principle.
