as possible ; hard work and rough roads are carefully to 

 be avoided. With these precautions the animal may work 

 for a considerable time ; but an evil day must arrive, and 

 the animal will turn out utterly worthless. 



CHAPTER VIII. 



THE ANATOMICAL STRUCTURE OF THE HORSE. 



It is not our intention to go deeply into the anatomy of 

 the horse, as this would far exceed the limits of such a 

 work as the present, and indeed would not be suitable for 

 a popular treatise. We shall therefore confine ourselves 

 to such an outline of his structure as will convey a pretty 

 general idea of what is truly useful to possessors of horses 

 in general. 



We may briefly state, that the bones of the skeleton and 

 the muscles which cover them are all double, if we except 

 a very few bones which lock the two halves together ; and 

 that if an animal is divided correctly into two halves, these 

 will be found exactly similar in the number of bones and 

 the muscles with which they are covered. But this does 

 not extend to the internal organization in general, although 

 a few of its parts are also double.

Instead of giving the bare skeleton of the horse, we have 

 considered it better to exhibit an outline of the external
