 that are most conducive to health. 



Effect of Exercise on the System.— The various 

 tissues of the body have but a limited time for existence, 

 which period is directly influenced by the amount of 

 exercise taken by the animal. Apart from the necessity 

 there is for exercise to develop muscle, to reduce fat, and 

 to maintain health, experience also teaches us that tissue 

 which is formed under conditions of rapid waste and 

 repair, is stronger and of better quality than that subjected 

 to more gradual change; and anatomical investigation 

 proves that the former, from being more vascular, is 

 redder and healthier-looking than the latter. Hence, to 

 improve the qxiality of the muscular and nervous tissues, 

 we should give as much exercise as is compatible with 

 the individual capabilities of the animal trained. 



Exercise purifies the blood by quickening the action 

 of the lungs, which supply oxygen to the vital fluid for 

 the breaking up of effete matters contained in it. By 

 quickening the circulation, it stimulates the processes of 

 nutrition for the building up of new tissue, and, of excre- 

 tion, for the removal of effete and deleterious substances. 

 It also strengthens the action of the heart and lungs. 



Nature of Exercise. — We may conclude that this 

 should gradually conform to that of the race for which the 

 animal is being trained, so that, speaking generally, only 

 the muscles which are particularly used in galloping may 

 be specially developed; for, were other muscles also 

 called into abnormal play, their extra nutrition would but 

 tend to deprive the muscles used in galloping of material 

 for repair, and would add unnecessary weight to be
