have a contrary effect, yet I am satisfied that this is coun- 

 teracted by an opposing force, which I cannot explain, 

 rendering the arteries and veins less liable to engorgement 

 than when the circulating fluid had properties which made 

 it more difficult to propel through them. From the relief 

 afforded by copious and repeated sweatings, we might 

 infer, that the abstraction of the fatty globules in the 

 blood was the means of lessening the labor of the heart, 

 which is of the greatest importance when the blood is sent 

 bounding along more than twice as fast as when the ani- 

 mal is at rest. The theory that the pulsation keeps time 

 to the step, is, I believe, correct when the action is much 

 hurried. Hence, when a horse is making a fraction more 

 than two bounds in a second, the work of the heart is 

 greatly increased, and the labor of that vital force-pump 

 would be much lessened by the blood being easier to urge 

 through the tubing of the veins, as fast as the accelerated 

 pace required that it should be. 



It will readily be seen that nearly all the inside fat will 

 have to be got away before the respirating organs are 

 capable of performing their functions in a manner that 

 will endure fast work. The heart is also facilitated in its 

 operations by the removal, and the diaphragm and abdo- 

 minal muscles can act with far greater force, the whole 

 internal economy is in a manner changed, the muscles of 

 the stomach are strengthened, and digestion is better and 

 more rapid. The gastric juices are more intimately blend- 

 ed with the contents of the stomach, and the waste for 

 the bowels to carry off is less acrid and easier expelled. 

 ^Ye will also find that the same process will get rid of the 

 external fat, and while the load is lightened for the horse 

 to carry, and the muscular system is brought to a higher 

 state of vigor, it also assists in the expansion of the 

 chest. The intercostal muscles or the muscles between the 

 ribs have a good deal to do with respiration, and the reduc-
