 bilities to which horses are at present lia- 

 ble are traceable to deficient oxidation of 

 the tissues, caused by withholding the 

 supply of fresh air which their nature re-

When a horse is violently exercised, all 

 the tissue changes are accelerated. The 

 heart beats quicker. The breathing is 

 hurried. Why ? Because there is more 

 waste tissue to be disposed of The blood 

 rushes to the lungs for more oxygen, and 

 the lungs hurry the breathing to meet the 

 demand.
