the delicate organs or exposed regions, as the case 

 may be, regardless of age, value, or breed. 



Of course, remedies and treatment are being 

 worked out to meet these individual diseases as 

 they occur. Nevertheless, the best treatment is 

 prevention. It is far better to prevent than to 

 cure; and that is the line of action especially for 

 this class. Indeed, it is far easier to understand 

 the simple laws of prevention than the complicated 

 curative processes. Especially is this true since 

 germs are known and isolated, and their rapid de- 

 struction with air, sunlight, and disinfectants 

 understood and available. 



ORIGIN OF DISEASE 



Enough has now been said to indicate that dis- 

 ease originates as a reaction between the cause of 

 it and the body. Withhold food, and starvation — 

 the disease — follows. Withhold fresh air and oxy- 

 gen, and the tissue breaks down ; disease results as 

 a reaction from the normal use of air and the de- 

 mands of the body for oxygen. Allow bacteria 

 admission to the body and settlement in the 

 tissues or organs most agreeable to each particular 

 one, and these will grow, multiply, and, unless 

 overcome by the natural resistance of the body, 

 will conquer and destroy, causing sooner or later 

 death and decay. 



Immunity Sought by Inoculation. — Many dis- 

 eases that now yield to no curative treatment are 

 being met by inoculation. By this method the body 

 is reinforced by serum injections, that disease germs 

 and infections may be warded off, or in case of at- 

 tack, be so fortified against the disease germs as to 

 destroy them or render them inactive.
