condition for these little germs to gain a foothold. The 



air in temperate climates always contains large numbers 



of these germs, which we inhale freely every day, but 



which are harmless as long as the 



body does not offer them a favorable 



soil in which to grow and multiply. 

 The most dreaded and fatal of 



all diseases known is consumption. 



From ten to twenty per cent of all 



deaths in temperate regions are due 



to this terrible disease of the lungs. 



One person in every seven falls a 



victim to the "great white plague." 



Massachusetts, during a period of twenty years, statis- 

 tics show that four- 

 Evstachiantube teen per cent of all 

 deaths reported were 

 due to consumption, 

 and that the mortality 

 was greatest between 

 the ages of twenty 

 and thirty years. The 

 germs reach the lungs 

 and there multiply so 

 rapidly that the parts 

 affected soon become 

 useless. 

 Adenoid growths occur very often in the back part of 



the nose and in the pharynx of young, rapidly growing 



children. They obstruct the nasal passages and make
