 through the early discovery of disease. 



The Nose and Throat. It is generally recognized that the 

 germs of many diseases, such as tuberculosis, pneumonia, colds, 

 measles, and scarlet fever, gain entrance to the body through the 

 nose and throat. For this reason it is important that these organs 

 be properly cared for. Nature has provided them with two main 

 defenses against germs, tiny hairs in the lining of the nasal 

 passages and mucous secretions in both nose and throat to catch 

 the germs and hold them. These defenses are, however, not 

 always effective, and it is therefore wise to spray both nose and 

 throat with an antiseptic solution once or twice a day when such 

 diseases are prevalent. 



Tonsils. Healthy tonsils are harmless, but when diseased 

 they harbor germs which lead to sickness. Diseased tonsils are 

 a source of danger and should be removed.
