Diseases of the air passages. We are probably more 

 aware of diseases of the air passages than almost any other 

 part of the body. Nearly everybody has a cold at one 

 time or another, and we have all heard of and perhaps 

 suffered from ravages of influenza and pneumonia. Other 

 diseases which unfortunately attack the air passages are 

 diphtheria, tonsillitis, laryngitis, pharyngitis, bronchitis, 



catarrh, croup, and 

 whooping cough. 



Adenoids and tonsils. 

 Tonsils often make 

 much trouble for us. 

 Germs lodge and grow 

 in them and cause many 

 diseases. Infected ton- 

 sils should be removed. 

 Polyps are soft jellylike 

 growths in the nose 

 which cause stuffiness, 

 difficulty in breathing, 

 and thickness of voice 

 in children. If present, 

 they should be removed 

 by a physician, as the 

 loss of the sense of smell, as well as much discomfort, may fol- 

 low. Adenoids are almost always accompanied by breathing 

 through the mouth, snoring at night, and general listlessness 

 and indifference to work and play. Adenoids grow in the 

 back part of the nose, and shut off the air supply through this 

 organ. They should be treated, or removed if very large. 



Artificial respiration. Accidents which shut off the 

 supply of oxygen, are drowning, suffocation from gas,
