uncontrollable, very frequently indicates whooping-cough. A croupy 

 cough, that is, a cough which is harsh and ringing, may indicate the 

 disease diphtheria. A painful cough may indicate disease of the lungs, 

 especially pleurisy or pneumonia. A long-continued cough may mean 

 tuberculosis of the lungs. 



Vomiting. Vomiting usually, of course, merely means some di- 

 gestive upset. It may, however, be the initial symptom of many of 

 the acute diseases, and is therefore of considerable importance. 



Frequent Requests to go out. Teachers are too much inclined to 

 think that frequent requests to go out merely indicate restlessness or 

 perversity. They often, however, indicate trouble of some sort, which 

 may be in the bowels, kidneys or bladder; therefore, they should always 

 be reported to the physician. 



THE TEETH 



Unclean mouths promote the growth of disease germs, and cavities 

 in the teeth are centers of infection. Pus from diseased teeth seriously 

 interferes with digestion and poisons the system. It causes a lowering 

 of vitality and renders mental effort difficult. Diseased teeth, tempo- 

 rary as well as permanent, are frequently the cause of abscesses, and 

 should be carefully watched and treated. 



Irregularities of the teeth, especially those which make it impossible 

 to close the teeth properly, lead to faulty digestion, to mouth-breathing, 

 and to other diseases and evils which an insufficient supply of oxygen 

 produces. 



The first permanent molars are perhaps the most important teeth 

 in the mouth, and are the most frequently neglected, because they are 

 so often mistaken for temporary teeth. (It should be remembered 

 that there are twenty temporary teeth, ten in each jaw, and that the 

 teeth that come at about the sixth year immediately behind each last 

 temporary tooth four in all are the first permanent molars.) 



The teacher should be on the lookout for pain or swelling in the face. 

 When the child keeps the mouth constantly open, an examination of 

 the teeth should be made. When symptoms of indigestion occur, or 

 physical weakness or mental dullness is observed, the teeth should be 

 inspected. It should be remembered that disease of the ears, disturb- 

 ances of vision and swelling of the glands of the neck may be caused 

 by diseased teeth. 



It should be known that decay of the teeth is caused primarily by 

 the fermentation of starchy foods and sugars, and that the greatest 

 factor in preventing dental caries is the removal of food particles by
