Prohletn 247 : How to discover tlie presence of adenoids. 



Method. — A good medical authority has given the following 

 symptoms as indicating the presence of adenoids, growths in the 

 nose and throat which prevent a sufficient air supply from reaching 

 the tissues of the body : 



1. Inability to breathe through the nose. 



2. A chronically running nose, accompanied by frequent nose- 

 bleeds and a cough to clear the throat. 



3. Stuffy speech and delayed learning to talk. ' Common ' is 

 pronounced ' cobbed ' ; ' nose/ ' doze ' ; and ' song/ ' sogg.' 



4. A narrow upper jaw and irregular crowding of the teeth. 



5. Deafness. 



6. Nervousness. 



7. Inflamed eyes. 



Observations. — Observe members of your own family. 

 Conclusion. — 1. Do any of the family appear to have adenoids ? 

 What makes you believe this? 



2. What ought people suffering with adenoids to do? 



Problem 248 : To find some ways of preventing the spread of 

 disease. 



Note. — Remembering that disease germs must come from the bodies of those 

 who are sick and that such germs are spread usually by means of material from the 

 mouth, food tube, or other openings where germs could escape, our problem be- 

 comes threefold. The three parts of the main problem are : first, the destruction of 

 such germs as escape from the bodies of the sick ; second, the prevention of such 

 germs as escape from entering the body of well people ; and third, the problem of 

 how to make the body safe or immune from the attacks of such germs as do get into 

 the body of a well person. 



a. How to kill Germs that escape from the Bodies of those who 



are Sick 



Method and Observations. — Using your Civic Biology and such 

 other books of reference as you have access to, answer the follow- 

 ing questions: 



Take some specific disease, as typhoid fever, tuberculosis, or 

 diphtheria. From what part of the body do the disease-causing 

 germs escape ?
