254 BACTERIA, YEASTS, AND MOLDS 



Do not wet the fingers in the mouth for the purpose 

 of turning the leaves of books, especially library books, 

 inasmuch as book leaves are sometimes the lurking places 

 of disease bacteria. 



Do not put pencils in the mouth. 



Do not put money in the mouth. This is extremely 

 important, because money is liable to come in contact 

 with all sorts of people and to become contaminated with 

 many kinds of disease bacteria. 



Do not put into the mouth anything that another per- 

 son has had in his mouth. This refers to gum, apple 

 cores, candy, whistles, bean blowers, drinking cups, etc. 



Turn the face aside from others when coughing. This 

 will sometimes prevent contagion passing from one per- 

 son to another, inasmuch as the breath in coughing 

 distributes disease germs. 



Be always particular about personal cleanliness, fre- 

 quently washing the face and hands.
