CHAPTER XXXIV 



MICROBE OF THE COMMON COLD 



COLDS are " catching " a popular impression. 

 In this matter people are coming to the front, 

 they see, think, conclude. 



Why should they not? Before their eyes, one 

 member having a cold, that cold usually goes 

 through the family. One member catches it from 

 another. 



Before their eyes the same cold frequently be- 

 comes epidemic the whole community catches it. 



Before their eyes nurses in tuberculosis sanitor- 

 iums dread to have friends, having colds, visit their 

 patients. The patients are almost sure to take 

 the colds. 



Before their eyes Arctic explorers, while in the 

 arctic regions, have no colds, no people there 

 from whom to take the cold. As soon as they re- 

 turn to civilization, the explorers have bad colds, 

 taking them from the people with whom they 

 mingle.
