DISSEMINATION OF BODY-LOUSE 43 



Body-lice are found on man all over the world, 

 and there is probably no tribe free from them. 

 They are, however, less prevalent in tropical than 

 in temperate and cold climates, and in temperate 

 regions are less numerous in summer than in 

 winter. This is in correlation with the different 

 habits of people in the winter. Then under- 

 clothing is more likely to be of wool than of cotton, 

 and lice prefer the former material. It is also 

 the custom with many people in this country, 

 for some reason that is difficult to understand, 

 to change woollen garments less frequently than 

 cotton ones. Among certain classes in winter 

 the day clothing is also worn at night. People 

 also at this time keep more indoors and crowd 

 together over stoves. All these habits are in 

 favour of the spread and increase of lice, and 

 there is no creature in creation more ready to 

 seize Time by the forelock.
