Mosquitoes and Malaria 119 



In the same year two English physicians, Sam- 

 bon and Low, went to Italy where they built a 

 cabin in one of the marshes noted as being a 

 malaria pest-hole. The house was thoroughly 

 screened so that no mosquitoes could enter, but the 

 windows were always open so as to admit the air 

 freely day and night. Here they lived for three 

 months, out of doors as much as they pleased dur- 

 ing the day but inside where they were protected 

 from the mosquitoes at night. No quinine was 

 used and no fever developed, although all about 

 them other people were having the fever as usual. 



Another English physician who had not been 

 in malarial regions allowed himself to be bitten by 

 infected mosquitoes sent from a malarial locality. 

 In due time he developed the fever. Many other 

 experiments made in various places might be cited. 

 The results have all been practically the same. To- 

 day the soldiers of many civilized nations are re- 

 quired to protect themselves from mosquitoes be- 

 cause it has been found that it pays. Disease has 

 always been a worse terror than bullets in any war, 

 and we are fast learning that the great loss from 

 diseases heretofore considered unavoidable may be 

 very largely eliminated by proper sanitary arrange- 

 ments and protection from noxious insects.
