ANTIMALARIAL MEASURES IN THE UNITED STATES 



Dr. A. Woldert, in a small pamphlet entitled 

 " Malarial Fever and its Expense to the People of 

 Texas," has calculated from an examination of ^'arious 

 official records that the loss in money caused by 

 malarial sickness upon three railway systems amounted 

 to 133,810 dollars a year ; and calculating upon the 

 same basis, viz. that one person in twelve is affected 

 with malaria in Texas, he reckons the total loss to 

 the State as 5,333,320 dollars a year. He gives these 

 figures to support the necessity for a vigorous anti- 

 malarial campaign. 



Dr. A. H. Doty of New York has rendered excel- 

 lent service by directing attention to the extermination 

 of tlie mosquito on the ^Vtlantic side of America, 

 where already nuich lias been done by the American 

 Mosquito Extermination Society of Xew York.
