T-ff.E S PEE AD OF INFANTILE 

 PARALYSIS 



In an article by Mr. Charles T. 

 Brues, of the Bussey Institution of 

 Harvard University, on insects as 

 agents in the spread of disease, pub- 

 lished in the last issue of the Monthly, 

 a footnote was added to the effect that 

 since the article had been written ex- 

 periments with monkeys by the author 

 and Dr. Eosenau showed that infantile 

 paralysis, poliomyelitis, can be trans- 



mitted from one monkey to another by 

 the stable fly, Stomoxys calcitrans. A 

 brief account of the experiments was 

 presented before the International Con- 

 gress on Hygiene and Demography in 

 September and has been printed in the 

 Monthly Bulletin of the Massachusetts 

 State Board of Health. 



Monkeys were infected by injecting 

 virus from man into the central nervous 

 system, and large numbers of stable 

 flies were permitted to bite them.
