Fed alive to mosquitoes. Washington, D.C., April 24. One of the unsung heroes of the government service is Carroll Smith, research expert in equine fever in the Bureau of Entomology, Department of Agriculture, who since 1927 has allowed himself to be fed alive to a horde of mosquitoes. After a feeding on his arm, Mr. Smith lets the mosquitoes bite an infected guinea pig, after which they are permitted to bite an uninfected one. In this way he ascertains the extent to which mosquitoes transmit disease among horses and cattle. For his purpose the mosquitoes must be pure, says Mr. Smith in explanation of why he lets the insects feed on him instead of taking their bites out of any old animal, 4/24/1937
