Vera Cruz, Mexico, April 12, 1903.

To the Editor:  —In The Journal, April 4, appears an article by Dr. J. Stebbins King on "The. Mosquito as a Carrier of Disease." In this article Dr. King makes the following statements:

  1. ... Hundreds of non-immunes are bitten every year by infected culex mosquitoes where yellow fever exists as an epidemic and do not take the disease."

  2. ... Non-immunes can be exposed for days and months to yellow fever, and that, too, in the presence of infected culex mosquitoes, and not take the disease....

  3. The Doctor does not so state, but implies, that the mosquito is not the only means of transmitting yellow fever.

  4. The writer,... can most positively vouch for the truth of every statement here made [in his article].
