Dear Dr. Lederberg:

Thank you so much for sending us the two clippings from your columns
with your note of March 31. We are indeed pleased to have such a
constructive article on the Aedes aegypti Eradication Program as you
have written. We wish there were more columnists with your broad
understanding of the problems involved in Aedes aegypti, vaccinations,
quarantine, and eradication programs.

Sincerely yours, >
