Or. Tracy Sonneborn of Indlena University has Just written me concerning
his mosination of H. J. Muller for the National Neda! of Science, which
i an most happy to endorse. te tells me that he had already quoted me
in extenso In support of his own momination of Dr. Muller, and it aay
therefore be unnecessary for me to edd any additional language. There
can be no question. of the correspondence of Muller's career to the
criter!s for candidacy that your letter enunc!l ated.

Yours sincerely,

Joshua Lederberg
Professor of Genetics
