AS Wilkins 3/10/94 Memoris [sic] in Bioessays. I appreciate the opportunities offered. But I'm already committed beyond capacity. For Hayes, the most appropriate would be his erstwhile collaborators in Paris -- Elie Wollman or Francois Jacob. For B. Davis -- I really wish I could. But I'd pass the baton to: Gerald Weissman -- NYU Werner Maas -- " Boris Magasanik -- MIT Bernie Fields -- Harvard Dulbecco, Eisen, or Ginsberg -- coauthors of his text book. Sincerely Joshua Lederberg 3/10/94 [written in right margin, B Davis]
