This is to remind you that, as soon as you get halfway settled, Henry Vogel and I would appreciate your mailing us the con- jugation print and also a print of protoplasts and their proliferation (from the forthcoming J. Bact. paper). I am planning to be in Madison on December 4 and 5, on invitation of Joe Wilson, and I am hoping that this will also provide an opportunity to see Esther and you. With very best regards, Sincerely, CSW) Werner Braun WB:DP
