Dear Joshua, I am enclosing a manuscript (finally cleared by the army as not being too much of a security risk) and I would very much appreciate your comments and suggestions before anything further is done with it. Also enclosed: Photostat of paper by Frisby and Hollis letter from Stuyvesant H.S. (I have no idea how they got my address) receipt of acknowledgement of cultures [...] At the moment we have been finding that Vi cultures are quite refractory to PLT-22; there also appears to be some difficulty in preparing high-titered k' (determinant) phage. Major Morse (Larry Morse's brother) was by for a short visit and sends his regards to Larry. Regards to all, Lou L.S.Baron P.S. I assume the cultures you picked up were typical.
