I promised to write you about our experience with cyclorevine. Unfortunately the concentration used (150/ml) did not give
sufficient inactivation to give conclusive results. At a survival of [about] 10-4 after treatment there was 1 glucose negative
in [about] 104 colonies examined.
One other thing. The anxiety about my relationship with Men Cohn was groundless. He wrote me a very intelligent sweet letter.
Things heard third hand are rarely true. I'm so pleased that all is straight as I like him very much.
No doubt you are about to leave any minute for Stockholm. Bon Voyage and Congratulations from all of us.
