The mutant I need[?] was Y-139 (-anz, -histidone); no significant difference in no. of [ . . . ] in advance of [ . . . ] pistrate[?].
The [ . . . ] was played[?] with variations. I think that either the transforming prep was inadequate (for which we have
as yet no test[?]) or the dipirincy[?] will not be transformed. For chrissake [sic] get us a C2R. I have played with a few
roughs[?] but they wouldn't transform, transformable R must be something of a rarity. This would seem to cast even more
suspicion upon the significance of experiments with the C2S supposedly mixed population.
Re: amino acids; Sinote's[?] test w. equal cell snop[?] (K last[?]) at level of on.[?] 75 v. remid[?] a /oc , how slight
but almost imperceptible difference in form of C1. What this means I am hesitant to say. I'll settle for a C2R.
