Dear Josh--
Pardon my slowness in answering your letter. I believe that I get the idea, all right, of your evidence for the diploid strain.
Lately, I've been thinking that I should overcome my congenital reluctance to work on a confirmatory problem--and attempt to repeat your recombination stuff with your strains of E. coli and also with some B. subtilis strains of mine. I am beginning to really stack up the B. subtilis mutant strains. The only bottleneck is characterizing them. I shall have to develop a really efficient technic[sic] of "pin-pointing" a requirement on a production-line basic.

[BEGIN PAGE TWO]
So, I'd appreciate it if you send me some appropriate strains for a recombination expt and in return I shall send you the lactose-galactose bug.
Incidentally, I still plan to use L positive G negative to yield L negative G positive rxn for expts on effect of U.V. and X-ray the rate in both direction, though Zelle's Trypt positive yields Trypt negative should be a better bug. We discussed this before, I think.
I just heard Werner Maas talk on "Mech of d-serine inhibition of E.coli" at the Navy across the street and expect to eat dinner with him now and hear what he and B. Davis have been up to in N.Y.
Yours,
Bob G.
