Dear Josh:

Thank you for your letter of November 2h and for the
mailing list. I will send the list to Stanford acccrding to your
instructions.

I have received a few strains from Esther (I guess)
and I hope to test them as soon as I will be back in Chile. I am
still missing the wild type and the constitutive eryptic, which
Monod calls W13011.

Somebody at Harvard tested the ML35, a constitutive
eryptie, and found essentially what I found before, that is a
"cryptieity faetor" ef 160. Therefore ML is not better in this respect,
than KL2, If one considers that a normal constitutive can have a

factor as high as 120 it seems necessary to look more carefully into
the problem,

With regard to my itinerary, it is very simple: I will
stay here until the 17th of this month and theg I will return to
Santiago. Probably I will be back in Albany at the end of May.

Best luck to Egther and you in your trip,

yours,
