Dear Josh:

Ag | mentioned to you at Boston,
we should like very much to heve you spesk at
a Genetics-Cytology seminar at Columbia on
Tuesday, February 4, at 5 Pm (tea at 4:36).
This is somewhat earlier than the date | had
orignally scheduled, but | hope thet wontt
inconvenience you any. (Vobzhandky says we can
pay your train fere).

Naturally, what we want to hear
about is the recor\nation story in E. coli. |
think it is only tair to say that most graduate
students (for whom the seminars are designed)
have only the vaguest Idea of the work, the logical
structure of the arguement,nature of proofs, etc,
since nothing has been published on it as yet.
Therefore it seems important to me that you present
the story right from the beginning. | mention this
cnly because you may not realize how tew people
areound here have more than rudimentary awareness
of the work.

Incidentally, 4 glanced brietly at
the manuscript which Ryan had a couple months ago
of yours. Vo you have an extra carbon copy of it
lying around which you could send mebefore you
come down? There are a number of points | want to
get quite straight and then discuss with you,

Sincepaly,
Vv | Foca

Note: Please send me the title of your talk for
