Dear Werner:

Thank you for your letter of the 14th, and the ms. It seems to show a few
small changes from the previous draft. We are expect&ng a visit from Hayes
early in September. I agree that any "conflict! ig much more in the point of
view than in the conclusions that have been reached. Rather I would prefer
to reserve any conclusions until theeevidence is more binding. However, we
are fairly certain that elimination occurs mmkx after there has been opportunity
for crossing-over, so there is no need to postulate deficient gametes as well.
But it will all come out in the wash, and the less fuss meanwhile the better.

“@ will be going to San Francisco after all. Have a good time in Burope,

and say hello to the Parisians, Stecker, Spicer, and especially Cavalli if you
seo then.

Sincerely,

Joshua Lederberg
