Dear Joshua,

Thanks a lot for your comments on my Genetics paper.
Sénee this is a hasty note, with a sinister purpose, I hope
you'll forvive me if © don't discuss the points you raised
just now. A fuller letter on this will follow eventually.

Brie@ly, what this note is concerned_with is this:
A number of us Carnegie-ites ( Newcombe, Beale, Poerman and
yours truly -- Bryson too, probably, tho we haven't asked him
yet) got to talking about your material and techniques, and we
all agreed it would be verv nice to get some pointers from
you about them. We decided to ask you whether you would care
to visit Carnegie for a few days, or as long as you find necessary,
to give a course in the sex life of K - 12. There will probably
be just the five of us, and from our point of view it would be
better if you could come here, rather than having one of us see
you at Yale, and report second hand. Since Dr. Demerec is away on
vacation, and is unreachable, this is not official, but nonetheless
we have arranged to pay your eEpenses, and have made sure that
there will be a room for you, and for Esther too if she comes along.

Having no idea whether youre too busy for such a
jaunt or not, we thought we'd ask you anyhow, and hope that you're
able to come. As far as we're concerned, any time at all is
satisfactory, thexamiyxunza with the exception of July 30 and the
following few days, since Newcombe will be away then. If some
time this summer is out, we'll all still be here in the fall, tho
we hope that you can meke it some time soon.

Can you let me know the verdict as soon as possible?
Apologies for the rush, but I will write again,

With best regards to you and Esther,

Yours

Cul
