Dear Professor von Neumann:

I imagine your official duties do kot leave you mich time to sustain
your academic interests, but perhaps you will recall our earlier brief
correspomence on the subject of "self-reproduction".

to bs published in a Growth Society symposium by the Princeton University
Presa. I am looking forward to recaivgting any comment you my wish to
make .

Yours sincerely,
