My dear Hayss:

I just received your note, and am pleased at its import. We shall be looking
forward to seeing you in September. I expect to be occupied at moving to a new
house on September 1, and so would prefer if you could manage to get here after
the second. Ths following week there is to be a meeting on campus of a very large
group of biologics] acocieties (American Institute of Biological Sciences) which

you may or may not wish to avoid.
A reprint of our lysogenicity paper should be waiting for you at Lordon,
Till then,

Sincerely,

Jeahuas Lederberg
