Dear Seymour:

Thank you for your note of July 29. I'd heard about “allter Rosen from
Nancy Ziebur and from Skoog. I hope we can arrange for him to further these
studies, aftar he gets here.

In one of your papers you mantion laboratory "glass"=ware made of polyethene
which can be sterilized dn the autoclave. I would be especiully interested in
centrifuge bottles and other conte ners of such a stuff. Can you tell me who
makes and sells it?

We are nlanning to vacation in Fastern Quebec, and may very well drive through
Halifax, as you suggested.

Sincerely,

Joshua Lederberg
