Dear Doctor Lederberg,

May I once again impose on your good
nature. Our library here has tried unsuccessfully
to find Dr. V. Sertic's address for me in order
that I could write to him. Do you have in your
laboratory Sertic and Boulgakov's H phages VIII-113
and one other which is specific for the "d" antigen?
I would greatly appreciate it if you would be good
enough to let me have these, along with any pertinent
information on their propagation.

Thanking you for your kindness, I remain,

 

Yours sincerely,

batt Suing

Bacteriologist,
Enteric Laboratory.
