Dear Dr. Lederberg:

Thank you very much for the culture ( W-3231) of which I return
the acknowledgement copy . Before we open the culture we would like
to know if it is the bacterial of the L-ephase of E.coli. Actually we
would like to have both, the stable L-phase and the original bacterial
strain. We would be most graceful to hear from you again about the ship-
ped culture and would appreciate to get also the missing phase, depending

on what W-3251 is. Thank you very much indeed for your helpfulness,

Very sincerely yours,

? U? Pie,
