Dear Dr. Lederberg:

We have your request of December 11 for a culture of Micrococcus
eryophilus and will be very pleased to send you one. Naturally
a few days will elapse before we can get a transfer from our
dehydrated stock culture but we hope to mail you a subculture
before the end of this week.

This organism was also deposited with the A.T.C.C. in 1951

and there is a possibility that theirs may be closer to the
published description after this lapse of time. You will find

it necessary to incubate this organism at temperatures below 30°C.
and protect it from high temperatures during the summer.

Very truly yours,

Milllm Zafhl
