Dear Dr, Taubeneck:

I shoulc tave acknowledged your letter of March 12 long ago and I
offer my apologies.

The glass matrices did arrive, but I fear you were too optimistic
about the delicacy of the intermtioml postal service and they were
badly smashed, However, I could retrieve some of the marked areas of
glass and these suffice to demonstrate the utility of your technique,
I hope you will keep me in touch with further technical developments,
Can you give me the commercial description of the matrices so I can
get a further supply through trade chamels?

We have not done anything further with L forms for the past

several months, owing to interest in other research, but we may return
to some aspects soon,

I will be a co-chairman at Stockholm (with Ismenecki) of the
sections on microbial genetics, and hope to be able to see you there,

Yours sincerdly,

Joshua Lederberg
Professor of Nedical Cenetics
