enclosed please find a manuscript, dealing with the material of the seminar [ . . . ] in your Department this X-mas. Since
at that time some points were not clear, because of the lack of available experiments, I though you may be interested to see
this work in a more complete form[?]. Would you be so kind and also give this text to Paul Berg, to whom I am particularly
indebted, because of his keen interest in some biochemical problems related to our discourse.
Let me thank you again for the opportunity to visit you and for our intellectual encounter.
With warm regards
P.S. the MS. is presented to the Natl. Acad. in April. Could you please have the text referred[?] to me after you and Paul
are finished with it.
