is very little doubt that these structures are correct — although the derivation is
not straightforward, there is a lot of evidence in support of them.
We shall have a short letter in Nature and a paper
in the Proceedings of the National Academy of Sciences next
month on the structure of the nucleic acids. We think that
it is likely that all nucleic acids have the same structure
and that it is the one that we have discovered, which in-
volves three polynucleotide chains tightly twisted about one
Everything is going along well here. I am looking forward to a brief stay in England
in April, probably about 15 April, just after the Solvay Congress in Brussels.

We all send our best regards to you and your family.
