During her 1954 visit to the United States, Franklin visited many virus researchers who would subsequently collaborate with
her on projects involving virus structures. Barry Commoner sent her samples of a protein he called B8, to compare with the
x-ray diffraction studies of TMV protein. They subsequently published several articles together. In this letter, she acknowledged
the safe receipt of the samples, and some recent news from another colleague, Alexander Rich, on TMV structure.

Thank you very much for your letter and for the B8, which has arrived safely. It should be enough to give me several specimens
provided I don't in any way mess it up while concentrating it. I shall have to evaporate it to a very small volume to
obtain a gel sufficiently concentrated to work with. I shall let you know, of course, as soon as I see how it goes.
By the same post I had a typescript from Alex Rich (who previously worked with Watson, and is now in Washington) about some
X-ray work on Neumark's RNA-free TMV protein. They get photographs which resemble normal TMV but are not good enough
for detailed measurements. However, they do find evidence that the RNA is at the centre. If we can get improved photographs,
comparable with those of TMV it will be worth making detailed measurements in the hope of finding out something about the
structure of the RNA.
My Nature article has just appeared, but, as I imagine it may be several weeks before it reaches you, I enclose a proof copy
of the diagram you ask for.
