[Design of Marci Letter]

[Linda]

It sounds like he is suggesting that physical tests could possibly be done that could prove the hypothesis that Marci's letter was never a letter, but a flyleaf, bound under the inner cover, explaining why the letter was not in the correspondence lists, and also removes any ambiguity about whether this is the book referred to in the letter, by establishing it as part of the physical provenance.

I like it, can someone go look?
