Jim Enterline says: "The "two-pronged attempt to authenticate" are your words, not mine. All I'm trying to do just yet is shoot a hole in the claim that it has been dis-authenticated.... for 32 years I have been trying to get you or someone else to perform this experiment, which you yourself just said is critical."

I did not just say that? It was 32 years ago, Jim! I said then it was a two-pronged attempt, and it was. The experiment was critical to your scheme to de-dis-authenticate = authenticate?... the map. You are playing with words using semantics.

What shoots holes, just then and just now, in your "just yet" scenario?

(1) the anatase has not been found on the parchment. It occurs primarily in the underlying yellow-brown line not in the overlying carbon black line. I said this in my review 32 years ago and again a few days ago. (2) the carbon ink result plays directly into the scenario you suggested, with the originator quickly retracing his failed gallotannate ink with carbon ink. The scribe quickly retraced the entire map and text... almost perfectly? (3) your experiment (as I wrote earlier) did not (and does not) follow what you must require: "the recommended procedures of the day".


PS to Jim (and anyone else): Any idea why the Davis group never found, not even once, any of ...

(a) Mrs. Olin's "precipitate"
(b) the Abrahamson/McCulloch clay-anatase
(c) Your transferred anatase or
(d) Cahill's fortuitous paint flakes from a library ceiling...

...after studying 159 samples by PIXE? Didn't find even one place? Not even by accident? Missed them all? Brown and Clark (supporting McCrone) found them without difficulty and found one even where the Davis group had already been. How is that possible?
