This folder contains an offprint of a published article: Cahill, T.A., B.H. Kusko, R.A. Eldred, and R.N. Schwab. "Compositional Comparison of the Mark Hoffman 'Oath of a Freeman' and the 'Whole Booke of Psalmes'. _The Judgment of Experts: Essays and Documents about the Investigation of the Forging of The Oath of a Freeman." Edited by J. Gilreath. American Antiquarian Society, 1991. Pages 75-96. ; The items in this folder are part of the Thomas A. Cahill Papers--Crocker Historical and Archaeological Project, 1981-2009. They are from Series 1: Thomas A. Cahill Research Papers, 1981-1994. This series consists of various research papers and published articles based upon Dr. Cahill's research using Particle Induced X-ray Emission (PIXE) techniques in analyzing inks and papers. ; Compositional Comparison of the Mark Hoffman "oath of a Freeman" and the ~ole Book of Psalms." T.A. Cahill, B.H. Kusko, R.A. Eldred, and R.H. Schwab Crocker Historical and Archeological Projects (CHAPS), University of California, Davis 95616 The Mark Hoffmann "Oath of a Freeman" and the "Whole Book of Psalms" were analyzed by the external proton milliprobe at the Crocker Nuclear Laboratory, University of California, Davis for elemental constituents of the paper and ink. These analyses were supported by Mr. Justin Schillet of the Schiller-Wapner Galaries, New York, with the collaboration of E. Dunlap of the Rosenbach Library, Philadelphia, who supplied the "Whole Book of Psalms". The purpose of these analyses was to compare the documents in order to bring compositional data to bear on the authenticity of the "oath". In this article, we will give a little background to the analyses, reproduce the original report in its entirety, and then comment on the results with knowledge of events. Proton Milliprobe Techniques The proton milliprobe technique at Davis is a refinement of the technique of Proton Induced X-ray Emission (PIXE) designed to generate quantitative composition data on fragile objects without any harm. The 4.5 MeV proton beam for the ...
