Just a note to say that for those who would like to access the files (which are IMAGES, not text), and can't read the TIF format, I have converted the images into GIF, and posted them at http://www.math.upenn.edu/~jtu/davis-gif/ These files will probably be removed within a few weeks, but the TIF files will remain on the French site http://sesame.mathp6.jussieu.fr/~tu/davis
