The cards of type-printed text, in parallel columns for convenience of study, are self-explanatory. Such an arrangement has from the first seemed to me indispensable for proper study and comparison. The paging of the de Rosny editions I have retained, except to change the practically blank page 1 to be page 25, since to number this as 1 is confusing. For the divisions and the numbering of the glyphs I have made my own arrangement. It is possible that section _b_ on pages 2 to 11 should only go to the bottom line of the central figure, leaving section _d_ to read clear across the page, and another section to be made to the left of the nearly erased figures at the bottom; but the chances as shown by the lining and arrangement of the columns seemed to favor it as I have given it. Only final decipherment can decide definitely. FOOTNOTES: [7-*] In _Archives paléographiques de l’Orient et de l’Amérique_, atlas, t. I, pl. 117-142. [8-*] In his _Commentar zur Pariser Mayahandschrift_, Danzig, 1903, Dr. Förstemann does not know of the existence of this edition. [9-*] _Codex Perez_: Maya-Tzental. Redrawn and Slightly Restored, and with the Coloring as it originally stood, so far as possible, given on the basis of a new and minute examination of the Codex itself. Mounted in the form of the Original. Accompanied by a Reproduction of the 1864 Photographs; also by the entire Text of the Glyphs, unemended but with some restorations, Printed from Type, and arranged in Parallel Columns for convenience of study and comparison. Drawn and edited by William E. Gates. (_Privately printed._) Point Loma, 1909. THE COLORS The colors of the Codex afforded a number of questions for solution, some of which I have cleared up and embodied in the plates; a few are I believe insoluble. I have also been able to add a few wholly new points, not indicated by any of the preceding editions. Being unable to make a personal examination of the original, I prepared from my enlarged black drawings, above mentioned, another full set including the figures and all glyphs or other parts showing any suggestions of color. Upon these I prepared a list of nearly 200 questions covering every detail, together with certain general specifications, and had the whole made the subject of a careful and exhaustive comparison with the original at the Bibliothèque Nationale. This report, when duly returned with the various details set out, with the various colors shown in their exact tints by water-colors, and with a special analysis of the question of the fading of the colors, was again checked and verified by the evidence of the three editions. In doubtful questions arising from faded colors, I have sought to show the condition of the original as it exists today. In the solid red backgrounds and other places I have aimed to show as far as possible what the Codex looked like when fresh.
