Another point on page 17 is to be noted. In the top section, first column, are five blue 3’s. Some of these blue dots, as shown in the 1887 edition and in my water-colors, have faded to the same light brown seen elsewhere. The brown and the blue 5 in the second column of this page, middle division, as just mentioned, have also an identical chromatic value in the photographs. My whole conclusion therefore, so far as I can formulate one, is that in these columns we have: Red, black, and blue-green numerals, as shown. Some of the blue numerals seem to have been _outlined_ with black, of which traces still appear on the original, are seen in the photographs, and indicated in the present color plates. Several instances where the Codex has been rubbed so as to leave only the outlines of original black numerals. These are now gray in the original, and I have left them as black outlines, touched in with gray. Finally, a number of pale brown numerals which are either faded blue-greens, or else indicate a fourth color in the original. Which of these alternatives is the true one, I cannot say. * * * * * The original Codex is still in practically as good condition as when the three editions were taken from it. The material of which it is made is a maguey paper of grayish tinge, and not a yellowish brown as would be inferred from the 1887 edition. This is noteworthy, as the wearing away of the coating with which the paper was surfaced for the writing, does not leave a brownish place which, as in the 1887 edition, might be mistaken for traces of applied color. This coating is indeed better preserved in places than is shown by the 1887 edition; thus the headdress at the extreme left of page 20, just to the right of the restored 8 Ezanab on the present color plates, is shown with the coating all erased and the black writing as if left on the ground-paper--which is incorrect.
