have only shown 12 instead of 13 day-signs in each column, but a measurement of the space above and below shows that the missing four are to be placed at the top and not at the bottom. These two pages therefore have application in some way to 52 solar years, beginning with 1 Lamat and ending with 13 Akbal (Votan).

These “year-bearers” are those of the Tzental instead of the Yucatecan system, as described by Landa, and on these two pages rests, so far as regards known subject-matter, the assignment of the Codex Perez to the Palenque rather than to the northern Maya district. It is thus to be considered with the Inscriptions of that region, and with the Dresden Codex.28-* And in accord with what is known of the state of the different parts of the country at the time of the Conquest, and of the history of the break-up and extinction of the Maya empire, it must be assigned the greater antiquity on that account.

It is probable that pages 19 and 20 had no text passages.

Pages 21 and 22 again, judging from the coloring and the arrangement, seem to form a pair. Each had on the upper part probably five rows of glyphs, some 70 in all, of which only 10 or 12 are at all recognizable. Contrary to all the pages hitherto discussed, it may be that these glyphs are to be read from right to left. The faces in these all look to the right, and the customary prefixes are all on the right. In classifying these glyphs, therefore, they must be all reversed.

The greater part of page 21 is framed in and divided up by green bands, evidently for water, two branches of which, after crossing a constellation band near the bottom, end one in falling torrents, the other in a circle surrounding a kin-sign, , the sun, and itself surrounded by four dragon’s heads, all figured in the midst of the torrents. Below this symbol is the open mouth of a dragon, towards which is looking and pointing a black-faced figure, of the god D, the Ancient of Days, described by Schellhas as the moon and night god. To the left of the torrents is a figure, nearly erased, but with the wristlets characteristic of the god of death, and holding in the hand a torch. The glyph occurs written in the torrents, at the left side.

The green bands divide the middle of the page into six compartments containing, so far as not totally erased, 65 day-signs, in columns of five. All my efforts to relate these signs either to each other or to any other series in the codices, have so far been fruitless. The upper seven columns have each a black numeral beneath, running from right to left, 1 2 3 3 5 6 and the dot of another 6.

Each of the columns of five day-signs forms a closed circuit returning into itself. In the upper row the 1st and 6th columns show successive days 8 apart in order; columns 2, 3, 4, 5 and 7 are 16 apart in order. The 1st in the lower row is at intervals of 8, the 2nd and 5th at intervals of 16. The 3rd column is, with the 4th, an exception, the intervals being successively 8, 4, 4, 8, 16. That this is probably not a scribal error is shown by the fact that the same series, though beginning with different days, occurs in both columns. The 6th and possible 7th columns of the lower part are indeterminable.

We thus have three rounds of 5 times 8, or 40 days; seven rounds of 5 times 16, or 80 days; two irregular rounds of 40 days. These are not such columns as could form the beginning of a series of tonalamatl fifths, in which the successive days come 12 apart. So that this section must be left unexplained.29-*

At the right of page 21 begins a solid red background which probably extended right across page 22. Two standing spotted green figures appear on page 21; seven seated figures, one green spotted, on page 22.

Page 22 is crossed by a winding dragon whose body is covered by the “constellation band.” A narrow green band also winds across the page, inclosing two of the upper figures. Below the dragon and this green band are seen, seated above the open mouths of two erect dragons, two figures in conversation, each bearing various insignia of the death god. A very curious cartouche outline, partly erased, at the lower right, incloses what seems to be 13 Ahau, 3, 6, the right hand dot of the 3 being erased.

On pages 23 and 24 the brilliant backgrounds of the preceding pages disappear, and we have two pages, to be read together, of glyphs, day-signs and small figures, finely and sparingly illuminated with the usual four colors. The body of the dragon is apparently continuous from page 21, and crosses these pages entirely with the constellation band, displayed along its full length.

The upper part of these two pages contained originally 91 glyphs, perhaps to be read from right to left, the same as 21 and 22. The faces look to the right, the usual prefixes and the few numerals are also on the right of their respective compounds. Many of the glyphs are the same as those on pages 2 to 11, reversed right for left. Glyph 23-a-11 should be specially noted. At first sight the numeral prefix, 6, appears to belong, postfixed, to glyph 23-a-17. But on investigation we find the same compound, a yax-chuen with prefix, also at 21-a-8 and 24-a-26, in each case with the 6 attached. The affix just below this number 6 is also plainly a prefix to glyph 23-a-12; so that glyph 23-a-ll must be read and include the 6 as prefix. At 24-a-26, the same glyph is written left to right.

There are also a few other glyphs on these pages which cannot be regarded as right to left. Such for instance, as at 23-a-19 and 24-a-17. In this glyph the affix at the side is properly a prefix (perhaps the possessive), and I do not recall any instance of its use as a postfix. In the affixes, the superfix and prefix positions may as a general rule be regarded as wholly identical; also the subfix and postfix positions. But also as a general rule the two pairs are I believe not to be interchanged, any more than we interchange prefixes and endings in English; this rule is not universal for all affixes, as some seem able to go anywhere, but it is one I have always regarded in my glyph classifying.
