ion of whether a simple
number-round of thirteen terms, or a full round of twenty terms, whether
tuns or katuns, was originally displayed on the Codex, must be left
undetermined. It is further to be noted that faint but exact traces of a
third Ahau, on a higher line, appear on page 5, as well as some doubtful
traces on page 8. No definite relationship between the pictures of this
section _a_ and those of section _e_ is apparent.

Section _b_ is made up of 45 or more glyphs in three columns. The first
column is almost totally erased on every page, and I have disregarded it
both in assigning reference numbers and in the type cards. The other two
columns I have numbered in double column sequence downwards; but this
can be regarded as solely for convenience' sake. The glyph [Hieroglyph]
which is three times repeated at the beginning of page 2, and recurs in
parallel position repeated two to five times on each page, is the most
common glyph in the whole Codex. It is identifiable probably 38 times,
including twice at the top of the erased _first_ column on page 4. It
heads the second column several times on every page, except 7, which is
too erased for any determination, and page 3, where a slight variation
in what is left of the postfix at b-3 forbade its insertion under the
rules I have given limiting restorations. I suspect that this glyph
should be repeated at 3-b-9 and 11-b-9, for the following reason. In
positions b-6, b-8 or b-10 of each page occurs a certain face-glyph
[Hieroglyph] that is found nowhere else in either the Perez, Dresden or
Tro.-Cort. codices. If the initial glyph is repeated at 3-b-9 and 11-b-9
as suggested, then (with a slight variation on page 4) this series of
repetitions of the initial glyph will in each case be closed by the
face-glyph in question.

A marked feature of section _b_ is the occurrence, near the bottom of
each page, of a Cauac-sign, with or without the [Hieroglyph]
wing-postfix, and with prefixed and superfixed [Hieroglyph] numerals,
exactly as is so common in connexion with the Chuen-sign on the
Inscriptions. This Cauac-sign is usually accompanied by an Ahau and a
Tun, each with numerals that are for the most part erased. This
combination suggests distance-numbers and dates, somewhat as on the
Inscriptions; in this case the double-numbered Cauacs would stand for so
many uinals plus so many days. The following combinations, besides the
one above, are also found:
