s been
observed in regard to the red numerals at the bottom of the plates. To
test this and also for the reason that we propose to discuss their
relations and their use, we give here the bottom line of days of each of
the five series (or plates), together with their week numbers attached;
also, the numbers of the three lines of black numerals mentioned, taking
them in the order of the paging as here shown:

_Plate_ 46:
VIII Cib. VII Cimi. X Cib. V Kan.
1 1
11 16 10 11
16 6 16 4

_Plate_ 47:
VII Ahau. VI Oc. IX Ahau. IV Lamat.
2 2 3 3
5 9 4 4
0 10 0 8

_Plate_ 48:
VI Kan. V Ix. VIII Kan. III Eb.
3 4 4 4
16 2 15 15
3(?) 14 4 12

_Plate_ 49:
V Lamat. IV Ezanab. VII Lamat. II Cib.
5 5 6 6
9 13 8 8
8 18 8 16

_Plate_ 50:
IV Eb. III Ik. VI Eb. 1 Ahau.
7 7 8 8
3 7 1 2
12 2 12 0

In considering these horizontal lines it is to be understood that the
series runs through the five pages, 46-50.

Let us proceed upon the supposition that the figures of the lowest of the
three lines denote days of the month, the numbers of the middle line
months, and those of the upper line years. As already shown, the interval
between 8 Cib and 7 Cimi is 4 months and 10 days; adding 4 months and 10
days to 11 months and 16 days (bearing in mind that 20 days make a month
and 18 months a year), the sum is found to be 16 months and 6 days,
precisely the figures under 7 Cimi. As already ascertained, the interval
between 7 Cimi and 10 Cib is 12 months and 10 days; this added to 16
months and 6 days gives 1 year, 10 months, 16 days, precisely the figures
under 10 Cib. The interval between 10 Cib and 5 Kan is 8 days; this added
to the 1 year, 10 months, and 16 days gives 1 year, 11 months, and 4
days, the figures under 5 Kan. The interval between 5 Kan and 7 Ahau is
