omplete cycles of 13 months, or 260 days each. Counting back three
months and five days from 4 Caban (the day in the fifth column, middle
division, of Plate 73) we reach 5 Been as the starting point of the
series.

As there can be no doubt that the lines and days of the two divisions
form together one unbroken series, it is evident there is no connection
between that portion of it in the middle division and what lies to the
left of it in Plate 71; but there does appear to be, as before indicated,
some connection between the conclusion and what follows to the left in
the lower portion of 71. The series which lies to the left at this point
is as follows:

TABLE XXIV.--_Table showing relations of Plates 70 and 71._

________________________________________________________________
Plate 70. | Plate 71.
----------------+-----------------------------------------------
5th | 6th | 1st | 2d | 3d | 4th | 5th | 6th
column.|column. |column.|column.|column.|column.|column.|column.
6 | 5 | 4 | 3 | 2 | | |

---------------------------------------------------------------

For the purpose of assisting the reader to see the relation more clearly,
the last column of the preceding series--sixth of the lower division on
Plate 71--is added at the right as it stands in the original.

It is apparent that the figures in the fifth column of 71 are exactly
double those in the sixth column. This and the fact that the day IV Eb is
the same as those following are the only indications that there is any
connection between the series. Using the 5 years and 1 month as the
common difference and adding, the result is as follows:

Years. Months. Days.
5 1 0 Sixth column, lower division, Plate 71.
5 1 0
-- -- --
10 2 0 Fifth column, lower division, Plate 71.
5 1 0
-- -- --
15 3 0 Fourth column, lower division, Plate 71.

At this point another change occurs: the former difference is added to
the last figures and the sum is doubled.

Twenty year periods. Years.
