By examining carefully the lines and columns of the middle and lower
divisions of the plates--those represented in Tables XXI and XXII--we
ascertain that the two together form one series; but, contrary to the
method which has prevailed in those examined, it is to be read from
_right_ to _left_, commencing with the right hand column of the lower and
ending with the left hand column of the middle division.

As proof of this we have only to note the fact that the series of black
numerals over the day columns ascends towards the left. Assuming the
lowest of the three lines to be days, the middle one months, and the
upper one years, the common difference is 4 months and 11 days. Numbering
the ten columns of each of our tables from left to right as usual and
adding successively the common difference, commencing with the tenth
column of the lowest division, of which Cib is the first day, the result
will be as follows:

Years. Months. Days.
