s to be as follows, filling out the effaced ones in the
line:

_Cipactli_, 1, 8, 2, 9, 3, 10, 4, 11, 5, 12, 6, 13, 7 (the symbol being
repeated with each number.)[TN-10]

[Illustration: FIG. 5.--Copy of Plates 51 and 52, Vatican Codex B.]

In the next, the lower right-hand square on Plate 61, where the day is
Coatl, the numbers, reading the same way, are as follows (filling out
one effaced one):

_Coatl_, 5, 12, 6, 13, 7, 1, 8, 2, 9, 3, 10, 4, 11.

Taking the lower left-hand square next, the day Atl, and reading in the
same direction, we find the numbers to be as follows (filling out two
effaced groups):

_Atl_, 9, 3, 10, 4, 11, 5, 12, 6, 13, 7, 1, 8, 2.

We take the upper left hand next, reading from left to right and up:

_Acatl_, 13, 7, 1, 8, 2, 9, 3, 10, 4, 11, 5, 12, 6.

Lastly, the upper right-hand square, reading the same way as the last.

_Ollin_, 4, 11, 5, 12, 6, 13, 7, 1, 8, 2, 9, 3, 10.

We have only to turn to our abridged calendar (Table III) to find this
explained. If we take the Ix column and select every fourth day, to wit,
Ix, Ezanab, Ik, Cimi, and Oc, and read the line of numbers opposite
each, we shall find them corresponding precisely with those mentioned
here. For instance, those opposite _Ix_ the same as those opposite
_Cipactli_, &c.

We further notice that these five names, _Cipactli_, _Coatl_, _Atl_,
_Acatl_, and _Ollin_, or, to use the English names, Dragon, Snake,
Water, Cane, and Movement, are precisely those of column 1 of the
arrangement of the Mexican days as heretofore given (Table XI).

On plates 13-17 of the Vatican Codex, B, Kingsborough, Vol. III, we find
precisely the same arrangement as that just described, and where the
numerals are so distinct that there can be no doubt in regard to any of
them. The days are exactly the same--Cipactli, Coatl, Atl, Acatl, and
Ollin--and in the same order, but the plates are to be taken in the
reverse, order, commencing with 17, and the columns and lines are to be
read thus: Commencing at the bottom at the right hand, upward to the
top, and then along the line toward the left.

On Plate 58 of the Borgian Codex we find six lines of days with five in
each line. Five out of these six lines are composed of the five days
just named, simply varied as to the respective positions they occupy in
the line, but maintaining the same order.

On Plate 17, same Codex, we see two lines corresponding with the first
and second columns of the arrange
