Now for the proof that it is designed for the same purpose as the looped line on the other plate. But it is necessary that I present first, in a tabular form, a Mexican calendar ([Table XIV]) similar to the condensed Maya calendar heretofore given.
I also give, immediately following, a list of Mexican days for thirteen months, the number necessary to make the circuit of the plate, just as the list of Maya days heretofore given. In this case I have used the English equivalents of the Mexican words for the benefit of English readers.

This calendar begins the year Acatl with Cipactli to correspond with what I believe to have been the plan on which the Fejervary plate was made; this, as will be seen, does not agree with what is generally supposed to have been the usual method. The following table of days can be used for either year, but commences as the Acatl years in the preceding calendar.
