Commencing with 3 Lamat on our calendar and counting 26 days brings us to 3 Ix; 26 more to 3 Ahau; 26 more to 3 Cimi, and so on to the end.
In the lower division of Plate 9 is a series arranged as follows:
| III | III | VI | VIII | |
| Cauac | Been | 3 | 2 | |
| Chuen | Chicchan | { | XI 3 | II 4 |
| Akbal | Caban | { | VI 4 | VII 1 |
| Men | Muluc | I | III | |
| Manik | Ymix | 7 | 2 |
The sum of the black numerals is 26 and the final red number is III, the same as that over the columns. The interval between the days, taken alternately from the two columns, as in the preceding example, is 26. The numbers are also to be taken alternately from the two number columns.
It is apparent that these examples sustain the theory advanced. This will also be found true in regard to all the series of this type in this and the other codices where the copy is correct. Brasseur’s copy of the Manuscript Troano is so full of mistakes that no satisfactory examination of this codex can be made until a photographic copy is obtained; nevertheless a few examples are given as proof of the above statement.
In the third division of Plate XI* is the following series:
| IV | ||
| Ahau | } | |
| Eb | 17, VIII; 13, VIII; 10 V; 12, IV. | |
| Kan | ||
| Cib | ||
| Lamat |
As will be readily seen, after the explanations given, this agrees with the theory advanced.
The last red number is the same as that over the day column, the sum of the black numbers is 52, and the interval between the days 52.
Commencing in the right margin of the lowest division of Plate XXIII* and running through Plates XXII* and XXI*, is the series here represented:
