DAY GROUPS IN THE MEXICAN CODICES.

Iii the next, the lower right-hand square 

 on Plate 61, where the day is Coatl, the 

 numbers, reading the same way, are as 

 follows (tilling 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 (tilling 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, read- 

 ing 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. p 



Ollin, 4, 11, o, 12, 6, 13, 7, 1, 8, 2, 9, 3, 10. f

We have only to turn to our abridged | 

 ■calendar (Table III) to tind this explained. 2, 

 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 op- g 

 posite each, we shall find them corres- g 

 ponding 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, a 

 to use the English names, Dragon, Snake, 

 Water, Cane, and Movement, are pre- 

 cisely those of column 1 of the arrange- 

 ment of the Mexican days as heretofore 

 given (Table XI). 



On plates 13-17 of the Vatican Codex, 

 B, Kingsborough, Vol. Ill, we find pre- 

 cisely 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 re- 

 verse order, commencing with 17, and 

 the columns and lines are to -be read
