Table XIX.— Table of numeral and dun ■VP»^>'^I'<- (Plate 586.) 



The spaces in the lists indicate tlie positions of the pictures of per- 

 sons and curtain-like ornaments inserted here and there, as seen in 

 Figs. 363-370. 



In order to explain this sei'ies, we commence with that portion of 

 it foimd in the lower division of Plate 51 (Fig. 363). 



Omitting any reference for the present to the black numbers over 

 the day columns, we call attention first to the days and to the red 

 numerals attached to them. Those in the division selected as an 

 illustration are as follows: 



IV Ik. XII Cauac. VII Cib. 



VAkbal. XIII Ahau. VIII Caban. 

 VI Kan. I Ymix. IX Ezaiiab. 



II Been. 



III Ix. 



IV Men. 



X Oc. II Ezanab. 



XI Chuen. Ill Cauac. 

 XII Eb. IV Ahau. ' 



It will be observed that the week numbers of the days in each 

 single column follow one another in regular arithmetical order, thus : 

 in the first column, 4, 5, 6; in the second, 12, 13, 1; in the third, 7, 

 8, 9; and so on throughout the entire series. The interval, there- 

 fore, between the successive days of a column is 1 ; or, in other words, 

 the days follow one another in regular order, as in the mouth series, 

 so that having the first day of a column given we know at once the 

 other two. It is apparent, therefore, that the intervals between the 

 three correspondingly opposite days of any two associate columns are 

 the same; that is to say, the interval between 5 Akbal and 13 Ahau, 

 in the first two columns given above is the same as that between 4 Ik 

 and 13 Cauac, and also as that between 6 Kan and 1 Ymix. This is 

 also true if the attached week numbers are omitted; for instance, 

 the interval between Ik and Cauac, counting on the list of days form- 

 ing the month, is 17 days, and it is the same between Kan and Ymix. 

 Taking the second and third columns we find here the same interval. 

 Tliis holds good in that part of the series above given until we reach 

 the last two columns; here the interval between Oc and Ezanab is 8 

 days and it is the same between the other days of these two columns. 



' The third symbol in the last day column of Plate 516 is Been in the codex; but 

 this is an evident mi.stake, as shown by the order of the days, since Ahau, which has 

 been substituted above, always follows Cauac. This may be seen by reference to 

 the middle column of 576.
