28() AIDS TO THE STUDY OF THE MAYA CODU'ES. 



buck uu our caleudar (Table II) (15 days from 1 Cliueii we reach 1 

 Cimi, and 65 more bring us to 1 Ymix. In like manner we find the 

 fourth day to be 1 Cib and the fifth 1 Ymix. The numbers in the 

 figure columns are to be taken alternately, thus: 5, VI; 8, I; 5, VI; 

 8, I, &c. 



These examples are sufficient to show that the series of the Manu- 

 script Troano are arranged upon the same plan and based upon the 

 same system as those of the Dresden Codex. The following exam- 

 ples from the Codex Cortesianus prove the same thing to be true in 

 reference to the series found in it. 



The first is taken from the lower division of Plates lu and 11,

The S in the line of numerals represents the usual symbol for 20. 

 The sum of the black numbers is 65, the interval between the days 

 65, and the last red numeral the same as that over the day column, 

 thus agreeing in plan with those in the other codices. 



The following double column series is found in the middle division 

 of Plate 30: 



XI XI 



Ahau Ymix ) 



Eb Been - 30 -|- 0. XI : 30 -f- 6, XI. 



Kan Caban ) 



Cib Chicchan 



Lamat Manik 



The number 20 is denoted by the usual symbol. The sum of the 

 black numbers is 53 and the interval between the days in each 

 column 52, but in this case there does not appear to be any connec- 

 tion between the columns, there being, in fact, two distinct series. 

 In the upper division of the same plate is this series: 



I 



XI 

 Ezanab 



Ik 



(VI XI 



"/ 8 .5 



(VI XI 



/ 8 r, 



(VI XI 



) 8 5 



( VI XI 



Ix 



Cimi 



The order in which these numerals are to be read is as follows: 8, 

 VI; 5, XI; 8, VI: 5, XI, &c. , which gives, as the final red number 

 of the series, XI, the same as that over the column. The sum of the 

 black numbers is 52 and the interval between the days 52. 



Taking for granted that the correctness of the theory advanced is 

 conceded, some attempts at its further application, especially its use 

 in making restorations and corrections in defective series and in 

 settling doTibtful questions relating thereto, will now be presented.
