THOMAS] EXPLANATION OF SERIES IN THE MANUSCRIPT TROANO. 285 



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 5:2, 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 : 



VII VII 



Cib Cimi 1 



Ik Eb - 7, I; 7, VIII; 7, II; 5, VII. 



Lamat Ezanab ) 

 Ix Kan 



Ahau Oc 



An examination of this shows it to be of the type of the double 

 column series of the other codex, except that here the days of one 

 ciiluinn are to be taken in the order in which they stand before y>vo- 

 ceciling to the other column. The sum of the black niimbers is 36 

 and the interval between 7 Cib and 7 Ik 36 days. The interval be- 

 tween 7 Ik and 7 Lamat, 7 Lamat and 7 Ix, and between 7 Ix and 7 

 Aliau is, in each case, 36 days. The interval between 7 Ahau, last 

 (lay of the left hand column, and 7 Cimi, -tlie first day of the right 

 hand column, is also 36 days. 



The order in which the days of these double column series of this 

 manuscript follow one another is not uniform, as in some cases (see 

 Plate XXV*. division n) they are to be taken alternately from the 

 two columns, as in the examples heretofore given from the Dresden 

 Codex. 



In the middle division (Plate XXXIII*, same codex) is a series of 

 the following form, but with the days so nearly obliterated that res- 

 toration is necessary: 



The symbol of the first day has only the upper circle of dots to 

 indicate that it is Ymix. that of the second day is almost obliterated, 

 the third is clearly Chuen, the lower half of the fourth is obliterated, 

 and the interior of the fifth is a blank. 



Fortunately there are sufficient data by which to make the restora- 

 tion. Chuen, we observe, is the middle of the column; that is, two 

 days are above it and two days below it; the sum of the black nu- 

 merals is 65; hence the interval between the days, considering the 

 week mimbers as attached, is 65, and the simple interval in the 

 month series, without regard to the week numbers, is 5. Counting
