day of the first month in the calendar and tliird day of our column. 

 If the theory of the four year series be correct, then 1 Kan of the Kan 

 series must be the first day of the first year of an Indication or week 

 of years. This fact was probably considered by the aboriginal artist 

 of sufficient importance to give this day a mark of distinction. As it 

 is not possible for any of the other days of the column to be thus dis- 

 tinguished, it is fair to presume this peculiar marking of the final 

 number refers to Kan. Moreover, this distinction would not occur 

 if any other than the Kan series were used. 



In the iipper division of Plate IX of the same manuscript is the 

 following series: 



XIII 



Men I 



Manik 20, VII: 20 T : 1. II: 4. VI: 7. XIII. 



Cauac \ 



Chueii 



Akbal 



In this, I. the second red number of the series, has the circle of 

 dots around it. The number over the column is partially oblit- 

 erated, but is readily restored, and should be XIII. 



If we select, on our calendar, the Cauac column, or series, a reason 

 for this distinction will appear. The sum of the black numbers is 

 52, which is also the interval between the days. As has heretofore 

 been shown, the red numbers of the series refer to certain days 

 selected by the priests, for special reasons unknown to us, wliich 

 occur between the days of the column. 



In this case the intermediate days are as follows: 



Between 13 Manik and 13 Cauac: 7 Manik, 1 Manik, 2 Lamat, and 6 Eb. 



Between 13 Cauac and 13 Chuen: 7 Cauac, 1 Cauac, 3 Ahau, and 6 Kan. 



Here we find the explanation for which we are seeking, as in the 

 interval between 13 Cauac and 13 Chuen is 1 Cauac, which, if the 

 Cauac column of the calendar be selected, is the first day of the 

 year 1 Cauac. the first year of an Indication. As this occurs only 

 when a year commencing with Cauac is selected, we infer that the 

 series is based upon the system with the four year series. 



The best illustration of this peculiarity and the strongest evidence 

 of its sii;iiificatii)n is prdbably fnund in the series contained in the 

 niiildlf (livisidii, I'latr Xl.saun' manuscript. This, when written out 

 and till' nuiiilicrs prcipcrly arranged, is as follows:

The last black number of the series is 9, but should be 10 to render 

 the series complete. Making this correction, the series is of the usual 

 type: the sum of the black numerals is 20, the interval between the
