Reducing' these periods (5 cycles, ll» Ivatuus, l^i aliaus, 12 chneus, 8 

 days) to days, we tjet the following i-esiilt: 



Days 



5 cycles 720,000 



lOkatuns 136,800 



13iihims _ 4,680 



12 chuens___ . 240 



8 ilays 8 



Total 861,728 



Subtracting 45 calendar ronnds _ , 854, 100 



Eemainder 7, 628 



Counting forward 7,(528 days from 7 Kan -2 Zae, year 1 Akbal, we 

 reach 4: Eb 5 Chen, year 9 Lamat, which is the proper date. 



The demonstration therefore seems to be complete that Kau, in 

 the cases referred to, is the first day f)f eacli of the great cycles. It 

 is also important to notice that the numbers of these Kaus follow one 

 another in precisely the same order as do those of the Ahaus when 

 20 cycles are counted to tlie great cycle (see page 230) to wit: 9, 2, 8, 

 1, 7, and, if the series is continued by calculation, 13, 0, 12, 5, 11, 4, 

 10, 3, 9, 2, etc. 



If we ai'range these first days of the great cycles in the order in 

 which they come, adding the days of the month on which they fall, 

 they will be as follows — the numbering (column at the left) being, of 

 course, purely arbitrary: 



1 2 Kan 17 Cumhu. year 10 Lamat 



2 8 Kan 2 Mol, year 10 Akbal 



3 1 Kanl2]V[uan, 



4 7 Kan 17 Zotz 



5 13 Kan 7 Cell, 



6 . _ . 6 Kan 12 Pop, 



7 12 Kan 2 Chen. 



8 5 Kan 12 Pax. 



9 11 Kan 17 Tzec, 



10 4 Kan 7 Mac, 



11 10 Kan 12 Uo, 



12 3 Kan 2 Yax.

30 ...... 1 2 Kan 7 Muan . year 1 2 Ezanab 



This is calculated from 9 Kan 12 Kayab as a basis, becaiise we have 

 found it to be such for some of the series of the Dresden codex. 



In ordei' to add proof to our explanjition and calculation of the 

 sei'ies in the serpent figures of plate LXii of the code.x, I show the result
