between the tun coefficient and the tun sign in A3, which is repeated 

 again in D3 between the month coefficient and the month sign, is 

 unknown. 



In phxte 9, B, is figured the Initial Series on an altar in front of 

 Structure 44 at Yaxchilan.^ The introducing glyph appears in Al Bl 

 and is followed by the number in A2-A4. The period glyphs are all 

 expressed as head variants and the coefficients as bar and dot numerals. 

 Excepting the kin coefficient in A4, the number is quite easily read 

 as 9.12.8.14. ? An inspection of our text shows that the coefficient 

 must be 0, 1, 2, or 8. Let us work out the terminal dates for all four 

 of these values, commencing with 0, and then see which of the result- 

 ing terminal days is the one actually recorded in A4. Reducing the 

 number 9.12.8.14.0 to units of the first order by means of Table 

 XIII, we have: 



A2= 9X144,000 = 1,296,000 



B2 = 12 X 7, 200 = 86, 400 



A3= 8X 360= 2,880 



B3 = 14 X 20 = 280 



A4= OX 1= 



1, 385, 560 

 Deducting from this number all the Calendar Rounds possible, 73 

 (see Table XVI), and applying rules 1, 2, and 3 (pp. 139, 140, and 

 141, respectively), to the remainder, the terminal day reached will be 

 11 Ahau 3 Pop. Therefore the Initial-series numbers 9.12.8.14.1, 

 9.12.8.14.2, and 9.12.8.14.3 will lead to the three days immediately fol- 

 lowing 9. 12.8. 14.0 11 Ahau 3 Pop. Therefore our four possible termi- 

 nal dates will be: 



9.12.8.14.0 11 Ahau 3 Pop 



9.12.8.14.1 12 Imix 4 Pop 



9.12.8.14.2 13 Ik 5 Pop 



9.12.8.14.3 1 Akbal 6 Pop 



Now let us look for one of these four terminal dates in the text. The 

 day reached by an Initial Series is almost invariably recorded imme- 

 diately after the last period glyph; therefore, if this inscription is 

 regular, the day glyph should be B4. This glyph probably has the 

 coefficient 12 (2 bars and 2 numerical dots), the oblong element 

 between probably being ornamental only. This number must be 

 either 11 or 12, since if it were 13 the 3 dots would all be of the same 

 size, which is not the case. An inspection of the coefficient in B4 

 eliminates from consideration, therefore, the last two of the above 

 four possible terminal dates, and reduces the possible values for the 

 kin coefficient in A4 to or 1. Comparing the glyph in B4 with the 

 day signs in figure 16, the form here recorded will be found to be iden- 

 tical with the sign for Imix in figure 16, a. This eliminates the first 

 terminal date above and leaves the second, the day part of which
