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 following 9.12.8.14.0 11 Ahau 3 Pop. Therefore our four possible terminal 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 01 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 immediately 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 0 or 1. Comparing the glyph in B4 with the day signs in figure [16], the form here recorded will be found to be identical 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

we have just seen appears in B4. This further proves that the kin coefficient in A4 is 1. The final confirmation of this identification will come from the month glyph, which must be 4 Pop if we have correctly identified the day as 12 Imix. If, on the other hand, the day were 11 Ahau, the month glyph would be 3 Pop. Passing over A5 B5, A6 B6, C1 D1, and C2, we, reach in D2a the closing glyph of the Supplementary Series, here showing the coefficient 9. Compare this form with figure [65]. The month glyph, therefore, should appear in D2b. The coefficient of this glyph is very clearly 4, thus confirming our identification of B4 as 12 Imix. (See Table [VII].) And finally, the month glyph itself is Pop. Compare D2b with figure [19], a. The whole Initial Series in plate [9], B, therefore reads 9.12.8.14.1 12 Imix 4 Pop.

In plate [10], is figured the Initial Series from Stela 3 at Tikal.[[147]] The introducing glyph, though somewhat effaced, may still be recognized in A1. The Initial-series number follows in B1-B3. The head-variant period glyphs are too badly weathered to show the determining characteristic in each case, except the uinal head in A3, the mouth curl of which appears clearly, and their identification rests on their relative positions with reference to the introducing glyph. The reliability of this basis of identification for the period glyphs of Initial Series has been thoroughly tested in the texts already presented and is further confirmed in this very inscription by the uinal head. Even if the large mouth curl of the head in A3 had not proved that the uinal was recorded here, we should have assumed this to be the case because this glyph, A3, is the fourth from the introducing glyph. The presence of the mouth curl therefore confirms the identification based on position. The student will have no difficulty in reading the number recorded in B1-B3 as 9.2.13.0.0.

Reducing this number by means of Table [XIII] to units of the first order, we obtain:

B1 = 9 × 144,000 = 1,296,000
A2 = 2 × 7,200 = 14,400
B2 = 13 × 360 = 4,680
A3 = 0 × 20 = 0
B3 = 0 × 1 = 0

1,315,080

Deducting all the Calendar Rounds possible from this number, 69 (see Table [XVI]), and applying rules 1, 2, and 3 (pp. [139], [140], and [141], respectively) to the remainder, the terminal date reached will be 4 Ahau 13 Kayab. It remains to find this date in the text. The glyph in A4, the proper position for the day glyph, is somewhat effaced, though the profile of the human head may yet be traced, thus enabling us to identify this form as the day sign Ahau. Compare figure [16], h', i'. The coefficient of A4 is very clearly 4 dots, that is, 4, and consequently this glyph agrees with the day as determined by calculation, 4 Ahau. Passing over B4, A5, B5, and A6, we reach in B6 the closing glyph of the Supplementary Series, here recorded with a coefficient of 9. Compare B6 with figure [65]. The month glyph follows in A7 with the coefficient 13. Comparing this latter glyph with the month signs in figure [19], it is evident that the month Kayab (fig. [19], d'-f') is recorded in A7, which reads, therefore, 13 Kayab. Hence the whole text records the Initial Series 9.2.13.0.0 4 Ahau 13 Kayab.
