The uinal and its coefficient in A3 are equally clear. The period glyph here appears as a frog (Maya, _uo_), which, as we have seen {190} elsewhere, may have been chosen to represent the 20-day period because of the similarity of its name, _uo_, to the name of this period, _u_, or uinal. The head of the anthropomorphic figure which clasps the frog's foreleg is the head variant for 0. Note the clasped hand across the lower part of the face, and compare this form with figure 53, _s-w_. The whole glyph, therefore, stands for 0 uinals. In B3 are recorded the kin and its coefficient. The period glyph here is represented by an anthropomorphic figure with a grotesque head. Its identity, as representing the kins of this number, is better established from its position in the number than from its appearance, which is somewhat irregular. The kin coefficient is just like the uinal coefficient--an anthropomorphic figure the head of which has the clasped hand as its determining characteristic. Therefore B3 records 0 kins. The whole number expressed by B1-B3 is 9.15.5.0.0; reducing this by means of Table XIII to units of the first order, we have: B1 = 9 × 144,000 = 1,296,000 A2 = 15 × 7,200 = 108,000 B2 = 5 × 360 = 1,800 A3 = 0 × 20 = 0 B3 = 0 × 1 = 0 --------- 1,405,800 Deducting from this number all the Calendar Rounds possible, 74 (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 10 Ahau 8 Chen. The day part of this terminal date is recorded in A4. The day sign Ahau is represented as an anthropomorphic figure, crouching within the customary day-sign cartouche. The head of this figure is the familiar profile variant for the day sign Ahau, seen in figure 16, _h', i'_. This cartouche is clasped by the left arm of another anthropomorphic figure, the day coefficient, the head of which is the skull, denoting the numeral 10. Note the fleshless lower jaw of this head and compare it with the same element in figure 52, _m-r_. This glyph A4 records, therefore, the day reached by the Initial Series, 10 Ahau. The position of the month glyph in this text is most unusual. Passing over B4, the first glyph of the Supplementary Series, the month glyph follows it immediately in A5. The month coefficient appears again as an anthropomorphic figure, the head of which has for its determining characteristic the forehead ornament composed of one part, denoting the numeral 8. Compare this head with the heads for 8, in figure 52, _a-f_. The month sign itself appears as a large grotesque head, the details of which present the essential elements of the month here recorded--Chen. Compare with figure 19, _o, p_.
