are the large pendulous nose surmounted by a curl, the bulging eye, 

 and the mouth fang, the last mentioned not appearing in this case. 

 Since the kin coefficient in B3a is somewhat effaced, let us call it 

 for the present^ and proceed to reduce our number 9.8.9.13.0 to units 

 of the first order by means of Table XIII : 



Bl= 9X144,000 = 1,296,000 

 A2= 8X 7,200= 57,600 

 B2= 9X 360= 3,240 



A3 = 13X 20= 260 



B3= Ox 1= 



1, 357, 100 



Deducting from this number all the Calendar Rounds possible, 71 

 (see Table XVI), and applying rules 1, 2, and 3 (pp. 139, 140, and 141, 

 respectively) to the remainder, we reach as the terminal date 8 Ahau 

 13 Pop. Now let us examine the text and see what is the terminal 

 date actually recorded. In A4b the student mil have little difficulty 

 in recognizing the profile variant of the day sign Ahau (see fig. 16, 

 Ti', i'). This at once gives us the missing value for the kin coefficient 

 in B3, for the day Ahau can never be reached in an Initial Series if 

 the kin coefficient is other than 0. Similarly, the day Imix can never 

 be reached in Initial Series if the kin coefficient is other than 1, etc. 

 Every one of the 20 possible Idn coefficients, to 19, has a corre- 

 sponding day to which it will always lead, that is, Ahau to Cauac, 

 respectively (see Table I). Thus, if the kin coefficient in an Initial- 

 series number were 5, for example, the day sign of the resulting 

 terminal date must be Chicchan, since Chicchan is the fifth name after 

 Ahau in Table I. Thus the day sign in Initial-series terminal dates 

 may be determined by inspection of the kin coefficient as well as by 

 rule 2 (p. 140), though, as the student will see, both are applications 

 of the same principle, that is, deducting all of the 20s possible and 

 counting forward only the remainder. Returning to our text, we 

 can now say without hesitation that our number is 9.8.9.13.0 and 

 that the day sign in A4b is Ahau. The day coefficient in A4a is just 

 like the katun coefficient in A2a, having the same determining char- 

 acteristic, namely, the forehead ornament composed of one part. A 

 comparison of this ornament with the ornament on the head for 8 

 in A2a will show that the two forms are identical. The bifurcate 

 ornament surmounting the head in A4a is a part of the headdress, 

 and as such should not be confused with the forehead ornament. 

 The failure to recognize this point might cause the student to identify 



1 It is clear that if all the period coefTicients above the kin have been correctly identified, even though 

 the kin coefficient is unknown, by designating it the date reached will be within 19 days of the date 

 originally recorded. Even though its maximum value (19) had originally been recorded here, it could 

 have carried the count only 19 days further. By using as the kin coefficient, therefore, we can not be 

 more than 19 days from the original date.
