188 BUEEAU OF AMEEICAN ETHNOLOGY 



[BOLL. 51 



Deducting from this number all the Calendar Rounds possible, 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 )e 

 12 Ahau 8 Mol. This date is reached on the assumption that the miss- 

 ing kin coefficient was zero. This is a fairly safe assumption, since 

 when the tun coefficient is either 0, 5, 10, or 15 (as here) and the uinal 

 coefficient is (as here), the kin coefficient is almost invariably zero. 

 That is, the close of an even ho tun in the Long Count is recorded. 



While at Copan in May, 1912, the writer was shown a fragment of 

 a stela which he was told was a part of this monument (Stela 15). 

 This showed the top parts of two consecutive glyphs, the first of 

 which very clearly had a coefficient of 12 and the one following of 8. 

 The glyphs to which these coefficients belonged were missing, but the 

 coincidence of the two numbers 12 (?) 8 (?) was so striking when taken 

 into con^ideration with the fact that these were the day and month 

 coefficients reached by calculation, that the writer was jnchned to 

 accept this fragment as the missing part of Stela 15 which showed 

 the terminal date. This whole Initial Series therefore reads : 9.4.10.0.0 

 12 Ahau 8 Mol. It is chiefly interesting because it shows the earliest 

 use of head-variant numerals known. 



In the foregoing texts plate 12, A, B, figure 69, A, B, and figure 70, 

 the head-variant numerals 0, 1, 3, 4, 5, 6, 8, 9, 10, 13, 14, 15, 17, and 18 

 have been given, and, excepting the forms for 2, 11, and 12, these 

 include examples of all the head numerals.^ No more texts specially 

 illustrating this type of numeral will be presented, but when any of 

 the head numerals not figured above (2, 7, 11, 12, 16, and 19) 

 occur in future texts their presence wiU be noted. 



Before taking up the consideration of unusual or irregular Initial 

 Series the writer has thought best to figure one Initial Series the 

 period glyphs and numerals of which are expressed by full-figure 

 forms. As mentioned on page 68, such inscriptions are exceedingly 

 rare, and such glyphs, moreover, are essentially the same as head- 

 variant forms, since their determining characteristics are restricted 

 to their head parts, which are exactly like the corresponding head- 

 variant forms. This fact wiU greatly aid the student in identifying 

 the full-figure glyphs in the following text. 



In plate 14 is figured the Initial Series from Stela D at Copan.^ 

 The introducing glyph is recorded in Al. The variable central 

 element in keeping with the other glyphs of the inscription appears 

 here as a fuU figure, the lower part of which is concealed by the tun- 



> The characteristics of the heads for 7, 14, 16, and 19 will be found in the heads for 17,4, 6, and 9, respec- 

 tively.

' The student will note also in connection with this glyph that the pair of comblike appendages usually 

 found are here replaced by a pair of fishes. As explained on pp. 65-66, the fish represents probably the 

 original form from which the comblike element was derived in the process of glyph conventionalization. 

 The full original form of this element is therefore in keeping with the other full-figure forms in this text.
