indeed, in the text here under discussion, so far as we can judge from 

 the badly effaced glyphs, no Supplementary Series seems to have 

 been recorded. However, reversing oiu- operation, we know by 

 calculation that the month part should be Kayab, and by referring 

 to figure 49 we find the only form which can be used to express the 

 position with the month signs — ^the so-called ''spectacles" glyph — 

 which must be recorded somewhere in this text to express the idea 

 with the month sign Kayab. Further, by referring to figure 19, 

 d'-f , we may fix in our minds the sign for the month Kayab, which 

 should also appear in the text with one of the forms shown in figure 49. 



Returning to our text once more and following along the glyphs 

 after the day in A4, we pass over B4, A,5, and B5 without finding a 

 glyph resembling one of the forms in figure 49 joined to figure 19, 

 d'-f; that is, Kayab. However, m A6 such a glyph is reached, 

 and the student will have no difficulty in identifying the month sign 

 with d'-f in the above figure. Consequently, we have recorded in 

 A4, A6 the same terminal date, 9 Manik Kayab, as determined by 

 calculation, and may conclude, therefi.^re, tliat our text records without 

 error the date 9.12.15.13.7 9 Manik Kayab ^ of Maya chronology. 



The next text presented (pi. 6, C) shows the Initial Series from 

 Stela I at Quirigua.^ Again, as in plate 6, A, the introducing glyph 

 occupies the space of four glyph-blocks, namely. A1-B2. Immedi- 

 ately after this, in A3-A4, is recorded the Initial-series number 

 9.18.10.0.0, all the period glyphs and coefficients of which are 

 expressed by normal forms. The student's attention is called to the 

 form for used with the uuial and kin signs in A4a and A4b, respec- 

 tively, which differs from the form for recorded ^^dth the uinal and 

 kin signs in plate 6, A, B4, and A5, respectively. In the latter text 

 the uinals tind kms were expressed by the hand- and curl form for 

 zero showTi in figure 54; m the present text, however, the uinals 

 and kins are expressed by the form for sIioavti in figure 47, a new 

 feature. 



Reducing the above number to units of the 1st order by means of 

 Table XIII, we have: 



A3= 9X144,000 = 1,296,000 

 B3a = 18x 7,200= 129,600 

 B3b = 10x 360= 3,600 



A4a= Ox 20= 



A4b= Ox 1= 



1,429,200 



1 As will appear later, in connection with the discussion of the Secondary Series, the Initial-series date 

 of a monument does not always correspond with the ending date of tlie period wliose close the monument 

 marks. In other words, the Initial-series date is not always the date contemporaneous with the formal 

 dedication of 1 he monument as a time-marker. This point will apj)ear much more clearly when the fimction 

 of Secondary Series has been explained.
