552 THE INSCRIPTIONS AT COPAN. 
most important glyphs are at the end of the series, as will appear presently, and for 
this reason they were named first. The order of reading, however, as the glyphs 
follow each other in the inscriptions, is as follows: G, F, E, D, C, X, B, and A, the 
last usually immediately preceding the month-sign of the Initial Series terminal date 
as noted above. The relative frequency with which these glyphs occur in the 80 
texts under observation is as follows: 
Glyph A in 97 per cent. Glyph D in 50 per cent. 
B in 80 E in 30 
X in 93 F in 72 
C in 97 G in 35 
It will be seen from the foregoing tabulation that, on the basis of occurrence, 
Glyphs A and C are not only of equal importance, but also are of more importance 
than all the others. Then follows Glyph X, then Glyph B, and then the first four 
glyphs of the series, F, D,G, and E. These are relatively of much less importance 
than the last four, all except Glyph F occurring in half or less than half of the 80 
texts under observation. 
The glyphs of the Supplementary Series may be classified on the basis of a 
fundamental mathematical characteristic into two groups, as follows: (1) those 
which may have coefficients, including A, X, C, D, and E, and (2) those which 
never have coeficients, B, F, and G. Of these the second group is relatively of 
little importance in arriving at the meaning of this count, the gist of which seems 
to be expressed principally by Glyphs A, X, and C. 

Fic. 78.—Glyphs G, F, and B of the Supplementary Series: a—f/, Glyph G; g-/, Glyph 
F; m-r, Glyph B. The complete Supplementary Series from which these 
examples are taken are reproduced in Morley, 1916, plates 1-10. 
Let us examine the second group first. The writer has already expressed the 
opinion that Glyphs G, F, and B are signs of generalized meaning, and that they 
in no way affect the values of the Supplementary Series in which they are found. 
The first, Glyph G (see figure 78, a—f), when the Supplementary Series is in its 
normal position, 7. ¢., between the two parts of the Initial Series terminal date, 
always follows the day-sign; and when the Supplementary Series irregularly follows 
the Initial Series terminal date, it follows immediately after the month-sign; 
that is, by its immediate proximity to the day-sign it would appear to have had 
something to do with the diurnal count (7. ¢., the Initial Series) rather than with the 
lunar count proper; and this, moreover, 1s borne out by the internal evidence of the 
glyph itself, which, although it runs through a number of variants (see figure 78, 
a-f), both normal and head forms, is always to be recognized by the kin-sign which 
is invariably a part of it, and indeed is its only constant characteristic. The writer 
has already suggested the general meaning “this is the count of the days”’ or “‘here
