168 THE INSCRIPTIONS AT COPAN. 
This leaves but one glyph unexplained, 0’, 7. ¢., the one immediately 
preceding the foregoing. This is composed of a bar, 7. ¢., 5, prefixed to a very 
clear death’s head, which is in every way similar to the death’s heads repre- 
senting the number to found elsewhere. We would appear to have in this 
glyph, then, a composite numeral, a bar-and-dot 5 joined to a head-variant 
10 exactly as in the tun coefficients on the East Altar of Stela 5 and probably 
Stela 12. Compare Glyph 0’, figure 30, with ca u. h., plate 20, d, and it 
will be found that the parallel is complete. But we have already seen that 
in the latter case these are strong—indeed well-nigh irrefutable—reasons for 
believing that these two numerical elements are joined by addition, and 
not by multiplication, which, if true, would give for b’ the meaning 15, 7. ¢., 
5S+I10o=1I5. 
Moreover, the right-hand glyph, 0”, has no coefficient at all, whereas the 
same glyph in the upper line, 5, has a coefficient of 10. Therefore it seems 
not unlikely that Glyph b’ may be joined to b’’, making 15 times the gro- 
tesque head for the lower line instead of 10 times, as it is in the upper line. 
That these two numerals, one a bar-and-dot and the other a head-variant, 
are joined to each other by addition and to the glyphs they modify by 
multiplication, is probably true here. Moreover, such an arrangement 
completes the parallel between the upper and lower lines, since in this event 
there would then be only 6 glyphs in each of these Supplementary Series, 
and the fifth glyph in each, counting from the right, 7. ¢., b and b’b’’, would 
then be the same, having a coefficient of 10 in the upper line and of 15 in the 
lower line. 

Fig. 31.—Glyphs showing composite numerals from: a and g, Yaxchilan, Lintel 21; b, Yaxchilan, Lintel in 
Berlin Museum; c, Yaxchilan, Lintel 29; d, Palenque, Temple of the Cross; ¢, Copan, Stela 
12; f, Copan, East Altar of Stela 5. 
The other examples (see figure 31) are all from Supplementary Series 
at Yaxchilan, where use of this composite type of numeral seems to have 
been quite common. The first example (figure 31, a) is from Lintel 21, Struc- 
ture 22. Here a bar is prefixed to a death’s head, this composite numeral 
being attached to a sign which, the writer has shown elsewhere,' is a variant 
of the kin-sign. ‘The whole glyph would appear to record 15 kins. Notice 
should be taken of the five dots in the death’s head, also a characteristic of 
the death’s head in the Palenque text. (See figure 30, b’, and figure 31, g.) 
The second example (figure 31, 2) is froma lintel in the Berlin Museum. 
Again there is the same bar, here standing above the same death’s head;
