248 THE INSCRIPTIONS AT COPAN. 
sign coefficient is surely 9 -y-y and if the terminal date of this series is 
12 Muluc 7 Muan (Date 8), ie the day-sign in Eb must be Cauac. This 
is true because the kin coefficient of the Secondary Series in cb is unmistak- 
ably 10, and 10 backward from Muluc gives Cauac. 
The kin coefficient in cb, however, is the only coefficient in this Second- 
ary Series which is certain. The uinal coefficient cb appears to be composed 
of one bar and four dots, 7. e., 9, but this is somewhat doubtful. ~~~ 
The tun coefficient, pa, is the highest in the series. There seems to be 
room for anumber between 11 and 15, inclusive, that is, a number composed of 
two bars and one or more dots, or three bars. In support of this higher value 
for the tun coefficient than those of the uinal and katun, it should be noted 
that the tun-sign is lower than the katun and uinal-signs on each side of it, 
as though more space had been necessary for its coefficient. The katun 
coefficient is above 5 and below 11 and probably below to. 
Returning once more to our postulate that Dates 7 and g are the same, 
we can now fill in the destroyed day of Date 7 as 9 Cauac (the day of Date 
g), and Date 7 then becomes 9 Cauac 17 Yaxkin. 
Our problem, then, is to find an Initial Series for g Cauac 17 Yaxkin 
which can be joined to 9.13.18.17.9 12 Muluc 7 Muan (Date 8), by the 
Secondary Series in cb, D on Step K. 
Since the katun coefficient of this Secondary Series is either 6, 7, 8, 9, 
or 10, Date 7 must be in Katuns 3, 4, 5, 6, or 7. By referring to Goodman’s 
tables, it will be found that g Cauac 17 Yaxkin occurred only thrice in these 
five katuns, as follows: 9.3.11.12.19, 9.6.4.7.19, and 9.8.17.2.19. Subtracting 
each one of these dates from 9.13.18.17.9, one of the resulting differences 
should, if our procedure and postulate be correct, correspond with the 
Secondary Series in cb, D: 
G.13118.17;-0 9.13.18.17)' 9 9.13.18.17. 9 
Q. 3. L1s12s19 0. G4): 2.99 9. B17. 2.19 
10; "7s 4010 Ths OKC 5. Tsl4ato 
A comparison of these differences with the several coefficients of the 
Secondary Series in cb—p shows clearly that the second, 7.14.9.10, is the only 
one possible here. ‘The best value of the uinal coefficient above was seen to 
be 9, and the tun coefficient was seen to be between Io and 16 exclusive; 
finally, the katun coefficient is between 5 and 11 exclusive. Both the first 
and third differences disagree for each of these values, as determined by 
inspection, and it therefore may be concluded, if our postulate is correct, 
that Dates 7 and 9 are 9.6.4.7.19 g Cauac 17 Yaxkin, and that the Secondary 
Series in cb—p, Step K, connecting Dates 7 and 9 with Date 8, is 7.14.9.10, 
viz: 
Dates 7 and 9979.26.04 9-90 g Cauac 17 Yaxkin

Date 8 9.13.18.17. 9 12 Muluc 7 Muan
