EXEECISES EST DECIPHERMENT. 107 



FIFTH AHATJ.— 1S00 days. 



2nd glyph — 18x40 = 720x2 = 1440; hence this glyph should have gone with the 

 pi-eceding ahau. 



3;y7 glyph. — A symbol which appropriately denotes the beginning of a 5th ahau in 

 several other places in the inscriptions. I call attention to the peculiar character of 

 the wing, or whatever it may be termed. It is not the ordinary form, signifying 20, 

 but must have the value of 36— 10x5 = 50 X 36 = 1800. 



SIXTH AHAU.— 2160 days. 



2nd glyph. — The under number being 4 here, the character above the coils should 

 represent 30, but instead it represents only 25 — 18x25 = 450x4=1800; hence this 

 glyph should have gone with the 5th ahau. 



3rd glyph- — The 20-day sign again, qualified by a character which the connection 

 requires to be a sign for 10S— 108x20=2160. 



Ath glyph. — An arbitrary sign, probably, for sis ahaus or -a 6th ahau. 



SEVENTH AHAU.— 2520 days. 



2nd glyph.— IS X 4 = 72 x 35 = 2520. 



3rd glyph. — Two of the characters encountered above reappear here, associated with 

 a knot, which we know to be a sign for 5 or some of its multiples. As neither 10, 15, 

 nor 20, added to the other characters, would form a number that would be an even 

 divisor of 2520, we must consider this a sign for 5, and the character underneath it to 

 represent 60—10 + 27 + 5 = 42x60 = 2520. The subfix here, consequently, notwith- 

 standing its resemblance to the character representing 72, can have no value, but must 

 serve merely as a pedestal, as it does under the day symbols. 



EIGHTH AHAU.— 2880 days. 



2nd glyph.— 18x40=720x4=2880. 



ord glyj)h.—lSx 40=720 x 4 = 28S0. The subfix is without value here also. 



ith glyph. — Too defaced to justify any estimate of it. 



NINTH AHAU.— 3240 days. 



The computation, if there was one, and the equivalents are defaced beyond the 

 possibility of recognition. 



TENTH AHAU.— 3000 days. 



The ahau sign here differs from all the rest. It is the symbol used in a Tikal tablet 

 to denote a date to be a 10th ahau.
