244 CENTRAL AMERICAN PICTURE-WRITING. 
BRASSEUR DE BoURBOURG has analyzed the signs for the day and 
month in his publication on the MS. Troano, and the strongest argu- 
ments which can be given for their phonetic origin are given by him. 
I have made a set of MS. copies of these signs and included them in 
my card-catalogue, and have carefully compared them with the tablets 
XXIV and LVI. My results are as follows: 
PLATE XXIV (our Fig. 60). 
No. 42 is the Maya month Pop, beginning July 16. 
No. 54 is Zip??, beginning August 25. 
No. 47 is Tzoz?2, beginning September 14. 
No. 57 is Tzec?, beginning October 4. 
No. 44-45 is Mol?, beginning December 38. 
No. 39 is Yaa, Zac, or Oeh, beginning January 12, February 1, Feb- 
ruary 21, respectively. 
PLATE LVI (our Fig. 48). 
No. 1804 is Uo???? No. 1807 is Mol? 
No. 1901 is Zip???? No. 1855 is Yaar, Zac, or Ceh. 
No. 1816 is Tzoz?? No. 1844 is Mac? 
No. 1814 is Tzec? 
The only sign about which there is little or no doubt is No. 42, which 
seems pretty certainly to be the sign of the Maya month Pop, which 
began July 16. 
No. 39, just above it, seems also to be one of the months Yaw, Zac, or 
Ceh, which began on January 12, February 1, and February 21, respect- 
ively. Which one of these it corresponds to must be settled by other 
means than a direct comparison. The signs given by LANDA for these 
three months all contain the same radical as No. 39, but it is impossible 
to decide with entire certainty to which it corresponds. It, however, 
most nearly resembles the sign for Zac (February 1); and it is note- 
worthy that it was precisely in this month that the greatest feast of 
TLALOC took place,* and its presence in this tablet, which relates to 
Tlaloc, is especially interesting. 
In connection with the counting of time, a reference to the bottom 
part of the chiffre 3000 of the Palenque cross tablet should be made. 
This is a knot tied up in a string or scarf; and we know this to have 
been the method of expressing the expiration and completion of a cycle 
of years. It occurs just above the symbol 3010, the chiffre for a metal. 
An examination of the original stone in the National Museum, Wash- 
ington, which is now in progress, has already convinced me that the 
methods which I have described in the preceding pages promise other 
interesting confirmations of the results I have reached. For the time,
