script. These dates and their intervals certainly have some connection 

 with the numbers placed within the serpents, but I do not yet venture 

 to express an opinion in regard to them. 



Pages 62 and 63 contain, the former in the last two columns, the 

 latter in the first two, a very fine and lucid combination of large 

 numbers, of encircled numbers below them, and of dates. Although 

 I have already considered the first, the numbers, I transcribe here the 

 entire passage: 



1,272,931 1,272,544 



III 2; 18, 3d month. XIII 20; 11, 1st month. 



(456) (121) 



IV 17; 8, 18th month. IV 17; 8, 18th month. 



1,284,220 1,268,540 



III 2; 13, 14th month. XIII 20; 6, 18th month. 



(235) (17) 



IV 17; 8, 18th month. IV 17; 8, 18th month. 



I have allowed myself a slight conjecture in regard to the date 

 at the top in the second group only. I read the manuscript's 15, 1st 

 month; 11, 1st month, assuming that the writer made a line instead 

 of a dot. As Ave consider the differences between the upper dates 

 and the normal date that is set down below, it should be mentioned 

 that the former indicate the years 4 Ix, 4 Ix, 5 Ix, and 7 Cauac, and 

 the latter, as already observed, the year 9 Ix. The intervals are, 

 therefore, as follow : 



44 years+295 days=:l(),355 = (J2x26U+235 days 



44 years+3.37 days=i 16,397=63X260+ 17 days 



4 years+ 75 days=: 1,.535= 5x2(50+235 days 



15 years+ 2 days= 5,477=21x260+ 17 days 



The days in excess of the multiples of 260 are, therefore, equal to 

 the encircled numbers in the third and fourth groups. 



The explanation of these groups is written above them, unfor- 

 tunately in characters as yet undeciphered. But there is such a small 

 number of different signs among these twenty-eight, owing to the fre- 

 ({uent repetition of some, that I think a complete comprehension will 

 be achieved here, as well as on page 24, Very soon, especially as 

 several of the characters are among those most frequently used in 

 the manuscript. 



In the third column of page 63 there is still to be regarded a doubt- 

 ful date at the top, and a normal one at the bottom. 



Page 69 has the normal date in the middle of the two middle 

 columns, but at the bottom the date IX 1 ; 12, 17th month, which is re- 

 peated at the top of the fifth and sixth columns. It is the same 

 which we have already met with three times on pages 61 and 62. Fur- 

 thermore, on the right, at the bottom, page 69 gives the days IV 9 

 and IX 11, which are very important for the last pages of the manu-
