THOMAS] PLATE 24, DRESDEN CODEX 719 
together 2,920 days—we subtract therefrom 362, the remaining days 
of the year 6 Ezanab, thus: 
Days 
8 ahaus...--- 2,880 
2 chuens. -.-- 40 

2; 920 
362 

Dividing this remainder (2,558) by 365, we find the number of years 
to be seven, with an overplus of three cays. Looking now to our 
table of years (3) and counting forward seven years from 6 Ezanab, 
we reach 13 Ben. As the next year is 1 Ezanab, we look in table 1 to 
the column headed 1 and count down this to the third day. This 
brings us to 3, and we find Ahau opposite in the Ezanab column. The 
day reached is therefore 3 Ahau, which is the day at the bottom of col- 
umn C2 in our figure 8, showing the count to be correct. 
This example, however, involves another question raised by Mr 
Goodman. It will be noticed that in column D2 of our figure the 
day place and the chuen place is each filled by an oval figure (red in 
the original) instead of the ordinary numeral symbols, and that in 
column C2 the day place is filled by a similar oval figure. In my cal- 
culation given above I have counted these as equivalent to ciphers (0), 
or nothing. Mr Goodman observes (page 64) that a number of persons 
have declared this to be a sign for naught, adding: ‘‘They were led 
into this mistake, undoubtedly, by its peculiar use and position. It is 
employed in the codices solely to designate initial periods, and in that 
position it is the equivalent of 20 in all cases except that of the chuen, 
where, like the other 20-signs, it denotes but 18.” As the example 
now under consideration affords an opportunity of testing this inter- 
pretation, we will do so. 
It is apparent from what has been shown that the correct result is 
obtained by counting these symbols as naught. If the same result 
be obtained by counting them as signs of full count—that is, 20—or as 
18 where filling the chuen place, the test fails to disclose the correct 
use of them. 
Counting the total days in each column and subtracting the sum of 
D2 from that of C2, the result is as follows:
