Li this manner all of the begmning days could be worked out as 

 below :

The application of rule 4 (p. 253) to this tonalamatl gives: 

 5 X 52 = 260, the exact number of days in a tonalamatl. As previously 

 explained, the second column of day signs belongs to another tonala- 

 matl, which, however, utilized the same red 8 as the first and the 

 same black 27 and 25 as the first. The outline of this tonalamatl, 

 which began with the day 8 Oc, follows:

The application of rule 4 (p. 253) to this tonalamatl gives: 

 5 X 52 = 260, the exact number of days in a tonalamatl. It is inter- 

 esting to note that the above tonalamatl, beginning with the day 

 8 Oc, commenced just 130 days later than the first tonalamatl, which 

 began with the xlay 8 Ahau. In other words, the first of the two 

 tonalamatls m Dresden 12a wag just half completed when the second 

 one commenced, and the second half of the first tonalamatl began 

 with the same day as the first half of the second tonalamatl, and 

 vice versa. 



The tonalamatl in plate 28, upper division, is from Dresden loa, 

 and is uiteresting because it illustrates how certain missing parts 

 may be filled in. The first red number is missing and we can only 

 say that this tonalamatl began with some day Ahau. However, 

 adding the first black number, 34, to this day ? Ahau, the day reached 

 A\ill be 13 Ix, of which only 13 is recorded. Since 13 Ix was reached 

 by coimting 34 forward from the day mth which the coimt must have 

 started, by counting back 34 from 13 Ix the starting pohit will be
