Applying rule 4 (p. 253) to tliis tonalamatl, we have: 10 X 26 = 260, 

 the exact number of days in a tonalamatl. 



The tonalamatl which appears in the middle part on plate 28 — that 

 is, Dresden 15b — extends over on page 16b, where there is a black 13 

 and a red 1. The student will have little difficulty in reaching the 

 result which follows: The last day sign is the same as the first, and 

 consequently this tonalamatl is divided into four, instead of five, 

 divisions :

Applying rule 4 (p. 253) to this tonalamatl, we have: 4x65 = 260, 

 the exact number of days in a tonalamatl. The tonalamatls hereto- 

 fore presented have all been taken from the Dresden Codex. The 

 followong examples, however, have been selected from tonalamatls in 

 the Codex Tro-Cortesianus. The student will note that the workman- 

 ship in the latter manuscript is far inferior to that in the Dresden 

 Codex. This is particularly true with respect to the execution of 

 the glyphs. 



The fu-st tonalamatl figured from the Codex Tro-Cortesianus (see 

 pi. 29) extends across the middle part of two pages (Tro-Cor. 10b, 

 lib). The four day signs at the left mdicate that it is divided into 

 four divisions, of which the first begins with the day 13 Ik.' Adding 

 to this the first black number 9, the day 9 Chuen is reached, and pro- 

 ceeding in this manner the tonalamatl may be outlined as follows :
