Applying rule 4 (p. 253) to this tonalamatl, we have: 5x52 = 260, 

 the exact number of days in a tonalamatl. The next tonalamatl on 

 this page (see third division in pi. 29, that is, Tro-Cor., 102c) is inter- 

 esting chiefly because of the fact that the pictures which went with 

 the third and fourth parts of the five divisions are omitted for want 

 of space. The outlme of this tonalamatl follows: 



1st part, 17 days, beginning 

 with day 



2d part, 13 days, begianiag 

 with day 



3d part, 10 days, beginning 

 with day 



4th part, 12 days, begin- 

 ning with day 



Total number of days 



4 Lamat 



8 Chicchan 

 8 Eznab 



5 Lamat 



52 



Applying rule 4 (p. 253) to this tonalamatl, we have: 5 X 52 = 260, 

 the exact number of days in a tonalamatl. The last tonalamatl in 

 plate 29, Tro-Cor., 102d, commences with the same day, 4 Ahau, as 

 the preceding tonalamatl and, like it, has five divisions, each of which 

 begins with the same day as the corresponding division in the tona- 

 lamatl just given, 4 Ahau, 4 Eb, 4 Kan, 4 Cib, and 4 lamat. Tro-Cor. 

 102d differs from Tro-Cor. 102c in the number and length of the parts 

 into which its divisions are divided. 



Adding the first black number, 29, to the beginning day, 4 Ahau, 

 the day reached will be 7 Muluc, of which only the 7 appears in the 

 text. Adding to this the next black number, 24, the da}-^ reached 

 will be 5 Ben. An examination of the text shows, however, that the 

 day actually recorded is 4 Eb, the last red number with the second 

 day sign. This latter day is just the day before 5 Ben, and since the 

 sum of the black numbers in this case does not equal any factor of 

 260 (29+24 = 53), and since changing the last black number from 

 24 to 23 would make the sum of the black numbers equal to a factor 

 of 260 (29+23 = 52), and would bring the count to 4 Eb, the day 

 actually recorded, we are justified in assuming that there is an error 

 in our original text, and that 23 should have been \VTitten here instead 

 of 24. The outline of this tonalamatl, corrected as suggested, follows:
