the tonalamatl (see p. 253), and this is found to be the case, since 

 the day sign Cimi is the second in the column of day signs to the left. 

 Compare this form ^^dth figure 17, r, j. The day recorded is therefore 

 1 Cimi. 



The first division of the tonalamatl under discussion is subdivided, 

 therefore, into three parts, the first part commencing wdth the day 

 1 Ix, containing 13 days; the second commencing mth the day 1 

 Manik, containing 26 days; and- the third commencing with the day 

 1 Ben, containing 13 days. 



The second division of the tonalamatl commences with the day 

 1 Cimi, as we have seen above, and adding to this the first black 

 number, 13, as before, according to rules 2 and 3 (p. 253), the begin- 

 ning day of the next subdivision will be found to be 1 Cauac. Of 

 this, however, only the 1 is declared (see to the right of the black 13). 

 Adding the next black number, 26, to this da}^, according to the above 

 rules the begmnmg day of the next subdivision will be fomid to be 

 1 Chiccliaii. Of this, however, the 1 again is the only part declared. 

 Addmg the next and last black number, 13, to this day, 1 Chicchan, 

 according to the rules just mentioned the beginning day of the next, 

 or third, main division will be found to be 1 Eznab. Compare the 

 third day sign m the column of day signs with the form for Eznab in 

 figure 17, z, a'. The second division of tliis tonalamatl contains, 

 therefore, three parts: The first, commencing mth the day 1 Cimi, 

 containing 13 days; the second, commencing with the day 1 Cauac, 

 containing 26 days; and the third, commencing with the day 1 

 Chicchan, containing 13 days. 



Similarly the third division, commencing with the day 1 Eznab, 

 could be shown to have three parts, of 13, 26, and 13 days each, com- 

 mencing with the day 1 Eznab, 1 Chuen, and 1 Caban, respectively. 

 It could be shown, also, that the fourth division commenced with tho 

 day 1 Oc (compare the fourth sign in the column of day signs with 

 figure 17, o), and, further, that it had three subdivisions containing 

 13, 26, and 13 days each, commencing with the days 1 Oc, 1 Akbal, 

 and 1 Muluc, respectively. Finally, the fifth and last division of the 

 tonalamatl will commence wdth the day 1 Ik. Compare the last day 

 sign in the column of day signs *\\ith figure 17, c, d; and its three 

 subdivisions of 13, 26, and 13 days each with the days 1 Ik, 1 Men, 

 and 1 Imix, respectively. The student will note also that when the 

 last black number, 13, has been added to the begmning day of the 

 last subdivision of the last division, the day reached will be 1 Ix, the 

 day with \vhich the tonalamatl commenced. This period is con- 

 tinuous, therefore, reentering itself immediately on its conclusion and 

 commencing anew.
