THE ARCHAIC MAYA INSCRIPTIONS. 



2. YAX.-40 days. 



The combination here is simply that of the 10-day symbol with the yax sign for 4 — 

 10x4 = 40. The value of the yax sign is one of the best established in the whole 

 group of numeral characters. 



3. ZAC— 60 days. 



Here we are compelled to reverse the process, and reason from its association with 

 the 10-day sign that the superfix must have the value of 6 — 10x6 = 60. 



4. CEH.— 80 days. Qw^ 



Here, again, the value of the superfix must be deduced from its connection— 

 10x8 = 80 — the character occurring in no other place where its value is determinable.
