NUMEKAL VALUE OF THE MONTH SYMBOLS. 71 



5. MAC.-100 days. 



The superfix in the first glyph is one of the signs used interchangeably for 20, hut 

 the head is unrecognizable. The second glyph, from the codices, enlightens us 

 respecting its meaning, however. It is one of the conventional symbols for the closed 

 hand, signifying 5, and is multiplied by the most unmistakable of the 20-signs — 

 5x20=100. 



6. KANKIN.-120 days. 



The cornstalk symbol in both these glyphs is qualified by a 10-sign ; hence the 

 former must be an equivalent of 12 — 12x10=120. The kin character in the first 

 glyph does not appear to affect the value, only its name. The kankin symbol is one 

 of the signs employed to denote that a reckoning is by days, but, very consistently, its 

 use is confined to computations by 120-day periods. 



7. MUAN — 140 days. 



This glyph is inexplicable, further than that the wing in the first one should denote 

 20, in which event the bird's head must be equivalent to 7 ; but the character is drawn 

 so differently at different times that it is not safe to assume anything concerning it.
