words ata, bosa, mica, and their graphic signs, 

 arranged in three periodical series, were made 

 use of to denote the thirty days of a lunation ; so

 weeks and the siina, have no common divisor, 

 and can coincide only after three times ten 

 days. According to the following table, in 

 which the small festivals are distinguished by 

 italic characters, cuhupqua (two ears) falls in

 the period of the conjunction ; mica (two eyes 

 open) denotes the first quarter ; and ubchihka 

 (an ear) the full Moon. The relation we here 

 find between the thing and the hieroglyphic, be- 

 tween the phases of the Moon and the signs of 

 the lunar days, evidently prove, that these signs,
