treated, to a year of 364 days, which is divided into four quarters 

 dedicated .o individual Bacabs, each comprising 7 weeks of 13 days 

 each. But we are not dealing here with a single year; but, in pro- 

 portion to the space occupied by the groups, with a period of 

 13X69 ==897 days; that is, with two such years and 13 weeks. Let 

 us try to prove this. 



First of all, in group 37« appears a human figure stretching both 

 jirms upward (I) ; this is repeated in group 65c// that is to say, 

 twenty-eight places farther on, so that just one year (13X28^364) 

 lies between them. We see the same human figure, more complete, 

 with its glyph, on page 365/ a bird issues from its head, holding a 

 fish in its beak. The preceding year should begin in group 9a, but 

 the glyph there is nearly destroyed. 



But now in that year, between groups 37 to 65, I can also point out 

 the four Bacabs, which, however, as in the passage on pages 71 to 73, 

 do not coincide with the beginning and end of the year. For the 

 signs 39, 46, 53, 60 {h in every case), show the Bacab sign previously 

 found (m), in the last three identical, in the first at least similar, 

 always after an interval of 7 weeks. We should expect to find the 

 same sign in the preceding year in groups 4, 11, 18, 25, and 32, but I 

 can not point it out there, although I will add that 25« shows at least 

 the glyph which was combined with the Bacab sign on page 71. 



If we look at the groups which immediately precede these Bacab 

 groups, we see in 38, 52, and 58 (which, according to what has been 

 said above, should really be 59), in the lower part heads like those 

 of birds, resembling the Bacab sign, which all resemble each other. 

 A similar head might be expected in group 45, but instead we find a 

 Moan head, which is likewise a bird's head. Thus we again see 

 intervals of 7 weeks between each. 



In all of the eight groups mentioned, 38 and 39, 45 and 46, 52 and 

 53, 59 (nominally 58, as before mentioned) and 60, we always find 

 the glyph Imix as the first, or at least a part of the first, sign, which 

 is another confirmation of their general connection. 



But these are not the only instances of a repetition after seven 

 groups. In 42a and 495 we see the same sun sign represented be- 

 tween light and darkness. In 17 and 24 the same head occurs as the 

 lower sign ; also, it is true, in 15, 29, 40, 44, but here, too, 15 and 29 

 agree after an interval of 2X7 groups. Groups 15a and 36a agree 

 after 3X7=21 groups; after a similar interval 10a and 31a show 

 the same crouching person ; but so, also, do 20a and 30a. 



If, according to my proposition, 55 and 54 are transposed, then the 

 two signs of 33 and 34 will exactly corresj^ond to these after 3X7=21 

 weeks; so, too, will 35 and 56 agree, if, as I have also proposed, 56 is 

 put in the place of 57.
