This, however, is no other than the glyph of god C, the representa- 

 tive of the north and tlie night. 



The six small groups on this plate are as follow : 



A 7 to B 9 : 1, 13. ( ?), 30, 10, 9, 29. 



F 9 to E 11: 16, 9, 29. 1. 



KG to 7: 1. 4, 30. 



B 4 Q 4 : 1, 30. 



R 7 to 8: 1. 13, 30. 



T 10 to 11: 1, 13, 30. 



The last two identical groups have still further reference to one 

 another inasmuch as each is directly preceded by three glyphs wdiich 

 correspond to one another; S 1, S 2, and S 3, namely, are like U G, 

 U 7, and U 8, though the int/ervening characters in columns R and T 

 are very different in both places. 



On plate lxii the formation of such groups or formulas would be 

 hardly appropriate, for this plate is almost wholly filled with dates 

 and i^eriods, as I haA'e shown to be the case in the familiar Cross 

 inscription. A few remarks relative to the dates and periods may be 

 in place here. 



We are first struck l)y the fact that the beginning of the page con- 

 tains four dates without a statement of the periods intervening : 



B8 A9: X 17; 8, 7 (1 Ix). 

 C 1 D 1: VIII 17; 8, 2 (8 Ix). 

 O 7 D 7 : VII 17 ; 18, 2 (10 Kan). 

 C 11 D 11: X 17; 13, 7 (9 Muliic). 



The day 17, therefore, occurs four times. This is the most impor- 

 tant and most frequently employed of all the days, but it occuj^ies a 

 varying position in the weeks and years. The interval from the first 

 to the second is computed at 7,200, from the second to the third at 

 740, from the third to the fourth at 9,220 days. The number 7,200 

 represents, of course, the familiar period of 20X3(>0, but what are 

 the other two intervals? 



A few of the dates on this plate correspond to the intervening 

 period : 



Q .5: X 17; there is no 8. 7 (1 Ix) with this. 



P o Q 5: ()+r,x20+3x3()0=l,20(i=4x2<!0-rl<)(;=3X3(J5+lll. 



P 7: VII 3; 19. 12 (4 Muluc). 



In f.ut. X 17 t') VII 3=1C.(;: 8. 7 to 19, 12:^111. 



Again, 



11 c. S r, : VII. 14: l.'>. 1 (7 Kan). 



R 7 to K 8: 1 +(;x2()+7x3(;o+2x7.2(»0=17.041 =<;.~.X2()04-141=4r.x 



3G.5+2.'^1. 

 R 11 S 11: V 1.5: G. 14 (1 Ix). 

 R 6 should be read VIII rather than VII. Then, VIII 14 to V 15=101 



and 15, 1 to 6, 14=251.
