bit (tochtli) see, in plate 13, the animal with 

 large ears figured in the eighth compartment, 

 reckoning from the bottom on the right ; plate 

 23, the third compartment at the bottom on the 

 left ; and more especially plate 27, No. 1, the 

 eighth compartment. For cane (acatl), flint 

 (tecpatlj, and house ( calli), see, on the circular 

 stone represented plate 23, the fifth, tenth, and 

 fifteenth compartments, which follow that of the 

 rabbit, from left to right. We shall easily re- 

 cognise the same forms in plate 27, No. 1, in 

 the compartments thirteen, eighteen, and three, 

 reckoning in the same row from right to left, 

 and beginning with the lower row. The sign of 

 flint is also seen in plate 13, behind the figure in 

 the attitude of adoration. On this same plate 

 the calli is represented by the entire figure of a 

 house, in which are seen the door, and a very 

 elevated roof. 



Let us at present imagine the cycle, or the 

 half old age, divided into four tlalpilli, each of 

 thirteen years ; and the four signs rabbit, cane, 

 flint, and house, added in a periodical series to 

 the fifty-two years contained in a cycle, we shall 

 find, that two indie tions cannot begin by the 

 same sign ; that the sign placed at the head of 

 an indiction must necessarily terminate it, and 

 that the same sign cannot belong to the same 

 number. The following is the table of the 

 Mexican cycle, called ligature or xiuhmolpilli.
