SERIES ON PLATES 46 TO 50. 29;) 



In considering these horizontal lines it is to be understood tliat the 

 series runs thi'ougli the five pages, 40-5(1. 



Let us ijroceed upon the supposition that the figures of the lowest 

 of the three lines denote days of the month, the numbers of the middle 

 line months, and those of the upper line years. As already shown, 

 the interval between 8 Cib and 7 Cimi is 4 months and 10 days; add- 

 ing 4 months and 10 days to 11 months and 16 days (bearing in mind 

 that 20 days make a month and 18 months a year), the sum is found 

 to be 16 months and 6 days, precisely the figures under 7 Cimi. As 

 already ascertained, the interval between 7 Cimi and 10 Cib is 12 

 months and 10 days; this added to 10 months and 6 days gives 1 year, 

 10 months, 16 days, precisely the figures under 10 Cib. The interval 

 between 10 Cib and 5 Kan is 8 days; this added to the 1 year, 10 months, 

 and 10 days gives 1 year, 11 months, and 4 days, the figures imder 5 

 Kan. The interval between 5 Kan and 7 Ahau is 11 months, 10 days, 

 wliich, added to the preceding, gives 2 years, 5 months, o (la\-. agree- 

 ing with the figui'es under 7 Ahau, if the symbol rcpi-i'Sfutcl liy 

 signifies nought. That this rule holds good thi-oughuut thf t^ntire 

 series, by making one correction, is shown by the following additions:
