330 AIDS TO THE STUDY OF THE MAYA CODICES. 



on the caleudar as usual, we find the interval between 13 Ix and 3 

 Cib to be 2 months and 3 days, and. what is another necessary condi- 

 tion, the intermediate days of the column are included in this period 

 in the order in which they stand, if read upwards. The interval be- 

 tween 3 Cib, uppermost day of the tenth column, and 13 Chicchan. 

 bottom day of the ninth column, is 2 months and 9 days. The sum 

 of these two intervals is 4 months and 11 days, as it should be on the 

 supposition that the entire cohimns follow one another in regular suc- 

 cession. This prdVfs bcyund qiiestion that the columns are to be 

 read from bottom tofo/i ami that they follow one another from right 

 to left. This enables us to fix the week numbers to the intermediate 

 days and to determine the day to which the entire series is referred 

 as its starting point. The days and their numbers of the tenth and 

 ninth columns of the lower division, writing them in reverse order, 

 that is, from bottom to top, are as follows: 13 Ix; 3 Caban; 11 Chic- 

 chan; 8 Men; 3 Cib; 13 Chicchan; 3 Lamat; 11 Cib; 8 Cimi; 3 Ma- 

 nik. 



These numbers hold good throughout the series. 



Commencing with 13 Ix, the lowest day of the tenth column, lower 

 division, but first day of the series, and ending with 13 Akbal, the 

 bottom of the first column, middle series, the time embraced is 5 

 years, 1 month, day, less 4 months and 11 days — that is, 4 years, 

 14 months, 9 days (years of 360 days being understood). This is 

 easily proved by counting on the calendar 4 years, 14 months, and 9 

 days from 13 Ix, as it brings us to 13 Akbal. If we add to this time 

 2 months and 2 days — the interval between 13 Akbal and 3 Chicchan 

 (top day of first column, middle division) — we have, as the entire 

 period embraced in the series as it stands — from 13 Ix (first of the 

 series) to 3 Chicchan (the last) — 4 years, 10 months. 11 days. Add 

 to this 4 months and 11 days, in order to reach the day with which 

 the count begins, and we have as the entire period 5 years, 3 months, 

 2 days=5 years, 1 month, day-f 2 months, 2 days. If we count 

 back 4 mouths and 11 days from 13 Ix (first of the series), we reach 1 

 Kan, the day to which the series is referred as its starting point. 

 Counting forward from this date 5 years, 3 months and 2 days brings 

 us to 3 Chicchan, the last day of the series. 



It is worthy of notice that, although this series appears to be re- 

 ferred to Kan years, it is at variance with the idea of passing from one 

 to the other of the four year series, and is, moreover, based upon the 

 year of 360 days. The order in which it is to be read, which is true 

 also of some other pages, indicates that these extracts pertain to a 

 different original codex than those to which we have heretofore 

 alluded, a conclusion reached by Dr. Forstemanu soon after he com- 

 menced the study of the Dresden manuscript. 



I was for a time inclined to believe there was a break between 

 Plates 64 and 65, as there appeared to be no day columns with which
