^*'^^^s] THE TIME SERIES. 17 



series with the correspoiiding (horizontal) days; that is to say, if the 

 count begins with the fifth day of the first cohimn of plate 46, the fifth 

 day of each column nuist be used successively, taking- the plates in the 

 order of numbering. This shows that the whole is one continuous 

 series, and that after the count has gone through the first cross line (or 

 top line) of the five plates it goes back to the commencement of the 

 second line, then to the third, next to the fourth, and so on until the 

 last name in the right hand column of plate 50 is reached. 



For present purposes it will be necessary to use only one of these 

 lines or series. The first or top days of the columns, commencing with 

 III Cib (or 3 Gib),* may therefore be selected. 



It is necessary now to give the names of the months and the numbers 

 attached to them exactly in the order in which they stand on the plates, 

 placing over them the corresponding first days of the columns above 

 (see table 2). The counters or intervals are also added below. It is to 

 be understood that the counter below a column indicates the interval 

 between the day over the preceding column and the day over the column 

 under which it is found. For example, 4 (months) and 10 (days) un- 

 der the second column of plate 4G indicate the interval between 3 Cib, 

 first column, and 2 Cimi, second column. 



In this table the portions of the series found on a plate are given 

 together, with the plate number over them, as "plate 40," "plate 47," 

 etc. The upper cross line of each plate is the upper line of days of the 

 day columns; the next line below this gives the months and numbers 

 of the days of the month of the first month series. These two upper 

 lines and the two lines at the bottom, consisting of months and days 

 and forming the counters or intervals, are all that will be used in the 

 explanation which follows. 



In order that the reader may observe the positions which the symbols 

 corresponding with these names and numbers occupy on the plates, a 

 facsimile of plate 50 is introduced (plate i). 



Attention should be confined to the left half of theplate. The two cross 

 lines of open dots and short lines at the bottom (colored in the original) 

 are the counters referred to. Immediately over these is the bottom line 

 of hieroglyphs corresponding with the lowest line of months on i)late 

 50 as given in table 2, viz, " [20] Xul - 10 Zac - 15 Tzec - 3 Xul." The 

 sixth cross line of hieroglyphs, on plate 50, counting from the bottom 

 uj)ward, corresponds with the second line of months as given in table 

 2, viz, " 15 Cumhu - [20] Tzec - 10 Kayab - 18 Kayab." Then, moving 

 up over the lines of black niimerals to the fifth line of hieroglyiihs 

 above them, which line stands immediately below the day columns, we 

 find the symbols representing the upper line of months in the table, 

 viz, " 10 Kankin - [20] Cumhu - 5 Mac - 13 Mac." 



* For convenience the Arabic numerals will be used thronghout this jtaner, except 

 where necessity requires the introduction of Roman notation.
