1881.] The Manuscript Troano, 633 
of day characters in the work, eight-ninths of which contain five 
characters each. Why this number? If, as I suppose, and as 
above illustrated, each has four dates (four different years) this 
gives to each of these columns twenty years (4 x 5 = 20), or one 
Katun, for even according to the theory of Perez, four years of 
his period were not generally counted. 
But before testing this suggestion, I wish to call attention to a 
certain regularity in the order of the days in these columns. The 
left hand column of the middle division of Plate x is composed of 
characters representing the following days (always reading from 
the top downwards) in the order here given: Oc, Cib, Ik, Lamat, 
Ix. If we turn to the list of days and count from one of these 
names to the other, we shall find in each case an interval of six 
days. The other column, same plate and division, contains the 
characters for Ahau, Cimi, Eb, Ezanab and Kan, with an interval of 
six days between each two. The column in the middle division 
of Plate vi shows an interval of five days between each two; the 
columns on Plate xvi, of twelve days; a column on Plate xxxI, 
of sixteen days; but the usual interval is either six or twelve days. 
Although the interval is usually the same throughout a column, 
there are occasional departures from this rule, for example, in the 
left hand column of the upper division of Plate x1, they are 
6, 6, 4 and 2 days. 
This fact, which is a marked characteristic of the work, is suffi- 
cient to show, beyond a reasonable doubt, that the days are here 
used simply as dates, and not for the signification of the words, as 
Brasseur supposed. 
I understand that Charency has noticed a regularity in the 
order of the days, but as I have had no opportunity of examining 
his work, I am unable to state whether it is the fact here men- 
tioned or not. 
By examining Plates xx-xxu, we see such a strong resem- 
blance between them that we are forced to believe they relate to 
One and the same subject; the left hand column of each, which 
extends the whole length of the plate, is the repetition of a single 
day character with red numerals over each character. In Plate 
Xx the character repeated is Cauac, one of the year bearers ; 
the numerals over them are as follows, and in the following order 
(reading from the top downwards): 10, I, 5, 9, 13) 4 8, 12, (?), 
7, (?), 2, 6—two of them. being obliterated.
