s in ms., should be 4.

[317-1] The third symbol in the last day column of Plate 51_b_ is Been in
the codex; but this is an evident mistake, as shown by the order of the
days, since Ahau, which has been substituted above, always follows Cauac.
This may be seen by reference to the middle column of 57_b_.

[319-1] This is one of the exceptional cases.

[321-1] Second exception.

[321-2] Third exception.

[323-1] One line has been omitted in the numeral symbol.

[323-2] Here we have again the added day.

[324-1] The 8 at this point in the codex is an evident error.

[324-2] Here is also an error in the original, this being 10.

[324-3] The symbols require an additional day here.

[324-4] The 8 in the year line in the original is a manifest error, as 6
precedes and 7 follows.

[324-5] The 18 in the day line at this point is also an error, as the
interval between 2 Muluc and 10 Cimi is 8 months and 17 days. Moreover,
the next day number being 16 requires this to be 19.

[325-1] The counters in the original at this point are certainly wrong,
for here should be 7 months and 8 days, whereas the symbols are those for
8 months and 17 days.

[325-2] Here we have again the additional day.

[325-3] Added to show connection with the lower series.

[333-1] Codex has 19, which is equivalent to 1 year and 1 month.

[337-1] While reading the final proof I fortunately discovered what may
prove to be the correct explanation of the numbers in the loops.

At the commencement of the series on Plate 71 and at its close on Plate
73 we observe the symbol of the day, 9 Ix. Starting from this date and
counting forward on the calendar two months and fourteen days, we reach
11 Lamat. This gives the number in the first loop of the series. Two
months and fourteen days more bring us to 13 Ik, the number in the second
loop; two months and fourteen days to 2 Cib, the number in the third
loop, and so on to the end. It is therefore probable that the numerals in
the loops indicate the week numbers of the days, though these are usually
expressed in red symbols.

[338-1] The 7 in the twelfth column is an error; it should be 8, as an
inspection shows the place of the missing dot. The additions make it
clear that the numbers of the second line refer to months, those of the
line below them to days, and those of the line above to years. The series
is, therefore, apparently complete without the numbers inclosed in the
loops.
