series extending to the left of the
day column. Is this an exceptional case? I am inclined to believe it is,
for the following reasons:

Taking the 4, V over the bird as the first pair of the series, we have
I + 4 = V, which is so far correct; after this follows the pair in the
lower left hand corner, 8, XIII, as V + 8 = XIII. It is probable that the
obliterated pair in the upper left hand corner followed next, then the
pair in the upper right hand corner, and last the partly obliterated one
in the lower right hand corner. In this case the obliterated pair in the
upper left hand corner should be 11, XI, as XIII + 11 - 13 = XI, and XI +
15 - 13 = XIII, and XIII + 14 - 13 - 13 = I, which makes the terminal red
number of the series the same as that over the day column. This
restoration requires no change of any of the numbers which can be
distinctly read. By adding together the black numbers 4, 8, 11, 15, 14,
the sum is found to be 52, precisely the interval between the days of the
column. These facts are sufficient to render it more than probable that
the restoration and the order as here given are correct. The series as
thus given, including the number over the day column, is: I; 4, V; 8,
XIII; 11, XI; 15, XIII; 14, I.

This is repeated, because on turning to Dr. Foerstemann's comment on this
series I find that he has restored and amended it so as to read thus: I;
10, XI; 4, V; 15, XIII; 9, XIII; 14, I; and he remarks that all would be
plain sailing if, for the V before and the XIII after 15, we could read
II and IV. This is true, but these numbers are too distinct to justify
such change; moreover his "9" is not to be found on the page; it is true
that the three dots over the line are not exactly spaced, but there are
no indications of a fourth; the number is 8 and should, I think, be so
read. His 10 is the obliterated black numeral; of course the value
attributed to it depends upon the order given to the series. The
fragments remaining of the red number of this pair I think warrant his
making it XI.

Plates 46, 47, 48, 49, and 50 are peculiar and seemingly have no direct
relation to any other part of the codex. In the upper left hand corner of
each are four day columns, all more or less injured, but each column
evidently contained, originally, thirteen days, or, more correctly
speaking, the symbol for one day repeated thirteen times. In every case
the day in the first (left hand) column and that in the third column ar
