An examination of the plates will show that Dr. Foerstemann has filled out
the following obliterated or wanting day numbers, to wit, the first of
the upper line of Plate 46, the fourth of the upper line of Plate 47, and
the second of the middle line and first of the lower line of Plate 50. He
has also ventured to change the first day number of the lower line of
Plate 46 from 16 to 14. Where the number 20 is found in his list there is
no corresponding number in the codex, the month symbol only being given.
It is evident he has proceeded in these cases upon the theory that the
absence of a number indicated that the month was completed. Although
probably correct in this conclusion, the question will arise, Does the
symbol in such cases denote the _month completed_ or the _month reached?_

The intervals between these dates are as follows, the left hand column
being those between the first and second columns of Foerstemann's list
(our Table IV), the second column those between the second and third
columns of his list, the third column those between the third and fourth
columns of his list, and the fourth column those between the last date of
one plate and the first of the next:
