The Manuscript should have set down under these numbers the day IX Ix twice
and IV Eb twice, from which days the numbers in question must be computed;
but here the two errors already mentioned were made. 111,554 - 101,812 is
9742, the very same number which we shall afterward find as the difference
of the serpent numbers on page 69.
83,474 - 34,732 = 48,742. If 9472 be subtracted from this, the remainder is
exactly 39,000 = 150 Tonalamatls = 50 revolutions of Mars. I have already
found this number on page 31a, and also the double of it, 78,000, on page
24, and this I found by using 68,900 + 9100 for my computation.
111,554 - 83,474 = 28,080, _i.e._, exactly the double of the important
14,040, which is recorded on page 73.
101,812 - 34,732 = 67,080, _i.e._, = 258 Tonalamatls or 86 revolutions of
Mars.
111,554 - 34,732 = 76,822; if 122, the interval from IV Eb to IX Ix be
subtracted from this, the remainder is 76,700 = 295 Tonalamatls.
101,812 - 83,474 = 18,338; if 138, the interval from IX Ix to IV Eb, be
subtracted from 18,338, the remainder is 18,200 = 70 Tonalamatls = 50
ritual years of 364 days each, _i.e._, exactly the double of the 9100
specified on page 24.
