Numbering Quire and pages

[Wladimir D]

I can prove (without the use of chemical analysis of the ink), that label the Q20 written later than tags Q1-17, of page numbering and column of numbers on f49v.
The numbers "2" and "0" is approximately 5/8 of the height of the other digits.

   
Have not sustained proportions of numbers "1" and "2" in labels Q19 and Q20, and numbers found themselves of different heights in Q20.
