Thank you redon! Mostly dry stuff but a few interesting things to note, particularly the numbers that might be page numbers. If that's what they are then Chapter 1 might have originally been even longer. I can't read a few things because I'm not familiar with the terms and therefore can't guess the kanji but maybe someone can help
