17) The first words of page 147 repeat the last words of page 146. Pages 147-236 (Ts-227a,147 "[er]finden, das nie von jemandem gespielt wird.-" until Ts-227a,236 "handle von Greifbarem und Ungreifbarem.– Aber findest du") are taken from the PI "Zwischenversion", manifested by Ts-242. Before the change of the page numbering, Ts-227a,147 was page "145", and Ts-227a,236 was page "194" (of the "Zwischenversion").

18) There is an arrow pointing left, probably indicating that the mistaken indentation shall be canceled.

19) Insertion from page 192a (handwritten note).
