Page 297, footnote 44: "decisons" to "decisions".
Page 310: "you mean cant. No, I don't." changed to "you mean cant."¶"No, I don't." (Two quotation marks, and a paragraph break inserted).
Page 315, footnote 22: "spokne" to "spoken".
Page 331: "Prounciation" to "Pronunciation".
Page 340: "anemia, 242, 262" to "anemia, 242, 263". Also, in "anti-fogmatic, IR", "IR" to "84". Note that the "I" and "R" keys are close to the "8" and "4" keys on a qwertyop keyboard.
Page 341: "Beaver Moon, 4wn" changed to "Beaver Moon, 42n". This is an educated guess—but "Beaver and Hunting" is mentioned on page 42, footnote 9, as one of the Indian months (moons?). Also note that the "2" key is near the "w" key on a qwertyop keyboard, and there are six instances of this or similar (probable) mistake in the index—see below and just above.
Page 347: "discipine, 251" to "discipline, 251".
Page 348: "encylopaedia, 243" to "encyclopaedia, 243". Also "eychre" to "euchre".

Page 354: in "lot, 31, 51, 52, 5wn", "5wn" to "52n", referencing footnote 28 anchored on page 52, which discusses "lott".
