[Chapter 8]: On Saturday, the temperature is stated to have fallen to 8 degrees above zero. The French and Routledge translation state 8 degrees below zero. This makes more sense since the previous temperature cited, from which it had fallen, was 6 degrees above zero.
[Chapter 8]: The block of ice which turns upside down is stated to be 800 feet high. This appears to be a mistranslation of the French; other translations have it as at least a hundred feet high.
[Chapter 9]: According to this translation, the Forward crosses the 62nd parallel on May 5. This is clearly incorrect since the ship is north of its May 1 latitude of 68 degrees. Other versions have this as the 72nd parallel. This agrees with the accompanying map.

[Chapter 12]: The captain declares their latitude to be at 72 degrees when they are actually at [74 degrees]. The promise of 1000 pounds for each degree beyond 72 is continued throughout the book.
