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.
