The letter says the large Danish dog will arrive on the 15th of February. In chapter 3 the dog arrives on the 15th of March "as the captain's letter had said." Other versions have the same inconsistency.

In the discussion of steamers, the doctor observes of the Fox that MacClintock "succeeded in making his way more easily and more directly than all his successors." Other translations say "predecessors" which makes more sense.

Meridian of Greenwich.

On April 14 the longitude given is 22 degrees 37 minutes. Other versions give 22 degrees 58 minutes. Other versions agree that the latitude is 51 degrees – which hardly seems possible for a ship leaving Ireland at nearly 56 degrees latitude and sailing northwest. 57 degrees seems more likely. A few days later the latitude is further confused during the discussion of iceberg sightings. The doctor states that they are two degrees further north than a sighting of icebergs occurring at 42 degrees latitude, apparently confusing the Forward's latitude with that of the Ann Poole

A peculiar and brilliant color of the air above a large expanse of ice.

In the remembrance of Parry's expedition into Lancaster Sound, mention is made of the prize for crossing a meridian at higher than the seventy-seventh parallel. Here the specific meridian is left out, which is not very informative. In the French version, it is the 170th meridian, which is clearly wrong. The Ward and Lock translation changes it to the 117th meridian. Historically, the prize was for the 110th meridian

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.

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

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.

Although "the Governor was born on the island of Disco, and he has never left the place," the landing party meets him at Upernavik which is well north of the island of Disco

Sea-birds common in these latitudes.

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

Names of several English explorers have been garbled in this translation:

"Stuart" = Charles Sturt

"McDougall Stuart" = John McDouall Stuart

"Wells" = William John Wills

"Havnoan" = ?? – Haouran (French version) is a place in Syria
