"It is, it is!" exclaimed Passe-partout. "You have made a mistake of one day. We arrived twenty-four hours before our time, but we have only ten minutes left now."
As he spoke Passe-partout fairly dragged his master out of his chair.
Phileas Fogg, thus seized, had no choice. He rushed downstairs, jumped into a cab, promised the driver a hundred pounds, ran over two dogs, came into collision with five cabs, and reached the Reform Club at 8.45.
So Phileas Fogg had accomplished the journey round the world in eighty days, and had won his bet of twenty thousand pounds.
Now how was it that such a methodical man could have made a mistake of a day? How could he imagine that he had got back on Saturday the 21st when it was really Friday the 20th, seventy-nine days after his departure?
The reason is very simple.
Phileas Fogg had unconsciously gained a day, simply because he journeyed always eastward, whereas, had he journeyed westward, he would have lost a day.
In fact, travelling towards the east, he had gone towards the south, and consequently the days got shorter as many times four minutes as he crossed degrees in that direction. There are three hundred and sixty degrees, and these multiplied by four minutes give exactly twenty-four hours; that is the day Fogg gained. In other words, while Phileas Fogg, going east, saw the sun pass the meridian eighty times, his friends in London only saw it seventy-nine times, and that is why on that day, which was Saturday, and not Sunday, as Mr. Fogg thought, they expected him at the Reform Club.
Passe-partout's wonderful watch, which had always kept London time, would have confirmed this had it only marked the days as well as the hours and minutes.
So Phileas Fogg had won his twenty thousand pounds, but as he had expended nearly nineteen thousand pounds, his gain was small. However, he had not bet for money. He actually divided the thousand pounds that remained between honest Passe-partout and the unfortunate Fix, against whom he bore no malice. But from Passe-partout's share he deducted, on principle, the cost of the gas which had been burning for one thousand nine hundred and twenty hours. That same evening Mr. Fogg, as tranquilly as ever, said to Aouda, "Is the prospect of our marriage still agreeable to you?"
