Passepartout was ignorant that, if the face of his watch had been divided into twenty-four hours, like the Italian clocks, he would have no reason for exultation; for the hands of his watch would then, instead of as now indicating nine o’clock in the morning, indicate nine o’clock in the evening, that is, the twenty-first hour after midnight precisely the difference between London time and that of the one hundred and eightieth meridian. But if Fix had been able to explain this purely physical effect, Passepartout would not have admitted, even if he had comprehended it. Moreover, if the detective had been on board at that moment, Passepartout would have joined issue with him on a quite different subject, and in an entirely different manner.
