“ Spanish navigators reckoned Longitude East 360 degrees from the meridian of the Isle of Ferro. For the sake of perspicuity before a modern audience, the more recent meridian of Madrid was substituted. The custom of dropping a day at some arbitrary point in crossing the Pacific westerly, I need not say, remains unaffected by any change of meridian. ”
