Filby became pensive. “Clearly,” the Time Traveller proceeded, “any real body must have extension in four directions: it must have Length, Breadth, Thickness, and—Duration. But through a natural infirmity of the flesh, which I will explain to you in a moment, we incline to overlook this fact. There are really four dimensions, three which we call the three planes of Space, and a fourth, Time. There is, however, a tendency to draw an unreal distinction between the former three dimensions and the latter, because it happens that our consciousness moves intermittently in one direction along the latter from the beginning to the end of our lives.”

This Inspector, when I first knew him, was a man of fourscore years, or thereabouts, and certainly one of the most wonderful specimens of winter-green that you would be likely to discover in a lifetime’s search. With his florid cheek, his compact figure, smartly arrayed in a bright-buttoned blue coat, his brisk and vigorous step, and his hale and hearty aspect, altogether he seemed—not young, indeed—but a kind of new contrivance of Mother Nature in the shape of man, whom age and infirmity had no business to touch. His voice and laugh, which perpetually re-echoed through the Custom-House, had nothing of the tremulous quaver and cackle of an old man’s utterance; they came strutting out of his lungs, like the crow of a cock, or the blast of a clarion.
