sole living inhabitant of Earth to-day: there are others, though mostly of the same name, whose ancestors would somewhat swell the totals. In mercy to the reader I have ignored them, one man being sufficient for my purpose.
Must not John Smith have had all those ancestors? Certainly. Could all those ancestors of John Smith have existed? Certainly not. Have I not, therefore, as I promised to do, conducted the reader against "a proposition which is at the same time unquestionable and impossible " — a, statement "which must be true, yet can not be true"? According to the best of my belief he is there. And there I leave him. Any gentleman not content to remain there with his face to the wall is at liberty to go over it or through it if he can. Doubtless the world will be delighted to hear him expose the fallacy of my reasoning and the falsehood of my figures. And I shall be pleased myself.
1894.
