Much as I dislike it, I am obliged to include this story in a volume devoted to fiction: I have attempted to tell it as an absolutely true story, but until three months ago, when the indisputable proofs were placed before the British Association by Professor James Holroyd, I was regarded as an impostor. Now that the Smithsonian Institute in Washington, the Philadelphia Zoölogical Society, and the Natural History Museum of New York city, are convinced that the story is truthful and accurate in every particular, I prefer to tell it my own way. Professor Holroyd urges me to do this, although Professor Bruce Stoddard, of Columbia College, is now at work upon a pamphlet, to be published the latter part of next month, describing scientifically the extraordinary discovery which, to the shame of the United States, was first accepted and recognised in England. Now, having no technical ability concerning the affair in question, and having no knowledge of either comparative anatomy or zoölogy, I am perhaps unfitted to tell this story. But the story is true; the episode occurred under my own eyes—here, within a few hours' sail of the Battery. And as I was one of the first persons to verify what has long been a theory among scientists, and, moreover, as the result of Professor Holroyd's discovery is to be placed on exhibition in Madison Square Garden on the twentieth of next month, I have decided to tell, as simply as I am able, exactly what occurred. I first wrote out the story on April 1, 1896. The North American Review, the Popular Science Monthly, the Scientific American, Nature, Forest and Stream, and the Fossiliferous Magazine in turn rejected it; some curtly informing me that fiction had no place in their columns. When I attempted to explain that it was not fiction, the editors of these periodicals either maintained a contemptuous silence, or bluntly notified me that my literary services and opinions were not desired. But finally, when several publishers offered to take the story as fiction, I cut short all negotiations and decided to publish it myself. Where I am known at all, it is my misfortune to be known as a writer of fiction. This makes it impossible for me to receive a hearing from a scientific audience. I regret it bitterly, because now, when it is too late, I am prepared to prove certain scientific matters of interest, and to produce the proofs. In this case, however, I am fortunate, for nobody can dispute the existence of a thing when the bodily proof is exhibited as evidence.
