Von Kempelen and His Discovery

Von Kempelen and his Discovery (1849). First published in The Flag of Our Union, April 14, 1849. Created as a hoax during the California Gold Rush.
After the very minute and elaborate paper by Arago, to say nothing of the summary in 'Silliman's Journal,' with the detailed statement just published by Lieutenant Maury, it will not be supposed, of course, that in offering a few hurried remarks in reference to Von Kempelen's discovery, I have any design to look at the subject in a scientific point of view. My object is simply, in the first place, to say a few words of Von Kempelen himself (with whom, some years ago, I had the honor of a slight personal acquaintance), since everything which concerns him must necessarily, at this moment, be of interest; and, in the second place, to look in a general way, and speculatively, at the results of the discovery.
