* Early scam artist ?
* Non steam Motor

Page 4 has a fascinating article headed: "A Wonderful Discovery ! " A New Motor ! " "The Days of Steam Probably Numbered". This is a lengthy article (takes over 3 columns) on inventory John E. W. Keely who claimed to have discovered a new mode of power originally described as "vaporic" or "etheric" force by which he produced "interatomic ether" from water and air. Despite numerous requests from the stockholders of the Keely Motor Company, he consistently refused to reveal to them the principles on which his motor operated & also repeatedly refused demands to produce a marketable product by claiming that he needed to perform more experiments. He secured substantial investments from many people, including John Jacob Astor. See the hyperlink for the elaborate fraud he managed to maintain for over 26 years.
Eight pages, nice condition.
