SCIENTIFIC AMERICAN, New York, October 12, 1907  The frontpage features two almost comical photos of an early attempt at an airplane, called: "The Gammeter Orthopter". Another caption notes: "A New Beating-Wing Flying Machine, a Competitor for the Scientific American Trophy." Interesting that this bizarre concept was a consideration four years after the Wright brothers' flight.
Other articles are: War Cars, Ancient and Modern; How to Prevent Failure in Concrete Construction; Blood Pressure and Mental Conditions; and other articles and advertisements. This is a full issue and in good condition. See photos for full details.
