Colored lithograph of the "Aerostat" flying machine aloft over a field with a river and city in the background. A diagram of the machine is below the scene with a scale and captions. This hand-operated ornithopter was designed, but apparently neither built nor tested by W. Miller Text to the right of the diagram has a more detailed description of the machine and how it is operated. After a drawing by J. Absolon.
