The last-mentioned, during 46 years of study, first attracted my attention to this principle, and is the only one whom I have yet met who has made ornithopter models really fly. They were simple contrivances with loose surfaces to test the late Mr. Breary's " skate " theories. The roller type, of which I enclose a diagram, is of my own desig...

Strictly speaking, the term " orthopter" denotes nothing more nor less than a something having straight or regular wings ; whereas the term " ornithopter " denotes a some- thing having bird-like wings. The question is, therefore, what fundamental qualities of a flapping-flight machine assimilates its wings to those of the ...
