Penaud's machine, relying only on india rubber under torsion, flies for some fifty yards.

"But yours, when I first had the pleasure of meeting you, was not carrying you at all." "Something had gone wrong with the mechanism," answered Winter, sighing.
Consider the following abstract of Penaud's design as published in his patent of 1876, and comparison of this with the aeroplane that now exists will show very few divergences except for those forced on the inventor by the fact that the internal combustion engine had not then developed.
Two years before the publication of Penaud's patent Thomas Moy experimented at the Crystal Palace with a twin-propelled aeroplane, steam driven, which seems to have failed mainly because the internal combustion engine had not yet come to give sufficient power for weight.
