describe exhibit expressed knowledge last novelty obstacle refer remove
To remove this obstacle I repeat or refer to such knowledge as has come under my notice, my own previously expressed views, and also describe and exhibit my last experiments and explain their novelty and utility.
again air effect flat heavy letting pushes quite suppose wave
As to the effect of the wave on the air, we will suppose the water to be quite flat and the air motionless, a heavy undulation comes on the scene, it has to pass, so it pushes the air up with its face, letting it fall again as its back glides onwards.
continued counteract distant inevitably multitude plane planes power reservoir simply stored using wave work
The plane is simply abstracting the power stored in the wave by a distant gale, and using it to counteract gravity. And if the work be continued long enough, or a multitude of planes be continually drawing on the reservoir of power, the wave must inevitably be flattened.
chamber charge crank external flows inlet moved pipe several valve
The wings are moved several times by hand to charge the crank chamber with mixture, which flows on through the external pipe and inlet valve to the compression space and cylinder.
apply common mobile parts seen separate skill steps
Common sense steps in here and says: Separate the parts you want to be mobile from the parts you want to be inert. You have seen the result, and I know many have the skill to apply it.
almost appears closer rising surface tip uplift
The closer the bird is to the surface of the water, the firmer and more inelastic is the uplift of the rising air. The bird appears to almost feel the surface with the tip of its weather wing.
angles apparently attention direct nearly noticed position regard rising side speedily wave
If you direct your attention to the position of a bird with regard to the wave surface, it will speedily be noticed to be nearly always on the rising side or face of the wave and moving apparently at right angles to the wave's course, but really diagonal to it.
