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.

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.
