^{page 262 note 1} Mr. Hunt asks, “Would Mr. Mellard Reade give his reasons for believing that waves ever cause surface particles in deep water to move in a vertical circle, or an ellipse, not very different from one having the longer axis vertical P” If Mr. Hunt will watch a cork floating in water on which wind waves are generated, he will, I think, see that the vertical oscillatory movement of the cork is as great as or greater than the horizontal. The composition of the two movements will give either a circle or an ellipse. This is no discovery of Mr. Eeade's, but a fact known to every physicist.
