The same said, that upon the first appearance of Land from the Sea, the Mountain tops do shew themselves to be much more pointed than they really are, which was conjectured to arise from the Air or Mediums refraction, which is seen to cutt off the angles so much as to go beyond the perpendicular, and make it seem overhang.
Mr. Fatio said, that he had often observed that appearance of the overhanging of the Land which he conceived to be the reflection of the upper part, upon a surface somewhat higher, than that of the water, as for Example [Figure]
This surface so reflecting, Mr Hook was of opinion, was the surface of the thicker vapours of the Sea, which in still weather might be smooth enough to cast such a reflection.
