These may sometimes be seen by the naked eye ; but they are often so minute that 3,000 of them are contained in an inch.
Page 179 - Herschel attributes this state of vision to a defect in the sensorium, by which it is rendered incapable of appreciating exactly those differences between rays on which their colour depends.
Page 151 - ... they could not, at first, be persuaded of the reality of the appearance ; but soon became so thoroughly convinced, by the cliffs gradually appearing more elevated, and approaching nearer, as it were, that they pointed out, and named to...

Page 97 - ... left, or on any other side of it, provided that in all these cases it falls upon the surface in the same manner, or, what amounts to the same thing, the beam of solar light has the same properties on all its sides; and this is true, whether it is white light as directly emitted from the sun, or whether it is red light, or light of any other colour.
Page 175 - With the aid of these facts, the theory of accidental colors will be readily understood. When the eye has been for some time fixed on the red wafer, the part of the retina occupied by the red image is strongly excited, or, as it were, deadened by its continued action.
