    This is so absolutely true, that not only One Person cannot choose for another — but -One Eye has often very little notion what Glass will be best even for its own Brother, so extremely does the Left Eye occasionally differ from the Right. No faculty of man varies more in its na- ture, or is susceptible of a higher degree of Improvement and Refinement by Art, than the Sense of Sight. The highest degrees of its discriminating power are acquired slowly and imperceptibly. From organic imperfection and neglect of cultivation,* many People pass through Life “who (it may be said, comparatively,) never See—z.e. whose Eyes never have the faculty of accurately appreciating either Form, or Colour :—to very few is it given to perceive and to portray both. “ “ Every person acquainted with Optics and the na- ture of vision, knows that what is generally comprehended under the term Seeing, is a complex operation ; an art acquired by degrees, in which judgment and imagination are concerned, together with simple perception.”—CrisP on Vision, 8vo. 1796, p. 106.
