Synopsis
Excerpt from Ophthalmic Lenses, Dioptric Formulae for Combined Cylindrical Lenses: The Prism-Dioptry, and Other Optical Papers, With One Hundred and Ten Original Diagrams
In the Treatise on Ophthalmic Lenses an endeavor is made, by means of graphic and analytic methods, to guide the novice upon a path by which he may easily acquire a knowledge of lenticular refraction with out recourse to mathematics. The text is, therefore, confined to the description of a series of diagrams, by aid of which the principles involved are presented in their natural order of succession.
