* * * * * Part the Second. _Of the Nature of Whiteness and Blackness,_ CHAP. I. _The reason why the Author chose the Explication of Whiteness and Blackness_ (93.) _Wherein_ Democritus _thought amiss of these_ (94.) Gassendus _his Opinion about them_ (95.) _What the Author approves, and a more full Explication of White, makinig it a Multiplicity of Light or Reflections_ (96, 97.) _Confirm'd first by the Whiteness of the_ Meridian _Sun, observ'd in Water_ (98.) _and of a piece of Iron glowing Hot_ (99.) _Secondly, by the Offensiveness of Snow to the Travellers eyes, confirm'd by an example of a Person that has Travell'd much in Russia_ (100.) _and by an Observation out of_ Olaus Magnus (100.) _and that the Snow does inlighten and clear the Air in the Night, confirm'd by the Mosco Physician, and Captain_ James (101.) _But that Snow has no inherent Light, prov'd by Experience_ (102.) _Thirdly, by the great store of Reflections, from white Bodies observ'd in a darkned Room, and by their unaptness to be Kindled by a Burning-glass_ (103.) _Fourthly, the Specularness of White Bodies is confirm'd by the Reflections in a dark Room from other Bodies_ (104.) _and by the appearance of a River, which both to the Eye and in a darkned Room appear'd White_ (105, 106.) _Fifthly, by the Whiteness of distill'd_ Mercury, _and that of the_ Galaxie (107, 108.) _and by the Whiteness of Froth, rais'd from whites of Eggs beaten; that this Whiteness comes not from the Air, shew'd by Experiments_ (109, 110.) _where occasionally the Whiteness of Distill'd Oyls, Hot water, &c. are shew'd_ (111.) _That it seems not necessary the Reflecting Surfaces should be Sphærical, confirm'd by Experiments_ (112, 113.) _Sixthly, by the Whiteness of the Powders of transparent Bodies_ (114.) _Seventhly, by the Experiment of Whitening and Burnishing Silver._ (115, 116.)
