in too large a Sense,
the Cautionary instance of Froth is alleged and insisted on_ (78, 79.)
_That the Duration is not a sufficient Characteristick, exemplify'd by the
duration of Froth, and other Emphatical Colours, and the suddain fading of
Flowers, and other Bodies of Real ones_ (80.) _That the position of the Eye
is not necessary to the discerning Emphatical Colours, shew'd by the seeing
white Froth, or an Iris cast on the Wall by a Prism, in what place of the
Room soever the Eye be_ (81.) _which proceeds from the specular Reflection
of the Wall_ (82.) _that Emphatical Colours may be Compounded, and that the
present Discourse is not much concern'd, whether there be, or be not made a
distinction between Real and Emphatical Colours_. (83.)
Chap. 5. _Six Hypotheses about Colour recited_ (84, 85) _Why the Author
cannot more fully Speak of any of these_ (86.) _nor Acquiesce in them_ (87,
88.) _What_ Pyrophilus _is to expect in this Treatise_ (88, 89.) _What
Hypothesis of Light and Colour the Author most inclines too_ (90.) _Why he
thinks neither that nor any other sufficient; and what his Difficulties
are, that make him decline all Hypotheses, and to think it very difficult
to stick to any._ (91, 92.)

CHAP. I.
_The reason why the Author chose the Explication of Whiteness and

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,
