told him by a very Eminent Man_ (19.) _But the strange Instances
afforded by such as are Bit by the_ Tarantula _are omitted, as more
properly deliver'd in another place_. (20.)

Chap. 3. _That the Colour of Bodies depends chiefly on the disposition of
the Superficial parts, and partly upon the Variety of the Texture of the
Object_ (21.) _The former of these are confirm'd by several Persons_ (22.)
_and two Instances, the first of the Steel mention'd before, the second of
melted Lead_ (23, 24.) _of which last several Observables are noted_ (25.)
_A third Instance is added of the Porousness of the appearing smooth
Surface of Cork_ (26, 27.) _And that the same kind of Porousness may be
also in the other Colour'd Bodies; And of what kind of Figures, the
Superficial reflecting Particles of them may be_ (28.) _and of what Bulks,
and closeness of Position_ (29.) _How much these may conduce to the
Generation of Colour instanc'd in the Whiteness of Froth, and in the
mixtures of Dry colour'd Powders_ (30.) _A further explication of the
Variety that may be in the Superficial parts of Colour'd Bodies, that may
cause that Effect, by an example drawn from the Surface of the Earth_ (31.)
_An Apology for that gross Comparison_ (32.) _That the appearances of the
Superficial asperities may be Varied from the position of the Eye, and
several Instances given of such appearances_ (33, 34, 35.) _That the
appearance of the Superficial particles may be Varied also by their Motion,
confirm'd by an Instance of the smoaking Liquor_ (35.) _especially if the
Superficial parts be of such a Nature as to appear divers in several
Postures, explain'd by the variety of Colours exhibited by the shaken
Leaves of some Plants_ (36.) _and by changeable Taffities_ (37, 38, 39.)
_The Authors wish that the Variety of Colours in Mother of Pearl were
examin'd with a_ Microscope (40.) _And his Conjectures, that possibly good_
Microscopes _might discover those Superficial inequalities to be Real,
which we now only imagine with his reasons drawn partly from the
Discoveries of the_ Telescope, _and_ Microscope (41.) _And partly also from
the Prodigiously strange example of a Blind man that could feel Colours_
(42.) _whose History is Related_ (43, 44, 45.) _The Authors conjecture and
thoughts of it_ (46, 47, 48, 49.) _and several Conclusions and Corollaries
drawn from it about the Nature of Blackness and Black Bodies_ (50, 51, 52.)
_and about the Asperities of several oth
