Experiments and Considerations Touching Colours | Page 9

with Acid and
Sulphureous Salts on the Red Tinctures of Clove-july-flowers,
Buckthorn Berries, Red-Roses, Brasil_, &c. (262, 263.)
The twenty seventh Experiment, _of the changes of the Colour of
Jasmin flowers, and Snow drops, by Alcalizate and Sulphureous Salts_
(263, 264.)
The twenty eighth Experiment, _of other differing Effects on
Mary-golds, Prim-roses, and fresh Madder_ (265.) _with an
Admonition, that these Salts may have differing Effects in the changing
of the tinctures of divers other Vegetables_ (266, 267.)
The twenty ninth Experiment, _of the differing Effects of these Salts on
Ripe and Unripe Juices, instanced in Black-berries, and the Juices of
Roses_ (from 267 to 270.) _Two reasons, why the Author added this
twenty ninth_ Experiment, _the last of which is confirm'd by an
Instance of Mr._ Parkinson, consonant to the Confession of the Makers
of such Colours (272.)
The thirtieth Experiment, _of several changes in Colours by Digestion,
exemplify'd by an_ Amalgam of Gold and Mercury _and by Spirit of
Harts-horn. And (to such as believe it) by the changes of the_ Elixir.
The thirty first Experiment, _shewing that most Tinctures drawn by
Digestion Incline to a Red, instanc'd in_ Jalap, Guaicum, _Amber,
Benzoin, Sulphur, Antimony_, &c. (276, 277.)

The thirty second Experiment, _That some Reds with Diluting turn
Yellow, others not, exemplify'd by the Tincture of_ Cochineel, and by
Balsam of Sulphur, Tinctures of Amber, &c. (277, 278, 279.)
The thirty third Experiment, of a Red Tincture of Saccarum Saturni and
Oyl of Turpentine made by Digestion (279.)
The thirty fourth Experiment, of drawing a Volatile red Tincture of
Mercury, _whose Steams were white, but it would Tinge the Skin
black_ (279, 280.)
The thirty fifth Experiment, of a suddain way of making a Blood red
Colour with Oyl of Vitriol, and Oyl of Anniseeds, two transparent
Liquors (280, 281.)
The thirty sixth Experiment, _of the Degenerating of several Colours
exemplify'd in the last mention'd Blood red, and by Mr._ Parkinsons
relation of Turnsol, _by some Trials with the Juice of Buck-thorn
Berries, and other Vegetables, to which several notable Considerations
and Advertisements back'd with_ Experiments _are adjoyn'd_ (from
281 to 288.)
The thirty seventh Experiment, Of Varying the Colour of the Tinctures
of Cochineel, _Red-cherries, and Brasil, with Acid and Sulphureous
Salts, and divers Considerations thereon_ (from 288 to 290.)
The thirty eighth Experiment, _About the Red fumes of some, and
White of other distill'd Bodies, and of their Coalition for the most part
into a transparent Liquor_ (290, 291.) _And of the various Colours of
dry Sublimations, exemplify'd with several_ Experiments (292, 293,
294.)
The thirty ninth Experiment, Of Varying the Decoction of Balaustiums
with Acid and Urinous Salts (294, 295.) Some Annotations wherein two
Experiments of Gassendus _are Related, Examined, and Improv'd_
(from 295 to 302.)
The fortieth Experiment, Of the no less Strange than Pleasant changes

made with a Solution of Sublimate (from 301 to 306.) The difference
between a Chymical axd Philosophical Solution of a Phænomenon (307,
308.) The Authors Chymical Explication of the Phænomena, confirm d
by several Experiments made on Mercury, with several Saline Liquors
(from 308 to 310.) An Improvement of the fortieth Experiment, by a
fresh Decoction of Antimony in a Lixivium (311, 312, 313.)
_Reflections on the tenth, twentieth, and fortieth_ Experiments,
_compar'd together, shewing a way with this Tincture of Sublimate to
distinguish whether any Saline Body to be examin'd be of a Urinous or
Alcalizate Nature_ (from 314 to 317.) The Examination of Spirit of
Sal-armoniack, and Spirit of Oak by these Principles (from 316 to 319.)
_That the Author knows ways of making highly Operative Saline
bodies, that produce none of the before mention'd effects_ (319, 320.)
Some notable Experiments about Solutions and Precipitations of Gold
and Silver (320, 321.)
The one and fortieth Experiment, Of Depriving a deep Blew Solution of
Copper of its Colour (322.) _to which is adjoyn'd the Discolouring or
making Transparent a Solution of Verdigrease, &c. and another of
Restoring or Increasing it_ (322, 323.)
The forty second Experiment, Of changing a Milk white Precipitate of
Mercury _into a Yellow, by Affusion of fair Water, with several
Considerations thereon_ (from 323 to 326.)
The forty third Experiment, _Of Extracting a Green Solution with fair
Water out of imperfectly Calcin'd Vitriol_ (327.)
The forty fourth Experiment, _Of the Deepning and Diluting of several
Tinctures, by the Affusions of Liquors, and by Conical Glasses that
contain'd them, Exemplify'd in the Tinctures of_ Cochineel, Brasil,
Verdigrease, Glass, Litmus, of which last on this occasion several
pleasant Phænomena are related (from 328 to 335.) _To which are
adjoyn'd certain Cautional Corollaries_ (335, 336.) _The Waterdrinker
and some of his Legerdemain tricks related._(337.)
The forty fifth Experiment, _Of the turning Rhenish and White Wine
into a lovely Green, with a preparation of Steel _(338, 339.) _Some

further Trial
