Experiments and Considerations Touching Colours | Page 9

_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 Ph?nomenon (307, 308.) The Authors Chymical Explication of the Ph?nomena, 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 Ph?nomena 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 made about these Tinctures, and a Similar_ Experiment of Olaus Wormius (340.)
The forty sixth Experiment, Of the Internal Colour of Metalls exhibited by Calcination (341, 342, 343.) Annotation _the first, That several degrees of Fire may disclose a differing Colour_ (343.) Annotation _the second, That the Glasses of Metalls may exhibit also other Kinds of Colours_ (344.) Annotation _the third, That Minerals by several degrees of Fire may disclose several Colours_(345).
Experiment _the forty seventh, Of the Internal Colours of Metalls disclos'd by their Dissolutions in several_ Menstruums (from 345 to 350.) Annotation _the first, The
