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 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 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 Authors Apology for Recording some already known Experiments, without mentioning their Authors (from 350 to 352.) Annotation the second, That some Minerals also by Dissolutions in Menstruums may exhibit divers Colours. Annotation the third, That Metalls disclose other Colours by Precipitations, instanc'd in Mercury (from 353 to 355.)

And Tinging the Nails and Skin with Alcanna (369)

The forty ninth Experiment, Of making Lakes (369.) A particular example in Turmerick (370, 371.) Annotation the first, That in Precipitations wherein Allum is a Coefficient, a great part of them may consist of the Stony particles of that Compound Body (from 372 to 375.) Annotation the second, That Lakes may be made of other Substances, as Madder, Rue, &c. but that Alcalizate Salts do not Always Extract the same Colour of which the Vegetable appears (from 376 to 378.)
