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].)
The forty eighth Experiment, Of Tinging Glass Blew with Leaf Silver, and with Calcin'd Copper, and White with Putty (from [355] to [358].) Annotation the first, That this white Glass is the Basis of Ammels ([358].) Annotion the second, That Colour'd Glasses may be Compounded like Colour'd Liquors in Dying Fats ([359].) Annotation the third, Of Tinging Glass with Minerel Substances, and of trying what Metalls they contain by this means (from [360] to [362].) Annotation the fourth, That Metalls may be Ting'd by Mineralls ([362], [363].) Annotation the fifth, Of making several Kinds of Amauses or Counterfeit Stones (from [363] to [365].) Annotation the sixth, Of the Scarlet Dye, of the Stains of dissolv'd Gold and Silver ([366], [367]) Of the Greenness of Salt Beef, and Redness of Neats Tongues from Salts; of Gilding Silver with Bathe Water ([368], [369].) 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].) Annotation the third, That the Experiments related may Hint divers others ([378]) Annotation the fourth, That Alum is usefull for the preparing other than Vegetable Pigments ([379].)
The fiftieth Experiment, Of the Similar effects of Saccarum
