res, 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)
