EXPERIMENT I. A way of kindling Brimstone in vacuo Boyliano unsuccessfully tried.

EXPER. II. An ineffectual attempt to kindle Sul∣phur in our Vacuum another way.

ADVERTISEMENT.

EXPER. IV. A differing Experiment to the same purpose with the former.

EXPER. V. About an endeavour to fire Gun∣powder in vacuo with the Sun∣beams.

EXPER. VI. An attempt to fire Gunpowder in vacuo, by means of a hot Iron.

APPENDIX.

EXPER. VII. Reciting another way, whereby the firing of Gunpowder in vacuo Boyliano was attempted.

EXPER. VIII. About a tryal made to fire Gunpow∣der in our Vacuum by the help of Sparks.

EXPER. IX. Two ways of making Aurum fulmi∣nans go off in our exhausted Re∣ceiver.

title page

Of the Difficulty of Preserving Flame without Air.

EXPER. I. Reciting an attempt to preserve the flame of Brimstone without Air.

EXPER. II. Relating a Tryal about the Duration of the flame of Sulphur in vacuo Boyliano.

EXPER. III. Of the lasting of the flame of a Me∣talline substance in the same Va∣cuum.

EXPER. IV. Of the Duration of the Flame of Spirit of Wine impregnated with a metal in the Exhausted Recei∣ver.

EXPER. I. An ineffectual attempt to make Flame kindle Spunck in an Ex∣hausted Receiver.

EXPER. II. An unprosperous attempt to make Flame kindle Camphire without the help of Air.

EXPER. III. A strange Experiment upon Gun∣powder, shewing, that though it were fired it self, yet would not fire the contiguous grains in Va∣cuo Boyliano.

EXPER. IV. Reciting another Attempt to confirm the former.

EXPER. V. Briefly mentioning two differing Tryals with two differing Events, to kindle Gunpowder in our Va∣cuum.

EXPER. III. Of what happen'd to the Light of Glo-worms in the Exhausted Re∣ceiver.

EXPER. IV. Containing a variation and im∣provement of the foregoing Tryal.

EXPER. V. Wherein the former Inquiry is far∣ther prosecuted.

EXPER. VI. Made to examine whether Animals be heavier dead than alive.
