Σελίδα 138 - Acid from dissolved Metals, nor Metals the Acid from Mercury. Now, as in the great Globe of the Earth and Sea, the densest Bodies by their Gravity sink down in Water, and always endeavour to go towards the Center of the Globe; so in Particles of Salt, the densest Matter may always endeavour to approach the Center of the Particle: So that a Particle of Salt may be compared to a Chaos; being dense, hard, dry, and earthy in the Center; and rare, soft, moist, and watry in the Circumference.
Σελίδα 113 - For since the time of vibration is to the time of descent through half the length of the pendulum, as the circumference of a circle to its diameter, that is, as 3.14159 to 1?
Σελίδα 68 - Vapours and Exhalations as soon as they shall at any time begin to ascend from the Sun, and make them presently fall back again into him, and by that action increase his Heat much after the manner that in our Earth the Air increases the Heat of a culinary Fire. And the same weight may hinder the Globe of the Sun from being diminish'd, unless by the Emission of Light, and a very small quantity of Vapours and Exhalations.
Σελίδα 48 - If, therefore, the axis of the earth were perpendicular to the plane of its orbit, the...
Σελίδα 192 - Sulphur,) entring violently into the fix'd Body of the Ni.tre, fets loofe the Spirit of the Nitre, and excites a great Fermentation, whereby the Heat is farther augmented, and. the...
Σελίδα 138 - Putrefaction, and Death. If a very small quantity of any Salt or Vitriol be dissolved in a great quantity of Water, the Particles of the Salt or Vitriol will not sink to the bottom, though they be heavier in Specie than the Water, but will evenly diffuse themselves into all the Water, so as to make it as saline at the top as at the bottom. And does not this imply that the Parts of the Salt or Vitriol recede from one another, and endeavour to expand themselves...
Σελίδα 78 - Days have bin found to be of about the same length with ours. But the Inhabitants have no perceivable difference between Summer and Winter, the Axis of that Planet having very little or no inclination to his Orbit, as has been discover 'd by the Motion of his Spots.
Σελίδα 192 - Ebullition and a gentle Heat; and where it is quicker, it makes a greater Ebullition with more Heat; and where it is done at once, the Ebullition is contracted into a sudden Blast or violent Explosion, with a Heat equal to that of Fire and Flame.
Σελίδα 192 - B'jdy of the Nitre is alfo rarified into Fume, and the Explofion is thereby made more vehement and quick. For if Salt of Tartar be mixed with Gunpowder , and that Mixture be warmed till it takes Fire, the Explofion will be more violent and quick than that of Gunpowder alone, which cannot proceed from any other Caufe than the Action of the Vapor of the Gunpowder upon the Salt of Tartar, whereby that Salt is rarified. The Explofion of...
Σελίδα 67 - Atmosphere, does not so much as emit any Fume which can be perceived by Sight. In like manner the great weight of the...
