What difference that known Property of the Air, which is not in Water, makes in the Case, I shall shew anon; setting aside the Consideration of that for the present; It is certain, That as the Sea is, so must our Air, twice every 25 Hours, be rais'd upwards to a considerable height, by the Attraction of the Moon coming to the Meridian; so that instead of a Spherical, it must form it self into a Spheroidal, or Oval Figure, whose longest Diameter being produced, would pass thro' the Moon. That the like Raising must follow as often as the Sun is in the Meridian of any Place, either above or below the Horizon. Moreover, That this Elevation is greatest upon the New and Full Moons, because both Sun and Moon do then conspire in their Attraction; least on the Quarters, in that they then drawing different ways, 'tis only the Difference of their Actions produces the Effect. Lastly, That this Intumescence will be of a middle degree, at the time between the Quarters, and New and Full Moon.
From the same Principles, The Motion upwards of the Air will be strongest of all about the Equinoxes;
