I shall only add farther, that since the A £ ftphere is a gravitating fluid Substance , it must be ‘ u ^ iC \\to the attracting Power of the Sun and Moon, aS 0 (as of the Earth : and therefore when the InsiueNthose Luminaries, either singly or conjointly, lS W 0 tfsite to that of the Earth, the fame Effects must

Now because of an Equality of Pressure orV^ Astin the Atmosphere in unequal Altitudes of Air, 'd ^ otnever be sensible of an Aerial Tide , either of ^Flood, by the Barometer ; and can only know st. pj-O'*Position of the heavenly Bodies. However as £ "^,itl/digious Protuberance of the Atmosphere is confollowing the Moon, it must of course produce * ^ tOtion in all Parts, and so produce a Wind more or r e devery Place, which, as it conspires with, or is °r to
