Or whether the Moon, may not have the fame Influence in railing a Tide, and continuing the Circulation of it, through the vaft Ocean of Air above, as fhe is found by Experience to caufe in the feveral Oceans of Water here below' ? Or laftly, whether the Communication be¬ twixt the polar Regions, may not depend upon other Caufes unknown to us; and as it is certain from the common EffeCts and Operations of the Load-Stone, that there is a continual Stream of magnetic Particles, flowing near the Surface of the Earth, and paffmg from Pole to Pole : So, whether there may not, in like manner, be fome- thing analagous to it, palling through the middle Regions of the Almoffhere, in a Stream of Vapours, or Particles, intenfely cold, and thereby anfwering the great Ends of Nature, in cooling the upper Regions of the Air, in giving a Check to the Rife of the Vapours, in condenling and precipitating many of them in Dews, or Rains, in form¬ ing the feveral Kinds of Meteors, in^ actu¬ ating and giving Force and Strength to the Winds, which, betides other Caufes, feem ' to depend, as well upon the frequent and Hidden Condenfations of the Air by Cold, as upon the Rarefadion of it by Heat; and to
