If the earth should cease to attract its waters to itself all the waters of the sea would be raised and would flow to the body of the moon.

The sphere of the attractive virtue which is in the moon extends as far as the earth, and entices up the waters; but as the moon flies rapidly across the zenith, and the waters cannot follow so quickly, a flow of the ocean is occasioned in the torrid zone towards the westward.

 
Johannes Kepler
 

J. Kepler was the first (that I know of) that discover'd the true cause of the Tide, and he explains it largely in his Introduction to the Physics of the Heavens, given in his Commentaries to the Motion of the Planet Mars, where after he has shewn the Gravity or Gravitation of all Bodies towards another, he thus writes: "The Orb of the attracting Power, which is in the Moon is extended as far as the Earth, and draws the Waters under the Torrid Zone, acting upon places where it is vertical, insensibly on included Seas, but sensibly on the Ocean, whose Beds are large, and the Waters have the liberty of reciprocation, that is, of rising and falling"; and in the 70th Page of his Lunar Astronomy,—"But the cause of the Tides of the Sea appear to be the Bodies of the Sun and Moon drawing the Waters of the Sea."

 
Johannes Kepler
 

Another great change happened nearly two thousand years after the earth was made. It was baptized by water. A great flow of water come, the great deep was broken up, the windows of heaven were opened from on high, and the waters prevailed upon the face of the earth, sweeping away all wickedness and transgression-a similitude of baptism for the remission of sins. God requires the children of men to be baptized. What for? For the remission of sins. So he required our globe to be baptized by a flow of waters, and all of its sins were washed away, not one sin remaining.

But to return to Kepler, his great sagacity, and continual meditation on the planetary motions, suggested to him some views of the true principles from which these motions flow. In his preface to the commentaries concerning the planet Mars, he speaks of gravity as of a power that was mutual betwixt bodies, and tells us that the earth and moon tend towards each other, and would meet in a point so many times nearer to the earth than to the moon, as the earth is greater than the moon, if their motions did not hinder it. He adds that the tides arise from the gravity of the waters towards the moon. But not having just enough notions of the laws of motion, he does not seem to have been able to make the best use of these thoughts; nor does he appear to have adhered to them steadily, since in his epitome of astronomy, published eleven years after, he proposes a physical account of the planetary motions, derived from different principles.

 
Johannes Kepler
 

But Conversation, choose what theme we may,
And chiefly when religion leads the way,
Should flow, like waters after summer show'rs,
Not as if raised by mere mechanic powers.

 
William Cowper
