- Tides always go in couples; if there is a tide on one side of a globe there will be a corresponding tide on the other side.
- The cause is to be found in the law that the force of gravitation varies inversely as the square of the distance; the attraction on the nearest surface of the body exercised by another body is greater than on its centre, and greater yet than on its opposite surface.
- If two great globes attract each other, each tends to draw the other out into an ellipsoidal figure; they must be more rigid than steal to resist this - and even then they cannot altogether resist.
- If they are liquid or gaseous they will yield readily to the force of distortion, the amount of which will depend upon their distance apart, for the nearer they are the greater becomes the tidal strain.
- If they are encrusted without and liquid or gaseous in the interior, the internal mass will strive to assume the figure demanded by the tidal force, and will, if it can, burst the restraining envelope.
