Page 566 - Thou art, of what sort the eternal life of the saints was to be, which eye hath not seen, nor ear heard, nor hath it entered into the heart of man to conceive.
Page 463 - ... the squares of the times of revolution of the planets about the sun are proportional to the cubes of their mean distances from the sun.

Page 567 - Open your lips, ye wonderful and fair ! Speak, speak ! the mysteries of those living worlds Unfold ! — No language ? Everlasting light, And everlasting silence ? — Yet the eye May read and understand. The hand of God Has written legibly what man may know, THE GLORY OF THE MAKER.

Thus, the earth on which he stands, and which has served for ages as the unshaken foundation of the firmest structures, either of art or nature, is divested by the astronomer of its attribute of fixity, and conceived by him as turning swiftly on its centre, and at the same time moving onwards through space with great rapidity.

" This," says Sir J. Herschel, " may serve as a specimen of the dreams in which astronomers, like other speculators, occasionally and harmlessly indulge.
