Romance is the truth of imagination and boyhood. Homer's horses clear the world at a bound. The child's eye needs no horizon to its prospect. The oriental tale is not too vast. Pearls dropping from trees are only falling leaves in autumn. The palace that grew up in a night merely awakens a wish to live in it. The impossibilities of fifty years are the commonplaces of five.

How deep is the magic of sound may be learned by breaking some sweet verses into prose. The operation has been compared to gathering dew-drops, which shine like jewels upon the flower, but run into water in the hand. The elements remain, but the sparkle is gone.

It is the empiric who never fails.

Many books belong to sunshine, and should be read out of doors. Clover, violets, and hedge roses breathe from their leaves; they are most lovable in cool lanes, along field paths, or upon stiles overhung by hawthorn, while the blackbird pipes, and the nightingale bathes its brown feathers in the twilight copse.

Books, of which the principles are diseased or deformed, must be kept on the shelf of the scholar, as the man of science preserves monsters in glasses. They belong to the study of the mind's morbid anatomy, and ought to be accurately labelled. Voltaire will still be a wit, notwithstanding he is a scoffer; and we may admire the brilliant spots and eyes of the viper, if we acknowledge its venom and call it a reptile.

Newton found that a star, examined through a glass tarnished by smoke, was diminished into a speck of light. But no smoke ever breathed so thick a mist as envy or detraction.

The history of men of science has one peculiar advantage, as it shows the importance of little things in producing great results. Smeaton learned his principle of constructing a lighthouse, by noticing the trunk of a tree to be diminished from a curve to a cyclinder ... and Newton, turning an old box into a water-clock, or the yard of a house into a sundial, are examples of those habits of patient observation which scientific biography attractively recommends.
