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.

The importance of the romantic element does not rest upon conjecture. Pleasing testimonies abound. Hannah More traced her earliest impressions of virtue to works of fiction; and Adam Clarke gives a list of tales that won his boyish admiration. Books of entertainment led him to believe in a spiritual world; and he felt sure of having been a coward, but for romances. He declared that he had learned more of his duty to God, his neighbor and himself from Robinson Crusoe than from all the books, except the Bible, that were known to his youth.

Poetry deserves the honor it obtains as the eldest offspring of literature, and the fairest. It is the fruitfulness of many plants growing into one flower and sowing itself over the world in shapes of beauty and color, which differ with the soil that receives and the sun that ripens the seed. In Persia, it comes up the rose of Hafiz; in England, the many-blossomed tree of Shakespeare.

It is the empiric who never fails.

Humor is the pensiveness of wit.

Genius finds its own road and carries its own lamp.

Occasionally a single anecdote opens a character; biography has its comparative anatomy, and a saying or a sentiment enables the skilful hand to construct the skeleton.
