Some gifted adventurer is always sailing round the world of art and science, to bring home costly merchandise from every port.

A book becomes a mirror, with the author's face shining over it. Talent only gives an imperfect image,--the broken glimmer of a countenance. But the features of genius remain unruffled. Time guards the shadow. Beauty, the spiritual, Venus,--whose children are the Tassos, the Spensers, the Bacons,--breathes, the magic of her love, and fixes the face forever.

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.

The drama embraces and applies all the beauties and decorations of poetry. The sister arts attend and adorn it. Painting, architecture, and music are her handmaids. The costliest lights of a people's intellect burn at her show. All ages welcome her.

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.

Association is the delight of the heart, not less than of poetry. Alison observes that an autumn sunset, with its crimson clouds, glimmering trunks of trees, and wavering tints upon the grass, seems scarcely capable of embellishment. But if in this calm and beautiful glow the chime of a distant bell steal over the fields, the bosom heaves with the sensation that Dante so tenderly describes.

Taste is not stationary. It grows every day, and is improved by cultivation, as a good temper is refined by religion. In its most advanced state it takes the title of judgment. Hume quotes Fontenelle's ingenious distinction between the common watch that tells the hours, and the delicately constructed one that marks the seconds and smallest differences of time.
