By endeavouring to improve one quality, he may impair the beauty of another.

The richer mould which he would employ to increase the size of his plant would probably burst the calyx, and destroy at once its symmetry.

In a similar manner, the forcing manure used to bring about the French Revolution, and to give a greater freedom and energy to the human mind, has burst the calyx of humanity, the restraining bond of all society; and, however large the separate petals have grown, however strongly, or even beautifully, a few of them have been marked, the whole is at present a loose, deformed, disjointed mass, without union, symmetry, or harmony of colouring.
Were it of consequence to improve pinks and carnations, though we could have no hope of raising them as large as cabbages, we might undoubtedly expect, by successive efforts, to obtain more beautiful specimens than we at present possess.

No person can deny the importance of improving the happiness of the human species.

Every the least advance in this respect is highly valuable.
