Worms (Vermes L.)

1663. Worms (Vermes L.) are distinguished from apterous and winged insects by being altogether destitute of legs at every period of their existence. It will be sufficient, for our present purpose, to divide them into two artificial groups: naked worms, which will include the earth or dew worms, and the different species of slugs; and shelly worms, or those provided with a shelly covering, such as the garden and banded snails. * Fumes of brimstone, or, better still, the exhalation given out by bruised laurel leaves, will more effectually destroy the red spider than simply syringing the plants.
