Of spiders there are many species; most of them extend their labors no farther than merely to make a web to ensnare and detain their food. But others are known to go beyond this, and spin a bag in the form of a cocoon, for the protection of their eggs, nearly similar to that of the silk-worm.[1]

Modern naturalists do not rank spiders among insects, because they have no antennæ, and no division between the head

  1. Don Luis Nee observed on certain trees growing in Chilpancingo, Tixtala in South America, ovate nests of caterpillars, eight inches long, which the inhabitants manufacture into stockings and handkerchiefs.—Annals of Botany, 2d, p 104.
