Op spiders there are many species ; most of them extend
their labors no further 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.*
Modern naturalists do not rank spiders among insects, be-
cause they have no antenna?, and no division between the head
* Don Luis Nee observed on certain trees growmg in Chilpancingo, Tixtala in
South America, ovate nests of caterpillars, eight inches long, vi'hich the inhabi
tants manufacture into stockings and handkerchiefs.—Annals of Botany, 2d, p
104.
