CHAP. 25. (22.)—THE BOMBYX OF ASSYRIA.
A fourth class of this kind [Note] of insect is the bombyx, [Note] which
is a native of Assyria, and is of larger size than any of those
which have been previously mentioned. They construct their
nests of a kind of mud which has the appearance of salt, and
then fasten them to a stone, where they become so hard, that
it is scarcely possible to penetrate them with a dart-even.
In these nests they make wax, in larger quantities than bees,
and the grub which they then produce is larger.
