There are many species of mites, beside the itch animal and mite above:
to the naked eye, they appear like moving particles of dust: but the
microscope discovers them to be perfect animals, having as regular a
figure, and performing all the functions of life as perfectly as
creatures that exceed them many times in bulk: their eggs are so small
that a regular computation shews that 90 millions of them are not so
large as a common Pigeon's egg.
The Chego is a very small animal, about one fourth the size of a common
flea: it is very troublesome, in warm climates, to the poor blacks, such
as go barefoot, and the slovenly: it penetrates the skin, under which it
lays a bunch of eggs, which swell to the bigness of a small pea.
The Deathwatch, of which there are two kinds, is an insect famous for a
ticking noise, like a watch, which superstitious people take for a
presage of death, in the family where it is heard.
