2. That they are furnifhed with antennae, which are placed
upon the fore part o f the head; thefe are jointed, and moveable
in various directions.
3. That no infeft in it’s perfect ftate, or after it has gone
through all it’s transformation, has lefs than fix legs, though
many have more. There are fome moths, whofe two fore feet
are fo fmall as fcarcely to deferve that name. A proper attention
to the nature and number-of the feet of infefis would tend
to fix their real rank in that fcale o f animated nature, which is
handed down to us in the facred fcriptures; a fcale which, from
the lively reprefentations it holds forth, as well as their moral
applications to the purpofes of life, and the fource from whence
it is derived, Ihews that it is replete with the moil important
information.
4- That infeCts have neither the organs of fmell nor hearing;
at leaft they have not as yet been difcovered, though it is reported
that Fabricius has lately found and defcribed the organs of hearing
in the lobfter.
5. That they do not refpire air by the mouth, but that they
infpire and exhale it, by means o f organs which are placed on
the body.
6. That they move the jaws from right to left, not up and
1A down.
7. That they have neither eye-lid nor pupil.
T o thefe we may alfo add, that the mechanifm refulting from
the life of infedts is not of fo compound a nature as in animals
o f a larger fize. They have.lefs variety o f organs, though fome
o f the organs are more multiplied ; and it is by the number and
fituation o f thefe that their rank in the great fcale of beings is to
be determined.
Thefe charafters are often united in the fame infefi ; there are,
however, fome fpecies in which one or two of them are wanting.
Every microfcopic obferver, who wilhes to avail himfelf o f the
difcoyeries of other writers, or to communicate intelligibly
his own, will find it neceffary to make himfelf mailer o f the
various claffes, genera, &c. into which infefts have been
divided by L innasus. All fyftems have their defects, and it is
highly probable that this may be the cafe with that o f the
celebrated Linnaeus : but the purpofe of fcience is anfwered by
ufing thofe diferiminations which are generally adopted.
The following general idea of the Lmnasan clalfes may feive as
a foundation for this knowledge : a fuller account may be obtained
by confulting the under-mentioned works.
