16. That odorous bodies may be made more odorous by contrition proceeds
from this, that being broken into many parts, which are all odorous, the
air, which by respiration is drawn from the object towards the organ,
doth in its passage touch upon all those parts, and receive their
motion. Now, the air toucheth the superficies only; and a body having
less superficies whilst it is whole, than all its parts together have
after it is reduced to powder, it follows that the same odorous body
yieldeth less smell whilst it is whole, than it will do after it is
broken into smaller parts. And thus much of smells.
[Sidenote: The first organ of tasting; and why some savours cause
nauseousness.]
17. The taste follows; whose generation hath this difference from that
of the sight, hearing, and smelling, that by these we have sense of
remote objects; whereas, we taste nothing but what is contiguous, and
doth immediately touch either the tongue or palate, or both. From whence
it is evident, that the cuticles of the tongue and palate, and the
nerves inserted into them are the first organ of taste; and (because
from the concussion of the parts of these, there followeth necessarily a
concussion of the _pia mater_) that the action communicated to these is
propagated to the brain, and from thence to the farthest organ, namely,
the heart, in whose reaction consisteth the nature of sense.
Now, that savours, as well as odours, do not only move the brain but the
stomach also, as is manifest by the loathings that are caused by them
both; they, that consider the organ of both these senses, will not
wonder at all; seeing the tongue, the palate and the nostrils, have one
and the same continued cuticle, derived from the _dura mater_.
And that effluvia have nothing to do in the sense of tasting, is
manifest from this, that there is no taste where the organ and the
object are not contiguous.
By what variety of motions the different kinds of tastes, which are
innumerable, may be distinguished, I know not. I might with others
derive them from the divers figures of those atoms, of which whatsoever
may be tasted consisteth; or from the diverse motions which I might, by
way of supposition, attribute to those atoms; conjecturing, not without
some likelihood of truth, that such things as taste sweet have their
particles moved with slow circular motion, and their figures spherical;
which makes them smooth and pleasing to the organ; that bitter things
have circular motion, but vehement, and their figures full of angles, by
which they trouble the organ; and that sour things have strait and
reciprocal motion, and their figures long and small, so that they cut
and wound the organ. And in like manner I might assign for the causes of
other tastes such several motions and figures of atoms, as might in
probability seem to be the true causes. But this would be to revolt from
philosophy to divination.
