t to instance the olfactory organ. If
we scent the essences of rose or jasmine, on the second presentation,
they are recognised as having occurred before: should we have smelled
the same perfumes from the living plants that exhale them, and by the
_eye_ noticed them, we should experience a phantasm or Idea of the
figure of the plants, but there would be no phantasm of the odour. The
excitation of the phantasm associated with the perception, and the
recollection of the perception without the phantasm, by the attribution
of a name, is, for the present, purposely concealed.

quo agit_, be defined.

[3] Of the supposed operations of these Ideas, and the purposes to which
they are subjected, a few, among abundant instances, are selected from
Mr. Locke's Essay. "Some Ideas _forwardly_ offer themselves to all men's
understanding; some sorts of truths result from any Ideas, as soon as
the mind puts _them_ into propositions: other Truths require a _train_
of Ideas _placed in order_."--_Vol._ I. _p._ 63.

"When the understanding is once stored with these simple Ideas, it has
the power to _repeat_, _compare_, and _unite_ them, even to an almost
infinite variety, and so can make at pleasure _new_ complex
Ideas."--_Vol._ I. _p._ 81.

"The next operation we may observe in the mind about its Ideas, is
COMPOSITION, whereby it puts together several of those simple ones it
has received from sensation and reflection, and _combines_ them into
complex ones."--_Vol._ I. _p._ 118.

"If either by any sudden very strong impression, or long fixing his
fancy upon one sort of thoughts, _incoherent_ Ideas have been _cemented_
together so powerfully, as to remain united."--_Vol._ I. _p._ 121.

"But there are degree of Madness as of folly, the disorderly _jumbling_
Ideas together, in some more, and some less." _Vol._ I. _p._ 122.

"The acts of the mind wherein it exerts its power over its simple Ideas,
are chiefly three. 1st. Combining several simple Ideas into one
_compound one_, and _thus_ all complex Ideas are made. The second, is
bringing _two Ideas_, whether simple or complex together, and _setting_
them by one another, so as to take a view of them _at once_, without
uniting them into one; by which way it gets all its Ideas of relations.
The third, is _separating_ them from all other Ideas that _accompany_
them in their real existence; this is called Abstraction."--_Vol
