enabled to remember it. If his hand had been duly educated he
might form its model, or chisel it from a block of marble; or on a
plain surface, according to the rules of art, might make a drawing of
the animal, and with such exactitude of its different _members_, that it
would appear to those who compared it with the original, that he
perfectly _re-membered_ it. To recollect is only a different figure for
the same process, and implies to re-gather or collect, those parts which
have been scattered in different directions.

The perceptions we obtain by our different senses are all capable of
being remembered, but in different ways. Those which we derive from
sight, may be communicated by the pictures of the objects, which become
the means of assisting our recollection, and thus form a durable record
of our visible perceptions; of course excepting motion, which pictures
cannot represent; but motion, or change of place, implies a succession
of perceptions. Yet this manner of record does not directly apply to the
other senses: we can exhibit no pictures of odours, tastes, the lowing
of a cow, the roaring of a lion, or the warbling of birds; much less do
hardness and softness admit of any picturesque representations as their
record. The memory of animals seems to be in the simple state: they
have, through their organs, different perceptions; and in many instances
these organs are more susceptible than those of the human subject. The
ear of some timid species is enabled to collect the feeblest vibrations
of sound, and which are inaudible to us. The eye of some birds can
tolerate an effulgence of light, that would dazzle and confuse our
vision; and others "do their errands," in a gloom where we could not
distinguish. In certain animals the smell is so acute, that it becomes a
sense of the highest importance for the purposes of their destination.
But animals are incapable of recording their perceptions by any signs or
tokens: they therefore possess no means of recalling them, and their
recollection can only be awaked from the recurrence of the object, by
which the perception was originally excited: whereas man, by the
possession of speech, and of the characters in which it is recorded, can
at all times revive his recollection of the past.

It is generally acknowledged that our memory is in proportion to the
distinctness of the perception, and also to the frequency of its
repetition.

The simple acts of perception and memory ap
