d _never_ have
committed to memory such Series by mere _rote_ or _repetition_, and not
one in a hundred could have learnt to say them backwards by _rote_
alone. Yet my Pupils easily learn them both ways, because Analysis
affords the highest possible AID to the Natural Memory. In fact, the
_deepest_ and _most abiding_ impression that can be made upon the
Natural Memory is by impressing it with _relations_ of In., Ex., or
Con.; because these are the Memory-Senses (if the phrase be allowed),
these are the Eyes, Ears, Touch, Taste, and Smell of the Memory: and we
have only to impress the _Memory_ according to the laws of its own
nature and the _Memory_ will RETAIN the impression. This is exactly what
my Art does: for I translate every case of Synthesis into an Analytic
series by supplying one or more _Memory-intermediates_ that grow out of
the "Extremes," each one of which is an instance of In., Ex., or
Con.--Thus, every example of Synthesis is a =developed or extended
Analysis=. To make this translation from Synthesis into Analysis requires
no intellectual ingenuity--no constructive power of imagination--but
only a _recall to consciousness_, through In., Ex., or Con., of what we
already _know_ about the "Extremes." I call a specimen of developed
Analysis a Correlation, because the Intermediates sustain the _direct_,
_immediate_, and _specific_ relation of In., Ex., or Con. to the
"Extremes" (having nothing in common, in principle or nature, with the
old-fashioned Mnemonical "Links," or "Phrases").

1. When is Rec. Analysis used?
2. Rec. Synthesis?
3. How is a revivable connection established?
4. Have you carefully read every question at the bottom of the
previous page, and _thought out_ or written out answers to them?
5. Since questions are valuable helps to the learner, will you
faithfully read all the questions hereafter in this lesson, and
write out or think out the answers thereto?
6. What have the laws of In., Ex., or Con. enabled us to do?
7. Could all people have learned them by rote?
8. What affords the highest possible aid to the natural memory?
9. How are the deepest and most abiding impressions made on the
Natural Memory?
10. What are the Memory-Senses?

EXAMPLES OF CORRELATIONS.

Make your own Correlation (different from mine, given below) between
each of the following seven pairs of Extremes:

[_In._ may be represented by 1, _Ex._ by 2, and _Con._ b
