5. Key functions
1. Geometry
or 4
Examples of such
Keys may be from in the
works of Mathematicians:
[the more
such keys, the more
instructive the work
to learners: however,
it may be as to discovery
and advancement.

Of the sort of instrument of elucidations, for the designation
of which the word key is here ventured to be displayed,
-played happily for the and the learner and the itselfexamples are not even more, are not altogether
wanting in the works of mathematicians: (and to as for the
as concern purpose of instruction at least, howsoever it may be in
regard to further discovery and advancement, it will
scarcly be denied but that the greater the number more of those keys, supposing
them equally well constructed, as that the wish affords
the better adapted it is to its purpose.

AnOne example which of itself is worth a multitude, may
be seen be id afforded by in his Histoire des Mathematiques
Tom 1.L.III. Note B.p. Tom 1. p.197 to 201.

In it the several those peculiar figures, three in number capab le of being produced [+] the principal than
by the cutting if a cone (or rather a pair of cones)
are brought together are confronted with each other, and
the their principal characteristic properties by who in respect
viz. those in which they agree with and those in which the
differ from each other, are brought placed together in one view to view: all in the
compass, of form no more than though its merit to acknowledgement closely

Comparative view of
the three Course Sections
Here, too the enuntiative
parts alone
(as above proposed)
are presented, without
demonstrations or preparations
to do
Definitions, 6:
Preparations 21:
Multiply by 3
Number of the Con
Sections, total 63
though all 3 are
not in everyone

What A circumstance which renders the example the better adapted to the
present purpose is - that on this occasion nothing more is
given than the enuntiative parts of the several propositions,
preceded by such definitions, no more than six in
number as were judged necessary. Total number of proposition, according to the numerical figures no more than 210 21: though if it be considered
that in most of them the three sections species of plan Cause
Sections in question are comprized, that number may
in that respect be required to be nearly tripled.
