Exhibit the solids
natural and artificial,
from whence the ideas
of the several abstract
fictitious entities, boundaries
of those same
solids, may have been
deduced
20 7. For facilitating the keeping in memory the
conceptions formed of the various superficial figures
exhibited by the several Geometrical entities provide for
the inspection of the learner samples of the several physical
and real existing entitiies chiefly solids from which the
ideas of the several geometrical figures may have been
derived.
20(a)
1. Stone dropt in
water shews a circle
Note (a)
(a) Say chiefly solids: for one superficies there is from
which the most familiar of these figures cannot but have
been derived this is the circle: — a figure which
presents itself to view as often as a stone or any other
solid body is thrown or drops into the water.
2 Path of any body
falling shews a line
Another figure in some sort analogous is that
which is presented to view by the path described by a
stone or any other solid body convenient for the purpose
when on being thrown in the air it reaches the earth.
3. Form — — shewing
solids are
1. Natural
2. Artificial
The solids in question will have been either — 1.
natural or 2. Artificial: but to the mention made
of the artificial on this occasion it may be objected that
having been made by the hands of man they cannot
any other of them have served for primordeal
archetypes thus for instance in case of a pair of dice
it cannot have been by a die that an idea was first
given of the solid called by geometricians a cube.
4. Form shewing
natural solids, common-
salt
crystals: correspondent
artificial,
dice.
Instances of natural solids, by from which may have
been deduced of the correspondent geometrical solids
with their several characteristic surfaces, are the
following
From the crystals of common salt, the cube: correspondent
artificial solid, the die.
