Pair of compasses
— how made originally.

Originative material archetype of the abstract
ideas expressed by Geometry, a pair of compasses an
instrument for measuring distances.

First rude mode of constructing them two
twigs, the two ends of these put the one over the other,
and fastened together by a stronger twig driven
through them

This original pair of compasses would approach
more and more towards those formed by modern
art, as the twigs were by scission or friction reduced
near and nearer to the form of the

Two sources of ideas

Formation.

Two sources of the ideas of geometrical figures
1. Observation — hence the original idea.
2. Formation, viz. at first by experiment.

Archetypes by which
the idea of a sphere
may have been suggested.

Archetypes from by which the idea of a sphere
may have been suggested.

The most perfect stones worn into a globular
form by friction in water as in gravel.

Figures not much distant from spheres
are presented by various articles of the vegetable and
animal kingdom.

By the vegetable as nuts, oranges, apples,
potatoe roots and other roots.

By the animal — as eggs of snakes and
perhaps those of some birds.

The idea of a sphere having been obtained
by observation it might presented an by imitative
formation.

An instrument of formation is presented
by the original compasses as above described.
