tion; experience shews us, that it is possible the
same object may be felt with the same sensation
of motion, along with the interposed impres-
sion of solid and tangible objects, attending the

and intangible distance may be converted into
a visible and tangible one, without any change
on the distant objects.
Thirdly, We may observe, as another rela-
tion betwixt these two kinds of distance, that
they have nearly the same effects on every nat-
ural phaenomenon. For as all qualities, such
as heat, cold, light, attraction, &c. diminish
in proportion to the distance; there is but lit-
tle difference observed, whether this distance
be marled out by compounded and sensible ob-
jects, or be known only by the manner, in which
the distant objects affect the senses.
