rowed; her silver Beams, all (he can boaft of, ihe

. en that Side of a Body whereon it is shadowed, that
is to fay, from that Side turn'd towards any opaque
Place or Body, as Groves, Trees, Herbs or Plants ;
for though every Bough and every Leaf, admit of
Light, yet the yaft Number of Boughs and Leaves
conftitute a dark Body, through which the Rays of
Light can never enter.
The Reflexes of Light are brighter, or less appa-
rent, according as the Ground on which they are
difcern'd is more or lefs obfeure: When the Ground
is more dark than the Reflex, the sormer ferves as
a Foil to the latter, and the Ressex will appear
strong and apparent: On the other hand, when the
Ground is brighter than the Reslex, it muft naturally
appear more gloomy, by the Luflre that furrounds
it, and by which means it can scarcely be difcern'd ;
biit that which is vifible on the darkelt Ground must
^appear the boldeft, and moft plain ; cn the other
hand, that on the brighten: Ground muft be lealt di-

against the other, the fuperior Whitenefs reflects a
