siliation of each other; but, if the direction os
the light be in the same plane as the walls sup-
posed, it will shine between them, and thus
part them : or, if the shadow os one falls upon
the other, it will equally imply a separation
between them.
When a shadow is of considerable extent, the
objedts which are immersed in it, are not en-
lightened from the same quarter as the objedt
casring the shadow, but by ressexions from! the
opposite quarter; so that, the lights and sha-
dows are situated reverfely. If a person Hand
under the shadow of a high wall, which shadow
falls to the left, he will receive a ressected light
from the left, and cast to the right a fnadow on
the wall, against which he Hands : always sup-
posing no impediment to be interposed, but
the air to be free.
Ressedtions are very much consused and in-
termingled by partaking of luminous rays
emitted srom other bodies; and especially, if
the ressecting objedt be near the shadow, it
very strongly enlightens it: as that Lady’s
white dress ressedts so clearly on the shadowed
ssap of the table, as to whiten the shadow.
These particulars, and many others which
are allied to them, are by no means proper
subjedls of perspedtive regulation ; they must
