at laft, the further parts are greatly concealed by
the nearer parts: or, at leaft, they appear reced-
ing, and, as it were, flying off.—This is evidently
an effect of Perfpective ; but this is reducible to
no laws, whofe application is determinable, fmce
what may apply to one member, or to one attitude
of a member, may not fuit another member, or an-
other attitude.
Forefhortening is, perhaps, of the greateft confe-
quence, where, only, this flying off, or receffion, is
to be reprefented : and fuch inftances are perpe-
tually occurring; no attitude can be without them
in fome of its parts : the principle runs through
every member of the figure, and, according to the
dimenfions of a member is more, or lefs, apparent.

fingers are forefhortened in fome refpect, or other,

imitation of this effect, befide accuracy of outline,
the application of that retiring (hade we have no-

influence in moderating the brilliancy of the parts
forefhortened, it feems to increafe the vivacity, and
the force, of thofe where the light firikes; as, the
