House.

Although however, these general aspects of
the radiance suffice to determine the general
aspect of the building, yet a closer investiga-
tion of the light will disclose a more intimate
relation. For since our atmosphere may be
conceived as divided into successive layers of
air, increasing in density as they approach the
earth, each ray as it travels will be slightly
deflected, or refracted, as it passes from a finer
to a denser ring, the refraction being greatest
when the body is on the horizon, and imper-
ceptible when it is near the zenith. Conversely,
if on any given day the position of the sun be
observed at ecpaal intervals from rising to
noon, and from noon to sunset, the apparent
place of the sun will, owing to refraction, be
slightly different from its true position at any
