hot eudeavor to surround ourselves with
beautiful faces as wells Can there be more
enjoyment in regarding chair or dish than
iu looking into the face of mana
see one enthusiastic about work of art
The next day. hear him say he cares not
now man looks, provided he has brains
How far is such a one from unders standing
the true mission of the beautiful.
Intellectual strength and goodness are
beauty OF one sort; personal charms of an
other. The one is beauty latent, ready to
take form at any moment; the other beauty
living, shining in every place and at every
minute. Both serve a common purpose:
tnat OF making life more happy because
more fuli OF beauty. Let US then have the
sauteous mind in the fair body. n
Inc documentary system consists of the
sSn, hair, halls and teeth. 1t may seem
strange that the latter should be included
under this name. But during the develop
ment OF the organism the teeth are derived
from the same structure as the skin The
lntegument Is divisible into two PORTIONS
tue SKIN proper or "true skin" " and the
cutcle or " scarf-skin." The cuticle simply
forms thin cover for the true skin. 1t is
composed of several layers which grow
more hard and scaly as they approach the
surface. The uppermost stratum Is being
continually worn away, and its elements re-
paced as continually by new ones from be-
low In one OF these layers of the cuticle IS
Iound the pigment of the skin This exists

but is particularly abundant in dark races.
The true skin is made up of hbrous tissue,
quite dense IN texture near the cuticle but
hoser IN the deeper portions. 1t sends a
great many fnger-like projections called
papllls up into the scarf-skin; in these re-
sides the sense Of touch.
Under the true skin lies the common con.
nectve tissues Of the body. 1t is in this
latter that we find embedded the long hairs
and the sweat glands.
a hair has a root, shaft and a point.
Ihe root is the little whitish portion seen at
ihe end Of hair when it is pulled out 1t
ndged in little pit In the skin called the

projecting above the skin. Nearly all the
0sMrMg matter is present in the shaft, the
aul'uat and kind of pigment determining
'ue eonr OF the hair. The point of hair is
suoUlaer and finer than that of the finest
