To illustrate how little exact knowl-
edge of principles will prevent errors IN
painting, observe the veins on the back
OF your hand and arm. As your hands
rests below the level of the shoulder
ordinarily these veins will be prominent,
at least in man. Now raise your hand
slightly above a right angle with the
body and note how rapidly these blue
lines disappear. You could not have
foretold such an occurrence, nor would
YOU have been likely to have known of
its possibility if uninformed of the phys
i0ogy of blood circulation. The
arteries which lie deeply and out OF
sight carry blood from the heart to the
eAtrcmities; the veins, nearer the sur
face, and iCnce often visible through
the skin, conduct Tie flow back TO the
heart In limbs below the level of the
chest the current is against gravitation
and the veins become prominent through
distension. When, as by lifting the
arm, gravitation assists the flow back to
the heart the blue channels are seen no
longer because rapidly emptied.
An otherwise excellent picture was
marred by prominent veins being repre-
sented upon an uplifted arm, and this
error was carried to an extreme in
picture of Mercury with arms extended
in downward flight. the feet being
uppermost. Tho artist had faithfully
copied from an upright nude, and in IN.
verting his canvas thought he had salts
fled all the conditions, whereas the leg
veins were visible when they should not
have been, and the arm veins were not
to be seen when the pictured position
should have made them prominent.
Without anatomical knowledge no one
could account for the sinking in of the
knee-cap when the leg is bent. Nor
would one be aware of such matters as
the knee-cap, or patella, of the female
pointing forward, while that OF the
male turns outward, the arm pit proper
existing only in the male, and that in
adults, and not in children, of the oppo-
site sexes, do differences in widths Of
hips occur. s.
Many mysterious effects are brought
about in very simple ways as may be
realized when reasons are apparent. For
example, when the arm is bent the ole
cranon or crazy bone" presents bony
prominence in view, but owing to the at
tachmcnt of the cuticle to this point
dimple is produced at the elbow when
the arm is Strengthened, especially when
there is freshness" of the member.
I have known otherwise fair artists to
be unaware that the palm of the hand
was concave and the back thereof con-
vex. Few observe that the webbing be-
tween the fingers lies closer TO the palmar
than to the back or dorsal surface, and
that the tendons of the wrist are invaria-
BILE and after an orderly plan. p
A picture maker with the same want
of astronomical knowledge of Charles
Dickens would have made the same
error of describing star as shining be-
tween the horns of new moon. re

pie the law of relatively should have due
