any kind Of stuff that may carry nine
ty-six per cent. fine copper. and much
OF the visible supply consists OF mate
rial carrying obnoxious impurities.
Should some high grade bars be found
in stock premium Is paid for them.
AS high as thirty shllllngs' premium
has been paid for CS--e bars recently.
Standard copper is the speculative ar
ticle and under an ordinary contract
the seller can deliver any quality OF
bars. provided they contain ninety-six
per cent. pure, hence the premium paid
for choice brands.
There is so great a contrast between
birds and animals in two OF their most
important senses that field workers ind
il a matter OF never-ending wonder.
The birds have sight, but no taste or
smell. The ground animals have the
power of scent. but their sight is rela-
lively poor. The birds keenest sense
is sight. The eagle looks down from
the clouds and sees the snake crawl
ing along the ground. but the snake
never sees the eagle until il Is com
PEELED 10 strike in self-defense. The
sight of the falcon is even keener than
that Of the eagle, and the common
yulture is remarkable for its vision.
That high attitudes have a favorable
effect on quality and number of the red
blood-cells is the result of the observa-
tions of L. Abderhalden. In going from
lower TO higher attitudes the number
Of red blood-cells increases; likewise. in
descending from a higher TO a lower
altitude the number of red blood-cells
diminishes. The same rule applies
10 the quantity of hemoglobin. The in
crease takes place Immediately, and re-
mains constant during the entire stay
at the higher altitude, but the decrease
accompanying descent takes place
gradually, until after four 10 six days
a constant number Is reached The
hemoglobin and the red blood-cells rise
and fall in the same degree.
In several London hospitals surgeons
are now using the telephone whenever
they have occasion TO probe for bullets
or other metallic objects. The receiver
of the telephone is placed on the head
of the operator, and the patient is
placed, in the usual manner, in con-
tact with a plate, the general medium
employed being a wet sponge or some
paper saturated with a saline solution,
which is spread over the plate. The
latter is connected with the telephone
by a wire and the probe, after IL has
been introduced into the body. na;ur-
ally vibrates as soon as the foreign
metallic substance comes in contact
with It, The probe is also connected
with the telephone by q wire, and thus
no such blunder is possible. as some
times happens when an ordinary bat
terry is used. ,.......rr, t'+,,'.irl q .sAs.

with reference to exploiting its mineral
products. There is, il seems. plenty
of water power in this section. and
il is suggested that as smelling can
now be carried on by electricity. these
water powers may solve the problem.
II the ores are as rich as they are
claimed TO be. it is possible that they
could be profitably transported TO the
coast and shipped 10 other countries
for refinement. Lack of transporta-
tion facilities has hitherto prevented
this experiment. Manganese deposits
are quite numerous, and are already
being mined to some extent.
