some recent tests have brought TO
light tho fact that iodine occurs in GER
tain articles OF human food in small
quantities, and as IL occurs in fab
and shell fish, IL has recently been
suggested that this fact may be the
reason why fish is so valuable q food
| for invalids. Traces OF iodine have
been found in codliver oil, and il is
possible that it, together with the
bromine and phosphorus, contributes
to its tonic effects.
Light travels tully 5000, 900, 900,
600 miles in a year, and even the most
modest guesses as to the parallax Of
Polaris make it thirty-fve light years.
Pritchard's estimate in / 887 was ninety
his figures. Hence, " one will write
two hundred and ten and add twelve
ciphers thereto he will have the mum.
Der of miles which the most conserva.
tive authorities believe intervene be.
tween the earth and the pole star.
The deep sea is in total darkness,
and plant life, according to Sir John
Murray, is quite absent over ninety
three per cent. of the ocean bottom.
Fishes and invertebrates, however,
are scattered over the floor OF the
ocean at all depths. The majority Of
these deep sea animals live by eating
the mud, clay or ooze, or by catching
the PARTICLES OF organic matter falling
from the surface. 1t is probable that
three -fourths of the deposits now COW
ering the floor OF the ocean have passed
through the alimentary canals of
marine animals.
From a recent investigation on the
influence OF pressure on milk, il ap-
pears that milk under pressure OF
ten tons could be shipped five or
ten days journey without fear of
spelling, but the cylinders capable OF
carrying such pressure would prob.
ably weigh more than the milk. Great
pressure applied for short time
greatly delayed souring. After a
pressure of thirty tons for eight to
twelve hours, milk will usually keep
sweet three to five days, and after
pressure OF forty tons at 1875 degrees
Fahrenheit for an hour, meat kept in
good condition Tor three months.
DIR. f. w Scripture described be-
fore the American Association for tho
Advancement of Science the method
of producing an @sthesia by the di-

rent without the application of drugs.
An alternating current with equal
positive and negative phases was made
to traverse the nerve. At proper
frequency Of about 5000 complete
periods in second it can be made to
cut off all sensatory communication
by this nerve. Needles can be run
into the part Of the body supplied by
this nerve without any pain being felt.
As to the distance of the present
pole star from the earth, it nay be
mentioned that its light requires about
44.6 years to reach the earth, notwith-
stading the fact that light dashes along
with such inconceivable speed that il
will cover 1S5, 900 miles per second.
The light from Vega, the next pole
star, requires eighteen years to ira.
verse the distance between it and the
earth. AS a consequence, we do not
see the present pole star as it is at the
present time, but as it was A. 6 years
ago, Indeed, if the pole star were
blotted out from existence to-day, it
would still continue to shine out as
vividly as ever for 44.6 years. So it
is with all other stars, according to
