A Mr.. RoFER gives the following rule
for finding the safe working pressure of
steam boilers: Multiply the thickness
of the iron sc if singie-rivited, ai2d 20
if double-rivited; multiply this product
by 10000 (safe load); then divide the
last product by the external radius less
thickness of iron); the quotient will be
the safe working pressure III POUNDS, per
square inch. .
PROFESSOR TYNDALL, in his late ar
ticle, says that the emotions of man are
older than his understanding, and that
the poet who brightens, purities and ex'
ats these emotions may claim a position
in the world at least as high and well as
sured as that Of the man of science, be-
cause he ministers to different and
equally permanent needs of human ma
ture. The man of science, he thinks,
will never be able to destroy the glory of
the lilies of the field
MADLER announced his belief that
tIcvone tie cniUt star of the Pieiades
Cthc Seven Sisters), vas the centrai star
of the universe, which led men 10 think
that the stellar system, like the solar
system, Ieyo.yes round q center. The
only evidence Nader bad for this opera
ton was the drift Of the stars of the con-
stellation Taurus IN enc direction. This
has since been proved to be no evidence
as similar drifts have been observed III
either directions Mr. Richard n. Proc
tor now comes forward with his opinion
that the whole theory of p central sun -
a myth, and not supported BY any khOwH
astronomical fact.
PROFESSOR GEONEMAN, of GOttingen
has prOpUunded theory of the aurora
borealis resting on the presence Of masses
of iron-dust in the polar regions: Polar
snow has been found to contain partic es
of iron, evidently prccipitated from the
atmosphere, and it is Groncman's sup
position that these masses or particles
describe path round the sun, and when
the earth crosses it, particles are attached
by it, and more especially by its poles.
Being carried swiftly through the atmOs,
phere, they ignite by fric ion against it,
and so become luminous, as is the case
with meteorites NordenskjOld has
found metallic iron, cobalt and phOs'
bhorus in snow north Of Spitzbergen.
