AS to the periodicity of the maximum
and minimum Of sun spots Prof. Young,
of Princeton, discards the hypothesis
which ascribed it to planetary influence,
and deems its more probable that the
cause is solar-that the forces in the sun
accumulate and, rs it were, boil over at
recurring periods with the same irregular
regularity as the spouting Of geyser.

For O standard of light NJ J. Wolfe
takes rs his absolute unit the radiation
emitted by a square centimetre OF plati-
mum at it's point of soliditication, the in
tensity of which is about equal to II
Carcel lamps. MN. E. Mascart, F. de
Nerville. and r. Benoit conclude that
the value of the ohm is represented by

millimetre in section and 10633 MILL
metres in length.
Silveroid is the trade name given to q
new, close-grained, brilliant, white alloy,
regarding the composition of which little
is known beyond the fact that cadmium
enters into it. It is intended to take the
place of the brass, bronze, and gun
metal classes of alloys, and if all turns
out to be true which is spoken in its
favor it will soon do so, especially in the
manufacture of articles which must be
strong and capable of taking fine
polish.
MN. Depierre and Clouet have seut in
a communication to the Chemical Sec
ton of the Industrial Society of Null
house on the action of the electric light
and of solar light upon colors printed on
cotton. They conclude that the electric
light bleaches coloring matters; the COL
ored rays of sunlight and of the electric
light both being efficacious, though in
different degrees. The action OF light,
solar or electric, is recongnized, whether
the colors are exposed to or protected
from the air, and the activity of the rays
increases in the following order: Vel

N. A. Livache has ascertained that an
ordinary drying oil containing lead dries
in "a hours, but q similar oil containing
manganese dries under the same condl-
tons in from to hours. Copper, zinc
cobalt iron, chrome, ETC., prolong the
time of drying to SO to AZ hours III
practice Livache takes an ordinary lead
oil, adds to it dry manganese sulphate IN
fine powder, and agitatcs the mixture
for some time in the cold. The man
ganese is entirely substituted for the
lead, and the oil obtained freed from
drexs. by simple decantation possesses
an exSrcme drying power.
