The report from a French source that
Lord Rosebery. Foreign Minister. has
quarreled with his chief, Mr.. Gladstone,
may be set down as an absurdity. If
quarrel were 10 arise between statesmen
who are the best of friends the news would
come from a more likely source. Why
should they fall out? What turn of policy
has arisen on which they should differ so
Numerically that there should be break
in the Cabinet? Su rely not foreign Affairs,
with which Lord ROsebery is most con.
cerned. AS to home rule in Ireland. the
Foreign Secretary is supporter OF the eX-
pertinent, for experiment 1t Is. and Is
hopeful Of the best results, but not COCK
sure Of what all those results will be. LIZ
there were any cause for change 1t would
be from R0sebery's bad health de is said
to suffer much from insomnia, and II was
understood he took Office this time little
unwillingly. But once statesman is
prominent it is difficult 10 withdraw. His
friends perpetually tell him he has duties
to his country, and his opponents compel
him to think that he has. Private lie
thus becomes humdrum to the man oil
often means wasteful occupation IN horse
racing or other forms OF sport
Faraday's remark, when asked about
the use of apparently useless researches.
what is the use Of baby?" is shown to
be philosophic by the results now spring
ing from the successful liquefaction and
even freezing of air. We are on the high
road to learn a great deal more about the
nature and properties of molecules. with
a low temperature of 100 degrees cent?
grade. approaching absolute zero, Profess
sor Dewar of the Royal Institution has es-
tablished that at the lowest attainable
temperature all metals have the same de-
gree of conductivity of electricity. They
differ greatly at high mperatures, but
are on an equality far down in the scale.
Professor Gladstone's theory OF the refrac-
tive indices of gases has been confirmed.
By means OF vacuum pump Ii IS possible
10 freeze liquid air (nitrOgen aud oxygen),
but thus far it las been found i'm pOsSible
TO freeze oxygen alone. The moment the
pump stops action the atmos pheric ice is
again LIQUID. The cohesion of metals is
wonderfully increased by iutanss cold. 1t
is found that the tensile strength of iron is
doubled at $50 degrees centigrade compared
with the strength of Is degrees centigrade.
A magnet which is fully saturated has its
power increased so per cent. Even color
changes. The scarlet of mercury iOdide
when spOnged with liquid air changes to
orange, but gets back lis hue when heat
returns. When electricity Is sent through
vacuum globes subjected to intense cold,
all the phenomena of ph9sphorescence dis
appear. The electricity seeks any route
but the ordinary one through the globes.
Something is frozen out which causes the
vacuous space TO be stunned.
Two shipwrights in one of the English
Government dockyards are said to have
invented an automatic method of closing
all the water-tight doors on vessels of war
simultaneously. The plan Is under official
examination, and it will be miracle if it
is not shelved or appropriated by some
superior person. as often happens with
patents. The value OF such an invention
is apparent. Had there been automatic
closing of the doors on the Victoria, that
Inflated vessel would not have foundered
with hundreds of brave men. The prin-
ciple Of the mechanism has not been ex-
