SCIENCE AND INDUSTRY.

A French physician, Dr. HervieuN
has made Investigations which indi.
cate that flies spread smallpox.
Fish are great glattons. That is
probably the reason why fine look ng
bait tempt so many of them to de-
struction. A single bluefish has been
known to kill and devour 10 cod each
as Big as himself in rapid succession.
1t Is stated that an electric locomo-
tive used In Canadian coal mine
shows saving over mules Of 252S in
200 days. and an electric pump ope' a.
ted in the same mine shows assaving
over steam pumps of S1513 In O70
days,
Very small PARTICLES of Water have
tendency to fall slowly In still air,
while Il very light upward current
VIII be eHough to keep them from de-
scending ut all In the case of very
small particles. 1t has been shown.
that the globules of water forming q
fog or cloud are ench composed OF a.
film of water condensed ,ipon d Rartl-
Gle Of dust, ahd the cores are solid In
stead of gaseous, as the Old theory in.
dicated.
The Pharmaceutical Era emphasizes
the use of milk as universal anti.
dote applicable to most: cnseB Of pos
soning. By its fatty matter and its
casein it protects the muc0ds mcm-
brnne Of the stomach against the cor
f6sive action Of acids, alkaline and
other caustic or irritant substances.
The addition of small amount of
borax Is also useful. as this induces
absorption Of most Of the mineral
poisions. If arsenic Is suspected
uagnesIa should be given.
The greatcst heat produced artih-
etally is that of an electric arc furnace.
the kind that Is used In the produc-
ton of artificial diamonds, calcium
carbide, etc. 1t Is go Intense that
nothing exists with which to record 1t.
1t is estimated, however, to be Of about
1000 degrees. The coolest known
temperature is that Of liquid air,
which freezes alcohol and mercury. and
distances all means Of measuring. 1t
is claimed that with it temperature
of 400 degrees below zero Fahrenheit Is
reached. The present limits of heat
and cold are, therefore, representa- by
the arc furnace and liquid air.
A Portuguese inventor has patent
ed an application of the electric light
to fox and badger hunting. The fox
and the badgar are animals that live
in dens underground, md terriers and
other kinds of dogs are used to d'g
them out Of their burrows or to tight
and kill them underground. The IN
genious Portuguese conceived the idea
of attaching an electric lamp to, the
collar of the dog so as to light the way
for him in his descent into the hole,
and Of making the light colored SO as
to scare the animal and cause it to
rush forth to Its destruction. A pat
ent upon this scheme has actually
been granted.
One Of the most promising papers
read before the recent annual meeting
of the British Iron and Steel institute
was that Of q. ]. Stead, which showed
the possibilities Of the miscroscope In
diferentiatlng the ingredients of steels..
Hitherto the usual process of m.scro-
scopic investigation has been to pcli b
the sample and then etch 1t with acid,
or some other solvent. But the new
method he described the polished spaci-
men Is heated until 1t shows a purple
color to the naked eye, due to TIM
layer of oxides When this colored SUR
face is examined under the microscop,
It will be seen that the various con-
stituents have each taken on differ
ent hue, that due to its oxide, the
phosphides being distinguishable BY
their light yellow color. The obser-
vations made Dy this process are sad
to have been remarkable justifcations
Of the solution theory Of Iron.
