The possible effect of electrolytic
corrosion on the anchorages Of Brook
Ign bridge is not viewed as an imme-
diate danger by the New York journal,
Electricity. Discussing the predic-
lions of an electrician on the subject
it says: We do not agree in every
por rt1o,r with tlo-~inu-e, Of tho CON
tleman just quoted, nor do we think
the Brooklyn bridge would be likely
to fall in 20 years, for in order to de-
stroy 91a tons of metal year by cleo
trolytic action all the conditions would
have to be most favorable. Neverthe-
less, as the exact progress made by
electrOlytic action cannot be very we'll
aScertained, owing to the inaccessible
ity of the anchOrages, it behooves the
authorities to take some action, and
that speedily, to divert any stray cur
rent from the cables. This could be
done without an enormous expenditure
of money, and would set at rest once
and for all the periodical cry us cleo
trolysis destroying the Brooklyn
bridge?"
No other physical measurement,
says the New York Sun, is in such a
state of confusion at present as that
of light. The familiar term candle
power, as applied to electric lamps,
for example, means half a dozen diff
ferent things according to the various
ways in which the measurement is
taken. For example, an ordinary in
candescent lamp, which may give 16
candle power in direct perpendicular
to its axis-side on, that is-rarely
emits more than 10 or Il candle power
Of light from it's tip or bulb end, and
gives absolutely no light in the direc-
ton of its base, which casts a shadow.
If the lamp is supposed to be sur
rounded by an imaginary sphere, the
average light over this is called it's
horizontal candle power AS nearly
all incandescent lamps are installed
with the bulb downward it is evident
that the most important part of it's
light is that which shines out through
the tip end. Recently it as been found
that using a filament coiled into a
spiral of three turns greatly enhances
the illumination in a vertical direc-
ton. This, with a new method of
making the glass bulb which leaves it's
lower end free of the tip, is believed
to constitute an important advance in
the art of lamp-making.
An electrical sanitarium is proposed
at st: Louis. Says DR.. Hobart Ro-
| barts, who is at the head of the ven
ture: The hospital will be as nearly
battery in every corner and crevice
as we can make it. It will be fitted
with every kind and variety of cleo
trical apparatus that has anything to
do with the generation of currents.
The expenditure Of a large sum of
money will be necessary to provide us
with these appliances as all of them
are of the most delicate order, but
we will be able to command the funds
needed. The hospital will be a thor
| oughly legitimate institution. It will
! not be operated on cure-all basis
| We will simply take patients and
treat them, obtaining the best results
we can. 1t will have a staff of assist.
ants and they, like myself, will be reg.
ular practitioners of medicine. who
| have devoted special attention to cleo
trlclty as a therapeutic agency. Our
plan is to devote special consideration
to chronic troubles that cannot be
treated properly in the old way.
