Submarine Electric Lamp.
An electric arc lamp capable OF effi-
eientfy supplying the needs OF underwater
Illumination for ship salvage and subma-
rine work generally. az well as for opera
tons to be carried on In infiammable or
explosive atmospheres was recently sub

In connection with repairs effected on the
dock gates there, without taking them out
of position. II was found that thorough
examination of the dock gates could be
made by the aid OF lamps. and In order TO
demonstrate its power one OF the divers

lamp itself is double enclosed arc lamp
capable Of giving from l,5oo to 2.ooo-candle
power. the glass gloves of which are made
to stand a pressure Of over 100 pounds per
square inch, while the metal parts and all
joints will stand over 300 pounds. This

Electricity in Healing.
The extent to which many of the latest
medical and surgical appliances depend
upon electricity as an auxiliary to their
convenient and often successful operation
was one OF the most striking lessons OF
the recent Boston convention Of the Amer
lean Medical association. Aside from the
direct remedial applications OF electricity
In the treatment of diseases, says the
Electrical Age, a marvellous development
has taken place In the adaptation OF the
small motor to the mechanical side of the
physicians work.
The whole trend OF present practice
seems to be away from the unnecessary
personal labor Of the manual kind In the
x-ray laboratory. for example, a machine
has been produced for the sole purpose of
rocking exposed plates in trays during the
developing process, which is longer and
more tedious In photographic work than
in ordinary photography. motor Of about
1le horse power does the work. leaving
the man In the laboratory free to attend
to other matters.

The incandescent lamp has been applied
to surgical work In many different
styles and sizes that nothing short OF a
catalogue could cover its field of useful
ness AS an aid in diagnosis and an aux
Hilary in delicate operations in different
parts OF the body. the miniature lamp is
an important accessory.
Electric heaters OF various designs shown
at Boston illustrated gratifying progress
in the application Of this class Of appora-
tus to medical work. One of the latest APP
pliances is an asbestos lined oven for dry
STERILIZATION. in which the resistance ele-
ment Is perforated graphite plate In
stead of the usual wire. An electromasne-
tic switch, actuated by an adjustable mer-
ouriai column. cuts out one section Of the
graphite resistance in case the oven tenn
perature becomes too high.
