Preece famous electrician in the English civil

batteries of great importance III its appicat ons to
electric lighting and the other On domestic stems

in form and were delivered most effectively, Mr..

Matthew Carpenter described a house In scotland
lighted by electricity. Through the ground, ran Il

lean turbine wheel and conducting wire circuit
of ninety lamps was established. The owner of the
house had lamp at his bedside. which he could
Hsht at any moment and he could also control by
another key the water supply OF the place. This
man had not found the system expensive and II
had worked most satisfactorily. Another house
holder not having water power on his
grounds had to use gas engine IN
generating electricity, bnt nevertheless he did not
consider IL an expensive luxury.
Sir Frederick Bramwen described Mr. Precce's
house IS a model OF comfort and luxury III respect
10 the method of lighting IT, and predicted that the
DELAY in developing the system caused by vicious
legislation in England would ultimately prove
decided advantage since an improved apparatus
would be used.
THF ELECTRIC RAILWAY.
After Mr.. Preece had explained that be used a
gas engine and a secondary battery in generating
electricity and that be hoped to be able 10 store
enough energy TO last single week, a new topic
was introduced in the electric railway now
operated near the Giants Causeway, Ireland. Dr.
