LONDON Times, June 30th.
M. Jablochkof, who was the first to in
troduce electric lightning in our midst on
practical scale, has for some time past
/ directed his attention to the production of
electricity by means of a primary battery.
lie at first produced sodium battery,
which developed very high electro
motive force. 1t had, however, one radi-
cal defect which married its success, and
that was the rapid oxidation of the sodium
in contact with the air. M. Jablochkoff,
however, has succeeded in developing
from his original idea battery which is
at once novel and unique Having re-

stration by NJ. Jablochkoff of the battery,
We are enabled to give some particulars
OF the latest as well as most interesting
outcome of electrical science. The auto
accumulation, as it is termed, is composed
OF a series of cells, each of which has
three electrodes, and the battery is dis
tinguished by its lightness, its small cost,
its power relatively to size, its freedom
from smell, and the absence of liquids
otherwise than in an absorbed condition.
The battery is composed of num-
Der of cells or shallow trays four
inches square and one half inch deep,
OF impermeable carbon, in each of which
is placed a small quantity of iron turn
ings or zinc clippings. Over these is
placed a covering of thick, coarse canvas, ),
saturated with solution of chloride of
calcium, upon which is laid a row of very
porous carbon tubes about three inches
long and thre-eeighths of an inch in di-
ameter outside, which are similarly sat
urated. In this way cell is formed
with three electrodes, one of which oxi-
dies, a second becomes polarized, and
the third forms a positive pole with the
second, the two first forming couple
with a constantly closed circuit For
service number of these cells-nine or
ten-are placed within metallic framing.
after the fashion OF a. voltaic pile, the bot
tom cell resting on metal plate forming
one of the poles. The top cell is covered
with plate of carbon to which termin-
al is fixed, and this forms the other pole.
The auto-accumulatOr produces alternate
ly primary and secondary current,
the latter only being employed in the ex-
ternal circuit, while the former serves to
produce the hydrogen necessary to polar
ize the electrodes. This action stops as
soon as polarization is complete, and is

so that short and frequent intervals of
rest are necessary for the battery to re-
form itself for the production of the use
ful current. In practice, when this cur
rent is employed for continuous work, the /
batteries are coupled in groups with |
commutators, so that no interruption in
the current takes place. In the recent |
demonstration, at which several promin-
ent electricians were present, Nj. Jabloch- |
kof explained the principles of the inven-
ton, and demonstrated satisfactorily its |
power by driving in turns some Swan
glow lamps and an electric motor, thus
its practical application. We

Jablochkoff's invention in Paris, where
the batteries are being manufactured and
are coming largely into use 1t would
appear to meet the objections present in
most primary batteries without having
any of its own, sol far as present experience
has shown.
