We are going to make known to our readers two new styles of electric
lighters whose operation is sure and quick, and the use of which is just
as economical as that of those quasi-incombustible little pieces of wood
that we have been using for some years under the name of matches.

[Illustration: Fig. 1.--MODE OF USING THE GAS LIGHTER.]

The first of these is a portable apparatus designed for lighting gas
burners, and is based upon the calorific properties of the electric
spark produced by the induction bobbin. Its internal arrangement is such
as to permit of its being used with a pile of very limited power and
dimensions. The apparatus has the form of a rod of a length that may be
varied at will, according to the height of the burner to be lighted, and
which terminates at its lower part in an ebonite handle about 4
centimeters in width by 20 in length (Fig. 1). This handle is divided
into two parts, which are shown isolatedly in Fig. 2, and contains the
pile and bobbin. The arrangement of the pile, A, is kept secret, and all
that we can say of it is that zinc and chloride of silver are employed
as a depolarizer. It is hermetically closed, and carries at one of its
extremities a disk, B, and a brass ring, C, attached to its poles and
designed to establish a communication between the pile and bobbin when
the two parts of the apparatus are screwed together. To this end, two
elastic pieces, D and E, fit against B and C and establish a contact. It
is asserted that the pile is capable of being used 25,000 times before
it is necessary to recharge it. H is an ebonite tube that incloses and
protects the induction bobbin, K, whose induced wire communicates on the
one hand with the brass tube, L, and on the other with an insulated
central conductor, M, which terminates at a point very near the
