• ELL CTRICITY .

M. Faye has addressed a curious communication to the
Academy of Sciences on the effects of metallic vapours on
the stratifications of the spark from Ruhmkorff's machine
(called spark of induction) "i n vacuo." Suppose a receiver
filled with oxygen, and traversed by two rods opposite to
each other, and connected by a thin iron lamina shaped
somewhat hollow in the middle. In this hollow a piece of
sodium is placed; the air pump is brought int) action, unit
then, by means of a voltaic current, the iron lamina is
brought to a white heat; the vapours of sodium instantly
fill the apparatus and absorb the oxygen it contains. As
Sodium emits no vapour at the ordinary temperature, the
excess of vapour produced at a white heat will deposi
itself on the sides of the receiver in the form of a
powder, leaving a vacuum for subsequent use. M. Faye,
being desirous to ascertain the effects of the vapours of
sodium on the spark of induction en mem, placed the- ap-
paratus in communication with Ruhmkorff's machine. No
sooner was the lamina of iron raised to a white heat, than
the stratifications of a vinous rose. colour which characte-
rise the positive pole were changed into yellow, while the
blue light of the positive pole was divided in two, being
strongly repelled right and left, and assuming a greenish
hue. This part of the spark of induction presented trans-
versal stratifications, that is, in a direction perpendicular
to the rheophores. As soon as the voltaic current ceased
to keep the lamina at a white heat, the spark of induction
returned to its usual form of a rose-coloured spindle.
These experiments have been repeated with zinc, which
changed the rose-coloured spindle to blue; with antimony,
which changed it to lilac ; with cadmium, which produced
green; with bismuth, which produced various changes of
colour; and sulphur, besides giving a blue colour, divided
the fusiform name into two distinct and equally fusiform
parts.
