thoroughly inanimate and inespreseive character of which
fails to eacite either thoughts or foam.
We are at a lore to understand why this Eabibitlos of
Works of Art should take place at so inconvenient a dis-
taste. for the public. A better opportunity of rendscing
the movement he art popular this that which three London
imbibition, afford could net possibly be devised ; but owing
to the out•of-thawey locality they are visit's; by a
very small section of tie eosamanity. Oa Saturday
afternoon last, the most leisure afternoon of the week,
and a fine day, we noticed only a stadeat or two
and a few earriege.folk in the auserous and *whop
room. London is not like Pad', wsere the tailing masses
an enjoy the opportunity of acquiring civilising knowledge,
and of otherwise improving their minds during one day la
the seven. The masses in England are denied this privilege.
G.. eeee meat should therefore avail itself of every means of
meeting this difilealty, by selecting convenient sites for
ea►ibitioaa instituted under its control. Even when these
seams of instruction are easy of access, an inspection of
them on UM part of the shopkeeper, the clerk i+ clic*, the
mechanic, he , is attended in each ease with ezpease ; but
when placed at a distance, as is t►is inflame, an epportauity
of visiting them is denied to the bulk of society. Consider-
lag that the espouse is defrayed by the people, surely
every facility should be given to the public to contemplate
proofs of intellectual progress made at their oast.

ROYAL INSTITUTION.

The leotnre-room of the Royal Institution was
crowded in every pan on Friday evening, to hear Professor
Faraday ezplais the sodas of Iteemeortr's apparatus, by
which the effects of induced electricity are west strikingly

exhibited. Mr. Buhmkorff is • philosophical
maker at Paris, who has contrived by the application of
well•knowa principles, and by • new combination end en-
largement of the ionisation eon, to prcthies from voltaic
electricity some of the beautiful effects of the electricity
excited by the most powerful machines ; and thus to show
most clearly the identity of the force excited by friction and
by chemical 'mien. The apparatus consists of a primary aril
of upper win. round which there is wound a large quantity
of finer covered wire; end by sending a voltaic current
through the first coil, electricity is induced In the second,
though no portion of the voltaic current passes through it.
This " secondary element," as it is called, possums= inten-
sity resembling that axe ted by the electrical machine.
The induction of an intensity current in a second wire was
discovered twenty years ago by Profeessor Faraday, who
sabibited on the lecture table the original apparatus by
means of which that effect was produced. The induced
electricity perceived on making contact with the voltaic
battery is of the opposite kind to that excited on breaking
contact, and Profemor Faraday stated that the cause of
Mere being no observable offset excepting at the moments of
making and breaking contest was that the two opposing
au-cents being equal in force, they neutralised each other.
By • mechanical arrangement, which. those who its
ecquainted with a common medical coil apperatas will un-
derstand, the contact is made and broken automatically with
immense Tepidity, and by this means the two electricities
of the secondary current are separately brought into action.
Ruhoikoff's apparatus is indeed little more than a greatly
enlarged medical coil machine. The flood of electricity
developed by this apparatus was exhibited is many beauti-
ful experiments. When • jar coated Maids with tin-foil was
Placed within the exhausted receiver of an air-pump and one
mid of the mooed wire was connected with the inside of the jar
and the other end with the metal plate of the pump, there
was a copious outpouring of purple light from the interior
of the jar, accompanied by concentrated electric flashes,
which varied in intensity as the strength of the voltaic
battery was increased or diminished. Another remarkable
exhibition of this condition of electric force was its passage
in a succesio• of sparks between the ends of two wires.
The sulks succeeded each other so rapidly se to be not
separately distinguishable when the wires were stationary,
but on moving them about each spark was distinctly visi-
ble; the optical effect, in consequence of the short duration
of the electric spoilt, being the reverse of that when a con-
tinuous light is in motion. Vuions modifications of Ruben-
scoff 's coil have bun made by Mr. Grove end others, to
increase its intensity effects and to mete the kind of elec-
tricity evolved approach still more closely to that excited by
friction. In one of the arrangements shown by Professor
Faraday, in which the secondary wire wax connected with
the interior of • Leyden jar, the positive and negative
slectricities of the sec• ndary current went exhibited sepa-
rately, and producing different. ffeau ; one being intensified
by passing through the jar, end the other being in is ordinary
condition. The sparks emitted by the intensified o. ?rent wens
much more brilliant and made a louder sound than the other,
and the actions of the two currants were also different ; for the
former pierced holes through paper, whilst the letter set the
paper on fire, and the ordinary current ignited gunpowder,
which the other merely threw aside. Professor Faraday
observed, in conclusion, that the extract. Mary pheaomena
exhibited by Ruhmkorrs apparatus open new fields for
discovery, which, if be were • younger man, he should have
eagerly levestigated, and he teamed that other, who had
their minds directed to the subject would be able to elicit
by the observation of thou phenomena many important
truths in electric science.
