like modes of force, the apparatus note and record them.

Men are by no means satisfied. Insatiable thirst to know more is
developing into a fever of unrest; they are wandering beyond the limits
of the known, every day a little farther. They survey space, and
interrogate the infinite; measure the atom of hydrogen and weigh suns.
Man takes no rest, and neither will he until he shall have found his own
place in the chain of nature.--_Kansas Review_.

THE FUTURE DEVELOPMENT OF ELECTRICAL APPLIANCES.


Prof. J. Perry lately delivered a lecture on this subject at the Society
of Arts, London, which contains in an epitomized form the salient points
of the hopes and fears of the more sanguine spirits of the electrical
world. Prof. Perry is one of the two professors who have been dubbed the
"Japanese Twins," and whose insatiate love of work induced one of our
most celebrated men of science to say that they caused the center of
experimental research to tend toward Tokyo instead of London. Professors
Ayrton and Perry have for some time been again resident in England, but
it is evident that they did not leave any of their energy in Japan, for
those who know them intimately, know that they are pursuing numerous
original investigations, and that so soon as one is finished, another
is commenced. It would have been difficult then to have found an abler
exponent of the future of electricity.
