The idon of utilizing electricity as n meaus of maiutnining nniformity and regnlarity between ijublio clocks has beon put iu practice íor some timo, bnt tlu' diliiciilty is that the systrm is flot automatie ; Üiat is to say, some seeond agem-y is roquired ia order to apply the information brouglit by tolegraph to tl' corrèction oí tlie clock. An Austriau engipeer, Herr Mnyshofer, has hit upou tho expedieut of pneumatio tiibes, whioh are laid down along tlie stroets, and can lic bianohed oif in any diroction. I?y means of the force thns omploycd tlie hands of the various clocks nin be moved forward at intervals of n minute or half minute, in accordunce with tlifi time indicatcd by the standard time-pieues in the observutory, so that exact uuiformity can lie maintaiiied without difliculty in the time shown on any tumbar oí dials. In thla w;iy the neoeseity for separate time-ineasuring nppnratns for ench dial is obviatt-i!, añil by ;i simple contrivauce, soiui wli:;t similar to that whieli sets "pnenmatio bella" ringiug, the hand will simply be nxged t'orwird at dèflnite short interval.
