Synchronised Clocks


    RAILWAYS, among many other services which they have rendered, have made us more particular about keeping our watches and clocks in accordance with some common standard of time, and during the past few years various systems have been tried for the distribution of a standard time from a common centre—in this country Greenwich Observatory. For purposes of public life it is more important to have all the public and even private time-pieces of a country set according to one standard, than that they should show the correct local time. The latter can easily be ascertained by any one who desires it, if he can be sure of knowing the exact Greenwich time. Of all the systems that have been tried for ordinary public use, that recently organised by Messrs. Barraud and Lund, of Cornhill, seems to us to answer all the requisite conditions. We had the pleasure the other day of inspecting the arrangements made by Messrs. Barraud and Lund for the distribution of Greenwich time from Cornhill as a centre, and we are bound to say that the perseverance and ingenuity displayed deserve success, and we believe that wonderful success has been obtained. Messrs. Barraud and Lund have spared no pains and no expense to perfect their system, which, as a practical and widely useful application of science, is full of instruction.
