This latter arrangement will be found exceedingly convenient and useful for Bromide printing.\nNOTE.\u2014The stop-work is so arranged that the clock will always start when the stop is released, and provision is made to\tprevent any harm\tcoming\tto the clockwork\tthrough the\tstop\nbeing depressed unnecessarily hard.\nThis clock serves admirably for timing experiments where a stop-watch is usually employed, and for many purposes will do as well as an expensive chronometer.\nMost science teachers have no doubt experienced considerable annoyance at the continual breakdowns of cheap stop-watches ; this clock practically overcomes the difficulty, and its price places it within the reach of all.\nThese are already in use in a great number of institutions and physical laboratories.\nPrices.\nS. d.\nClock with\tstop-work and indicator (as illustrated)\t.\t.\t.\t.\t.\t16\t6\n\u00bb\t\u00bb only.......................................................15 o\n\u201e\tindicator-hand but no stop-work\t.\t.\t.\t.\t.\t12\t6\n,, (plain) without indicator or stop-work ......\t10\t6\nAny of the above fitted with gas-burner, as described, 3j\\ 6,/. extra.\nPamphlets of other specialities and catalogues on application.","page":1}],"identifier":"lit13701","issued":"1902","language":"en","pages":"1","startpages":"1","title":"W.
