| 10 THE ELVERSON The Oscilloscope is an essential Time and Labour Saving Instrument. This Photograph—taken by daylight—shows a Double Hemstitch Sewing Machine operating at 1500 R.P.M. Note how all the moving parts appear blurred and indistinguishable. FOR PRICES, THE NEW OSCILLOSCOPE CO., LTD. 11 OSCILLOSCOPE. The First Cost of the Oscilloscope is far below the monetary value of the Time and Labour Saved by its use. This shows the same Sewing Machine, still operating at 1500 R.P.M., but photographed by the light of the Oscilloscope lamp. Note how clearly the moving parts are shown.
