A NOVEL EXHIBITION AT OLYMPIA.
Alexander Duckham & Co.’s exhibit of non-gumming, non-freezing ADCOL ‘ lubricants includes a petrol engine turning at high speed and illustrating one way in which unsuitable oil reduces efficiency.

Thus the delayed closing of a badly lubricated valve can be watched, although actually it occupies only a few thousandths of a second.
