I have sometimes wonder'd that the Londoners did not, from the effect holes in the bottom of the globe lamps us'd at Vauxhall have in keeping them clean, learn to have such holes in their street lamps. But, these holes being made for another purpose, viz., to communicate flame more suddenly to the wick by a little flax hanging down thro' them, the other use, of letting in air, seems not to have been thought of; and therefore, after the lamps have been lit a few hours, the streets of London are very poorly illuminated.
