I endeavoured to find some liquids which would insulate well, and could be obtained in sufficient quantity for these experiments.

The electroscope will now insulate well enough to show no appreciable collapse of the leaves in one or two hours' time.

The kerosene is then removed and its place taken by vaseline or paraffin, known to insulate well as a standard for comparison.

In the limo's doors are insulated wells stocked with pop and beer and crescent-shaped ice cubes, and we've made a mess of these as well.
