IV. An account of an experiment, confirming one lately made, touching the production of light, by the effluvia of one glass falling on another in motion.
Abstract
Having observ'd that the effluvia of glass were capable of exhibiting a phenomenon falling on an exhausted glass in motion, as if rub'd by a visible solid body, (as I lately show'd before this Honourable Society;) I thought a farther confirmation of the same, would not be unacceptable.
