Electrostatic Series

A table of substances arranged in the order in which they are electrostatically charged by contact, generally by rubbing against each other. The following series is due to Faraday. The first members become positively excited when rubbed with any of the following members, and vice vers a. The first elements correspond to the carbon plate in a galvanic battery, the succeeding elements to the zinc plate. Cat, and Bear-skin--Flannel--Ivory--Feathers--Rock Crystal--Flint Gla --Cotton--Linen--Canvas--White Silk--the Hand--Wood--Shellac--the Metals (Iron-Copper-Bra -Tin-Silver-Platinum)--Sulphur. There are some irregularities. A feather lightly drawn over canvas is negatively electrified; if drawn through folds pre ed against it it is positively excited. Many other exceptions exist, so that the table is of little value. 236   STANDARD ELECTRICAL DICTIONARY.
