Paper, 'On the variation of the electrical resistance of glass with temperature, density, and chemical composition' by Thomas Gray

Description

Gray writes: 'The following paper is a description of the methods adopted, and of the results obtained, in a series of experiments on the specific resistance of glass. These experiments were performed in the Physical Laboratory of the Imperial College of Engineering, Tokio, Japan. An account of some preliminary experiments on this subject was communicated by the author of this paper to the “Philosophical Magazine” for October, 1880. In that paper attention was specially directed to the change of resistance with change of temperature, and to an apparently permanent change in electric quality which the glass underwent when subjected to a high temperature. Subsequent experiments have served to confirm the results there given, but show that if the glass be newly made very little, if any, permanent change is brought about by heating.'

Annotations in pencil and ink. Includes a diagram of experimental apparatus and a graph of experimental results.
