✦ Synopsis

Results of experiments concerning attractive forces between flat metal plates, and a description of the apparatus used, are given. The observed attractions do not contradict Casimir's theoretical prediction.

An explanation of results of earlier measurements made by the author on the attraction between clean, and also between silvered glass and quartz plates, all brought in an ionized atmosphere, is suggested. These results were due to differences in the surface potentials of the opposing plates.

1. Introduction.

Casimir 1) derived the following expression for the attractive force F, which exists between two metal plates a distance d apart : F = 0.013/d ~ dynes/cm 9'
