Paper, 'On the amount of light reflected by metallic surfaces' by John Conroy

Description

Conroy writes: 'In a paper which Professor Stokes did me the honour of communicating to the Royal Society [see PP/3/4] [...] I gave an account of some experiments I had made on the amount of light reflected by polished metallic surfaces when ordinary unpolarised light was incident upon them. The light of a paraffine lamp fell either directly, or after reflection from the metallic surface, on a photometer, and the readings were made by altering the distance at which another similar lamp had to be placed from the photometer in order to produce an equal illumination.'
