Title	Paper, 'Some experiments on metallic reflection. V. On the amount of light reflected by metallic surfaces. III' by John Conroy
Date	1884
Description	Conroy writes: 'Professor Stokes recently communicated to the Royal Society (“Proc. Roy. Soc.,” vol. 36, p. 187) [see PP/4/17] an account of some determinations I had made of the amount of light reflected by steel and speculum metal mirrors when polarised light was incident upon them. I have repeated these experiments with films of silver chemically deposited on glass, as such films approximate more closely to theoretically perfect metallic surfaces than any metallic mirror, however carefully polished, and also because very different statements have been made as to the reflective power of such films; one observer having said that silvered glass mirrors reflect about 90 per cent, of the light incident upon them, whilst another made their reflective power only equal to that of speculum metal.' Annotations in pencil and ink throughout. Subject: Optics Received 6 May 1884. Read 15 May 1884. Communicated by George Gabriel Stokes. A version of this paper was published in volume 37 of the Proceedings of the Royal Society as 'Some experiments on metallic reflection. No. V. On the amount of light reflected by metallic surfaces. III'.
