Letter from S E Sheppard, Ravensmere, Bromley Road, Catford, to the Secretaries of the Royal Society, Burlington House Dr Wilderman has drawn Sheppard's attention to an ommission in his paper ['The theory of the photographic process: on the chemical dynamics of development' by S E Sheppard and C E K Mees], of any mention of Wilderman's work. Sheppard therefore requests a correction to be made if still possible. 6 February 1905
