Letter from Edwin Edser, Goldsmith's College, University of London, New Cross, to [William Fletcher] Barrett Explains the shadow experiment from Mr Winn's paper, which Barrett has read. Lord Rayleigh has come up with the same idea, but confessed that the notion of the eye forming a negative picture has not occurred to him before. Edser believes that this should be published. Winn's paper has been submitted to the Physical Society, but was refused for being too long. 13 February 1907
