Printed proof, 'On the examination for colour of cases of tobacco scotoma, and of abnormal colour blindness' by William De Wiveleslie Abney

Description

Abney writes: 'The following cases were submitted to the Colour Vision Committee, and it was thought desirable that the results of the examination should be communicated to the Royal Society. The examination of these three cases was conducted at different times, the first partially in the presence of the Colour Vision Committee by Mr. Nettle ship, and the two last, and part of the examination of the first, at different times, in my laboratory, with the assistance of Mr Nettleship. In all three cases the examination made was an ability to distinguish colour, luminosity of the different parts of the spectrum, and total sensation of light; and, in addition, in the first case, to range of colour sensation on the retina.' Abney presents the case studies of Alfred C, Alfred P and William P.
