Abstract
THE results of a research into the nature of colour vision in the peripheral portions of the retina, carried on by Mr. Baird during the years 1903 and 1904 in the psychological laboratory of Cornell University, have lately been published in a pamphlet. The work so carefully done by Hess and the numerous papers by him on this subject have received fairly general acceptance, and in the present work Mr. Baird confirms most of Hess's conclusions. The reason he gives for the publication of a pamphlet which contains little new work of any great value is that Heilpach, in his research on the nature of colour sensation in the peripheral retina, had arrived at conclusions which controverted many of the statements of earlier observers, and it was deemed advisable to repeat Hellpach's work in order to see whether there might not be some fallacy in the method. Mr. Baird's work practically in every respect confirms that of Hess, and we think there is little doubt that his explanation of the confusing results obtained by Hellpach is correct, that Helipach did not allow sufficient time to elapse between successive stimulations, and consequently the colour sensation due to the immediate stimulation was partly modified by a latent after image of the preceding stimulus.
