Referee's report by Charles Scott Sherrington, on the Croonian Lecture 'Studies in visual sensation' by Conwy Lloyd Morgan Sectional Committee: Physiology Not recommended for publication in Philosophical Transactions. No modifications seem necessary or desirable and all the accompanying illustrations should be reproduced. It seems unsuitable for Philosophical Transactions since at present it is insufficiently searching and not sufficiently exhaustive either in argument or experimental methods. Its suggestiveness is valuable and its brevity makes it well suited for publication in the Proceedings instead. [Published in Proceedings of the Royal Society, 1901]. Endorsed on verso as received 2 April 1901. 30 March 1901
