Second referee's report by Charles Scott Sherrington, on a paper 'The colour-physiology of higher crustaceae' by Frederick Keeble and Frederick William Gamble Sectional Committee: Zoology Recommended for publication in Philosophical Transactions, in full. All the illustrations seem of value to the clear exposition of the theme. The character of the subject lends itself to, and requires especially description by drawings. The target diagrams need not be reproduced either with colour or at more than half linear scale. [Published in Philosophical Transactions B, 1902]. Endorsed on verso as received 19 June 1903.
