Referee's report by Edwin Ray Lankester, on a paper 'On some histological features and physiological properties of the post-œsophageal nerve cord of the crustacea' by William Bate Hardy Recommended for publication in Philosophical Transactions. The work 'constitutes a real contribution to an interesting and important subject'. Despite this, it is not of any 'special excellence or novelty', but there is no standard supplied for the admission of papers to the Philosophical Transactions so he cannot offer a more definite opinion. Subject: Biology [Published in Philosophical Transactions A, 1894]. 14 June 1891
