Referee's report by Robert Edmond Grant, on a paper 'On the anatomy and physiology of the Spongiadae.—Part II' by James Scott Bowerbank Recommended for publication in the 'Philosophical Transactions of the Royal Society'. Regrets that there was only a month available to read the paper, as they would have liked longer to enjoy it. Refers to previous paper by the same author. The author is known throughout Europe as a skilled perparator and microscopist, and has the largest collection of Porifera in Europe. Refers to work of Luigi Ferdinando Marsili, Filippo Cavolini, Johann Schweigger, Ellis [?], Johnstone [?], Carter [Henry John Carter?], Thomas Henry Huxley and Johann Nathanael Lieberkühn. Considers the paper one of the best they have ever read, and that 'no medal or honor [sic] in the gift of the Royal Society conferred on the author, could adequately express the gratitude of at least one fellow-member'. Subject: Zoology [Published in the Philosophical Transactions of the Royal Society, 1862] 22 July 1861
