Referee's report by Edwin Ray Lankester, on a paper 'Further observations on the locomotor system of medusae' by George John Romanes Recommended for publication in the 'Philosophical Transactions of the Royal Society'. The author is willing to reduce the paper if the Committee provide reference to areas which can be omitted. Suggests the omission of the experimental parts not directly related to the paper, and which might form the basis for further researches, but does not feel confident in identifying such passages.
