Referee's report by D'arcy Wentworth Thompson, on a paper 'The role of the body fluid in relation to movement in soft-bodied invertebrates I. The burrowing of Arenicola' by G Chapman and G E Newell Sectional committee: Zoology The paper is 'of poor quality, thin and meagre and not good enough for the R[oyal] S[ociety]'. The diagram seems arbitrary. Some elementary facts about burrowing worms are not taken into consideration. [Published in Proceedings of the Royal Society B, 1947].
