Referee's report by John Desmond Bernal, on a paper 'Evidence on spiral structure and chromosome pairing in osmunda regalis L' by Irene Manton Sectional committee: Botany Recommended for publication in Philosophical Transactions. The presentation of the plates is 'extremely confusing' and should be modified. The account seems 'somewhat long and involved'. The paper should be published for the benefit of cytologists.
