Detailed referee's report by Robert Warington, on a paper 'Further observations on the nature and functions of the nodules of leguminous plants' by Maria Dawson Recommended for publication in the 'Philosophical Transactions of the Royal Society', in part. Suggests omitting part three. Suggests adding a statement on the production of the bacterioids. The third section of the paper is interesting, but the evidence is imperfect and the conclusions uncertain. Recommends publishing the short section on adaptability, along with a statement of the number of experiments made.
