Referee's report by James Alexander Murray, on a paper 'On experiments on the chorio-allantoic membrane of the chick egg with regard to the action of homogeneous x-ray irradiation' by E S Duthie Sectional Committee: Physiology Not recommended for publication in the 'Proceedings of the Royal Society of London'. Refers to work of C M Scott, to which the current paper adds nothing. Wonders why the authors continue with the current experimental method, and why there is no reference made to the work of C M Scott.
