Referee's report by Gilbert Thomas Morgan, on a paper 'The ureides of p-aminophenylstibinic acid' by W H Gray, John William Trevan, H W Bainbridge and A P Attwood Sectional committee: Physiology Recommended for publication in Proceedings, with some abbreviation. The experimental part is too long and should be shortened and some of the graphic formulae should be omitted. The paper is important but 'obcurely written' with too much detail on laboratory procedures. [Published in Proceedings of the Royal Society B, 1931]. Endorsed on verso as received 13 January 1931
