Referee's report by John Burdon Sanderson Haldane, on a paper 'Control of nucleic acid supply in the hamster' by P C Koller Sectional committee: Zoology Not recommended for publication in its present form. The results are interesting but the reasoning seems to be fallacious. The author isn't justified in putting forward a biochemical explanation without biochemical evidence. If published, the title should be changed. [Published in Proceedings of the Royal Society B, 1946 with the title changed to 'Control of nucleic acid charge on the X-chromosome of the hamster']. Date received not given. 1945
