Referee's report by Thomas Romney Robinson, on a paper 'A comparison of the most notable disturbances of the magnetic declination in 1858 and 1859 at Kew and at Nertschinsk; preceded by a brief retrospective view of the progress of the investigation into the laws and causes of the magnetic disturbances' by Edward Sabine Recommended for publication in the 'Philosophical Transactions of the Royal Society'. The paper is important, not so much from the particular researches, but because it opens up further explorations into terrestrial magnetism. Refers to work by Christopher Hansteen. Subject: Physics and Chemistry [Published in the Philosophical Transactions of the Royal Society, 1864] 19 May 1864
