Referee's report by George Biddell Airy, on a paper 'Further experiments on light' by Henry Lord Brougham Not recommended for publication in the 'Philosophical Transactions of the Royal Society'. This second paper is considered better than the first, in that it contains less crude theory. It is worse than the first, in that it contains less 'novel experiment'. 'But is is comparable to the first in this respect, - that it is written in entire ignorance' of the principles and results of the great undulatory theory. 'The paper is more than twenty years behind the actual state of science'. Suggests that any writers putting papers to the Royal Society should have made themselves well acquainted with current theories 'before he troubled the Society with such useless speculations'. Subject: Physics and Chemistry [Published in the 'Proceedings of the Royal Society of London] 17 June 1852
