Referee's report by Thomas George Bonney, on a paper 'The rubies of Burma and associated minerals: their mode of occurrence, origin, and metamorphoses. A contribution to the history of corundum' by C Barrington Brown and John Wesley Judd Recommended for publication in the 'Philosophical Transactions of the Royal Society'. Suggests omitting the section on economics, which is of a more practical, rather than scientific, nature. Suggests shortening the sections by C Barrington Vrown, which are a little diffuse. Has no hesitation in recommending publication of the parts by John Wesley Judd. Suggests which illustrations should be reproduced. Subject: Geology, Crystallography [Published in the Philosophical Transactions of the Royal Society, 1896] nd [1895]
