Letter from George Howard Darwin, on a paper 'On the vibrations and stability of a gravitating planet' by James Hopwood Jeans to Joseph Larmor Sectional Committee: Mathematics He presents a paper by Jeans. If the Committee care to take his opinion as that of referee, he recommends that it be accepted and that the figures should be printed. The subject matter is 'no doubt' highly speculative but the speculation is interesting and suggestive and supported by argument. [Published in Philosophical Transactions A, 1903].
