Copy letter from James Hopwood Jeans, Secretary of the Royal Society; to Professor [Sydney] Chapman, FRS Refers to the paper by J. E. Jones, 'On the velocity distribution function and on the stresses in a non-uniform rarefied monatomic gas', that Professor [Sydney] Chapman communicated to the Society. Notes that he has read it with much interest, however, fears that he will struggle to find two referees willing to look through the paper as careful as is necessary. Asks Professor Chapman to what extent he has worked through the analysis and arithmetic, and if he can vouch for its accuracy. 27 October 1921
