Letter from George Gabriel Stokes, to James Clerk Maxwell, regarding a paper 'On certain dimensional properties of matter in the gaseous state. - Part I. Experimental researches on thermal transpiration of gases through porous plates and on the laws of transpiration and impulsion, including an experimental proof that gas is not a continuous plenum. - Part II. On an extension of the dynamical theory of gas, which includes the stresses, tangential and normal, caused by a varying condition of gas, and affords an explanation of the phenomena of transpiration and impulsion' by Osborne Reynolds The Committee has agreed to publication of the first part, with no decision yet on the mathematical second part, which will require alterations. William Thomson, Lord Kelvin [RR/8/189] is willing for his report to be seen by James Clerk Maxwell, who is willing to let his be seen in turn [RR/8/188]. Suggests they communicate and agree to a set of recommendations for the author. William Thomson, 1st Baron Kelvin notes on 6 June 1879 - The author will see no offense is meat by his remarks in the report. Suggests he refer more explicity to Schmidt [?], Rudolf Clausius, James Clerk Maxwell, Peter Guthrie Tait, James Dewar and George Johnstone Stoney. Subject: Physics and Chemistry [Published in the Philosophical Transactions of the Royal Society, 1879] 3 June 1879
