Second letter from William Thomson, Lord Kelvin, to George Gabriel Stokes, 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
