‎First printing of an importent paper in which Dalton clarifies certain unclear points in his famous essays ""Experimental essays on the constitution of mixed gases...."", published 1801-02. These essays ""gave him at once European reputation... by these discoveries meteorology was constituted a science"" (D.N.B.).""I propose therefore (after some misunderstanding from Thomson and others), 1st, To state, in as clear a point of view as the subject will admit, the principles which I assume: 2d, To show that the consequences which I have deduced from them are legitimate"" and, particularly, that mixed elastic fluids ought not to arrange themselves according to their specific gravity: and, 3d, To demonsrate that the supposition of the gases constituting the stmospere being held in a state of equal diffusion by chemical affinity, is not only inconsistent with the phaenomena, but is completely absurd"" (John Dalton in the paper).Smyth ""John Dalton... A Bibliography"", No 29 (listing it here as it was the same text as part 4, which it is not). ‎
