‎First German edition of both papers, constituting the first 2 papers in his ""Experimental Essays on the constitution of mixed gases...."" (1802) in which he formulated his famous gas laws and raised the foundation of the atomic theory in chemistry.The publication of these papers gave him at once international reputation they tried to explain why the gases of the atmosphere remain mixed instead of segregating with the heaviest element at the bottom, it states that the maximum density of a vapour in contact with its liquid remains the same whether other gases be present or not and the vies that the particles of everykind of elastic fluid are elastic only with regard to their own kind, and that the total pressure of the atmosphere equals the sum of the pressures exerted by the individual gases, each of which excerts its pressure independently of the others. This was the first step toward his atomic theory of in chemistry. ‎
