‎First German translations of these fundamental papers in which Dalton formulated his gas-and pressure laws, such as ""The Law of Partial Pressures"" , ""The Charles Law"" or The Charles-Gay-Lussac Law"" (this law arrived at almost simustaneously with Gay-Lussac).These papers were read and published in the memoires from the ""Manchester Literary and Philosophical Society"" in 1801 and 1802 in 4 parts, the German translation, the item offered, is divided in 5 parts, probably incorporating the paper from Nicholson's Journal from 1801. 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 otal 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. - He also showed that the quantity of water evaporated in a given time to be stricktly proportional to the force of aqueous vapour at the same temperature, and last, announcing the law that all elastic fluids expands the same quantity by heat, ""The Charle's Law or Charles-Gay-Lussac Law"".‎
