‎First German edition of this classic paper in chemistry in which he states the law, that when two gases combine chemically, they do so that the volumes are in the ratio of whole small numbers.""In 1805, with Alexander von Humboldt he observed the already known fact that hydrogen and oxygen combines in the ratio of 2 to 1 by volume. Stimulated by this work he studied the reactions of other gases to see whether there were other simple relationshipas, and in 1808 he announced the la of combining volumes, which is now known as GAY-LUSSAC'S LAW, This generalization, obviously connected with some fundamental property of matter, was in part responsible for Avogadro's hypothesis.""(Leicester & Klickstein).Parkinson ""Breakthroughs"", 1809 C. - Leicester & Klickstein ""A Source Book in Chemistry"" pp. 292 ff.‎
