In 1819 Dulong and Petit announced that there was a simple relationship between specific heats and atomic weights. Although they suggested that their law might be extended to compounds, it was F. E. Neumann who, in 1831, first applied the law practically to solid compounds. Avogadro, who began his research in this field in 1833 (in the paper offered), ivestigated both liquids and solids.He decided that the formula of a compound in the liquid or solid state could not be the same as that in the gaseous state. He therefore introduced the arbitrary division of molecules and considered, for example, that a molecule of water or ice contained only a quarter as many atoms as one of steam.(DSB).Also with Eilhard Mitscherlich ""Sur le Rapport de la Densité des gaz à leur poids atomiques"", pp. 5-41, textillustr. and his ""Sur la Benzine et les Acides des Huiles et de Stároptes"", pp. 41-59.
