First appearance of a classic paper in which Proust describes his discovery of Grape.Sugar and the identificationof this with glucose. He investigated the varieties of sugar that occur in sweet vegetable juices, distinguishing three kinds, and he showed that the sugar in grapes, of which he announced the existence to his classes at Madrid, is identical with that obtained from honey by the Russian chemist J. T. Lowitz.Proust is famous for his work on the steadiness of composition of chemical compounds.""In chemistry, the law of definite proportions, sometimes called Proust's Law, states that a chemical compound always contains exactly the same proportion of elements by mass. An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition. For example, oxygen makes up 8/9 of the mass of any sample of pure water, while hydrogen makes up the remaining 1/9 of the mass. Along with the law of multiple proportions, the law of definite proportions forms the basis of stoichiometry.""(Wikipedia).
