The theory of molecular constitution put foreward....by Couper and Kekulé rested on two main postulates, the quadriivalency of carbon,....and the capacity of the carbon atom for mutual linking or combining together to form a carbon ""chain"". By this hypothesis of the mutual linking together of carbon atoms - which waslater confirmed by experiment - it was possible to explain the formation of organic compounds containing a large number of carbon atoms. On the foundation of their postulates two postulates, moreover, (they) showed how the molecular constitution or mutual linking together of the atoms of a compound could be represented diagrammatically and the relstions between different compounds made readily intelligible. In his classic paper ""On a New Chemical Theory"" (the paper offered here in its first appearance) advanced beyond Kekulé by representing the constitutions of the compounds by means of GRAPHIC FORMULA in which, as at the present day, the valencies pf the atoms are represented by lines....his formulae are similar to those at present in use...""(Findlay pp. 34 ff)""The theory of Kekulé and Couper gave the chemists the maeans of solving the problems of chemical constitution"" and by means of the graphic or constitutional formulae it became possible to represent the molecular constitution of known compounds and to foresee the possible existence of isomeric compounds.""(Findlay).Parkinson ""Breakthroughs"" 1858 C.The volume contains another importent, monumental memoir MARCELLIN BERTHELOT ""Sur la Synthèse des Carbures D'Hydrogene"", pp. 69-208.

At the time there were still six gases that were considered permanen: oxygen, nitrogen, hydrogen, nitrogen dioxyde, acrbon monooxide, and acetylene. Liquefaction had not been achieved despite the use of what were considered ernomous pressures. At the end of 1877 and the beginning of 1878 Callitet liquefied all these gases shortly before Raoul Pictet, who employed a completely different procedure. Cailletet had, following Andrews, recognized the importence of the critical temperature, above which liquefaction of a gas does not take place. In order to produce the necessary ccoling, he had recourse to expansion, sometimes employing several expansions in a staged process. It was in this manner that he succeeded in liquefying oxygen by beginning with liquid ethylene and passing through the stage of liquid methane.""(DSB III, pp. 11-12).

He sought to devise comprehensive classificatory schemes for organic compounds and for the elements. Dumas’s earliest contribution to organic chemistry was his study of nine alkaloids, published in 1823, jointly with Pierre Pelletier.1 He analyzed the elemental constituents of these organic “bases” and attempted to prove that their relative proportions of oxygen followed Dalton’s law of multiple proportions. He had embraced the ideas of the two reigning theories in contemporary chemistry: dualism, with its division of substances into electronegative (acid) and electropositive (alkaline)"" and atomism, which Dalton had used to explain his law. Dumas spent the next few years attempting to create an adequate system of classification of organic compounds based upon these two theories.""(DSB).‎

‎First appearance in France of Hess' two fundamental laws in thermodynamic 1: ""the law of heat formation"" (1840), anticipating a specific example of the ""LAW OF THE CONSERVATION OF ENERGY"", 2 years before Julius Robert Mayer elucidated the more general principle in 1842 - claiming that ""the heat developed in chemical change is constant, whether the change occurs directly or indirectly in several stages""and 2: ""the law of thermoneutrality"" (1842), stating, that when neutral salts exchange acids and bases in solution, the heat of the reaction is zero. - These papers were published at the same time in France and in Russia. Germain Henri Hess is noted today for two fundamental principles of thermochemistry: the law of constant summation of heat (known simply as Hess's law) and the law of thermoneutrality. These discoveries were remarkable in that they were postulated without any supporting theoretical framework and took place in a field of study almost totally neglected by his contemporaries. Hess's law is of immense practical importance and is used to this day to determine heats of reaction when their direct measurements are difficult or impossible. (Chemistry Encyclopedia).""Numerous men, notably Lavoisier and Laplace had measured the heats evolved in various reactions, but thermochemistry received its first importent advance at the hands ofgermain Henri Hess, who showed that the heat evolved in a reaction is the same regardless of whether the reaction is carried out directly or in a number of steps. This generalization, known now as ""Hess's Law"", makes possible the calculation of heats for many reactions where direct measurement are impracticable.""(Leicester & Klickstein, A Source Book..., p329.""The thermochemical work of Hess was continued extensively in the second half of the nineteenth century through the studies of Thomsen and Berthelot. Both Berthelot’s principle of maximum work and the thermodynamic theories of affinity which came to prevail were clearly foreshadowed in the work of Hess. In addition to his internationally known research in thermochemistry, Hess was very influential in the development of chemistry in Russia. His text Osnovania chistoy khimii (Fundamentals of Pure Chemistry) went through seven editions and did much to establish the chemical nomenclature of the Russian language. He was always interested in technological questions, and many of his students later contributed to Russia’s industrial development.""

The light portions of the image darkened the salts, while the shadowy portions left them unaffected. The unchanged salt was dissolved away by sodium thiosulfate (a process that had been suggested by John Herschel and a permanent image of sorts was left behind.""(Asimov).Together with JEAN CHARLES PELTIER ""Mémoire sur la Formation des Tables des Rapports qu'il y entre la Force d'un Courant électrique et la Déviation des aiguilles des multiplicateurs"" suivi de Recherches sur la Causes de Pertubation des couples thermo-électriques..."", pp. 225-313.‎

‎First appearance of Lavoisier's FIRST PUBLISHED CHEMICAL PAPER introducing quantitative methods in chemistry, and in which he for the first time brought a hydrometer in use to measure the specific gravities of components of a chemical solutions. Lavoisier defended the originality of his approach in the following words: ""It is to the art of combination that the knowledge of the specific gravities of fluids can bring most light. This aspect of chemistry is much less advanced than we thought, we possess barely the rudiments of it."" ""This first paper, which in so many respects embodies the quantitative methods Lavoisier was to employ in his later work, had in fact been largely anticipated by others, notably by Marggraf, who had already discovered the composition of gypsum and shown that it contained water (phlegm). Yet Lavoisier’s work was more through" and his paper, his first contribution to the Academy of Sciences (read to the Academy on 25 February 1765), appeared in 1768. (The paper offered). - Lavoisier’s earliest chemical investigation, his study of gypsum, was mineralogical in character" begun in the autumn of 1764, it was intended as the first paper in a series devoted to the analysis of mineral substances. This systematic inventory was to be carried out, not by the method of J. H. Pott ""who exposed minerals to the action of fire"" but by reactions in solution, by the ""wet way."" ""I have tried to copy nature,"" Lavoisier wrote. ""Water, this almost universal solvent ""is the cheif agent she employs"" it is also the one I have adopted in my work."" Using a hydrometer, he determined with the care the solubility of different samples of gypsum (samples of selenite, or lapis specularis, some supplied by Guettard and Rouelle). He made similar measurements with calcined gypsum(plaster of paris). Analysis convinced him that this gypsum was a neutral salt, a compound of vitriolic (sulfuric) acid and a calcareous or chalky base. Not content with having shown by analysis the composition of the gypsum, Lavoisier completed his proof by a synthesis following, as he said, the way that nature had formed the gypsum. He further demonstrated that gypsum, when transformed by strong heating into plaster of Paris, gives off a vapor, which he showed to be pure water, making up about a quarter of the weight of gypsum. Conversely, when plaster of Paris is mixed with water and turns into a solid mass, it avidly combines with water. Using the expression first coined by Rouelle, he called this the ""water of crystallization."" (DSB).Partington III, pp. 378-79. -‎

‎""Frémy’s first project was to continue Pelouze’s studies of iron oxides, and he expanded them to include oxides of chromium, tin, and antimony that form salts with alkalies in the same way as manganese. In 1835 he published a memoir in the Annales de chimie on the splitting of fats by sulfuric acid, a process that was adopted by French industry. From then on, Frémy pursued scientific investigations as professor and industrial work as consultant (later as administrator of the Compagnie de Saint-Gobin). He proposed improvements in the chamber process for making sulfuric acid (low temperature and ample air and water), and he introduced the residue from burning pyrites as the raw material for iron production. From research on the setting of hydraulic cement, Frémy proceeded to the synthesis of rubies by heating alumina with potassium chromate and barium fluoride.""(DSB).‎
