He carried on numerous photographic and photochemical experiments and he was one of the founders of the London Photographic Society. These experiments with organic and inorganic light-sensitive substances, which, with characteristic unselfiness, he made publicg during the early forties of the lat century, were extremely useful in the study of photochemistry, which was the in its infancy, and were of great servicee for years to those who came after him and used his researches for the basis of their studies.""(Eder: ""History of Photography"", p. 326.‎

‎First appearance of an extremely importent paper in the histroy of chemistry as Frankland here introduced the concept of 'VALENCY' - he called it 'atomicity' - to explain the capacity of atoms to combine with other atoms. ""This led not only to the Kekulé structures, but also to the periodic table of Mendeléev, since that table was based on the regular change of valence with atomic weight.""(Asimov).""On May 10 1852 Frankland read to the Royal Society a paper on organic metallic compounds (the paper offered) in which he made the emperical observation that elements possessed fixed combining powers, or ""only room, so to speak, for the attachement of a fixed and definite number of the atoms of other elements."" The expression ""valence"" or ""Valency"" began to be used by other chemists only after 1865, wheras Frankland tended to use the misleading term ""atomicity""....Frankland's teching position at the Royal College of Chemistry and his influence on the Department of Sciences and Art science examinations enembled him to spread the idea through the younger generation of British chemists.""(DSB V, p. 126).The exact inception, however, of the theory of chemical valencies can be traced to an 1852 paper by Edward Frankland, in which he combined the older theories of free radicals and ""type theory"" with thoughts on chemical affinity to show that certain elements have the tendency to combine with other elements to form compounds containing 3, i.e. in the three atom groups (e.g. NO3, NH3, NI3, etc.) or 5, i.e. in the five atom groups (e.g. NO5, NH4O, PO5, etc.), equivalents of the attached elements. It is in this manner, according to Frankland, that their affinities are best satisfied. (Wikepedia).‎

‎First full exposition of Pasteur's first revolutionary paper on the discovery of ""molecular assymetry"" - also constituting his first published scientific paper. In order to secure priority, Pasteur announced his discoveries first in its preliminary form in a short paper of 4 pages in ""Recherches sur le dimorphisme"", Comptes rendus hebdomadaires des séances de l' Académie des Sciences, 20 mars 1848, XXVI, pp. 353-355. In the offered form it is the first full treatment of his discoveries.""Pasteur came to the conclusion, on one hand, that all tartrates could be regarded as mutually isomorphic, but at the same time - based on Mitscherlich's work - that the sodium ammonium salts of both the tartaric and racemic acids also crystallized isomorphically, which in turn suggested that all racemic and tartaric salts would crystallice identically. An they do crystallice identically, albeit in a very special way Half the crystals of the racemic salts are characterized by a mirror-inverted form.""(Hans-Werner Schütt in ""Eilhard Mitscherlich"").""Another discovery of great importence was made by Pasteur. In 1844 Mitscherlich had stated that the crystals of sodium ammonium tartrate and sodium ammonium racemate were identical, although solutions of the former were found to be active but those of the latter were inactive. Since this statement was contrary to his views on the relation between crystalline form and optical activity, Pasteur examined these salts and found, it is true, that the crystals of the tartrate resembled the other tartrates which he had examined i possessing hemihedral faces arranges in a similar manner. The crystals which was obtained from a solution of the inactive racemate, at the ordinary temperature, were also found, contrary to expectation, to have hmihedral faces....""(Alexander Findley in ""A Hundred years of Chemistry"", p.59-60).It is related that Pasteur, on making this discovery, rushed from his laboratory and, meeting the lecture assistant in physicss, embraced him, exclaming: ""I have just made a great discovery! I have separated the sodium ammonium paratartrate into two salts of opposite action on the plane polarisation of light. The dextro-salt is in all rspects identical with the dextro-tartrate. I am so happy and overcome by suchnervous excitement that I am unable to place my eye again to the polariization apparatus."".Among other importent chemical papers the volume contains Gay-Lussac: Mémoire sur L'Eau Régale.

‎First printing of an importent paper in which Gerhardt introduced the concept of ""type"" in organic chemistry in order to understand all substitution reactions.""Gerhardt adopted Laurent's nucleus, or unitary theory and combined it with the theory of types and radicals. In 1852 he discovered the anhydrides of organic acids and explained their structure by an extension of the water type of Williamson. He further proposed that all organic compounds could be related to one of four inorganic types: water, hydrogen, hydrogen chloride, and ammonia. These types could be used to explain most organic reactions as double decompositions. Since Gerhard felt that the formula of organic compounds never ecpressed the actual structure of the molecule, but only its reactions, he was satisfied with this theory and carried it no farther. However, it was a great advance in systematization and helped to bring order into the confused field of organic reactions.""(Leicester & Klickstein ""A Source Book in Chemistry 1400-1900"", p. 351.).""Gerhardt will occupy a permanent position in the history of Chemistry for his services to organic classification, for his concept of homology, for his preparation of acid anhydrides, and for his reform of equivalents.""(DSB V, p. 374).The volume contains further importent papers Marcelin Berthelot ""Sur la Bichlorhydrate D'Essence de Térébenthine"", pp. 223-230, by Arago, Edmond Becquerel etc.etc.‎

‎First printing of this milestone paper, containing the first scientific classification of foodstuffs as carbonhydrates, fats, proteins, and water.""The brilliant demonstration in 1824 that the gastric juices of animals contains hydrochloric acid appeared incredible to many of Prout's contemporaries. Yet in 1827 (in the paper offered) they readily adopted his classification of foodstuffs into water, saccharinous (carbonhydrates), oleagineous (fats), and albuminous (proteins). Although Prout promised detailled analyses of the three organic aliments, only those of the saccharinous class were published by him. As a vitalist, Prout maintained that organized bodies (which were composed from organic substances) contained ""independent existing vital principles.""Under the influence of these teleological agents, the four aliments were transformed into blood and tissues. Prout termed the process of digestion and blood formation ""primary assimilation."" ""Secondary assimilation"" (Liebig's ""metamorphosis of tissues"") included both the process of tissue formmation from blood and the destruction and removal of unwanted parts from the animal system. The absorption and removal of water from processed aliments were the principal chemical features of chylification and sanguification, respectively. Organization of processed aliments could not occur, however, without the presence and admixture of minute amounts of water or of elements other than carbon, hydrogen, oxygen, and nitrogen. In 1827 Prout coined the word (in the paper offered) ""merorganized"" to denote the isomerism and vitalization of organic substances by the presence of these incidental materials.""(DSB XI, p. 173). - Parkinson ""Breakthroughs"" 1827 C.‎

Bunsen and Roscoe found that for some time after the experiment started - a time they called the induction period - no reation took place"" then the reaktion rate slowly increased until a constant rate, proportional to the intensity of the light source used, was reached. The effect of the incident light was related to the wavelenght and followed a law of inverse squares.....(they) determined that the energy of light radiated by the sun in one minute is equivalent to the energy needed for the conversion of 25x10 with a potens of 12 cubic miles of a hydrogen-chlorine mixture into hydrogen chloride.""(DSB II, pp. 589).The papers contains the description of the ACTIONOMETER, which measures the heating power of electromagnetic radiation.

This invention furnished Bunsen & Kirchhoff with a non-luminous gas-flame of failrly high temperature, in which chemical substances could be vaporized and a spectrum could be obtained, due purely and simply to the luminous vapour.Leicester & Klickstein ""A Source Book in Chemistry"", pp. 355-360).‎

‎First appearance of an importent paper in which Van't Hoff ""showed from quantitative experiments on osmosis that dilute solutions of cane sugar obey the laws of Boyle, Gay-Lussac, and particularly leading to an extension of Avogadros law. He here announced the laws which bears his name and which apply to ideal solutions ""solutions which are diluted to such an extent that they are comparable to ideal gases."" Einstein in 1905 and later made importent applications of these laws.""Thus van't Hoff was able to prove that the laws of thermodynamics are valid not only for gases but also for dilute solutuions. His pressure law gave general validity to the electrolytic theory of Arrhenius,,,consequently van't Hoff became an adherent of the theory of electrolytic dissociation.""(DSB XIII, p. 579. In 1901 Van't Hoff was the first to receive the Nobel Prize for chemistry.‎
