‎First appearance of this classic paper in organic chemistry in which Wöhler and Liebig showed how Amygdalin could be decomposed by a vegetable emulsion, the first example of a glycoside.""The conclusions which you have drawn from the investigation of bitter-almond oil,"" wrote Berzelius to Liebig and Wöhler, ""are certainly the most importent which have so far been reached in the domain of vegetable chemistry, and give promise of shedding an unexpected light over this part of the science...The facts which you have set forth inspire such reflections that they may be regarded as the dawn of a new day in vegetable chemistry.""(Berzelius-Wöhler Briefwechsel).""During the years that Liebig was preoccupied with the ether theory and with organic acids, he also carried out two importent investigations with Wöhler. In october 1836 Wöhler wrote that he had discovered a way to transform amygdalin to oil of bitter almonds and hydrocyanid acis, by distilling it with manganese and sulfuric acid, and he invited Liebig to join in pursuing the topic. Two days later he made a more remarkable discovery. It had occurred to him that perhaps thetransformation of amygdalin could be effected by the albumin in the almonds, in a manner similar to the action of yeast in sugar...Wöhler suspected that the decomposition was an example of what Berzelius had recently defined as catalysis. Liebig and Wöhler then divided up the detailed examination of the properties and composition of amygdalin. They precipitated from the emulsion of almonds a substance which when dissolved retain its action. They named the active substance ""emulsion"". Its effectiveness in very small quantities confirmed that it acted like yeast.""(DSB VIII, p. 342).‎

‎In this paper the two famous French chemists announced the first isolation of, and the naming of the substance Chlorofyll, the green substance essential for photosynthesis.Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesise carbohydrates from CO2 and water. This process is known as photosynthesis and is the basis for sustaining the life processes of all plants. Since animals and humans obtain their food supply by eating plants, photosynthesis can be said to be the source of our life also.‎

‎The Calculus of Chemical Operations"" being a Method for the Investigation, by means of Symbols, of the Laws of the Distribution of Weight in Chemical Change. Received April 25, Read May 3, 1866. Part I-II. (I. On the Construction of Chemical Symbols. ...‎

‎(London, Taylor and Francis, 1866 a. 1877. 4to. No wrappers as extracted from ""Philosophical Transactions"", Vol. 156 - Part II a. vol. 167 - Part I. Pp. 781-859 a. pp. 35-116. Clean and fine.‎

‎First appearance of both papers, controversial as Brodie here tries to established a new chemical philosophy, refusing atomism and founding the calculation of chemical processes on Boolean Algebra, defining chemical symbols with mathematical terms and notations. The work is a remarkable attempt to set chemistry on a rational deductive basis. - The introduction in the second paper meets the main points raised by his critics.""In 1866 the Royal Society began to publish Brodie’s ""The Calculus of Chemical Operations"" (Philosophical Transactions, 156 [1866], 781-859"" 167 [1877], 35-116) which introduced Greek symbols for the chemical elements to replace the roman alphabet (Berzelian) symbols that contemporary chemists used to represent atomic weights. Brodie’s symbols, however, represented operations on space (volumes), not weights for, besides its revolutionary symbolism, the calculus also demanded an appreciation of George Boole’s algebraic logic, which Brodie had studied after the publication of Boole’s Investigation of the Laws of Thought in 1854. In this an equation such as y = xy is a symbolic statement that y is a subset of x in which the symbol x is an operator on y. Although professional mathematicians like William Donkin and Henry Smith later advised Brodie, it appears that he developed the system without professional help. The principal difficulty about the calculus for the present-day historian and philosopher of science is the need to explain it before going on to discuss it and the difficulty of giving any concise description of it. Boole had developed the concept of symbolic operators in algebraic analysis. These provided a code as to how the symbols were to be understood and manipulated. Brodie exploited this in the idea of a chemical operator, or chemical operations, that he symbolized by Greek letters. It is probably unwise, therefore, to interpret Brodie’s philosophy as analogous to Percy Bridgman’s later operationism. He proposed that if two substances with the empirically-derived weights, x and y combined to form a new compound with weight xy, then x + y = xy. From such weight equations he constructed a symbolic algebra that bypassed any atomistic interpretation.""(William H. Brock in ""Hyle Biography"").‎

Supplementband. Pp. 354-364 a. 1 folded plate (The atomic volume curve). The entire volume offered ""VII. Supplementband."" (4),380 pp. and 3 folded plates. Small stamp on titlepage and verso of.‎

‎First appearance of this groundbreaking, classic paper in which Lothar Meyer first fully expressed his ideas of the relationsships between the atomic weight of the elements and their properties. In his ""Curve"" he plots the atomic volumes of the chemical elements against their weights and connects the points to obtain a curve with proonounced peaks and valleys. The periodicity in atomic volume and electrochemical behaviour revealed by this curve is matched by periodicities in other properties, such as fusibility and volatility etc.The ""Periodic Law"" may be stated in the words: The properties of the Elements are a periodic function of (or vary in a periodic manner with) the atomic weight. (Findlay).Lothar Meyer and Dimitri Mendeleev independently discovered the periodic system, but ""Meyer did not publish this work until after the appearance of Mendeleev's first paper on the subject in 1869. His table was very similar to that of Mendeleev, but it contained some improvements and was, perhaps, influential in causing some of the revisions made by Mendeleev in the second version of his table, published in 1870. In general, Meyer was more impressed by the periodicity of the physical properties of the elements, while Medeleev saw more clearly the chemical consequences of the periodic law.""(Source Book in Chemistry, p. 434). - Weeks p. 207 ff.‎

It is unstable and explodes on heating to give chlorine and oxygen. Davy here suggested the name 'chlorine', from a greek work for green, because of the greenish colour of the gas.Thorpe said of this first paper ""As a piece of induction, the memoir is a model of its kind, and as an exercise in ""the scientific use of ofthe imagination"" it has few equals.""Davy's researches on chlorine are of an importence with those on the alkali metals. Chlorine, first discovered by Scheele, was regarded by him as ""dephlogisticated muriatic acid"". As phlogistion was perfectly synonymous with hydrogen to Scheele, this view was essentially correct. Lavoisier, however, chiefly occupied with phenomena of combustion, assumed that chlorine was an oxide of an unknown ""radical"". avy performed many experiments endeavouring to confirm the presenceof oxygen and finally concluded that chlorine was an element.""(Leicester & Klickstein ""A Source Book in Chemistry"", p. 243 ff).‎

‎First German edition of this landmark paper in chemistry, in which Davy shows that electricity is capable of decomposing the most stable chemical combinations. He decomposes some alkalies, isolating two new substances and discovering potassium and sodium. Neville in his Historical Chemical Library vol. I, p.340, writes about this paper ""ONE OF THE GREAT CLASSIC RESEARCHES IN CHEMISTRY, in which Davy announced in this, his second Bakterian lecture, the isloation of metallic potassium and sodium by the electrolytic decomposition of their fused oxides.""""He (Davy) began his own electrical experiments...The results were spectacular. On October 6, 1807, the current passing through molten potash liberated a metal, which Davy called potassium. The little globules of shining metal tore the water molecule apart as it eagerly recombined with oxygen and the liberated hydrogen burst into lavender flame. Davy danced about in a delirium of joy. A week later he isolated sodium from soda.""(Asimow). The paper offered here describes these discoveries.""Humphry Davy was one of the most brilliant chemists of the early nineteenth century. His early study of nitrous oxide brought him his first reputation, but his later and most importent investigations were devoted to electrochemistry. Following Galvani's experiments and the discovery of the voltaic pile, interest in galvanic electricity had become widespread. The first electrolysis by means of the pile was carried out in 1800 by Nicholson and Carisle, who obtained oxygen and hydrogen from water. Davy began to examine the chemical effects of electricity in 1800, and his numerous discoveries were presented in his Bakerian lecture to the Royal Society on November 20, 1806.(A Source Book in Chemistry p. 243). - Wheeler Gift: 2514.‎

It was from this unpromishing material that Roscoe and Sir Edmund Thorpe laboriously prepared the pure vanadium compounds needed for a thorughout study of the element.

‎First appearance of this milestone paper in organic chemistry - a shorter note was published in Comptes Rendus in June 1858 - in which, independently of Kekulé, Couper introduces the CONCEPT OF BONDS (represented as a dash or a dotted line) in chemistry and also observes the very importent fact, that carbon atoms forms the backbone of organic compounds.""It was not till 1858 that a satisfactory theory of molecular constitution was advanced, simultaneously and endependently, by thwo young chemists, Friedrich August Kekulé and Archibald Scott Couper. 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.

In december of 1877, when Louis Paul Cailletet was about to report hisliquefaction of oxygen to the Paris Academy of Sciences, ictet cabled from Geneva that he hadachieved the same feat. Cailletet and Pictet had worked independently and by different methods. While Cailletet's method had been to compress, cool and expand the gas to be liquefied, Pictet had employed the ""cascade"" process, in which the refrigeration cycles of three different cooling media with successively lower critical temperatures were arranged in series, so that the gas liquefied in first would act as a cooolant in the liquefation of the next. ictet used sulphur dioxide in the first cycle, carbon dioxide in the second and oxygen in the last. Although Cailletet could establish a priority of a few weeks, Pictet has been allowed to share the credit for the first liquefaction of an atmospheric gas.""(DSB X, pp. 604-5).‎

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.

There was a bright yelælow line with a greener tint than that of the helium line and a brilliant green line that did nor coincide with any line of argon, helium, mercury, or hydrogen. They discoverede this gas on 30 May, 1898, and named it 'krypton'....they found that it belonged between bromine and rubidium in the periodic table, and so great was their excitement that the younger chemist almost forgot about his examination for doctor of sciwence which had been schedules for the next day.""(Weeks, p. 267).Parkinson ""Breakthroughs"", 1898 C.‎

Hofmannproved this in adetailled study, in which he showed that all hydrogens of ammonia, and even of the ammonia radical, could be replaced by organic groups to give primary, secondary, and tertiary amines, and quaternary ammonium compounds. In the course of this work, he also cleared up the relation between ammonia and the ammonium radical which had long troubles chemists. The investigation was carried out in 1850, at a time when the type theory was foremost in theminds of organic chemists. It was therefore natural that Hofmann should formulate his nes compounds as representative of the ""ammonia type"". The formulas which he wrote, however scarcely differ from those used today. These clear examples helped Frankland in developing his theory of variable valence.""(Klickstein p. 364). Klickstein's selection is taken form the offered item pp. 392-397.‎

Their study was published in 1883 (the work offered). All atomic weights were referred to the standard of unity for the atomic weight of hydrogen, a standard that Meyer championed.....In 1903 the newly created International Commission of Atomic Weeights decided to publish parallel tables based on H=1 and O=16, a practice followed for many years.""(DSB IX, pp. 351-352).‎

Dumas' name is still associated with the two procedures which he devised here, the determination of vapor density and combustion analysis.""The most important problem with which Dumas was concerned throughout his career was the classification of chemical substances. 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).‎

He found that most salts cause a fall in temperature when dissolved in water, but some...cause a rise in temperature....He discusses the theory of solution - the interpostion of salt particles between water particles, attraction, etc...""(Partington II, pp. 716-17).When Frederick the Great became king in 1740, he made Eller his personal physician and appointed him director of the Berlin Academy of Sciences. Eller’s wife died in 1751, and in 1753 he married Henrietta Catherine Rosen. In 1755 Frederick made Eller a privy councillor, a position he held until his death. Eller held the highest positions in Prussia, professor of anatomy, dean to the Collegium Medico-Chirurgicum, director of the Berlin Academy of Sciences and physician-in-ordinary to Frederick the Great.
