With an illustration of the apparatus in the text. <br/><br/><em>First printing of these two milestone papers in Low-temperature Chemistry. This process of liquefaction of oxygene was achieved independently in the same year by Cailletet and Pictet using different methods. Cailletet used the Joule-Thomson effect; oxygen was cooled while highly compressed then allowed to rapidly expand cooling it further resulting in the production of small droplets of liquid oxygen. Pictet's method was more elaborate using compounds pumps. This compound is shown on the illustration in the text.Parkinson "Breakthroughs" 1877 C. - Magee "Source Books in Physics" p. 192-93 Cailletet and pp. 194-96 Pictet. </em> unknown

Couper's paper: pp. 1157-1160. A faint dampstain to right margins. <br/><br/><em>First appearance of this milestone announcement in organic chemistry - a longer memoir was published in "Annales de Chimie et de Physique" later in the same year 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. </em> unknown

Clean and fine. <br/><br/><em>First appearance of Faraday's first breakthrough in chemistry as he here synthesized for the first time chloro-carbons."In 1820 he Faraday produced the first known compounds of chlorine and carbon C2Cl6 and C2Cl4. These compounds had been produced by the substitution of chlorine for hydrogen in "olefiant gas" our modern ethylene. This was the first substitution reaction; such reactions in the hands of Charles Gerhardt and August Laurent in the 1840's were to be used as a serious challenge to the dualistic electrochemical theories of J.J. Berzelius." DSB IV p. 531.Parkinson "Breakthrough" 1820 C. </em> unknown

Wöhler's paper: pp. 157-172. <br/><br/><em>First printing of Wöhler's importent paper in which he in reality for the first time synthezised an organic substance leading to his historic preparation of "artificial" urea in 1828 "Ueber künstliche Bildung des Harnstoffs". This broke down the old distinction between organic and inorganic substances. "This was the first synthesis of an organic compound and this accomplishment is generally regarded as the beginning of organic chemistry."Sparrow "Milestones of Science" p.37 the 1828 paper."In his published paper the 1828 paper Wöhler referred to his work of 1823 the offered paper in which he had shown that cyanogen and aqueous ammonia yielded oxalic acid and a white crystalline solid that he now realized was urea. This and his new method he considered to be remarkable examples of the preparation "by art" of a substance of animal origin from inorganic materials."DSB.The volume contains other notable papers BECQUEREL: "Ueber die Electricitäts-Erregung durc Druck nach versuchen des herrn becquerel; ein bericht abgestatt. von Biot.
