‎Chimie appliquée à la physiologie [Suivi de] Physiologie comparée [in Revue des cours scientifiques. Première année - n° 21]‎

‎Paris, Germer-Baillie?re [impr. E. Martinet], 23 avril 1864, in-4, [16] pp. (pagination de 257 à 272), Broché, sans couverture, Édition originale de ce numéro de la future Revue rose, où sont confrontées les ultimes démonstrations de Pasteur et de Pouchet dans la querelle qui les opposa au sujet de la génération spontanée entre 1859 et 1865. Cette livraison comporte en effet, l'un à la suite de l'autre, la démonstration de Pasteur faite lors des Soirées scientifiques de la Sorbonne le 7 avril 1864, et le cours de Pouchet donné au Muséum d'histoire naturelle de Rouen. Le premier infligea un coup de grâce au second en démontrant devant une "brillante assemblée", composée entre autres d'Alexandre Dumas et George Sand, que la génération spontanée des êtres n'est qu'une "chimère". "(...) faisons la nuit autour de nous, rendons tout obscur, et éclairons seulement ces petits corps, alors nous verrons comme le soir on voit les étoiles" (Pasteur, p. 261). Félix Pouchet (1800-1872), correspondant de l'Institut et fondateur du Muséum d'histoire naturelle de Rouen, défendait l'idée, déjà ancienne, de l'ovulation spontanée des mammifères. En 1859, il publie Hétérogénie, ou Traité de la génération spontanée, dans lequel il reprend à son compte cette théorie. Au même moment, Louis Pasteur (1822-1895) démontrait au contraire la fermentation et la biogenèse. L'Académie des Sciences établit une commission chargée de trancher le débat. Pasteur, qui réalise des expériences avec ses fameux ballons à col de cygne, parvient à démontrer que la contamination microbienne provient de l'air, et non de la génération spontanée à partir de matière inanimée ("Mémoire sur les corpuscules organisés qui existent dans l'atmosphère", Annales de chimie et de physique, 3e série, vol. 64). De leur côté, les partisans de Pouchet jugent la commission partiale et renoncent à s'y présenter; Pasteur remporte donc le prix en 1862. Face à la contestation, l'Académie constitue une seconde commission le 4 janvier 1864. Le 7 avril, Pasteur présente ainsi à la Sorbonne la démonstration retranscrite ici. Il y conclut : "Non, il n'y a aucune circonstance aujourd'hui connue dans laquelle on puisse affirmer que des êtres microscopiques sont venus au monde sans germe, sans parents semblables à eux. Ceux qui le prétendent ont été le jouet d'illusions, d'expériences mal faites, entachées d'erreurs qu'ils n'ont pas pu apercevoir ou qu'ils n'ont pas su éviter" (p. 265). Pouchet, à Rouen, présente son cours de physiologie sur les générations spontanés; il y soutient que les expériences chimiques de Pasteur rétrogradent la science d'un siècle et invoque les expériences physiologiques qui soutiennent, au contraire, la thèse de l'hétérogénie, en démontrant l'absence de germes dans l'air (les "oeufs atmosphériques"). La commission conclut, le 20 février 1865, en faveur de Pasteur. Ce résultat a eu un impact significatif sur la compréhension de la microbiologie et de la médecine; il est le premier pas de Pasteur vers la formulation de la théorie microbienne des maladies. Pouchet restera quant à lui convaincu de sa théorie, jusqu'à sa mort. Numéro tel que paru, sans couverture et sans attache. Couverture rigide‎

‎First appearance in French of Liebig's two papers on fermentation and first appearance of Pasteur's paper. Liebig's papers started a bitter controversy (after Liebig's death continued by Claude Bernard) as he claimed, that all ferments are chemical reactions and not vital processes. Pasteur, on the other hand, claimed that life is needed for fermentation.""From 1865 to 1870, while Pasteur was preoccupied with the silk-worm problem, his theory of fermentation enjoyed increasing favor, especially abroad. What criticism did appear during the period failed to distract him from his centraltask. In 1871, hovever, the ""Annales de chimie et de physique"" published a French translation of a wide-ranging critique by Liebig (the papers offered), who had broken a long silence on the issues of the two lectures (1868, 1869). In a reply (the paper offered) of almost arrogant brevity, Pateur discussed only two aspects of Liebig's critique, both of which involved direct challenges to experimental claims made a decade beforee by Pasteur: (1) that pure yeast and a simple alcoholic fermentation could be produced in a medium free of organic nitrogen and (2) that acetic fermentation required the intervention of ""Mycoderma aceti"". OPasteur responded by challenging Liebig to submit the dispute to a commission of the Academie des Sciences. before this commission, Pasteur boldly predicted, he would prepare, in a medium free of organic nitrogen, as much beer yeast as Liebig might reasonably demand and would demonstrate the existance of ""Mycoderma aceti"" on the surface of the beechwood shavings used in the German methpd of acetification....Liebig died in 1873 without accepting Pasteur's challenge.""(DSB X, ppp. 376 ff.). - Partington IV, pp. 307 ff.The volumes contains other notable papers: BERTHELOT ""Mémoire sur la force de poudre et des matieres explosives"", pp. 223-273., JANSSEN: ""Études sur les raies telluriques du spectre solaire"", pp. 274-298, KEKULÉ, BOUSSINGAULT, STAS, WURTZ et al.‎

‎First appearance of a milestone paper in chemistry in which Pasteur announced two momentous importent discoveries, that racemic acid could be separated into the two optically active tartaric acids and the discovery of ""mesotartaric"" acid.For his work on racemic acid and crystallography he received the prize of 1,500 francs from the Société de pharmacie (1853), membership in the Legion of Honor, and the Rumford Medal of the Royal Society (1856).""During this journey (travel to Vienna, Prag and Saxony) Pasteur met a German industrial chemist who claimed to have achieved what Pasteur then considered impossible - the chemical transformation of tartaric into racemic acid. Although he soon confirmed his belief that this particular claim was inaccurate, Pasteur unexpectedly achieved the transformation in May 1853 by heating cinchonine tartrate at 170°C. for five to six hours. This procedure also yielded a small amount of inactive ""mesotartaric"" acid, the existence of which Pasteur had predicted the year before and in search of which he had apparently undertaken the experiment. In the memoir (1 August 1853) in which he announced these two discoveries, Pasteur disclosed a new method for separating racemic acid into its left- and right- handed components. His original method, involving the manual separation of the crystals, was laborious and extremely limited in applicability. The central feature of the new method was the chemical combination of racemic acid with optically active bases. Under appropriate conditions they affected the solubility of the resulting paratartrates in such a way as to favor the crystallization of only one of the two forms that together compose the paratartrate. Although introduced by Pasteur only for the case of racemic acid, this new method clearly had wider applicability and was soon used to separate the left- and right- handed components in other ""racemic"" substances (substances inactive by compensation).""

A few marginal brownspots to P.'s paper. Otherwise fine and clean.‎

‎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. Pp. 203-229.‎

A more full exposition was published the same year in ""Annales de Chimie et de Physique"", 3me Series - Tome XXIV.""In 1848....Pasteur studied the crystals of tartrates (one of the substances that exhibited the now-clockwise, now-counterclockwise effect) under the microscope and found that the xcrystasls were mirror images of the others. The two crystals resemmbled each other as a right-hand glove resembles a left-hand glove....This was a revolutionary discovery and it took some courage to announce it. A few years before, the well-known chemist Mitscherlich had studies the same tartrate crystals and declared them all to be identical. Pasteur was only a twenty-sic-year-old unknown. neverthelless he announced his findings and went before Biot to repeat the separation ofthe crystals before the eyes of the aged authority in the field. Biot was convinced and Pasteur received the Rumford medal of the Royal Society for his work....Pasteur had thus founded the science of polarimetry in which the measurements of the manner in which the plane of polarized light was twisted could be used to help to determine the structure of organic substance, to follow various chemical reactions, and so on.""(Asimov).
