The averse reaction to this discovery by Mendeleev (1834 1907) might have been the main reason for his not being awarded the Nobel prize in chemistry in 1906." The discovery of argon resulted from a careful unraveling of an empirical discrepancy, initially detected by Rayleigh when measuring the density of nitrogen gas produced by two different procedures. After a long trial-and-error process based on a carefully designed sequence of experiments and guided by an informal (by today s standards) analysis of the resulting data Rayleigh and Ramsay reached the conclusion that the atmospheric air contains argon, a hitherto unknown element."--"The Discovery of Argon: a Case of Learning from Data?", by Aris Spanos in Philosophy of Science,Vol. 77, No. 3, July 2010__+__ "Rayleigh and Ramsey  had noted that nitrogen obtained from the air had a density greater than that of nitrogen liberated from its compounds by about one-half percent. This led to the isolation of the first of the inert gases which they called argon. In the following year Ramsay found another, helium, in the mineral clevite, altho this had been noted in the sun s spectrum by Lockyar  in 1868. In four years, 1894-8, five new gases, including neon, krypton and xenon had been discovered. These form a distinct group in the periodic table; all have zero valency. [Dibner].

"In 18591860 Mendeleev worked at the University of Heidelberg, where he first collaborated with Bunsen, and then established his own laboratory. He studied capillary phenomena and the deviations of gases and vapors from the laws of perfect gases. In 1860, he discovered the phenomenon of critical temperaturethe temperature at which a gas or vapor may be liquefied by the application of pressure alonewhich he called the "absolute temperature of boiling." He was thereby led to consider once again the relationship between the physical and chemical properties of particles and their mass. He was convinced that the force of chemical affinity was identical to the force of cohesion; he looked upon his work, then, as falling within the realm of physical chemistry, the ground upon which chemistry, physics, and mathematics met."--Complete DSB online.

Bound in calf-backed marbled boards (recently finely rebound). The text is very slightly browned (common to m experience with this journal and the Annalen der Physik in the 1870s), otherwise a FINE copy. [++] In this paper ( On the applicability of the periodic law to the cerite metals ) Mendeleev examines whether and how the periodic law can be applied to the so-called cerite metals, and though there were some who question the peridoic table in addressing cerium and the rare earths M treated the issue as problems in data and not a failure of theory. [++]"The reception of the periodic law caused Mendeleev considerable mental anguish. In the sharp and prolonged battle that was soon joined, the law at first had lew advocates, even among Russian chemists. Its opponents, who were especially vocal in Germany and England, included those chemists who thought in exclusively empirical terms and who were unable to acknowledge the validity of theoretical thinking; Bunsen, Zinin, Lars Nilson, and Carl Petersen were prominent among them. Petersen not only doubled the generality of the periodic law but also defended the contradictory view of the trivalence of beryllium. In Germany, Rammelsberg also look issue with a particular point, attempting in 1872 to refute Mendeleev s proposed correction for the atomic weights of cerium and its close neighbors. Mendeleev answered this charge the following year in an article [the one offered here] in which he demonstrated that the facts introduced by Rammelsberg strengthen, not refute, my proposed changes in the atomic weight of cerium. --Complete Dictionary of Scientific Biography, online.

7th edition. Dmitri Mendeleevâs Osnovy Khimii (âPrinciples of Chemistryâ) is one of the foundational texts of modern chemistry and the work through which Mendeleev articulated and defended the periodic law. This 1903 seventh edition, revised and expanded, reflects the mature state of his thinking following the international acceptance of the periodic table. The text covers elemental properties, atomic weights, chemical reactions, and systematic classification of elements, with detailed discussions of metals such as zinc, cadmium, mercury, and silver, as well as theoretical and practical laboratory chemistry. Illustrated throughout with numerous in-text diagrams of laboratory apparatus and reaction processes, the volume also contains tabular material relating to atomic weights and periodic relationships. An engraved portrait of Lavoisier appears at the front, underscoring the workâs historical and scientific lineage. As a late lifetime edition (Mendeleev died in 1907), this printing represents an important authoritative version of his landmark treatise. Rare Book Hub (RBH) shows no copies of this title that have sold in the last century. In addition and extraordinarily OCLC shows no copies of this book in any world libraries, although it must exists as e-copies are available in various libraries. Suffice to say, this book is an extraordinary rarity. An important aspect of this book is that it provided Mendeleev's final periodic table as he was to die soon after publication. Kaji (Bulletin History of Chemistry, Vol 27, 2002) writes about how this book dealt with rare earths in its group IV of the final periodic table: "By the seventh edition of 1902-1903 Mendeleev had abandoned N3 and fully accepted the noble gases, which he incorporated into the chapter on nitrogen and air. Mendeleev asked the Czech chemist Bohuslav Brauner (1855-1935) to write the section on the rare earths for the seventh and eighth editions, even though they had somewhat different opinions on the positions of these elements within the periodic system. They agreed to place scandium, yttrium, and lanthanum in the third group andÂtantalum in the fifth.ÂHowever, whileÂMendeleev believedÂthat future researchÂwould reveal sufficientÂnumbers ofÂrare earth elementsÂwith different properties,Âso they couldÂbe placed in differentÂgroups to fit neatlyÂinto his periodicÂtable, Brauner proposedÂthat the rareÂearths should be allÂplaced together inÂgroup IV, which wasÂformerly occupiedÂby cerium alone."

This volume also contains a second paper by Mendeleev relating to his periodic law: ["On the Correlation between the Properties of the Elements and Their Atomic Weights", Zhurnal Russkoe Fiziko-Khimicheskoe Obshchestvo, Vol. 1, pp. 229-30. There were 5 issues in volume I, numbered 1, 2/3, 4/5, 6/7, 8/9. Each issue was published with a title page, with the contents for that issue printed on the verso of the title page. In addition there was a leaf with publisher's ads at the end of each issue. IMPORTANT NOTE: This copy of volume I does have the title page for the entire volume, as well as a separate contents leaf for the entire volume, and the index and errata leaf for the entire volume. But the title pages and ad leaves for the individual issues were discarded when the issues were bound up into this volume. Mendeleev's first publication of his periodic law was a single-page flyer with the title "An Attempted System of the Elements Based on Their Atomic Weights and Chemical Analogies". There were 150 copies printed in Russian and 50 copies in French. Mendeleev's paper offered here was read to the March 1869 meeting of the recently founded Russian Chemical Society. I use the passive voice because Mendeleev himself did not read his paper. Contrary to the frequently-encountered statement that he did not do so because he was ill, Mendeleev was away on an inspection of cheese-making operations. The paper was read for him by his friend Nikolai Menshutkin. The paper was then published in April 1869 in vol. I of the journal of the Russian Chemical Society. Mendeleev's textbook of inorganic chemistry, Osnovy knimii, was published in 2 volumes in 1869 and 1871. His extensive discussion of the periodic law is in volume II. However in the Preface to volume I, dated March 1869, Mendeleev's periodic table is printed. This table is the same as the one in Mendeleev's flyer. The periodic table in the paper offered here is slightly revised from its original version in the flyer and the Preface to volume I of the textbook. I do not know if volume I of the textbook was available before or after the April 1869 issue of the Journal of the Russian Chemical Society. An offprint of the paper offered here does exist and is dated St. Petersburg, March 23, 1869 (this is according to Jonathan Hill's cataloguing of a copy of the offprint). The offprint has a drop-title on page [1] stating that the article appeared in the Journal of the Russian Chemical Society, pp. 60-77. 47 members of the Russian Chemical Society are listed on pp. 4-5 of volume I. Mendeleev is included on p. 4. It has been stated that only 80 copies of volume I were published. With only 47 members in the Society, that number seems reasonable, although I cannot confirm it. Mendeleev's paper is Grolier, One Hundred Books Famous in Science (Horblit) 74. NOTE about photos: I can supply more photos of the binding upon request.

Hardcover. Condition: Very Good. No Jacket. 5th or later Edition. SCARCE 1895 RUSSIAN EDITION OF MENDELEEV'S SEMINAL BOOK COVERING THE PERIODIC TABLE OF ELEMENTS. Mendeleev originally wrote Osnovy Khimii to provide a text for his lectures. The book's chapters include discussions of the relation of atomic weights to the physical and chemical properties of elements. It was only shortly before publication that Mendeleev Osnovy Khimii that Mendeleev realized how to group the elements according to the principle of atomicity. This happened after Mendeleev had been appointed to the chair of chemistry in the University of St. Petersburg. Finding there was no book he could recommend to his students as a text for his lectures, he set out to write his own, deriving his basic plan from Gerhardt's theory of types, whereby elements were grouped by valence in relation to oxygen. BOOK DETAILS: Royal 8vo, cont. cloth (probably original) with leather label on spine; soiled on covers including cup ring but VG internally. This 6th Edition is nearly a reprint of the considerably expanded 5th Edition (1889), includes some revised footnotes and also includes Mendeleev s first printed commentary on the Rayleigh-Ramsay discovery of Argon. This is a very significant problem for Mendeleev since Argon s atomic weight is virtually identical to that of Calcium and there is simply no room for it in the periodic table. Mendeleev suggests it might actually be N3. The 2nd English edition (1897) is the translation of this 6th Russian Edition. RARITY: The Girolami/Mainz catalogue cites eight copies documented by WorldCat and KVK as well as this copy, the copy of Girolami/Mainz and one offered by Henry Sotheran Ltd in 2014 for 2,750 pounds sterling ($4,625). Interestingly, no copies of this edition have come up for auction in the last century (RBH). PROVENANCE: From the Arthur C. Greenberg Chemistry History Library.

Hardcover. Condition: Good. No Jacket. 1st Edition. Large 8vo. First Edition of Mendeleev s translation of Charles Gerhardt and Gustave Chancel's book Prà cis d'Analyse Chimique Qualitative (Second Edition, Paris, 1862; see Bolton p 476). Original ½ leather over textured cloth boards, very worn, printed spine title faded but clearly visible: vi, 547 pp, includes 149 woodcuts as well as tables; first blank, title page and first leaf of contents table missing small section upper right corner from scorching but not affecting text. From Gregory S. Girolami and Vera V. Mainz Collection of Rare Books in Science: Although through most of the book figures and figure numbers correspond to those in the 1862 French edition, there are departures (e.g. Figures 41a-e after Figure 41 and Figure 42 matching the 1862 edition). There are more departures toward the end. Most striking is that the Mendeleev translation ends without the Appendix on spectrometry in the 1862 French edition. In its place the Mendeleev translation expands the crystallography section including extra woodcuts. RARITY: This book is extremely rare. Unfortunately, many Russian books did not survive in the country after the 1917 Revolution. Worldcat and KVK list three copies of this book: National Library of Israel, Helsinki University, and National Research Council of Canada in addition to copies in the Giralomi/Mainz collection and this one (from the Arthur C. Greenberg History of Chemistry Library). Light foxing but overall G. Vera Mainz (Preceptors in Chemistry, ACS, 2018): "Dmitrii Ivanovich Mendeleev (1834-1907) is best known for his discovery in 1869 of the periodic law of the chemical elements, leading to the concept of the periodic table. Many, including Mendeleev, ascribe this discovery to his work in writing a general chemistry textbook for the Russian student, Osnovy khimii or The Principles of Chemistry. What is less well known is that the Principles was one of several chemistry textbooks Mendeleev wrote for a Russian audience. Among these were Organicheskaia Khimiia (1861), an organic chemistry textbook, and Analiticheskaia Khimii (1864), a translation of Charles Gerhardt and Gustave Chancel's Prà cis d'analyse chimique qualitative (1862), both of which appeared prior to the publication of the Principles. More than anyone else, Mendeleev brought the modern chemistry textbook written in the Russian language to Russia." (DOI: 10.1021/bk-2018-1273.ch008).

INTRODUCING THE PERIODIC TABLE TO THE WESTERN WORLD: FIRST EDITIONS OF TWO KEY PAPERS RELATING TO MENDELEEV'S DISCOVERY OF THE PERIODIC LAW-ONE OF THE MOST IMPORTANT DISCOVERIES IN MODERN CHEMISTRY. One of the most consequential scientific discoveries of the last 150 years was Dmitri Mendeleev's realization that if the chemical elements were listed in a natural order (originally by atomic weight, and later by atomic number), then the list could be broken down into rows and displayed in the form of a table in which the elements within each column of the table had similar chemical properties. The resulting tabular display of the elements is now known as the periodic table. Mendeleev explained the ability to construct such tables in terms of a general principle that chemical properties change periodically as one moves along the ordered list of elements. This insight had an important immediate consequence: it facilitated the identification of gaps in the list of known elements, and enabled chemists to predict the properties of the elements that would later be discovered to fill those gaps. Even more importantly, periodicity stimulated other theoretical advances. As E.R. Scerri notes: "Whenever scientists are presented with a useful pattern or system of classification, it is only a matter of time before they begin to ask whether there may be some underlying explanation for the pattern. The periodic system is no exception." (The Periodic Table, p. xix). Thus, the periodicity of element's chemical properties found a natural explanation in Bohr's 1913 proposal of a "quantum" model of the atom in which electrons were arranged in concentric "shells," each with a characteristic fixed size. As atomic number increased, so did the number of electrons in an atom. The additional electrons were added to the outermost shell one-by-one until it was full, and then they began occupying a new outer shell. The atoms of chemically similar elements were postulated to have the same number of electrons in their outer shells. In turn, that insight led to later developments in quantum theory-such as the Pauli exclusion principle and the spin-statistics theorem-which provided an explanatory framework for, and refined, Bohr's "shell" model. Like all prescient discoverers, Mendeleev stood on the shoulders of giants. The organization of the elements into groups with similar properties goes back to at least the eighteenth century, and some chemists had experimented in the 1860s with tabular arrangements of elements listed in order of increasing atomic weight (see Edward G. Mazurs, Graphic Representations of the Periodic System during One Hundred Years, ch. 1). Lothar Meyer, for example, drew a periodic table in 1868 but did not publish it. It was Mendeleev, however, who in 1869 announced the periodic law as the natural principle underlying such tables: "Mendeleev] is by far the leading discoverer of the [periodic] system. Although he was not the first to develop a periodic system, his version is the one that created the biggest impact on the scientific community at the time it was introduced and thereafter. His name is invariably and justifiably connected with the periodic system, to the same extent perhaps as Darwin's name is synonymous with the theory of evolution and Einstein's with the theory of relativity. "Although it may be possible to quibble about certain priority aspects of his contributions, there is no denying that Mendeleev was also the champion of the periodic system in the literal sense of propagating the system, defending its validity, and devoting time to its elaboration." (Scerri, The Periodic Table, p. 101). Mendeleev's discovery was initially announced in a paper read before the Russian Chemical Society in St. Petersburg in 1869, and published the same year in the Journal of the Russian Chemical Society (Zhurnal russkago khimicheskago obshchestva). However, it is the two works offered here that put the discovery before the eyes of chemists in western Europe and America. These works are: 1. An abstract, in German, of Mendeleev's 1869 paper. "The German abstract, which contains a version of the periodic table, was the first announcement of Mendeleev's discovery published in Western Europe." (The Haskell F. Norman Library of Science and Medicine, ed. Diana H. Hook and Jeremy M. Norman, 2 vols. (San Francisco: J. Norman, 1991), 1491). The original paper "was not translated from Russian until 1895 and consequently played little or no role in initially acquainting American, British and western European chemists with the periodic law. This role was played instead by two short German abstracts of the paper, one of which appeared in the Journal für praktische Chemie and the other in the Zeitschrift für Chemie {The latter is the one offered here.} [.] The first reproduced only Mendeleev's table, without any commentary or explanation [.] To the best of our knowledge, only the longer abstract in the Zeitschrift für Chemie had a significant impact, as it was the reading of this abstract that stimulated the German chemist, Lothar Meyer, to publish his own thoughts on the periodic law in late 1870 and which ultimately gave rise to a vigorous priority debate." (William B. Jensen, "Origins of the Period Law, 1869-1871", in Dmitri Ivanovich Mendeleev, Mendeleev on the Periodic Law: Selected Writings 1869-1905, ed. Jensen (Cincinnati: University of Cincinnati Press, 2002)). 2. The first complete and detailed presentation of the periodicity principle, and Mendeleev's first use of the term "periodic" to describe that principle. "It was in this article that Mendeleev spelled out his detailed predictions [of the properties of as-yet unknown elements] that, when later confirmed, were to make him famous." (Scerri, The Periodic Table, p. 112). Mendeleyev himself characterized this paper as "the best summary of my views and ideas on the periodicity of the elements and the original after which so much was written later about thi.

Mendeleev, who conceived of a stratospheric balloon and devised plans for its construction in 1875. The first foreigner to construct a stratospheric balloon was Picard in 1931. In 1887, Mendeleev ascended 3,350 meters in the balloon to observe a solar eclipse. Mendeleev defined the future significance of aviation with great foresight.

1st Edition. FIRST EDITION OF THE FIRST OF MENDELEEV'S PREDICTED ELEMENTS TO BE IDENTIFIED, thereby confirming "the validity of the periodic system of elements" Mendeleev had designed (Niaz, Critical Appraisal of Physical Science, 62). "The confirmation of this prediction may certainly be called the culminating point in the history of the periodic system" (ibid). In 1869 "Mendeleev published a periodic table. Mendeleev also arranged the elements known at the time in order ofrelative atomic mass, but he did some other things that made his table much more successful. He realised that the physical and chemical properties of elements were related to their atomic mass in a 'periodic' way, and arranged them so that groups of elements with similar properties fell into vertical columns in his table. "Sometimes this method of arranging elements meant there were gaps in his horizontal rows or 'periods'. But instead of seeing this as a problem, Mendeleev thought it simply meant that the elements which belonged in the gaps had not yet been discovered. He was also able to work out the atomic mass of the missing elements, and so predict their properties. And when theywerediscovered, Mendeleev turned out to be right. "The discovery of the three elements predicted by Mendeleev was of decisive importance in the acceptance of his law. In 1875 Lecoq de Boisbaudran, knowing nothing of Mendeleev's work, discovered by spectroscopic methods a new metal, which he named gallium. Both in the nature of its discovery and in a number of its properties gallium coincided with Mendeleev's prediction for eka-aluminum, but its specific weight at first seemed to be less than predicted. "Although Lecoq de Boisbaudran objected to this interpretation, he made a second determination of the specific weight of gallium and confirmed that such was indeed the case. From that moment the periodic law was no longer a mere hypothesis, and the scientific world was astounded to note that Mendeleev, the theorist, had seen the properties of a new element more clearly than the chemist who had empirically discovered it. From this time, too, Mendeleev's work came to be more widely known" (Dictionary of Scientific Biography). CONDITION & DETAILS: Complete volume.

(Mendeleev is spelled Mendelejeff here with the running title of "M.D. Mendelejeff on the discovery of Gallium".) The supplement is complete in 6 unbound signatures which are also uncut and unopened. Scarce in this format. [++] The Mendeleev paper was printed in 1876 a year after Lecoq de Boisbaudran's discovered gallium (Mendeleev's predicted "eka-aluminium"). Boisbaudran's paper appeared in "Comptes Rendus de l'Academie des Sciences", vol 81, No 12; a longer and more complete paper appeared in 1877 in "Annales de Chimie et de Physique". [++] In this paper Mendeleev wrote on how Gallium's properties were a very close fit to what his table predicted they would be, therefore providing strong experimental evidence for the validity of the periodic table. (His paper in English follows closely the French appearance of "Remarque à propos de la découverte du gallium" in the "Comptes Rendus" vol 81, 1875, pp. 969-972 .) "In 1875 Boisbaudran spectroscopically discovered a new element, gallium, which he found in zinc blend from a mine in Hautes-Pyrénées. Continuing his work in Wurtz's laboratory in Paris, he was a able to obtain the free metal by electrolysis of a solution of the hydroxide in potassium hydroxide. Gallium, Boisbaudran realized, was the "eka-aluminum" predicted by Mendeleev, and was the first of Mendeleev's predicted elements to be isolated. Boisbaudran's finding thus provided valuable evidence for the validity of Mendeleev's periodic classification of the elements."--Complete DSB online. [++] "Although Lecoq de Boisbaudran objected to this interpretation, he made a second determination of the specific weight of gallium and confirmed that such was indeed the case. From that moment the periodic law was no longer a mere hypothesis, and the scientific world was astounded to note that Mendeleev, the theorist, had seen the properties of a new element more clearly than the chemist who had empirically discovered it. From this time, too, Mendeleev's work came to be more widely known".--Complete DSB online.

Folio. Autograph manuscript. 24 ff., some leaves written on both sides. Revised by the author throughout. Stored in custom-made blue half morocco solander case. The original manuscript of Mendeleev's speech on "The Oscillation of the Balance", delivered at the General Meeting of the 10th Congress of Russian Naturalists in Kiev (August 1898). In his annotated bibliography of his own works, self-compiled in 1899, Mendeleev writes: "Predmet schitaju ochen' vazhnym i interesnym" ("A subject I find very important and interesting"). After the end of his teaching career at the University of St. Petersburg in 1890, Mendeleev was variously employed by the government bureaucracy. From 1892 on he was "concerned in the regulation of the system of weights and measures in Russia, a task that he discharged 'with enthusiasm, since here the purely scientific was closely interwoven with the practical.' In 1893 he was named director of the newly created Central Board of Weights and Measures, a post which he held until his death, and in connection with which he frequently traveled abroad" (DSB IX, 292). - "The great importance of Mendeleev's work", write Kayak and Smirnova, "was that in his approach to the development of the theory of balances and methods of accurate weighing he took into account the physical essence of the phenomena investigated, whereas many investigators before and even after him attempted to solve all the problems on the basis of purely mechanical conceptions [.] Mendeleev's interest in balances as the most important instrument in physical and chemical investigations was manifested from the very beginning of his scientific work. Long before his move to the Depot of Standard Weights and Measures he devoted much attention to the perfection of balances, and methods of accurate weighing. In 1861 Mendeleev succeded in observing the oscillations of balances from a distance, thereby eliminating the influence of the heat radiated by the observer on the balance; he also proposed the use of a heat distributor made of copper for a balance beam. Mendeleev's most important work on the development of the theory of balances and methods of accurate weighing was made at the Principal Bureau of Weights and Measures, where he took upon himself the entire responsibility for organizing and equipping the weight laboratory" (p. 25). - Occasional insignificant edge defects, but altogether a very well preserved manuscript.
