‎Ueber die Verbindungen des Alkohols mit Wasser. Im Auszuge aus d. russischen Originalarbeit von Victor Richter. (On the Compounds of Alcohol with Water). (2 Theile).‎

‎Leipzig, Johann Ambrosius Barth, 1869. Conemp. hcalf. 5 raised bands, gilt spine and gilt lettering to spine. A few scratches to spine. Small stamp on verso of first -and general- titlepage and small stamps to verso of plates. In: ""Annalen der Physik und Chemie. Hrsg. von J.C. Poggendorff"", Fünfte Reihe Bd. 18 (138. Bd. der Reihe). X,652 pp. a. 6 folded plates (The entire volume offered). Mendeléev's paper: pp. 103-141 a. pp. 230-279. Clean and fine.‎

‎First German edition of Mendeléev's doctoral dissertation ""O soedineni spirta s vodoyu"" from 1865. ""In it he first developed the characteristic view that solutions are chemical compounds and that dissolving one substance into another is not to be distinguished from other forms of chemical combination. In this thesis, he also adhered to the principles of chemical atomism.""(DSB). - This work contributed to the birth of a popular legend, which claims that Mendeleev invented the standard for Russian vodka, saying it should contain 40% of alcohol by volume. Mendeléev is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.The volume contains other notable papers by Kohlrausch, Fizeau, Zöllner etc. and Julius Thomsen's ""Thermochemische Untersuchungen""‎

‎Scarce first edition of this importent work which is a large extension of Meyer's classic paper of 1870, in which he independently of Mendeleev, discovered that the properties of the elements are a periodic function of (or vary in a periodic manner with) the atomic weight - the Periodic Table.""The significance of atomic weights in the demonstration of chemical periodicity, and the suspicion that some atomic weights were not accurate, led Meyer and Seubert to examine critically and to recalculate all atomic weights then considered importent. 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).‎

‎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.‎

The mixture was needed because hydrogen fluoride is a non-conductor. The device was built with platinum/iridium electrodes in a platinum holder and the apparatus was cooled to -50 °C. The result was to completely isolate the hydrogen produced from the negative electrode from the fluorine produced at the positive one.This is essentially still the way fluorine is produced today.""

‎First apperance of these 4 papers relating his discovery of INVISIBLE ""CHEMICAL"" RAYS, and which, 30 years later, by Henry Becquerel was ""re-discovered"" as radioactivity (1896).The results of these investigations lead to these statement: Some compounds exposed to light exhibit in the dark the same effect as that produced by the direct action of light. - Cardboards impregnated with both uranium nitrate and tartaric acid are ""active"" - The ""activity"" remaining on the exposed cardboard is revealed by its action on a photographic plate - The effect is not due to phosphorescence - The activity is attributed to invisible ""chemical"" rays.It is amazing how closely these experiments resembled those performed by Henri Becquerel 30 years later.""When the work of Abel Niepce de Saint-Victor was brought to light, many persons thought that henri had been aware of these publications prior to his research on uranium. Severel facts seems to support this belief. Henri's father, Alexandre Edmond, had reported several details from Abel Niepce in a book entitled ""Light: its causes and effects"", published 1869. When Henri Carrington Bolton (1843-1903) reviewed in 1869 the work of Abel Niepce, he mentioned a ""remarkable property of uranium nitrate to absorb the actinic rays of light, retaining them in an active condition for a long time"". In 1866 and 1869, J. Jamin, henri's first stepfather, lectured at the Ecole Polytechnique on the Niepce effects.""(Michel Genet ""The Discovery of Uranic Rays: A short Step for Henri Becquerel but a Giant Step for Science"" in Radiochimica Acta /0/71 1995).‎

‎First printing of this paper in which he described his invention of the so-called ""HELIOCROMS"", a pioneer paper in the development of colour-photography. Niepce de Saint Victor discovered there was a connection between the color that chloride salt produced in a flame with the color light produced on a chloride salt-treated plate. Heliochrome was the name of this process, which enabled Mr. Niepce de Saint Victor to produce copies of color engravings and landscapes. He did not produce daguerreotypes, and soon learned that the images he produced using the heliochrome process were not fixed and began turning gray with increased light exposure. Applying transparent coatings did not prove effective, and therefore Mr. Niepce de Saint Victor soon abandoned this unfeasible method. However, his experiments with heliochrome did lead to the successful daguerreotype color process developed by a New York Baptist minister named Levi L. Hill (1816-1865).‎

It was discovered in 1879 by Lars Fredrik Nilson.... Nilson extracted 63 grams of the rare earth erbia from gadolinite and euxenite, and converted it into the nitrate. Upon decomposing this salt by heat, as Marignac had done, he obtained some very pure ytterbia and, to his great surprise, an earth that was unknown to him.Upon thoroughly investigating this new earth, he found that it contained an element whose properties concided almost exactly with those Mendeléef had predicted for ekaboron.

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).
