‎First German edition of this classic paper in chemistry in which Berzelius presented his system of nomenclature to the scientific world. The paper was first preseted in French ""Essay sur la nomenclature chimique"" in Journal de Physique the year before (1811).""Of his contributions, moreover, to the development of the atomic theory and the advancement of chemical science, not the least valuable was the introduction of a chemical symbolism which, with slight modifivcations, is in use at the present day. By giving his symbols a quantitative meaning - the symbol of an element representing one atomic proportion by weight - it was possible ""to show briefly and clearly the number of elementary atoms in each compound and, after the determination of their relative weights, present the results of each analysis in a si8mple and easely retained manner."". This symbolism was speedily adopted on the Continent but, en England, only after some considerable time.""(Findley ""A Hundred Year of Chemistry"", p. 14). - Holmberg, Bibliografi öfver Berzelius, 1812:7).‎

‎The papers represents one of the first announcements of Berzelius' discovery of the fixed chemical proportions, determining the weights and valencies of the various constituent elements in inorganic compounds. The papers were published at the same time in Swedish, German (both here in Annalen and in Schweiger's Journal), and in French. By running many hundreds of analysis of chemical compounds he gave so many examples of the law of definite proportions that the world of chemistry could no longer doubt its validity, and in so doing he gave experimental evidence to the atomic theory. He hereby laid a solid fundation for the further development of chemistry. A reprint is found in Ostwald's Klassiker der exakten Wissenschaften, No. 35.According to Söderbaum (Jac. Berzelius, 2, p.12) ""It was a giant work, one of the most importent in the history of chemistry, which was here presented. One is even more impressed when one remembers that it was a pioneer undertaking in every sense of the term. Analytic and synthetic methods existed before Berzelius' time, to be sure, but there were no precise methods of the sort which he required. They all had to be elaborated at the cost of time and labour.""(J. Erik Jorpes ""Jac. Berzelius"", p.45).""In general Berzelius's efforts were directed toward the consolidation and extension of the atomic theory. He improved chemical analysis and determined the composition of a large number of compounds, thus verifying the laws of constant and multiple proportions and furnishing the most accurate equivalent weights then available. By ingenious methods he arrived at the correct atomic composition of most common substances, and thus was enabled to draw up (in 1826) a table of atomic weights very nearly identical with the modern one.""(Leicester & Klicktein ""A Source Book in Chemistry"", p. 258).Parkinson ""Breakthroughs"", 1810-20 C.‎

‎ First printing of these milestone papers in the history of chemistry, where Berzelius introduced his famous chemical symbolism whereby an element is generally represented by the first letter of its Latin name, or, in the event of elements having the same first letter, by the first two letters. Even though his atomic symbols were introduced in 1813 (see the note on p. 359 in the first paper), it was quite a few years before Berzelius's symbols were adopted by the chemistry community. But once accepted, they became the new international language of chemistry.Berzelius ""contributed more to the development of the atomic theory and to the setting up of accurate values of the atomic weights than did any other worker of the time.

‎First German printing - printed simultaneously with the English and Swedish version - of the paper in which Berzelius described his discovery of Thorium, the first element after Uranium to be identified as such. In 1829, Jöns Jakob Berzelius of the Royal Karolinska Institute, Stockholm extracted thorium from a rock specimen sent to him by an amateur mineralogist who had discovered it near Brevig and realised that it had not previously been reported. The mineral turned out to be thorium silicate, and it is now known as thorite. Berzelius even produced a sample of metallic thorium by heating thorium fluoride with potassium, and confirmed it as a new metal. He called the black mineral thorite, in honor of the Scandinavian god Thor.Parkinson ""Breakthroughs"", 1829 C.‎

‎First edition of this milestone work in astronomical obeservation, where Bessel reduced the observations for the ""personal equation"" based on Bradley's observations and here published Bradley's Greenwich observations for the first time and making a catalogue of 3222 stars extracted from them.""The positions of Bradley’s stars valid for 1755 were published by Bessel as Fundamenta astronomiae pro anno 1755 (1818). This work also gives the proper motions of the stars, as derived from these observations of Bradley, of Piazzi, and of Bessel himself. It constitutes a milestone in the history of astronomical observations, for until then positions of stars could not be given with comparable accuracy: through Bessel’s work, Bradley’s observations were made to mark the beginning of modern astrometry. During this investigation Bessel became an admirer of the art of observation as practiced by Bradley"" and because Bradley could not evaluate his own observations, Bessel followed and also taught the principle that immediately after an observation, the reduction had to be done by the observer himself. Further, he realized that the accurate determination of the motions of the planets and the stars required continuous observations of their positions until such motions could be used to predict ""the positions of the stars .... for all times with sufficient accuracy.""

‎First appearance of a milestone paper in astronomy, giving the solution of the great problem of distances in the universe which had baffled astronomers ever since the time of Copernicus, announcing the FIRST SUCCESSFUL DISPLACEMENT OR PARALLAX OF A FIXED STAR and hence deducing the FIRST RELIABLE DISTANCE OF THE EARTH TO A FIXED STAR. The parallax observed corresponded to ab. 600.000 times that of the earth from the sun. On these grounds Bessel calculated the distance to about 11 light years, and this was confirmed by fresh investigations by Bessel in 1839-40 (the second paper offered). In 1842-43 it was also confirmed by C.A.F. Peters at Pulkowa. It is the first published instance of the fathom-line thrown into celestial space.Bessel communicated his observations in Comptes Rendus, in a letter to Humboldt (the offered paper dated Nov. 5, 1838), in ""Monthly Notices"" in letter to J. Herschel, and in ""Astronomische Nachrichten"" Vol. 16, No 365-66 (pp. 65-96), 1838), where a more detail account was published.Ther paper ""Bestimmung der Entfernung des 61sten Stern des Schwans"" in ""Astronomische Nachrichten"" is dated at the end: Altona 1838, Dec. 13.Bessel's investigation was hailed by John Herschel when Bessel was awarded the R.A.S. gold medal ""The greatest and most glorious triumph which practical astronomy has ever witnessed"". ""For determining the parallax of 61 Cygni, Bessel selected two comparison stars of magnitude 9-10 at distances of roughly eight and twelve minutes of arc. 61 Cygni is a physical double star whose components differ in brightness by less than one magnitude. The distance of sixteen seconds of arc between the components favored the accuracy of the determination of the parallax because pointing could be carried out with two star images. After observing for eighteen months, by the fall of 1838 Bessel had enough measurements for the determination of a reliable parallax. He found that p = 0.314? with a mean error of ±:0.020?. This work was published in the Astronomische Nachrichten (1838), the first time the distance of a star became known.
