First appearance in print of the discovery of the automorphic forms which Poincaré named Fuchsian functions."One of Poincaré's first discoveries in mathematics dating to the 1880s was automorphic forms. He named them Fuchsian functions after the mathematician Lazarus Fuchs because Fuchs was known for being a good teacher and had researched on differential equations and the theory of functions. Poincaré actually developed the concept of these functions as part of his doctoral thesis. Under Poincaré's definition an automorphic function is one which is analytic in its domain and is invariant under a discrete infinite group of linear fractional transformations. Automorphic functions then generalize both trigonometric and elliptic functions." Wikipedia. unknown

First appearance of a classic paper in which Proust describes his discovery of Grape.Sugar and the identificationof this with glucose. He investigated the varieties of sugar that occur in sweet vegetable juices distinguishing three kinds and he showed that the sugar in grapes of which he announced the existence to his classes at Madrid is identical with that obtained from honey by the Russian chemist J. T. Lowitz.Proust is famous for his work on the steadiness of composition of chemical compounds."In chemistry the law of definite proportions sometimes called Proust's Law states that a chemical compound always contains exactly the same proportion of elements by mass. An equivalent statement is the law of constant composition which states that all samples of a given chemical compound have the same elemental composition. For example oxygen makes up 8/9 of the mass of any sample of pure water while hydrogen makes up the remaining 1/9 of the mass. Along with the law of multiple proportions the law of definite proportions forms the basis of stoichiometry."Wikipedia. unknown

Schmidt's paper: pp. 141-151 textillustr. A tear to inner lower corners of pp. 24-32. not affecting Schmidt's paper. Clean and fine. First printing of Schmidt's full exposition in which he describes his discovery of the radioactivity of Thorium. Schmidt and Marie Curie independently demonstrated the radioactive quality but Schmidt's demonstration took place a few months before Curie's. The discovery was announced but not described in full in a short message published in "Verhandl. d. Phys. Gesellsch. zu Berlin 1898."Schmidt made his discovery while examining "many elements and compounds" in an effeort to determine whether any of the rays that were emitted bore a resemblance to those that Henri becquerel had found emerging from uranium and uranium compounds. He located only one such element thorium and immediately conducted absorption ionization reflection refradction and poklarization studies to determine the characteristics of its rays. Having combined a misinterpretation of Becquerel's with one of his own Schmidt concluded that thorium rays most resembled Röntgen rays - a conclusion that soon required revisoln in view of the researches of Marie Curie and Ernest Rutherford."DSB XII p. 191. unknown

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. unknown

First printing of Faraday's famous letter to Gay-Lussac in which he claim to be the discoverer of electro-magnetic induction analysed the results of the Italian philosophers pointing out their errors and defending himself from what he regarded as imputations on his character. The style of this letter is unexceptionable for Faraday could not write otherwise than as a gentleman; but the letter shows that had he willed it he could have hit hard. The letter was later translated into English and published in "Philosophical Magazine" in 1840 under the title "On Magneto-electric Induction"."In 1831 seemingly out of nowhere came the discovery of electromagnetic induction and the beginning of the experimental researches in electricity which were to lead Faraday to the discovery of the laws of electrochemistry specific inductive capacity the Faraday effect and the foundations of classical field theory."

Boisbaudran's paper: pp. 322-324. First apperance of the paper in which Boisbaudran revealed his discovery of a new earth that precipitated had a unique spectrum. De Boisbaudran named it samaria after the mineral from which it was derived. The mineral samarskite is named for a Russian mining engineer and Chief of Staff - Corps of Mining Engineers Colonel Vasili Evgrafovich Samarsky-Bykhovets."Samarium was discovered by French chemist Paul Émile Lecoq de Boisbaudran in 1879. He noticed in his research that impure didymium praseodymium and neodymium with other impurities seemed to contain more than just didymium based on spectroscopic work on various rare-earth minerals. When Lecoq de Boisbaudran added ammonium hydroxide to a concentrate prepared from the mineral samarskite he observed a precipitate that formed before the didymium Weeks and Leicester 1968 p. 685.

According to P.T. Cleve "Marignac's work on the rare earths is undoubtedly the most importent in this particular department of chemistry". In 1878 marignac heated some erbium nitrate obtained from gadolinite until it decomposed. When he extracted the resulting mass with water he obtained two oxides: a red one for which he retained the name Erbia and a colorless one which he named Ytterbia."

First appearance in German of Herschel's epochal announcement of his discovery of infrared light in 1800. This was the first time that a form of light beyond visible light had been detected. The paper offered is the German translation of the main parts of Herschel's paper "An Investigation of the Powers of Prismatic Colours to Heat and Illuminate Objects"."In 1800 he tested various portions of the sun's spectrum by thermometer to see if he could find interesting differences in the amount of heat the different colors delivered. He did but in a rather unexpected way for he found that the temperature rise was highest in no color at all at a spot beyond the red end of the spectrum. He concluded that the sunlight contained invisible light beyond the red. This is now called infrared radiation. The following year Ritter was to extend the visible spectrum in the other direction."Asimov.Parkinson "Breakthroughs" 1800 P. unknown

First apperance of the papers in which Nilson describes his discovery of a new element and its properties and naming it Scandium. It was the second new element found after Mendeleev's prediction of its existence as "Eka-Boron"."Mendeléeff had predicted that another element which he called eka-boron and which he said would have an atomic weight between 40 calcium and 48 titanium would some day be revealed. 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. Nilson called it scandium in honour of his fatherland."Weeks "Discovery of the Elements" pp. 219-20.Parkinson "Breakthroughs" 1879 C. unknown
1793réf. 373234J. Dodsley London 1793. 5th Edition. Hardcover. Very Good Condition. 21 pages. This 1765 article published in The Annual Register provides a detailed account of John Harrison's groundbreaking work in solving the longitude problem at sea through the use of artificial time-keepers. Harrison an English clockmaker developed the marine chronometer a device that allowed sailors to accurately determine their longitude while at sea. His invention was crucial for safe navigation reducing the risk of ships becoming lost or wrecked due to miscalculations. The article outlines the proceedings and debates surrounding Harrison's work including his struggles with the Longitude Board which was reluctant to grant him the full 20000 prize promised under the 1714 Longitude Act. Despite proving the accuracy of his time-keepers Harrison faced political opposition and bureaucratic delays before finally receiving recognition for his achievements. Published at around the same time that Harrison's book of a similar title was published this contemporary 21 page account quotes Harrison extensively and represents the opinions and ideas regarding navigation from the perspective of the time. The whole volume extends to around 600 pages. Bound in modern but not recent brown buckram with a contrasting black leather lettering piece gilt title. Library label to the endpapers stamp on first blank and label to reverse of the title page. The first blank has a hand note stating "Given by Lt.Col. A.R. Hurst".

Some scattered brownspots. First German translation of Davy's announcement the announcement on 1 page of his discovery of the unusual anaesthetic effects of nitrous oxide which on being inhaled gave rise to a giddy intoxicated feeling. On announcing his discovery he says that he will publish a paper discribing the experiments with the gas later. This is the paper offered here also in the first German version. Both the announcement and the paper were issued in the "Annalen" the same year as they appeared in Nicholson's Journal.The gas was first synthesized by English natural philosopher and chemist Joseph Priestley in 1772 who called it phlogisticated nitrous air."Following Priestley's discovery Humphry Davy of the Pneumatic Institute in Bristol England experimented with the physiological properties of the gas such as its effects upon respiration. He even administered the gas to visitors to the institute and after watching the amusing effects on people who inhaled it coined the term 'laughing gas'! Davy even noted the anaesthetic effects of the gas: "As nitrous oxide in its extensive operation appears capable of destroying physical pain it may probably be used with advantage during surgical operations in which no great effusion of blood takes place".Wikipedia."Davy discovered the anaesthetic properties of nitrous oxide and suggested its use during surgiical operations a suggestion which was not turned to useful account until 1844."Garrison & Morton 5646 not mentioning the announcing of its discovery in 1799. unknown

First appearance of the paper in which Ramsay and Travers announced their discovery of a new element which they named "krypton" meaning hidden."Dr. William Hampson presented them Ransay & Travers with about a liter of liquid air which they used not for liquefying the argon but for obstaining sufficient skill in manipulation so that they would not risk loosing their precious fifteen liter of argon.The residue left after most of the liquid air had boliled away consisted largly of oxygen and nitrogen which Ramsay and Travers temoved with red-hot copper and magnesium. .they then examined the twenty-five cibic centimeters of residual gas and when they found it to be inerst they immediately placedit in a Pl'ucker tube connected to and induction coil and observed its spectrum. There was a bright yelælow line with a greener tint than that of the helium line and a brilliant green line that did nor coincide with any line of argon helium mercury or hydrogen. They discoverede this gas on 30 May 1898 and named it 'krypton'.they found that it belonged between bromine and rubidium in the periodic table and so great was their excitement that the younger chemist almost forgot about his examination for doctor of sciwence which had been schedules for the next day."Weeks p. 267.Parkinson "Breakthroughs" 1898 C. unknown

First appearance of the paper in which Wollaston announced his discovery of the metallic element Rhodium."Dr. Wollaston dissolved a portion of crude platinum in qgua regia and neutralized the excess acid with caustic soda. He then added salammoniac to precipitate the platinum as ammonium chloroplatinate and mercurous cyanide to precipitate the palladium as palladium cyanide. After filteringoff the precipitate he decomposed the excess mercurous cyanide inthe filtarate by adding hydrochloric acid and evaporating to dryness. When he washed the residue with alcohol everything dissolved except a beautiful dark red powder which proved to be a double chloride of sodium and a new metal which because of the rose color of its salts Dr. Wollaston named 'Rhodium'. He found that the sodium rhodium chloride could be easely reduced by heating it in a current of hydrogen and that after the sodium chloride had been washed out the rhodium remained as a metallic powder. he also succeeded in obtaining a rhodium button."Weeks: Discovery of the Elements. p. 104-05. unknown
