"Henry independently discovered electro-magnetic induction and in this paper announced his discovery of electric self-induction one of the prime properies of an electro-magnetic circuit. Henry was an eminent experimenter but was casual in publishing his findings with resulting lack of recognition of his contributions."Bern Dibner.Dibner "Heralds of Sciece" No.63.It was also printed the same year in "Transactions of the American Philosophical Society New Series Vol. 5". The paper was later printed in "Philosophical Magazine" 1840."The direction of Henry’s thought became somewhat apparent in his 1835 paper refers to the papers reading before the American Phil. Soc. febr. 6th 1835 on the action of a spiral conductor in increasing the intensity of galvanic currents. The paper started out as an affirmation of Henry’s priority in the discovery of self-induction. He then combined induction proper using Faraday’s findings and his own with selfinduction to show how these produce a pattern of repulsions yielding an increased effect in spirals. He specifically linked these “magneto-electrical” results to the principles of static induction developed by Cavendish and Poisson. This explanation was then applied to Savary’s report of changes of polarity when magnetic needles were placed at varying distances from a wire in which a current was being transmitted "Mémoire sur l’aimantation" in Annales de chimie et de physique 34 1827. That is currents appeared periodically in the air surrounding a current-bearing straight wire as a result of the actions of induction and self-induction." DSB.Wheeler Gift: 2724-2725a. unknown

First apperance of the paper relating Marignac's discovery of the rare earth Ytterbium Ytterbia."He began his study of the rare earths in 1840 when he was barely twenty-three years old. 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 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."

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

Skew Variations in Homogenous Materials" etc.After having made several measuring of the densities of gases "Rayleigh came across a curious puzzle. With oxygen he always obtained the same density regardless of how the oxygen might be produced whether from one particular compound from a second compound or from the air. The situation was different with nitrogen. The nitrogen he obtained from air constantly showed a slightly higher density than the nitrogen he obtained from any of various compounds. Rayleigh could think of several ways in which the nitrogen obtained from air might be contaminated but none of the possibilities checked out experimentally. He was so frustrated that he went so far as to write to the journal "Nature" asking for suggestions. Ramsay a brilliant Scottish chemist asked permission to tackle the problem and received it. The upshot was that a new gas somewhat denser that nitrogen was discovered to exist in the atmosphere. It was named argon and it was the first of a series of rare gases of unusual properties whose existence had never been suspected."Asimow.Dibner Heralds of Science No. 50 - Neville Historical Chemical Library vol.

First appearance in German of this monumental paper in atomic theory and kinematics as it was the first evidence for atomism that was an observation rather than a deduction from abstract principles."In 1827 as he was viewing a suspension of pollen in Water under the microscope he noted that the individual grains were moving about irregularly. This he thought was the result of the life hidden within the pollen grains. However when he studied dye particles indubitably nin-livin suspended in water he found the same erratic motion. This has been called "Brownian motion" ever since and Brown could merely report on the observation. He had no explanation for it. Nor had anyone else until the development of the kinetic theory of gases by men such as Maxwell a generation later. It seemed plain. after Maxwell and especially after the work of Einstein and Perrin a half century after Maxwell that the Brownian Motion was actually a visible effect of the fact that water was composed of particles.

First appearance of this milestone paper in chemistry physics and astronomy announcing the discovery of the helium lines in the spectrum of the sun. It was Lockyer in the same year that named it 'helium' for Helios the Greek God of the Sun. Helium was not discovered on the earth before 1895 by William Ramsay and it was Crookes who established its identity with the helium Janssen and Lockyer observed in the spectrum of the sun."He Janssen met immortality by travelling to India in 1868 to study the total eclipse. It was then that he observed the helium line and forwarded the spectral data to ockyer. He also noted the size of the solar prominences. The day after the eclipse he attempted to take their spectra again and succeeded despite the absence of the obscuring moon. he then announced jubilantly that it was the day after the eclipse that was the real eclipse day for him. Lockyer also reported this method of studying prominences without an eclipse.Like Lockyer he lived to see his observation of the helium line vindicated by Ramsay's discovery of that element on earth."Asimov."This the discovery of helium lines in the sun by Lockyer was announced on the same day by the French astronomer Janssen who was in India observing a total eclipse. As a result the French government some ten years later struck a medallion showing the heads of both scientists.By that time the two men had made a much more dramatic discovery at the same time this time in cooperation. Janssen studying the spectrum ofthe sun during the eclipse had noted a fine line he did not recognize. he send a report on this to Lockyer an acknowledges expert on solar spectra. Lockyer compared the reported position of the line with lines of known elements concluding that it must belong to a yeat unknown element possibly not even existing on the earth. He named the element from the Greek word for the sun."Asimov.Parkinson "Breakthroughs" 1868 A. - The volume contains other notable papers by Dumas Berthelot et al. hardcover

First apperance of Villard's two papers in which he announced and described the discovery of a new type of radiation more powerfull and penetrating than alpha-and beta rays. The new type of rays was named by Rutherford as gammarays."His Villardexperiments in radioactivity led to the unexpected discovery of gamma rays in 1900. Villard recognized them as being different from x rays because the gamma rays had a much greater penetrating depth. He had discovered they were emitted from radioactive substances and were not affected by electric or magnetic fields. These came to be called gamma rays by another scientist Ernest Rutherford. It wasn't until 1914 that Rutherford showed that they were a form of electromagnetic EM like light only with a much shorter wavelength than x rays. Now we know that gamma rays are a form of EM radiation similar to x rays. Gamma rays tend to have a higher energy and a shorter wavelength than x rays do. However the dividing line between these two forms of radiation is not clearly defined. Scientists typically apply the term gamma ray to EM radiation with energies above several hundred thousand electron volts."

THESE PAPERS ARE SOME OF THE GREAT CLASSICS OF CHEMISTRY AND PHYSICS."Faraday demonstrated this theory involving the lines of force.by inserting a magnet into a coil of wire attached to a galvanometer. While the magnet was being inserted or removd current flowed through the wire. If the magnet was held stationary and the coil moved over it one way or the other there was current in the wire. In either case the magnetic lines of force about the magnet were cut by the wire.If the magnet and coil were both held motionless whether the magnet was within the coil or not there was no current.Faraday hd thus discovered electricalinduction.It was to lead to great things but this was not apparent."Asimov."Although his discovery of the electric motor and the dynamo was almost entirely identical to his theoretical discoveries it laid the foundation of the modern electrical industry - electric light and power teælephony wireless telegraphy televison etc. - by providing for the production of continous mechanical motion from an electrical source and vice versa."

First appearance of the six landmark papers in which Becquerel documents his discovery of Radio-activity PROMPTING THE NUCLEAR AGE.Becquerel was an expert in fluorescence and phosphorescence continuing the work of his father and grandfather. Follwing the discovery of X-rays by Röntgen Bexquerel investigated fluorescent materials to see if they also emitted X-rays. He exposed a fluorescent uranium salt pechblende to light and then placed it on a wrapped photographic plate.He found that a faint image was left on the plate which he believed was due to the pichblende emitting the light it had absorbed as a more penetrating radiation. However by chace he left a sample that had not been exposed to light on top of a photographic plate in a drawer. he noticed that the photographic plate also had a a faint image of the pechblende. After several chemical tests he concluded that these "Becquerel rays" were a property of atoms. He had by chace discovered radio-activity and prompted thee beginning of the nuclear age. He shared the Nobel Prize for Physics in 1903 with Marie and Pierre Curie. The "Becquerel Rays" were later discovered to be a composite of three forms of emanation distinguished by Rutherford as alpha beta and gamma rays.Dibner: 163 the later Mémoire from 1903 - PMM: 393 1903- Mémoire - Garrison & Morton: 2001 only the first paper. - Magie "A Sourve Book in Physics" p. 610 ff. - Norman:157. hardcover

First on the nature of the metals of the fixed alkalis. Second on the nature of Hydrogen and composition of ammonia. Thirdly on the metals of the earth; and Fourthly he makes a comparison between the antiphlogistic doctrine and a modified phlogistic hypothesis."Abstract. He further gives arguments for considering potassium and sodium which he discovered in 1808 as a element."Humphry Davy was one of the most brilliant chemists of the early nineteenth century. His early study of nitrous oxide brought him his first reputation but his later and most importent investigations were devoted to electrochemistry. Following Galvani's experiments and the discovery of the voltaic pile interest in galvanic electricity had become widespread. The first electrolysis by means of the pile was carried out in 1800 by Nicholson and Carisle who obtained oxygen and hydrogen from water.

Following this up Stromeyer found himself interested in zinc carbonate which turned yellow on strong heating as though it contained iron as an impurity yet it contained no iron. He traced the yellow to an oxide not of zinc but of a hitherto unknown metal rather like it chemically. He named it cadmium for a zinc ore in which it is usually found accompanying the zinc."Asimov.Weeks "Discovery of the Elements" pp. 135-39. unknown

In reality it was found by del Rio in 1801 he named it Erythronium but upon further study he decided that he was mistaken as his further studies showed that it was made up of a basic lead chromate. unknown

Wurtz's paper: pp. 223-226. First appearance of the announcement of Wurtz's outstanding discovery of Liebig’s prediction that there might be organic compounds analogous to ammonia and derivable from it by the replacement of hydrogen - the amines. The entire memoir was not published in full until 1855 in 'Annales de Chimie et de Physique'.Wurtz is most noted for his investigation of glycols and for his discovery of the amines. The latter discovery in 1849 the paper offered was very significant at the time for ot suggested the possibility of a new type the ammonia type which helped to explain the behaviour of nitrogenous compounds.

First apperance of the papers in which Lecoc de Boisbaudran described how he separated Holmium into two kinds of earths and naming them."He accomplished this by fractional prepicitation first with ammonium hydroxide and then with a saturated solution of potassium sulfate and found that the constituents of pure holmium solutions precipitate in the folloeing order: terbium dysprosium holmium and erbium. Lecog de Boisbaudran never had an abundant supply of raw materials for his remarkable researches on the rare earths and he once confided to professor Urbain that most of his fractionations had been carried on on the marble slab of his fireplace."Weeks "Discovery of the Eelements".Parkinson "Breakthroughs" 1886 C. unknown

Matteucci's paper: pp. 540-41. First appearance of a main paper in the history of electro-physiology."The discovery by Volta of means for producing galvanic currents led to the construction of a galvanometer for measuring currents and later to its refinement. In 1841 Matteucci presented. a paper which showed that a galvanometer indicates a curring flowing whenh it is connected from the surface of a muscle to a wound in the muscle a current that was later called the "current of injury" and also the "current of rest" since it flowed without observable muscular contraction. Johannes Müller showed tis paper to his brilliant pupil du Bois-reymond. Du Bois interest was caught at once. He published his first paper on "thierische Electricität" in 1843 and his two-volumes on the subject - soon to become the classic - in 1848-49."Boring "History of Experimental Psychology" p. 40. unknown

Entire issue offered with printed wrappers. Wöhler a. Liebig's papers: pp. 185-209 a. pp. 209-217. First appearance of this classic paper in organic chemistry in which Wöhler and Liebig showed how Amygdalin could be decomposed by a vegetable emulsion the first example of a glycoside. The papers were issued at the same time in "Annalen der Physik und Chemie"."The conclusions which you have drawn from the investigation of bitter-almond oil" wrote Berzelius to Liebig and Wöhler "are certainly the most importent which have so far been reached in the domain of vegetable chemistry and give promise of shedding an unexpected light over this part of the science.The facts which you have set forth inspire such reflections that they may be regarded as the dawn of a new day in vegetable chemistry."Berzelius-Wöhler Briefwechsel."During the years that Liebig was preoccupied with the ether theory and with organic acids he also carried out two importent investigations with Wöhler. In october 1836 Wöhler wrote that he had discovered a way to transform amygdalin to oil of bitter almonds and hydrocyanid acis by distilling it with manganese and sulfuric acid and he invited Liebig to join in pursuing the topic. Two days later he made a more remarkable discovery. It had occurred to him that perhaps thetransformation of amygdalin could be effected by the albumin in the almonds in a manner similar to the action of yeast in sugar.Wöhler suspected that the decomposition was an example of what Berzelius had recently defined as catalysis. Liebig and Wöhler then divided up the detailed examination of the properties and composition of amygdalin. They precipitated from the emulsion of almonds a substance which when dissolved retain its action. They named the active substance "emulsion". Its effectiveness in very small quantities confirmed that it acted like yeast."DSB VIII p. 342. unknown
