Donné's paper: pp. 366-368. First printing of the paper announcing the discovery of blood-platelets THE THIRD CORPUSCLES OF THE BLOOD. Platelets or thrombocytes or yellow blood cells are very small irregularly shaped clear cell fragments i.e. cells that do not have a nucleus containing DNA 2-3 µm in diameter which derive from fragmentation of precursor megakaryocytes. The average lifespan of a platelet is normally just 5 to 9 days. Platelets are a natural source of growth factors. They circulate in the blood of mammals and are involved in hemostasis leading to the formation of blood clots. Platelets release thread-like fibers to form these clots.Garrison & Morton 864. unknown

Janssen's paper pp. 367-376. First printing of the paper in which Janssen announced the discovery of a new element. On August 18 1868 Janssen managed to do just that. He became the first person to observe helium an element never before seen on Earth in the solar spectrum. At the time though Janssen didn’t know what he’d seen"just that it was something new""Helium the second most abundant element in the universe was discovered on the sun before it was found on the earth. Pierre-Jules-César Janssen a French astronomer noticed a yellow line in the sun's spectrum while studying a total solar eclipse in 1868. Sir Norman Lockyer an English astronomer realized that this line with a wavelength of 587.49 nanometers could not be produced by any element known at the time. It was hypothesized that a new element on the sun was responsible for this mysterious yellow emission. This unknown element was named helium by Lockyer." unknown

The scarce first edition of the work in which Steenstrup describes his discovery of the principle of 'ALTERNATION OF GENERATIONS'' sexual and asexual in plants and animals. "Steenstrup showed that certain animals produce offspring which never resemble them but which on the other hand bring forth progeny which return in form and nature to their grandparents or more distant ancestors." Garrison & Morton No 217. A German translation was published the same year and an English in 1845. Norman 2009 German translation. "The second major publication - the first dealing with geology - of 1842 was "Om Forplantning og Udvikling gjennem vexlende Generationsrækker." the work offered Steenstrup's comprehensive presentation of the form of reproduction that he called 'alternation of generations' that is the alternation of asexual and sexual reproduction or metagenesis. This phenomenon had previously been described by Chamisso but Steenstrup included a greater number of observations based on a significantly wider range of subjects and provided an importent chapter on its meaning. Steenstrup's growing reputation won him an appointment as professor of zoology at the University of Copenhagen where he tought from 1846 until 1885."DSB XII p. 9. unknown

Entire issue offered with titlepage to volume 16. Berzelius's paper: pp. 387-415. Clean and fine. 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 this importent paper in the history of chemistry Lord Rayleigh's most famous discovery announcing the discovery of this new gas the first finding of one of the rare gases inert gases having unusual properties and forming a distinct group in the periodic table and all with zero valency."The original paper in the "Philosophical Transactions" will undoubtly rank as a classic the investigation having been a particularly brilliant ine." Ernst von Meyer in History of Chemistry. For this discovery Lord Rayleigh and W. Ramsay received the Nobel Prize 1904.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.

The entire issue offered. Henry's paper: pp. 282-312. First German version of Henry's description of his discovery of self-induction. He missed the credit for the discovery of induction to Faraday but he had done the key experiment ahead of Faraday but Faraday was the first to publish. But he is credited for the discovery of self-induction 1832 and Faraday discovered it independently two years later 1834."In Henry's paper however he explained thet the electric current in a coil can induce another current not only in another coil but in itself. The actual current observed in the coil is then the combination of the original current and the induced current. This is called self induction."Isac Asimov.The issue contains further notable papers Michael Faraday's "Vierzehnte Reihe von Experimental-Untersuchungen über Elektricität" § 2o-22. Nos 1667-1748. Pp. 249-281. First German version. In this paper FARADAYamplifies his theory of electrostatic induction by making further use of the analogy with the induction of magnetism. Whittaker describes the paper as having "THE FUNDAMENTAL EQUATION OF ELECTROSTATICS" as modified in order to take into account the effect of the specific inductive capacity."Whittaker I pp.187-89. unknown

Entire issue offered. Ørsted's paper: pp. 417-25. A few scattered brownspots. First French translation and the first translation of Oersted's epoch-making announcement in his Latin pamphlet "Extperimenta circa effectum conflictus electrici in acun magneticam. Hafniæ 1820" privately printed in a very small number and only distributed to colleques in Europe. This discovery and confirmation of the connection between 2 forces electricity and magnetism must be considered one of the happiest events in the history of science both with regard to scientific and practical results. - "From the moment that Ørsted's discovery became known it created an enormous sensation. The results communicated were so astounding that they were received with a certain distrust but they were stated with such accuracy that it could hardly be permitted to entertain any doubts. In the course of a short time the treatise was translated into all the chief languages." Kirstine Meyer. - Dibner:61 - PMM: 282 - Horblitt: 3 b. - Sparrow: 152. unknown

Edited by Richard Taylor." Vol. I. Pp. 540-547. Henry's milestone paper announcing his discovery of electrical self-induction. "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
