First printings of this series of epoch-making papers in which Janssen introduced the ""PHOTOGRAPHIC REVOLVER"" and its first successfull use leading to the ""First Film"" and hereby ""realized one of the operations necessary for cinematography""(DSB).In the first papers he conceived the idea of a device of historical interest, the photographic revolver, the technique of short exposures, which is announced here. The third paper is the epoch-making paper in which he specifically describes the ""revolver"" and its results, the ""first film"". The fourth paper is his responce to Marey's famous expriments with the ""revolver"" recording the flight of birds.""A long barreled canon-like automatic camera was invented in 1874 by an outstanding pioneer of modern astronomical photography, Jules Janssen. Janssen used the revolving plate technique and called his camera a 'pistol'. Janssen's method used the forerunner of a number of 'gun' cameras with a slowly revolving plate and shutter operated by clockwork. The photos were taken every 70 seconds along the margin of the negative and he used his pistol to record a 48 image sequence of the transit of Venus across the sun at an exposure rate of 1.5 seconds.""""In planning for the observation of the transit of Venus, which he was to observe in Japan on 9 Deembe 1874, Janssen decided to substitute for visual observation at the time of transit a series of photographs taken in rapid succession, which would permit him to measure the successive positions of the planet in relation to the solar limb. He ordered the construcion of an apparatus consisting of three circular disks with the same axis: the first, pierced by twelve slits, served as the shutter"the second contained a window" the photographic plate, which was circular, was fixed to the third. The first two disks turned with a synchronized movement, the shutter disk continuously and the other irregularly in the intervals of time in which the window was not swept by a slit. A series of separate images laid out on a circle was thus obtained on the plate. In a general manner the apparatus provided an analysis of a motion on the basis of the sequence of its elemental aspects. Here Janssen realized one of the operations necessary for cinematography, which was invented twenty years later, and which required, besides analysis, the synthesis of images."" (DSB).

Extremely rare first printing of what is arguably the world's first facsimile, namely Mads Vingaard's 1576 reproduction of the first printing of the Law of Sealand, originally printed by Ghemen in 1505 and here re-issued in exact reproduction. This wonderful print is not merely a ""line to line, word to word""-reproduction, but a facsimile making use of the same types and exact reproductions of the woodcuts. It is generally believed that ""the first facsimile in the history of the book was a manuscript of Austrian provenance - the Goldene Bulle - reproduced in 1697 by the Frankfurt law historian Heinrich Günther Thülemeyer and Johann Friedrich Fleischer"" (from ""Imagination, Almanach"" 1986-1993, Sammelheft. 1993"" 2006). The present reproduction predates that work otherwise hailed as the first ""facsimile"" in the history of the book by more than a century!Some credit Plantin in the 17th century with being the first to produce a facsimile. This is also about a century after Mats Vingaard's facsimile of the Law of Sealand. Like the laws of Sealand and The Law of Scania, The Law of Jutland"" constitutes a law book (""Rechtsbuch"" in German) in the sense of a private collection of those common laws pertaining to inheritance, ownership, marriage, measurement of land, murder, theft, vandalism, etc. that were commonly applicable in the region.The medieval Danish regional laws possess an immense importance both linguistically and legally, and the influence is evident even today, both in the development of our legal system and of our written language. At the time of their foundation, the Danish kingdom was divided into jurisdictional areas, lands, that in turn were divided into townships. Each land had a county council, which also served as a judicial court. It quite quickly became standard for the township court to be able to refer verdicts and rulings to the county/land council. In the 13th century, there were three main lands, namely Jutland, Sealand and Skåne. With time, these three lands came to rule over all townships, and thus, we find three ruling legal books from the 13th century, namely the three earliest Danish law books - Jyske Lov, the Sealandic Laws, and Skånske Lov. They were all printed for the first time in 1505 and 1505 respectively. It is not until 1683 (with ""Danske Lov"") that Denmark gets a law that covers the entire kingdom. The 1576 facsimile is scarce and Thesaurus estimates that only ab. 10 copies still exist on private hands.

First appearance of Lavoisier's FIRST PUBLISHED CHEMICAL PAPER introducing quantitative methods in chemistry, and in which he for the first time brought a hydrometer in use to measure the specific gravities of components of a chemical solutions. Lavoisier defended the originality of his approach in the following words: ""It is to the art of combination that the knowledge of the specific gravities of fluids can bring most light. This aspect of chemistry is much less advanced than we thought, we possess barely the rudiments of it."" ""This first paper, which in so many respects embodies the quantitative methods Lavoisier was to employ in his later work, had in fact been largely anticipated by others, notably by Marggraf, who had already discovered the composition of gypsum and shown that it contained water (phlegm). Yet Lavoisier’s work was more through" and his paper, his first contribution to the Academy of Sciences (read to the Academy on 25 February 1765), appeared in 1768. (The paper offered). - Lavoisier’s earliest chemical investigation, his study of gypsum, was mineralogical in character" begun in the autumn of 1764, it was intended as the first paper in a series devoted to the analysis of mineral substances. This systematic inventory was to be carried out, not by the method of J. H. Pott ""who exposed minerals to the action of fire"" but by reactions in solution, by the ""wet way."" ""I have tried to copy nature,"" Lavoisier wrote. ""Water, this almost universal solvent ""is the cheif agent she employs"" it is also the one I have adopted in my work."" Using a hydrometer, he determined with the care the solubility of different samples of gypsum (samples of selenite, or lapis specularis, some supplied by Guettard and Rouelle). He made similar measurements with calcined gypsum(plaster of paris). Analysis convinced him that this gypsum was a neutral salt, a compound of vitriolic (sulfuric) acid and a calcareous or chalky base. Not content with having shown by analysis the composition of the gypsum, Lavoisier completed his proof by a synthesis following, as he said, the way that nature had formed the gypsum. He further demonstrated that gypsum, when transformed by strong heating into plaster of Paris, gives off a vapor, which he showed to be pure water, making up about a quarter of the weight of gypsum. Conversely, when plaster of Paris is mixed with water and turns into a solid mass, it avidly combines with water. Using the expression first coined by Rouelle, he called this the ""water of crystallization."" (DSB).Partington III, pp. 378-79. -

First printing of one of the most important papers in physics, chemistry and physiology in the 19th century. The paper is the first to propose an equivalence of all forms of energy, including heat, and a conservation of total energy. Although Mayer was the first to set forth the general law of the conversation of energy (the first thermodynamical law), it was James Joule who first put the law on firm footing. ""The paper of 1842 (the paper offered) set out Mayer’s definitive view on the conservation of force and established his claim to priority"" historically the paper also provides insight into the processes through which Mayer arrived at his theory.""(DSB).""Originally trained as a physician, mayer did not enjoy medical practice. About 1840 he began to be interested in physics and he entered thhe field of research, ... In 1842 he not only presented a figure for the mechanical equivalent of heat, but he also clearly presented his belief in the conversation of energy. He had some difficulty getting his paper on the subject published but Liebig finally accepted for the importent journal he edited. Though Mayer was five years ahead of Joule his paper aroused no interest, and in the end it was Joule, with his imposing experimental background. who received credit for working out the mechanical equivalent of heat. And it was Helmholtz who recieved credit for announcing the law of conservation of energy because he announced it so much more systematically. Yet Mayer went further than either of the other two, for he included living phenomena in the realm of energy conservation (a daring step in a decade when vitalism, with its view that the laws of inanimate nature did not apply to living systems, was still a considerable force). Mayer argued that solar energy was the ultimate source of all energy on earth, both living and non-living. He further suggested that solar energy was derived from the slow contraction of the sun, or by the fall of meteors into the sun, in either case kinetic energy being converted to radiant energy.""(Asimov)""After 1860, Mayer was finally given the recognition he deserved. Many of his articles were translated into English, and such well-known scientists as Rydolph Clausius in Germany and John Tyndall in England began to champion Mayer as the founder of the law of the conservation of energy.""(Alan Lightman ""Great Ideas in Physics"", p. 8).Parkinson ""Breakthroughs"" 1842 P. - Magee ""A Source Book in Physics"", p. 196 ff. - Dibner: 157 (listing the offprint with a different title) - PMM: 330 (offprint-version). - Garrison & Morton: 606.

Three first editions by Euler. Euler's goal in the first paper is to show that certain phenomena that resulted from the eclipse of July 25, 1748 are evidence that the moon has an atmosphere that is almost 200 times less dense than that of the earth. (The phenomena Euler observed are optical effects of light passing close to a sharp edge, and not the refraction of a lunar atmosphere).The other papers on the physics of rigid bodies are groundbreaking as Euler here set forth what is known as ""Euler's dynamical equations of the motion of the mass-center of any solid"", and thus STATING FOR THE FIRST TIME THE LAW OF DRY FRICTION, mathematically. Euler explains his experiments with the inclined plane and discovers the DIFFERENCE BETWEEN KINETIC AND STATIC FRICTION.""Leonhard Euler occupied himself with the mathematical point of view of friction as well as the experimental. He introduced the differentiation between static frictional forces and kinetic frictional forces, and solved the problem of rope friction, probably the first contact problem to be analytically solved in history. (1750, the papers offered). He was the first to lay the foundations of the mathematically way of dealing with the law of dry friction and in this way promoted further development. We have to thank for the symbol as the coefficient of friction. Euler worked with the idea that friction originates from the interlocation, between small triangular irregularities.This understanding survived, in different variations,for a hundred years and is also used today as the ""Tomlinson Model"" in connection with friction on atomic scale.""(L.

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. Bessel’s value for the parallax shows excellent agreement with the results obtained by extensive modern photographical parallax determinations,...""

"EINSTEIN, ALBERT. - THE FIRST EXPLICIT STATEMENT OF THE ENERGY-MASS EQUATION !!

Leibzig, Johann Ambrosius Barth, 1907. 8vo. Contemp. hcalf. Spine gilt. Title-and tomelabels with gilt lettering. Slightly rubbed. In ""Annalen der Physik"", Vierte Folge, Band 23. VIII,1000 pp. a. 4 plates. (The entire volume offered). Einstein's paper: pp.371-384. A small stamp on titlepage (Gmelin.Institut.). Internally clean and fine.
First edition of the first explicit statement of Einstein's energy-mass equation E=mc2.Nearly all descriptions of Einstein's scientific work state that the mass-energy equivalence E=mc2 was first formulated in Einstein's 1907 review paper 'Über das Relativitätsprinzip und die aus demselben gezogenen.' published in 'Jahrbuch der Radioaktivität und Elektronik' (see Weil no. 21 and Dictionary of Scientific Biography, vol. 4 pp.323 for examples). However, in his paper 'Über die von Relativitätsprincip geforderte Trägheit der Energie' [the offered paper] which predates the former mentioned by six months, Einstein gave a clear statement of the mass-energy equivalence E=mc2. See Lanczos: The Einstein Decade, pp.149-150 and 153 as well as Volume 2 of 'The Collected Papers of Albert Einstein' pp. 428.Einstein's first paper regarding the relation E=mc2 is his fourth 1905 paper, 'Ist die Trägheit eines Körpers von seinem Energieinhalt abhängig?'. In this short paper Einstein showed that a body releasing the energy E in the form of radiation will have its mass decreased by E/c2, and concluded that the mass of a body is a measure of its energy content, e.g., that all energy has mass. The next time Einstein returns to the subject is in his 1906 paper 'Das Prinzip von der Erhaltung der Schwerpunkts Bewegung und die Trägheit der Energie.'. Here Einstein concluded that one must either ascribe the inertial mass E/c2 to any form of energy E or else give up the fundamental law mechanics regarding conservation of the motion of the center of gravity. Then finally in the 1907 paper 'Über die von Relativitätsprincip geforderte Trägheit der Energie.' [the offered paper] Einstein makes the decisive step of assuming that all mass has energy. On page 382 Einstein considers the total energy of a moving mass point as the sum of its kinetic energy and its rest energy. In classical mechanics it is most convenient to set the second term to zero but in relativistic mechanics one obtains the simplest expression by setting the rest energy equal to mc2. Einstein then continues to show that this stipulation cannot lead to a contradiction in any relativistic argument. In a footnote on page 382 Einstein states for the first time the equation E=mc2 and mentions that this equation is the expression of the principle of the equivalence of mass and energy - see Volume 2 of 'The Collected Papers of Albert Einstein' pp. 428.The volume contains another paper by Einstein ""Bemerkungen zu der Notiz von Hrn.

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. Bessel’s value for the parallax shows excellent agreement with the results obtained by extensive modern photographical parallax determinations,...""

First edition of the first explicit statement of Einstein's energy-mass equation E=mc2.Nearly all descriptions of Einstein's scientific work state that the mass-energy equivalence E=mc2 was first formulated in Einstein's 1907 review paper 'Über das Relativitätsprinzip und die aus demselben gezogenen.' published in 'Jahrbuch der Radioaktivität und Elektronik' (see Weil no. 21 and Dictionary of Scientific Biography, vol. 4 pp.323 for examples). However, in his paper 'Über die von Relativitätsprincip geforderte Trägheit der Energie' [the offered paper] which predates the former mentioned by six months, Einstein gave a clear statement of the mass-energy equivalence E=mc2. See Lanczos: The Einstein Decade, pp.149-150 and 153 as well as Volume 2 of 'The Collected Papers of Albert Einstein' pp. 428.Einstein's first paper regarding the relation E=mc2 is his fourth 1905 paper, 'Ist die Trägheit eines Körpers von seinem Energieinhalt abhängig?'. In this short paper Einstein showed that a body releasing the energy E in the form of radiation will have its mass decreased by E/c2, and concluded that the mass of a body is a measure of its energy content, e.g., that all energy has mass. The next time Einstein returns to the subject is in his 1906 paper 'Das Prinzip von der Erhaltung der Schwerpunkts Bewegung und die Trägheit der Energie.'. Here Einstein concluded that one must either ascribe the inertial mass E/c2 to any form of energy E or else give up the fundamental law mechanics regarding conservation of the motion of the center of gravity.

First edition of this important first systematical treatment of the theory of complex numbers and at the same time, the first work to add vectors in three-dimensional space.""Wessel’s fame as a mathematician is based entirely on one paper, written in Danish and published in the Mémoires of the Royal Danish Academy, that established his priority in publication of the geometric representation of complex numbers. John Wallis had given a geometric representation of the complex roots of quadratic equations in 1685"" Gauss had had the idea as early as 1799 but did not explicitly publish it until 1831. Robert Argand’s independent publication in 1806 must be credited as the source of this concept in modern mathematics because Wessel’s work remained essentially unknown until 1895, when its significance was pointed out by Christian Juel. The title of Wessel’s treatise calls it an ""attempt"" to give an analytic representation of both distance and direction that could be used to solve plane and spherical polygons. The connection of this goal with Wessel’s work as a surveyor and cartographer is obvious. The statement of the problem also suggests that Wessel should be credited with an early formulation of vector addition. In fact, Michael J. Crowe, in A History of Vector Analysis (University of Notre Dame Press, 1967), defines the first period in that history as that of a search for hypercomplex numbers to be used in space analysis and dates it from the time of Wessel, whom he calls the first to add vectors in three-dimensional space.""

First printing of the famous paper in which Draper relates how he was able to made the first photographic portrait on a daguerreotype plate, giving an ennormously long exposure. The subject of the portrait, Draper's assistant, powdered his face with flour and sat in front of the camera for a half hour facing the sunlight.Draper stated that it is possible to make portraits in full sunlight, using mirrors as light reflectors. ""But in the reflected sunshine, the eye cannot support the effulgence of the rays. It is therefore necessary to pass them through some blue medium, which shall abstract from them their heat and take away their offensive brilliancy. Ihave used for this purpose blue glass, and also ammoniaco-sulphate of copper, contained in a large trough of plate glass, the interstice being about an inch thick."" (p. 217 in the paper offerd).""Draper first achieved wide celebrity for his pioneering work in photography. As early as 1837, while still in Virginia, he had followed the example of Wedgwood and Davy in making temporary copies of objects by the action of light on sensitized surfaces. When the details of Daguerre’s process for fixing camera images were published in various New York newspapers on 20 September 1839, Draper was ready for the greatest remaining challenge, to take a photographic portrait. A New York mechanic, Alexander S. Wolcott, apparently won the race by 7 October. But if Draper knew of this, he persisted in his own experiments and succeeded in taking a portrait not later than December 1839. His communication to the Philosophical Magazine, dated 31 March 1840, was the first report received in Europe of any photographer’s success in portraiture. The superb likeness of his sister Dorothy Catharine, taken not later than July 1840, with an exposure of sixty-five seconds, seems to be the oldest surviving photographic portrait.""(DSB).The volume contains also Michael Faraday's importent letter to Gay-Lussac on induction in the first English version.
