Textillustrations, depicting Wilson's famous apparatus First printing of this groundbreaking paper in which Wilson describes the invention which made it possible to view the track of a single atomic projectile or electron. The invenvention of the "Dust-Chamber" made it possible for J.J. Thomson in 1897 to calculate the charge of the electron, and thereby finding its mass, since the ratio between the two was known. In most cases it was found that the track of the particle is a straight, or nearly straight line."C.T.R. Wilson had been developing his cloud-chamber, which was to provide the most powerfull of all methods of investigation in atomic physics. In moist air, if a certain degree of supersaturation is exceeded this can be secured by a sudden expansion of the air) condensation takes place on dust-nuclei, when any are present: if by preliminary operations condensation is made to take place on the dust-nuclei, and the resulting droplets are allowed to settle, the air in the chamber is thereby freed from dust. If now X-rays or radiation from a radioactive substance are passed into the chamber, and if the degree of supersaturation is sufficient, condensation again takes place: this is due to the production of ions by the radiation. Thus the tracks of ionising radiations can be made visible by the sudden expansion of a moist gas, each ion becoming the centre of a visible globule of water. Wilson showed that the ions produced by uranium radiation were identical with those produced by X-rays." (Whittaker in "A History of the Theories of Aether & Electricity" II:p.4).

First German translations of these fundamental papers in which Dalton formulated his gas-and pressure laws, such as "The Law of Partial Pressures" , "The Charles Law" or The Charles-Gay-Lussac Law" (this law arrived at almost simustaneously with Gay-Lussac).These papers were read and published in the memoires from the "Manchester Literary and Philosophical Society" in 1801 and 1802 in 4 parts, the German translation, the item offered, is divided in 5 parts, probably incorporating the paper from Nicholson's Journal from 1801. The publication of these papers gave him at once international reputation they tried to explain why the gases of the atmosphere remain mixed instead of segregating with the heaviest element at the bottom, it states that the maximum density of a vapour in contact with its liquid remains the same whether other gases be present or not and the vies that the particles of everykind of elastic fluid are elastic only with regard to their own kind. and that the otal pressure of the atmosphere equals the sum of the pressures exerted by the individual gases, each of which excerts its pressure independently of the others. This was the first step toward his atomic theory of in chemistry. - He also showed that the quantity of water evaporated in a given time to be stricktly proportional to the force of aqueous vapour at the same temperature, and last, announcing the law that all elastic fluids expands the same quantity by heat, "The Charle's Law or Charles-Gay-Lussac Law".

In the first paper Euler analyzes the forces that act on a slice of air that is in a disturbed state at y but was initially at x. The analysis is customary in the modern elementary works. In the second paper Euler gets a result that is equivalent to the general formula ofinversion for partial differentiations, noting in addition that cylindrical and spherical waves also follow it."Euler, Lagrange, and others worked on the propagation of sound in air. Euler wrote on the subject of sound frequently from the time he was twenty years old (1727) and established this field as a branch of mathematical physics...Three fine and definitive papers were read to the Berlin Academy in 1759 (the papers offered here).

First edition of these 3 groundbreaking papers with the first appearance in print of THE LAW OF THE CONSTANCY OF ATOMIC HEAT, i.e. the specific heat multiplied by the atomic weight. The insight had far reaching implications as it showed a new way to Dalton's atomic theory."In 1815 Dulong's famous collaboration with the mathematical physicist Alexis Therese Petit began; it produced three importent memoirs on heat." (the papers offered here). The 2 first was awarded the price of the Academy in 1818 and was leading up to the last paper in which they formulted the "Law of the Constancy of product of atomic weight and specific heat""They (Dulang and Petit) were concerned with the specific heats of elements; but if these elements really existed as atoms, it seemed possible that there might be a connection between trhe weight of the atom and the amount of heat aquired to raise the temperature of a given weight of that element by a certain amount." (DSB). - "One of his (Dulong) most importent researches was made in collaboration with Alexis Thérese Petit (1791-1820), with whom he announced the law that the product of atomic weight and specific heat is constant (1819). It rendered a distinct service in fixing atomic weights, especially when these were in question, and enabled Berzelius and later Cannizzaro to arrive at correct atomic weights and the correct number of atoms in molecules."

The paper offered is the first edition, first printing of the text from Minkowski's famous address held at the 80th meeting of the Gesellschaft Deutscher Naturforscher und Ärzte, in Köln the 21st September 1908. There exists three other printings of this address from the same year:1. Physikalische Zeitschrift, volume 10, number 3 (1. February, 1909.), pp.104-111; 2. Jahresbericht der Deutschen Mathematiker-Vereinigung, volume 18, number 2 (issued monthly - so February), pp.75-88;3. (Seperate edition by Teubner)."The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strenght. They are radical. Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a inf of union of the two will preserve an independent reality" He ended as follows: 'the validitywothout exception of the world postulate (i.e., relativity postulates), I like to think, is the thrue nucleus of an electromagnetic image of the world, which, discovered by Lorentz, and further developed by Einstein, now lies open in the full light of the day'"(Pais in "Subtle is the Lord", p. 152).Here (in the paper offered) "he introduced the notion that made possible the expansion of the Relativity Theory of Einstein from its specific to its general form. The technical description of Minkowski's hypothesis is the four-dimensional Space-time continuum....Minkowski's space-time hypothesis was in effect a restatement of Einstein's basic principle in a form that greatly enchanced its plausability and also introduced importent new developments. Hitherto natural phenomena had been thought to occur in a space of three dimensions and to flow uniformly through time. Minkowski maintained that the separation of space and time is a false conception; thet time is itself a dimension, comparable to lenght, breadth and height: and that therefore the true conception of reality was constituted by a space-time continuum possessing these four dimensions. This strongly reinforced Einstein's objections to absolute concepts and supported his view of the relativity of events in nature."

Internally clean and fine, and wide-margined. Third and last 16th century Latin edition of Saxo's "History of Denmark", edited by Philip Loncier, rector of the Frankfurt Gymnasium.Saxo Grammaticus (ab. 1150-1220) was probably a secular clerk or secretary to Absalon, Archbishop of Lund, the great Danish churchman, statesman and warrior. Saxo is remembered today as the author of the first full history of Denmark, in which he modeled himself on the classical authors (e.g. Virgil, Plato, Cicero) in order to glorify his fatherland. The work dates from the end of the 12th century and was edited by Christiern Pedersen, a Canon of Lund, and printed by Jodocus Badius Ascendius in Paris in 1514 (the editio princeps) with 16th century re-issues following in 1534 (Basel) and 1576 (the present). Only with the first printing of this seminal work did the work become known throughout academic circles. The work soon received international fame and is to this day renowned as not only being immensely important historically, but also being extremely well written (Saxo is praised by Erasmus, for instance, for possessing great power of eloquence). The work consists of sixteen books that cover the time from the founders of the Danish people (Dan I of Denmark) till Saxo's own time, ending around 1185 (with the submission of Pomerania), when the last part is supposedly written. The work thus covers the entire history of Denmark until Saxo's own time, seen under a somewhat glorified perspective, from heathen times with tales of Odin and the gods of Valhalla to the times of Absalon, who probably directly influenced the sections on the history of his own time, working closely with Saxo himself. Apart from that, the work contains the first known written narration of the legend of Hamlet (Amleth, the son who took revenge for his murdered father). It is most likely this narrative of Saxo's, which he based on an oral tale, that forms the basis for Shakespeare's "Hamlet", which takes place in Helsinore in Denmark. There is fairly certain evidence that Shakespeare knew Saxo's work on the History of Denmark and thus, from that, the legend of Amleth.The editio princeps was printed in Paris in 1514, the second edition being printed in Basel in 1534.LN 1450Thesaurus 190.

[Stockholm], 1745. 8vo. Extracted from "Kgl. Svenska Vetenskapsakademiens handlingar", 1745, 6. In recent stiff paper wrappers. Uncut, nice and clean. Pp. 116-17. [Pp. 115-18 present]. Seminal first printing of the first actual description of (speech order) aphasia.Linné here describes the case of a patient of his, who suffered from gout, which in the fall of 1742 went to his brain instead of his feet. For the first time, we here find an actual description of speech order aphasia, as Linné states "... he seemed to be raving... he was sort of speaking his own language, having his own names for all words... He had forgotten all the nouns, so that he did not remember one single one; not even the name of his children, his wife or himself, let alone anybody else. And what was even more strange, if you mentioned something he wanted to say, he said yes; but if you asked him to repeat it he replied "can nothing", when he saw someone's name, he knew who it was, and when he wanted to mention one of his colleagues, he pointed to the Catalogum Lectionum, where the name was mentioned." Linné's conclusion is: "Thus, he had lost two things; first the memory of all nouns, and second, the ability to name the nouns." [Own translation from Swedish]. This condition lasted till about Christmas, and the following year, the patient died.The present work is highly interesting in more than one respect. Fist it is of great importance as being the first actual description of speech aphasia, and the first description of aphasia to be given accurately by a physician (vague descriptions of something that might be similar had occurred in blurred forms in the 16th century, and it may therefore be considered not quite accurate, when Garrison and Morton state of the present treatise "Aphasia first described"). The year before Linné's treatise, the great Enlightenment philosopher Biambattista Vico had reported the first known case of a verb production aphasia, and when Linné the following year describes the first reported case of impaired noun production, we actually here, within one year, establish an identification and documentation of both verbal- and noun- dissociation of lexical category retrieval, and thus the actual foundation of aphasia-research."Anomia, especially word-finding difficulty affecting nouns and other substantive words, was well documented before epochal observations of Paul Broca ushered in the modern era of aphasiology. A man who lost the "memory of all substantives" as well as the "power to name the substantives" was reported in 1745 by Linnaeus, the Swedish botany taxonomist." (Kirshner, "Handbook of Neurological Speech and Language Disorders, p. 166)."SPEECH DISORDER Aphasia was described by Carl Linnaeus (1707-1778) in 1745 and the site of the lesion in the brain causing it was suggested by Jean Baptiste Boulland in 1825." (Sebastian, "A Dictionary of the History of Medicine").Apart from those two aspects of the present article, it also raises highly important questions within the fields of psychology, philosophy, linguistics, and logic. Aphasia raises essential questions about the relation between brain and language, a theme which has occupied almost all modern analytical philosophers and logicians (e.g. Wittgenstein etc.), and it thus plays an important role in the area of research of these disciplines.Garrison and Morton: 4616; Hulth: p. 44.

(Paris), Minuet, 1967. 8vo. Original wrappers. A very nice and clean copy with a slightly soiled spine. A bump to fore-edge. 445, (3) pp. First edition (20 Septembre, 1967, numéro 630) of Derrida's seminal main work, the foundational text for deconstructive criticism.1967 marks a turning point in the history of modern philosophy, constituting the birth of "Deconstruction". In this one year, Derrida publishes all of his three break-through books, "De la grammatologie", "L'écriture et la difference" and "La Voix et le phenomene", profoundly altering the course of modern thought. Although all three books are responsible for the introduction of Deconstruction, it is primarily "De la Grammatologie", Derrida's magnum opus, that has come to be associated with this groundbreaking concept."Jacques Derrida's revolutionary theories about deconstruction, phenomenology, psychoanalysis, and structuralism, first voiced in the 1960's, forever changed the face of European and American criticism. The ideas in "De la grammatologie" sparked lively debates in intellectual circles that included students of literature, philosophy, and the humanities, inspiring these students to ask questions of their disciplines that had previously been considered improper. Thirty years later, the immense influence of Derrida's work is still igniting controversy..." (Review, Spivak's translation of Derrida's "Of Grammatology", 1997).Derrida's concern is to bring to light the binary schema that is hidden in all kinds of texts and ideas of culture. In the present text Derrida brilliantly reveals some of the principles of deconstruction, not through theoretical explication, but, rather, by demonstration, showing that the arguments promulgated by their subject-matter exceed and contradict the oppositional parameters in which they are situated. Put into other words, deconstruction seeks to expose, and then to subvert, the various binary oppositions that undergird our dominant ways of thinking.The ideas that Derrida here present have had an enormous impact on a number of the human sciences, including psychology, literary theory, cultural studies, linguistics, feminism, sociology and anthropology. Due to this work, a whole new world of problematic suppression and marginalisation has become apparent, making "De la grammatologie" one of the most important philosophical works of the later part of the 20th century. "One of the major works in the development of contemporary criticism and philosophy". (J. Hillis Miller, Yale University).

Reasearch progressed so rapidly in this erea that the second edition, published only a year later, had to be enlarged by fifity percent.
